Apparatus for directing 10.6 micron laser radiation to a tissue site

摘要

A CO₂ (10.6 micron) medical delivery end probe (21) is described which enables line-of-sight viewing of a surgical site internally within a body within the very same endoscope (12) used to house the probe (21). The end probe (21) includes two different sections of n1 air core hollow waveguides (23 and 28), obliquely related to one another. A mirror (27) is positioned to reflect radiation from the exit end of the initial guide (23) to the entry end of the main section (28). A bridge (35) which is especially adapted for use in an endoscope with both such a probe (21) and a telescope (14) is also described. Moreover, an adaptor having the initial optical guide section (23) discussed above enabling straight end probes to be used is also described.
