Guiding multiple alternating field focusing type magneto calorific therapeutic machine

Abstract

The invention relates to a magnetic induced heat treatment device in magnetic field focusing type used for guiding multi-alternations, which can further exert a heating effect with certain dispersed nano particles, improves the medical efficiency, reduces the difficulty requirement of the external power supply, and causes the related device to become small-sized and energy-saving. The power supply (3) of the treatment device comprises a plurality of low power supplys which are serially connected or parallel connected with each other; a magnetic filed launcher in focusing type (8) is composed by a plurality of output seekers (81)which are serially connected or parallel connected; the low power supplys are distributed in a power frequency regulator (6) according to the number and parameter of the output seeker (81) to reach the optimal matching effect of a plurality of low power supplys and a plurality of output seekers (81); a plurality of output seekers (81) cause the magnetic filed with different energy to realize the focusing in the object region, and cause the energy of the magnetic field in the object region to satisfy the thermotherapy requirement of various temperature values in clinic.

Description

technical field [0001] The invention relates to a device for tumor treatment, which belongs to the technical field of hyperthermia technology in biomedical engineering. Background technique [0002] Hyperthermia has been shown to be a very effective method of treating tumors. So far, many hyperthermia techniques have been developed, including radiofrequency, microwave, ultrasound, hot water perfusion, magnetothermal therapy, etc. Among these methods, magnetic hyperthermia uses an alternating magnetic field generator to generate an alternating magnetic field at the lesion site, and at the same time, heat seeds or ferromagnetic particles are placed in the lesion to form a temperature increase in the lesion area, thereby killing Methods of killing tumor cells. Because this technology pre-embeds thermal seeds in the lesion through surgery, or distributes particles in the lesion through a certain interventional method, there is no high positioning requirement for the loading of...

AI Technical Summary

Problems solved by technology

Of course, there are also some shortcomings in magnetic hyperthermia, that is, the thermal seeds or ferromagnetic particles used in the body must have very good biocompatibility and high thermal efficiency. How to place these materials reasonably and effectively on the lesion It needs special research; in addition, because the magnetic field applied outside the body is very strong, it is still very difficult to realize
