温熱治療は癌を始めとする様々な疾患にその効果が期待
されている治療手技であり、加熱方法としても様々な原
理のものが提案されているが、マイクロウェーブや高周
波などの電磁波加熱が最も有望な技術として試みられて
いる。[Detailed description of the invention] Hyperthermia therapy is a therapeutic technique that is expected to be effective for various diseases including cancer, and various heating methods have been proposed, but microwave and Electromagnetic heating, such as high-frequency waves, is being tried as the most promising technology.
高周波加熱は通常二枚の金属対極板で加熱しようとする
人体部位をはさみ、これらの金属対極板間に１０ＭＮｚ
位の高周波電圧を印加し金属対極板間に流れる誘導電流
の起こすジュール熱により人体部位を加熱するものであ
る。In high-frequency heating, the human body part to be heated is usually sandwiched between two metal return electrodes, and 10 MNz is placed between these metal return electrodes.
The device heats parts of the human body by Joule heat generated by the induced current flowing between the metal counter electrodes by applying a high-frequency voltage of about 100 mL.
このような原理による加熱であるから、誘導インピーダ

大半が失なわれるという問題がある。さらにアプリケー
ターと皮膚との接触が不完全であったり、皮膚が発熱し
たりするとこのようなロスがおおきく、火傷を起こして
しまう。このような問題はアプリケーターを生体内に楯
込むことにより避けることができる。Since heating is based on this principle, there is a problem in that most of the applied energy is lost between the metal return electrode plate, which has a large inductive impedance, and the skin. Furthermore, if the contact between the applicator and the skin is incomplete or if the skin heats up, this type of loss is large, resulting in burns. Such problems can be avoided by shielding the applicator within the body.

ーを提供しようとするものである。Moreover, with the coffin-type applicator, since the applicator is placed near the cancerous tissue, the dust tissue can be efficiently heated with a small output. However, even with an in-vivo shield applicator, cooling and energization of the return electrode are necessary. However, in thermal treatment of habitual tumors, etc., it is necessary to repeat heating for 2 to 3 hours at intervals of about one week, and during this period, patients are usually engaged in social activities, so The shield-embedded applicator allows the cooling mechanism of the return electrode to be shielded together with the return electrode.The return electrode and cooling structure that are shielded inside the living body do not need to be removed because they will be used again, but the current-carrying mechanism does not need to be removed. It must be able to be connected before treatment and removed after treatment. Therefore, the present invention provides an in-vivo shield for thermotherapy in which the cooling mechanism for the return electrode embedded in the living body can be incorporated together with the return electrode, and the energization mechanism for the return electrode can be attached and detached before and after treatment. It attempts to provide a built-in applicator.
以下図示する実施例により本発明を詳細に説明する。The present invention will be explained in detail with reference to examples shown below.

。Copper pipe 3 (4th outer diameter, 3rd inner diameter) is passed through this silicone tube and screwed onto the inner surface of disk 1.The copper pipe serves as a cooling water injection and as a power conductor. Cooling water is injected into the applicator from Sekiguchi 5.The electric power from the warmer is connected to the copper pipe 3 via a conductor, and the connection 4 is a removable screw. After salting, the conductor wire is removed.As mentioned above, in Example 1, the return electrode plate is constructed with a hollow stainless steel disk 1, so that the hollow part in the return electrode plate is used as a cooling structure, and the cooling liquid is injected into the hollow part. One of the sending tubes 2 and 3 is composed of a copper pipe 3, and a power supply conductor is detachably attached to the copper pipe, so that the current supply mechanism can be easily attached and detached via the copper pipe that is the cooling structure. becomes.

A thin copper wire may be attached to the disc through the inside of the tube using the inner diameter of the tube, and a power conductor may be detachably attached to this copper wire via the connection 4 in the same manner as described above.
この場合、シリコンチューブは銅パイプ３より柔軟性が

去できることが好ましい。In this case, since the silicone tube is more flexible than the copper pipe 3, it is convenient for inserting the applicator into a deeper site. In the case of Example 1, the silicone tube 2 and copper pipe 3, which constitute the cooling structure, have to be taken out percutaneously, so care must be taken to prevent infection while the treatment is continuing. When the urinary scar disappears and heat treatment is no longer necessary, remove the screw from the copper pipe 3, which is secured with a screw, and insert the silicone tube 2 against the fixing means such as silicone adhesive between it and the disc 1. It is preferable that it can be easily removed by pulling it.

。In addition, since there are many cases where Disku is used again, it is surgically removed after confirming that the Higemanto has been completely treated. Example 2 (FIG. 2) is an idea that uses blood as the coolant. An inflow path 22 and an outflow path 23 made of an artificial blood vessel such as Gucron are sewn to a large blood vessel, and blood is circulated and cooled in a Dacron sack 21 provided with a return electrode function. To give the Dacron sack 21 the function of a counter electrode, a pure gold plate 24 is provided in the center of the sack, and a gold wire is sewn into the Dacron sack 21.

ることも可能にする効果がある。Another advantage of using blood for cooling is that there is no need to send cooling water from outside the body. As a modification of the second embodiment, it is easy to think of a method in which a hollow disk of solid metal is used instead of the Dacron sack, or a method in which stainless steel coated with pyrolite carbon is used. As described above, according to the present invention, a good conductive return electrode plate having a wide area that is shielded in a living body, and a cooling hollow portion provided inside or on the outer periphery of the return electrode plate that is inserted into a living body together with the return electrode plate. , an in-vivo bath for thermotherapy, comprising a cooling circulation structure that circulates a cooling liquid in the hollow part, and an energization structure that is detachably connected to the shielded return electrode plate via the cooling structure and supplies electric power. Since it has the structure of a built-in applicator, the cooling hollow part of the return electrode plate and the cooling circulation mechanism can be shielded into the living body together with the return electrode plate, while the current-carrying structure is connected to the Dacron sack, which is the cooling hollow part, and the cooling circulation mechanism. It has the effect of being able to be connected before treatment and removed after treatment through a cooling structure made of copper pipes, etc., and is used for heat treatment of habitual tumors, etc., for 2 to 3 hours at intervals of about a week. Repeated heating also has the effect of allowing patients to engage in social activities during this time.
