Optical fiber-handpiece combination for medical laser treatments
First Claim
1. A multi-component handpiece device for use with a laser assembly comprising:
- an optical fiber, a micro-walled protective tube, a handpiece, and a cannula;
wherein said handpiece device has means for removably locking said optical fiber to said handpiece;
wherein a distal end of said optical fiber is temporarily protected prior to and during insertion into said handpiece by said micro-walled protective tube; and
wherein said micro-walled protective tube is removed to expose said distal end of said optical fiber before said means for removably locking said optical fiber to said handpiece is engaged.

Abstract
The present invention describes a multi-component handpiece that is both economical and practical for surgical laser treatment. A disposable optical fiber is inserted into a reusable handpiece. The distal end of the optical fiber is protected by a micro-walled protective tube to prevent the disposable fiber from chipping before and during insertion into the handpiece. Once the optical fiber is protected, it is inserted into the handpiece by threading the optical fiber through the cap, body, and cannula of the handpiece until the fiber extends slightly beyond the distal end of the needle. The micro-walled protective tube is removed from the end of the optical fiber, the optical fiber is positioned, and the cap is tightened. The cap and body of the handpiece cooperate to produce a tight friction fit that prevents longitudinal movement of the optical fiber during laser therapy. The tight friction fit holds the optical fiber in place without the use of adhesives, which allows for facilitated removal of the disposable fiber after use. Furthermore, a disposable fiber allows for convenient resterilization of the handpiece to eliminate the transmission of disease from one patient to the next without having to dispose of the entire handpiece following every laser procedure.
