STERILE ADAPTER, FASTENING STRUCTURE OF WHEELS, AND FASTENING STRUCTURE OF SURGICAL INSTRUMENT

摘要

Disclosed is a sterile adapter. The sterile adapter is interposed between an instrument holder formed at a surgical robot arm and a surgical instrument mounted on the instrument holder, wherein the sterile adapter comprises: a body portion comprising a first surface facing the instrument holder, and a second surface facing the surgical instrument; a first wheel which is elastically supported in the body portion, is exposed to the first surface, and is fitted to a first drive wheel formed at the instrument holder; and a second wheel which is elastically supported in the body portion, is exposed to the second surface, and is fitted to a second drive wheel formed at the instrument. An elastic structure is applied to the sterile adapter to allow the wheels formed in the sterile adapter to be pushed in both directions, thereby enabling the easy and convenient mounting of a surgical instrument on a robot arm without applying a separate elastic structure to the instrument holder or the instrument.
