TENSION REGULATOR FOR ACTUATION ELEMENTS, AND RELATED REMOTELY ACTUATED INSTRUMENTS, SYSTEMS, AND METHODS

Abstract: a method of compensating for slack developing in an actuation element of a surgical instrument includes in response to slack developing in the actuation element, diverting the actuation element to follow a diverted path via a force exerted by an elastically deformable structure coupled to the actuation element. the diverted path differs from a path followed by the actuation element in a tensioned state, and the elastically deformable structure is moveable in translation together with the actuation element.
