The end effector may include a drive beam, an anvil assembly, and a cartridge assembly movable in relation to the anvil assembly between an open position and a clamped position. The cartridge assembly includes a cartridge body, staples supported within the cartridge body, and an actuation sled assembly. The actuation sled assembly includes an actuation sled and a knife blade supported on the actuation sled for movement between a concealed position and a raised position. The actuation sled assembly is movable within the cartridge body in response to movement of the drive beam from the beam retracted position to the beam advanced position, from a sled retracted position to a sled advanced position to eject the staples from the cartridge body.

Apparatus for endoscopic procedures

A surgical stapling apparatus (stapler) including a housing, elongated member, and a reload is disclosed. A cartridge is configured to selectively couple to a first jaw member of the reload and includes one or more resilient members thereon. An anvil operably supported on a second jaw member of the reload is configured to compress one or more fasteners ejected from the cartridge. The anvil includes one or more locking members thereon. A knife is configured to translate through the cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the knife and the resilient member(s) causes the resilient member(s) to move from an initial configuration that allows the knife to travel distally past the locking member(s) to a final configuration that allows the locking member(s) to engage the knife.

The end effector is an articulating end effector and the system includes a cable tensioning system for tensioning the articulation cables. The system includes a clutch mechanism for preventing slippage of a drive cable. The electromechanical system includes a staple cartridge that includes a knife that is movable between a raised position and a lowered position.

A cartridge assembly includes a channel and a removable assembly in releasable engagement with the channel. The removable assembly includes a cartridge body and a support plate. The cartridge body includes an engagement structure disposed adjacent a proximal end thereof. The support plate is configured to mechanically engage the cartridge body and includes an engagement structure disposed adjacent a proximal end thereof. The engagement structure of the cartridge body is configured for longitudinal alignment with the engagement structure of the support plate. The engagement structures of the cartridge body and the engagement structure of the support plate are configured to mechanically engage the engagement structure of the channel when the removable assembly is engaged with the channel.

Multi-use loading unit

A loading unit including double pushers and double retention cavities is disclosed. At least one double pusher includes a first body portion having a first upper surface configured to engage a portion of a first fastener, a second body portion having a second upper surface configured to engage a portion of a second fastener, and a bridge interconnecting the first body portion and the second body portion. Each of the first upper surface and the second upper surface defining an acute angle with respect to a longitudinal axis. At least one double retention cavity includes a first retention guiding surface configured to engage a proximal pusher guiding surface of the first body portion of the double pusher retained therein, and a second retention guiding surface configured to engage a distal pusher guiding surface of the first body portion of the double pusher retained therein.

Loading unit for surgical instruments with low profile pushers

A surgical stapling device includes an elongate member and a loading unit. The loading unit includes a tool portion and a body portion including a first portion having a first length, a second portion having a second length, and a third portion having a third length. The first portion is configured to be releasably secured with the elongate member. The second portion is distal of the first portion and dimensioned to be received in the elongate member. The third portion is distal of the second portion. At least the second or third portion is configured to engage the elongate member in a sealing relation. The second length is greater than the first and third lengths. The third portion of the body portion is dimensioned to be flush with the elongate member when the first and second portions are received in the elongate member.

Surgical stapling device

A loading unit for engagement with a surgical instrument, and including single and double retention slots, is discloses. At least one single retention cavity includes a first retention guiding surface configured to engage a first pusher guiding surface of a single pusher retained therein, a second retention guiding surface configured to engage a second pusher guiding surface of a single pusher retained therein, a third retention guiding surface configured to engage a third pusher guiding surface of a single pusher retained therein, and a fourth retention guiding surface configured to engage a fourth pusher guiding surface a the single pusher retained therein. At least one double retention cavity includes a first retention guiding surface configured to engage a first pusher guiding surface of a double pusher retained therein, and a second retention guiding surface configured to engage a second pusher guiding surface of a double pusher retained therein.

A cartridge assembly includes a cartridge channel, a support plate, a staple cartridge supported within the support plate and the cartridge channel, and compression members.
