Embodiment Construction

[0013] Such as Figure 1 to Figure 4 shown. A device for venous valve reconstruction is characterized in that the device consists of two parts, A and B, wherein part A is a spindle-shaped patch, part B is a nerve fiber stripper, and the parts A and B should be used together. The normal state of the spindle-shaped patch is a flat product of polytetrafluoroethylene sheet. Its long side has a symmetrical V-shaped gap, and its short side is a groove-shaped side line. The side line should be sutured during the operation and set in the vein. On the wall of the blood vessel, a hollow tube is formed, and the two ends are bell-shaped. The inner diameter of the hollow tube should be determined according to specific conditions. The nerve fiber stripper used together with the spindle-shaped patch should assist the completion of venous valve reconstruction. Its function is to first strip the nerve bundle accompanying the venous blood vessel, and at the same time place it in the U-shaped ...

Abstract

The invention discloses reestablishing instrument of vein valve, which is composed of shaft-shaped sticking patch of plastic film or piece and nerve fiber stripper, wherein the normal condition of shaft-shaped sticking patch is plastic film and piece flat product, which possesses symmetrical V-notch; the short edge is symmetrical groove-shaped line; the vein vessel is planted on the external wall, which forms trumpet-shaped hollow pipe; the nerve fiber stripper is U-shaped plastic part with front end projecting with hole in the middle; the angle is inversed round; the polishing reaches gloss of mirror, which strips the nerve fiber on the vein vessel.

Description

technical field [0001] The invention relates to a hollow or tubular device implanted on the wall of a human vein, in particular to a device for venous valve reconstruction. Background technique [0002] In the 1980s, American scholar Kistner first proposed that primary deep venous valve insufficiency of the lower extremities would lead to backflow of blood, manifested as varicose veins of the lower extremities and calf ulceration. in medical practice. Although certain effects have been achieved, it can only be repaired on the basis of the original valve insufficiency, but it cannot be implemented for those with avalvular disease or severely damaged valves. According to medical statistics, the incidence rate of venous disease of lower extremities is 10%, which has become a relatively large disease that endangers people's health. [0003] The inventor, through more than ten years of medical clinical research and practice, has created a surgical accessory for venous valve rec...
