By summarizing the production practice and the improved calculation method, the relationship between radial pressure and the stress amplification factor of the medical gut was found, and an improved T/F calculation formula was obtained. The theory combined with the medical catgut processing model provides a design basis to solve the problem of low domestic product strength. According to the mechanical model, the gut-stripe breakage failure model can reasonably solve various defects in production, and can be used as a reference for the production of medical sutures.
