23 Jul Degradable zinc alloy nerve conduit for repairing nerve deficiency and preparation method of degradable zinc alloy nerve conduit
Abstract
The invention discloses a degradable zinc alloy nerve conduit for repairing nerve deficiency and a preparation method of the degradable zinc alloy nerve conduit The nerve conduit is in a round pipe shape, the wall of the nerve conduit is provided with a plurality of columns of through holes, each column of through holes are equidistantly distributed along the axial direction of the round pipe, andthe adjacent columns of the through holes are distributed in a staggering manner; and two ends of the nerve conduit are respectively provided with a pair of large holes with a diameter of 0.3 to 0.5mm. A given number of holes are uniformly distributed on the wall of the conduit, so that the nutrition exchange between the peripheral nerves with deficiency and the peripheral tissues outside the conduit wall can be facilitated; and meanwhile, a give amount of holes are distributed on the conduit wall, an effect for regulating the degradation rate can be realized, and the matching of the regeneration time of the nerves and the degradation time of the conduit can be realized. The invention provides a clinical treatment scheme for bridging and repairing the nerve deficiency by virtue of a tissue engineering artificial nerves built by the zinc alloy conduit.
