Description

TECHNICAL FIELD

The present disclosure belongs to a technical field of radiofrequency ablation pincers, and particularly relates to an integrated electrode applied to bipolar radiofrequency ablation pincers.

BACKGROUND

In a related art, bipolar radiofrequency ablation pincers are a medical instrument applied to cardiothoracic minimally invasive surgeries, the radiofrequency ablation pincers are used for performing ablation isolation of circumferential pulmonary vein orifices at two sides, an ablation line is accurate, complete, and wall-penetrating, and it is an effective method for treating atrial fibrillation at present.

The atrial fibrillation is the most common arrhythmia clinically, according to statistics, there are about 8 million of atrial fibrillation patients in China, and population above 60 years old is a high risk group. The atrial fibrillation may generate many hazards to a human body. During the atrial fibrillation, a frequency of atrium beats is very fast, and irregular, a less serious patient may feel palpitation, shortness of breath, and debilitation, cardiac functions may be damaged more or less, if hypertension or a coronary heart disease is generated at the same time, risks of these heart diseases may be aggravated. The atrial fibrillation may also generate serious complication, such as ischemic stroke caused by falling off of atrial thrombus, the disability, and death may be caused.

The bipolar radiofrequency ablation pincers are used for performing a minimally invasive ablation surgery without extracorporeal circulation, and the surgery is performed in ^<a state that heartbeat is not stopped, principal steps are bilateral pulmonary vein isolation, left atrium circumferential pulmonary vein line ablation, epicardium partial denervation and left aurcle excision. The advantage is that surgery injury is small, operation is rapid and accurate, complication is less, and curative effect is good. Paroxysmal atrial fibrillation is used as a major treatment object internationally, and strictly selected persistent and perpetual atrial fibrillation is also included, a total curative ratio within 6 months may reach 91,3%. Surgery time is 2-4 hours generally, and average hospital stay is 3-5 days. After 6 months of the ablation, with regard to a patient of the paroxysmal atrial fibrillation, a sinus rhythm conversion rate is 80-90% (18-20). In addition, along with development of technologies, these surgeries are simpler and simpler, and easy to repeated operation. Compared with a catheter intervention technology, the minimally invasive surgery is one-time treatment, herein, a long-term curative ratio, according to existing abroad experience report, may reach about 90%. Experience of the atrial fibrillation treatment center of the Beijing Anzhen hospital is as follows: the sinus rhythm on discharge is 81.8% (18/22), and the sinus rhythm in 3 months after the surgery is 90% (9/10).

As shown in FIG. 1 and FIG. 2, a technical scheme of an electrode part of the bipolar radiofrequency ablation pincers in the related art is that an electrode groove 100 (as shown in FIG. 1) is reserved in an injection moulding process of an electrode base, after medical glue is applied in the electrode groove, an electrode wire 101 is pressed into the electrode groove (an electrode groove gluing layer 102 is formed in the electrode groove.), and integrally bonded and fixed with an electrode base 103 (as shown in FIG. 2). In a product working state of the electrode part of this bipolar radiofrequency ablation pincers in the related art, along with rising of a temperature of the electrode wire, bonding capacity of the gluing layer is reduced after hot-melting deformation, the risks of upwarp, ejection from the electrode groove or falling out exist in the electrode wire.

Thus it may be seen that after the bipolar radiofrequency ablation pincers in the related art are used for a long time, a working part easily generates problems of electrode upwarp and falling out, in a high temperature environment. In use, a temperature of a working terminal, namely the electrode part, of the bipolar radiofrequency ablation pincers is gradually ascended along with time, and the risks of upwarp and falling out exist in an electrode which is positioned in the high temperature environment for a long time.
