Abstract

The invention relates to a slow-release and anti-infective composite soft tissue repair material and a preparation method thereof. The repair material is prepared from a biological material and media containing anti-infective components, wherein the media containing the anti-infective components are arranged between layers of the biological material or on the surface of the biological material at intervals according to the radius of an inhibition zone of a drug sensitive test, and a whole body is formed by the aid of a binding agent, suture lines or pressure. According to the slow-release and anti-infective composite soft tissue repair material and the preparation method thereof, the anti-infective components can be released effectively and continuously, meanwhile, biocompatibility of the biological material is not changed, the biological material is non-toxic and harmless, and the application prospect is good.

Description

technical field

[0001] The invention belongs to the field of soft tissue repair materials and preparation thereof, in particular to a slow-release anti-infection composite soft tissue repair material and a preparation method thereof. Background technique

[0002] Biomaterials are an important advance in the study of soft tissue repair materials. Representative materials that are resistant to infection and remodelable include synthetic biomaterials (such as P4HB, silk fibroin fibers, collagen, chitosan, etc.) and acellular matrix biomaterials. Compared with traditional non-absorbable polymer materials, biomaterials act as temporary tissue scaffolds after implantation in the body, and as the patch material degrades, host cells infiltrate it and produce autologous collagen fibers. Such an endogenous tissue remodeling process can achieve early local rapid revascularization, early entry of phagocytes, and difficulty in the formation of bacterial biofilms, so it has a certain resi...
