Surgical microscope apparatus

A surgical microscope apparatus including a frame portion, an arm portion supported by said frame portion and having an end capable of moving three-dimensionally, and a microscope body having first observation means for stereoscopically observing a portion to be operated on, said surgical microscope apparatus comprising:

• a light-source for emitting light for illuminating a portion to be operated on;
• first light guiding means for guiding the light from the light-source to the portion to be operated on;
• second observation means for observing the portion to be operated on;
• and
• second light guiding means for supplying the light to the second observation means,
• wherein the second light guiding means is optically diverged from the first light guiding means.

A surgical microscope apparatus comprising:

• a frame portion placed on a floor;
• a microscope body having a stereomicroscope optical system for stereoscopically observing a portion to be operated on, and an outer surface;
• an arm portion supported by the frame portion and arranged to suspend the microscope body at a position away from the frame portion;
• an endoscope for observing a blind spot of an observation field of view of the stereomicroscope optical system;
• a light source unit arranged to emit light to illuminate a portion to be observed with the endoscope;
• light supply means having an end which is optically connectable to the endoscope and which is capable of supplying light from the light source unit to the endoscope;
• a control unit provided in the frame portion and arranged to process an observed image of an observed portion obtained by the endoscope;
• transmitting means having an end for interfacing the endoscope with the control unit and which transmits an observed image obtained by the endoscope to the control unit;
• and
• a connecting portion of the endoscope provided at the outer surface of the microscope body and structured to have end to the light supply means and the transmitting means;
• wherein the endoscope includes an elongated and hard insertion portion having an axial line and a distal end arranged to be inserted into the microscope body along the axial tine, an objective optical system disposed at the distal end of the insertion portion, the objective optical system having an optical axis extending to make a predetermined angle from the axial line, and identifying means for indicating a direction in which the optical axis of the objective optical system extends, wherein the identifying means is stereoscopically observable through the stereomicroscope optical system.
