Magnetocardiogram interventional probe and magnetocardiogram measuring system

Abstract

The invention discloses a magnetocardiogram interventional probe and a magnetocardiogram measuring system.The magnetocardiogram interventional probe comprises a probe body, a catheter, a microwave waveguide and a radiation structure, the catheter is connected with the probe body, the microwave waveguide is embedded in the catheter and extends in the length direction of the catheter, one end of the microwave waveguide is connected with a microwave system, and the other end of the microwave waveguide is connected with a power source; and the radiation structure is arranged in the probe body and is used for emitting microwaves transmitted by the microwave waveguide to the periphery. According to the magnetocardiogram interventional probe, the catheter is connected with the probe body, the microwave waveguide is embedded in the catheter and extends in the length direction of the catheter, one end of the microwave catheter is connected with the microwave system, the radiation structure is arranged in the probe body, and microwaves transmitted by the microwave waveguide are diffused all around through the radiation structure; the magnetocardiogram interventional probe can emit microwaves after entering the blood vessel of the human body, and meanwhile, a coil of the magnetocardiogram interventional probe is omitted, so that the size of the interventional probe can be reduced, and the measuring range of a magnetocardiogram measuring system can be widened.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a magneticocardiographic interventional probe and a magneticocardiographic measurement system. Background technique [0002] In related technologies, in the magnetic field measurement system, electromagnetic waves are emitted outside the human body, and coils are set in the interventional probe to receive electromagnetic wave signals. When the coil is too small, the detection accuracy will be affected, so the coil in the interventional probe cannot be too small, so that The volume of the interventional probe cannot be reduced, so that the interventional probe cannot reach a deeper position in the blood vessel, and the measurement range of the magnetic field measurement system is limited. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention prop...
