Problems solved by technology

[0012] The deficiency of this method is: 1) need very strong alternating magnetic field
2) Since the magnetic substance used is nanoparticles, it will have harmful effects after entering the body, and it is difficult to discharge
[0015] The disadvantage of this patent is that the attenuation of ultrasonic waves in the body is relatively large
On the other hand, its technical implementation is more difficult
In addition, the equipment used in the prior art is more complicated, and its manufacture is more difficult

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings, a demonstrative embodiment and its measured data.

[0038] see figure 1 , a solenoid 1 is provided on a U-shaped magnetic core 2 made of manganese zinc ferrite, and the two ends of the magnetic core 2 form two magnetic poles 4, and the terminal 5 of the solenoid 1 is connected to a high frequency power generator ( figure 1 not shown). The gap between the magnetic poles 4 is the place where the human body is placed. In the working state, the two magnetic poles 4 should be in the corresponding positions of the selected heating area 3, as shown in the figure.

[0039] An embodiment of the heating element of the present invention see appended figure 2 . Wherein a head 7 made of ferrosilicon alloy (silicon steel material can be directly used) is fixed at the front end of a bar 6 made of non-ferromagnetic material, forming a needle. The material of the rod 6 described h...

Abstract

The invention discloses a method and a device for fixed-point heating of certain specific positions in an animal body. The method of the present invention is to temporarily place a heating element of a ferromagnetic material in the part to be heated, and then establish an alternating magnetic field outside the body of the animal and at a position corresponding to the heated part, so that the temporarily inserted heating element acts on the alternating magnetic field. A vortex is formed underneath, heat is generated, and the heated part is heated. The device of the present invention is composed of a high-frequency power generator, a solenoid wound with a wire conductor or a tubular conductor, and a heating element that can be temporarily implanted in the animal body, wherein the gap between the two magnetic poles of the solenoid is large enough to accommodate the animal body Space. A magnetic core made of soft ferromagnetic material may be placed in the solenoid of the present invention.

Description

technical field [0001] The invention relates to a method and a device for fixed-point heating of some specific positions in an animal body, especially a human body. Background technique [0002] It is an effective treatment method to heat the specific lesion in the animal body, especially in the human body. For example, the use of local heating for space-occupying lesions such as tumors can cause tissue necrosis and effectively kill tumor cells. [0003] The methods for locally heating the body in the prior art include the following categories: [0004] 1. Microwave heating [0005] This method is to launch a microwave beam into the body. Under the action of high-frequency electromagnetic waves, polar molecules such as water molecules and protein molecules in the animal body are polarized and oscillate with the frequency of the external field. Molecules collide with each other, generating heat. For example, Chinese patent application 99117361.9, 02806478.X [0006] The ...
