SOFT TISSUE REPAIR PATCH AND PREPARATION METHOD THEREOF, AND TENSION-FREE HANGING BELT SYSTEM

摘要

A soft tissue repair patch, preparation method thereof, and tension-free hanging belt system; the soft tissue repair patch is a fibrous scaffold formed by fibers having diameters from 0.01 μm to 10 μm, and has a porous structure with a bulking value of 200-2000 cm3/g; and the fibers are fused together to form a fiber node at a joining position thereof. The preparation method of the soft tissue repair patch comprises: preparing a fiber film via an electrostatic spinning technique; and processing the fiber film to enable the fusion at the joining position of the fibers to form the fiber node. The tension-free hanging belt system comprises a hanging belt body and a protective sheath covering a surface of the hanging belt body; the hanging belt body is formed by fiber film layers, and has a hollow grid scaffold structure comprising a plurality of through holes; and a hole is provided on an upper surface or a lower surface of the protective sheath.
