More Information
Summary:Disclosed herein is an asymmetric rolling joint device of a surgical instrument which increases traction force by asymmetrically forming rolling contact surfaces of joint links facing each other. The asymmetric rolling joint device includes: a first joint link part which forms a joint of the surgical instrument; and a second joint link part coming into rolling contact with the first joint link part, wherein rolling contact surfaces where the first joint link part and the second joint link part come into rolling contact with each other are formed asymmetrically so as to increase traction force more than rolling contact surfaces which are formed symmetrically.
