Electric blood vessel coagulation appliance

Abstract

The electric vascular coagulator for treatment of varicosity of lower limbs includes elastic electrically coagulating guide wire, insulating canal holding the electrically coagulating guide wire, and opened electrically coagulating clack-spring head set in the end of the guide wire and capable of extending from and withdrawing into the end of the canal axially. It has simple structure and convenient operation, and by means of electrically burning inner membrane of blood vessel, may be reached the effects of making blood vessel deform, necrose and adhere similar to excision of the blood vessel. Compared with traditional operation, the present invention has the advantages of less cut and damage, less influence on leg appearance and fast post-operation restoring.

Description

technical field [0001] The invention relates to an appliance for surgical operations, in particular to a blood vessel electrocoagulator for treating varicose veins of the lower extremities. Background technique [0002] As we all know, varicose veins of the lower extremities is a common peripheral vascular disease in clinical practice. Except for a small part of primary saphenous varicose veins, most of them are secondary to deep venous insufficiency. As the exact treatment of primary varicose veins and the symptomatic treatment of secondary varicose veins of the lower extremities, the traditional surgical methods—high ligation and segmental stripping—are based on resection of varicose veins and have been used clinically for a long time. Although this method can cut off the backflow of blood from top to bottom and from deep to shallow and remove the expanded varicose veins, it has many incisions, large trauma, long postoperative recovery period, and affects the appearance of...

Problems solved by technology

Although this method can cut off the backflow of blood from top to bottom and from deep to shallow and remove the expanded varicose veins, it has many incisions, large trauma, long postoperative recovery period, and affects the appearance of the legs. When the vein is stripped, the small branch of the vein will rupture and bleed, causing permanent or temporary damage to the accompanying saphenous nerve and lymphatic vessels, resulting in complications such as subcutaneous hemorrhage, sensory disturbance in the calf and medial foot, and small lymph node swelling in the calf. willing to accept
