Through the machine woven artificial trachea, the radial supporting performance of the machine woven artificial trachea is guaranteed, the design and operating difficulty of the prior art is simplified, and a differentiable machine woven artificial trachea can be quickly and conveniently obtained by varying different binding tissues and basic tissues.
Description
Technical field
The present invention relates to a kind of woven artificial trachea, belong to medical artificial human organ technical field.
Background technology
Artificial trachea is to knit the netted tube that forms of system with medical macromolecular materials, replaces the tracheae or the part bronchus that have excised because of cancer or unexpected injury.Artificial trachea can or grow into tissue with the organization healing that links to each other, and can bear the distortion that pressure caused from surrounding tissue.The ubiquitous problem of woven artificial trachea is radially powerful not enough.Present solution is fixing again spiral elasticity filiform in common artificial trachea outside.Though adopt this method can improve the radially powerful of artificial trachea, elastic fixing loaded down with trivial details; And manufacturing process need implement step by step, and control is difficulty relatively.
Summary of the invention
The purpose of this invention is to provide the radially powerful and artificial trachea simple to operate of a kind of raising.
In order to achieve the above object, a technical scheme of the present invention has provided a kind of woven artificial trachea, it is characterized in that; Comprise inner layer tube wall and outer wall, inner layer tube wall and outer wall adopt double-layered structure or heavy latitude tissue, when adopting double-layered structure; By multifilament as internal layer warp thread and internal layer weft yarn, internal layer warp thread and the internal layer weft yarn inner layer tube wall that is interwoven, by monofilament as outer warp thread and outer weft yarn; Outer warp thread and the outer weft yarn outer wall that is interwoven adopts access node tissue tight to link together between inner layer tube wall and the outer wall, constitute an integral body; When adopting heavy latitude to organize, by multifilament as the internal layer weft yarn, by monofilament as outer weft yarn; At last by multifilament as warp thread, an integral body is interwoven.
Further, said multifilament is medical polymer biological degradable multifilament or medical polymer biological non-degradable multifilament.
Said monofilament is medical polymer biological degradable monofilament or medical polymer biological non-degradable monofilament.
The present invention proposes a kind of structure of novel artificial tracheae, this structure can one-shot forming, elastic strands directly knit artificial trachea skin, on technology, simplified the difficulty of operation, help promoting the use of of woven artificial trachea.
In sum, the present invention has guaranteed the radial support performance of woven artificial trachea; Simplified the design operation difficulty of prior art; Through changing the woven artificial trachea that different access node tissues and basic organization can obtain differentiation quickly and easily.
