A surgical instrument of the present disclosure includes: a conductive cable member formed into a cable-like shape; a conductive outer shell covering a circumference of the cable member; first and second insulating portions made of materials having higher insulation properties than the cable member and the outer shell; a projecting portion projecting from a projecting insulating portion, which is one of the first and second insulating portions, toward a recessed insulating portion, which is the other, the cable member being inserted into the projecting portion; a conductive leading end portion separated from the recessed insulating portion and the outer shell, the leading end portion being bendable using tension of the cable member with an end portion connected thereto; and a power supply cable in a cable-like shape arranged inside the first and second insulating portions for supplying an electric power from outside to the leading end portion.

Surgical instrument for surgical assist robot

High-frequency forceps for medical use that include a manipulation part including a grasping portion that is conductive; a cylindrical part that is inflexible, through which a wire for manipulation of the grasping portion and a cable for supplying current to the grasping portion are guided; and an insulating part that electrically insulates the manipulation part from the cylindrical part. The cylindrical part includes: an outer layer made of an insulating material; an inner layer made of an insulating material; and an intermediate layer located between the outer layer and the inner layer, and having a lower insulation resistance and a higher stiffness than the outer layer and the inner layer.
