STEREO LAPAROSCOPE WITH SYNCHRONIZED OPTICS

摘要

This invention is a stereo laparoscope (100) for producing a stereoscopic optical image of an intra-corporeal region to be viewed through a small incision. The stereo laparoscope includes a conventional elongated tubular casing (140) having an illuminating window, and a left (124), a right (126) observation windows disposed in a distal extremity thereof, said distal extremity for insertion within the human body. At least two separate optical imaging assemblies (128, 130) are disposed within the casing to produce a stereoscopic optical image. At least one of the optical imaging assemblies (130) is moveable relative to the other. Focusing devices (108, 116) are synchronized with variation in depth perception to permit variation in image distance responsive to variation in depth perception.
