This paper investigates the friction characteristics of the instrument / trocar interface in laparoscopic surgery for varying linear instrument velocities , trocar seal design and material , and trocar tilt . Further , the effect of applying lubrication at the instrument / trocar seal interface on friction was studied . A friction testing apparatus was designed and built to characterise the resistance force at the instrument / trocar interface as a function of the instrument ’ s linear movement in the 12 mm trocar ( at constant velocity ) for different design , seal material , and angle of tilt . The resistance force depended on the trocar seal design and material properties , specifically ; surface roughness , elasticity and hardness , the direction of movement and the instrument linear velocity , and varied between 0.25 and 8 N . Lubricating the shaft with silicone oil reduced the peak resistance force by 75% for al trocars and eliminated the stick - slip phenomenon eVident in non - lubricated cases . The magnitude of fluctuation in resistance force depends on the trocar design and is attributed to stick - slip of the sealing mechanism , and is generaly higher during retraction in comparison to insertion . Trocars that have an inlet seal made of rubber / polyurethane showed higher resistance forces during retraction . Use of a lubricant significantly reduced frictional effects . comparisons of the investigated trocars indicate that a low friction port , providing the surgeon with improved haptic feedback , can be designed by improving the tribological properties of the trocar seal interface .
