REUSABLE ENDOSCOPIC SURGICAL INSTRUMENT

摘要

A reusable endoscopic surgical instrument includes a tool assembly retained within a detachable handle assembly. The tool assembly consists of an outer sleeve, an inner extension within the outer sleeve, and surgical jaws such as scissors or graspers. The inner extension and outer sleeve are longitudinally translatable with respect to each other to pivot the jaws. In one embodiment, the extension can be translated out of engagement with the jaws to permit disassembly of the instrument for cleaning and changing jaw assemblies. Relative rotation between a thumb loop and a finger loop on the handle assembly longitudinally translates the extension relative to the sleeve, and thus opens and closes the jaws. The handle assembly can have a pair of ports or a single rotatable port which allows the user to select between instrument orientations configurations.
