The invention discloses a method for preparing a medical collagen sponge, and relates to the technical field of medical biomaterial preparation. Main chemical components of a spider web are glycine, alanine and a small part of serine, added with other amino acid monomer protein molecular chains. Because sodium alginate is easily soluble in water, is a hydrophilic polymer, can absorb water and swell in a neutral aqueous solution, and has a strong water holding capacity, sodium alginate is partially oxidized by using sodium periodate to obtain oxidized sodium alginate containing aldehyde group.According to the method, the rigidity of the chain is reduced. Because of the introduction of the active group (the aldehyde group), the partially oxidized sodium alginate is chemically crosslinked with a polymer compound having a group such as an amino group to form a hydrogel. A collagen membrane is doped with degummed bamboo fiber, and pectin and lignin of the bamboo fiber are separated by hydrolysis after degumming, so as to form a bamboo fiber with an ultra-fine millipore structure. The flexibility and permeability of the collagen sponge are improved, and the application prospect is wide.
