Abstract
A surgical system is disclosed. The surgical system comprises an end effector configured to move through a grasping motion, a motor configured to drive the grasping motion, an encoder configured to detect rotary positions, a load sensor configured to detect loads delivered, a position sensor configured to detect three-dimensional positions of the end effector, and a control circuit configured to receive a position parameter, a rotary parameter, and a load parameter, store the position parameter at the outset of the grasping motion, calculate an amount of work performed during the grasping motion while the position sensor detects the position of the end effector within a three-dimensional zone around the stored position parameter, transmit a work signal indicative of the amount of work performed, and reset the calculation of the amount of work performed when the position sensor detects a displacement of the end effector out of the three-dimensional zone.
