Abstract
A hand piece for delivering energy from a laser to a target through a fiber tip includes an elongated handle having a proximal end and a distal end. An axial bore traverses the handle along a longitudinal axis thereof. A fiber tip holding mechanism is fixed within the axial bore of the handle and includes a forward section fixed with the handle, a spring, and a rear section that includes a hollow collet projecting forward therefrom that traverses the spring and the forward section. The forward section is slidable rearward towards the rear section to compress the spring in a rear position. The spring urges the forward section forward into a forward position. A chuck is fixed with the forward end of the fiber tip holding mechanism and includes a tapered sleeve and two or more oppositely tapered jaws.
