Abstract

A medical instrument holding device is provided with a holding unit which holds a flexible scope so that the flexible scope can be moved and tilted and which has a balance mechanism for causing the weight of the flexible scope and a link mechanism unit to balance each other. In the medical instrument holding device, the holding unit of the flexible scope is provided with a transmissive photointerrupter for detecting the attachment and removal of the flexible scope. The medical instrument holding device is provided with a control unit which, when the state that the flexible scope is removed from the holding unit is detected by the photointerrupter, outputs a control signal on the basis of the detection signal from the photointerrupter, the control signal switching a lock unit to an affixed state and causes the lock unit to affix a first joint.

Description

technical field [0001] The present invention relates to a medical device holding device for holding an endoscope for observing the inside of a body cavity of a subject, a surgical microscope for observing the inside of a craniotomy, a treatment tool for treating an affected part, and the like. Background technique [0002] In surgical operations such as neurosurgery, a method of magnifying and observing minute surgical sites with a surgical microscope is used. As such microscope holding devices, a medical device holding device equipped with a balance mechanism that maintains three-dimensional balance using the principle of a balance, and a medical device holding device equipped with a balance mechanism that maintains vertical balance using the reaction force of a spring have been mainly developed. [0003] In surgical operations such as gastrointestinal surgery, a method of observing the inside of a body cavity through a rigid scope is used. The rigid scope is usually held ...
