Magnetic steering targeted therapy device

Abstract

The invention discloses a magnetic steering targeted therapy device which comprises a base, a vertical main lifting rod, a transverse telescopic rod, a vertical auxiliary lifting rod and magnetic generation plates. The base is connected with the lower end of the vertical main lifting rod, the upper end of the vertical main lifting rod is connected with the left end of the transverse telescopic rod, the right end of the transverse telescopic rod is connected with the vertical auxiliary lifting rod, and the two ends of the vertical auxiliary lifting rod are each connected with one magnetic generation plate. The device is characterized in that a central controller is fixedly connected to the joint of the transverse telescopic rod and the vertical main lifting rod, and a transformer, a microprocessor chip and a memory are integrated and connected in the central controller; the right end of the transverse telescopic rod is connected with the middle of the vertical auxiliary lifting rod through a full-angle rotating shaft; the upper section and the lower section of the vertical auxiliary lifting rod can ascend and descend; and the distance between the two magnetic generation plates and the body surface and the magnetic force can be automatically controlled and adjusted, and through the series of automatic control and adjustment, medicine can be completely and accurately attracted to the focus position to act.

Description

technical field [0001] The invention belongs to the technical field of malignant tumor treatment, and in particular relates to a magnetic guidance targeting therapy device. Background technique [0002] In recent years, magnetic targeting therapy technology for the purpose of directional delivery and fixed-point release of drugs has become one of the mainstream and effective treatment methods for malignant tumors; The magnetic field is applied to the tumor site, and then the magnetically responsive drug is magnetically attracted by the action of an external magnetic field, so that it gathers at the target site of the tumor, increases the drug concentration and effect at the tumor target site, and reduces the effect of the drug on other healthy parts of the body. s damage; [0003] At present, the external magnetic field for magnetically guided targeted therapy is simply realized by ordinary magnetic sheets, which has the following disadvantages: 1) The magnetic blocks that ...

Problems solved by technology

[0003] At present, the external magnetic field for magnetically guided targeted therapy is simply realized by ordinary magnetic sheets, which has the following disadvantages: 1) The magnetic blocks that generate magnetic force do not have special fixing devices, and may need to be held by others; The guided and targeted therapy device can only target a single part, and its universality is not strong; 3) It is impossible to adjust the angle of the magnetic block according to the patient's body position to make the magnetic force more concentrated; 4) It is impossible to adjust the magnetic force. Different tumor locations have different distances from the body surface. If only a single magnetic force is used for magnetic guidance, the drug may not be able to fully concentrate on the affected area because the magnetic force is too small, or the drug may not be effective because the magnetic force is too large. 5) At present, when magnetic guidance is used, only a magnetic block is placed on the side of the patient's tumor corresponding to the body surface, which will lead to magnetic deviation, resulting in inaccurate concentration of the drug, and the magnetic block on one side cannot Adjust the position of the drug through magnetic balance adjustment
