Abstract: An ultrasonic surgical instrument includes a body, an ultrasonic supported by the body, a shaft extending distally from the body and defining a shaft axis, a waveguide extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade coupled to a distal end of the waveguide and having a primary blade treatment surface configured to treat tissue, and a clamp arm coupled to the distal end of the shaft. The shaft and the waveguide are selectively rotatable relative to one another about the shaft axis through a predefined range of angular motion between an assembly state and an operational state. In the assembly state, the clamp arm and the primary blade treatment surface are rotationally offset from one another. In the operational state, the clamp arm and the primary blade treatment surface are rotationally aligned.

Abstract: A surgical instrument includes a gripping assembly, a shaft assembly, an end effector, and a pivoting member. The gripping assembly defines a first opening for receiving a finger or a thumb of a user. The gripping assembly includes a first deformable feature that is configured to be moved in order to increase or decrease a cross-sectional area of the first opening. The shaft assembly extends distally from the gripping assembly. The end effector is positioned at a distal end of the shaft assembly and includes a first member. The pivoting member is pivotably coupled with the shaft assembly. The pivoting member is pivotable with respect to the first member of the end effector between an open position and a closed position to thereby clamp tissue between the first member and the pivoting member.

Abstract: Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.

Abstract: A variety of methods for managing a re-usable ultrasonic medical device may include a medical device control module capable of receiving functional data from a user assembled or reassembled ultrasonic medical device, and notifying the user if a value of the functional data lies within an acceptance range. If the value of the functional data does not lie within the acceptance range, the control module may prompt a user to reassemble the device or to clean or replace one or more components thereof. The functional data may relate to a clamp force of a jaw assembly, an impedance or resonant frequency value of an ultrasonic blade, or a mechanical displacement value of one or more moving components of the device.

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: Various embodiments are directed to a method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument. The method comprises generating at least one electrical signal. The at least one electrical signal is monitored against a first set of logic conditions. A first response is triggered when the first set of logic conditions is met. A parameter is determined from the at least one electrical signal.

Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.
