Abstract: An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

Abstract: A surgical system is disclosed including impedance sensors and a control circuit. The impedance sensors are configured to apply a therapeutic level of RF energy to tissue, sense a real time impedance of the tissue, sense a first tissue impedance based on an initial contact with the tissue, sense a second tissue impedance of the tissue without applying a therapeutic amount of RF energy to the tissue. The control circuit is configured to determine a control parameter of a motor based on the first tissue impedance and the second tissue impedance, determine a percentage of use of an end effector, detect a change of the real time impedance of the tissue, adjust the control parameter of the motor based on the change of the real time impedance and the percentage of use of the end effector, and control delivery of a therapeutic energy application to the tissue.

Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

Abstract: A loading unit coupleable to a surgical stapling system is disclosed. The loading unit comprises an end effector, a firing system, and a shaft assembly extending proximally from the end effector. The end effector comprises a first jaw and a second jaw movable relative to the first jaw between an open position and a clamped position. The firing system comprises a firing assembly and an indicator. The firing assembly is movable toward a distal position through the end effector in response to a firing motion from the surgical stapling system. The indicator is configured to visually communicate a position of the firing assembly to a user of the surgical stapling system. The shaft assembly is removably couplable with the surgical stapling system and comprises an open slot region aligned with the firing assembly. The open slot region extends proximally with respect to the second jaw.

Abstract: Disclosed are ultrasonic and electrosurgical devices. The disclosed embodiments include a surgical instrument comprising a waveguide, and end effector and an electrical switch. The waveguide may comprise a proximal end and a distal end, wherein the proximal end is configured to couple to an ultrasonic transducer and one output of a radio frequency (RF) generator. The end effector may comprise an ultrasonic blade and a clamp arm coupled. The ultrasonic blade may be mechanically coupled to the distal end of the waveguide and electrically coupled to the waveguide. The clamp arm may comprise a movable jaw member electrically coupled to another output of the RF generator such that an electrical current can pass through the movable jaw member and the ultrasonic blade through tissue located between the movable jaw member and the ultrasonic blade. The electrical switch may be configured to electrically couple to the RF generator and the movable jaw member, wherein the switch is operable to cause the surgical instrument to deliver electrical current from the RF generator to the movable jaw member for a first period, and to cause the surgical instrument to deliver ultrasonic energy to the ultrasonic blade for a second period.
