Abstract

A super-conducting magnetic system for the 3D location in insert therapy is composed of a high-temp super-conducting magnet unit consisting of three pairs of superconducting solenoid coils divided into internal and external layers, a G-M refrigerating unit, a low-temp cylinder, a superconductor-loss protector and a program controlled power supply. The whole magnet unit forms a symmetrical open space. The magnetic system is running in a low-temp system protected by solidified nitrogen.

Description

Technical field [0001] The invention relates to a superconducting magnet, in particular to a superconducting magnet system used for stereotaxic positioning of neurosurgical interventional treatment. Background technique [0002] In conventional interventional therapy, catheters are inserted into arteries or veins through the skin of the human body, and the movement of the catheter is achieved by applying force to the rear end of the catheter. Therefore, the catheter must be made of very hard materials to ensure The catheter will not be bent during the advancement process, but because the catheter is relatively hard, if the path is complicated, the catheter often cannot reach the destination. Therefore, in some important parts of the human body (such as the heart, brain), conventional interventional therapy is full of challenges and complexity, because its operation is difficult to control, and often requires skilled experts to spend several hours. Therefore, improving the o...
