FIRING CIRCUIT AND CONTROL ALGORITHM FOR SURGICAL STAPLER
This abstract first appeared for US patent application 19002948 titled 'FIRING CIRCUIT AND CONTROL ALGORITHM FOR SURGICAL STAPLER
Original Abstract Submitted
A surgical instrument includes a body having a firing actuator, a shaft, a motor, an end effector, and a control circuit. The motor is configured to activate in response to a firing actuation of the firing actuator. The end effector is operable to staple and sever tissue and includes a cutting edge configured to selectively translate longitudinally between a proximal position and a distal position in response to an activation of the motor. The control circuit is configured to generate a forward motor control signal to pulsate the cutting edge. The forward motor control signal includes a first time duration including movement of the cutting edge distally from the proximal position to a second longitudinal position, a second time duration including ceased movement of the cutting edge, and a third time duration including movement of the cutting edge distally from the second longitudinal position toward the distal position.
