[0029] Such as figure 1 As shown, a strip-shaped composite material for internal fixation of tendon carrying transgenic cells, the composite material is composed of an outer layer of non-degradable tendon surface internal fixation polyester material layer 1 and an inner layer of pharmacologically acceptable The biodegradable matrix film material layer 2 rich in micropores is compounded. The non-degradable polyester material layer 1 internally fixed on the surface of the tendon is composed of inner and outer layers, and the outer layer is made of polyethylene terephthalate, which is rich in microporous polyethylene terephthalate. Ethylene formate film 11 (nano-scale pores are evenly distributed on the film, and the hole density is 4500 / mm 2 , the pore diameter is about 0.6nm, and the thickness is 20μm), and its inner layer is a polyethylene terephthalate network structure 12 (thickness is 1.1mm) made of polyethylene terephthalate. The matrix material of biodegradable matrix f...
