摘要:
A surgical treatment apparatus includes a receptacle which is configured to abut onto a treatment section so that a predetermined clearance is formed between an electrode section and the treatment section when a grip member is closed relative to the treatment section. The surgical treatment apparatus includes a regulating section which is provided in the grip member so that a closing-direction end located on a closing-direction side of the grip member does not protrude from the receptacle toward the closing direction, the regulating section being made of a material harder than the receptacle, and a handle unit configured to operate the grip member so that the regulating section is closed up to a position where the regulating section contacts the treatment section except when the receptacle contacts the treatment section.

A surgical tool includes a sheath, a probe body, a distal end portion and a proximal end portion. A probe distal end portion is provided at the distal end portion of the probe body, a jaw is rotatably supported on the distal end portion of the sheath and is engaged with the probe distal end portion. A first tubular member a fits on the proximal end portion of the sheath and extends rearward. It has an elongated slit and extends in an axial direction of the sheath. A second tubular member fits in a rear end portion of the first tubular member. A tubular driving member is slidably inserted in the sheath and rotates the jaw. A coupling member including a projection body passes through the second tubular member, includes an engaging portion which is engaged in the slit of the first tubular member.

An ultrasonic treatment device comprises a transducer unit, probe unit, and a main unit. The transducer unit comprises an ultrasonic transducer generating ultrasonic vibration in response to supply of power. The probe unit has a treatment member at a distal end thereof. The probe unit is detachably loaded to the transducer unit, and is equipped with an ultrasonic probe transmitting the ultrasonic vibration to the distal end of the treatment member when the transducer unit is loaded to the probe unit. The main unit is manually grasped by an operator. The probe unit with the transducer unit loaded thereto is detachably loaded to the main unit. The main unit has a cylindrical insert through which the ultrasonic probe is inserted to have the treatment member protruded outwardly when the probe unit is loaded. The main unit further has an outer sheath detachably covering an outer surface of the insert.

An ultrasonic surgical instrument includes an ultrasonic vibrator, a vibration transmission section, a grip member, a pad member provided at a position of the grip member which faces the treatment section, and a planar facing surface disposed on the pad member. A distal end portion of the treatment section faces the pad member, and is curved from a proximal end portion side of the treatment section toward the distal end portion side of the treatment section in a direction away from the facing surface. The pad member includes a protruding portion which is disposed on the facing surface, protrudes from the facing surface toward the distal end portion of the treatment section, and abuts on the distal end portion of the treatment section while the grip member is closed.

A surgical operating apparatus includes a sheath, a probe body which is inserted through the sheath, and in which ultrasonic vibration is configured to be transmitted, a probe distal end portion which is provided at a distal end portion of the probe body and configured to function as one of bipolar electrodes, and a jaw which is rotatably supported on a distal end portion of the sheath, has an engaging surface which is engaged with the probe distal end portion, and has a second electrode section which is the other of the bipolar electrodes, wherein the jaw includes, at a distal end portion of the engaging surface for engagement with the probe distal end portion, a distal end chip which tolerates a positional displacement relative to the probe distal end portion when the jaw is engaged with the probe distal end portion.
摘要:
A surgical operating apparatus includes an ultrasonic treatment section which performs ultrasonic treatment on a living tissue, and a high-frequency treatment section which performs high-frequency treatment on the living tissue, and includes a narrow width part which is provided on at least one of mutually opposed surfaces of a first electrode portion of a first grasping member and a second electrode portion of a second grasping member. The narrow width part is configured to be disposed at a position where the second grasping member does not easily suffer a stress due to ultrasonic vibration when the living tissue is grasped between the second grasping member and the first grasping member, and to make a distance between the mutually opposed surfaces of the first electrode portion and the second electrode portion narrower than a distance at other positions.
