SURGICAL TOOL CONTAINMENT DESIGN FOR SURGICAL INSTRUMENTS

摘要

A surgical instrument (10) includes an outer tube (12) having an open distal end (20) and a first radially extending surface (101); and an inner member (14) positioned to move within the outer tube (12) and having a surgical tool (16) and a second radially extending surface (80). The first radially extending surface (101) and the second radially extending surface (80) are positioned to contact each other to maintain the surgical tool (16) within the central bore if the surgical tool (16) separates from the inner member (14).
