Abstract
Abstract A fiber optic probe is disclosed for delivering laser radiation from a medical laser system to a treatment site. The probe includes a handpiece having an axial channel. The axial channel includes an intermediate mating region of reduced diameter. A tip piece having a fiber located therein is mounted on the front end of the handpiece. The input end of the fiber is mounted in a ferrule which is received in the reduced diameter mating region of the handpiece. A tail piece which includes an optical fiber is mounted at the rear end of the handpiece. The delivery end of the fiber in the tail piece is mounted in a ferrule and is also received in the mating region of the handpiece. The two ferrules are spring biased together to maximize coupling efficiency. The mating region is spaced from the front end of the handpiece so that the force on the mating region, caused by the torque imparted to the tip piece during use, is less than it would be if the mating region were located at the front end whereby the coupling efficiency is maintained. The handpiece is designed to be reused after sterilization in an autoclave.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
212 words
A fiber optic probe comprising: an elongated handpiece having front and rear ends and an axial channel formed therein and extending between said ends, said channel including a mating region spaced from said front end; a tip piece including a first elongated optical fiber, with one end of the first fiber being mounted in a first ferrule; and a tail piece including a second elongated optical fiber, with one end of the second fiber being mounted in a second ferrule, and with a portion of said tip piece being mounted within said channel from the front end of the handpiece and the tail piece being mounted into said channel from the rear end of the handpiece in a manner such that the first and second ferrules are positioned within said mating region of the channel and in abutting relationship and with the portion of the tip piece extending between said one end of the fiber and the front end of the handpiece being at least twenty five percent of the length of the remaining portion of the tip piece that extends beyond the front end of the handpiece whereby efficient optical coupling between the ends of the optical fibers can be maintained as force is exerted on the tip piece during use.
