Surgical operating apparatus

Abstract

A surgical operating apparatus includes a sheath having a distal end portion and a proximal end portion; a shaft-shaped probe body which is inserted in the sheath and has a distal end portion and a proximal end portion, and in which ultrasonic vibration is transmitted; a jaw which is rotatably supported on the distal end portion of the sheath and has a first electrode section which is one of bipolar electrodes; a probe distal end portion which is provided at the distal end portion of the probe body, is engaged with the jaw, and constitutes a second electrode section which is the other of the bipolar electrodes; and a driving member including a tubular body section, which is inserted in the sheath slidably in an axial direction of the sheath, and an operation section which is provided on a distal end side of the body section and has a connection section for connection to the jaw, the driving member rotating the jaw by a sliding operation of the body section, wherein a tube body of the body section has, on an inner peripheral surface side thereof, an insulation tube which effects electrical insulation between the probe body and the body section, and the insulation tube has a projection portion which projects forward of the body section.

Description

technical field [0001] The present invention relates to a surgical device capable of performing high-frequency treatment while performing treatments such as incision, excision, or coagulation of living tissue by using composite energy of ultrasonic waves and high-frequency. Background technique [0002] Generally speaking, as an example of an ultrasonic treatment device that can perform high-frequency treatment while using ultrasonic waves to perform treatments such as incision, resection, or coagulation of living tissue, for example, Japanese Patent Application Laid-Open No. 2004-33342 (Patent Document 1) described ultrasonic treatment device. [0003] The operation part on the hand side of the device is connected to the base end part of the elongated insertion part. An ultrasonic vibrator that generates ultrasonic vibrations is disposed on the operating portion. A treatment unit for treating living tissue is arranged at the distal end of the insertion unit. [0004] The...

Problems solved by technology

Therefore, due to the bending of the probe tip at this time, the probe tip comes into contact with the tip of the sheath, and the probe tip may be damaged.

In addition, during high-frequency treatment, if the tip of the probe is in contact with the tip of the sheath due to the bending of the tip of the probe, a short circuit may occur, sparks may occur, and high-frequency treatment itself may become difficult.
