Problems solved by technology

However, when a hemangioma is formed, the blood vessel wall on the other side perpendicular to the axial direction is also thinned, and the other side of the tumor capsule may be further thinned and a new tumor capsule will be formed after closing one side of the tumor capsule, so the treatment effect is not ideal; for For fusiform hemangioma, ordinary hemangioma clips are powerless

Embodiment Construction

[0018] Example: as attached figure 1 and 2 As shown, the hemangioma clip with membrane is composed of a metal clip and a synthetic material wrapping film 3, wherein the metal clip includes a first clip bar 5 and a second clip bar 6 whose tails are connected by an elastic device 7 and overlap each other. The ends of the half collar 8 on the first clamp bar 5 and the half collar 9 on the second clamp bar 6 are respectively provided with the first clamp arm 1 and the second clamp arm 2; On the first clamping arm 1 and the second clamping arm 2, a membrane sleeve is formed. The length of the wrapping film 3 is equal to the circumference of the corresponding collar 4 formed by the half collar 8 and the half collar 9, and its width is equal to the arm length of the jig arm or both ends are 1 -2mm. The wrapping film 3 is a film or a braided net made of synthetic materials such as polytetrafluoroethylene, polyester, polyurethane, polypropylene, polysiloxane, polyamide or polyester ...

Abstract

The invention discloses a vessel tumour clamp with biological film, which consists of metal clamp and biological film (3), wherein the metal clamp is made of medical stainless steel or Ti alloy, which contains first clamp rod (5) and second clamp rod (6) connected by elastic device (7) on the tail part; the first clamp arm (1) and second clamp arm (2) are encased on the end of semi-casing rings (8) and (9) of first and second clamp rods (5) and (6) separately; two ends of biological film (3) are fixed on the first and second clamp arms (1) and (2) to form film sleeve.

Description

technical field [0001] The invention relates to a hemangioma clip, which is a device for treating hemangioma and belongs to a medical device implanted into a human body. Background technique [0002] Hemangioma, especially aneurysm, is one of the common vascular diseases. There are many ways to treat hemangioma. For some forms of hemangioma, use hemangioma clips to clamp the aneurysm capsule from the root (parallel to the vessel wall). Closing the tumor capsule is a simple treatment method, especially suitable for those parts that are difficult to expose. This method has been clinically used for a long time, and the short-term effect is good. However, when a hemangioma is formed, the blood vessel wall on the other side perpendicular to the axial direction is also thinned, and the other side of the tumor capsule may be further thinned and a new tumor capsule will be formed after closing one side of the tumor capsule, so the treatment effect is not ideal; for For fusiform hem...
