The aim of this study is to analyze the operating force of the index finger during pressing a switch on the Electric Surgical Unit (ESU). The study about the kinematic and static characteristics of the index finger, which operates the ESU, has not been reported. The position of a switch on the ESU has been designed without evaluating the characteristics of the index finger driven model. The index finger posture which was measured by a three-dimensional motion analysis system and the tendon-muscle driven system of index finger were used to simulate the fingertip forces. The measured value of the fingertip force was recorded simultaneously using the force sensor. By comparing both results, extrinsic muscle has been the most effect of pressing a switch on the ESU.
