A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

Surgical Stapling Apparatus

A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of the cartridge (10) and the anvil (22). The cartridge (10) can be moved towards the anvil (22) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge (10) and is positioned such that there is at least one row of staples on at least one side of the knife.

A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Surgical stapling instrument with an articulatable end effector

A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

A piece of buttress material and an end-effector of a surgical instrument including features which can aid a surgeon in properly and quickly attaching the piece of buttress material to the end-effector. In various embodiments, a piece of buttress material can include retention features which can be engaged with portions of an end-effector to releasably retain the piece of buttress material to at least a portion of the end-effector. Similarly, an end-effector can include features configured to engage portions of a piece of buttress material to releasably retain the piece of buttress material to the end-effector. In at least one embodiment, more than one piece of buttress material can be releasably retained to an end-effector.

Surgical end effector having buttress retention features

A surgical instrument including a drive mechanism configured to advance a staple driver and/or cutting member at a first rate and retract the staple driver and/or cutting member at a different rate. In at least one embodiment, the rate at which the driver and cutting member is advanced and/or retracted is the distance that the driver and/or cutting member is translated per actuation of a trigger, for example. In various embodiments, the cutting member can be retracted at a faster rate as compared to the rate in which it is advanced. In such embodiments, the surgical instrument can, owing to the slower advancing rate, provide a greater torque or advancing force to the cutting member while, owing to the faster retracting rate, reduce the time required for the surgeon to retract the cutting member.

Surgical Instrument Having A Multiple Rate Directional Switching Mechanism

A self contained motor-powered disposable loading unit for use with a surgical cutting and stapling apparatus. The disposable loading unit may contain a battery that is retained in a disconnected position when the disposable loading unit is not in use and is moved to a connected position when the disposable loading unit is coupled to the surgical cutting and stapling apparatus to permit the motor to be selectively powered thereby. Indicators may be supported on the disposable loading unit to indicate when the axial drive assembly thereof is in a starting position and an ending position. Another indicator may be provided to indicate when the anvil assembly is in a closed position.

Disposable motor-driven loading unit for use with a surgical cutting and stapling apparatus

A surgical instrument is disclosed. According to various embodiments, the instrument includes a handle assembly and a drive system that is at least partially supported by the handle assembly. A surgical implement may be operably coupled to the handle assembly for receiving at least two independent drive motions from the drive system to cause the surgical implement to perform at least two surgical activities. The instrument may further include a timing indicator on at east one of the handle assembly and the surgical implement to provide an indication of an amount of time that has elapsed from an application of one of the control motions while maintaining an ability to selectively apply a second control motion after the first control motion has been applied.

Surgical instrument with apparatus for measuring elapsed time between actions

A piece of buttress material (B) and an end-effector (14) of a surgical instrument including features which can aid a surgeon in properly and quickly attaching the piece of buttress material (B) to the end-effector (14). In various embodiments, a piece of buttress material (B) can include retention features (262) which can be engaged with portions of an end-effector (14) to releasably retain the piece of buttress material (B) to at least a portion of the end-effector (14). Similarly, an end-effector (14) can include features configured to engage portions of a piece of buttress material (B) to releasably retain the piece of buttress material (B) to the end-effector (14). In at least one embodiment, more than one piece of buttress material (B) can be releasably retained to an end-effector (B).
