Integrated system for cardiac ablation

Abstract

The invention relates to the technical field of cardiac ablation, in particular to an integrated system for cardiac ablation. The integrated system comprises a pulsed electric field ablation device, a three-dimensional marking system, a radio-frequency instrument and an ablation catheter, wherein the pulsed electric field ablation device comprises a magnetic signal receiving module, an electric signal receiving module, a pressure receiving module and an impedance detection module, and an electric signal, a magnetic signal, a pressure signal and an impedance signal of the catheter are separately transmitted to the three-dimensional marking system; and the three-dimensional marking system is used for carrying out analysis processing on the signals to obtain electrophysiological information on a patient, position information on the catheter and an attaching state of an operation position of the catheter. Under the control of the three-dimensional marking system, the system also realizes the switching of a pulse signal output by the pulsed electric field ablation device and a radio-frequency signal output by the radio-frequency instrument. The integrated system is more complete in design, pulsed electric field energy output, radio-frequency energy output and three-dimensional calibration can be achieved through one ablation catheter, and thus, the operation is simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of cardiac ablation, in particular to a comprehensive system for cardiac ablation. Background technique [0002] Existing thermal ablation methods mainly use radiofrequency and cryotechniques. However, during the use of this thermal ablation technique, it is often difficult to achieve full-thickness penetration due to the limitation of the thermal pool effect. At the same time, these thermal ablation techniques are not cell-selective, so non-target cells will be destroyed together. [0003] In view of the above defects of thermal ablation technology, pulsed electric field ablation technology, as a non-thermal ablation technology, has gradually attracted the attention of clinical application. Pulsed electric field ablation technology releases extremely high energy in a short time by generating a high-voltage pulsed electric field with a pulse width of milliseconds, microseconds or even nanoseconds, which ca...
