SURGICAL INSTRUMENT, COUPLING STRUCTURE OF THE SURGICAL INSTRUMENT, AND METHOD FOR ADJUSTING ORIGIN POINT

摘要

Disclosed are a surgical instrument, a coupling structure of the surgical instrument, and a method for adjusting the origin point. The surgical instrument comprises: a handle; a shaft detachably coupled to the handle and extended in one direction; a bending portion formed at a part of the shaft; a drive portion for producing a predetermined driving force, mounted on the handle; a location change portion for being transmitted with a driving force to change the location of one end of the shaft, thereby bending the shaft in the direction different from the extension direction, mounted on the handle; and a power transmission means for bending the bending portion by corresponding to the bent shaft. It is possible to conveniently and freely bend the shaft, to attach or detach the shaft to or from the handle, and to allow for a user to conveniently couple the shaft to the handle in case of attaching or detaching.
