An aspirating handpiece for laser surgical applications, includes an elongated hollow cylindrical probe member (22). A proximal end (24) of the probe member is arranged such that aspiration means can be connected therewith, and a distal end (26) of the probe member has an aperture therein for receiving matter to be aspirated. An elongated optical fiber (50) extends along the probe member with the distal end (59) of the fiber proximate the aperture therein. The proximal end (52) of the fiber is arranged to receive laser radiation. The probe member has an inside diameter progressively increasing from the distal end thereof to the proximal end thereof.

[ What is claimed is:] [1.] A handpiece for laser surgical applications, the handpiece for delivering laser radiation from a laser to a site for treating biological material at the sites, and connectable with a vacuum pump for aspirating treated material from the site, comprising:an elongated hollow cylindrical probe member having proximal and distal ends, having an inside diameter progressively increasing from the distal end thereof to the proximal end thereof, and having a groove in an inner wall thereof at the distal end thereof; the proximal end of said probe member arranged such that the vacuum pump can be connected therewith for providing an aspiration force within said probe member and the distal end of said probe member having an aspiration aperture axially located therein at the distal end thereof for receiving treated material to be aspirated; andan elongated optical fiber having a proximal and a distal end, the proximal end of said fiber arranged to receive laser radiation from the laser for delivery to the material to be treated, said elongated fiber extending along said probe member on the inside thereof, with the longitudinal axis of said optical fiber laterally displaced from the cylindrical axis of said probe member and with the optical fiber located in said groove at the distal end of said probe member with the distal end of said fiber proximate said aspiration aperture therein.
