ENDOSCOPIC SURGICAL LASER SYSTEM

摘要

A surgical laser system for performing surgical operations upon a patient. The system includes a laser which could be a continuous wave laser which can be continuously energized if desired, and means for continuously illuminating the work site (patient tissue). There is further provided means for concurrent observation of the site and exposure of the site to the laser beam. Additionally, novel use of a light-trans-missive pellicle provides a protective physical barrier between the inclement atmosphere associated with the surgical work site(moisture, mucus) and expensive optics including a beam splitter employed in the endoscope.
