A double-layer silicone nerve guide

Abstract

The invention discloses a double-layer silica gel nerve conduit. A silica gel conduit body is arranged on the innermost layer of the silica gel nerve conduit, a collagen conduit body is disposed on the outermost layer of the silica gel nerve conduit, and a fibrin glue layer is disposed between the silica gel conduit body and the collagen conduit body. The collagen conduit body is arranged on the outer layer of the silica gel conduit body, the portion between the collagen conduit body and the silica gel conduit body is filled with fibrin glue, the collagen conduit body and the fibrin glue are degradable, and accordingly damage is reduced. By means of the collagen conduit body, material exchange of the silica gel conduit body and the outside can be achieved. The conduit is further provided with an exchange layer to achieve material exchange of a silica gel layer and the outside, needed nutrients are provided, and a good treatment effect is guaranteed. A net-shaped decomposition layer and a spiral absorption layer are arranged, so that the silica gel layer is fully degraded and absorbed. As for patients with indwelling tubes after neurointervention embolization operations, harmful influences on human bodies caused by residual conduits can be reduced after release, and the harmful influences on the human bodies are avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a double-layer silicone nerve guide. Background technique [0002] Synthetic nerve conduit materials are divided into non-degradable and degradable materials; the most well-known non-degradable materials are silicone tubes, although they can show a good recovery effect on nerve sensation and movement in a short period of time, but silicone tubes cannot communicate with the outside world. Substance exchange cannot be absorbed by the human body, and staying in the human body for a long time will compress the nerves and affect nerve function, requiring reoperation to remove them. At present, the traditional silicone nerve guide has the problems that it cannot exchange substances with the outside world, affects nerve function, and has poor therapeutic effect. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a double-l...
