Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high frequency conducive heating thermal therapy applicator.

Conventional Techniques There is a method in which an applicator is inserted into parts of the living body that are open to the outside world, such as the rectum and esophagus, nasal passages, ears, eyes, mouth, uterus, and trachea, and heated.

This advantage of the insertion heating type is thought to be due to the following problems with body surface applicators and shield-embedded applicators. In other words, when adding salt using a body surface applicator,
The rectum, abdomen, prostate, uterus, etc. are compressed by the pelvis,
Although induction heating from the body surface is difficult, and heating deep parts is not as good as with a gutter-type applicator,
If you can access the affected area using a suitable intestinal tract,
This is because it can be heated with a small amount of power, has higher selectivity, reduces the risk of burns, and requires less strain on the equipment.

However, as with the electrode described in Utility Model Application Publication No. 11729 of 1930, a mechanism for cooling the electrode is required, and if the electrode is directly cooled, the cooling area becomes small and the amount of cooling fluid is small. Therefore, it became necessary to use a temperature measuring device, and a mechanism using a complicated elastic body was required to provide the temperature measuring device, as described in Showa 12 Utility Model Application Publication No. 945.

Problems to be Solved by the Invention If both of these are performed at the same time, if an electrode cooling mechanism is provided, a thermometer cannot be inserted, and if a thermometer insertion mechanism is provided, an electrode cooling mechanism cannot be provided.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a high frequency induction heating type thermal therapy applicator that solves the problems of the prior art by providing a larger cooling surface and a larger amount of cooling fluid. Means for Solving the Problems In other words, the present invention provides an elastic sac that is inserted into the body through an opening in the human body such as the intestine orally, and that is expanded to the wall of the lumen after being inserted into the human body. A pipe member for circulating cooling fluid to enlarge the sac.

Therefore, according to the configuration of the present invention, a large amount of cooling fluid can be used by circulating the cooling fluid in the elastic sac, and by regulating the temperature and amount of this cooling fluid, the risk of burns can be prevented. This eliminates the need to use a conventional thermometer, and allows for more accurate and reliable temperature control, allowing for effective thermal treatment.Furthermore, the electrodes can be shaped to suit the application. can.

Example The present invention will be explained below according to the embodiments shown in the drawings.

Figure 1 shows a rectal applicator with an outer diameter of 10 ribs. ,
Cut a piece of copper/guipoo on the inner diameter 9 side to a length, and fit a rubber stopper 2 on the top of the tip to block the pipe and ease the pain during insertion.In addition, use an ultra-thin rubber sack 5. It is designed so that it will not be exposed to.

The rubber sack 5 is fixed to the copper pipe 1 with a rubber thread (not shown) beyond a ring-shaped stopper 6 provided one rib from the other end of the copper pipe.

Make a hole on the 5th side about an io willow below the tip of the copper pipe and use it as the cooling water inlet 3, and connect the copper pipe with the outer diameter of the 5th side and the inner diameter of the 4th side in an inverted L-shape up to the inlet. Insert it and weld it to the cooling water inlet. A fifth side outlet 4 is provided above the IJ ring stopper 6 from the other end of the copper pipe to circulate cooling water. Furthermore, a conductive wire 7 is soldered to the inner wall of the copper pipe to use the copper/pipu as an electrode. In addition, PVC tube 8 with an inner diameter of 5 and an outer diameter of 6 is added to the inner diameter of 1.
The applicator is completed by liquid-tightly placing it in a PVC tube 9 with an outer diameter of 12 yen on the 0 side. For example, when this applicator is inserted into the rectum, the protrusion 6 forms a corner of the town gate, and when cooling water is injected, the sac 5 swells to fit the shape of the rectum, and the pump injection pressure and rubber elastic force are balanced. The sac 5 is brought into close contact with the rectal wall. Second
The figure shows another embodiment, showing an esophageal applicator.

This applicator is a fully flexible version of the rectal applicator. The stopper 11 is made of rubber as in the first embodiment. Is the applicator electrode an outer diameter of 8 willow? , a copper cylinder 12 with a thickness of 1 mm and a dense copper coil 13
is connected. The copper conducting wire 14 is placed inside a PVC tube 15 on the fifth outer diameter side and the fourth inner diameter leg, and this PVC tube serves as a coolant inlet. The other end of the steel coil 13 is the stopper 1
Fix it at 6. An extremely thin rubber body is placed between the stopper 11 and the stopper 16, and finally, a PVC tube 18 with an inner diameter of 8 yen and an outer side of the tube is connected to form a coolant outflow hole.
However, as a result of further pursuing the present invention, it was found that it is preferable to use a conductive rubber sack as an electrode, as shown in FIG.

The conductive rubber sack is formed by thermally bonding a fine, sparse, stretchable metal mesh 21 onto conductive rubber 22. If such a structure is not adopted, the connection part will burn out if the conductor is connected to the rubber sack as it is. A conductive rubber sac can also be made by applying silver plating to conductive rubber and soldering a conductive wire thereto with a wide contact surface. In this embodiment, 23 is a copper pipe on the third side of the outer cover and the second side of the inner diameter, the tip of which is sealed with a rubber stopper 25, and a coolant injection hole is provided one inch below the tip.

24 is a conductive rubber sack with a stopper 27 attached to the bottom of the rubber sack, and the stopper 27 has an outflow hole and a pipe 2.
9 is provided and a conducting wire 28 is connected thereto. Effects of the Invention As described above, according to the configuration of the present invention, the cooling area of the electrode can be increased and a large amount of cooling fluid can be used, which not only prevents dangers such as burns but also reduces the amount of cooling fluid. Desired heat treatment can be easily achieved by adjusting the temperature and amount.
