Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical microscope used in the medical field.

[0002]

2. Description of the Related Art In recent years, with the development of surgical methods and surgical tools, so-called microsurgery, which is an operation on a minute affected area, has been frequently performed. In microsurgery, ophthalmology, otolaryngology, neurosurgery,
A surgical microscope for magnifying and observing a surgical site is used, as in examples of orthopedic / plastic surgery. FIG. 9 shows a surgical microscope mainly used in the field of ophthalmology.

One end of a first arm 2a is attached to the upper end of the pedestal 1 so as to be rotatable about an axis A. One end of the second arm 2b is rotatably attached to the other end of the first arm 2a via a shaft B and a shaft C (a shaft perpendicular to the paper surface), and is attached to the free end (the other end) of the second arm 2b. An XY drive device 3 is rotatably attached via an axis D. The mirror body 4 is attached to the XY drive device 3. That is, the XY drive device 3 and the mirror body 4 are movably held by the arms 2a and 2b. The XY drive device 3 is for moving the mirror body 4, and the mirror body 4 can be set at a desired position in the three-dimensional space by its drive and the action of the arms 2a and 2b.

The change of magnification, focus adjustment, movement of the mirror body, etc. of the surgical microscope are carried out by the motors (not shown) built in the mirror body 4 and the XY drive device 3, respectively, and the control thereof is carried out by the gantry. It is performed by a control unit (not shown) built in the unit 1. A foot switch 5 is connected to the control unit, and by operating the foot switch 5, it is possible to change the magnification and focus of the lens body 4, and to move the lens body 4 in a desired direction. .

As shown in FIG. 10, the foot switch 5 is used for enlarging (zooming up) and reducing (zooming down) the magnification.
) And a pair of momentary switches 7a and 7b for focus up and focus down, respectively. Further, a joystick type foot switch (hereinafter abbreviated as joystick) 8 is provided for controlling the XY drive device 3.

The joystick 8 includes two positive direction drive switches (not shown) corresponding to the X-axis direction (front-back direction) and two negative-direction drive switches corresponding to the Y-axis direction (left-right direction) of the XY drive device 3. (Not shown) is built in, and these switches are selectively turned on in response to a lever operation. By operating the joystick 8, it is possible to move the mirror body 4 in a total of 8 directions including front-back, left-right and diagonal.

During surgery, the operating direction of the joystick 8 and the driving direction of the XY drive device 3 are initially aligned in advance so that the operator operates the joystick 8 with his / her foot while looking through the mirror body 4. Then, the mirror body 4 can be moved in a desired direction.

By the way, as a surgical microscope, Japanese Patent Publication No. 62-1
There are those disclosed in Japanese Patent No. 66312 and Japanese Utility Model Publication No. 3-13112. An example of a foot switch is Japanese Patent Laid-Open No. 57-88627.
It is shown in the publication.

In Japanese Patent Publication No. 62-166312, one foot switch is associated with a plurality of operation modes such as magnification change, focus adjustment, and XY movement, and one of these operation modes is selected in response to voice input. The selection is made appropriately. The one in Japanese Utility Model Publication No. Sho 3-13112 has a magnification change, focus adjustment, X
The foot switch is provided with a plurality of operation switches corresponding to various functions such as -Y movement, and the functions of the operation switches can be exchanged by changing wiring connections.
In Japanese Patent Laid-Open No. 57-88627, a plurality of operation switches are provided on the foot switch, and the function of each operation switch is appropriately selected according to key input or voice input.

[0010]

In the above-described surgical microscope, when trying to observe the affected area in detail from various directions, it is not enough to move the body 4 by the XY drive device 3.
It is necessary to move the mirror body 4 together with the XY drive device 3 by the arms 2a and 2b.

However, when the arms 2a and 2b move, a misalignment occurs between the operating direction of the joystick 8 performed before the operation and the driving direction of the XY drive device 3, and the operating direction of the joystick 8 and the mirror body 4 move. The actual direction of movement will not match.

In particular, since the operator usually operates the foot switch 5 while looking into the mirror body 4, it becomes more difficult to grasp the correspondence between the operation and the actual movement. Therefore, each time the foot switch 5 is operated, it is necessary to check the movement of the mirror body 4 and change the position of the foot switch 5, which is very troublesome. It is a heavy physical and mental burden on the operator, and the operation can be prolonged.

In addition, as in Japanese Patent Publication No. 62-166312,
When one of the operation modes is selected by voice input, an error in voice recognition appears as an erroneous operation. In the case of selecting the function of each operation switch of the foot switch by key input or voice input as in Japanese Patent Laid-Open No. 57-88627, display means for displaying the switching state of the function is provided. As the height increases, the surgeon operates the foot switch while checking the display one by one, which results in poor operability.

The present invention takes the above circumstances into consideration,
The purpose is to ensure that the mirror body can be reliably and easily moved to the desired position without checking the movement of the mirror body and changing the position of the operating means even when the observation direction changes in various ways. An object is to provide a movable operating microscope.

[0015]

The surgical microscope of the present invention comprises a mirror body, drive means for moving the mirror body, holding means for movably holding the drive means and the mirror body, and An operating means for designating the driving direction of the mirror body by the driving means, a detecting means for detecting the state of the holding means, and a correcting means for correcting the driving direction of the driving means according to the detection result of the detecting means. Equipped with.

[0016]

When the operating means is operated, the driving means operates and the mirror body moves. At this time, the state of the holding means is detected, and the driving direction of the driving means is corrected according to the detection result.

[0017]

The XY drive unit 13 is for moving the mirror body 14 in a plurality of directions.
With the action of b, the mirror body 14 can be set at a desired position in the three-dimensional space.

The magnification change, focus adjustment, movement of the mirror body, etc. are performed by a motor (not shown) built in the mirror body 14 and the XY drive device 13, respectively, and their control is not shown built in the gantry 11. It is performed by each control unit. A foot switch 15, which is an operating means, is connected to these control units. This foot switch 15
By operating, it is possible to change the magnification of the mirror body 14 and adjust the focus, and to specify the drive direction for the mirror body 14.

The foot switch 15 has the same appearance and function as the conventional foot switch 5 shown in FIG. 10, except that it incorporates a stepping motor 30 which will be described later.
By operating the joystick 8, the mirror body 14 is moved back and forth,
It can be moved left and right and diagonally in a total of 8 directions. FIG. 2 schematically shows the internal structure of the arm 12a near the axis A.

First, the axis A is mounted on the mount 1 together with the arm 12a.
Rotate on 1. A photo interrupter group 21 is provided at a position surrounding the axis A. This photo interrupter group 2
1 includes four photo interrupters 21a, 21b, 21c, and 21d arranged at intervals of 90 degrees.
It is fixed to the side. Each photo interrupter is
Light emitted from a light source (not shown) is detected, and its output signal is sent to a control unit 40 in the gantry 11 which will be described later.

The shading plate 22 is fixed to the axis A. The light blocking plate 22 is formed in a fan shape with an angle of 120 degrees, and functions to selectively block light incident on the photo interrupters 21a, 21b, 21c, and 21d in accordance with the rotation of the axis A, that is, the rotation of the arm 12a. do.

This photo interrupter group 21, the light shielding plate 2
2, and the control unit 40 described later constitutes a detection unit that detects the state (rotational position) of the arm 12a with respect to the gantry 11. Similar detecting means is also provided on the axis B portion and the axis D portion of the arm 12b. The state (rotational position) of the arm 12b with respect to the arm 12a is detected by the detection means of the axis B portion. The state (rotational position) of the XY drive device 13 with respect to the arm 12b is detected by the detection means of the axis D portion.

As shown in FIG. 3, a stepping motor 30 is provided in the foot switch 15, and the joystick 8 is connected to the rotation shaft of the stepping motor 30. That is, the joystick 8 is rotated by the operation of the stepping motor 30. The main part of the control circuit is shown in FIG.

A control unit 40 is provided in the gantry 11, and the photo interrupter groups 21, 22, and 23 are connected to the control unit 40. The photo interrupter group 22 is an arm 12b.
Is provided on the axis B portion of the arm 12b, and the photo interrupter group 23 is provided on the axis D portion of the arm 12b. Control unit 40
Has an arithmetic unit 41 and a motor drive unit 42.

The operation unit 41 is composed of the photo interrupter group 2
The rotation position of the arm 12a with respect to the gantry 11 and the arm 1 with respect to the arm 12a based on the outputs of 1, 22, 23.
2b rotation position, XY drive device 1 for arm 12b
3, a means for detecting the rotational position of the XY drive 3, a means for detecting how much the driving direction of the XY drive device 13 is deviated from the initial position set before the operation based on the detection results, and the detection. And a means for issuing a rotation angle command corresponding to the angle.

The motor drive unit 42 drives the stepping motor 30 so as to rotate the joystick 8 by an angle according to the rotation angle command issued from the calculation unit 41. The rotation of the joystick 8 is performed by the XY drive device 1.
The driving direction of No. 3 is indirectly corrected, and the corresponding shift between the operating direction of the joystick 8 and the driving direction of the XY driving device 13 is eliminated. Reference numeral 50 denotes an XY drive control unit, which drives and controls the XY drive device 13 in accordance with each switch output of the joystick 8. The operation of the above configuration will be described.

Since the photo interrupter groups provided in the shaft A portion, the shaft B portion, and the shaft D portion respectively have the same structure, the shaft A portion will be described here as an example.

As shown in FIG. 2, four photo interrupters 21a, 21 of the photo interrupter group 21 are included.
Of the b, 21c, and 21d, the light-shielding plate 22 always blocks light entering one or two photo interrupters. This light blocking state changes due to the rotation of the axis A and the light blocking plate 22 accompanying the rotation of the arm 12a.

An OFF signal is output from the photo interrupter that is shielded from light, and an ON signal is output from the photo interrupter that is not shielded from light. There are eight combinations of the ON signal and the OFF signal, depending on the relative positional relationship between each photo interrupter and the light shielding plate 22. That is, the rotation position of the arm 12a can be detected by the control unit 40 in eight steps.

Similar signals are output from the photointerrupter groups of the B-axis portion and the D-axis portion, and the rotation position of the arm 12b and the rotation position of the XY drive device 13 are set to 8 respectively.
Can be detected in stages. When using the surgical microscope, the operator initially aligns the operating direction of the joystick 8 and the driving direction of the XY drive device 13 before the surgery.

When the operator rotates any one of the arm 12a, the arm 12b, and the XY drive device 13 in order to observe the observed region from another direction, the rotation position is changed from the output of each photo interrupter group. To be detected. From this detection result, it is 45 how much the driving direction of the XY driving device 13 deviates from the initial position set before the operation.
Detected in degrees.

When an angle deviation is detected, the stepping motor 30 operates by that angle and the joystick 8 rotates. By the rotation of this joystick 8,
The drive direction of the XY drive device 13 is indirectly corrected, and the corresponding shift between the operation direction of the joystick 8 and the drive direction of the XY drive device 13 is eliminated. In other words, if the operator tilts the joystick 8 to the front side of himself, the mirror body 14 will surely move to the front side of the operator.

Therefore, the operator can surely and easily move the mirror body 14 to a desired position while continuing observation without checking the movement of the mirror body 14 one by one and without changing the position of the foot switch 15. You can As a result, the physical fatigue of the operator as well as the patient is reduced, and the mental fatigue of the operator is significantly reduced.

In the above embodiment, the number of photo interrupters provided in each shaft portion is four. However, the number is not limited, and by increasing the number, for example, the operating direction of the joystick 8 and the driving of the XY drive device 13 can be performed. The deviation angle from the direction can be detected and corrected more finely, and the accuracy can be improved. A second embodiment of the present invention will be described.

Here, as shown in FIG.
A signal conversion unit 43 is provided in place of the motor drive unit 42. Further, FIG. 1 does not include the stepping motor 30.
0 foot switch 5 is used, joystick 8
The output of each switch is sent to the XY drive controller 50 through the signal converter 43.

The signal conversion unit 43 has a function of outputting the output of each switch of the joystick 8 in a state in which the position is changed by an amount corresponding to the detection angle of the calculation unit 41. Other configurations are the same as those in the first embodiment. The operation will be described. When using the surgical microscope, the operator must operate the joystick 8 and the XY drive device 13 in advance before the operation.
Initially align with the driving direction of.

When the operator rotates any one of the arm 12a, the arm 12b, and the XY drive device 13 in order to observe the observed region from another direction, the rotation position is determined from the output of each photointerrupter group. To be detected. From this detection result, it is 45 how much the driving direction of the XY driving device 13 deviates from the initial position set before the operation.
Detected in degrees.

When the joystick 8 is operated, a signal corresponding to the operation direction is output from each switch in the joystick 8. At this time, if an angular shift between the initial position and the driving direction of the XY drive device 13 is detected, the switch outputs of the joystick 8 are repositioned by the angle and sent to the XY drive control unit 50. By this position change, the drive direction of the XY drive device 13 is indirectly corrected, and the corresponding shift between the operation direction of the joystick 8 and the drive direction of the XY drive device 13 is eliminated. In other words, if the operator tilts the joystick 8 to the front side of himself, the mirror body 14 will surely move to the front side of the operator.

Therefore, the operator can surely and easily move the mirror body 14 to a desired position while continuing observation without checking the movement of the mirror body 14 one by one and without changing the position of the foot switch 15. You can As a result, the physical fatigue of the operator as well as the patient is reduced, and the mental fatigue of the operator is significantly reduced.

In addition, since the control unit 40 has a simple structure in which the signal conversion unit 43 is provided, the foot switch 15
The cost can be kept low compared to the one with a motor. A third embodiment will be described.

Here, as shown in FIG. 6, a microphone 60 is attached to the mirror body 14, and a microphone cord 61 derived from the microphone 60 is connected to a voice controller 62. This voice controller 6
A foot switch 5 is connected to 2. The voice controller 27 is connected to the XY drive control unit 50, the focus control unit 51, and the zoom control unit 52 in the gantry 1 via the interface cable 28.

The foot switch 5 is the same as that shown in FIG. 10, and the momentary switches 6a, 6 for changing the magnification are used.
b, a focus adjustment momentary switch 7a, 7b, and a joystick 8, and a signal for driving the XY drive device 13 back and forth and left and right, an up / down signal for a zoom mechanism (not shown) of the mirror body 14, Mirror body 14
It is possible to output a total of eight types of control signals of up / down signals of the focus mechanism (not shown). The focus control unit 51 adjusts the focus of the mirror body 14. The zoom controller 52 changes the magnification of the mirror body 14.

As shown in FIG. 7, the voice controller 62 includes an interface section 70 and a voice recognition device 7.
Have 4. The voice recognition device 74 includes the microphone 60.
It recognizes the input voice to and outputs the same eight types of control signals as the foot switch 5 according to the recognition content.

The interface section 70 includes a signal input / output section 71 connected to the voice recognition device 74, a signal input / output section 72 connected to the foot switch 5, and a signal input / output section 73 connected to each of the control sections 50, 51 and 52. Have. Furthermore, the interface unit 70, as shown in FIG.
2,83.

The signal input / output unit 71 selectively outputs various signals from the voice recognition device 74 from a plurality of output terminals in parallel. Of this selection output, the focus up signal is supplied to one input end of the OR circuit 81, and the focus down signal is supplied to one input end of the OR circuit 82. Although not shown, other selection outputs are similarly supplied to a plurality of OR circuits.

The signal input / output unit 72 selectively outputs various signals from the foot switch 5 from a plurality of output terminals in parallel. Of this selection output, the focusing up signal is supplied to the other input terminal of the OR circuit 81, and the focusing down signal is supplied to the other input terminal of the OR circuit 82. Although not shown, other selection outputs are similarly supplied to a plurality of OR circuits. The outputs of all the OR circuits including the OR circuits 81 and 82 are supplied to the signal input / output unit 73. Foot switch 5 input to the signal input / output unit 72
Are supplied to the OR circuit 83.

The signal input / output unit 73 includes an XY drive control unit 5
0, the focus control unit 51, and the zoom control unit 52 input limit signals indicating that the respective drive units have reached the drive limit. These limit signals are supplied from the signal input / output unit 73 to the OR circuit 83. The output of the OR circuit 83 is a CPU (not shown) for controlling the voice recognition device 74 via the signal input / output unit 71.
Sent to the interrupt input terminal of.

In this way, the control signals of the two systems from the voice recognition device 74 and the foot switch 5 are OR-operated for each control function in the interface unit 70 and integrated into the control signal of one system, and the XY drive control unit 50, focus It is configured to be sent to the control unit 51 and the zoom control unit 52. The operation will be described.

When the operator utters "focus up" which is a command voice for raising the focus mechanism to the microphone 60 attached to the mirror body 14, the voice waveform is converted into an electric signal by the microphone 60. , Is input to the voice recognition device 74 of the voice controller 62 via the microphone code 61.

In the voice confirmation device 74, the inputted electric signal is frequency-analyzed to form pattern data, and the similarity between it and each standard pattern data of a plurality of command voices registered in advance is calculated by the simple similarity method. Calculate Of the similarities calculated in this way, a control signal corresponding to the command voice of the standard pattern data having the highest similarity, in this example, a focus-up signal is sent to the interface unit 71.

In the interface section 70, the focus up signal from the voice recognition device 74 is sent to the signal input / output section 71.
And is sent to the focus control unit 51 via the OR circuit 81 and the signal input / output unit 73. At this time, the focus control unit 51 drives the focus control motor in the mirror body 14 to perform focus up.

When the operator performs a focus-up operation with the foot switch 5, a focus-up signal emitted from the foot switch 5 is taken in from the signal input / output unit 72, which causes the OR circuit 81 and the signal input / output unit 73 to operate. To the focus control section 51. As a result, focus is increased in the same manner as above.

At this time, the focus-up signal input from the signal input / output unit 72 is also input to the OR circuit 83,
From there, it is also sent to the CPU for controlling the voice confirmation device 74 via the signal input / output unit 71. CPU
Switches the voice confirmation device 74 to interrupt processing in response to the input. The interrupt processing program stops the output of the control signal due to the voice input at that time.

Therefore, the XY drive control unit 50, the focus control unit 51, and the zoom control unit 52 can be controlled by both the voice confirmation device 74 and the foot switch 5, but when both are operated simultaneously. The operation input by the foot switch 5 is prioritized, and the operation input by the voice confirmation device 74 is canceled.

Further, for example, when the focus mechanism reaches the drive limit, the limit signal indicates the limit signal.
1 to the CPU via the signal input / output unit 73, the OR circuit 83, and the signal input / output unit 71. As a result, the voice confirmation device 74 switches to interrupt processing, and the control signal output by voice confirmation is stopped. This is the same for any of the focus down signal, zoom up signal, zoom down signal, and XY drive control signal.

As described above, since the XY drive device 13, the focus mechanism, and the zoom mechanism can be controlled by two systems of voice input and foot switch operation, for example, the main operator is in charge of voice input and the sub-operator is the foot switch. If operated, both the main operator and the sub-operator can control the surgical microscope. That is, it is not necessary to change the position of the foot switch 5 each time even when the main surgeon and the sub surgeon are exchanged.

Even if the voice confirmation device 74 erroneously recognizes the voice command uttered by the main surgeon, since the foot switch operation has a higher priority than the voice input, the assistant surgeon using the foot switch 5 immediately It is possible to stop malfunctions and perform correct operation input. It is also conceivable to provide a function of stopping driving based on a voice input when at least one of the operation switches of the foot switch 5 is operated.

When there is only one operator who operates the surgical microscope, a device such as a shaver or a bipolar device that generates a large amount of noise is used, and even if voice recognition is impossible due to the influence of the noise, the foot is immediately detected. It is safe because it can be changed to control by the switch 5.

In providing an operating mechanism for releasing the camera, turning on and off the light, etc., considering that the operation does not necessarily have to be performed by the operator, the operating mechanism is used as an assistant foot. Since it can be provided in the switch 5, a measure for increasing the number of registered words of the voice recognition device 74 becomes unnecessary, and the voice recognition rate can be improved.

In the case of selecting the function of each operation switch of the foot switch by key input or voice input as in Japanese Patent Laid-Open No. 57-88627, display means for displaying the switching state of the function is provided. As the height increases, the surgeon operates the foot switch while checking the display one by one, which results in poor operability.
