Embodiment Construction

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing ultrasonic scissors with electrocautery as a surgical instrument according to the first embodiment of the present invention. In addition, FIG. 2 is a block diagram showing the overall configuration of a system including the surgical instrument in FIG. 1 .

[0022] First, referring to FIG. 2, the structure of the whole system is demonstrated.

[0023] The ultrasonic surgical scissors 4 with electric knife are connected to the ultrasonic output device 2 through the ultrasonic cable 3 . An ultrasonic foot switch 1 is connected to the ultrasonic output device 2 . The ultrasonic foot switch 1 sends on / off (ON / OFF) instructions of the ultrasonic output to the ultrasonic output device 2 according to the user's operation. The ultrasonic output device 2 generates ultrasonic output according to the ON / OFF instruction sent by the ul...

Abstract

The present invention provides a surgical instrument, which has: an ultrasonic vibrator, which generates ultrasonic vibration; an ultrasonic probe, which transmits the ultrasonic vibration generated by the ultrasonic vibrator to its front end; a clamping member, which is opposite to the front end of the ultrasonic probe Move between the close position and the distant position, and be configured to clamp the living tissue of the treatment object between the clamping part and the front end of the ultrasonic probe; the conductive part is arranged on the above-mentioned clamping part, and the a high-frequency current is supplied to the above-mentioned living tissue, and is made of a conductive material; and a non-conductive member, which is provided on the clamping member between the above-mentioned conductive member and the above-mentioned ultrasonic probe, so as to prevent the contact between the above-mentioned conductive member and the above-mentioned ultrasonic probe. contact between them, and is formed in a shape that exposes a part of one surface of the above-mentioned conductive member on the side of the ultrasonic probe, and is made of a non-conductive material, and the surgical instrument can effectively conduct high-frequency current to the living tissue. power ups.

Description

technical field [0001] The present invention relates to a surgical instrument capable of performing treatment with high-frequency current in addition to the treatment of resection or coagulation of living tissue using ultrasonic vibration. Background technique [0002] Surgical instruments have been developed in which, by inserting a long and thin insertion portion into a body cavity, various treatments can be performed under endoscopic observation by using an endoscope for observing internal organs of the body cavity, etc., as required. [0003] For example, Japanese Patent Application Laid-Open No. 2004-216180 (hereinafter referred to as Document 1) discloses a combination of an ultrasonic coagulation and incision device and an electric knife. With regard to the device in Document 1, the treatment part is composed of a clamping member and a probe, and the tissue is clamped by the two components and ultrasonically vibrated by the probe, thereby coagulating and incising the ...
