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.

Various forms of surgical instruments are disclosed. In various embodiments, the instrument includes a cartridge supporting assembly for operably supporting a staple cartridge therein. The cartridge supporting assembly may be responsive to firing and retraction motions applied thereto from a firing assembly. An anvil may be operably coupled to an anvil closure assembly. The anvil closure assembly may be constructed to selectively move the anvil in a proximal direction toward the cartridge supporting assembly to enable a portion of tissue to be clamped between a cartridge supported by the cartridge supporting assembly and the anvil under a predetermined amount of compression. The device may further include a compression limiting assembly that interacts with the anvil closure assembly to prevent further travel of the anvil in the proximal direction toward the cartridge supporting assembly when the predetermined amount of compression has been attained.

FIELD: medical equipment.SUBSTANCE: group of inventions relates to medical equipment, namely to surgical instruments, and, in particular, to surgical incision and suturing instruments, and used cassettes therein with staples. Cassette with staples for use with surgical stapling device comprises cartridge body, multitude of staples and implanted compressed part. Cartridge body comprises panel and multiple seats for staples, made in panel, wherein each staple seat has hole in panel. Multitude of staples, in which at least part of each staple is stored in staple seat with possibility to remove. Each staple can displace between activated and non-activated positions, wherein multitude of staples comprises first set of staples and second set of staples. Implanted compressed part passes above panel and comprises surface, contacting with tissue, when moved in activated position. Implanted compressed part comprises first and second parts. First part is made with possibility to be entrapped in each staple of first set of staples, when staples of first set of staples are moved to activated position. Second part is made with possibility to be entrapped in each staple of second set of staples, when staples from second set of staples are moved to activated position. In second version cartridge with staples for use with surgical stapling device comprises cartridge body, multitude of staples, set in-series, implanted compressed part and multiple fasteners. Said implanted part comprises multiple detachable parts. Multiple fasteners retain detachable parts on panel, at least one of cartridge body and stapling device comprises start-up element, configured to cut fastening elements, when staples are moved between non-activated position and activated position by actuator. In third version cartridge with staples for use with surgical stapling device comprises cartridge body, multitude of staples, implanted compressed part. Said implanted part is located outside cartridge body.EFFECT: use of inventions allows to provide optimal compression pressure on surrounding tissue to limit blood flow through worse contractible blood vessels.17 cl, 389 dwg

Tissue thickness compensator comprising detachable portions

A surgical stapler includes a head in which a plurality of staples are stored. The head includes a facing surface. The stapler also includes an anvil having an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including a facing surface opposed to the facing surface of the head for mating engagement therewith. The facing surface of the head is obliquely oriented relative to a longitudinal axis of the head creating an elliptical staple line when the head is brought into contact with anvil during actuation of the surgical stapler.

The device may further include a closure actuator that operably interacts with the anvil closure assembly such that as the closure actuator is moved in a first direction, the anvil closure assembly causes the anvil to move in the proximal direction to increase the compression of the tissue between the staple cartridge and the anvil. A variable load generating member may cooperate with the anvil closure assembly and the closure actuator to apply a resistive load to the closure actuator in relation to an amount of compression applied to the tissue between the anvil and the staple cartridge.
