Description

[Detailed description of the invention] Technical field The present invention relates to an energized path breaking device.

TECHNICAL BACKGROUND It is known that various scientific, physical, and physiological changes occur when direct current, including pulsed current, is applied to biological parts. These changes occur because the living body is a gel body whose main component is physiological saline. Therefore,
Such changes can be used to treat diseases, particularly the destruction of cancerous tumors. Is this kind of tumor destruction currently occurring? Although some parts are still under investigation, I)l-1 near the electrode
By making active groups such as ions, OCβ-ions, active oxygen ions, active hydrogen ions, etc. near the electrode, the g 4
It is possible to destroy compositions up to about am, and it is also possible to selectively destroy ship cells by adjusting the applied current. Therefore, we inserted two platinum wires with a diameter of Q, about 3nV into a tumor in a living body, and passed a direct current between these two wires to cause electrolysis and destroy the tumor. There is.

However, in this treatment, a large amount of gas such as hydrogen is generated by electrolysis, and if this gas enters the blood vessels, it can cause blood clots, and if it enters the lungs, it can cause pneumothorax, which can lead to death of the patient. As described above, conventional platinum electrodes have the disadvantage that they have limitations such as discontinuation of treatment due to generated gas and termination of treatment due to tissue degeneration, and are unable to fully demonstrate their power against large tumors.

OBJECT OF THE INVENTION The present invention aims to eliminate such conventional corner points.
It is an object of the present invention to provide a current-carrying layer destruction device that continuously removes gas generated by electrolysis using a current-carrying liquid and is also suitable for large-scale Ill ulcers.

The configuration of the invention, that is, the configuration of Mizumoto Ill, includes an electrode and an ion exchanger 1! near the electrode. A rubber balloon having a recessed wall and a conductive liquid passage for discharging gas generated by electrolysis between the electrode and the conductive liquid, wherein the ion exchange membrane partition wall is made of an ion exchange membrane. It is characterized by

Effects of the Invention Therefore, according to the configuration of the present invention, the gas generated between the electrode and the conductive liquid is discharged from the body by the conductive liquid through the passage of the conductive liquid, so that the gas generated by electrolysis is eliminated. Treatment can be performed without side effects such as blood clots and pneumothorax caused by gas, and the use of an ion-selective balloon has the following effects.

1. Because the ion generation area became larger, the range of protein denaturation caused by I)H fluctuation near the electrode became larger, and it became possible to destroy up to about 20111 from the balloon surface.

2. The range of damage caused by DC disease is 5 cl from the balloon surface.
, so even large tumors can be destroyed.

3. By inflating the balloon to match the size of the lumen, its range of applications has expanded, including for uterine cancer.

4. The amount of electricity that can be injected until the end of treatment due to tissue degeneration and gas generation has increased significantly, and more than 10 times more coulombs can be injected than in the past. Therefore, the therapeutic effect increases dramatically.

That is, when the balloon diameter is 2 cmk-M, the destruction range due to protein denaturation is (2+2)3π/(2)3=8 times, and the range of direct current cancer destruction is (5+2)3π,/( 5) 3π becomes approximately 2.8 times.

Example The invention will be explained below with reference to the embodiments shown in the drawings.

The drawings are partially enlarged for explanation purposes, but the electric 4! I
i1 is a platinum tube with an outer diameter of 150μ, an inner diameter of 100μ, and a length of 80CI, and a power supply cord P is glued to a part of the tube. The electrode 1 has an opening for injecting physiological saline at one end thereof, and this opening is connected to a hose of a physiological saline supply device (not shown) at a fitting portion 2 thereof.

Further, the lower end of the electrode 1 has an opening for discharging physiological saline, and an ion exchange balloon 3 made of rubber and made of an ion exchange membrane is disposed opposite to this discharge opening.

The ion exchange balloon 3 is fixed to a Teflon tube 4 into which the electrode 1 is inserted, forming a passage for guiding the physiological saline discharged from the electrode I. 5. Introduce physiological saline and cover. This annular portion 5 is also provided with a Luer lock 6,
Connected to a saline drain hose (not shown). The small diameter portion of the Teflon tube 4 has an outer diameter of 2.1 mm and an inner diameter of 1.5111I1. And the length is 7Qcm.

Next, how to use the above device will be explained.

First, the Teflon tube 4 that constitutes the physiological saline passage
The small-diameter part below the annular part 5 is inserted, and a bisectable conduit having an inner diameter of 1 is attached to the tip of the JJ nail and inserted into the affected area in the living body, and the completed part is removed. Then, insert the small diameter part of the Teflon tube of the current-carrying layer destruction device into the conduit.

Therefore, the ion exchange balloon part is located near the affected area in the living body, such as a tumor existing in the lumen of rectal cancer or a large diameter blood vessel in this example. Once the tumor is reached and the conduit is cut in two and removed, a current-carrying layer breaking device is installed.

In this state, physiological saline is injected from the luer lock part 21 of the electrode 1 and a high-speed flow of physiological saline is applied to the ion exchange balloon 3.
and give it to the passage where Teflon tube 4 is purchased, and electrically 4~l
Power on. When electrolysis occurs between the Raijin 1 and the physiological saline, gas such as hydrogen is generated.This gas is transferred to the 1■-shaped part 5 at the top of the Teflon duplex 4 by the flow of the physiological saline.
When asked, the electrode part J is leaked out. Active ions generated from the electrode 1 pass through the ion exchange balloon 3 and are diffused into the living body, destroying cancer cells in the affected area.
