Abstract: Propose using the minimum slip force as an indicator to measure the clamping ability of microsurgical forceps. Based on the analysis of the minimum slip force of the four typical microsurgical tweezers tooth types, the clamping capacity of the four types of teeth was evaluated. Among the existing tooth forms, the staggered tooth type has a relatively large minimum slip force. On this basis, a new dental structure for microsurgical forceps, the hemispherical protrusion structure, was proposed. Simulation and experimental studies have shown that the new dental structure can achieve stable and reliable clamping.
