Abstract

The epicardium ablation system comprises an ablation catheter and an ablation electrode catheter, the ablation catheter comprises a balloon, an adjustable bending structure, an endoscope, a guide wire channel, an ablation electrode channel and a guide wire, the endoscope is connected with an electrode controller, one end of the ablation catheter is connected with a handle, and a knob and a push button are arranged in the middle of one end of the handle. The knob is connected with the adjustable bending structure through a pull wire, a positioning assembly is arranged on the handle and located between the knob and the push button, one end of the knob is sleeved outside the handle and sleeved with a positioning ring, and the positioning assembly is connected with the positioning ring in a matched mode. The ablation catheter handle structure has the advantages that the front end is kept in the current bending state, the locking state can be relieved in time through the reverse positioning assembly, and a doctor can operate with one hand under the condition that precision and stroke are controlled.

Description

technical field [0001] The invention relates to the technical field of medical mapping catheters, in particular to an epicardial ablation system. Background technique [0002] Atrial fibrillation is one of the most common clinical tachyarrhythmias. Epidemiological data show that the total prevalence of atrial fibrillation in my country is about 0.7%, and the incidence and prevalence gradually increase with age. Atrial fibrillation can lead to stroke and deterioration of cardiac function. It is an important cause of death and disability in patients, greatly reducing the quality of life of the population and increasing the social burden. Therefore, the treatment of atrial fibrillation is particularly important. Due to the complex physiological structure of the human body, different shapes of the distal end of the catheter and handles with superior manipulation performance are required. It is extremely challenging to make the catheter reach different lesions accurately and ada...
