Abstract: Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

Abstract: A control circuit for a surgical instrument includes a shaft control segment, a first electrical conductor configured to conduct a first electrical signal between the shaft control segment and a releasable surgical instrument cartridge, an electrosurgical energy control segment, a second electrical conductor configured to conduct a second electrical signal between the electrosurgical energy control segment and the releasable surgical instrument cartridge, and a connector electrically coupled to the electrosurgical energy control segment and configured to receive electrosurgical generator energy from an electrosurgical generator. The electrosurgical energy control segment is configured to detect a connection of the electrosurgical generator to the connector and to electrically isolate the shaft control segment from the electrosurgical generator energy when the electrosurgical energy control segment detects the connection of the electrosurgical generator to the connector.

Abstract: A method of controlling motor velocity in a surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer coupled to the control circuit. The method includes receiving a first position of a displacement member from a position sensor, starting a timer, advancing the displacement member to a second position by setting a motor velocity to a first velocity, receiving the second positon from the position sensor, stopping the timer when the displacement member reaches the second position, receiving elapsed time from the timer, wherein the elapsed time is the time taken by the displacement to move from the first position to the second positon, and controlling, by the control circuit, velocity of the motor based on the elapsed time.

Abstract: A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member configured to translate over a plurality of predefined zones. A motor comprising a shaft is coupled to the displacement member. 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 zone defined by a set rotation interval, measure time at a set position of the rotation interval, wherein the measured time is defined as the time taken by the displacement member to traverse the rotation interval based on a predetermined number of shaft rotations, and set a command velocity of the displacement member for a subsequent zone based on the measured time in the current predefined zone.

Abstract: An apparatus comprises a first jaw, a second jaw, a first handle, and a second handle. The second jaw is pivotally coupled with the first jaw. The first jaw and the second jaw are configured to grasp tissue. The jaws provide offset electrode surfaces that are operable to deliver bipolar RF energy to tissue grasped between the jaws. The apparatus is further operable to sever tissue. A lockout feature selectively prevents tissue severing, based on an energization state of the jaws.
