The invention provides a degradable tissue repair material. The degradable tissue repair material comprises a recombinant spider silk protein. The amino acid sequence of the recombinant spider silk protein is shown in SEQ ID NO.1; according to the recombinant spider silk protein, by inserting a protease digestion locus between two adjacent spider silk protein structural domain monomers, when the recombinant spider silk protein is in use inside a human body, due to the fact that the protease digestion locus on the recombinant spider silk protein can be enzymatically hydrolyzed by an enzyme inside the human body, the biological material manufactured by the recombinant spider silk protein can be gradually degraded inside the human body, accordingly, the recombinant spider silk protein is usedas a raw material for preparing the tissue repair material, it is ensured that the repair material has the degrading performance while the mechanical performance or the biological quality of the existing spider silk protein is ensured, and the clinic requirement is met.
