FIELD: medicine.
SUBSTANCE: invention refers to medicine. An electrically driven surgical cutting and stapling instrument comprises an end effector, a shaft connected to the end effector, and a handle connected to the shaft. The end effector comprises a cutting instrument, which when actuated moves longitudinally along the end effector for cutting tissue. The handle comprises an electric drive actuating the cutting instrument and an electric drive control circuit. The control circuit comprises a power source and a current setting circuit. The current setting circuit can vary a torque on an output shaft.
EFFECT: electric drive has at least the first low-power working mode for the first section of the cutting travel cycle of the cutting instrument and the second high-power working mode for the second section of the cutting travel cycle of the cutting instrument.
