ッチ４を介して高周波電源５に接続されている。``Prior Art'' A surgical hemostasis device using electrocautery is explained with reference to FIG. At the tips of the metal bodies 1, 1, electrodes 3, 5 made of an iron-based alloy such as stainless steel and having sharp tips are integrally attached by brazing. The base ends of the rod-shaped metal bodies 1, 1 are connected to a high frequency power source 5 via a switch 4.

ている部分の生体組織６が焼灼されて止血する。When performing hemostasis during a surgical operation, the electrodes 3 and 5 are applied to the living tissue 6 while sandwiching the part of the living tissue 6 where bleeding should be stopped.
When the switch 4 is closed and a high frequency current of, for example, 151 MHz is discharged to the living tissue, the living tissue 6 in the area between the tips of the electrodes 3 and 5 is cauterized to stop bleeding.

た。"Problems to be Solved by the Invention" When cauterizing living tissue 6 to stop bleeding with electrodes 3 and 3 made of conventional iron-based alloys, for example, stainless steel, the living tissue 6 does not touch the electrode 3 during ablation. It is easy to adhere to the electrode 5, which causes the discharge to stop and the ablation to be interrupted.
, 3, there was also a risk of peeling off the living tissue 6 between them. When observing the electrode 3 to which the biological tissue 6 was attached during aspiration, a carbonized layer was observed between the biological tissue 6 and the electrode 3, indicating that the material of the electrode 3 and the carbon in the biological tissue 6 reacted during discharge. It has been found that living tissue adheres to the electrode 3 using it as a medium.

装置を提供することを目的とするものである。The object of the present invention is to develop a copper alloy as an electrode material that is less reactive with carbon, and to provide a surgical hemostasis device to which biological tissue does not adhere during ablation.
