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 manufacturing method of a tissue repair material derived from fish skin, comprises:
obtaining a fish skin without a fish flesh;
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 acidic solution to obtain a shapeable flake without breakdown; and
shaping the shapeable fish skin to obtain a shaped flake in a particular form, wherein the shaping step comprises cutting the shapeable flake to obtain the shaped flake, wherein a surface of the shaped flake is a cross section of the shapeable flake.
2. The manufacturing method according to claim 1 , further comprising washing the shaped flake with water.
3. The manufacturing method according to claim 2 , further comprising dehydrating the shaped flake before the washing step.
4. The manufacturing method according to claim 2 , further comprising dehydrating the shaped flake after the washing step.
5. The manufacturing method according to claim 4 , further comprising backwatering the shaped flake after the dehydrating steps.
6. The manufacturing method according to claim 5 , further comprising dehydrating the shaped flake after the backwatering step.
7. The manufacturing method according to claim 1 , further comprising:
extracting a collagen solution from the shapeable flake.
8. The manufacturing method according to claim 1 , further comprising:
lyophilizing the shapeable flake.
9. The manufacturing method according to claim 1 , wherein the treating step comprises:
treating the purified fish skin with acidic solution more than two times to obtain the shapeable flake without breakdown;
removing at least one outer layer of the shapeable flake between any two acid-treating steps.
