Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a microwave treatment device with an infrared heater that heats living tissue using microwaves.
In particular, the present invention relates to a microwave treatment device with an infrared heater that improves the heating effect.

[Prior Art] Conventionally, treatment devices using microwaves or infrared rays are generally known. Among these, those using microwaves have advantages such as good straightness, penetrating power into living organisms, and ease of focusing the beam. For this reason, those using microwaves are suitable for intensively heating the treatment area. On the other hand, those using infrared rays have the advantage of being able to efficiently heat the living body with less refraction on the living body surface due to the long wavelength, and have the ability to penetrate into the living body over a wide range. .
Furthermore, a wavelength of 8 to 10 μm is usually used because it has the highest penetrating power.

[Problems that the invention aims to solve] As mentioned above, treatment using microwaves and treatment using far infrared rays have different therapeutic effects, and in order to obtain the therapeutic effects of both, it is necessary to use each treatment device. had to be treated separately using In this case, the treatment time becomes longer and
Since two treatment devices had to be prepared, a problem arose in that a large amount of space and cost were required. Additionally, in order to shorten the treatment time, it is possible to drive each treatment device at the same time, but it is difficult to make each treatment device act at a good rate on the same treatment area, and it is difficult to operate each treatment device at the same time. Another disadvantage is that the irradiation position of each treatment device must be individually reset.

This idea was created in view of the above-mentioned circumstances, and allows the therapeutic effects of both microwave and infrared rays to work simultaneously, as well as being able to adapt immediately to changes in the treatment area. The purpose is to provide a microwave treatment device with an external heater.

[Means for solving the problem] This invention includes an infrared generator that emits infrared rays in the same direction as the microwave radiation direction within the guide of a microwave treatment device that heats living tissue using microwaves. It is characterized by being attached.

[Function] According to the above configuration, an infrared ray generator that uses infrared rays that heats a living body over a wide range is added to a microwave generator that uses microwaves that heat the living body partially and deep. Since the device is provided, it is possible to simultaneously heat the living body over a wide area and partially and deeply.

[Example] This invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the structure of an embodiment of this invention.

In the figure, 1 is a vertically long box-shaped device body, and an operation panel 1 is provided on the top surface of this device body 1.
a is provided so as to be inclined forward. This operation panel 1a has an output meter 2 on the left side of the center, a lamp 3 indicating on/off of the power supply voltage on the right side of the center, and a microwave output period (for example, 15
A timer 4 for setting the output period (minutes), a potentiometer 5 for adjusting the microwave output at the bottom center, and a timer 6 for setting the far-infrared output period (for example, 60 minutes) at the bottom right side are provided.

Next, an L-shaped member 7 is fixed to the upper right side of the device main body 1 as shown in the figure. An arm fixing member 8 is provided on the upper surface of this member 7. An arm 9 is attached to the arm fixing member 8 so as to be movable in the vertical direction (0 to 130 degrees), and the arm 9 can be fixed at any vertical position by screwing in the knob 8a clockwise. I can do it. The arm 9 is extendable and retractable, and can be fixed at any length by tightening a knob 10a of a fixing member 10 that is attached to the arm 9 by penetrating it. Further, a conductor 11 is attached to the tip of the arm 9 so as to be rotatable with respect to the arm.

Here, the structure of the conductor 11 will be explained with reference to FIG. In this figure, 12 is a coaxial cable (for example, RG-14u). A joint balloon 13 is attached to the tip of the coaxial cable 12. Balloon for joint 1
A spiral antenna 14 is connected to the core wire 12a of the coaxial cable 12 protruding from the coaxial cable 3. The antenna 14 is fixed by a support member 16 provided within the joint 15 and a heat insulating member 17 (eg, glass fiber) provided at the end of the joint 15.

Next, 18 is an outer cover composed of a small diameter part 18a with a small diameter and a large diameter part 18b with a large diameter.
A heat insulating material 19 having the same diameter is attached with its axes aligned. A flange 19a is formed at the left end of this heat insulating material 19. The flange 19a has
A thick ring-shaped far-infrared heater 20 is attached. In addition, a far infrared heater 20
The power cable 21 is connected to the main body of the device (see Figure 1).
Connected to 1. Further, a ceramic heat insulating material 22 formed in a disk shape is attached to the left end of the heat insulating material 19. This ceramic insulation material 22
This is to prevent the heat radiated from the far-infrared heater 20 from being transmitted to the antenna 14. Further, a curved reflection plate 23 is provided extending from the left end of the large diameter portion 18b to the peripheral edge of the flange 19a of the heat insulating material 19. A wire mesh 24 that covers the inside is attached to the left end of the large diameter portion 18b.

Here, FIG. 3 is a view of the conductor taken along the line AA. As shown in this figure, a heater 20 is provided concentrically outside the antenna 14.

According to the above configuration, since the antenna 14 and the far-infrared heater 20 are arranged concentrically, the irradiation range of microwaves and far-infrared rays can be made concentric. Thereby, it is possible to widely heat the area around the treatment area.

Next, a conductor which is a second embodiment of the above-mentioned conductor 11 is shown in FIG. A curved antenna 26 is provided inside the conductor 25 shown in this figure, and microwaves are radiated from this antenna 26 in the direction of arrow B. Further, as shown in the figure, the upper and lower portions of the conductor 25 are each inclined in the microwave radiation direction. Far-infrared heaters 27 and 28 are provided above and below, respectively.

According to the above configuration, the far infrared heater 27,
28 is provided at an angle in the microwave radiation direction, far infrared rays are fused with the microwave at a predetermined position. Thereby, far infrared rays and microwaves can be irradiated to the treatment area in the same range. Note that reference numerals 29 and 30 are reflection plates.

As described above, according to this invention, microwaves and far infrared rays can be emitted at the same time, so that the therapeutic effects of both can be exerted. That is, it is possible to heat the treatment area locally and deeply by irradiating with microwaves, and over a wide range by irradiating with far infrared rays.

In this embodiment, the movement of the arm 9 is limited to the vertical direction, but it may also be allowed to move horizontally.

[Effects of the invention] As explained above, according to this invention, an infrared generator that emits infrared rays in the same direction as the microwave radiation direction is installed in the conductor of a microwave treatment device that heats living tissue using microwaves. Since I installed the device,
The therapeutic effects of both microwave and infrared rays can be applied simultaneously, and changes in the treatment area can be immediately adapted.
