Varicose vein peeling device

Abstract

A varicose vein peeling device is provided. A spiral guiding head end (1) is connected with a tail end (4) via a plastic guide wire (2); at least four separation blocks (3) are arranged on the plastic guide wire (2); each spherical crown clamping peeling head (5) is formed by a round crown head (5-1) and a round truncated cone seat (5-2) axially clamped with each other; a center hole (5-4) is formed in an axial middle parts of the round crown head (5-1) and the round truncated cone seat (5-2); and an opening side slot (5-3) is respectively formed between outer walls of the round crown head (5-1) and the round truncated cone seat (5-2) and the center hole (5-4). The peeling head rotary clamping assembling structure is rationally structured and smartly designed; peeling heads of various external diameters can be conveniently selectively assembled and exchanged; great saphenous veins and varieose branch veins with lesions can be accurately peeled in a soft and smooth way on the whole; peeling trajection can be easily implemented; friction force of cutting surface tissues can be reduced; vasculopaty parts can be easily passes through; the peeling head cannot fall off, so operational risk can be reduced; and the varicose vein peeling device can be flexibly operated and reduce patient pains and blooding time.

Description

technical field [0001] The invention relates to a surgical cutting instrument belonging to IPC classification A61B17 / 32, which is specially used for stripping diseased blood vessels of patients with varicose veins, especially a varicose vein stripping device. Background technique [0002] Varicose veins is a common peripheral vascular disease, common in the great saphenous vein or small saphenous vein varicose veins of the lower extremities, manifested as earthworm-like stasis in the superficial veins of the lower extremities. Usually the valves in these veins have been damaged, and not only cannot return blood normally, but will lead to blood backflow or local dead circulation, which will cause tissue necrosis at the blood supply site. [0003] In the prior art, the method for treating varicose veins is to ligate the root of the great saphenous vein at a high position, and to perform stripping on the diseased great saphenous vein and varicose branch veins.

AI Technical Summary

Problems solved by technology

During the guide wire implementation process, the flexibility of the stainless steel wire guide wire is poor, and the front guide head with a simple cone shape will be restricted by obstacles such as venous valves or diseased blood vessels and large-angle blood vessel tortuous constraints, which will easily cause poor insertion and cannot be used for a long time. As the distance continues to advance, it is necessary to increase the incision multiple times and repeat the insertion and export process. The stripping head of the semicircular head cylinder is fixed on the guide wire by threading. Take out the guide wire as a whole, change the insertion direction, or unscrew the peeling head from the middle of the guide wire for replacement, which will prolong the operation time, increase the patient's trauma pain and the operator's work intensity
