Coupler for a laser delivery system

摘要

A coupler (30) for use with a medical laser delivery system having an articulated arm and an endoscope (42) connects the arm to the endoscope (42). The coupler (30) includes an axially extending tube (46) receivable in the bore (48) of the endoscope (42). The tube (46) facilitates alignment of the coupler (30) with the endoscope (42). The coupler (30) has a telescope optical system (50,52) for adjusting the diameter of the laser beam at the entrance to the endoscope (42) to reduce clipping of the beam, thereby enhancing transmission of power from the laser to the intended target.
