A surgical microscope apparatus incorporating a frame portion placed on a floor, a microscope body for stereoscopically observing a portion to be operated, an arm portion supported by the frame portion and arranged to suspend the microscope body, and an endoscope for observing a blind spot for a stereoscopic observation field of view. The frame portion has a light source unit for generating light for illuminating a portion observed with the endoscope and a camera control unit for processing an observed image of an observed portion obtained by the endoscope. A light guide fiber extending from the light source unit to the microscope body and capable of supplying light to the endoscope, and a camera cable for transmitting the image observed with the endoscope to the camera control unit extend in the arm portion. The microscope body is provided with an end of the light guide fiber for connecting the endoscope and a camera head connected to the camera cable.

Surgical microscope apparatus

An apparatus for holding a medical instrument, such as an endoscope, in place without exerting an undue force on an insertion hole in an abdominal cavity of a subject even when the arm of a scope-holding section is unlocked, includes a four-link parallelogram mechanism. The four-link parallelogram mechanism includes a support arm for supporting a treating tool, an arm section parallel to the support arm and upper and lower arm sections connected to the upper and lower end sides of the support arm and arm section in a parallel relation. A support mechanism supports the arm sections of the four-link parallelogram mechanism to allow the arm sections to be moved in left/right and up/down directions, while being rotated, so that a straight line connecting an intersecting point P of a center line of the treating instrument inserted into an insertion hole in an abdominal wall of a subject and the center of the insertion hole to spherical bearings of the arm is set parallel to the upper and lower arm sections.
