Ptmc-based intestinal anastomosis stent of bioabsorbable flexible elastomer and preparation method therefor

Abstract

A PTMC-based intestinal anastomosis stent of a bioabsorbable flexible elastomer and a preparation method therefor. The intestinal anastomosis stent that uses PTMC as a base material is prepared by using an electrospinning method, and an appropriate range suitable for being implanted into the body is screened out according to a degradation rate and a mechanical property. The stent is loaded with TCS having a bactericidal effect, so that the stent has a tissue repair adjustment function, enabling a wound to heal more quickly in a severe multi-bacterial intestinal environment, and for adjusting postoperative tissue healing and functional repair. An in-vivo animal intestinal anastomosis experiment is carried out, thus verifying the practical effects and the feasibility of the method.
