Abstract In view of the reliability of the tensile ability of the clinical adhesive after suturing the skin wound, the tensile properties of the skin suturing interface prepared by silica gel reverse molding process were studied. Based on the study of the tensile stiffness of four types of stitched structures, the equivalent mechanical model of the skin interface was constructed using the mechanical theory of the stitched interface, and the mathematical model for predicting the tensile stiffness was obtained. Combined with numerical simulation and physical experiment, the influence of shape factor and tooth tip Angle on the tensile properties of skin suture structure was analyzed, and the influence of tip area proliferation on the tensile properties of interface structure was further explored. The results showed that the zigzag structure had significant tensile stiffness compared with other suture structures, and the stiffness of the four types of suture structures showed a decreasing trend with the increase of the tooth cusp Angle, and the tip area further improved the tensile properties of the suture interface, which could provide relevant references for improving the healing rate of skin wounds after clinical suture.
