Problems solved by technology

[0006] After the traditional vein stripping or surgical treatment, you need to rest for 3 weeks, and the scars left at the same time are also relatively large; another non-surgical vascular sclerotherapy is to block the varicose veins by injecting radioactive substances, which has a certain effect on the normal body. damage and the possibility of recurrence of varicose veins

Abstract

A radiofrequency ablation bipolar catheter is characterized by comprising a first outer conductor (1), a PTC thermistor layer (2), a second outer conductor (3), an insulated conduit (4), a first inner cable (5) and a second inner cable (6). The insulated conduit (4) is in the shape of a bar. The tail end of the insulated conduit (4) is in the shape of an arc. The barrel-shaped first outer conductor (1) and the barrel-shaped second outer conductor (3) are respectively arranged on the outer surface of the insulated conduit (4). The PTC thermistor layer (2) is arranged on the inner wall of the first outer conductor (1). The radiofrequency ablation bipolar catheter and a treatment device with the radiofrequency ablation bipolar catheter can accurately control ablation temperature through a PTC.

Description

technical field [0001] The invention relates to the technical field of medical radiofrequency ablation, in particular to a radiofrequency ablation bipolar catheter and a treatment device comprising the radiofrequency ablation bipolar catheter. Background technique [0002] Minimally invasive ablation is the development trend of the medical industry. Among them, thermal ablation has become the mainstream of ablation treatment because of its definite effect. Thermal ablation mainly includes three types: microwave, laser, and radiofrequency. Each thermal ablation method has its own advantages and disadvantages. These three types of minimally invasive thermal ablation treatment methods are all realized by various ablation electrodes. The ablation electrodes can be roughly divided into hard electrodes and soft electrodes in terms of structure. Vascular interventional therapy mainly relies on soft electrodes (superficial vascular intervention Hard electrodes can be used), such as...
