SURGICAL INSTRUMENT AND ADAPTER FOR SINGLE PORT SURGERY

摘要

Disclosed is a surgical instrument. The surgical instrument comprises: a tube-shaped shaft extended in the longitudinal direction; a guide tube coupled so as to be inserted into the shaft, of which the end is bent by a certain angle; and an effector for carrying out operation necessary for surgery, coupled to the end of the guide tube. The surgical instrument can implement wrist motion and gripping motion of the effector by inserting and drawing the guide tube and a torque cable into and from the shaft instead of using a known pulley wire method, and thus the shaft of the surgical instrument can be made slimmer and the instrument structure can be applied in case a wire cannot be used.
