ABSTRACT:
A laser surgical instrument is embodied as a handpiece supportable on the wrist and forearm of a surgeon. The handpiece is connected by an umbilical cord to a remote console. An internal shutter mechanism is actuated by steady finger pressure applied by the surgeon at a fixture grasped by the hand during use. An annular aiming beam is projected through an aperture in a physical distance gauge to focus concentric with the surgical laser beam.
