23 Jul Bio-absorbable high-molecular nerve conduit skeleton and preparation method thereof
Abstract
The invention discloses a bio-absorbable high-molecular nerve conduit skeleton and a preparation method of the bio-absorbable high-molecular nerve conduit skeleton, belonging to the technical fields of biomedical materials and tissue engineering. The bio-absorbable high-molecular nerve conduit skeleton is of a tubular structure, the inner diameter of the tubular structure is 1.2-4.8 mm, the aperture of the inner-layer tube wall of the tubular structure is 0.3-10 [mu] m, and the outer-layer aperture is 20-100 [mu] m; the bio-absorbable high-molecular nerve conduit skeleton contains poly epsilon caprolactone, poly L-lactic acid and polyhydroxyalkanoate, the conduit skeleton is prepared by adopting poly epsilon caprolactone, poly L-lactic acid and polyhydroxyalkanoate, the strength and hardness of the nerve conduit skeleton are improved, and the added poly epsilon caprolactone can improve the elasticity of the nerve conduit skeleton, so that the nerve conduit skeleton can meet the radial support requirement; according to the preparation method of the nerve conduit skeleton provided by the invention, the degradation rate of the nerve conduit skeleton is controllable, the preparation is convenient, and the operability is good.
