Disposable Stereoscopic Endoscope System
First Claim
1. A disposable simultaneous stereo endoscope system, comprising,an imaging sub-system having two sub-apertures for defining the two stereo imaging channels and a demultiplexing beam splitter for splitting the two light beams to two imaging devices,an illumination sub-system further comprising a solid light source, an optical fibers based ring illumination path, and a wedged multi-facet illumination window,an electrically conductive heat sink for dissipating the heat generated by the solid light source and also for shielding end side of the endoscope,a metallic tube for shielding the opto-electronic components inside the endoscope from electromagnetic interferences,

Abstract
A disposable simultaneous stereo endoscope system is disclosed. The disposable endoscope does not include image relay. Instead, two electronic imaging sensors and solid illumination lighting are arranged inside the endoscope. A demultiplexing beam splitter is used for splitting the two imaging light beams to the two imaging devices. A wedged multi-facet illumination window is used to create an illumination field that is larger than the field of view of the imaging optics. An electrically conductive heat sink is engaged for dissipating the heat generated by the solid light source and also for shielding end side of the endoscope. The disposable endoscope is shielded from electromagnetic interferences. A repeater unit is used to electrically connect the disposable endoscope with a remote receiver and to increase the data transfer rate. An electrical isolation means is provided between the endoscope and an image processing and power conditioning unit to protect the endoscope against electric shock.
