Abstract

The invention provides a magnetic field system, a magnetic navigation system and a catheter movement control method. The magnetic field system comprises two side-by-side magnetic field generators; each magnetic field generator comprises an electromagnetic matrix and a control system; the electromagnetic matrix comprises multiple electromagnetic units arranged according to a pre-set rule; the control system comprises multiple control units arranged to be in one-to-one correspondence with the multiple electromagnetic units; the control units control working states of the corresponding electromagnetic units; and thus, the electromagnetic matrix is controlled to generate a working magnetic field satisfying a pre-set condition. According to the magnetic field system in the invention, the magnitude and direction of current of the corresponding electromagnetic unit are adjusted through each control unit; therefore, the magnitude and direction of a magnetic field generated by each electromagnetic unit can be adjusted, so that two magnetic field generators can be controlled to generate the working magnetic field satisfying the pre-set condition; the problem that equipment is big and heavy due to adoption of a permanent magnet in a related technology can be overcome; and furthermore, the working magnetic field is relatively rapid and flexible to adjust and control.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a magnetic field system, a magnetic navigation system and a control method for catheter movement. Background technique [0002] In related technologies, permanent magnet navigation technology is used in magnetic navigation therapy surgery. The principle is: a plurality of permanent magnets of different lengths, sizes and shapes that have been designed and actually measured are used, arranged and bonded into a hemispherical working magnet, and the cascade arrangement of the magnets face to the workspace. Fix the hemispherical working magnet on the base of 10 high-speed motors according to the 8-way working mode. Two oppositely placed hemispherical working magnets jointly construct a working magnetic field and a working area. Through the movement of the CNC motor, a single working magnet can complete front and rear, up and down, left and right up rotation, left and righ...
