Problems solved by technology

[0002] Endoscopic hemostatic forceps apply high-frequency current to a pair of high-frequency electrodes clamping biological tissue to burn and coagulate the biological tissue, but when the area of ​​the high-frequency electrode in contact with the biological tissue is large, the contact part is heated It takes time for the temperature to produce a hemostatic effect
Therefore, a wide range of deep burns are caused inside the living tissue, resulting in useless tissue destruction, and the much-anticipated hemostatic effect is not satisfactory.

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

[0029] figure 1 It is a perspective view showing the tip portion of the endoscopic high-frequency hemostatic forceps (hemostatic forceps 20 ) according to the first embodiment of the present invention.

[0030] First, the hemostatic forceps 20 of this embodiment will be briefly described.

[0031] The hemostatic forceps 20 are provided with a pair of forceps heads (cups 1 ) made of conductive metal facing forward and serving as high-frequency electrodes, and the pair of forceps heads (cups 1 ) can be opened and closed mutually.

[0032] A plurality of serrated unevennesses 15 are formed on at least one of the opposing closing direction surfaces 17 of the pair of pliers cups 1 . An electrically insulating coating is applied to the bottom 21 of the serrated unevenness 15 , and the top 22 of the serrated unevenness 15 is a surface without electrical insulat...

Abstract

A hemostatic forceps (20) is provided with a pair of forceps prongs (forceps cups (1)) consisting of electrically conductive metal and serving as high-frequency electrodes, and the pair of forceps prongs extend forward so as to be able to be opened and closed relative to each other. Either one and/or the other of facing closing surfaces (17) of the forceps cups (1) has formed thereon sawtooth-like protrusions and recesses (15). In the sawtooth-like protrusions and recesses (15), the roots (21) are subjected to electrically insulative coating and the crests (22) are not subjected to electrically insulative coating but are electrically conductive.

Description

technical field [0001] The invention relates to an endoscope high-frequency hemostatic forceps for hemostasis of biological tissues. Background technique [0002] Endoscopic hemostatic forceps apply high-frequency current to a pair of high-frequency electrodes clamping biological tissue to burn and coagulate the biological tissue, but when the area of ​​the high-frequency electrode in contact with the biological tissue is large, the contact part is heated It takes time for the temperature to produce a hemostatic effect. Therefore, a wide range of deep burns is caused inside the living tissue to cause useless tissue destruction, and the much-anticipated hemostatic effect is not satisfactory. In this regard, there is a clamp-type high-frequency therapeutic apparatus, which is provided with a pair of clamp cups facing forward, which are made of conductive metal used as high-frequency electrodes. The pair of clamp cups can be freely opened and closed, and only The conductive m...
