Description

  The present invention provides, for example, an X-ray irradiation direction clarifier that preliminarily indicates an X-ray irradiation direction when taking an X-ray photograph of an affected area using an intraoral X-ray imaging apparatus that images the oral cavity in dental practice, The present invention relates to an irradiation tube provided with an X-ray irradiation direction clarifier and an X-ray generation device provided with an X-ray irradiation direction clarifier.

In dental practice, it is important to check an image obtained by photographing the inside of the oral cavity with X-rays and judge the degree of disease and the result of treatment. For example, as an X-ray imaging apparatus therefor, there are a panoramic X-ray imaging apparatus, an X-ray CT imaging apparatus, a cephalo X-ray imaging apparatus, a tomography apparatus, an intraoral X-ray imaging apparatus called a dental X-ray imaging apparatus, and the like.
The above-described medical care is a concept including diagnosis, medical examination, and treatment.

  Among these X-ray imaging apparatuses, the intraoral X-ray imaging apparatus inserts an X-ray detector such as a dental X-ray film into the oral cavity and adjusts the position of the X-ray generation apparatus with respect to the affected area. Then, X-rays are emitted from the X-ray generator, and an image is taken with an X-ray detector inserted into the oral cavity.

In addition, if the irradiation direction of the X-rays emitted from the X-ray generator is shifted with respect to the X-ray detector, an accurate image cannot be acquired and re-imaging is forced. There was a problem of increasing
Therefore, a plurality of light guides that illuminate the visible light forward in the vicinity of the tip of the cylindrical irradiation tube provided in front of the X-ray irradiation direction of the X-ray generator, and the visible light is on the X-ray irradiation axis. Irradiation cylinders arranged at equal intervals in the circumferential direction so as to intersect with each other have been proposed (see Patent Document 1).

  By attaching this irradiation tube to the X-ray generator and matching the intersection of visible light illuminated from the light guide to the affected area, the X-ray irradiation direction irradiated from the X-ray generator can be set in advance. It is said that an appropriate distance from the X-ray generator to the affected part can be adjusted.

  However, the skin on the surface of the affected area onto which visible light is projected has a three-dimensional shape, and it has been difficult to accurately match the intersection of visible light with the affected area. More specifically, in the irradiation tube, the visible light illuminated from each of the light guides arranged at equal intervals in the cylindrical circumferential direction approaches the intersection on the X-ray irradiation axis, and the intersection After passing, they are separated by an arrangement that is axially symmetric with respect to the X-ray irradiation axis.

Then, when multiple visible lights are projected on the skin on the affected surface, the visible light is projected on the near side of the intersection, that is, the distance is shorter than the predetermined distance. visible light side is projected, i.e. the distance can not be determined whether such that longer than the predetermined distance, while checking the projected visible light, crossing the X-ray generator is moved one not a little It was necessary to find the part and move it to the appropriate position.

  The present invention provides an X-ray irradiation direction clarifier that can easily adjust the position of an X-ray generator to an appropriate position with respect to an affected area while projecting illuminated visible light onto the skin of the affected area. An object of the present invention is to provide an irradiation tube provided with an irradiation direction clarifier and an X-ray generation apparatus provided with an X-ray irradiation direction clarifier.

The present invention includes an X-ray irradiating means, and is disposed inside an X-ray generator having an irradiating cylinder attached to an irradiation cylinder mounting opening provided in front of the X-ray irradiating means. composed of a plurality of illuminating means for illuminating, the plurality of illuminating means, illumination axis for illuminating the該照light means, through from the X-ray irradiation means of the inside of the irradiation tube through which X-rays radiated toward the front together through space, the the X-ray irradiation axis and the axis of symmetry of the X-ray, and, characterized in that an arrangement the X-ray irradiation direction explicitly device so as to intersect on the X-ray irradiation axis.

  The above-mentioned illumination formats include light color, shape, brightness, light emission pattern, intensity (illuminance), for example, the type of light emitted from different light sources such as a laser irradiation source that emits laser light and an LED light emitting device, or a combination thereof. It can be.

The above-mentioned X-ray irradiation direction clarifier is an X-ray irradiation direction clarifier assembled to the X-ray generator, an X-ray irradiation direction clarifier assembled to a part to be mounted on the X-ray generator, or an X-ray generator X-ray irradiation direction clarifier attached to the part to be performed.
In addition, the intersection part on the X-ray irradiation axis of visible light illuminated from a plurality of illumination means is a measure of the distance to the skin on the affected surface relative to the X-ray generator.

The irradiation tube includes an irradiation tube integrally configured at the X-ray irradiation port of the X-ray generation device, or an irradiation tube configured separately, and is an irradiation tube that is detachably attached to the X-ray irradiation port. be able to.

According to the present invention, it is possible to easily adjust the position of the X-ray generator to an appropriate position with respect to the affected area while projecting the illuminated visible light onto the skin on the affected area surface.
Specifically, the visible light illuminated from a plurality of illumination means approaches the crossing portion on the X-ray irradiation axis, and after passing the crossing portion, the positional relationship is symmetric with respect to the X-ray irradiation axis. The visible light emitted from each illuminating means is in a different illumination format, so it is easy to grasp the front-to-back relationship to the intersection just by checking the positional relationship of the visible light projected on the skin on the affected area. can do.

  Specifically, if there is only one visible light projected onto the skin on the affected surface, that is, if the visible light emitted from a plurality of illumination means is combined, it indicates that the position is appropriate for the intersection. When visible light of different illumination formats is projected in a positional relationship while being arranged in the X-ray irradiation direction clarifier, visible light is projected in front of the intersection, that is, the distance is more than a predetermined distance It will be short.

  On the other hand, compared to the positional relationship in which the visible light of different illumination types projected on the skin of the affected surface is arranged in the X-ray irradiation direction clarifier, the positional relationship is axisymmetric with respect to the X-ray irradiation axis, It can be determined that visible light is projected behind the intersection, that is, the distance is longer than a predetermined distance.

In this way, the visible light illuminated from each illumination means is illuminated in different illumination formats, so it is easy to check the positional relationship of the visible light projected on the skin on the affected surface, and easily The relationship can be grasped, and the X-ray generator can be easily adjusted to an appropriate position with respect to the affected area while projecting the illuminated visible light onto the skin on the affected area.

The above-mentioned transparency is not only transparent but also a concept including an opaque one that is transparent to the extent that visible light can be visually recognized from the outside.

According to the present invention, visible light illuminated from the illumination means can be visually recognized from the outside. Therefore, in the case of an opaque tube, there is no waste of going around to a position where visible light can be seen, checking the projected visible light and adjusting the position, and safely and promptly projecting the projected visible light. The position of the X-ray generator can be easily adjusted to an appropriate position with respect to the affected part while checking the light.

As an aspect of the present invention, the plurality of illumination means can be arranged at equal intervals around the X-ray irradiation axis.
According to the present invention, it is possible to arrange a plurality of illumination means so that the illumination axis is axially symmetric with the X-ray irradiation axis and so as to reliably intersect on the X-ray irradiation axis. Specifically, the illumination direction relative to the X-ray irradiation axis of each illumination means and the same direction, the illumination means, at regular intervals to the X-ray irradiation tube or the X-ray generator so as to be axisymmetric about said X-ray irradiation axis A plurality of illuminating means can be arranged so that the illuminating axes cross the X-ray irradiation axis with certainty easily and reliably just by arranging them.

In addition, by confirming the interval of visible light projected on the skin on the affected area surface, it is possible to confirm the inclination direction of the X-ray generator with respect to the affected area surface.
Specifically, for example, when three or more illumination means are arranged at equal intervals around the X-ray irradiation axis, if the positional relationship of visible light projected onto the skin on the affected surface is not equal, the X-ray irradiation axis Can be confirmed to be inclined with respect to the affected surface.

  As an aspect of the present invention, the different illumination formats may be any one of light color, cross-sectional shape, brightness, and light emission pattern, or a combination thereof.

  Note that the above-described different illumination formats are only used when all of the visible light illuminated from each illumination means is different in any one of light color, cross-sectional shape, brightness, and light emission pattern, or a combination of them. For example, when three or more illuminating means are provided, the visible color irradiated from each illuminating means is different such that the color of light is different in one combination of visible light and the cross-sectional shape is different in another combination of visible light. The concept includes patterns with different illumination formats that can identify light.

  According to the present invention, visible light projected from each illuminating means is easily identified visually, the positional relationship of visible light projected on the skin on the affected area surface is surely grasped, and the X-ray generator is applied to the affected area. The position can be adjusted efficiently to an appropriate position.

Further, as an aspect of the present invention, the different illumination formats may be illumination formats that are combined in an intersecting state to form a desired illumination format.

According to the present invention, the distance of the intersecting portion on the X-ray irradiation axis with respect to the X-ray generator can be adjusted to a desired distance. For example, since the position of the intersection with the X-ray generator on the X-ray irradiation axis may be adjusted in accordance with the state of the affected part, the length of the irradiation tube attached to the X-ray generator, etc., the illumination means Convenience is improved by providing an angle adjusting means for adjusting the illumination angle.

As an aspect of the present invention, the visible light illuminated from the illumination means is illuminated with a color dissimilar to skin color.
A color dissimilar to the skin color can be visible light having a small yellow component.

  According to the present invention, visible light projected onto the skin on the affected surface can be easily identified visually. Specifically, when the visible light illuminated from the illumination means is illuminated with a color similar to the skin color, the visibility of the visible light projected on the skin on the affected surface, which is the skin color, is low, but the color is not similar to the skin color. By illuminating, the visibility of visible light projected onto the skin on the affected area surface can be improved.

As an aspect of this invention, the illumination means can be arranged so as to intersect on the X-ray irradiation axis in front of the tube tip of the irradiation tube .

According to the present invention, it is possible to easily adjust the position of the X-ray generator to an appropriate position with respect to the affected area while projecting visible light irradiated from the X-ray irradiation direction clarifier onto the skin on the affected area surface.

Further, as an aspect of the present invention, the illuminating means can be constituted by two illuminating means, arranged symmetrically with respect to the X-ray irradiation axis, and arranged so that the illuminating axis is horizontal.
According to the present invention, it is possible to easily adjust the position of the X-ray generator to an appropriate position with respect to the affected part while confirming the visible light that is illuminated in the horizontal direction and projected onto the skin on the affected part surface.

  Specifically, in general, the position of the X-ray generator can be adjusted while maintaining a horizontal rotation axis that rotates in the vertical direction. In such an X-ray generator capable of adjusting the position while maintaining the horizontal state, the two illumination means are arranged symmetrically with respect to the X-ray irradiation axis, and are arranged so that the illumination axis is horizontal. Accordingly, it is possible to easily adjust the position of the X-ray generation device to an appropriate position with respect to the affected part while always projecting visible light that is horizontally illuminated onto the skin of the affected part.

Specifically, since the operation switch for turning on the illumination means is composed of a planar contact detection switch and is disposed on at least a part of the surface of the X-ray generator including the irradiation tube, the visible light illuminated from the illumination means is displayed. In order to adjust the position of the X-ray generation apparatus to an appropriate position with respect to the affected part while viewing the light, the surface-shaped contact detection switch can be turned on when contacting the X-ray generation apparatus. Therefore, the operability is improved as compared with the case where another operation switch is provided.

  In addition, the control unit controls the illumination unit on based on the ON operation of the operation switch, and also controls the illumination unit to turn off after a predetermined time has elapsed, so that visible light emitted from the illumination unit is projected from the X-ray generator to the X It is possible to prevent X-ray imaging by irradiating a line.

  As shown in FIG. 1, an intraoral X-ray imaging apparatus 1, which is called a dental X-ray imaging apparatus, is disposed on, for example, a base 2 placed on a floor surface and an upper surface 2 a of the base 2, and a patient is seated on the floor 2. Seat 3, a stand pole 4 that is implanted on the upper surface 2 a of the base 2 and functions as a support, an arm 5 that is rotatably connected to the upper end of the stand pole 4, and an X that will be described later at the tip of the arm 5. A head support 6 that suspends and supports the line head 10, an X-ray head 10 that is rotatably connected to the head support 6, a backrest 7 that is fixed to the seat 3 side of the stand pole 4, and a stand pole 4 and the inverter box 8 fixed to the opposite side of the seat 3.

  The seat 3 is configured such that the height of the seat cushion portion 3 a having a circular shape in plan view can be adjusted with respect to the base 2. The stand pole 4 has a quadrangular prism shape, and is formed at a height that is higher than the head of a normal person seated on the seat cushion portion 3a of the seat 3. Therefore, the backrest 7 fixed to the seat 3 side of the stand pole 4 functions as a backrest of the patient seated on the seat 3. The seat 3 and the backrest 7 are configuration examples of subject support means for supporting the patient's waist and back, but a chair with an integrated backrest and seat may be used.

  The arm 5 is perpendicular to the upper end 4a of the stand pole 4 with respect to the horizontal first arm 5a that rotates about a vertical rotation axis and the distal end 5aa of the first arm 5a. And the second arm 5b that is inclined downward about the rotation axis.

  The head support 6 is formed in a downward inverted L-shape that rotates about the vertical rotation axis with respect to the distal end portion 5ba of the second arm 5b, and is formed on the side surface 10b of the X-ray head 10 at the lower end portion 6a. On the other hand, it is configured to rotate around a horizontal rotation axis 6ax, and the irradiation tube 20 mounted on the front surface 10a of the X-ray head 10 can swing in the vertical direction. The arm 5 and the head support 6 are configuration examples of X-ray generator support means for supporting the X-ray head 10 which is an X-ray generator.

  An X-ray head 10 corresponding to an X-ray generator is formed in a rectangular parallelepiped shape that is vertically long and low in plan view, and an X-ray tube, a high-pressure generator, etc. are arranged inside and covered with an X-ray shielding member. A radiation irradiation means 12 (FIG. 2) is provided, the front surface 10a is allowed to mount the irradiation tube 20, and an irradiation tube mounting port 11 corresponding to the X-ray irradiation port is provided, and a rear end side corner portion of the upper surface 10c is described later. A planar operation switch 40 for turning on the visible light source 30 is provided. The irradiation tube 20 of the X-ray head 10 has a hollow cylindrical shape and is formed of a transparent resin having transparency, and is detachably mounted.

  In the stand pole 4, a control unit that controls irradiation of X-rays irradiated from the X-ray head 10 is built in an inverter box 8 fixed on the opposite side of the seat 3.

  In the intraoral X-ray imaging apparatus 1 configured as described above, a CCD sensor, a MOS sensor, a CMOS sensor, other solid-state imaging devices and imaging plates which are irradiated with X-rays from the X-ray head 10 and set in the patient's oral cavity. An X-ray image of the affected area can be taken with a detector (not shown) such as an X-ray imaging means or an X-ray film.

  Further, for the imaging, the X-ray head 10 can be moved in the horizontal direction and adjusted in direction with respect to the affected part of the patient seated on the seat 3 by the arm 5 and the head support 6.

The head support 6 rotates about the vertical rotation axis with respect to the distal end portion 5ba of the second arm 5b, and at the lower end portion 6a of the head support 6 with respect to the side surface 10b of the X-ray head 10. Thus, it can be supported in the vertical direction around the horizontal rotation axis 6ax. Therefore, the position and orientation of the X-ray head 10 can be adjusted by the arm 5 and the head support 6.
In the intraoral X-ray imaging apparatus 1 described above, the stand pole 4 is erected on the base 2, and the seat 2 on which the patient sits is provided on the base 2, but the stand pole 4 is directly fixed to the floor or wall. It may be in such a form. Further, the conventional mouth such as a configuration in which the X-ray head 10 is movably arranged from the ceiling or wall via an arm mechanism, or a caster is attached below the base 2 on which the stand pole 4 is erected. Any of the configurations of the normal X-ray imaging apparatus can be employed.

  Next, the X-ray head 10 will be described in detail. The X-ray head 10 that irradiates the affected part with the X-ray beam 200 through the penetration space 20a of the irradiation tube 20 mounted on the irradiation tube mounting port 11 of the front surface 10a is an X-ray that generates the X-ray beam 200 therein. Corresponding to the generating means 12 and the illuminating means, a visible light source 30 for illuminating the visible light beam 100 is provided.

  Specifically, the X-ray irradiating means 12 irradiates the X-ray beam 200 through the irradiation tube mounting port 11 provided on the front surface 10a of the X-ray head 10 toward the front (lower right in FIG. 2). The optical axis of the X-ray beam 200 irradiated from the X-ray irradiation means 12 is taken as an X-ray irradiation axis 200L.

  The visible light source 30 is disposed inside the X-ray head 10 in the irradiation tube mounting port 11 and illuminates the visible light beam 100 forward. The optical axis of the visible light beam 100 emitted from the visible light source 30 is defined as a visible light illumination axis 100L (see FIG. 3).

  As shown in FIG. 3A, two visible light sources 30 are arranged symmetrically with respect to the X-ray irradiation axis 200 </ b> L, and visible light irradiation of the visible light beam 100 emitted from each visible light source 30 is performed. The axis 100L is arranged in a direction that intersects at an intersection point P on the X-ray irradiation axis 200L, that is, in a C-shaped plan view toward the front of the X-ray irradiation axis 200L.

For example, as shown in FIG. 2, the illumination control of the visible light source 30 is performed by a planar contact detection switch provided on the upper surface 10 c of the X-ray head 10 that is unconsciously touched when the X-ray head 10 is positioned. Based on the contact ON operation by the operation switch 40 to be configured, the control unit (not shown) built in the inverter box 8 is turned ON, and if it is turned OFF after a predetermined time has passed, the illumination and extinction are performed one by one. Therefore, convenience is improved because there is no need to perform a switch operation.
Further, the intersection point P described above is a distance to the skin on the surface of the affected area with respect to the X-ray head 10 and is a measure of a distance suitable for X-ray imaging.

  Subsequently, the two visible light sources 30 arranged in the horizontal direction inside the X-ray head 10 and symmetrically with respect to the X-ray irradiation axis 200L and constituting the X-ray irradiation direction clarifier, that is, the X-ray irradiation axes are arranged. The visible light source 30 arranged at equal intervals as the center will be described in detail with reference to FIG. In FIG. 3, the hatched diagram shows the projected shape on the vertical projection plane on which the visible light emitted from the visible light source 30 is projected at each position where the projection plane is arranged. Show.

  The two visible light sources 30 illuminate the visible light beam 100 in different illumination formats. For example, in the pattern shown in FIG. 3A, the visible light source 30 on the left side and the red circular visible light beam 101 are illuminated toward the front in the irradiation direction of the X-ray irradiation axis 200L so that the color of the visible light beam 100 is different. The visible light source 30 on the right side is composed of a blue circular visible light source 32 that illuminates the blue circular visible light beam 102.

In this case, a red circular visible light beam is illuminated from the red circular visible light source 31 on the left side of the X-ray irradiation axis 200L, and a blue circular visible light is emitted from the blue circular visible light source 32 on the right side of the X-ray irradiation axis 200L. The beam is illuminated. At the intersection point P of the X-ray irradiation axis 200L, the red circular visible light beam 101 and the blue circular visible light beam 102 are combined, and the red and blue circles overlap to form a magenta circle. From the intersection point P, the red circular visible light beam 101 is on the right side with respect to the X-ray irradiation axis 200L, and the blue circular visible light beam 102 is on the left side with respect to the X-ray irradiation axis 200L. And the interval gradually increases.
Note that the range from the visible light source 30 to the intersection point P is the proximity range Hn, and the area in front of the illumination direction from the intersection point P is the remote range Hf.

  Thus, the visible light source 30 (31, 32) is configured by configuring the two visible light sources 30 with the red circular visible light source 31 on the left side and the blue circular visible light source 32 on the right side with respect to the X-ray irradiation axis 200L. When the visible light beam 100 (101, 102) is projected onto the skin on the affected surface, and the visible light beam 100 having a substantially magenta color projection shape is projected, the skin on the affected surface is at the intersection point P. When the red circular visible light beam 101 is projected on the left side and the blue circular visible light beam 102 is projected on the right side, the distance from the visible light source 30 to the skin on the affected surface is the proximity range Hn, and the red circular visible light is visible. When the light beam 101 is projected on the right side and the blue circular visible light beam 102 is projected on the left side, the distance from the visible light source 30 to the skin on the affected surface is a remote range Hf. It is seen.

  Note that the red color of the red circular visible light beam 101 illuminated from the red circular visible light source 31, the blue color of the blue circular visible light beam 102 illuminated from the blue circular visible light source 32, and the red circular visible light beam 101 and the blue circular visible light. Since all the magenta colors obtained by combining the beams 102 at the intersection point P are dissimilar to the skin color, they are highly visible when projected onto the skin on the affected surface.

  As described above, the color that is highly visible and dissimilar to the skin color when projected onto the skin of the affected surface is visible light of a color with a small yellow component, and the above-described red and blue, and the synthesized magenta color. In addition to the combination of green and blue, a combination of green, blue, and a synthesized cyan color may be used.

  Further, as another pattern in which the two visible light sources 30 illuminate the visible light beam 100 in different illumination formats, as shown in FIG. 3B, the visible light on the left side is different so that the projected shape of the visible light beam 100 is different. The light source 30 is composed of an inverted D-type visible light source 33 that illuminates an inverted D-type visible light beam 103 whose projection shape is an inverted D-type, and the right-side visible light source 30 is a D-type visible light beam whose projection shape is a D-type. A D-type visible light source 34 that illuminates 104 can be used. Further, it can be determined from the projected shape illuminated on the skin surface whether the visible light beam 100 on the right side or the left side is one, or whether the two intersect each other (intersection point P).

  As described above, the two visible light sources 30 are constituted by the left-side inverted D-type visible light source 33 and the right-side D-type visible light source 34 with respect to the X-ray irradiation axis 200 </ b> L. In the projected state, at the intersection point P, the inverted D-type visible light beam 103 and the D-type visible light beam 104 are combined to form a projected shape. That is, the projection shape projected at the intersection point P, that is, the illumination shape illuminated with respect to the intersection point P is illuminated from each visible light source 30 (33, 34) so as to have a desired circular shape at the intersection point P. The illumination shape (projection shape) of the visible light beam 100 is set to the inverse D type and the D type.

  Therefore, when the visible light beam 100 (103, 104) is projected from the visible light source 30 (33, 34) onto the skin of the affected area, the skin on the affected area crosses when the circular visible light beam 100 is projected. When the inverse D-type inverse D-type visible light beam 103 is projected on the left side and the D-type D-type visible light beam 104 is projected on the right side at the position of the point P, the surface of the affected area with respect to the visible light source 30 is exposed to the skin. The distance is the proximity range Hn. When the inverted D-type inverted D-type visible light beam 103 is projected on the right side and the D-type D-type visible light beam 104 is projected on the left side, the distance from the visible light source 30 to the skin on the affected area surface. It can be seen that is the remote range Hf. In this way, by combining the D-type and inverse D-type visible light beams, the distance to the skin on the affected surface can be grasped without changing the color. Needless to say, these colors may be different.

  In the above description, the color and illumination shape (projection shape) of the visible light beam 100 illuminated from the visible light source 30 are made different as the illumination format of the visible light beam 100 illuminated from the two visible light sources 30. In addition to the color and the illumination shape (projection shape), the brightness, the light emission pattern, and the intensity (illuminance) may be varied, or a combination thereof may be used. In addition, when making a light emission pattern different, for example, one light may be irradiated by blinking, and both the lights may be irradiated by blinking, and the blinking pattern may be made different.

  As described above, in the intraoral X-ray imaging apparatus 1 having the X-ray head 10 provided with the visible light source 30 (31, 32 or 33, 34) that illuminates in different illumination formats, the X-ray head 10 applies X to the affected area. Before the X-ray imaging is performed by irradiating the line beam 200, the visible light beam 100 illuminated from the visible light source 30 is projected onto the skin on the affected surface, and an appropriate position with respect to the skin on the affected surface, that is, a desired illumination format. The X-ray head 10 can be adjusted to be the intersection point P projected at.

  Specifically, the visible light beam 100 is illuminated from a visible light source 30 having a different illumination format, and projected onto the skin on the affected surface. At this time, if the projection format (illumination format: color or shape) is the same as the arrangement of the two visible light sources 30 with respect to the X-ray irradiation axis 200L, the distance to the X-ray head 10 with respect to the skin on the surface of the affected area is in the proximity range. Since it is Hn, the position of the X-ray head 10 is adjusted in the direction away from the skin on the affected surface so that the skin on the affected surface becomes the intersection point P.

  On the other hand, if the projection format (illumination format: color or shape) is opposite to the arrangement of the two visible light sources 30 with respect to the X-ray irradiation axis 200L, the distance to the X-ray head 10 relative to the skin on the affected surface. Is the remote range Hf, the position of the X-ray head 10 is adjusted so as to approach the skin on the affected surface so that the skin on the affected surface becomes the intersection point P.

  In this way, the visible light beam 100 illuminated from the two visible light sources 30 is projected onto the skin on the affected surface, and the positional relationship with respect to the X-ray irradiation axis 200L is confirmed, whereby the X-ray head 10 with respect to the affected surface skin. It is possible to immediately confirm whether the distance is within the proximity range Hn or the remote range Hf.

  Further, since the two visible light sources 30 are arranged so as to be symmetrical and horizontal with respect to the X-ray irradiation axis 200L, the X-ray head 10 is rotated about the rotation axis 6ax by the arm 5 and the head support 6. Since the position can be adjusted while maintaining the level, the two visible light beams 100 projected onto the skin on the affected surface are always in a horizontal state, and the position of the X-ray head 10 with respect to the skin on the affected surface can be easily adjusted. .

Further, since the transparent irradiation cylinder 20 is mounted, the visible light beam 100 illuminated from the visible light source 30 can be visually recognized from the outside. Therefore, in the case of an opaque irradiation tube that is not transparent, there is no waste of going around to a position where the visible light beam 100 can be visually confirmed, checking the projected visible light beam 100 and adjusting the position of the X-ray head 10, etc. While confirming the projected visible light beam 100 safely and quickly, the X-ray head 10 can be easily adjusted to an appropriate position with respect to the affected area.
Therefore, an accurate and accurate image can be taken with a detector such as a CCD sensor or an imaging plate, and appropriate medical care can be performed based on the accurate image.

  Further, the two visible light sources 30 are arranged so that the visible light illumination axis 100L passes through the through space 20a of the irradiation cylinder 20 and intersects on the X-ray irradiation axis 200L ahead of the tube tip of the irradiation cylinder 20, Compared with the case where the visible light illuminating axis 100L passes the outside of the irradiation tube 20 and intersects on the X-ray irradiation axis 200L ahead of the tube tip, the setting range of the distance from the tube tip to the intersection point P is widened and versatility is increased. Rise.

  Next, an automatic illumination angle adjustment mechanism 50 corresponding to an automatic angle adjustment unit that automatically adjusts the illumination angles of the two visible light sources 30 according to the type (cylinder length) of the irradiation cylinder 20 will be described with reference to FIGS. To do.

  4 to 6, (a) shows a cross-sectional view when the short irradiation tube 21 with a short tube length is mounted, and (b) shows a case with the long irradiation tube 22 with a long tube length mounted. A cross-sectional view is shown.

  The illumination angle of the visible light source 30 is determined by the distance from the X-ray head 10 to the intersection point P where the visible light illumination axes 100L illuminated from the two visible light sources 30 intersect on the X-ray irradiation axis 200L. It is convenient for the X-ray head 10 to adjust the illumination angle and appropriately set the distance to the intersection point P according to the condition of the skin on the affected area such as the age of the patient and the imaging region, or the tube length of the irradiation tube 20. It leads to improvement in performance. Among them, the illumination angle automatic adjustment mechanism 50 described here automatically adjusts the illumination angle of the visible light source 30 according to the tube length of the irradiation tube 20.

  The irradiation cylinder 20 that is detachably attached to the X-ray head 10 has a reduced diameter portion on the rear side (lower side in FIGS. 4 to 6) of the irradiation cylinder 20 and is inserted into the irradiation cylinder attachment port 11. 23. In the illumination angle automatic adjustment mechanism 50 a shown in FIG. 4, the length of the insertion reduced diameter portion 23 of the short irradiation tube 21 in the X-ray irradiation axis direction is longer than the insertion reduced diameter portion 23 of the long irradiation tube 22. .

  As an example of the automatic illumination angle adjusting mechanism 50, an automatic illumination angle adjusting mechanism 50a shown in FIG. 4 has an axis that allows the visible light source 30 to pivot in a horizontal plane at the rear end portion of the visible light source 30 that illuminates the visible light beam 100. A pivot shaft 51 to be supported is fixed to an appropriate portion inside the X-ray head 10, and a coil spring 52 that urges the front end of the visible light source 30 outward in the width direction, and obliquely forward from the front end of the visible light source 30. And an arm 53 extending toward the rear end face of the insertion reduced diameter portion 23.

  With this configuration, when the illumination angle automatic adjustment mechanism 50 a inserts the reduced diameter portion 23 into the irradiation tube mounting port 11 and mounts the irradiation tube 20 (21, 22), the rear end surface of the reduced diameter portion 23 becomes the arm 53. Therefore, the visible light source 30 pivots the front of the visible light source 30 inward in the width direction about the pivot shaft 51 against the biasing force of the coil spring 52.

  At this time, since the insertion reduced diameter portion 23 of the long irradiation tube 22 is shorter than the insertion reduced diameter portion 23 of the short irradiation tube 21, the amount of pressing the arm 53 backward is small, and the pivot toward the inner side in the width direction is small. The amount of movement is reduced, and the illumination direction of the visible light illumination axis 100L of the visible light source 30 is shallower than that of the short illumination tube 21, and the distance from the tube tip of the illumination tube 20 to the intersection point P can be set longer.

  As an example of the automatic illumination angle adjustment mechanism 50, the second automatic illumination angle adjustment mechanism 50b shown in FIG. 5 pivots the visible light source 30 in a horizontal plane at the rear end portion of the visible light source 30 that illuminates the visible light beam 100. A pivot shaft 51 that pivotally supports is provided, and a connecting member 54 that connects the front ends of the left and right visible light sources 30 is provided.

  Unlike the illumination angle automatic adjusting mechanism 50a described above, the insertion reduced diameter portion 23 of the short irradiation cylinder 21 and the insertion reduction diameter section 23 of the long irradiation cylinder 22 are formed with the same length. A pressing convex portion 24 that presses the central portion of the connecting member 54 rearward is provided at the central portion in the width direction of the insertion reduced diameter portion 23. The connecting member 54 that connects the front ends of the left and right visible light sources 30 has flexibility and elasticity.

  With this configuration, the second illumination angle automatic adjustment mechanism 50b inserts the reduced diameter portion 23 into the irradiation tube mounting port 11 and mounts the irradiation tube 20 (21, 22). 24, the central portion of the connecting member 54 is pressed rearward, so that the connecting member 54 bends in a curved state protruding backward, and the left and right visible light sources 30 pivot forward inward in the width direction with the pivot shaft 51 as an axis. . On the other hand, since the long irradiation tube 22 does not include the pressing convex portion 24, the connecting member 54 does not bend and the visible light source 30 does not pivot.

  Since the connecting member 54 has flexibility and elasticity, when the short irradiation tube 21 is removed, the bending due to the pressing convex portion 24 is eliminated, and the visible light source 30 is restored to the original by the self-elastic force of the connecting member 54. Pivot to state and restore. In the above description, the pressing projection 24 is not provided on the long irradiation tube 22, but the pressing projection 24 having a smaller amount of protrusion to the rear than the pressing projection 24 of the short irradiation tube 21 may be provided. Good.

  As an example of the automatic illumination angle adjustment mechanism 50, a third automatic illumination angle adjustment mechanism 50c shown in FIG. 6 pivots the visible light source 30 in a horizontal plane at the rear end portion of the visible light source 30 that illuminates the visible light beam 100. A torsion spring 56 is provided that has a pivot shaft 51 that is pivotally supported, a projection piece 55 that projects forward in the vicinity of the front end of the visible light source 30, and further biases the projection piece 55 outward in the width direction. It has.

  Then, the insertion reduced diameter part 23 of the short irradiation cylinder 21 is formed longer than the insertion reduction diameter part 23 of the long irradiation cylinder 22, and the protruding piece 55 is brought into contact with the rear end inner part of both of the insertion reduction diameter parts 23. An allowable taper portion 23a is formed. Moreover, the contact part 55a of the protrusion piece 55 which contact | abuts to the taper part 23a is formed in circular arc shape. Although not shown, the light source 30 is urged toward the protruding piece 55 by an urging means such as a spring. Further, the light source 30 may be fixed to the protruding piece 55 without providing the pivot shaft 51.

  With this configuration, the third illumination angle automatic adjustment mechanism 50c inserts the insertion diameter-reduced portion 23 into the irradiation tube mounting port 11 and mounts the irradiation tube 20 (21, 22), so that the tapered portion of the insertion diameter-reduced portion 23 is inserted. 23 a abuts against the abutting portion 55 a of the projecting piece 55 and presses the visible light source 30 rearward through the projecting piece 55.

  At this time, since the taper portion 23a and the contact portion 55a are in contact with each other in the direction intersecting the front-rear direction, the taper portion 23a and the contact portion 55a resist the urging force of the torsion spring 56 and Pivot forward inward in the width direction. Since the pushing amount of the tapered portion 23a through the protruding piece 55 is larger in the short irradiation tube 21 than in the long irradiation tube 22, the pivoting amount of the visible light source 30 by the short irradiation tube 21 is increased. 4 to 6 illustrate an example in which the visible light source 30 is moved. However, the visible light source 30 is fixed, and the angles of mirrors (or optical means such as prisms) provided in the long irradiation tube and the short irradiation tube are different. The illumination angle may be automatically adjusted by adjusting the illumination angle.

  4 to 6 so far, the visible light source 30 is disposed inside the X-ray head 10 so that the visible light illumination axis 100L passes through the through space 20a of the irradiation tube 20 and intersects the X-ray irradiation axis 200L. The illumination angle automatic adjustment mechanism 50 of the visible light source 30 that illuminates the visible light illumination axis 100L has been described. Subsequently, as an example of the illumination angle automatic adjustment mechanism 50, as shown in FIG. A fourth illumination angle automatic adjustment mechanism 50d that is disposed on the front surface 10a of the head 10 and illuminates the visible light beam 100 from the outside of the irradiation tube 20 will be described.

  7, 8A, and 8B are perspective views of the X-ray head 10 in which the visible light source 30 is disposed on the front surface 10a of the X-ray head 10, and FIG. FIG. 8B shows a cross-sectional view when a long irradiation tube 22 having a long tube length is mounted. FIG.

When the visible light source 30 is mounted on the front surface 10a of the X-ray head 10, the X-ray head 10 is mounted through a through hole 30a provided in the front surface 10a.
In the fourth automatic illumination angle adjustment mechanism 50d, a pivot shaft 51 that pivotally supports the visible light source 30 so as to be pivotable in a horizontal plane is provided near the front in the longitudinal direction of the visible light source 30 that illuminates the visible light beam 100. The visible light source 30 includes a protruding piece 57 that protrudes toward the center in the width direction near the rear end. Further, biasing means (not shown) biases the front of the visible light source 30 outward in the width direction, that is, the protruding piece 57 is biased forward.
And on the rear end side of the insertion reduced diameter portion 23 of the long irradiation tube 22, a thin portion 23 b in which the thickness of the insertion reduced diameter portion 23 is formed thin is formed.

  With this configuration, the fourth illumination angle automatic adjustment mechanism 50d inserts the reduced diameter portion 23 into the irradiation tube mounting port 11 and mounts the irradiation tube 20 (21, 22). It abuts on 57 and is pushed backward, and the front of the visible light source 30 is pivoted inward in the width direction with the pivot shaft 51 as an axis. At this time, since the rear end of the insertion reduced diameter portion 23 of the long irradiation tube 22 is provided with a thin portion 23b, the pushing amount of the protruding piece 57 by the thin portion 23b is smaller than that of the insertion reduced diameter portion 23 of the short irradiation tube 21. The amount of pivoting of the visible light source 30 by the long irradiation tube 22 is reduced.

  As described above, the illumination angle automatic adjustment mechanism 50 (50a, 50b, 50c, 50d) that automatically adjusts the illumination direction of the visible light source 30, that is, the illumination angle of the visible light source 30, according to the type of the irradiation tube 20 is provided. As a result, various types of irradiation tubes 20 (21, 22) configured with tube lengths and tube diameters suitable for imaging conditions can be selected and used depending on the situation, and X-ray imaging can be performed. The distance to the X-ray head 10 and the irradiation cylinder 20 at the intersection point P on the X-ray irradiation axis 200L can be automatically adjusted according to the selected irradiation cylinder 20 (21, 22). Therefore, the operability can be improved as compared with the case where the illumination angle of the visible light source 30 cannot be adjusted or when the illumination angle of the irradiation tube 20 is manually adjusted in accordance with the attached irradiation tube 20.

Translucent resin corresponds to transparent resin,
The present invention is not limited to the embodiment described above.

  For example, in this embodiment, the visible light source 30 is attached to the X-ray head 10, but in order to attach the visible light source 30 to the X-ray head 10 that does not include the visible light source 30, means for attaching to the X-ray head 10 is provided. The provided visible light source 30 may be configured and attached to the X-ray head 10 later.

  Specifically, the visible light source 30 does not necessarily need to be fixedly provided on the X-ray head 10 or the irradiation cylinder 20, and although not illustrated, for example, only the visible light source 30 is provided on a ring-shaped member and the ring The member may be attached to the irradiation tube 20 so as to be detachable.

  In addition, as shown in FIG. 9, an irradiation tube with visible light source 26 (26 a, 26 b) in which a visible light source 30 is mounted on the irradiation tube 20 itself may be mounted on the X-ray head 10. FIG. 9A shows a cross-sectional view of the short irradiation tube 26a with a visible light source, and FIG. 9B shows a cross-sectional view of the long irradiation tube 26b with a visible light source.

  The irradiation tube with visible light source 26 (26a, 26b) is configured so that the thickness of the front tube body is thick enough to allow the visible light source 30 to be mounted therein, and the visible light source 30 is allowed to be mounted near the center in the thickness direction. A hole 25 is provided, and the visible light source 30 is inserted and fixed in the mounting hole 25. At this time, the illumination angle of the visible light source 30 may be set to the same angle between the short irradiation cylinder with a visible light source 26a and the long irradiation cylinder with a visible light source 26b, or the angle may be changed as shown in FIG.

  In this way, by attaching the visible light source 30 to the main body of the irradiation tube 20, the irradiation tube with visible light source 26 (26 a, 26 b) instead of the irradiation tube 20 even for the X-ray head 10 that does not include the visible light source 30. ) Is used to position the X-ray head 10 so that the X-ray beam 200 irradiated from the X-ray head 10 is at an appropriate position with respect to the affected area using the visible light beam 100 illuminated by the visible light source 30. Can be adjusted.

In addition, when using the irradiation tube 26 with a visible light source, a battery may be built in the irradiation tube as a power source.
In addition, the irradiation tube 20 may be provided integrally as a part of the X-ray head 10, even if it is not separate from the X-ray head 10. In this case, although the irradiation tube 20 cannot be replaced, for example, the irradiation tube portion such as the short irradiation tube 21 described above may constitute a part of the X-ray head 10 or the long irradiation tube 22 described above. Such an irradiation tube part may constitute a part of the X-ray head 10. In any case, the above-described visible light source 30 is provided with a fixed or automatic illumination angle adjustment mechanism 50.

  In the above description, in the X-ray head 10, the two visible light sources 30 are arranged so as to be axially symmetrical and horizontal with respect to the X-ray irradiation axis 200 </ b> L, but three or more visible light sources 30 are axially symmetric. You may arrange in.

  For example, in the case where three visible light sources 30 are arranged, as shown in FIG. 10A, the two visible light sources 30 on the upper side are arranged at equal intervals with respect to the X-ray irradiation axis 200L in the circumferential direction. Are arranged in an inverted equilateral triangle shape so that is horizontal. 10A and 10B are perspective views from the back side of the X-ray head 10 to which the three visible light sources 30 are attached.

  At this time, the three visible light sources 30 illuminate the red circular visible light source 31 that illuminates the red circular visible light beam 101, the blue circular visible light source 32 that illuminates the blue circular visible light beam 102, and the green visible light beam 105. A green visible light source 35 is arranged.

  With this configuration, the red circular visible light beam 101, the blue circular visible light beam 102, and the green visible light beam 105 are combined at the intersection point P and projected to white. Therefore, the projected white visible light synthesized at each visible light beam 100 (101, 102, 105) and the intersection point P in the state projected onto the skin of the affected area surface is also highly visible, and more accurately X The position of the line head 10 can be adjusted.

Further, by confirming the interval between the visible light beams 100 (101, 102, 105) projected on the skin on the affected area surface, the inclination direction of the X-ray head 10 relative to the skin on the affected area surface can be confirmed.
Specifically, for example, when three or more visible light sources 30 are arranged at equal intervals around the X-ray irradiation axis 200L, the positional relationship of the visible light beams 100 (101, 102, 105) projected onto the skin on the affected surface. If the distances are not equal, it can be confirmed that the X-ray irradiation axis 200L is inclined with respect to the skin on the affected surface.

  Note that the color combination is not limited to the above combination, and the visible light projected at the intersection point P is white as described above, as long as it is a combination of colors that are separated by a certain wavelength. can do.

  Further, as another pattern for mounting the three visible light sources 30 on the X-ray head 10, as shown in FIG. 10B, the same arrangement as the three visible light sources 30 shown in FIG. Arranges a collimating lens in front of the visible light source 30 on the lower side.

  With this configuration, the visible light beam 100 intersecting on the X-ray irradiation axis 200L is illuminated from the upper two visible light sources 30, and along the X-ray irradiation axis 200L from the lower visible light source 30 via the collimator lens. Further, it is possible to illuminate the vertical planar visible parallel light 100 ′.

  Thereby, the skin on the surface of the affected part is confirmed while confirming the visible light 100 ′ in the vertical direction illuminated from the X-ray head 10 that can always maintain a horizontal state and the visible light beam 100 intersecting on the X-ray irradiation axis 200L. In contrast, the position of the X-ray head 10 can be adjusted with higher accuracy.
