Abstract
A surgical instrument includes an end effector, a motor for opening and closing the jaws, a sensor configured to detect a tissue compression parameter associated with a tissue between the jaws, and a control circuit. The control circuit is configured to determine a value of the tissue compression parameter via the sensor as the jaws transition from the open configuration to the closed configuration, cause the motor to increase a time to transition the jaws to the closed configuration according to whether the value of the tissue compression parameter is above a first threshold, and provide feedback according to whether the value of the tissue compression parameter is below a second threshold.
