The technology relates to a surgical system with an end effector. 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

An electromechanical surgical device includes an end effector configured to perform at least one function, the end effector including an input drive axle projecting therefrom; and a shaft assembly. The shaft assembly includes a rotatable drive shaft; a proximal neck housing supported at a distal end of an outer tube; a distal neck housing pivotally connected to the proximal neck housing; a pivot pin interconnecting the proximal neck housing and the distal neck housing; and a gear train supported in the proximal neck housing, on the pivot pin, and in the distal neck housing. The gear train includes a proximal gear; an intermediate gear; a distal gear; and a pair of output gears, wherein each output gear defines a coupling socket each configured to selectively receive the drive axle of the end effector.

An end effector includes an upper jaw, a lower jaw, and a staple cartridge assembly that is received within the lower jaw. The staple cartridge assembly includes an actuation sled and a knife sled. A drive beam is received within the lower jaw and is movable between a retracted beam position and an advanced beam position to move the actuation sled and the knife sled from retracted positions to advanced positions. The end effector includes a locking clip to releasably couple the drive beam to the knife sled.

An electromechanical surgical system having an instrument housing for connecting with a shaft assembly, a shaft assembly, and an end effector. 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 surgical device is disclosed. The surgical device includes: a jaw assembly including a first jaw and a second jaw moveable relative to the first jaw; and an articulating assembly removably coupled to the proximal end of the jaw assembly, the articulating including a distal joint member, a proximal joint member, and a pivot pin fixedly coupled to the distal joint member and rotatably coupled to the proximal joint member, wherein the jaw assembly and the distal joint member define a first longitudinal axis extending between a proximal end of the jaw assembly and a distal end of the distal joint member, and the proximal joint member defines a second longitudinal axis. The surgical device also includes a first rotatable drive shaft including a first gear element meshingly engaged with a pivoting gear element fixedly coupled to the pivot pin, wherein rotational and longitudinal movement of the first rotatable drive shaft pivots the jaw assembly relative to the proximal joint member about a pivot axis defined by the pivot pin that is perpendicular to the first and second longitudinal axes.

An end effector for use with a surgical apparatus. The end effector comprising a staple cartridge having a tissue contacting surface defining a central longitudinal slot and an anvil plate having a tissue contacting surface defining a central longitudinal slot. A folded surgical buttress configured to overlie each of the tissue contacting surfaces of the staple cartridge and anvil plate and configured to retain the surgical buttress to the tissue contacting surfaces of each of the staple cartridge and anvil plate. The surgical buttress having a first longitudinal portion, a second longitudinal portion, and middle longitudinal portion between the first and second longitudinal portions, wherein the middle longitudinal portion is folded and configured to fit within the central longitudinal slot of each of the staple cartridge and anvil plate.

Folded buttress for use with a surgical apparatus

A surgical stapling device has an elongated body and a removable loading unit and a securing structure for securing the loading unit onto the elongated body. A guiding ramp guides the movement of the loading unit as it is mounted onto the loading portion. The locking structure has a first position for locking movement of the loading unit and enabling firing rod to engage the loading unit. The locking unit has a second position for allowing the loading unit to be disengaged and removed from the device.

Surgical instrument with replaceable loading unit

A surgical stapler includes a tubular body portion and a cartridge assembly disposed at a distal end of the body portion for expelling an annular array of staples. Each of the staples of the annular array of staples has a generally bent backspan. An anvil member disposed at the distal end of the tubular body portion is positioned opposite the cartridge assembly to clinch the staples in tissue upon expulsion of the staples from the cartridge assembly. The anvil member has a corresponding annular array of staple forming buckets. Each of the buckets is configured to accommodate the generally bent configuration of the staples to facilitate formation thereof.

Surgical fastener applying apparatus

A surgical device includes a jaw assembly, an articulating assembly and a drive shaft. The jaw assembly includes first and second jaws. The articulating assembly is removably coupled to a proximal end of the jaw assembly and includes a distal joint member, a proximal joint member, and a pivot pin. The pivot pin is fixedly coupled to the distal joint member and is rotatably coupled to the proximal joint member. The jaw assembly and the distal joint member together define a first longitudinal axis. The proximal joint member defines a second longitudinal axis. The drive shaft includes a gear element that is meshingly engaged with a pivoting gear element that is fixedly coupled to the pivot pin. Longitudinal movement of the first drive shaft pivots the jaw assembly relative to the proximal joint member about a pivot axis defined by the pivot pin.

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.

A surgical instrument includes a first jaw defining a channel, a second jaw including an anvil plate, a staple cartridge, and a drive beam. The staple cartridge is received in the channel and includes a sled, a knife blade, a plurality of staple pushers, and a plurality of staples.
