[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0012] <Embodiment> First, the configuration of a medical treatment device according to an embodiment of the present disclosure will be described. In this embodiment, a dental medical treatment device will be described as an example of the medical treatment device.

[0013] 1 is a perspective view showing a schematic configuration of a medical examination apparatus according to an embodiment. As shown in FIG. 1, the medical examination apparatus 1 according to the embodiment is made up of a microscope 100 and a dental examination unit 200.

[0014] As shown in FIG. 1, the dental treatment unit 200 is composed of an instrument table 210 equipped with treatment instruments 213 (213a to 213e), and a treatment table 220 on which a patient to be treated is placed and treatment is performed.

[0015] The instrument table 210 is provided with an instrument holder 212 on the front side of a table 211 rotatably attached to the examination table 220 via an arm. Medical instruments 213 (213a to 213e) consisting of cutting tools such as an air turbine handpiece and a micromotor handpiece, scalers, three-way syringes, vacuum syringes, etc. are detachably attached to the instrument holder 212. A monitor 216 is also attached to the instrument table 210. The monitor 216 may be attached to a treatment stand pole 230, a wall of a room in which the examination table 220 is installed, etc., in addition to the instrument table 210. The number of monitors 216 is not limited to one.

[0016] Although not shown, the medical instrument 213 is connected to a water supply source, an air supply source, and an air suction unit. The medical instrument 213 is driven by the operator operating the foot controller 214 or the touch panel 215.

[0017] As shown in Fig. 1, the examination couch 220 on which a patient rests comprises a seat placed on a base 221 so as to be movable up and down, a tiltable back panel 223 connected to the rear of the seat, and a tiltable headrest 224 connected to the upper end of the back panel 223. The base 221, the back panel 223, and the headrest 224 are driven by drive units such as hydraulic cylinders and electric motors. These drive units are controlled by a unit control unit 210a (see Fig. 3) built into the instrument table 210 or the back panel 223. The unit control unit 210a can control the drive of the examination couch 220 as well as the medical instrument 213.

[0018] The unit control unit 210a controls the height and posture of the examination couch 220 by changing the positions of the base 221, the back panel 223, and the headrest 224 based on the surgeon's operation of the foot controller 214. The examination couch 220 is not limited to a configuration in which the positions of all of the base 221, the back panel 223, and the headrest 224 can be changed, and may be a configuration in which the position of only the base 221 can be changed, or a configuration in which the position of only the back panel 223 can be changed. Therefore, it is sufficient for the unit control unit 210a to be able to control the height or posture of the examination couch 220 based on the operation of the foot controller 214 by the surgeon.

[0019] In addition, a spitting receptacle 225 and a treatment stand pole 230 are attached to the treatment table 220. The treatment stand pole 230 includes a rotatably protruding arm 231 branching from the middle and a support arm 300 at its upper end. An operating light 232 is provided at the end of the arm 231. In addition, a microscope 100 is provided at the end of the support arm 300. In addition, the spitting receptacle 225 includes a water supply tap for supplying water when rinsing the oral cavity, and a saliva basin.

[0020] The microscope 100 is supported by a position-adjustable support arm 300. The support arm 300 is rotatably attached to the upper end of a treatment stand pole 230 attached to the examination table 220. The support arm 300 is a multi-joint arm type in which multiple arms 301 are connected by multiple joints 301a so that each arm can move, and the microscope 100 attached to the tip of the arm 301 can be moved to a desired position.

[0021] Although the support arm 300 has been described as being attached to the treatment stand pole 230 attached to the examination table 220, it may also be attached to a pole extending from the ceiling, wall, or floor, or to a pole attached to a stand other than the examination table 220.

[0022] Microscope 100 will be described below as being configured to use a camera to magnify and observe the inside of a patient's oral cavity, but it may also be configured only with optical components such as lenses (a so-called optical microscope). Fig. 2 is a diagram schematically showing a microscope in accordance with an embodiment. Microscope 100 includes a housing 10 attached to the tip of arm 301, a display 11 detachable from housing 10, a movable part 12 whose position can be changed relative to housing 10, a handle 13 provided on housing 10, and cameras 14L, 14R and a distance measurement sensor 15 attached to movable part 12.

[0023] The housing 10 is connected to an arm 302 extending from a joint 301a provided at the tip of the arm 301. The surgeon grasps a handle 13 provided on the housing 10 and moves the housing 10, thereby moving the microscope 100 to a desired position.

[0024] However, when the microscope 100 is used to observe the inside of a patient's oral cavity at high magnification to precisely observe teeth, if the surgeon tries to fine-tune the field of view by gripping the handle 13, the field of view moves significantly, making fine adjustment impossible. To address this issue, the cameras 14L, 14R are provided on the movable unit 12, whose position can be changed relative to the housing 10. As will be described later, the movable unit 12 is provided with a stepping motor, which allows the position to be changed relative to the housing 10. Therefore, the microscope 100 allows fine adjustment of the field of view by changing the position of the movable unit 12 relative to the housing 10.

[0025] Changing the position of the movable part 12 relative to the housing 10 requires some kind of operation by the surgeon, but if the surgeon operates the touch panel 215 or the like to change the position of the movable part 12 during medical treatment, the risk of contact infection increases. Therefore, in the medical treatment device 1 according to this embodiment, the position of the movable part 12 can be changed using the foot controller 214 when certain conditions are met, as will be described later. Therefore, in the medical treatment device 1 according to this embodiment, the surgeon can fine-tune the field of view to be observed during medical treatment without directly touching the microscope 100, the touch panel 215, or the like with his or her hands, thereby reducing the risk of contact infection.

[0026] The cameras 14L and 14R are stereo cameras and can capture three-dimensional images of the patient's oral cavity. The cameras of the microscope 100 are not limited to stereo cameras, and a single camera may capture three-dimensional images of the patient's oral cavity using principles such as trigonometry and focusing. Furthermore, the cameras of the microscope 100 are not limited to three-dimensional images, and may be configured to be able to switch between three-dimensional images and two-dimensional images, or to be configured to capture only two-dimensional images. The microscope 100 will be described below as having two cameras, cameras 14L and 14R, but it may also have three or more cameras.

[0027] The display 11 displays three-dimensional images captured by the cameras 14L and 14R. When the display 11 is attached to the housing 10, it functions as an eyepiece of the microscope 100, but when it is removed from the housing 10, it functions as a goggle-type device (head-mounted display (HMD)) that can be worn on the head of the surgeon. The display 11 may also be a device such as a glasses-type head-up display (HUD).

[0028] The distance measurement sensor 15 is a sensor that measures the distance between the patient placed on the examination table 220 and the microscope 100. The distance measurement sensor 15 is, for example, a laser distance measurement sensor having a light-emitting element that irradiates the patient with laser light and a light-receiving element that receives the laser light reflected by the patient. The distance measurement sensor 15 is not limited to a laser distance measurement sensor, and may also be an ultrasonic distance measurement sensor or a microwave distance measurement sensor. Note that the distance measurement sensor 15 is just one example and may be any distance measurement means that has the function of measuring the distance between the patient and the microscope 100. For example, the distance between the patient and the microscope 100 may be measured using a stereo camera, the distance between the patient and the microscope 100 may be determined from the angle of the arm 301, or the distance between the patient and the microscope 100 may be determined from the angle of the arm 301, the position of the base 221, and the position of the back panel sheet 223.

[0029] Next, we will explain the control of the microscope 100 by the medical examination device 1. Figure 3 is a block diagram showing the configuration of the medical examination device 1 in this embodiment. As shown in Figure 3, the microscope 100 has an image processing unit 12a that processes images captured by the cameras 14L and 14R, a camera control unit 12b that controls the inter-camera distance between the cameras 14L and 14R and the angle of each camera, and a stepping motor 12c that changes the positions of the cameras 14L and 14R.

[0030] Furthermore, the microscope 100 has a stage control unit 10a for controlling the position of the movable unit 12, a stepping motor 10b for changing the position of the movable unit 12 in the X-axis direction, a stepping motor 10c for changing the position in the Y-axis direction, a stepping motor 10d for changing the position in the Z-axis direction, and a stepping motor 10e for changing the position in the θ-axis direction. The microscope 100 also has a display 11 and a distance measurement sensor 15.

[0031] The image processing unit 12a, the camera control unit 12b, and the stage control unit 10a are connected to the unit control unit 210a of the dental treatment unit 200 using CAN (Controller Area Network) communication. Therefore, the unit control unit 210a transmits control signals to the image processing unit 12a, the camera control unit 12b, and the stage control unit 10a based on an operation signal from the user operation unit 250. Specifically, when the image processing unit 12a receives a control signal requesting an image from the unit control unit 210a, it outputs images captured by the cameras 14L and 14R to the display 11. Furthermore, when the image processing unit 12a receives a control signal requesting zooming (ZOOM) from the unit control unit 210a, it outputs a ZOOM request to the cameras 14L and 14R. In response to the ZOOM request, the cameras 14L and 14R transmit enlarged images to the image processing unit 12a.

[0032] The camera control unit 12b drives the stepping motor 12c and changes the positions of the cameras 14L and 14R based on a control signal from the unit control unit 210a. The camera control unit 12b changes the positions of the cameras 14L and 14R and adjusts them so that appropriate three-dimensional images can be captured as a stereo camera. The stage control unit 10a drives the stepping motors 10b to 10e and changes the position of the movable unit 12 based on a control signal from the unit control unit 210a. By changing the position of the movable unit 12, the image processing unit 12a can move the field of view to be observed and obtain a three-dimensional image of the patient's oral cavity at a desired position.

[0033] In addition to the unit controller 210a, the dental treatment unit 200 also includes a monitor 216, a user operation unit 250, and an opto-light controller 15a. The monitor 216 is configured with a flat panel display such as an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence) display. The monitor 216 is also capable of switching between two-dimensional image display and three-dimensional image display based on image data transmitted from the image processor 12a. Of course, the dental treatment unit 200 may be provided with two separate monitors, a three-dimensional image display monitor 216a and a two-dimensional image display monitor 216b.

[0034] The user operation unit 250 includes, for example, a foot controller 214, a touch panel 215, and the like. The foot controller 214 accepts operations for driving the examination table 220 and the examination instrument 213 by foot operation by the surgeon or the like, and also accepts operations for driving the microscope 100, which will be described later. The foot controller 214 is connected to the unit control unit 210a via a foot controller control unit 214A. The foot controller control unit 214A generates an operation signal based on the surgeon's foot operation using the foot controller 214, and transmits the operation signal to the unit control unit 210a.

[0035] The touch panel 215 is provided on a display unit provided on the instrument table 210, and receives operations for driving the examination table 220 and the medical instrument 213 by touching button images displayed on the display unit. The touch panel 215 is connected to the unit controller 210a via a touch panel controller 215a. The touch panel controller 215a generates an operation signal based on the operator's touch operation on the touch panel 215, and transmits the operation signal to the unit controller 210a.

[0036] The operation light control unit 15a transmits data on the distance between the patient and the microscope 100 placed on the examination table 220 to the unit control unit 210a based on the output signal from the distance measurement sensor 15. The operation light control unit 15a also turns on or off the operation light 232 shown in FIG. 1 according to the distance measured by the distance measurement sensor 15.

[0037] The unit control unit 210a includes a central processing unit (CPU), random access memory (RAM), and read-only memory (ROM). The CPU executes operating programs stored in the ROM or the like to comprehensively control the entire medical device 1. The ROM stores programs executed by the CPU and other data. The RAM serves as a working area for the CPU when it executes programs, temporarily storing programs and data required for program execution. The foot controller control unit 214A, touch panel control unit 215a, and operation light control unit 15a may be implemented as a single function of the CPU of the unit control unit 210a. Of course, the foot controller control unit 214A, touch panel control unit 215a, and operation light control unit 15a may be configured by at least one semiconductor integrated circuit such as a processor, at least one application-specific integrated circuit (ASIC), at least one digital signal processor (DSP), at least one field programmable gate array (FPGA), and / or other circuits having a computing function.

[0038] Furthermore, the image processing unit 12a, the camera control unit 12b, and the stage control unit 10a are configured by at least one semiconductor integrated circuit such as a processor, at least one application specific integrated circuit (ASIC), at least one DSP, at least one FPGA, and / or other circuits having a computing function. Of course, the image processing unit 12a, the camera control unit 12b, and the stage control unit 10a may be realized as one function of the CPU of the unit control unit 210a.

[0039] [Switching Operation Modes] Next, switching of the operation mode of the foot controller 214 will be described using a flowchart. FIG. 4 is a flowchart for explaining switching of the operation mode of the medical examination apparatus 1 in this embodiment. First, the unit control unit 210a determines whether or not operation of the operation mode switching button on the touch panel 215 has been accepted (step S101). Specifically, the touch panel 215 has a switching button for switching between a first operation mode in which the foot controller 214 is used to normally operate the examination table 220 and a second operation mode in which the foot controller 214 is used to operate the microscope 100. Note that the switching button is just an example, and any switching means having the function of switching the operation mode is not limited to a switching button. Furthermore, if it can be determined from the position of the back panel sheet 223 that the patient is receiving treatment in an upright position, the unit control unit 210a may restrict operation of the switching button to prevent erroneous switching to the second operation mode.

[0040] If the operation of the switching button has not been received (NO in step S101), the unit control section 210a determines whether the distance between the microscope 100 and the patient measured by the distance measurement sensor 15 is equal to or less than a predetermined distance (for example, 30 cm) (step S102). Specifically, when the distance between the microscope 100 and the patient is equal to or less than the predetermined distance, the operator grasps the handle 13 to move the microscope 100, and sets it so that the inside of the patient's oral cavity can be magnified and observed with the microscope 100.

[0041] If the distance between the microscope 100 and the patient is longer than a predetermined distance (NO in step S102), the unit control unit 210a determines whether the examination couch 220 is being driven in slow mode (step S103). Specifically, the control of the examination couch 220 includes a normal mode in which the base 221, back panel 223, and headrest 224 are moved at a normal speed (first speed) when no patient is on the examination couch 220, and a slow mode in which the base 221, back panel 223, and headrest 224 are moved at a speed (second speed) slower than the normal speed when a patient is on the examination couch 220. Therefore, when the examination couch 220 is being driven in slow mode, it means that treatment is in progress, and there is a possibility that the inside of the patient's oral cavity is being magnified and observed with the microscope 100.

[0042] If the examination table 220 is not being controlled in slow mode (NO in step S103), the unit control section 210a sets the operation mode to be set in the foot controller 214 to a first operation mode in which operations of the examination table 220 are assigned to multiple operation units. FIG. 5 is a diagram for explaining the operation assignment in the first operation mode of the foot controller 214 in this embodiment. The foot controller 214 has seven operation units: one button, four levers, and two pedals. In the first operation mode, the following operations are assigned to each of the seven operation units.

[0043] As shown in Fig. 5, the center button of the foot controller 214 is assigned as a handpiece water injection switch 214a, the right-side forward / backward lever is assigned as a switch lever 214b for switching between the micromotor and ultrasonic scaler modes, and the right-side up / down lever is assigned as a switch lever 214c for switching the operable ON / OFF. Furthermore, the right-side pedal of the foot controller 214 is assigned as a micromotor handpiece pedal 214d for changing the rotation speed of the micromotor, and the left-side pedal is assigned as an air turbine handpiece pedal 214e for changing the rotation speed of the air turbine. The left-side up / down lever of the foot controller 214 is assigned as a lift lever 214f ​​for raising and lowering the base 221, and the left-side forward / backward lever is assigned as a lift lever 214g for raising and lowering the back panel 223. Note that the operations assigned to each operating unit in the first operating mode shown in Fig. 5 are merely examples, and the user can freely assign operations to each operating unit.

[0044] In the first operation mode, the foot controller 214 only assigns to the multiple operation units the operation of the examination table 220 and the operation of the medical instrument 213, but does not assign the operation of the microscope 100. In other words, if the unit control unit 210a determines that none of the conditions from step S101 to step S103 are met (NO in all steps S101 to S103), it determines that the surgeon will not use the microscope 100 and does not assign the operation of the microscope 100 to the operation units of the foot controller 214.

[0045] On the other hand, if any one of the conditions from step S101 to step S103 is satisfied (YES in any one of steps S101 to S103), the unit control section 210a sets the second operation mode in which operations of the microscope 100 are assigned to multiple operation sections as the operation mode to be set in the foot controller 214. Fig. 6 is a diagram for explaining the operation assignment in the second operation mode of the foot controller 214 in this embodiment. In the second operation mode, the following operations are assigned to each of the seven operation sections.

[0046] As shown in Fig. 6, the button in the middle of the foot controller 214 is assigned as a cross key 214x (D-pad) for moving the movable part 12 of the microscope 100, and the up / down lever on the right side is assigned as a light intensity adjustment lever 214y for adjusting the light intensity of the microscope 100. Furthermore, the up / down lever on the left side of the foot controller 214 is assigned as a zoom switch 214z for zooming in and out of the microscope 100, and the forward / backward lever on the left side is assigned as a focus adjustment lever 214w for adjusting the focus of the microscope 100. Note that the operations of the microscope 100 assigned to each operation unit in the second operation mode shown in Fig. 6 are just an example, and the user can arbitrarily set the operations of the microscope 100 to be assigned to each operation unit.

[0047] In the foot controller 214 set to the second operation mode shown in Fig. 6, the operation units assigned to operate the medical instrument 213 are assigned the same operations as in the first operation mode. That is, even in the second operation mode, the right-side forward / backward lever of the foot controller 214 is assigned as a switching lever 214b that switches between the micromotor and ultrasonic scaler modes. Furthermore, even in the second operation mode, the right-side pedal of the foot controller 214 is assigned as a micromotor handpiece pedal 214d that changes the rotation speed of the micromotor, and the left-side pedal is assigned as an air turbine handpiece pedal 214e that changes the rotation speed of the air turbine. In the foot controller 214 shown in Fig. 6, only the operation units indicated by hatching are assigned to operate the microscope 100. Therefore, regardless of the change in operation mode, the surgeon can operate the medical instrument 213 by using the same foot operation on the foot controller 214, preventing operational errors.

[0048] When operations related to the medical instrument 213 are assigned to some of the multiple operation units (for example, the switching lever 214b, the micromotor handpiece pedal 214d, and the air turbine handpiece pedal 214e) in the first operation mode, the unit control unit 210a assigns operations related to the microscope 100 to some or all of the multiple operation units other than the operation units assigned with operations related to the medical instrument 213 in the second operation mode. This prevents the surgeon from mistakenly operating the operation related to the medical instrument 213 even when the operation mode of the medical device 1 is changed, allowing the surgeon to safely treat the patient.

[0049] In the flowchart shown in FIG. 4, it has been explained that when any one of the conditions from step S101 to step S103 is satisfied (YES in any one of steps S101 to S103), the unit control section 210a sets the operation mode to be set in the foot controller 214 to the second operation mode. However, the unit control section 210a may perform processing to determine whether any one of the conditions from step S101 to step S103 is satisfied. Furthermore, the unit control section 210a may set the operation mode to be set in the foot controller 214 to the second operation mode when multiple conditions from step S101 to step S103 are satisfied. Furthermore, the conditions from step S101 to step S103 are merely examples, and the unit control section 210a may set the operation mode to be set in the foot controller 214 to the second operation mode based on other conditions.

[0050] Next, unit control section 210a determines whether a stop operation has been received (step S106). If a stop operation has not been received (NO in step S106), unit control section 210a returns the process to step S101. On the other hand, if a stop operation has been received (YES in step S106), unit control section 210a ends the operation mode switching process.

[0051] The processing described above can also be explained as follows as a control method for the medical examination device 1. The control method for the medical examination device 1 includes the steps of: setting a first operation mode in which operation of the examination table 220 is assigned to a plurality of operation units as an operation mode that can be set on the foot controller 214 (step S104); determining whether or not a predetermined condition is met (steps S101 to S103); and, if it is determined that the predetermined condition is met, switching the setting of the foot controller 214 from the first operation mode to a second operation mode in which operation of the microscope 100 is assigned to some of the plurality of operation units (step S105).

[0052] The control method of the medical examination device 1 can also be explained as processing of a program executed by the unit control unit 210a of the medical examination device 1. The program executed by the unit control unit 210a of the medical examination device 1 includes the steps of: setting a first operation mode in which operation of the examination table 220 is assigned to a plurality of operation units as an operation mode that can be set on the foot controller 214 (step S104); determining whether or not a predetermined condition is met (steps S101 to S103); and, if it is determined that the predetermined condition is met, switching the setting of the foot controller 214 from the first operation mode to a second operation mode in which operation of the microscope 100 is assigned to some of the plurality of operation units (step S105).

[0053] [Switching displayed images] Next, switching of the display image of the microscope 100 will be described using a flowchart. FIG. 7 is a flowchart for explaining switching of the display image of the medical examination apparatus 1 in the embodiment. First, as a premise, the microscope 100 is equipped with a stereo camera (cameras 14L and 14R) and can capture a 3D image of the patient's oral cavity. However, when viewing a 3D image display on the monitor 216, dedicated 3D glasses are required; without the 3D glasses, the image appears double and is difficult to view. Therefore, the unit control unit 210a switches between outputting a 2D image or a 3D image from the image processing unit 12a depending on the monitor status. When outputting a 2D image, the image processing unit 12a outputs the image from either the camera 14L or 14R.

[0054] When the surgeon is viewing the image displayed by the microscope 100 on the display 11, the image processing unit 12a outputs a three-dimensional image of the patient's oral cavity to the display 11. However, when the patient is shown an image of the oral cavity on the monitor 216 without three-dimensional glasses, the image processing unit 12a outputs a two-dimensional image of the patient's oral cavity to the monitor 216. Furthermore, when outputting an image to the monitor 216a for three-dimensional image display, the image processing unit 12a outputs the three-dimensional image to the monitor 216a, and when outputting an image to the monitor 216b for two-dimensional image display, the image processing unit 12a outputs the two-dimensional image to the monitor 216b.

[0055] 7, a process for switching the displayed image on the display 11 and monitor 216, which are capable of displaying two-dimensional images and three-dimensional images, will be described. First, the unit control unit 210a determines whether or not an operation of a two-dimensional image display switching button on the touch panel 215 has been accepted (step S201). Specifically, the touch panel 215 has a switching button for switching between displaying a two-dimensional image or a three-dimensional image on the microscope 100.

[0056] If operation of the switching button has not been accepted (NO in step S201), the unit control unit 210a causes the image processing unit 12a to output the captured image to the display 11 or the monitor 216 as a 3D image, and displays the 3D image on the display 11 or the monitor 216 (step S202). If operation of the switching button has been accepted (YES in step S201), the unit control unit 210a causes the image processing unit 12a to output the captured image to the display 11 or the monitor 216 as a 2D image, and displays the 2D image on the display 11 or the monitor 216 (step S203).

[0057] Furthermore, the unit control section 210a determines whether or not it has accepted an operation of a display switching button for the operation mode on the touch panel 215 (step S204). Specifically, the touch panel 215 has a switching button for switching whether or not to superimpose information on the operation mode set by the foot controller 214 on the display image of the microscope 100.

[0058] When the operation of the switching button is accepted (YES in step S204), the unit control section 210a superimposes information about the operation mode set by the foot controller 214 on the display image of the microscope 100 (step S205). FIG. 8 is a diagram for explaining a display in which the information about the operation mode is superimposed on the display image. In FIG. 8, a three-dimensional image of the patient's oral cavity is displayed on the display screen of the display 11, and a display screen 11A for the information about the operation mode is superimposed on the right edge. The display screen 11A displays that the operation mode currently set for the foot controller 214 is the "second operation mode," and also displays the operations assigned to the operation section. In the example shown in FIG. 8, the display screen 11A displays that the XY stage operation is assigned to the cross key and that focus adjustment is assigned to the forward / backward lever on the left.

[0059] In this way, by superimposing the information on the operation mode set by the foot controller 214 on the display image of the microscope 100, the surgeon can check the operation mode currently set by the foot controller 214, and can easily understand the operations assigned to the operation unit, thereby preventing erroneous operations. Note that the superimposed display of the information on the operation mode shown in Fig. 8 is one example, and the operations assigned to the image of the foot controller 214 may also be superimposed.

[0060] 7, unit control section 210a determines whether a stop operation has been received (step S206). If a stop operation has not been received (NO in step S206), unit control section 210a returns the process to step S201. On the other hand, if a stop operation has been received (YES in step S206), unit control section 210a ends the display image switching process.

[0061] <Modification> (1) A light may be provided on the microscope 100. If a light is provided on the microscope 100, the unit control unit 210a turns on the light on the microscope 100 and turns off the operator light 232 when the distance between the microscope 100 and the patient measured by the distance measurement sensor 15 is less than a predetermined distance. Conversely, if the distance between the microscope 100 and the patient measured by the distance measurement sensor 15 is longer than a predetermined distance, the unit control unit 210a turns off the light on the microscope 100 and turns on the operator light 232. This allows the surgeon to switch between the light on the microscope 100 and the operator light 232 without having to operate them. Note that if a light is provided on the microscope 100, the light intensity and irradiation field of the light on the microscope 100 may be automatically changed depending on the distance between the microscope 100 and the patient measured by the distance measurement sensor 15.

[0062] (2) Information such as the distal-mesial direction may be superimposed on the display image of the microscope 100. By superimposing the information on the mesial-distal direction on the display image of the microscope 100, the surgeon can easily understand in which direction to move the microscope 100. Note that a sensor (e.g., a potentiometer, a gyro sensor, etc.) that detects the direction of rotation may be incorporated into the microscope 100, and the direction of the display image of the microscope 100 may be rotated based on the detection result of the sensor. Of course, the direction of the display image of the microscope 100 may also be rotated based on the surgeon's foot operation using the foot controller 214.

[0063] (3) Although the conditions for switching the operation mode set in the foot controller 214 to the second operation mode have been described as the conditions in steps S101 to S103, the condition may also be the operation of a touchless sensor provided in the operation light 232. The operation mode of the foot controller 214 may be switched to the second operation mode by the touchless sensor used to switch the operation light 232 on and off.

[0064] (4) In the examination table 220 shown in Figure 1, two arms are provided on the treatment stand pole 230: an arm 231 on which an operation light 232 is attached, and an arm 301 on which a microscope 100 is attached. By providing a light on the microscope 100, the examination table 220 may not be provided with the operation light 232, and the treatment stand pole 230 may be provided with only the arm 301 on which the microscope 100 is attached. Reducing the number of arms to one leads to space savings for the examination table 220, improved operability, and reduced cost.

[0065] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present disclosure is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
