A Preliminary Study on the Design of Compliant Surgical Gripper Jaw

The study evaluates on the mechanical design and dimensional synthesis for pseudo-rigid-body model (PRBM) and finite element analysis (FEA) on a compliant constant-force surgical gripper. Polyethylene Terephthalate (PET), Polylactide (PLA) and Polypropylene Co-polymer (PPC) were selected for the analysis of output force, flexural pivot stress and deflection for both methods. The study found that the output force computed from PRBM and FEA method has the difference of about 30% for PET and PLA material, while the flexural pivot stress computed between PRBM and FEA method is less than 15 %. It was also revealed that maximum deflection occurred at the flexure hinge between the slider and crank of the compliant surgical gripper jaw.
