Abstract: Surgical instruments, such as clamping and cutting instruments, are provided. In one aspect, a surgical stapling instrument comprises first and second jaws and a drive member configured to move in a distal direction through at least one of the jaws. The instrument further includes a locking member movable between a first position permitting distal translation of the drive member, and a second position impeding distal translation of the drive member, and a switch movable from a proximal position to a distal position. When the switch is in the proximal position, it releasably maintains the locking member in the first position, and when the switch is in the distal position, it allows the locking member to move to the second position. This inhibits or prevents actuation of a knife when there is a spent or previously fired cartridge loaded in the 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: Locking assemblies for surgical clamping and cutting instruments include a locking member and a switch. A drive member may be configured to releasably engage a knife and/or a shuttle of the surgical instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member is movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. A switch, when proximally positioned, releasably engages the locking member to maintain the locking member in the first position. The switch disengages from the locking member when the switch is moved to a distal position.

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.
