In addition, the same parts, arrows, etc. are denoted by the same symbols, and repeated explanations are omitted. the

Example 1

First, a schematic configuration of an X-ray imaging device 1 according to a first embodiment will be described with reference to FIG. 1 . Here, FIG. 1 shows a schematic configuration diagram of an X-ray imaging device 1 according to this embodiment. the

In FIG. 1 , the X-ray imaging device generally indicated by reference numeral 1 is a so-called ceiling-suspended X-ray imaging device, and a support 50 that moves up and down freely is provided on a carriage portion 30 . 30 moves in a horizontal plane on rails provided on the ceiling, and X-ray tube device 101 is rotatably installed on mounting member 70 rotatably provided on the lower portion of support column 50 . the

That is, the X-ray imaging apparatus 1 of this embodiment includes: a carriage unit 30 that moves in a horizontal plane via an X-axis mechanism unit 10 and a Y-axis mechanism unit 20 provided on the ceiling; The strut 50 on the carriage portion 30 ; the mounting member 70 rotatably mounted on the lower portion of the strut 50 via the swivel mechanism portion 60 ; The head 100 on the above-mentioned mounting member 70; the locking mechanism part (not shown) which fixes the movement of each of the above-mentioned plurality of mechanism parts; and the control device 5 which controls the locking mechanism. the

The X-axis mechanism unit 10 is composed of an X-axis frame 11 mounted on a ceiling surface, and the X-axis frame 11 includes a pair of parallel X-axis rails 12 . The Y-axis mechanism unit 20 is composed of a Y-axis frame body 21 movably held on the pair of X-axis rails 12 of the X-axis mechanism unit 10, and the Y-axis frame body 21 has a pair of parallel Y-axis rails 22. The carriage unit 30 is movably held on the above-mentioned pair of Y-axis rails 22 . the

The carriage part 30 is provided with the support|pillar 50 extended downward on the bottom part. The strut 50 is formed to be able to expand and contract in the vertical direction (Z-axis direction) via the Z-axis mechanism unit 40 provided inside. At the lower end of the support column 50 , there is provided a swivel mechanism 60 with the vertical direction (Z-axis) as the rotation axis, and a mounting member 70 is rotatably attached via the swivel mechanism 60 . the

The attachment member 70 is provided with the rotation mechanism part 80 provided with the horizontal 1st rotation shaft 81 on the front surface. Furthermore, the head 100 is attached to the rotation mechanism part 80 so as to be rotatable about the first rotation shaft 81 . An X-ray tube device 101 is provided on the head 100, and the X-ray tube device 101 is provided with an X-ray moving aperture 102 having an X-ray irradiation axis Q perpendicular to the first rotation axis 81. , that is, parallel to the Z axis. the

According to this configuration, the X-ray irradiation axis Q perpendicular to the horizontal first rotation axis 81 can be rotated around the first rotation axis 81, and the X-ray tube device 101 for irradiating X-rays can be rotated in the same direction as the X-ray irradiation axis Q. The axis Q parallel to the Z-axis rotates in the horizontal plane as the center, and then the horizontal plane moves up and down through the Z-axis mechanism part 40, and then the rotation axis (Z-axis) is controlled by the X-axis mechanism part 10 and the Y axis mounted on the ceiling surface. Since the shaft mechanism 20 moves within the horizontal plane formed, the X-ray irradiation axis Q can be directed to any affected part of the patient lying on the bed 4 arranged below or near the X-ray imaging apparatus 1 . Each mechanism unit that moves the X-ray irradiation axis Q includes a not-illustrated lock mechanism unit constituted by an electromagnetic lock mechanism, and can be moved by releasing each lock mechanism. the

The head 100 of this embodiment includes: an X-ray tube device 101 equipped with an X-ray moving aperture 102; an operation panel 110 disposed on the front surface of the X-ray tube device 101; a basic handle 120 ; and an operating handle 130 rotatably mounted on the basic handle 120 . In addition, in this embodiment, an example in which the control device 5 and the storage device 6 storing various information are provided on the operation panel 110 is shown, but the control device 5 and the storage device 6 can also be provided in the carriage part 30, and further One of them can be provided in the carriage unit 30 . the

In addition, one of the great features of the X-ray imaging apparatus 1 of this embodiment is that it includes an operation handle 130 rotatably attached via a second rotation shaft 131 that is connected to the second rotation shaft 131 . The above-mentioned first rotation shafts 81 are arranged in parallel with a predetermined interval d maintained. the

That is, in the prior art, in order to move the head 100, the basic handle 120 that is also adopted in this embodiment is utilized. Since the base handle 120 is a circular handle formed around the first rotation axis 81, as long as the ring-shaped base handle 120 is held, the head 100 can be moved arbitrarily and X-rays can be irradiated. Axis Q faces in any direction. However, although the base handle 120 has the above advantages, there is a problem that the position of the base handle 120 must always be maintained when moving. the

For example, when moving the head 100 up and down, the base handle 120 must be kept up and down, and when the head 100 is moved left and right or turned, the base handle 120 must be kept left and right, and when the X-ray irradiation axis Q is rotated, The basic handle 120 must be held and operated with two hands like a steering wheel of a car. And, in addition to changing the grip frequently, it is also necessary to work hard on the anti-slip aspect when changing the grip. In addition, two-handed operation becomes important. the

Then, the second rotation shaft 131 parallel to the first rotation shaft 81 is provided, and the operation handle 130 is rotatably provided on the second rotation shaft 131 . the

According to this configuration, since the operation handle 130 rotates around the second rotation axis 131 , the hand (wrist) holding the operation handle 130 can be less forced to take a forced posture regardless of whether it is pulled or pressed in any direction. In addition, since the second rotation shaft 131 is provided at a predetermined distance d from the first rotation shaft 81, the X-ray irradiation axis Q can be rotated only by rotating the first rotation shaft 81 around the first rotation shaft 81. . Of course, during this rotation operation, since the operation handle 130 rotates around the first rotation shaft 81 , it is not necessary to change the holding posture of the operation handle 130 during the rotation operation. the

Another significant feature of the X-ray imaging apparatus 1 of this embodiment is that the operation handle 130 is provided with a lock release switch 132 for releasing the locked state of the plurality of lock mechanisms. the

That is, in the prior art, the lock release switches 132 are dispersedly provided on both sides of the front surface of the operation panel 110, and the circular base handle 120 is located in the vicinity thereof. Therefore, in this conventional example, while holding the both sides of the basic handle 120 with both hands, it is an operation posture which operates the desired lock release switch 132 and moves it. the

Then, the present inventors devised a structure in which the lock release switch 132 is provided on the operating handle 130 that rotates around the second rotating shaft 131 . According to this configuration, the lock release switch 132 can be operated with one hand while adopting the above-mentioned comfortable holding posture, or the lock release switch 132 can be operated with the other hand while adopting the above-mentioned comfortable holding posture with one hand. . And, in this embodiment, since the second rotating shaft 131 is provided on the annular grip portion 121 of the basic handle 120, it is possible to choose a comfortable and reliable operation while using the basic handle 120 and the operating handle 130 separately. . the

In summary, according to this embodiment, the following ceiling-suspended X-ray imaging device 1 is realized, that is, regardless of the operator's respective physique, the hand reaches the operating handle 130, that is, with a small force, comfortable The posture also allows the heavy bulb to move up, down, left, and right, and rotate freely, and it can be fixed at a desired position even with one-handed operation. the

Hereinafter, the X-ray imaging device 1 of this embodiment will be further described with reference to FIGS. 2 to 7 . the

In the lock mechanism section, the control device 5 performs these operation controls. In addition, a plurality of switches are provided on the lock release switch 132, and the above-mentioned lock release switch is allocated to these switches. Furthermore, in the middle of the lock release switch 132, a free lock release switch 133 for releasing the locked state of all the above-mentioned lock mechanism parts is provided. the

When the X-ray imaging device 1 is powered on, the control device 5 monitors the operation state of the lock release switch 132 in accordance with the operation flow shown in FIG. 2 . That is, in steps 201, 203, 205, 207, and 209, it is monitored whether the lock release switch 132 assigned to the X-axis mechanism section 10 has been operated, whether the lock release switch 132 assigned to the Y-axis mechanism section 20 has been operated, and whether the lock release switch 132 assigned to the Y-axis mechanism section 20 has been operated. Whether the lock release switch 132 assigned to the Z-axis mechanism unit 40 is operated, whether the lock release switch 132 assigned to the swivel mechanism unit 60 is operated, or whether the lock release switch 132 assigned to the rotation mechanism unit 80 is operated. Then, when these unlocking switches 132 are operated, the locked state of the locking mechanism portion corresponding to the operated unlocking switch 132 is released (step 213 ). Then, the control device 5 monitors whether the operation of the unlock switch 132 has been released (step 215), and if it has been released, the lock mechanism part in the above-mentioned unlocked state is set to the locked state again (step 221), and then transfers to the above-mentioned step 201. . the

On the other hand, the control device 5 also monitors whether the free lock release switch 133 has been operated (step 211 ). Then, when the free lock release switch 133 is operated, the control device 5 releases the locked states of all the above-mentioned lock mechanism parts (step 217 ). Then, the control device 5 monitors whether the operation of the free lock release switch 133 has been released (step 219), if it has been released, all locking mechanism parts are set to the locked state again (step 211), and then transfer to the above-mentioned step 201 . the

Next, the appearance structure of the head 100 will be further described with reference to FIG. 3 . Here, FIG. 3 is an external view of a head part, (a) figure shows a front view, and (b) figure shows a side view. the

In the drawing, as described above, the head 100 is rotatably mounted via the rotation mechanism portion 80 mounted on the front surface of the mounting member 70 . The rotation mechanism part 80 is provided with a horizontal first rotation shaft 81 , and the rear part of the X-ray tube device 101 is attached to the first rotation shaft 81 . On the other hand, an operation panel 110 that is thinner in the depth direction is attached to the front surface of the X-ray tube device 101 , and an annular base handle 120 is attached via a plurality of support arms 122 so as to surround the operation panel 110 . In addition, an X-ray moving aperture 102 is provided on the peripheral side of the X-ray tube device 101 so that the X-ray irradiation axis Q is oriented in a direction perpendicular to the first rotation axis 81 . the

The operation panel 110 is provided with an unillustrated control substrate including the control device 5 and the storage device 6 inside, and is provided with a display device 111 and an aperture light switch 112 on its front surface. It controls and displays various operation screens, and has a touch panel that can perform input operations by touch operations. In addition, a diaphragm operation switch 103 is provided on the front surface of the X-ray moving diaphragm 102 . the

In addition, in this embodiment, an operation handle rotatably attached via a second rotation shaft 131 is provided on the grip portion 121 of the base handle 120 at a position in front of the front end portion of the X-ray moving aperture 102. 130. Thereby, the operator can be made to recognize that the attachment position of the operation handle 130 is the front-end|tip part of the X-ray moving aperture 102. FIG. Furthermore, since the second rotation shaft 131 and the first rotation shaft 81 parallel thereto are spaced apart by a predetermined distance d, the front end of the movable diaphragm 102 can be rotated with the predetermined distance d as a radius of rotation. the

In addition, in this embodiment, an operation handle 130 that can be held and operated with one hand regardless of whether it is a right-handed person or a left-handed person is employed. This is further explained with reference to FIGS. 4 to 6 . Here, Fig. 4 is an external view of the operating handle, (a) is a front view, (b) is a bottom view, (c) is a rear view, (d) is a top view, and (e) is a right view , (f) Figure represents the central cross-sectional view. Fig. 5 is an explanatory view of the operation of the operating handle, (a) is an explanatory view showing a holding posture with one hand, and (b) and (c) are explanatory views of the holding action. Fig. 6 is an operation explanatory view of the operating handle. the

In FIG. 4 , the operating handle 130 of this embodiment has a flat appearance shape in which the height dimension is greater than the depth dimension, and the lateral width dimension is greater than the height dimension. And, the shape of the center of the front is formed into a mountain shape with the apex 135 slightly above. That is, the lower part of the apex 135 protruding forward is formed as a wide inclined surface 136 with a certain height, and the upper part is formed as an inclined surface 137 with a slightly smaller height. On both sides of the mountain-shaped shape formed by these two inclined surfaces 136 and 137, a left-right symmetrical switch arrangement surface 138 is formed in which the apex 135 gradually expands in the shape of a hem on both sides. In addition, on the switch arrangement surface 138 having a bilaterally symmetrical shape, the lock release switches 132 are arranged in a line slightly shifted up and down. the

The back side of the operating handle 130 is formed in a concave shape with an edge portion 139 left around, and a mounting portion 140 for the second rotating shaft 131 is provided at a position opposite to the center position of the wide inclined surface 136 . A free lock release switch 133 is adjacent to the ground above. the

As shown in FIG. 5( a ), according to this embodiment, it is possible to hold the edge with the palm of the hand pressed against the above-mentioned wide inclined surface 136 and fingers other than the thumb surrounding the back side from the narrow inclined surface 137 139, thereby holding the operating handle 130 with one hand. In such a holding posture, the force to pull up or push down the operation handle 130 can be transmitted from the palm of the hand via the wide inclined surface 136 . On the other hand, since the force to pull downward is caught and held by fingers other than the thumb, the force can be transmitted. the

In addition, the one hand holding the two inclined surfaces 136 and 137 can reduce the force of shifting (sliding) to both sides (left and right) by using the switch arrangement surface 138 extending in a pendulous shape on both sides (left and right). the

In addition, as shown in FIG. 5(b), when the two inclined surfaces 136, 137 are held with one hand and moved to the left and right, if the operating handle 130 is fixed, the wrist will be burdened, but in this implementation In an example, as shown in (c) figure, since the operation handle 130 rotates, the said problem can be alleviated. the

In addition, as shown in FIG. 6( a ), in this embodiment, since the free lock release switch 133 is provided on the back side, the free lock release switch 133 can be operated by fingers other than the thumb. In addition, in this embodiment, the lock release switches 132 other than the free lock release switch 133 are respectively arranged on the left and right switch arrangement surfaces 138 . Therefore, the lock release switches 132 equally arranged on the left and right sides can be operated with the thumb. the

In addition, in this embodiment, as shown in FIG. 6( b ), even a posture of holding the left and right switch arrangement surfaces 138 with both hands can be handled. At this time, it is only necessary to press the switch arrangement surface 138 with the thumb or operate the lock release switch 132, hold it by the edge portion 139 with other fingers, or operate the free lock release switch 133 with the index finger. the

Furthermore, in this embodiment, although a set of unlocking switches 132 are respectively provided on the switch arrangement surfaces 138 on both sides, they may be arranged on one side. the

Next, a method of setting the position of the X-ray irradiation axis Q of the X-ray imaging device 1 of this embodiment will be described with reference to FIGS. 1 and 7 . Fig. 7 is an explanatory diagram of the operation of the X-ray imaging device. According to this embodiment, the head 100 cannot be moved unless the lock release switch 132 is operated. However, the operation handle 130 can freely rotate via the second rotation shaft 131 . the

In addition, FIG.7 (a) figure and (b) figure demonstrated the case where the head 100 was moved up and down. In the diagram (a), the X-ray irradiation axis Q faces downward. From this state, by operating the lock release switch 132 for unlocking the Z-axis mechanism 40 while holding the operation handle 130 with the front hand, the head 100 can be moved vertically as it is. During this vertical movement, when the operating handle 130 is at a low position, as shown in (d) , if the operating handle 130 is reversed by 180 degrees, a comfortable posture of pressing down can be adopted. the

Also, when moving to the left and right from the state shown in (a), operating the lock release switch 132 for unlocking the X-axis mechanism unit 10 enables the head 100 to move to the left and right in the original posture. At this time, as shown in (c), since the operation handle 130 is rotatable, it can be performed in a posture of pulling to the left and right. the

In addition, when the X-ray irradiation axis Q is rotated from the state shown in (a), the head 100 can be rotated by operating the lock release switch 132 for unlocking the rotation mechanism unit 80 . At this time, as shown in (d), since the operation handle 130 is rotatable, it can be easily rotated. the

In addition, when it is desired to move the head 100 in the front-rear direction from the state in (a), as shown in (e), if the lock release switch 132 for unlocking the Y-axis mechanism unit 20 is operated, the The head 100 moves to the left and right in the original posture. the

Furthermore, in this embodiment, since the basic handle 120 and the operating handle 130 can be used together, it is possible to move the head 100 while holding the operating handle 130 with one hand and holding the basic handle 120 with the other hand. the

In this way, according to the X-ray imaging apparatus 1 of this embodiment, since the head 100 can be moved while operating it with one hand, it is possible to take care of the patient with the other hand. Especially in this embodiment, since the operating handle 130 is arranged near the irradiation port of the X-ray irradiation axis Q, the operating handle 130 can be operated with one hand, and the operator's hand can be moved on the bed 4 with the other hand. The moving operation is performed between the line of sight close to the patient and the X-ray moving aperture 102 . the
