Tissue repair material derived from fish skin and manufacturing method thereof
A tissue repair material derived from fish skin and manufacturing method thereof is applied to provide the tissue repair material suitable for use as a patch, a cover, a carrier, a scaffold, an implant or a reagent in various tissues. The tissue repair material has collagens to improve the wounded tissue repair, and has particular characters for desired tissue repair application. Furthermore, so far the factors of the terrestrial animal transmitted disease (caused by virus) do not survive on the tissue repair material derived from fish skin.
1. A tissue repair material derived from fish skin, comprises:
an optically clear flake derived from a fish skin, the optically clear flake being cell clean and comprising a collagen matrix and water in the collagen matrix, wherein the optically clear flake has a light transmittance larger than or equal to 70%, a ultimate stress larger than or equal to 5 MPa, and a sewability larger than or equal to 40 g.
2. The tissue repair material derived from fish skin according to claim 1 , wherein the collagen matrix is a layer structure formed with a plurality of collagen fibers, and each of the plurality of collagen fibers extends along a surface of the optically clear flake.
3. The tissue repair material derived from fish skin according to claim 1 , wherein the collagen matrix is a layer structure formed with a plurality of collagen fibers, and a part of the plurality of collagen fibers extends along a direction from a surface of the optically clear flake to another surface of the optically clear flake.
4. The tissue repair material derived from fish skin according to claim 1 , wherein the optically clear flake is derived from the fish skin completely without fish scales and a fish flesh.
5. The tissue repair material derived from fish skin according to claim 1 , wherein the optically clear flake is derived from the fish skin without grinding.
6. The tissue repair material derived from fish skin according to claim 1 , wherein the optically clear flake is made by a manufacturing method comprising removing fish scales, oil, cells, chromatophores and pocket structures from the fish skin to obtain a purified fish skin, treating the purified fish skin with first acidic solution to obtain a shapeable flake without breakdown, shaping the shapeable fish skin to obtain a shaped flake in a particular form, and performing a stabilization procedure to stabilizing the shaped flake.
