Description

  The present disclosure relates to ophthalmic devices.

  In the field of ophthalmology, in recent years, it has been proposed to diversify the position of the examiner with respect to the ophthalmic apparatus in order to install the ophthalmic apparatus with a layout suitable for each facility.

  For example, Patent Literature 1 discloses a mechanism for turning a touch panel monitor installed in an optometry unit in an arbitrary direction. Thus, the screen of the touch panel monitor can be turned in accordance with the position of the examiner, so that the examiner can operate at the desired position through the touch panel monitor to proceed with the examination.

  Further, in the examination, when the eyelid of the subject is insufficient, the examiner may operate the apparatus while opening the subject with the finger.

JP 2018-646 A

  As a result of the diversification of the examiner's position, the case where the examiner's position is set on the subject side with respect to the ophthalmologic apparatus has been scattered. In this case, since the distance from the examiner to the touch panel monitor is relatively long, the operation becomes difficult.

  Further, in an apparatus as disclosed in Patent Document 1, since the touch panel monitor to which the operation of the examiner is input is placed at a position distant from the subject's eye, the user operates the touch panel monitor while opening the subject's eyelids. Can be a troublesome task for the examiner.

  The present disclosure has been made to solve at least one of the problems of the related art in view of the problems of the related art, and has an object to improve the operability of the device.

  In order to solve the above problem, an ophthalmologic apparatus according to a first aspect of the present disclosure includes an optometry unit for examining an eye to be inspected, and a chin rest on which a face of a subject is placed, A face support unit that supports the face of the subject so that the subject's eye faces the part, and a subject-side housing surface of the optometry unit, or the subject side more than the face, An operation unit fixed to an exposed portion that is exposed even when the subject's face is supported by the support unit, and to which an operation performed by the examiner is input.

  According to the present disclosure, at least one of the problems of the related art is solved, and the operability of the device is improved.

FIG. 2 is a diagram illustrating an example of an overall configuration of an ophthalmologic apparatus. FIG. 2 is an enlarged view illustrating a detailed configuration around an examination window of the ophthalmologic apparatus according to the first embodiment. 5 is a flowchart illustrating an operation of the ophthalmologic apparatus according to the first embodiment. It is a figure for explaining an operation part in a 2nd embodiment. It is the enlarged view which showed the attachment unit which concerns on a modification. It is the enlarged view which showed the attachment unit which concerns on the modification in a mounted state, and the inspection window periphery of an ophthalmologic apparatus.

  An embodiment of an ophthalmologic apparatus according to the present disclosure will be described with reference to the drawings. The items classified by <> below can be used independently or in association. Hereinafter, an embodiment of an ophthalmologic apparatus will be described.

  As an example, the ophthalmologic apparatus 1 shown in FIG. 1 is an apparatus for examining an eye to be examined. In the present embodiment, the measurement and imaging of the subject's eye are collectively referred to as an examination. In the following description, it is assumed that the ophthalmologic apparatus 1 is a non-contact type inspection apparatus unless otherwise specified. However, the present invention is not necessarily limited to this, and the ophthalmologic apparatus 1 may be a contact-type inspection apparatus. In a non-contact type inspection device, for example, any of light, compressed fluid (compressed air), and ultrasonic waves may be used for inspection.

  Specific examples of the ophthalmologic apparatus 1 include an eye refractive power measuring device, a corneal curvature measuring device, a corneal shape measuring device, an intraocular pressure measuring device, an ocular axial length measuring device, a fundus camera, an OCT (optical coherence tomography), and an SLO (scanning laser). Ophthalmoscope), a perimeter, and the like. Any of these may be applied to the ophthalmologic apparatus 1.

<Schematic configuration>
As shown in FIG. 1, the ophthalmologic apparatus 1 includes at least an optometry unit 2, a face support unit 10, and an operation unit 20.

  Further, the ophthalmologic apparatus 1 may additionally include the control unit 70, the base 6, the driving unit 4, and the touch panel monitor 8.

  Further, the ophthalmologic apparatus 1 may include an anterior segment photographing unit and a face photographing unit (neither is shown). The anterior eye imaging unit captures an anterior eye image of the subject's eye. The anterior segment imaging unit may be housed in the optometry unit. The face photographing unit photographs, for example, a face including at least one of the left and right eyes. The anterior segment photographing unit and the face photographing unit are used for automatic alignment between the subject's eye E and the optometric unit 2.

  Further, the ophthalmologic apparatus 1 may include a fixation target projecting unit (not shown). The fixation target projection unit projects the fixation target onto the eye to be examined. The fixation target projection unit may be a so-called internal fixation target (internal fixation lamp) or an external fixation target (external fixation lamp). In the case of an internal fixation target, it may be built in the optometry unit 2. The fixation target projection unit may be capable of changing the presentation position of the fixation target.

<Optometrist>
The optometry unit 2 performs measurement, imaging, and the like of the eye E to be examined. In FIG. 1, as an example, an inspection window 2 a is arranged on the subject-side housing surface of the optometry unit 2. The optometry unit 2 examines the eye E while the eye E faces the examination window 2a. Light, compressed fluid (compressed air), ultrasonic waves, or the like output from the optometry unit 2 for use in the examination is at least emitted to the eye to be examined through the examination window 2a. In FIG. 1, the inspection window 2a is disposed so as to protrude from the surrounding housing surface. In the following description, of the housing surface on the subject side in the optometry unit 2, a portion that protrudes from the surrounding housing surface and that holds the inspection window 2 a is referred to as a lens barrel (or a distal end). It may be called. In the case of a contact type inspection device, the inspection window 2a is replaced with a probe.

<Drive unit>
The driving unit 4 adjusts the positional relationship between the optometry unit 2 and the subject's eye E at least in the front-back direction. The drive unit 4 may further adjust the positional relationship between the optometry unit 2 and the subject's eye E in the vertical and horizontal directions. That is, the positional relationship between the optometry unit 2 and the subject's eye E may be adjusted in the three-dimensional direction. The drive unit 4 supports the photographing unit on the base 6 by being disposed between the base 6 and the photographing unit. The drive unit 4 may be a mechanical mechanism that moves the imaging unit according to the force applied by the examiner. Further, the drive unit 4 may include an actuator (not shown) for moving the photographing unit according to the control signal.

  In addition, the ophthalmologic apparatus 1 may further include a stopping unit 5 for stopping the movement of the optometric unit 2 by the driving unit 4. The stopping unit 5 may also be used as an actuator of the driving unit 4. Of course, the stopping unit 5 may be separate from the driving unit 4. In this case, various types of braking mechanisms can be used for the stop unit 5.

  In the present embodiment, the optometry unit 2 is moved by the driving unit 4, but the movement is not necessarily limited to this. For example, the positional relationship between the optometry unit 2 and the subject's eye E may be adjusted by moving the subject's eye E side. In this case, for example, a drive unit (not shown) for moving a face support unit 10 described later may be provided in the apparatus main body 1.

<Face support unit>
The face support unit 10 is arranged to face the front of the optometry unit 2. The subject's face is supported so that the subject's eye E faces the optometry unit 2 (specifically, the examination window 2a). The face support unit 10 may be fixed to the base 6. The face support unit 10 may include, for example, both the forehead support 12 and the chin rest 11 (for example, see FIG. 1), or one of them. The subject's face is placed on the chin rest 11. In addition, the chin rest 11 may include a sensor that detects that the face of the subject is placed.

<Operation section>
Various operation instructions from the examiner are input to the operation unit 20. The operation unit may be, for example, a button, a touch panel, a trackball, and other various user interfaces. In FIG. 1, as an example, the optometry unit 2 is fixed to the subject-side housing surface. However, it is not necessarily limited to this, and the position of the operation unit 20 is a position on the subject side of the subject-side casing surface of the optometry unit 2 or the subject-side casing surface of the optometry unit 2. Yes, and may be fixed to an exposed portion that is exposed even when the face of the subject is supported by the face support unit 10. Since the operation unit 20 is located at these positions, the examiner can easily reach the operation unit when the position of the examiner is on the subject side with respect to the apparatus. As a result, workability in the inspection is improved. At this time, as shown in FIG. 1, if the operation unit 20 is located above the chin rest 11, the operability is better. When the screen of the monitor (for example, the touch panel monitor 8) faces the subject, when the examiner's position is on the side of the subject's eye with respect to the ophthalmologic apparatus 1, the user checks the screen while checking the screen. Can be operated.

  As shown in FIG. 1, the operation unit 20 is provided in more detail around the examination window 2 a in the housing surface of the optometry unit 2 on the subject side. In FIG. 1, the inspection window 2a protrudes toward the subject's eye with respect to the surrounding housing surface, so that the protruding portion including the inspection window 2a easily comes into contact with the face of the subject. Therefore, the ophthalmologic apparatus 1 is provided with a detection unit for detecting contact with the optometry unit 2. In FIG. 1, as an example, this detection unit is also used as the operation unit 20.

  Here, an example of the operation unit 20 will be described in more detail with reference to FIG. A detection area for detecting a contact is formed at the tip of the apparatus main body 1. As shown in FIG. 1, the detection region may be formed by, for example, a conductive member 21 disposed at a distal end portion. It is formed in a ring shape on the outer periphery of the inspection window 2a. In the present disclosure, the various conductive members may be, for example, metal or conductive resin. A member made of another material may be used. Furthermore, the detection unit (the operation unit 20) may include a detection circuit 22 that detects a change in resistance or capacitance when the examiner and the subject contact the conductive member 21. 2, the electrode 22a of the detection circuit 22 is disposed with an insulator interposed between the electrode 22a and the conductive member 21. The detection circuit 22 detects a change in capacitance via the electrode 22a. Note that the detection unit is not necessarily limited to the above configuration. For example, various sensors such as a micro switch and a photo switch may be used for the detection unit.

  In the example of FIG. 2, the detection area also extends to a plane intersecting with the front of the inspection window (that is, the side surface). Since the finger touches the inspection window, the inspection window is prevented from being stained with the fingerprint.

<Touch panel monitor>
The touch panel monitor 8 also serves as a display unit and a user interface (the “second operation unit” in the present embodiment). As a display unit, the touch panel monitor 8 includes, for example, at least one of an inspection result, information on an alignment state, information on an inspection condition, an image of an eye to be inspected, a face image of an examinee, guide information for proceeding with the inspection, and the like. Is displayed as appropriate. The image of the subject's eye may be an image taken via the optometry unit 2 or via the anterior segment imaging unit, and the face image of the subject is taken via the face imaging unit. It may be an image.

  Further, as a user interface, the touch panel monitor 8 is used to input various operations related to the start of measurement or photographing, the start of an adjustment operation, and the like.

  The touch panel monitor 8 is arranged on the upper surface, the side surface, or the rear surface of the optometry unit 2. Preferably, the touch panel monitor 8 may be disposed on the upper surface or side surface of the optometry unit 2 with the screen facing the subject. However, in this case, the orientation of the screen of the touch panel monitor 8 need not always be constant. As an example, as shown in FIG. 1, the ophthalmologic apparatus 1 switches the screen of the touch panel monitor 8 between a first position facing the subject and a second position different from the first position. May be provided.

In FIG. 1, as an example, the display unit and the second operation unit are also used as the touch panel monitor 8. However, the display unit and the second operation unit are not limited to this. It may be separate. In this case, for example, a stationary monitor such as a PC monitor may be used as the display unit. In addition, a joystick, keyboard, mouse, button, or the like may be used as the second operation unit.
<Control unit>
The control unit 70 is a processor that performs various controls of the ophthalmologic apparatus 1. The control unit 70 includes, for example, a CPU (Central Processing Unit), a ROM, a RAM, and the like. For example, the ROM stores an ophthalmologic apparatus control program for controlling the ophthalmologic apparatus, initial values, and the like. For example, the RAM temporarily stores various information.

  The control unit 70 is connected to the optometry unit 2, the driving unit 4, the touch panel monitor 8, the operation unit 20, the chin rest driving unit 12, and the like.

<Operation>
Next, the operation of the apparatus according to the present embodiment will be described with reference to the flowchart in FIG.

<Assumption>
The operation shown in the flowchart is assumed to be started in a state where the face of the subject is fixed to the face support unit 10. For example, when it is detected that the subject's face is placed on the chin rest 11, various operations may be started with the detection signal as a trigger.

  It is preferable that the operation shown in the flowchart be started with the screen of the touch panel monitor 8 facing the subject. For example, the control unit 70 may detect the orientation of the screen of the touch panel monitor 8 and selectively execute the operation shown in the flowchart when it is detected that the subject is facing the subject.

<Restrict start of adjustment operation (lock)>
First, the control unit 70 restricts (locks) the start of the adjustment operation of the optometry unit 2 (S1). Although details will be described later, the start of the adjustment operation is limited until a contact detection signal from the detection unit (operation unit 20) is received.

  It is assumed that the adjustment operation limited by the processing in S1 includes, for example, adjustment of the positional relationship between the subject's eye and the apparatus (that is, alignment adjustment). In this case, the drive of the drive unit 4 may be limited by the control unit 70. However, other adjustment operations other than the alignment adjustment or instead of the alignment adjustment may be limited. For example, other adjustment operations when the optometry unit is OCT include focus adjustment, polarization adjustment, and optical path length adjustment. In the present disclosure, a detailed description of an optical system and the like in OCT will be omitted. For further details of the configuration, refer to, for example, “JP-A-2017-184787” by the present applicant.

  In the period in which the start of the adjustment operation of the optometry unit 2 is restricted by the processing in S1, the instruction to start the adjustment operation via the touch panel monitor 8 is invalidated by the control unit 70.

<Touch operation guide>
When the start of the adjustment operation is restricted by the processing of S1, the control unit 70 outputs guide information from the touch panel monitor 8 (S2). The guide information includes the content that prompts a touch operation on the detection area of the detection unit (the operation unit 20). For example, an image that graphically shows the periphery of the inspection window 2a including the detection area may be displayed, and a message prompting a touch operation may be displayed on the touch panel monitor 8. For example, a message that “the operation starts when the detection area (the conductor around the inspection window) is touched” may be displayed.

<Restriction release (lock release)>
It is determined whether a touch operation on the detection area of the detection unit (the operation unit 20) has been received (S3). If not, the process may return to S2 and output of guide information may be continued. That is, the control unit 70 may continue to output the guide information until receiving the contact detection signal from the detection unit (the operation unit 20) (S3: No).

  When the contact detection signal from the detection unit (operation unit 20) is received (S3: Yes), the restriction (lock) is released (S4). Thereby, various adjustment operations are started. Since a contact detection signal from the detection unit (the operation unit 20) is used as a start trigger of the adjustment operation (also serving as a release trigger of the restriction in the present embodiment), in the present embodiment, before the adjustment operation is performed. Then, the detection unit (operation unit 20) is checked whether it is normal (more specifically, whether there is a failure or not). Therefore, the reliability of the contact detection by the detection unit (the operation unit 20) during the adjustment operation is improved.

<Alignment adjustment>
As the adjustment operation, first, the positional relationship between the eye E and the optometry unit 2 is adjusted (S5). In the present embodiment, the drive unit 4 is controlled based on images captured by each of the face imaging unit and the anterior eye imaging unit. Thus, the optometry unit 2 is moved in the three-dimensional direction with respect to the eye E so that the positional relationship between the eye E and the optometry unit 2 is within a predetermined allowable range.

  If the control unit 70 receives a contact detection signal from the detection unit (the operation unit 20) during such alignment adjustment, contact between the face of the subject and the optometry unit is detected. As a result, the alignment adjustment is stopped. In other words, the movement of the optometry unit 2 is stopped, and the alignment adjustment is temporarily suspended. At this time, the driving of the stop unit 5 may be controlled based on the contact detection signal. In order to release the suspension state, after the contact is no longer detected by the detection unit (the operation unit 20), a predetermined operation on, for example, any of the touch panel monitor 8 and the operation unit 20 may be requested. .

  Here, it has been described that the movement of the optometry unit 2 is stopped when the contact between the face of the subject and the optometry unit is detected during the alignment adjustment period, but is not necessarily limited thereto. Not something. For example, when the contact is detected, the optometry unit 2 may be driven so that the optometry unit 2 is moved away from the subject. The detection of the contact may be notified to the examiner. In this case, for example, information indicating that a contact has occurred may be displayed from the touch panel monitor 8. Further, a sound (warning sound or message) indicating that contact has occurred may be output from a speaker (not shown).

<Other processing>
After completion of the alignment adjustment, various other adjustments are performed by the control unit 70 (S6), and thereafter, measurement or photographing (capture) is performed (S7). The result of the measurement or the photographing may be stored in the memory (S8).

<Summary of First Embodiment>
As described above, in the first embodiment, the operation unit 20 operated to start the adjustment operation of the optometry unit 2 is disposed closer to the subject than the touch panel monitor 8. Thereby, when the examiner's position is on the subject's side with respect to the apparatus, the examiner's hand can easily reach the operation unit 20. Further, since the touch panel monitor 8 can be directed toward the subject's eye, when the examiner's position is on the subject's side with respect to the apparatus, the examiner operates the operation unit while viewing the information displayed on the touch panel monitor 8. 20 can be operated. Thereby, the examiner can enjoy good workability.

  In the first embodiment, a detection unit that detects contact between the face of the subject and the optometry unit is used as the operation unit 20. As a result, the operation for starting the adjustment operation also serves as the failure detection of the detection unit, and proceeds to the adjustment operation in a normal case, so that the contact between the device and the face of the eye to be inspected is more reliably detected during the adjustment operation. Is done.

  In the above description, the operation unit 20 has been operated to be operated to start the adjustment operation of the optometry unit 2; however, the operation unit 20 is not necessarily limited to this. For example, an operation for starting an examination (measurement or imaging) by the optometry unit 2 may be input via the operation unit 20.

<Second embodiment>
Next, a second embodiment will be described. Also in the second embodiment, the operation unit is provided on the subject side (more specifically, on the front housing surface of the optometry unit 2 or on the subject side) than the touch panel monitor 8. . However, the specific position where the operation unit is provided is different from that of the first embodiment.

  In the second embodiment, as shown in FIG. 4, an operation unit 120 is provided in the face support unit 10. The operation received via the operation unit 120 may be an operation for starting the adjustment operation of the optometry unit, or may be an operation for starting measurement or imaging, as in the first embodiment. It may be an operation for other purposes.

  As shown in FIG. 4, the operation unit 120 is provided in the face support unit 10 in the vicinity of the position where the subject's eye E is arranged with the face supported by the face support unit 10. Here, the vicinity is preferably a range where the left finger of the hand used for opening the eye reaches when the examiner opens the eye to be inspected (≒ the range of approximately “tele palm size”). In this case, the examiner can simultaneously perform the eyelid opening and the operation of the operation unit 120 with one hand. In addition, it is possible to reduce the possibility that the examiner loses his / her gaze from the subject's eye in order to confirm the operation. As an example, in FIG. 4, the operation unit 120 is provided on the forehead pad 12 of the face support unit 10. In addition, since the operation unit 120 is provided on the surface of the forehead rest 12 different from the surface on which the subject's forehead is in contact (the opposite surface in FIG. 4), the finger of the subject reaches the operation unit 120. Cheap.

<Summary of Second Embodiment>
As described above, in the second embodiment, since the operation unit 120 is disposed at a position closer to the subject than the subject-side housing surface of the optometry unit 2, the operation on the operation unit 120 can be opened. At the same time easy to do. The good workability enjoyed in the second embodiment does not necessarily depend on whether the examiner's position is on the subject side with respect to the apparatus. In addition, if the operation unit 20 in the first embodiment is sufficiently close to the eye to be inspected, it is possible to enjoy good workability in performing the operation on the operation unit 20 simultaneously with opening the eyelids.

<Modification>
<An operation unit is arranged separately from the detection unit>
For example, in the first embodiment, the operation unit 20 also serves as a detection unit that detects a contact between the face of the subject and the optometry unit 2, but is not necessarily limited to this. The operation unit 20 may be disposed on the housing surface of the optometry unit 2 on the subject side without being used also as the detection unit. In this case, the examiner can enjoy good workability. For example, the operation unit 20 may be formed on a side surface of a lens barrel that holds the inspection window 2a. When the detection region of the detection unit is formed at the distal end of the lens barrel, the operation unit 20 may be arranged closer to the base end of the lens barrel. However, the present invention is not necessarily limited to this, and the operation unit 20 may be arranged at a position above the chin rest 11 on the other housing surface of the subject.

  In this way, or when the operation unit does not double as the detection unit as in the second embodiment, the operation unit starts the adjustment of the optometry unit 2 and the start of the inspection (imaging or measurement). It may be used not only to receive any of them but also to receive, for example, an operation for adjusting the position of the fixation target.

<Removable operation unit>
For example, in each of the above embodiments, the operation unit is fixed to the device in advance. However, the present invention is not necessarily limited to this, and the operation unit may be detachable from the device. In this case, the operation unit is located at a predetermined position in the apparatus and is located above the chin rest 11 and on the subject-side housing surface of the optometry unit 2 or on the subject side. A fixing portion for attaching to a position may be provided. The detachable operation unit may be a remote controller that can operate the device even when it is separated from the device.

<Attachment unit>
In the ophthalmologic apparatus 1 according to the first embodiment, the attachment unit 50 may be detachable from the examination window 2a. For example, when the ophthalmologic apparatus 1 is an ophthalmologic photographing apparatus, the attachment unit 50 may switch the photographing range (one of the depth region and the angle of view) according to attachment and detachment.

  As shown in FIGS. 5 and 6, when the attachment unit 50 is mounted, the operation unit may be hidden by the attachment unit 50, and the examiner may not directly touch the operation unit 20. Therefore, the distal end of the attachment unit 50 may be used as an operation unit (also a part of the detection unit) to receive an operation by the examiner. In addition, using this, contact with the face of the subject may be detected.

  Here, an example of the attachment unit 50 will be described with reference to FIGS. The attachment unit 50 can be inserted and removed between the ophthalmologic apparatus 1 and the eye E. The attachment unit 50 may be detachable (that is, detachable) from the housing surface of the ophthalmologic apparatus 1 on the subject side. In this case, at least one of the attachment unit 50 and the ophthalmologic apparatus 1 may be provided with an attachment mechanism (not shown) used for attachment and detachment. Various mechanisms can be applied to the attachment mechanism. For example, a mechanism using a magnet, a screw mechanism, or another mechanism may be used.

  At the tip of the attachment unit 50, an attachment-side detection area is formed. The detection area is used to detect contact of the subject with the attachment unit 50. In the attachment unit 50 shown in FIGS. 5 and 6, the attachment-side detection region is formed by disposing the second conductive member 52 at the tip.

  Further, in the first embodiment, the attachment unit 50 has an extension. The extension unit extends the main body side detection area to the tip of the attachment unit 50 (in other words, to the attachment side detection area). Thereby, in the first embodiment, even when the attachment unit 50 is inserted between the ophthalmologic apparatus 1 and the eye E, the contact of the apparatus with the face of the subject is detected well. . Further, a touch operation by the examiner can be detected.

  The extension of the attachment unit 50 shown in FIGS. 5 and 6 includes, for example, a second conductive member 52 and a third conductive member 53. 5 and 6, the third conductive member 53 is connected to the second conductive member 52, and is formed to extend to the base end side of the attachment unit 50. In the inserted state, the third conductive member 53 and the first conductive member 21 on the ophthalmologic apparatus side are electrically connected. As a result, the three members of the first conductive member 21 (main body side detection region), the third conductive member 53, and the second conductive member 52 (attachment side detection region) on the ophthalmic device side are electrically connected, and the detection region is It is extended to the tip of the attachment unit 50. That is, a change in resistance or capacitance when the examiner or the subject comes into contact with the second conductive member 52 is detected by the detection circuit 22 provided on the main body side. That is, since the contact detection in the attachment-side detection area is effective, it is possible to detect the contact of the subject and the examiner with the tip of the attachment unit 50.

  When a touch operation on the tip of the attachment unit 50 is a trigger for starting the adjustment operation of the inspection unit 2, it is also confirmed whether or not the attachment unit 50 is properly mounted based on the touch operation. However, a sensor for detecting attachment / detachment of the attachment unit 50 may be provided separately from the detection unit.

<The open / close switch of the lid is also used as the operation unit>
Further, for example, a cover for protecting the examination window 2a of the optometry unit 2 and a mechanism for opening and closing the cover may be provided in the ophthalmologic apparatus 1. In this case, the ophthalmologic apparatus 1 may further include an opening / closing switch for driving the lid opening / closing mechanism, and the opening / closing switch may also serve as the operation unit. For example, the switch may be operated to open the lid, and the adjustment operation in the optometry unit 2 may be started.
