Description of the Related Art For blood vessel coagulation hemostatic devices, an electrosurgical instrument of Japanese Industrial Standard (electric scalpel, JIS T-1453) is attached with an electrosurgical instrument having a main carrier frequency of 0.3 MHz to 5 MHz and a maximum output of 50 W or more. Positioned as one of the products, the bipolar electrode is widely used for microsurgery for low-power coagulation and hemostasis. This bipolar polariser has a structure in which two electrodes, an active electrode and an inactive electrode, are insulated and held on the same support part, and is provided at both ends of a bipolar type comb held by hand. Energizes only the living tissue sandwiched between the two electrodes of the constrictor tip of the mold, and the electrical invasion to the patient is limited to the local area where it is desired to coagulate, and hemostasis from blood vessels is completely achieved without damaging other tissues. It is designed so that it can be stopped. That is, the hemostatic action is performed by the coagulation of the blood vessel by the local heating caused by the high-frequency current flowing through the living tissue.

てなるものなどがあった。The material of the bipolar type concentrator (hereinafter abbreviated as “concentrator”) which has been conventionally used is made of metal such as stainless steel or titanium, or JP-A-2-634.
As in the invention of No. 49, there is one in which an electrically insulating sintered body having a large number of pores is arranged in the blood vessel holding portion and the pores are filled with a conductive material.

経済でもあった。Of these, the metal concentrator has a large thermal conductivity and tends to transmit heat easily. Therefore, the heat of the locally heated blood vessel is conversely conducted to the metal perforator side, and the tip of the perforator gradually becomes hot with use, causing charring between the metal at both tip of the perforator and the blood vessel. Is partly attached to the tip of the concentrator. As a result of this adhesive force being greater than the coagulation force between blood vessels, when the tip of the condyle is opened after coagulating blood vessels, the coagulated portion of the blood vessel is often peeled off and removed. There was a problem that it failed to stop hemostasis because it opened again. In addition, it is necessary to scrape off the adhered substances that have burnt to the surface of the abutting part (electrode) in preparation for the next use, and clean them off. Was also a big problem. Not only that, but it was also very uneconomical to prepare multiple spermatozoa for a single operation.

A water-cooled type of concentrator has been proposed, which causes the flow of water.

Description of the Related Art In the conventional blood coagulation / hemostatic device having a water-cooled concentrator described above, it was possible to prevent the living tissue from being overheated due to the high-frequency energization, which could prevent the living tissue from being damaged and attached to the tip of the constrictor. The following problems existed.

なかったりする恐れがあった。In other words, in the conventional hemostatic device for blood vessel coagulation, the jetted cooling liquid flows into other incised parts of the living body, stays in the affected area and obstructs the visual field in surgery, or the fever temperature is lowered too much. There was a risk that the vascular tissue could not be coagulated.
