In the present embodiment having such a configuration,
A chair 4 on which the surgeon 5 sits is prepared so that the surgeon 5 can perform a long-time operation using the endoscope 7 in a comfortable posture, and an operator's front view device for stereoscopic observation is also provided. The operator monitor 6 is integrally provided on the chair 4 so that when the operator 5 changes the height or moves to the left or right for an operation, he or she can easily operate the chair by operating the foot switch 27. 4 and in that case the operator's monitor 6 is integrally provided on the chair 4, so that the operator 5 can observe in the same observation state without changing the position of the operator's monitor 6. In this way, the surgeon 5 is characterized by being able to perform surgery in a convenient state.

It should be noted that, in order to integrally hold the operator's monitor 6 on the chair 4 by means of the columns 31 etc.
Is held by the chair drive device 28 so as to be movable (drivable), a movable holding means for movably holding the operator monitor 6 is formed in association with the movement of the chair 4.

Next, the operation of this embodiment will be described. When the surgeon 5 performs an operation using the endoscope 7, sitting on the chair 4
By stepping on the foot switch 27, the height and the direction of the chair 4 can be easily set to the position and the direction where the surgery can be easily performed.

A monitor 6 for an operator is integrally held on the chair 4 by a support column 31 or the like.
The distal end side of the flexible shaft 38 is formed by a flexible shaft 38 having flexibility, and is bent in a substantially right angle in advance as shown in FIG. 3, for example, when the operator 5 sits on the chair 4, the distal end of the flexible shaft 38 is operated. The operator monitor 6 held via the operator holding section 39 is arranged in front of the operator's eye.

In this case, the operator's monitor 6 is placed in front of the operator's eye 5, but if the operator 5 is not in an appropriate state when performing an operation, the operator 5 uses the foot switch 27.
It is possible to set to an appropriate state by operating.

For example, when the position of the operator's monitor 6 is too high or too low, stepping on the pedal 33c or 33d of the foot switch 27 moves the column 31 up or down to move it to an appropriate height. Can be set (adjusted) to.

After the operator's monitor 6 is set at a proper height position in front of the eyes in this manner, the positions of the liquid crystal monitors 23L and 23R on the left and right of the operator's monitor 6 are set on the left and right of the operator 5 next. The eyes 24L and 24R are adjusted to an appropriate observation distance state.
For example, by operating the pedal 33g / 33h of the foot switch 27, the operator's monitor 6 (opposite the operator 5)
The angle is adjusted so that the display surface is parallel to the operator's 5 face.

Thereafter, the pedals 33e and 33f are operated to adjust the height of the nose pad 41 and the position thereof in the front-rear direction, and the end of the nose pad 41 protruding from the nose is easily observed by the operator 5. Make sure the department side hits.

By performing these operations, the left and right liquid crystal monitors 23L are positioned at positions of an appropriate observation distance immediately before the right and left eyes 24L and 24R of the operator 5, with the observation distance being restricted by the nose pad 41. , 23R (the display surface thereof) can be set.

Images are formed on the left and right liquid crystal monitors 23L and 23R by the left and right objective optical systems 16L and 16R of the endoscope 7, transmitted by the relay lens systems 17L and 17R, and transmitted to the CCD 1.
The left and right optical images that have been image-formed on the 8L and 18R and have been photoelectrically converted are displayed as left and right endoscopic images.

The operator 5 can stereoscopically recognize the left and right endoscopic images by observing them. That is,
The operator 5 can stereoscopically observe the site to be operated on in the abdomen of the patient 2, and can stereoscopically recognize the tip side even when using a surgical treatment tool (not shown). Therefore, surgery is easy. Further, since the operator 5 can perform an operation while sitting on the chair 4 in a comfortable posture, the burden can be reduced even in the case of a long-time operation.

Further, even if an operation such as rotating the chair 4 to move the chair 4 in a substantially horizontal direction is performed by operating the switch 27 for a procedure during an operation, the operator's monitor 6 is not supported. Since it is held integrally with the chair 4 by 31 or the like, the operator 5 can observe the endoscopic image without changing the holding state of the operator monitor 6. Therefore,
It is possible to eliminate the drawback that a nurse or the like has to move and adjust the monitor observed by the operator 5 in accordance with the movement of the operator 5 when the operator is not integrally attached to the chair 4.

Further, in the present embodiment, the nose pad 4
Although the observation distance of the operator's monitor 6 by the operator 5 is regulated by 1, the operator 5 can set the detached state apart from the operator's monitor 6 by moving the head backward. Even during the operation, the operator 5 can be set to the disengaged state by simply moving the head to the rear side, and can be set to the observation state by moving to the front where the nose pad 41 is located.

Therefore, even when the operator performs an operation for a long time as compared with the case where the operator observes in a surely worn state such as HMD or FMD, the operator feels a burden such as a feeling of oppression. Easy and smooth endoscope 7
It is possible to carry out therapeutic treatments such as surgery (which takes longer time than diagnosis as well as).

Therefore, according to the present embodiment, even when the operator 5 uses the endoscope 7 to perform a long-term operation, etc., the operator 5 has a comfortable posture and reduces the burden. Thus, there is an effect that an image display device for an endoscope capable of displaying an endoscopic image can be realized.

As a modified example of the first embodiment,
For example, while holding the lower end of the column 31 so that it can move up and down,
Further, it may be configured to be rotatably held. And
After the operator sits on the chair 4, for example, by operating the rotation setting pedal provided on the foot switch 27, the pillar 3
The lower end of 1 may be rotated in the clockwise direction in FIG. 3 to be set to the state as shown in FIG. 3, that is, the state in which the operator's monitor 6 is placed in front of the operator 5 sitting.

Further, after the pivotal position of the support column 3 is set and the nose pad 41 etc. is set in an appropriate state, a means for storing information on the set rotational position of the support column 3 is provided, for example, during surgery. When a release pedal provided on the foot switch 27 is operated, for example, even if it is allowed to stop for a while, the column 31 is rotated counterclockwise to move the support 5 from the front of the operator 5 to the operator. The monitor 6 may be detached (retracted), and may be reset to the stored rotation position by operating the rotation setting pedal or the like again.

In this case, even if the operator 5 does not move his or her head, the operator's monitor 6 is set to a detached state by a switch operation, or set again to a proper observation position. You can also do it.

Further, in the above-described embodiment, by forming the upper side of the support column 31 with the flexible shaft 38, the operator's monitor 6 is provided before the operation or in the vicinity of the operator 5 in front of the operator 5 manually. Is set to hold
It may be formed by an L-shaped link mechanism or the like.
In this case, the connecting portion of the link mechanism may be structured to be rotatable manually or by an electric drive means.

Further, a memory or a storage device as information storage means is provided in the operator monitor control device 26, etc.
The setting information of the nose pad 41 and the like are stored together with the ID of the operator, and the corresponding setting information is read by inputting the ID of the operator 5 when using the next time, and the same setting state is again read with the setting information. It may be possible to easily set to. Therefore, the motors 34, 43 to 45, etc. may be provided with position detecting means.

As shown in FIG. 3, the chair 5 can be moved up and down and turned. However, the chair 5 can be further moved in the left and right directions, and can be moved in the front and back directions. For example, an operation pedal formed on the foot switch 27 may be provided.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 shows the configuration of an endoscopic surgery apparatus 51 including the second embodiment. In the present embodiment, instead of the foot switch 27 of the endoscopic surgery device 1 according to the first embodiment, a microphone 52 for inputting voice and a surgeon 5 or the like convert the microphone 52 into an electric signal. Based on the operation instruction recognized by the voice recognition device 53 which recognizes the information of the operation instruction by the voice (signal) by the input of the voice signal, the operator gives a corresponding instruction control signal. The monitor monitor control device 26 and the CPU 54 for outputting to the chair drive device 28 are provided.

The microphone 53 is attached to, for example, the lower end of the operator's monitor 6, and the output signal of the microphone 53 is input to the voice recognition device 53. The other configurations are the same as those in the first embodiment. The microphone 53 may be of a type that is worn on the head of the operator 5.

In the case of the endoscopic operation device 51, when the operator 5 inputs a voice operation instruction, the voice recognition device 53 recognizes the operation instruction content, and a signal corresponding to the operation instruction content is transmitted. It is given from the CPU 54 to the operator monitor control device 26 and the chair drive device 28.

Then, similarly to the case described in the first embodiment, the position adjusting mechanism of the nose pad 41 and the like can be controlled via the operator monitor control device 26. The present embodiment has substantially the same effect as that of the first embodiment.

As a modified example of the second embodiment,
For example, the chair drive device 28 may be controlled by the foot switch 27 as in the first embodiment, and the operator monitor control device 26 may be controlled by voice. Alternatively, the operator 5 may perform the control by selecting from the foot switch 27 and the voice.

In the first or second embodiment, a mechanism for adjusting the distance between the liquid crystal monitors 23L and 23R is further provided so that both eyes 24L and 2L of the operator 5 can be adjusted.
It may be possible to deal with the case where the distances of 4R are different.

In the above description, the stereoscopic endoscope 7 is adopted and the operator's monitor 6 displays left and right endoscopic images with parallax. System, a relay lens system, and an observation optical system with an eyepiece optical system use a single (monocular) endoscope, and the operator's monitor 6 displays the same endoscopic image left and right in a pseudo three-dimensional manner. It can also be applied to the case of an endoscopic surgery device that displays. In this case, the imaging device, CCU, brightness control circuit, etc.
