Abstract: With respect to a forceps type treatment instrument including an ultrasound probe that protrudes from a treatment instrument main body at a position separated to a distal end side from a shaft portion, and a jaw that is displaceable between a closed state and an opened state by being linked with swing action of an clamp arm in a position separated to a distal end side from the shaft portion, stoppers are extendedly provided toward a clamp arm side from a treatment instrument main body side in a state in which edge portions at a distal end side are set to located at a distal end side from a locus of a proximal end of the jaw, and entry of a living body into a gap of the treatment instrument main body and the clamp arm is restricted.

Abstract: A surgical instrument includes: a handpiece; a movable member configured to transmit a driving force to a treating member to treat a subject by moving relatively to the handpiece; and a connector arranged inside the handpiece, and including a strip to apply a pressing force to the movable member. The movable member includes a first conductive portion formed therein. The connector includes a second conductive portion formed on the strip. The second conductive portion abutting against the first conductive portion to connect the movable member and the handpiece electrically. The second conductive portion of the connector is a molded interconnect device constituting a three-dimensional circuit.
