Embodiment Construction

[0073] 1 to 49 show a first embodiment of the present invention. FIG. 1 is a schematic diagram showing the overall configuration of a hand-held device 1 of an ultrasonic treatment device according to the present embodiment. The ultrasonic treatment device according to this embodiment is an ultrasonic coagulation and incision treatment device that uses ultrasonic waves to perform treatments such as incision, excision, or coagulation of living tissue, and can also perform high-frequency treatment.

[0074] As shown in FIG. 2 , the handset 1 has four units of a vibrator unit 2 , a probe unit (probe unit) 3 , an operation unit (operation unit) 4 , and a sheath unit (sheath unit) 5 . These four units are connected together so that they can be attached and detached separately.

[0075] A vibrator 6 (refer to FIG. 36 ), which will be described later, for generating ultrasonic vibrations by a piezoelectric element that converts electric current into ultrasonic vibrations is incorpora...

Abstract

A surgical operating apparatus includes an ultrasonic transducer (6) which generates ultrasonic vibration, a transducer cover (7) including a storing section (211) which stores the ultrasonic transducer (6), electric contact portions (131, 132, 133) provided on an outer peripheral surface of a distal end portion of the transducer cover (7), and insulative projection portions (123a,124a,125a) whichis provided at a distal end portion of the transducer cover (7) and projects more radially outward than an outer peripheral surface of the electric contact portions (131, 132, 133).

Description

technical field [0001] The present invention relates to a surgical device capable of performing treatments such as incision, excision, or coagulation of living tissue by using composite energy of ultrasound and high frequency, and also capable of high frequency treatment. 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. 2004-154331 discloses (Patent Document 1), the ultrasonic processing apparatus described in Japanese Patent Laid-Open No. 2003-339731 (Patent Document 2) and the like. [0003] The aforementioned Patent Document 1 discloses an ultrasonic treatment device having a structure in which an ultrasonic probe of a vibrator unit and a vibration transmission member are rotatable with respect to an operation unit. ...
