Title (EN) NON-REUSABLE LENS CELL FOR A SURGICAL LASER HANDPIECE
(FR) OBJECTIF NON REUTILISABLE POUR PIECE A MAIN DE CHIRURGIE LASER
Abstract:
(EN) A non-reusable lens cell (20) for a surgical laser handpiece (22) having a contact surface with an aperture (28) for exciting a laser beam (24) includes a housing having a first connector at a first end for engaging a laser source and a second connector at a second end for engaging a handpiece; and a hydroscopic lens (20) device for focusing the laser beam through the handpiece proximate the aperture (28) and being degradable in the presence of moisture during attempts at sterilization to deteriorate the lens device, disrupt the focus and thwart reuse of the lens cell.
(FR) L'invention porte sur un objectif non réutilisable (20) pour pièce à main (22) de chirurgie laser présentant une surface de contact avec une ouverture (28) d'excitation d'un faisceau laser (24) et comprenant: un logement muni d'un premier raccord placé à une première extrémité et destiné à entrer en contact avec une source laser, et d'un deuxième raccord placé à sa deuxième extrémité et destiné à entrer en contact avec la pièce à main; ainsi qu'un objectif hygroscopique (20) servant à focaliser le rayon laser traversant la pièce à main à proximité de l'ouverture (28). Ledit objectif se dégrade en présence d'humidité lorsqu'on tente de le stériliser, ce qui dérègle le foyer et empêche sa réutilisation.
