Embodiment 1

[0022] Such as figure 1 As shown, the valve repair clip body of this embodiment is applied in the technical field of medical device implants for repairing damaged valves.

[0023] It should be noted that the surface of the jig 3 is one or more surface structures such as a smooth surface, a microporous surface, a frosted surface, a serrated surface, and a grooved surface.

[0024] This embodiment provides a valve-covered valve repair clip body, including a first clip body 4 and a second clip body 5, the first clip body 4 and the second clip body 5 are clamped to form a clip 3, preferably, the first clip body The clip body 4 and the second clip body 5 form a clip 3 through insertion. There is a coating on the clamp 3, wherein the coating includes an inner coating 2 and an outer coating 1, the inner coating 2 is wrapped in the clamping part of the clamp 3, and the outer coating 1 is wrapped in the clamp 3 The outer surface.

[0025] The structure of the inner layer coating 2 i...

Embodiment 2

[0042] The difference between the valve-covered valve repair clip of this embodiment and the first embodiment is that:

[0043] The outer membrane 1 is wrapped around the outer surface of the inner membrane 2, and the inner membrane 2 is wrapped on the outer surface of the clamp 3, and applied to the surface of the valve with complex shape and structure.

Embodiment 3

[0045] The difference between a kind of membrane-covered valve repair clip of this embodiment and Embodiment 1 is that:

[0046] The outer covering film 1 is wrapped around the outside of the inner covering film 2, and the outer covering film 1 is wrapped on the clamping surface of the clamp 3, and applied to the surface of the valve with complex shape and structure.

[0047] The invention utilizes the good blood compatibility of the inner coating and the good blood compatibility of the outer coating and blood contact, which can effectively reduce thrombus formation, maintain the performance of normal blood flow and biological fluid environment, and avoid implantation after surgery. The endothelialization time is too long, which improves the success rate of the operation and the convenience of the operation, and can be realized on the surface of valves with various complex shapes and structures.

Abstract

The invention belongs to the technical field of medical instrument implants, and particularly relates to a covering film type clamp for repairing the valve. The covering film type clamp comprises a first clamp body and a second clamp body, the first clamp body and the second clamp body conduct clamping to form a clamping tool, the clamping tool is provided with a covering film, the covering film comprises an inner layer covering film body and an outer layer covering film body, the inner layer covering film body wraps the clamping part of the clamping tool, and the outer layer covering film body wraps the outer surface of the clamping tool. By using the good blood compatibility of the inner layer covering film body and blood compatibility of good contact between the outer layer covering film body and the blood, forming of thromboses can be effectively reduced, and the performance of a normal blood flow biofluid environment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical device implants, and in particular relates to a membrane-covered valve repair clip body. Background technique [0002] The heart is one of the vertebrate organs. is the driving force in the circulatory system. The human heart is basically the same size as a person's fist, with the apex deflected to the left. Located above the diaphragm, between the mediastinum, to the lower left of the middle of the thorax, and to the left between the two lungs. The heart is composed of myocardium. It consists of four chambers: left atrium, left ventricle, right atrium, and right ventricle. The inner wall of the left ventricle is the thickest. These four chambers are the only way for systemic circulation and pulmonary circulation. The left and right atria and the left and right ventricles are separated by a septum, so they are not connected to each other. There are valves between the atrium and the ventricle, t...
