Abstract: This study proposed the use of the minimum slip force as an indicator to measure the clamping ability of microsurgical forceps.By analyzing the minimum slip forces of four typical tooth types of microsurgical forceps,the clamping capacity of each type was evaluated.Among the existing tooth forms,the staggered tooth type exhibited a relatively large minimum slip force.Consequently,a new tooth-shaped structure for microsurgical forceps-the hemispherical convex structure was proposed.Simulation and experimental studies demonstrated that this new dental structure could achieve stable and reliable clamping.
