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) includes a pair of forceps elements (forceps cups (1)) constituted of a conductive metal and configured to serve as high-frequency electrodes and configured to be able to change into a state where front portions of the pair of forceps cups (1) are open, and a state where the pair of forceps cups (1) are close. A sawtooth portion (15) having a plurality of concavo-convex structures which constitute a sawtooth-shape is provided on at least one of respective closing-side surfaces (17) of the pair of forceps cups (1). The sawtooth portion (15) is provided with an electrically insulative coating over its bottom portion (21), but not on a top portion (22) thereof, and hence the top portion (22) is 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...
