Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermotherapy device for treating tumors with heat.

[Prior Art] Cancer (tumor) treatment requires 1. Heat treatment is known to kill cancerous tissue by heating the affected area. In recent years, it has also been considered to treat cancer from within the body cavity.

Conventionally, such technology has been disclosed in Japanese Unexamined Patent Application Publication No. 1989-1995 filed by the present applicant.
As shown in Publication No. 130640, there is an endoscope that has an infrared irradiator installed at the tip of the endoscope, and the infrared rays from the infrared irradiator are directed toward the affected area to heat the tissue. .

[Problems to be Solved by the Invention] However, since infrared rays of all wavelengths are irradiated simultaneously, there is a drawback that infrared rays cannot be generated efficiently. For this reason, it has not been possible to effectively perform heating therapy within the body cavity.

The present invention has been made in view of these problems and aims to effectively perform heating therapy within the body cavity.

[Means and operations for solving the problem] In this thermotherapy device, a far-infrared emitting ceramic 10 and a heating means 11 for heating the far-infrared emitting ceramic 10 are incorporated into an endoscope, and a body cavity is heated. Efficiently generates far infrared rays suitable for internal heating.

[Example] The present invention will be described below based on a first example shown in FIGS. 1 and 2. The drawing shows the tip structure of the insertion section of the endoscope, with observation window 1 on the tip surface on one side of the upper side bordering the center. Lighting window 3. The distal end portion 5 provided with the treatment instrument hole 4 is a flexible portion formed by covering a blade 6 with a flexible member 7.

The distal end component 1 is connected to the distal end portion of the flexible section 5 which is connected to an operating section (not shown). In addition, the flexible part 5
Image guide fiber inserted into 8. Ride guide fiber (not shown) connects 8 windows 2 and 3 to lens 9.
Similarly, a treatment instrument insertion channel (not shown) is connected to the treatment instrument hole 4.

The main parts of the invention are incorporated into a part of the distal end component 1 of such an endoscope. That is, window 2 of tip configuration 1,
3 and one side of the lower part where there is no treatment tool hole 4 is cut out from the tip to the root side, and a far-infrared emitting ceramic 1 is placed in this cutout.
0 together with a plate-shaped heater 11 (corresponding to heating means).

Specifically, the far-infrared emitting ceramic 10 includes, for example, AI! 2. A solid material with high far-infrared emissivity is used, which is made by mixing powders (usually powders) of ZrO2 and TiO2 and sintering them into a semi-cylindrical shape. A recess 12a for accommodating a heater is formed on the side surface of the far-infrared emitting ceramic 10 (semi-cylindrical solid material). Then, the heater 11 is installed in the recess 12a, and the entire far-infrared emitting ceramic 10 is installed in the notch of the tip component 1. This results in
Far-infrared emitting ceramic 10 with embedded heater 11
The structure is capable of heating (the structure required to generate far infrared rays). Further, a heat insulating member 12 is interposed between the bonding surface of the far-infrared emitting ceramic 10 and the bonding surface of the tip component 1, and the heater 11
image guide fiber 8. This is to prevent damage to the light guide fiber, etc.

Therefore, when performing thermotherapy using such a thermotherapy device, first, the target site is observed and the far-infrared emitting ceramic 10 is appropriately placed at the location of the tumor (cancer).

Next, when the heater 11 is made to generate heat to heat the far-infrared emitting ceramic 10, far-infrared rays that are highly absorbable to the human body are radiated from the far-infrared emitting ceramic 10. This allows the tumor within the body cavity to be heated while minimizing damage to normal tissue due to overheating.

Therefore, heating treatment within the body cavity can be effectively performed using an endoscope. Moreover, since the heat insulating member 12 insulates the image guide fiber 8 and other parts from heat, the components of the endoscope will not be damaged by the thermal treatment.

Note that the present invention is not limited to the first embodiment, but also includes the second embodiment shown in FIGS. 3 and 4, the third embodiment shown in FIGS. 5 and 6, and the embodiment shown in FIG. Embodiment 4, a fifth embodiment shown in FIG. 8, a sixth embodiment shown in FIG. 9, and a seventh embodiment shown in FIGS. 10 and 11 may be used.

That is, in the second embodiment, far-infrared emitting ceramics 10 are arranged around the entire outer periphery of the tip component 1.

In the third embodiment, a far-infrared emitting ceramic 10 is provided in a part of the tip component 1 similarly to the first embodiment. and,
In addition to providing a reflector 20 that reflects far infrared rays between the side surface of the far-infrared emitting ceramic 10 and the side surface of the notch, a gap 22 is provided in the ceramics 10 of the reflector 20, and the image guide fiber 8. light guide fiber 13
This prevents far infrared rays from entering the side. However, 23 is an insulator provided at the front and rear ends of the far-infrared emitting ceramic 10 and at the end of the reflector 20.

Of course, the far infrared rays may be reflected only by the void 22. However, in this case, it is necessary to polish the inner surface of the notch of the tip component 1 (to a mirror surface).

In the fourth embodiment, the tip component 1 itself is made of far-infrared emitting ceramic 10, and a heater 11 is embedded in this far-infrared emitting ceramic 10.

In the fifth embodiment, an image guide fiber 8. A far-infrared emitting ceramic 10 in which a heater 11.11 is embedded is provided along the axial direction of the tip component 1 at the tip of the tip component 1 in which the light guide fiber 13 is arranged. Note that the far-infrared emitting ceramic 1o may be placed on the hand side.

In the sixth embodiment, an infrared emitting ceramic 10 is used for a portion of a flexible member 7 constituting a flexible portion 5 of an endoscope. That is, the flexible portion 7 following the tip component 1
A is composed of a tube made of resin or the like with a far-infrared emitting ceramic 10 different from the flexible member 7 interposed therebetween, and a planar heating element 24 is provided inside this tube.

Specifically, for the tube structure, a porous material such as polytetrafluoroethylene, which is resistant to high temperatures and does not deform even when heated by the planar heating element 24, is used, and the pores of this porous material are injected with far-infrared radiation. A structure in which ceramics 10 are mixed is used. A planar heating element 24 is attached to the inner surface of this flexible tube. However, 25 is a protective layer of the image guide fiber 8.

Note that the resin mixed with such far-infrared emitting ceramics 10 may not be used all over the circumference, but may be used only in part. If you do this, you can press the resin part mixed with 10 in the body cavity and add 75! This has the advantage that only the target tumor can be treated without heating other normal tissues.

The seventh embodiment is a modification of the sixth embodiment, in which the flexible portion 7a mixed with the far-infrared emitting ceramic 10 is made detachable together with the planar heating element 24. in particular,
The diameter of the tip component 1 is made small so that the flexible portion 7a including the planar heating element 24 can be inserted into and removed from the protective layer 25 and the tip component 1, and as shown in FIG. A structure is used in which a cylindrical insulator 27 having a threaded portion 26 on the inner surface is connected to the tip of the threaded portion 7a, and the flexible portion 7a including the sheet heating element 24 is inserted and the tip portion 1 of the threaded portion 26 is inserted. It can be attached or removed by screwing into the outer periphery of the holder. However, a protective layer 2 is provided on the lower surface of the sheet heating element 24.
Two electrical contacts are provided for electrical connection with the power supply side lead wires 28 and 28 provided at 5.

Note that the planar heating element 24 may be provided on the endoscope main body side instead of on the flexible portion 7a side.

[Effects of the Invention] As explained above, according to the present invention, far-infrared rays suitable for heating the inside of a body cavity can be efficiently generated.

As a result, heating treatment within the body cavity can be effectively performed.
