3 results about "Tissue repair" patented technology

The invention discloses a guided tissue regeneration membrane. The membrane adopts a double-layer membrane structure and is characterized in that one layer is a compact layer prepared from biological fibers with longer degradation time, and the other layer is a potential loose layer prepared through mixing of biological fibers with different degradation time. After the potentialloose layer is implanted in a body, part of the biological fibers degrades quickly, so that the pore diameter of the membrane is increased, and ingrowth of cells is facilitated. The compact layer and the potential loose layer are connected through the same biological fibers with the longer degradation time, so that the double-layer membrane is free of splitting and fractures. The invention further discloses a preparation method of the guided tissue regeneration membrane as well as an application of the guided tissue regeneration membrane as a tissue repair product to tissue repair.
