An apparatus comprises an electrically power surgical instrument having a handle assembly. The apparatus also comprises a communication device positioned within the handle assembly. The communication device is operable to communicate with at least a portion of the electrically powered surgical instrument. The apparatus further comprises an external device in wireless communication with the communication device. The external device is operable to receive information from the communication device and the external device is operable to provide an output viewable to the user.

A surgical instrument that comprises an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective pivotal travel relative thereto about an articulation axis that is laterally offset from the shaft axis and extends transversely relative thereto. An end effector driver link is operably coupled to the surgical end effector and an articulation driver that is supported for longitudinal travel in distal and proximal directions upon application of articulation motions thereto. A flexible de-articulation member is coupled to the elongate shaft assembly and the surgical end effector to apply de-articulation motions to the surgical end effector.

A surgical instrument includes a housing and an elongated shaft having a distal portion and a proximal portion coupled to the housing. The elongated shaft defines a longitudinal axis and a mandrel at the proximal portion. An inner shaft member extends at least partially through the elongated shaft. An actuating mechanism is operably coupled to the mandrel and is configured to selectively cause movement of the elongated shaft in a longitudinal direction with respect to the inner shaft member. The surgical also includes an end effector that is adapted for treating tissue and includes an upper jaw member pivotally coupled to a distal portion of the inner shaft member about a pivot axis and a lower jaw member supported by the distal portion of the elongated shaft. Longitudinal movement of the elongated shaft is configured to pivot the upper jaw member relative to the lower jaw member.

An adapter assembly for operably connecting an end effector to an electromechanical surgical instrument includes a drive transfer assembly, a drive member, and a first pusher assembly. The drive transfer assembly includes first and second rotatable shafts. The drive member is operably connected to the first rotatable shaft for transferring rotational motion from the first rotatable shaft to effect a first function and the first pusher assembly is operably connected to the second rotatable shaft for converting rotational motion from the second rotatable shaft to longitudinal movement to effect a second function. The first pusher assembly includes a brake member for rotationally locking the drive member relative to the first pusher assembly.

An ultrasonic surgical device comprises a handle assembly, a shaft assembly, and a removable transducer module. The transducer module includes a waveguide, a locking mechanism, and an electronics assembly including at least one button. The handle assembly includes a trigger assembly configured to actuate the button(s) of the electronics assembly when the transducer module is coupled with the handle assembly. The shaft assembly engages the waveguide of the transducer module and is disposed at the distal end of the handle assembly. The distal end of the shaft assembly includes a harmonic blade. When assembled with the handle assembly, the transducer module is capable of providing ultrasonic energy to the harmonic blade.

A surgical instrument. In one form, the surgical instrument comprises a first jaw and a second jaw that is movably supported relative to the first jaw for selective movement between open and closed positions relative to the first jaw. A firing drive shaft is rotatably supported in one of the first and second jaws. A firing member operably interfaces with the firing drive shaft for selective axial travel in response to rotation of the firing drive shaft. The surgical instrument further comprises a distal power shaft that is separate and distinct from the firing drive shaft and is configured for selective operable engagement with the firing drive shaft. A closure member is supported for axial travel on a proximal end portion of the first jaw and is configured for selective threaded engagement with a portion of the distal power shaft.

An apparatus includes a body assembly, a shaft defining a longitudinal axis extending from the body assembly, an acoustic waveguide having a flexible portion, and an articulation section coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section has a first member and a second member translatable relative to the first member. An end effector has an ultrasonic blade that is in communication with the waveguide. An articulating control assembly has a motor. The motor is operable to translate the first and second members to thereby deflect the end effector away from the longitudinal axis at the articulation section.

An end effector for use with a surgical fastening instrument is disclosed which comprises a staple cartridge and an anvil. The staple cartridge comprises a cartridge body including a deck and, in addition, fasteners removably stored in the cartridge body, wherein each fastener comprises a base and a leg extending from the base. The anvil comprises a tissue compression surface and forming pockets defined in the tissue compression surface. Each forming pocket comprises a first end configured to receive a staple leg, a second end, a central axis extending between the first end and the second end, a concave turning surface extending between the first end and the second end, and a channel defined in the concave turning surface, wherein the channel is laterally offset from the central axis.

A surgical instrument is disclosed. In one form, the surgical instrument comprises an elongate shaft assembly and an end effector that is configured for selective rotation relative to the axis of the elongate shaft assembly. The surgical instrument can include a rotary locking system for locking the surgical end effector in rotary orientations about the shaft axis upon application of axial locking and axial unlocking motions to the rotary locking system. The surgical instrument may further comprise a rotary drive system that is configured to apply rotary control motions to a firing member as well as to apply rotary positioning motions to the surgical end effector.
