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

Disclosed is a radiofrequency ablation unipolar catheter. The radiofrequency ablation unipolar catheter is characterized by comprising an electrode ablation head (10), a PTC thermistor body (20) and an inner conductor (30), the electrode ablation head (10) is arranged at the end of the inner conductor (30), the PTC thermistor body is arranged between the electrode ablation head (10) and the inner conductor (30), and the inner conductor (30) is connected with a cable plug component (40). The radiofrequency ablation unipolar catheter and a treatment device comprising the same can accurately control ablation temperature through PTC.

Description

technical field [0001] The invention relates to the technical field of medical radiofrequency ablation, in particular to a radiofrequency ablation monopolar 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 the treatment of varicose veins, arrhythmia, vascular obstruction and other ...
