Abstract

A modified Reynolds equation is derived from the property of human body´s lumen that is non-Newton fluid. A motion model is built for the spiral-grooved medical micro-robot working inside the lumen of human body. Based on the finite difference method, the relationship between the spiral-grooved parameters and kinetic properties such as the load capacity of hydrodynamic pressure, the axial thrust force and the circumferential resisting force is analyzed theoretically. Consequently, the optimal parameters of the spiral grooved medical micro-robot are obtained.
