Abstract: The suture thread shifting device is characterized in that even when the incision portion of surface layer of the body is small, front edge (11) of the device has a sectional configuration (for example, circular section of relatively small diameter) suitable for allowing the front edge to reach a region in arthroscopic or endoscopic viewing field and that the device with the suture thread engaging in the front edge (11) can shift the suture thread from a position on the operating surgeon's side (near side position)to a position remote from the operating surgeon (far side position).
