Title
(EN) CORNEAL LENTICULE EXTRACTION TOOL
(FR) OUTIL D’EXTRACTION DE LENTICULE CORNÉENNE
Abstract
(EN)
Improved corneal lenticule extraction tools which integrate defined angles, tip features, and the use of vacuum into the tool to aid in the removal of the lenticule. The tool has a body and a tip each with an internal air channel. The tip has a straight portion and a curved portion at a distal end, with one or more orifices disposed on the curved portion. The body either has a mechanism for generating a vacuum in the internal air channel, such as a resilient diaphragm, or is connected to an external vacuum source. Use of tip features and angles helps the surgeon find tissue edges during tissue removal. The use of vacuum aids to draw the tissue to the tool and to hold the tissue by the tool. The improved tools improve speed of extraction as well as completeness of extraction so that no tissue is left behind.

La présente invention concerne des outils améliorés d’extraction de lenticule cornéenne qui intègrent des angles définis, des caractéristiques de pointe, ainsi que l’utilisation du vide dans l’outil pour faciliter l’élimination de la lenticule. L’outil présente un corps et une pointe ayant chacun un canal d’air interne. La pointe présente une partie droite et une partie incurvée au niveau d’une extrémité distale, un ou plusieurs orifices étant disposés sur la partie incurvée. Le corps présente soit un mécanisme de génération d’un vide dans le canal d’air interne, tel qu’un diaphragme élastique, soit est connecté à une source de vide externe. L’utilisation des caractéristiques de pointe et des angles aide le chirurgien à trouver les bords du tissu pendant l’élimination du tissu. L’utilisation du vide aide à tirer le tissu vers l’outil et à maintenir le tissu par l’outil. Les outils améliorés améliorent la vitesse d’extraction et assurent que l'extraction est complète de sorte qu’aucun tissu n’est laissé derrière.
