Abstract
A teleoperated surgical system includes a surgical instrument with an end effector and a master input device. A servomechanism may be operatively coupled to the end effector to apply a force to the end effector, and at least one processor may operatively couple the servomechanism to the master input device to apply a grip force with the first and second gripping elements in response to input at the master input device. The applied grip force may be based at least in part on a mechanical advantage of the surgical instrument end effector.
