An apparatus for operating on tissue comprises a shaft, an acoustic waveguide, and an end effector. The acoustic waveguide extends along the shaft and is configured to transmit ultrasonic vibration. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The clamp arm is pivotable toward the ultrasonic blade. The end effector defines a first longitudinal region and a second longitudinal region. The end effector is configured to clamp tissue between the clamp arm and the ultrasonic blade in the first longitudinal region. The end effector is configured to sever tissue with the ultrasonic blade in the second longitudinal region.
The invention relates to a device (1) for producing clamps (3) bent from wire sections (2), in particular surgical clamps, having a bending device (22) for bending a wire section (2), having a feed device (4) for a wire (5) having a cutting device (6) for separating a wire section (2) from the fed wire (5). The cutting device (6) has two cutting stamps (11) for cutting the wire (5). A holding device (14) is provided for gripping and holding the wire section (2) between the two cutting stamps (11) before separating the wire section (2) and for positioning the separated wire section (2) on a bending device (22) and for feeding the wire section (2) bent into the clamp to a device (33) for inserting the clamp (3) into a cartridge (34) or a clamp storage (35).
A medical instrument lockout comprises a slidable linkage having a first link and a second link, and a first fixed pivot and a second fixed pivot. The second link is pivotable about the second fixed pivot to pivot the first link about the first fixed pivot. Pivoting of the second link about the second fixed pivot may disengage the first link from an extendable member. A spring may be positioned to bias the first link against the extendable member to lock the instrument. The spring may be deflected by the first link when the second link pivots about the second fixed pivot to disengage the lock.
An end effector comprises a first jaw, a second jaw, a firing beam, and a lockout feature. The second jaw pivots relative to the first jaw from an open position to a closed position. The firing beam has a sharp distal end and translates between the first and second jaws. The firing beam translates from a proximal position to a first distal position to pivot the second jaw to the closed position. The end effector applies bipolar RF energy when the firing beam is in the first distal position. The firing beam then translates to a second distal position to sever tissue captured between the first and second jaws. The lockout feature prevents the firing beam from advancing from the first distal position to the second distal position until the lockout feature is actuated.
An apparatus for operating on tissue comprises an end effector, a shaft assembly, and an interface assembly. The end effector comprises an ultrasonic blade. The shaft assembly includes an articulation section operable to deflect the end effector away from the longitudinal axis. The interface assembly is operable to drive the end effector. The interface assembly comprises a base and a plurality of drive shafts. The base is configured to couple with a dock of a robotic control system. The drive shafts are oriented perpendicular to the longitudinal axis of the shaft assembly. A first drive shaft may be operable to rotate the shaft assembly relative to the base.

The blade assembly translates relative to the first jaw and includes a first tab (268). The lockout assembly includes a resilient member (280) that biases the blade assembly to a lockout position. The lockout assembly engages the first tab of the blade assembly in the lockout position to prevent the blade assembly from translating distally relative to the first jaw when a staple cartridge is absent from the first jaw or when a spent staple cartridge is disposed in the first jaw.

SURGICAL INSTRUMENT WITH ARTICULATION LOCK HAVING A DETENTING BINARY SPRING
A apparatus includes a shaft, an end effector, an articulation joint, and a locking feature. The end effector is pivotable from a first position to a second position.
