Method for manufacturing material for repairing human tissue by adopting autologous fingernails

Abstract

The invention provides a method for manufacturing a material for repairing the human tissue by adopting autologous fingernails. The method mainly comprises the following steps: washing the autologous fingernails to be clean, carrying out disinfecting and sterilizing on the washed autologous fingernails, dehydrating the fingernails until the water content is less than 50%, immersing the dehydrated fingernails into liquid nitrogen, grinding the fingernails by adopting a grinder until the particle diameter is less than 5000 [mu] m, and screening the particles by adopting a sieve so that matrix and powder are separated, wherein the powder can be used as the material for repairing the human tissue. The powder biological material manufactured by adopting the method provided by the invention is rich in collagen, collagen is the important substance for maintaining the human tissue structure, the powder biological material is manufactured by adopting the autologous fingernails, so as to be easily absorbed by the human body, the host immune response can not be caused, further, the danger of rejection or infection is avoided, in addition, the acquisition source is simple, so that the material can be used as the most ideal material for human tissue repair or tissue transplantation, or other purposes.

Description

Technical field [0001] The present invention relates to a method for using autologous nails to make materials for repairing human tissues, in particular to a nail that can be obtained from autologous nails after being washed, dehydrated, and ground into powder for use in tissue repair or tissue transplantation. The material that can be easily absorbed by the human body and can be quickly restored. Background technique [0002] Collagen is an important substance to maintain the structure of human tissues. For example, the cornea, bones, ligaments, cartilage, skin, etc. in human tissues and organs are rich in collagen. Therefore, if the above-mentioned tissues and organs are damaged or transplanted, The usual practice is to supplement a large amount of collagen to absorb and repair, so as to restore the original healthy state. Generally, collagen can be obtained from natural ingredients. It is usually extracted from animals, livestock or fish. However, the collagen extracted by th...

Problems solved by technology

In addition to obtaining natural ingredients, collagen is usually extracted from animals, livestock or fish. However, the collagen extracted through the above methods cannot be guaranteed to be absolutely safe. There are often various problems such as infectious bacteria or fishy smell, and after entering the human body, it may not be absorbed by everyone, and it may also trigger the host’s immune response, often causing rejection or infection, which is not ideal.
