Ophthalmic surgical instrument

Abstract

Provided is an ophthalmic surgical instrument which can prevent curving of a pipe during a surgical procedure and can pull out a reinforcement sleeve by a required length such that the reinforcement sleeve covers the pipe. An ophthalmic surgical instrument (10) working in an eyeball includes a body portion (15) having a through-hole, a reinforcement sleeve (13) contacting an inner surface of the through-hole of the body portion (15), a pipe (12) passing through the inside of the reinforcement sleeve (13) and having a working portion (11) protruding from a tip end, and a movement member (17) connected to the pipe (12) and sliding in an axial direction of the ophthalmic surgical instrument to slide the pipe (12). A first slide mechanism allowing the reinforcement sleeve (13) to slide in the axial direction of the ophthalmic surgical instrument and a second slide mechanism allowing the pipe (12) to slide in the axial direction of the vitreous forceps are provided. Any one of the first and second slide mechanisms is an independent slide mechanism not influenced by the other slide mechanism.

Dependencies are inferred from the claim text.
