Abstract: Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridge for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch for maintaining the locking member in the disabled position. The switch may be further configured to operate as a reload detection mechanism for determining the type of reload present in the surgical stapling instrument.

Abstract: Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridges for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch movable in a lateral direction to either maintain the locking member in the disabled position or to allow the locking member to move into the locking position. The instrument may further include a stapler cartridge including an annular pin configured to be engaged by a drive member at a an axial position to create a detectable resistance for reload detection by a control unit to identify the type of stapler cartridge present in the surgical stapling instrument.

Abstract: The present disclosure provides a staple cartridge for a surgical instrument, such as a tissue sealing instrument. The staple cartridge includes a housing and one or more staple assemblies within the housing. The staple assemblies each include one or more staple pushers and associated staples. The staple pushers and housing include coupling elements configured to cooperate with each other to retain the staple assemblies to the housing prior to use in surgery. The coupling elements, along with other components of the cartridge and instrument, result in a smaller staple cartridge relative to conventional devices, allowing for a more compact and maneuverable surgical instrument.

Abstract: The present disclosure provides a surgical instrument, such as a tissue sealing instrument, with an elongate shaft and an end effector. The end effector includes a first jaw and a second jaw that includes a staple cartridge with a plurality of staples for engaging tissue. The instrument further includes a drive member for closing the jaws and engaging the staples, and an actuation mechanism, such as a coil, in contact with the drive member. The actuation mechanism is configured to translate the drive member distally through the first jaw (instead of through the staple cartridge as in conventional surgical stapling instruments). Eliminating the internal channel for the actuation coil from the staple cartridge provides more space in the cartridge for the staples, allowing for the use of taller staples and/or a more compact and maneuverable instrument.

Abstract: A stapler reload assembly includes a cartridge body defining a housing to receive staples. The cartridge body has a first side comprising a plurality of staple apertures configured to eject staples housed in the cartridge body. The cartridge body has a second side, opposite the first side, comprising a plurality of pusher apertures through which staple pushers of the cartridge body are accessible. A staple retainer is removably coupled to the first side of the cartridge body and at least partially covers the plurality of staple apertures. A cover is removably coupled to and at least partially covers the plurality of pusher apertures. Devices and methods relate to stapler reload assemblies.
