Abstract[English]
An ophthalmic surgical instrument includes a handpiece configured to be held by a user, and a working tip coupled to a distal end of the handpiece that includes a proximal opening configured to be disposed outside an eye, a distal opening configured to be disposed inside the eye and expose a tool to the inside of the eye, and a channel between the openings. When the distal opening is disposed inside the eye and the proximal opening is uncovered the proximal opening permits the channel to be in fluid communication with ambient atmosphere, the channel is configured to enable passive aspiration of fluid from inside the eye, such that the fluid flows from the distal to the proximal opening and into the ambient atmosphere. The tool comprises forceps, scissors, a delamination spatula, a pick, an illumination fiber, or a laser fiber.[French]
Un instrument chirurgical ophtalmique comprend une pièce à main conçue pour être tenue par un utilisateur, et une pointe de travail couplée à une extrémité distale de la pièce à main qui comprend une ouverture proximale conçue pour être disposée à l'extérieur d'un œil, une ouverture distale conçue pour être disposée à l'intérieur de l'œil et exposer un outil à l'intérieur de l'œil, et un canal entre les ouvertures. Lorsque l'ouverture distale est située à l'intérieur de l'œil et que l'ouverture proximale est découverte, l'ouverture proximale permet au canal d'être en communication fluidique avec l'atmosphère ambiante, le canal est conçu pour permettre une aspiration passive de fluide depuis l'intérieur de l'œil, de telle sorte que le fluide s'écoule de l'ouverture distale à l'ouverture proximale et dans l'atmosphère ambiante. L'outil comprend des pinces, des ciseaux, une spatule de délamination, un pic, une fibre d'éclairage ou une fibre laser.
