Catheter ablation system

Abstract

The catheter ablation system comprises an ablation catheter, a power supply and a power supply controller, and one or more ablation electrodes and one or more pressure sensors are arranged at the head end of the ablation catheter; the pressure sensor is used for detecting a real-time pressure value; the power supply controller is used for receiving the real-time pressure value and judging whether a discharge condition is met or not according to the real-time pressure value, and if yes, the power supply is controlled to supply power to the ablation electrode. According to the catheter ablation system, a power supply controller directly obtains the real-time pressure value of a pressure sensor and controls a power supply to supply power to an ablation electrode when the discharge condition is met, the pressure value obtained in the process is the real-time pressure value, and the judgment action does not need human participation; the power supply opportunity can be automatically, quickly and accurately judged, the judgment delay is small, the accuracy is high, the reliability of the catheter ablation system is improved, and the operation threshold of the catheter ablation system is lowered.

Description

technical field [0001] The invention relates to the field of ablation catheters, in particular to a catheter ablation system. Background technique [0002] At present, in the existing catheter ablation surgery, the operator uses the ablation catheter with a pressure sensor installed at the head end, and artificially judges the stability of the catheter by observing the position of the catheter displayed on the man-machine interface of the ablation device or the 3D navigation device connected to it. , and after confirming that the catheter is firmly attached to the myocardium, the device is manually controlled to output ablation energy. [0003] However, the pressure value displayed on the current ablation equipment or human-machine interface is usually the average pressure value after smoothing, not the real-time value. The process of data processing, display, and artificial thinking takes a certain amount of time. In the resulting complex and changing surgical environment,...

Problems solved by technology

[0003] However, the pressure value displayed on the current ablation equipment or human-machine interface is usually the average pressure value after smoothing, not the real-time value. The process of data processing, display, and artificial thinking takes a certain amount of time. In the complex and changing surgical environment, this series of delays will greatly affect the timing of the ablation catheter. Therefore, whether the timing of the ablation is accurate is extremely dependent on the experience level of the operator, and the requirements for the operator are extremely high.
