DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical microscope used for operating a small affected area in, for example, neurosurgery, otolaryngology, orthopedic plastic surgery, or ophthalmology.

[0002]

2. Description of the Related Art In the medical field for treating a small diseased part by surgery, for example, in neurosurgery or ophthalmology, a delicate operation is performed while magnifying and observing the diseased part using a surgical microscope. Some surgical microscopes used in the medical field include, for example, Japanese Patent No. 2815.
There is a surgical microscope having a stereoscopic device disclosed in Japanese Patent No. 484. According to the operating microscope having this stereoscopic device, the operator does not remove his / her eyes from the eyepiece of the operating microscope during the operation, and the image from the objective section of the stereo microscope differs from the stereo microscope. The image from the objective section of the stereoscopic fiberscope having the optical axis can be simultaneously observed.

In recent years, in addition to the above-mentioned method using an operating microscope having a stereoscopic device, an affected part which cannot be seen as a blind spot of the operating microscope is used together with an observation means such as an endoscope. The technique of performing more appropriate treatment while observing and observing is becoming widespread. In the case of such an operation, the endoscope is used under observation with a surgical microscope, and thus the endoscope in such a usage method is referred to as an assist scope.

[0004]

The assist scope is not always used during the operation, but is generally used by an operator when he or she needs to observe the blind spot of an operating microscope. It is a typical usage. Therefore, when it is not necessary to use the assist scope, the assist scope is placed near the operator within the reach of the operator. The assist scope has, for example, a bag for holding the assist scope attached to the bedside, and is stored in the bag, or directly mounted on a drape covering a patient.

However, in such an arrangement method, even when the assist scope slides down from the drape or when the assist scope is used, the assist scope is easily placed in the bag. And couldn't get out of it.

Further, since the holder for the assist scope, the television camera, the light source, and the like are provided separately from the operating microscope, the equipment occupies a part of the space in the operating room. Or the cables connecting the assist scope and each of the devices may hinder the operation.

[0007] In order to avoid these problems, there is a proposal that a holder for an assist scope is provided in a housing of an operating microscope and the scope is held by the holder. However,
When attaching / detaching the assist scope to / from the holder provided on the operating microscope, the impact is transmitted to the housing of the operating microscope, causing the operating microscope itself to vibrate, causing the field of view of the operating microscope to shift during surgery. And may hinder delicate surgery.

[0008] Accordingly, the problem to be solved by the present invention is that the observing means such as an endoscope can be easily attached to and detached from the surgical microscope, and the surgical microscope may be vibrated when it is attached and detached. An object of the present invention is to provide a surgical microscope which is hardly provided and which is excellent in storage, installation and operability.

[0009]

In order to solve the above-mentioned problems, a surgical microscope according to the present invention is provided with holding means for holding observation means such as an endoscope used under the surgical microscope. The means is fixed to the housing of the surgical microscope via a vibration damping means.

According to this surgical microscope, the observation means used together with the surgical microscope is held by the holding means attached to the housing of the surgical microscope, so that the operator can easily take the observation means. This makes it possible to improve the removability of the observation means from the surgical microscope, the storage property, the installation property, and the operability thereof.

In addition, by providing a vibration damping means between the holding means for holding the observation means and the housing of the surgical microscope, when the observation means is attached to and detached from the holding means, the vibration is generated by the operation microscope. The possibility of transmission to the housing can be almost eliminated.

[0012]

The vibration generated when the assist scope 2 is picked up from above or the assist scope 2 is placed on the scope receiver 10 can be attenuated by the dampers 9 and absorbed. As a result, the vibration of the scope receiver 10 is hardly transmitted to the pedestal 8 and eventually to the housing 6 of the surgical microscope 1, so that even if the operator repeatedly uses or does not use the assist scope 2 during the operation, the operator Has almost no blur. Therefore, the surgeon can use the assist scope 2 together while looking into the surgical microscope 1 to concentrate and easily perform a delicate operation. Next, the surgical microscope according to the second embodiment of the present invention. 21 will be described with reference to FIG.

The operating microscope 21 according to the second embodiment comprises:
The shape and configuration of the holding device 22 are different from the shape and configuration of the holding device 7 of the above-described first embodiment. Therefore, the different parts will be described, and the other description will be omitted. Also, regarding the drawings, in FIG.
The same parts as those in the first embodiment are denoted by the same reference numerals.

The holding device 22 of this embodiment is mounted on the housing 6 via a pedestal 8 projecting horizontally from the upper part of the outer surface of the housing 6. From the bottom of the pedestal 8,

Therefore, it is a matter of course that the problem of the present invention can be solved by using the surgical microscope 21 according to the second embodiment. However, the second embodiment including the holding device 22 having the above-described shape and configuration is excellent in the following points.

When the assist scope 2 is held by the holding device 22, the ring 24 may be hooked on the hook 23. When removing the assist scope 2 from the holding device 22, the ring 24 may be removed from the hook 23. Even with such a layout, the damper 9 provided between the hook 23 and the pedestal 8 can attenuate and absorb the vibration generated in the hook 23. At the same time, in the assist scope 2, the insertion portion 12 and the like can freely swing with the engagement portion between the hook 23 and the ring 24 as a fulcrum. As a result, even if the assist scope 2 is operated during the operation,
Vibration is hardly transmitted to the pedestal 8 and the housing 6. Therefore, there is almost no possibility that the field of view of the operator is blurred during the operation.

The assist scope 2 and the holding device 22
Are engaged with each other by the hook 23 and the ring 24. This allows the surgeon to gain some momentum
When the hook 23 is hooked, there is almost no risk that the assist scope 2 will fall off the holding device 22.
