CLOSED-LOOP FEEDBACK CONTROL OF THE MOTOR SPEED OF A SURGICAL STAPLING AND CUTTING INSTRUMENT ON THE BASIS OF A MEASURED TIME ON A SPECIFIED NUMBER OF TREE ROTATIONS |
abstract |
The present invention relates to a motorized surgical instrument. The surgical instrument includes a displacement member configured to translate over a plurality of predefined areas. An engine comprising a shaft is coupled to the displacement element. A control circuit is coupled to the motor. A position sensor is coupled to the control circuit to monitor the rotation of the shaft. A timer circuit is coupled to the control circuit. The control circuit is configured to receive rotations of the shaft in a current area defined by a defined rotation interval, measure the time at a defined position of the rotation interval, the measured time being defined as the time required the displacement element for traversing the rotation interval on the basis of a predetermined number of shaft rotations, and setting a control speed of the displacement element for a subsequent area on the basis of the time measured in the predefined area. |
