明者が行った。[Prior Art] Methods of cauterizing or heating and coagulating living tissue using high-frequency current have been used in surgical operations and the like for a long time. For example, for burning out the affected area within the body cavity,
Japanese Patent Application Laid-Open No. 62-211060 discloses a method for heating and coagulating living tissue for the purpose of hemostasis, and Japanese Patent Application Laid-Open No. 57-1
It is described in No. 85847, JP-A No. 63-24933, etc. In addition, the present inventor has recently proposed that a needle-shaped working electrode is inserted into the skin and a high-frequency current is applied to heat and coagulate only the targeted subcutaneous tissue without leaving any scars on the surface skin.

［発明が解決しようとする問題点］
しかしながら、特開昭６２−２１１０６０号の発明は、
電極を直接患部に接触させて、強力な高周波電流を流し
て患部を焼き切るものである。(Refer to JP-A-59-114147) [Problems to be solved by the invention] However, the invention of JP-A-62-211060
Electrodes are brought into direct contact with the affected area and a powerful high-frequency current is applied to burn the affected area.

せ凝固させて、止血等を行なっている。このように直接
患部に電極を接触させるためには、患部を切開して露出
させなければならない。The invention disclosed in Japanese Patent Application Laid-Open No. 63-24933 similarly involves bringing an electrode into direct contact with the affected area and passing a high-frequency current through it to generate heat and coagulate the affected area to stop bleeding. In order to bring the electrode into direct contact with the affected area in this way, the affected area must be incised and exposed.

入しなければならない。The invention disclosed in JP-A-57-185847 heats and coagulates the affected area by passing a high-frequency current through the affected area through a conductive fluid. In this method, the electrodes are not brought into direct contact with the affected area, but in order to bring the fluid into direct contact with the affected area, a tube for supplying the fluid must be inserted deeply into the body cavity.

また、作用電極が針状をなしているので、その治療範囲
が極限され、植毛以外の目的に使用する時は、非常に能
率が悪いという欠点がある。The idea of Utility Model Application Publication No. 59-114147 is to apply an electrically insulating coating to the surface of the working electrode, leaving only the tip of the needle-like working electrode, to prevent high-frequency current from flowing to the skin surface, and to prevent scarring on the skin surface. The aim is to heat and coagulate only the target subcutaneous tissue without leaving behind any residual tissue. However, this method requires a needle-like working electrode to be penetrated into the skin.
Furthermore, since the working electrode is needle-shaped, its treatment range is limited, and when used for purposes other than hair transplantation, it has the disadvantage of being very inefficient.
本発明は、電極を直接患者の体内に挿入ないしは突き刺
さないで、皮膚の上から間接的に加熱することによって
、皮膚の下の組織を凝固させるものである。The present invention coagulates tissue under the skin by indirectly heating the skin from above, without directly inserting or piercing the electrode into the patient's body.
一般的にいって、高周波加熱凝固を起こさせる場合は、
０．５〜１０ＭＩＩｚ 、好ましくは２．５Ｍｌ１ｚ以
下の周波数の高周波を用い、作用電極より、人体を挟ん
でその対極としての分散型電極に電流を流す。Generally speaking, when causing high frequency heating coagulation,
Using a high frequency wave of 0.5 to 10 MIIz, preferably 2.5 Ml1z or less, a current is passed from a working electrode to a dispersion type electrode serving as a counter electrode across the human body.
しかし、皮膚の上に電極を当てて高周波電流を流すと、
高周波電流によるジュール熱によって皮膚の下の組織を
凝固させることはできても、当然皮膚そのものも加熱さ
れ、いわゆる、皮膚熱傷を起こす。However, when electrodes are placed on the skin and a high-frequency current is applied,
Although it is possible to coagulate the tissue under the skin using Joule heat generated by high-frequency current, the skin itself is also heated, causing so-called skin burns.
そこで、本発明は、表面の皮膚には何等損傷を与えない
で、皮膚の下の組織のみを選択的に加熱凝固させる高周
波加熱凝固装置用の電極構造体を提供することを第１の
目的とするものである。Therefore, the first object of the present invention is to provide an electrode structure for a high-frequency heating coagulation device that selectively heats and coagulates only the tissue under the skin without causing any damage to the surface skin. It is something to do.
次に、本発明は、表面の皮膚には何等損傷を与えないで
、皮膚の下の比較的広範囲の患部を一度に処理できるよ
うにした高周波加熱凝固装置用の電極構造体を提供する
ことを第２の目的とするものである。Next, the present invention aims to provide an electrode structure for a high-frequency heating coagulation device that can treat a relatively wide range of affected areas under the skin at once without causing any damage to the surface skin. This is the second purpose.
［問題点を解決するための手段］

口と冷却液を回収するための還流口とを設けたことを要
旨とするものである。[Means for Solving the Problems] The electrode structure for a high-frequency heating coagulation device of the present invention has a connection terminal for connecting to a high-frequency current generator on the back surface,
In a flat electrode having a working surface, an annular barrier for stopping liquid is provided along the edge of the working surface, and an annular barrier for stopping liquid is provided on the flat electrode, between the working surface and the annular barrier for stopping liquid. The gist is that an outlet for supplying a cooling liquid into the enclosed space and a reflux opening for recovering the cooling liquid are provided.

用表面と液止め用の環状の障壁および人体皮膚とに囲ま
れた空間に供給する。In use, the connection terminal of this electrode structure is connected to a high frequency current generator, and the coolant supply/discharge mechanism of the electrode structure is connected to a conductive coolant supply source via a pipe. Then, the liquid-stopping annular barrier provided on the flat electrode of the electrode structure is pressed onto the skin of the affected area of the human body, and the cooling liquid is applied to the working surface from the cooling medium supply source through the cooling liquid supply mechanism. It is supplied to the space surrounded by the annular barrier for liquid stop and the human skin.

周波電流を供給すれば、高周波電流は、平面電極の作用
表面より導電性の冷却液を通じて流れ、さらに、皮膚を
通して体内に流れ、皮膚および皮下組織を加熱する。If a high-frequency current is supplied from the high-frequency current generator through the connection terminal in this state, the high-frequency current will flow from the working surface of the flat electrode through the conductive cooling liquid, and then flow into the body through the skin, causing the skin and subcutaneous tissue to flow. heat up.
しかしながら、皮膚の表面は絶えず冷却液が循環して冷
却されているので、表面の皮膚に熱傷を負わせないで、
一定の深さの皮下組織のみを選択的に加熱凝固させるこ
とができる。However, since the surface of the skin is constantly cooled by the circulation of cooling fluid, it is possible to avoid causing burns to the skin on the surface.
It is possible to selectively heat and coagulate only subcutaneous tissue at a certain depth.
導電性の冷却液としては水、塩水、エチレングリコール

を循環させればよい。そのためには、水タンクの中に氷
を入れ、循環ポンプで水を循環させるように構成すれば
よい。As the conductive coolant, water, salt water, an aqueous solution of ethylene glycol, etc. are used. Since the temperature of the cooling liquid is approximately 0 to 10°C, it is sufficient to circulate water or salt water cooled with ice. To do this, ice can be placed in a water tank and a circulation pump can be used to circulate the water.
冷却液の導入の方法については平面電極の周囲数箇所に
設けた流出口から冷却液を外部に流出させ、平面電極の
中央の還流口から回収す方法と、その反対に平面電極の
中央の流出口から外部に噴出させ、平面電極の周囲数箇
所に設けた還流口から回収する方法の２通が考えられる
。There are two ways to introduce the coolant: one method is to let the coolant flow out from the outlet holes provided at several places around the flat electrode, and collect it from the reflux opening in the center of the flat electrode, and the other way is to let the coolant flow out through the outlet holes provided at several places around the flat electrode. There are two possible methods: ejecting it to the outside from the outlet and recovering it from the reflux ports provided at several locations around the planar electrode.
このいずれの方法でもよいが、平面電極の縁周部に沿っ
た部分が過熱されやすいので、前者の方が望ましい。Although either of these methods may be used, the former is preferable because the portion along the edge of the planar electrode is likely to be overheated.
いずれにせよ、平面電極の周囲数箇所に設けた貫通孔か
ら冷却液を給排水するためには平面電極の裏面に冷却液
チャンバーを設けることが望ましい。In any case, it is desirable to provide a cooling liquid chamber on the back surface of the flat electrode in order to supply and drain the cooling liquid from through holes provided at several locations around the flat electrode.

It is determined by the purpose of use of this electrode structure and the degree of difficulty in manufacturing.
最も普通の形状は円形である。しかし、静脈狽のように
患部が縦に細長い場合は楕円形や長方形が用いられる。The most common shape is circular. However, when the affected area is vertically long and narrow, such as in cases of phlegmon, an oval or rectangular shape is used.
また、目の下の脂肪を取る場合等は、半円形、三か月形
、場合によっては、三角形、台形なども用いられるであ
ろう。In addition, when removing fat under the eyes, a semicircular shape, a crescent shape, and in some cases a triangular shape or a trapezoid shape may be used.
いずれにせよ、患部の形状およびサイズに合わせて作用
