Description
Technical field
The present invention relates to technical field of medical equipment, and in particular to a kind of magnetic field induction thermotherapeutic apparatus.
Background technique
Since ancient times, either human body or surrounding environment, we tackle viral source, and the most simple also best mode of effect is
It is using " baked wheaten cake ".The discovery of modern science circle, is compared, tumour and cancer cell can be than normal histocytes for temperature in generally
It is sensitive, it is estimated that, about in 42 DEG C, such cell just loses vigor, and reaches 46 DEG C, then can be inclined to death.Technique for hyperthermia is object
Reason concept is a kind of gimmick of human body diseases treatment.However, in order to generate high temperature so that up to thermotherapy effect, physical means are with regard to different
And foot, there are also the technologies such as laser, ultrasonic wave.
In recent years, regardless of internal medicine or surgery are to the treatment behavior of human body, focus on very much over the course for the treatment of how to drop
It is low to pain caused by patient and injury, also just have the concept and demand of Minimally Invasive Surgery.In tumor thermotherapy technology in response to minimally invasive
Under the conditions of purpose, electromagnetic thermal therapy technology starts to develop before more than 30 years.The type of electromagnetic thermal therapy technology, according to use frequency
Rate and the mode of operation, can be divided into three kinds:
1, radio frequency is sintered: its electromagnetism working principle is Ohmic heating, first at the thigh of patient, puts an earth plate,
It is inserted in the affected part of patient using a so-called RFA needle, and adds the electric current of a frequency 460kHz or more, using circuit loop,
A high-density current area is formed at needle point to be sintered tumour to form high temperature.
Disadvantage: frequency is more unstable with current control of the electric current at needle point, and easy temperature is crossed high conduction and damaged just
Often tissue, and range is smaller, need to repeatedly be inserted into, be easy sense of discomfort.
2, microwave sintering: the treatment system of microwave sintering is utilizing a microwave antenna needle, then import and mentioned by signal generator
For and come high-power (30W~50W) microwave after, i.e., radiated at the tumour affected part of inside of human body, to make high temperature sintering.It is micro-
Wave needle main body is a coaxial line structure, is designed to a slot antenna or unipole antenna at tip to make microwave radiation.At present
In the world, the system in hospital's use or in research, the frequency probably used is not that 2.45GHz is exactly UHF 910MHz (preceding
Afterwards).Two frequency ranges all belong to be used for industry, science and medicine.The characteristic of two kinds of frequency ranges is, the former is tiny to be suitble to minimally invasive, but is sintered
Region is small；The latter is slightly long and to be sintered region big.From the point of view of the angle of tumour doctor, the ideal region that is sintered is 5cm diameter or more
Round shape volume.
Disadvantage: it is better than radio frequency effect, but can not popularize.The use of microwave needle has all passed through although the system person listed
The approval of U.S. FDA, still, it is the microwave antenna radiation source of one 30~50W after all, in operation ward, microwave when operation
The consideration of safety can bring great pressure to doctor thing personnel (this Electromgnetic seat factor is just paid close attention to by FDA recently).
Its sintering volume still dislikes too small at present, and microwave sintering system sufferer burden is high.Although framework is simple, also have the product of listing,
But most of range that can be born far more than patient, cannot still be considered as an ideal electromagnetic thermal therapy technology.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of structure is simple, design rationally, make
With convenient magnetic field induction thermotherapeutic apparatus, wound is smaller than radio frequency sintering system microwave, while cheaper, and practicability is more
By force.

No.1 Hull Mu Huozi coil is arranged on the longitudinal edge on road；Above-mentioned No.1 Hull Mu Huozi coil and No. two Hull Mu Huozi lines
Circle is connect with power supply unit；The described strip magnetic circuit setting is symmetrically arranged at two " between the upper horizontal edge of U " shape magnetic circuit；
The intrusion needle is plugged in human body, is made of stainless steel needle body and iron element needle body；Iron element needle body is plugged in stainless pin
In the end head of body.
Further, the contact position of the iron element needle body and stainless steel needle body is equipped with ceramic glue.
Further, the iron element needle body is Ni Zn ferrimagnet needle body.
Further, described " U " shape magnetic circuit and strip magnetic circuit be amorphous metal magnetic circuit.
Further, the length of the strip magnetic circuit is 16-22cm.
The working principle of the invention: the different strip magnetic circuit of selection length is realized to by two " U " shape magnetic circuit and strip
Magnetic circuit is formed by the adjusting of Magnetic induction coil size, and the Magnetic induction coil of formation generates vortex to the intrusion needle in merging human body with life
Heat achievees the purpose that thermotherapy, which is suitable for ward system.
After adopting the above structure, the invention has the following beneficial effects: a kind of magnetic field induction thermotherapeutic apparatus of the present invention, wound
Wound is smaller than radio frequency sintering system microwave, while cheaper, and practicability is stronger, and the present invention has structure simple, and setting is closed
