Adaptation of independent firing and closure powered stapling systems
A surgical instrument is disclosed including a motor-powered firing system comprising a firing motor, a motor-powered closure system comprising a closure motor, and a control system. The firing motor is configured to drive a firing member between an unfired position and a fired position. The closure motor is configured to transition an end effector between an open state and a clamped state. The control system is configured to set a first parameter of the motor-powered closure system, based on a received first input, drive the end effector toward the clamped state with the motor-powered closure system using the first parameter, monitor a second parameter associated with the end effector transitioning toward the clamped state, set a third parameter of the motor-powered firing system, based on a received second input and the monitored second parameter, and drive the firing member toward the fired position using the third parameter.

Adaptive knife-based closure methods for surgical stapler
An apparatus (1000) includes an end effector (200), a motor (1100), a sensor (1104), and a controller (1150). The end effector includes first and second jaws (202, 204) and a knife (206).

The controller determines whether the first force value exerted by the motor exceeds a first predetermined force threshold as the knife is contacting the ramp surface. The controller is configured to alter travel of the knife. Altering the travel of the knife includes at least one of: pausing the knife for a predetermined amount of time, pausing the knife until a second force value exerted by the motor obtained from the sensor is below the first predetermined force threshold, or advancing the knife at a second speed that is less than the first speed.
