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.
提出采用最小滑脱力作为度量显微手术镊夹持能力的指标。针对现有的4种典型的显微手术镊牙型,利用Abaqus软件进行有限元建模。在分析4种牙型的最小滑脱力的基础上,对其夹持能力进行了评估。在现有的牙型中,交错齿型具有较大的最小滑脱力。在此基础上,提出了一种显微手术镊的新的牙型结构-半球凸起结构。仿真和实验研究表明,新的牙型结构可实现稳定、可靠的夹持。.
