Superconductive magnet system for intercurrent treatment three-dimensional position

Abstract

A superconducting magnet system suitable for neurosurgery interventional operations. It mainly includes high-temperature superconducting magnets, G-M refrigerators, low-temperature Dewars, quench protection devices, and program-controlled power supplies. The high-temperature superconducting magnet is composed of three pairs of superconducting solenoid coils. Each pair of superconducting solenoid coils is composed of two layers of superconducting coils inside and outside. The two layers of coils are stacked, and each pair of coils is placed along an axis of the Cartesian coordinate system. , the axes of the three pairs of coils are perpendicular to each other, and the whole magnet forms an asymmetric open space. The magnet system operates in a cryogenic system protected by solid nitrogen. The invention is not only more convenient to use and operate, but also more stable in system operation, greatly reducing the possibility of magnet quenching; at the same time, the invention adopts a new coil structure to simplify the system and make the available space larger increase; the use of refrigerator conduction cooling and external solid nitrogen protection makes the system more reliable at low temperatures.

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...
