Radio frequency closure catheter and manufacturing method thereof

Abstract

The invention discloses a radio frequency closure catheter. The radio frequency closure catheter mainly comprises a catheter body, a handle device, a connecting cable and a connector which are sequentially connected from the far end to the near end, and the catheter body is sequentially provided with a rubber head, a heating section and a main body pipe from the far end; an insulating outer sleeve with insulating and smoothing effects is arranged on the surface of the heating section, a coil used for heating and formed by winding alloy wires is arranged in the heating section, and the coil comprises a near-end coil and a far-end coil; and extension lines of the near-end coil and the far-end coil extend to the handle device through an inner cavity of the main body pipe and are connected to the connector through the connecting cable, and the connector is connected with external equipment to provide radio frequency current. According to the radio frequency closure catheter, radio frequency closure of two diseased regions including superficial varicose veins and traffic varicose veins of lower limbs can be achieved under the condition that instruments do not need to be replaced, related operation risks are avoided, and the operation time is shortened.

Description

technical field [0001] The invention relates to a medical instrument for interventional treatment, in particular to a radio frequency closed catheter for treating superficial veins of lower extremities and communicating varicose veins and a manufacturing method thereof. Background technique [0002] Varicose veins of the lower extremities are the most common endovascular diseases, and varicose veins are the most common. The prevalence rates of adult men and women in my country are as high as 10%-15% and 20%-25% respectively. The latest statistics from the World Health Organization show that there are more than 100 million people in China suffering from varicose veins of the lower extremities, which has become a major disease in major primary hospitals in China. one of the species. The clinical manifestations of varicose veins of the lower extremities are varicose blood vessels on the surface of the skin of the legs like earthworms. itching etc. The pathological mechanism o...

AI Technical Summary

Problems solved by technology

[0005] There are still some aspects that need to be improved in the current radiofrequency ablation treatment. For example, in the radiofrequency ablation treatment of the superficial veins and communicating veins of the lower extremities, since different instruments are required for superficial veins and communicating veins, there is a risk of instrument replacement, and prolonged surgery time
