ABSTRACT:
A coupler 30 for use with medical laser delivery systems is disclosed. The delivery system includes an articulated arm and an endoscope 42. The coupler 30 connects the arm to the endoscope. The coupler includes an axially extending tube 46 receivable in the bore 48 of the endoscope. The tube facilitates alignment of the coupler with the endoscope. The coupler is also provided with a telescope optical system (50, 52) for adjusting the diameter of the beam at the entrance to the endoscope to reduce clipping of the beam thereby enhancing transmission.
