Description

Magnetic ring array therapeutic device The application discloses a divisional application of China patent application with the name of 'magnetic ring array treatment device' which is filed by China patent office, application number 202110843877.7 and is issued by the year 2021 and month 07 and 26. Technical Field The invention relates to the field of medical equipment, in particular to a magnetic ring array treatment device. Background It is well known that tumors, particularly malignant tumors or cancers, have uncontrolled proliferation of cell division, rapid growth, low cell differentiation, and wettability and diffusivity (migration) as compared to normal tissues. As mentioned above, the rapid growth of tumors in general (and malignant tumors in particular) is a result of relatively frequent cell division or proliferation compared to normal tissue cells. The frequent cell division of cancer cells relative to normal cells is the basis for the effectiveness of existing cancer therapies, such as radiation therapy and the use of a wide variety of chemotherapeutic agents. Such treatments are based on the fact that cells undergoing division are more sensitive to radiation and chemotherapeutic agents than non-dividing cells. Because tumor cells divide more frequently than normal cells, it is possible to selectively damage or destroy tumor cells by radiation therapy and/or chemotherapy to some extent. The actual sensitivity of a cell to radiation, therapeutic agents, etc. also depends on the specific characteristics of different types of normal or malignant cell types. Thus, unfortunately, tumor cells are not significantly more sensitive than many types of normal tissue. This makes it less easy to distinguish between tumor cells and normal cells, and thus existing typical treatment regimens for cancer can also cause significant damage to normal cells, thereby limiting the therapeutic efficacy of such treatments. Furthermore, the inevitable damage to other tissues makes the treatment very damaging to the patient, and the patient often cannot recover from seemingly successful treatments. Moreover, some types of tumors are not sensitive at all to existing treatments. Other methods exist for destroying cells that do not rely on radiation therapy or chemotherapy alone. For example, methods using ultrasound or electrical disruption of tumor cells may be substituted for conventional treatments. Electric fields and currents have been used for medical purposes for many years. It is most common to maintain a potential difference between the conductive electrodes by means of a pair of conductive electrodes, and to generate an electric current in the human or animal body by applying an electric field in the human or animal body. These currents are either used to exert their special effect, i.e. to stimulate excitable tissue, or to generate heat by forming currents in the body, since the body can be equivalently resistive. Examples of the first type of application include cardiac defibrillators, peripheral nerve and muscle stimulators, brain stimulators, and the like. Examples of the use of electrical current to generate heat include tumor ablation, ablation of malfunctioning heart or brain tissue, cauterization, relief of muscle rheumatalgia or other pain, and the like. Other applications of electric fields for medical purposes include the use of high frequency oscillating fields emitted from sources emitting e.g. radio frequency electric waves or microwave sources directed to a site of interest in the body. In these examples, there is no conduction of electrical energy between the source and the body, but rather energy is transferred to the body by radiation or induction. More particularly, the electrical energy generated by the source reaches the vicinity of the body via conductors and is transferred from that location to the human body by air or some other electrically insulating material. In conventional electrical methods, electrical current is delivered to a target tissue region through electrodes placed in contact with the patient's body. The applied current will destroy substantially all cells in the vicinity of the target tissue. Thus, this type of electrical method does not distinguish between different types of cells within the target tissue and results in destruction of both tumor cells and normal cells.
