【発明の詳細な説明】 ［発明の目的１ （産業上の利用分野） 本発明は、生体内の１１吉相ｒＣ８破壊するための加熱
治療器に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention 1 (Field of Industrial Application) The present invention relates to a heat treatment device for destroying the 11-auspicious phase rC8 in a living body.

（従来の技術） 癌等の生体内の有害組織を生体内において破壊するため
の手法として被破壊組織のみを選択的に長時間加熱する
方法（「ハイパーサーミャ」と称される）がある。(Prior Art) As a method for destroying harmful tissue in a living body such as cancer, there is a method (referred to as "hyperthermia") in which only the tissue to be destroyed is selectively heated for a long time.

を損傷してしまう危険もめる。その上加熱温度を長時間
制御することも容易ではない。Conventionally, microwaves, focused ultrasound, etc. have been used as a means of selectively heating only the tissue to be destroyed within the living body, but both of these methods apply energy from outside the living body to localize the targeted tissue within the living body. It is very difficult to accurately concentrate energy only on the area to be destroyed, which has a diameter of several meters to several crons. Therefore, there is a risk of damaging parts other than the desired part to be destroyed. Moreover, it is not easy to control the heating temperature for a long time.

（発明が解決しようとする問題点） このように従来の加熱治療器においては、所望の被破壊
部位のみを正確に破壊するのが困難でおるという問題が
ある。(Problems to be Solved by the Invention) As described above, in the conventional heat treatment device, there is a problem in that it is difficult to accurately destroy only the desired region to be destroyed.

本発明は以上の問題に対辺してなされたもので、所望の
被破壊部位のみを正確に破壊することができる加熱治療
器を提供することを目的とするものである。The present invention was made in response to the above problems, and an object of the present invention is to provide a heat treatment device that can accurately destroy only a desired region to be destroyed.

A catheter that can be inserted into a living body cavity through the forceps hole of this endoscope and has a heating element at its tip and a liquid introduction hole around its periphery; It is characterized by comprising a balloon that can be expanded and contracted by being heated by a heating element supplied from an introduction hole.

Next, while a liquid such as water is supplied into the balloon, the liquid is heated by a heating element to bring the balloon into contact with the site to be destroyed, thereby destroying harmful tissue at the site. Therefore, only the area to be destroyed can be accurately destroyed, and by expanding and contracting the balloon, destruction can be performed in accordance with the size of the area to be destroyed.

The inside of the living body cavity can be observed through the viewing section 4. A catheter 6 is inserted into the forceps hole 5 of the endoscope 1, and a heating element such as a positive temperature coefficient thermistor (hereinafter referred to as PTC) 7 is provided at the tip of the catheter 6. A pair of liquid introduction holes 8a and 3b are provided around the periphery. The catheter 6 has a bore 9 therein, through which a guide wire (not shown) and feeder lines 10a, 10 are connected to the PTC 7.
b is connected to the power source 11. A balloon 12 made of rubber, for example, is provided to cover the distal end and surrounding area of the catheter 6, and this balloon 12 is connected to the liquid introduction hole 8.
A liquid such as water is supplied from a water source 13 via a and 3b. As these catheter 6 and balloon 12, commercially available balloon catheters can be used. The endoscope 1 and catheter 6 are made of flexible members so that they can be freely inserted into a living body cavity.

前記ＰＴＣ７は、周囲温度が下がった場合に電流が増加

的に周囲温度を一定にするような温度補償動作を行う。The PTC 7 performs a temperature compensation operation in which the current increases when the ambient temperature falls, and conversely, the current decreases when the ambient temperature rises to automatically keep the ambient temperature constant.

できる。As shown in FIG. 3, if there is a harmful tissue, for example, cancer tissue 4, 15 in a certain position in the body cavity 14, for example, in the gallbladder, what happens inside? Ii! Insert it close to the cancerous tissue 15 while being careful. At this time, a catheter 6 is guided through a guide wire (not shown) through the forceps hole 5 of the endoscope 1, and the balloon 12 and PH
10 is brought close to or in contact with the cancerous tissue 15. Next, or in advance, water is supplied into the balloon 12 from the water source 13 through the liquid introduction holes 3a, 3b, and this water is heated by the PTC 7. In the case of water, it can be heated to boiling point of 100'C.

これによってバルーン１２は伸長することにより癌組織
１５に密着しこれを加熱する。As a result, the balloon 12 expands and comes into close contact with the cancerous tissue 15 to heat it.

ＰＴＣ７の略一定となる発熱温度は素子材料の組成によ
って定まるキュリ一温度によりわずかに高い温度であり
、キュリ一温度は例えばＯ′Ｃ前俊がら３００　’Ｃ前
後までの広範囲に選定することかできる。The almost constant exothermic temperature of PTC7 is slightly higher than the Curie temperature, which is determined by the composition of the element material, and the Curie temperature can be selected over a wide range, for example, from O'C to around 300'C. .

従って予め定めた加熱温度に合った素子を選定すること
により、バルーン１２と密着している特定部位のみを予
め選定した一定温度で長時間加熱することが可能となる
。Therefore, by selecting an element suitable for a predetermined heating temperature, it is possible to heat only a specific portion that is in close contact with the balloon 12 at a predetermined constant temperature for a long period of time.

一般に癌組織の破壊には、癌組、鯖の温度を例えば数日

Also, biological cavity 1
If the inside of 4 is closed by cancerous tissue, use a high-temperature PTC to burn off the closed part, and then, for example, 4
It is preferable to use a PTC that maintains the temperature at 3±1°C.

Since it is guided to the desired part to be destroyed, only the part to be destroyed can be accurately destroyed.

Ｉ熱効果が低下することはない。FIG. 4 shows another embodiment of the present invention, particularly for cancer patients,
This shows an example where the distance W between the peaks 15A and 15B is large. In such a case, without the balloon 12, the heat of the PTC 7 would not be directly transmitted to the cancer tissues 15A, 15B, but would be transmitted via bile, etc., so there is a risk that the heating effect would be reduced and the purpose could not be achieved. In this respect, according to this embodiment, since the heat of PTC7 can be transferred through the liquid to extend the balloon]2, h'
The I-thermal effect is not reduced.
