The staple driver actuator further includes at least one rail extending upwardly from the base. The rail includes at least one first cam surface. The first cam surface is inclined relative to the plane, and the first cam surface is longitudinally aligned with at least a portion of the at least one top surface.

A slip ring assembly is used with a surgical shaft assembly. The slip ring assembly includes a slip ring, a first conductor mounted on the slip ring, a commutator rotatable relative to the slip ring, and a second conductor mounted on the commutator. The slip ring assembly further includes a flexible member disposed between the slip ring and the commutator. The flexible member comprises a body and flexible protrusions extending from the body, wherein the flexible protrusions are elastically deformed against the first slip ring.

A surgical system includes a control circuit, a surgical instrument, and a user interface is disclosed. The surgical instrument includes a plurality of components and a sensor. Each of the plurality of components of the surgical instrument includes a device parameter and is configured to transmit its respective device parameter to the control circuit. The sensor of the surgical instrument is configured to detect a tissue parameter associated with a proposed function of the surgical instrument, and transmit the detected tissue parameter to the control circuit. The control circuit is configured to analyze the detected tissue parameter in cooperation with each respective device parameter based on a system-defined constraint. The user interface is configured to indicate whether the surgical instrument comprising the plurality of components is appropriate to perform the proposed function.

A surgical stapling instrument is disclosed. An end effector for the surgical stapling instrument comprises a staple cartridge assembly and an anvil. The staple cartridge assembly comprises a proximal end, a distal end, and a cartridge body comprising a shortened nose at the distal end. The staple cartridge assembly further comprises staples removably stored in the cartridge body, a driver configured to support at least one of the staples, and a sled movable toward the distal end. The sled comprises a ramp configured to lift the driver and at least one of the staples and a base, wherein the shortened nose of the cartridge body is shorter than the base of the sled. The anvil comprises a staple forming surface comprising a plurality of staple forming pockets and a blunt distal nose extending downward toward the staple cartridge assembly.

A surgical instrument connectable to a surgical energy module that is configured to provide a first drive signal at a first frequency range for driving a first energy modality and a second drive signal at a second frequency range for driving a second energy modality is provided. The surgical instrument can comprise a surgical instrument component configured to receive power from a direct current (DC) power source, an end effector, and a circuit. The circuit can be configured to convert the first electrical signal to a DC voltage, apply the DC voltage to the surgical instrument component, and deliver the second energy modality to the end effector according to the second drive signal. Alternatively, the circuit can be disposed within a cable assembly configured to connect the surgical instrument to the surgical energy module.

An end effector assembly for use with a surgical instrument is disclosed. The end effector assembly comprises a staple cartridge jaw, a threaded rod, and a replaceable staple cartridge configured to be seated in the staple cartridge jaw. The replaceable staple cartridge comprises a proximal end, a distal end, a longitudinal slot extending between the proximal end and the distal end, and a driver configured to support a staple, wherein the driver comprises a surface facing the threaded rod, wherein the surface comprises a clearance, and wherein at least a portion of the threaded rod is configured to be received in the clearance when the replaceable staple cartridge is seated in the staple cartridge jaw.

A surgical stapling device includes a drive assembly and a knife bar assembly that can be selectively coupled together or uncoupled from each other to place the stapling device in a cutting mode or in a non-cutting mode. The stapling device may also include a locking member that locks a distal portion of the anvil to a distal portion of the cartridge assembly to define a maximum tissue gap between the anvil and the cartridge assembly.

A surgical stapling instrument includes a releasable stapling end effector. The stapling end effector includes a body portion, a jaw assembly pivotally secured to the body portion, and an articulation mechanism extending between the body portion and the jaw assembly. The jaw assembly is articulable between a non-articulated position and at least one articulated position. The articulation mechanism includes a barrel member and first and second linkage assemblies. The barrel member defines a channel and each of the first and second linkage assemblies include a protrusion received within the channel. Rotation of the barrel member in a first direction causes the first linkage assembly to move in a proximal direction and the second linkage assembly to move in a distal direction to cause the jaw assembly to move from the non-articulated position to the at least one articulated position.

A stapling device includes an adapter assembly and a reload assembly that includes a reload release mechanism that is movable from a locked position in which the reload assembly is locked onto the adapter assembly to an unlocked position in which the reload assembly can be removed from the adapter assembly. The adapter assembly of the stapling device includes a lockout that prevents movement of the reload release mechanism to the unlocked position unless the stapling device is in a non-articulated, unfired position.

An apparatus includes a body and a shaft assembly. The body includes a rotary drive output, a linear drive output, and a control module. The shaft assembly includes a distal end and a proximal end. The distal end includes a type of end effector configured to operate on tissue. The proximal end is configured to removably couple with the body assembly. The proximal end includes one or both of a rotary drive input configured to couple with the rotary drive output or a linear drive input configured to couple with the linear drive input. The shaft assembly is configured to actuate the end effector in response to movement of one or both of the rotary drive input or the linear drive input. The control module is configured to selectively actuate the rotary drive output or the linear drive output based on the type of end effector of the shaft assembly.
