A modular energy system including a header module configured to removably connect to an energy module. The energy module can comprise a port configured to deliver one or more energy modalities to a surgical instrument connected thereto. The header module can comprise a display screen configured to display a user interface. The header module can further include a control circuit configured to detect attachment of energy modules to the modular energy system and control the display of the user interface to display UI portions for each connected module and reconfigure the displayed UI portions to accommodate the new UI portions as additional energy modules are connected to the modular energy system.

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 surgical end effector includes a cartridge. The cartridge includes first and second sensor arrays disposed in the cartridge. The first sensor array is configured to sense a function of a first component located within the cartridge and the second sensor array is configured to sense a function of a second component located within the cartridge. The first and second sensor arrays are electrically coupled to an electronic circuit. The electronic circuit includes a control circuit configured to receive signal samples from the first sensor array, receive signal samples from the second sensor array, and process the signals samples received from the first and second sensor arrays to determine a status of the cartridge.

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.

A method for controlling a powered surgical stapler that includes an end effector with jaws that are movable between an open and a closed position and a firing member that is movable between a starting position and an ending position within the end effector. The jaws and firing member are controlled by separate rotary systems and the end effector includes a firing member lockout system that prevents axial movement of the firing member unless the surgical staple cartridge is in ready to fire condition.

A method of applying a buttress to a surgically cut and stapled site uses an end effector with a buttress applier cartridge assembly to load one or more buttress assemblies to the end effector. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The adhesive of the buttress assemblies can include a pattern to assist in both attachment to the end effector and release from the end effector after cutting and stapling a tissue site. The buttress applier cartridge can include features that accommodate end effectors having various tip configurations, including straight tips and curved or bent tips.

A surgical instrument is disclosed. The surgical instrument can include a first jaw, a second jaw, and a jaw closure lockout system. The first jaw can comprise a pivot pin slot and a slide pin slot. The second jaw can comprise an anvil and, in addition, a mounting portion comprising a pivot pin, which can be movably positioned in the pivot pin slot. A shiftable guide can be movably positioned in the first jaw and can comprise a body and a barrier wall. The body can comprise a slide pin movably positioned in the slide pin slot. The barrier wall can be aligned with a portion of the pivot pin slot when the slide pin is positioned within a range of positions in the slide pin slot, and the barrier wall can be offset from the pivot pin slot when the slide pin is positioned outside the range of positions.
