  • BACKGROUND
  • 1. Technical Field
  • The present disclosure relates to a surgical stapling apparatus and, more particularly, to a surgical stapling apparatus including a detachable surgical buttress for an anvil and a staple cartridge.
  • 2. Background of Related Art
  • Surgical stapling instruments that are used to sequentially or simultaneously apply one or more rows of fasteners to join segments of body tissues are well known in the art. The fasteners are typically in the form of surgical staples but two part polymeric fasteners can also be utilized. Such devices generally include a pair of jaws to clamp therebetween the body tissues to be joined. Typically, one of the jaw members includes a staple cartridge which accommodates a plurality of staples arranged in at least two lateral rows while the other jaw member has an anvil that defines a surface for forming the staple legs as the staples are driven from the staple cartridge.
  • When the stapling instrument is actuated, longitudinally translating cams contact staple drive members in one of the jaws which in turn acts upon staple pushers to sequentially or simultaneously eject the staples from the staple cartridge. A blade can travel between the staple rows to longitudinally cut and/or open the stapled tissue between the rows of staples. Such instruments are disclosed, for example, in U.S. Pat. No. 3,079,606 and U.S. Pat. No. 3,490,675.
  • When stapling relatively thin or fragile tissues, it is important to effectively seal the staple line against air or fluid leakage. Additionally, it is often necessary to reinforce the staple line against the tissue to prevent tears in the tissue or pulling of the staples through the tissue. One method of preventing tears or pull through involves the placement of a biocompatible fabric reinforcing material, or a “buttress,” between the staple and the underlying tissue. In this method, a layer of buttress material is placed against the tissue and the tissue is stapled in conventional manner. In more recent methods, the layer of buttress is positioned on the stapling instrument itself prior to stapling the tissue. Some surgical staplers utilize fasteners or clips to temporarily connect buttress material to each of the jaws of the staplers, i.e., one disposed on the staple cartridge assembly and the other on the anvil assembly.
  • WO 2008/109125 discloses a surgical stapling apparatus that includes a cartridge assembly, an anvil assembly, and a surgical buttress releasebly secured by an anchor. The anchor releases the surgical buttress during firing of the stapling apparatus.
  • It is a desire of the present application to provide surgical stapling apparatus with a surgical buttress secured thereto in a manner that minimizes shifting of the surgical buttress, and tearing or other damage to the surgical buttress during assembly. It would also be desirable to provide a single profile buttress that can be used on a surgical staple cartridge assembly and/or a surgical anvil cartridge assembly, as well as cartridge and anvil assemblies of different sizes. Accordingly, it is an object of this disclosure to meet the aforementioned desires.

  • DETAILED DESCRIPTION OF EMBODIMENTS
  • Embodiments of the presently disclosed staple line reinforcement for anvil and cartridge of a loading unit of a surgical stapling apparatus will now be described in detail with reference to the drawings, in which like reference numerals designate identical or corresponding elements in each of the several views. In the drawings and in the description that follows, the term “proximal,” as is traditional, will refer to the end of the stapling apparatus which is closest to the operator, while the term “distal” will refer to the end of the apparatus which is farthest from the operator.
  • Referring now to FIG. 1, there is disclosed a linear surgical stapling apparatus, generally referred to as 10. In the interest of brevity, this disclosure will focus primarily on a buttress utilized in a loading unit 100, e.g., a single use loading unit (“SULU”) or a disposable loading unit (“DLU”). For simplicity, hereinafter, SULU or DLU will be referred to as “DLU,” but it should be understood to include either or both a DLU or SULU. An exemplary example of this type of surgical stapling instrument is disclosed in U.S. Pat. No. 7,128,253, the entire disclosure of which is hereby incorporated by reference herein.
  • Surgical stapling apparatus 10 generally includes a handle assembly 12 and an elongate body 14 extending distally from handle assembly 12. A DLU 100 is releasably secured to the distal end of elongate body 14. DLU 100 includes a cartridge assembly 200 housing a plurality of surgical fasteners or staples 223 (see FIG. 2) and an anvil assembly 300 movably secured in relation to cartridge assembly 200. Handle assembly 12 includes a stationary handle member 22, a movable handle member 24, and a barrel portion 26. An articulation lever 30 is mounted on the forward end of barrel portion 26 adjacent rotatable member 28 to facilitate articulation of DLU 100. A pair of knobs 32 is movably positioned along barrel portion 26. Knobs 32 are advanced distally to approximate or close cartridge and/or anvil assembly 200, 300, and retracted proximally to unapproximate or open cartridge and/or anvil assembly 200, 300. Actuation of movable handle member 24 applies lines of staples 223 to tissue. In order to properly orient cartridge and anvil assembly 200, 300 relative to the tissue to be stapled, surgical stapling apparatus 10 is additionally provided with a rotatable member 28 on the forward end of barrel portion 26.

  • Reference may be made to U.S. patent application Ser. No. 12/342,400, filed on Dec. 23, 2008 (U.S. Pat. No. 8,011,555), the entire content of which is hereby incorporated herein by reference, for a detailed discussion of the construction and operation of surgical stapling apparatus 10, cartridge assembly 200 and/or anvil assembly 300.
  • It is contemplated that the cartridge buttress and/or anvil buttress can be attached by other means. For example, in any of the embodiments disclosed herein, the buttresses can be attached using adhesives, welding, and/or attachment features incorporated in the buttress material.
  • Buttress 500 for each of cartridge assembly 200 and anvil assembly 300 is provided to reinforce and seal staple lines applied to tissue by surgical stapling apparatus 10. Cartridge assembly 200 and anvil assembly 300 are particularly configured to allow surgical buttresses 500 to be localized on inwardly facing surfaces of cartridge assembly 200 and anvil assembly 300 in order to facilitate passage of surgical stapling apparatus 10 into the body of a patient without risk of tearing or wrinkling of the respective buttresses as surgical stapling apparatus 10 is inserted into and manipulated within the body of a patient. The material from which the buttress 500 is formed may be bioabsorbable or non-bioabsorbable. It should be understood that any combination of natural, synthetic, bioabsorbable and non-bioabsorbable materials may be used to form the buttress material. The buttress material may be porous or non-porous, or a combination of porous and non-porous layers. The non-porous buttress material may be utilized to retard or prevent tissue ingrowth from surrounding tissues thereby acting as an adhesion barrier and preventing the formation of unwanted scar tissue.
  • Additional exemplary materials for surgical buttresses 500 for use with the surgical stapling devices disclosed herein are set forth in commonly assigned U.S. Pat. Nos. 5,542,594; 5,908,427; 5,964,774; and 6,045,560, and commonly assigned U.S. Application Publication Nos. 2006/0085034, filed on Apr. 20, 2006; and 2006/0135992, filed on Jun. 22, 2006, the entire contents of each of which is hereby incorporated herein by reference.
  • In an embodiment, surgical buttresses 500 may be fabricated from a suitable biocompatible and bioabsorbable material. Surgical buttresses 500 may also be fabricated from a non-absorbent material which does not retain fluid, for example, surgical buttresses 500 may be fabricated from “BIOSYN™” (a synthetic polyester, commercially available from Tyco Healthcare Group, LP d/b/a COVIDIEN, North Haven, Conn.), which is made from “GLYCOMER 631” (a block copolymer) which is a synthetic polyester composed of glycolide, dioxanone and trimethylene carbonate.
  • One block of the resulting copolymer contains randomly combined units derived from p-dioxanone (1,4-dioxan-2-one) and trimethylene carbonate (1,3-dioxan-2-one). A second block of the copolymer contains randomly combined units derived from glycolide and p-dioxanone. The resulting polyester is an ABA triblock terpolymer possessing about 60% glycolide, about 14% dioxanone, and about 26% trimethylene carbonate.
  • Anvil buttress and/or cartridge buttress 500 may be pre-loaded (i.e., from the manufacturer) onto anvil assembly 300 or cartridge assembly 200. Additional or replacement buttresses 500 for anvil assembly 300 and/or cartridge assembly 200 may be secured to either anvil assembly 300 or cartridge assembly 200 as needed or desired.
  • In operation, with DLU 100 coupled to a distal end of elongated body 14 of surgical stapling apparatus 10, and with anvil and cartridge buttresses 500 pre-loaded onto anvil assembly 300 and cartridge assembly 200, respectively, surgical stapling apparatus 10 is used in accordance with methods known by those skilled in the art. Once anvil assembly 300 and cartridge assembly 200 are clamped onto tissue, surgical stapling apparatus 10 is fired. In firing surgical stapling apparatus 10, drive bar 150 is advanced from a proximal-most position to a distal-most position of DLU 100. In so doing, knife blade 156 of drive bar 150 enters notch 528 of buttress 500 thereby facilitating the dividing of buttress 500 and reducing any incidents of pushing or bunching-up of buttress 500 by blade 156. As drive bar 150 begins to travel distally, knife blade 156 substantially simultaneously cuts through a central section of the proximal anchors “S2, S4” of anvil assembly 300 and cartridge assembly 200, thereby respectively freeing the proximal ends of anvil and cartridge buttresses 500 therefrom. As knife blade 156 is moved distally, knife blade 156 slices or cuts longitudinally through both anvil buttress 500 and cartridge buttress 500, thereby dividing the buttresses 500 substantially in half.
  • Additionally, as drive bar 150 approaches the distal-most position, drive bar 150 and/or knife blade 156 engage a suture cutting assembly or suture release assembly, as described in U.S. patent application Ser. No. 12/342,400, filed on Dec. 23, 2008, the entire content of which is hereby incorporated herein by reference, to thereby sever or release distal sutures “S1 or S3” and thus release a distal end of buttress 500.
  • With reference to FIG. 3, an embodiment of a surgical buttress 500 having a uniform profile in accordance with the present disclosure is illustrated. Buttress 500 includes a head portion 510, a body portion 520, a neck portion 530 interconnecting head portion 510 and body portion 520, and a tail portion 532 extending proximally from body portion 520.
  • Buttress 500 is configured to be detachably secured to any sized anvil assembly 300 and/or cartridge assembly 200, as described above. Body portion 520 of buttress 500 defines a pair of opposing distal recesses 524 on transverse edges near a distal location 522 thereof. The pair of opposing distal recesses 524 may be utilized to secure body portion 520 to a distal end of anvil assembly 300 and/or cartridge assembly 200, either through a use of suture “S1 or S3” or any other type of fastener, e.g., staple. Distal portion 522 of body portion 520 has a reduced transverse cross-sectional dimension, e.g., angled, arcuate, so as to be suitable for various types of anvil and cartridge assemblies having different shapes.
  • Tail portion 532 of buttress 500 defines two pairs of opposing proximal recesses 526 a, 526 b formed therein. Each of the pair of proximal recesses 526 a, 526 b is disposed on a transverse side of tail portion 532 near the proximal edge thereof. Such proximal pair of recesses 526 a, 526 b serve to detachably secure tail portion 532 of buttress 500 to a proximal end of anvil assembly 300 and/or cartridge assembly 200. In order to accommodate various types of profiles, tail portion 532 of buttress 500 preferably has been provided with two pairs of opposing recesses, a first proximal pair of recesses 526 a, and a second proximal pair of recesses 526 b (located distal of the first proximal pair of recesses 526 a). Each of the proximal pair of recesses 526 a, 526 b has a substantially v-shape profile.
  • In particular, when buttress 500 is to be used with a relatively longer anvil assembly 300 and/or cartridge assembly 200, then a suture “S2 or S4” is extended across tail portion 532 of buttress 500, passed through the proximal-most pair of recesses 526 a of buttress 500, and secured to respective recesses 316 of anvil assembly 300 and/or recesses 236 of cartridge assembly 200. Moreover, when buttress 500 is to be used with a relatively shorter anvil assembly 300 and/or cartridge assembly 200, then a suture “S2 or S4” is extended across tail portion 532 of buttress 500, passed through the distal pair 526 b of the proximal pair of recesses of buttress 500, and secured to respective recess 316 of anvil assembly 300 and/or recesses 236 of cartridge assembly 200.
  • According to another aspect of the present disclosure, a single profile or configuration buttress 500 may be used in connection with cartridge assembly 200 and/or anvil assembly 300. For example, the buttresses 500 that are used in connection with cartridge assembly 200 and anvil assembly 300 each may have the same overall length, width, thickness, perimetrical profile and material of construction.
  • In particular, as seen in FIG. 10, when buttress 500 is used in connection with cartridge assembly 200, a suture “S1” may extend transversely across a distal end portion of cartridge assembly 200 and captures or is otherwise secured to distal pair of recesses or attachment points 238 of cartridge assembly 200, wherein suture “S1” is in registration with distal recesses 524 of secure a distal end of body portion 520 of buttress 500. Additionally, when buttress 500 is used in connection with cartridge assembly 200, a suture “S2” may extend transversely across a proximal end portion of cartridge assembly 200 and captures or is otherwise secured to each of a proximal pair of recesses or attachment points 236 of cartridge assembly 200, wherein suture “S2” is in registration with the proximal-most pair 526 a of the proximal pair of recesses of tail portion 532 of buttress 500.
  • With continued reference to FIG. 10, when buttress 500 is used in connection with anvil assembly 300, a suture “S3” may extend transversely across a distal end portion of anvil assembly 300 and captures or is otherwise secured to distal pair of recesses or attachment points 318 of anvil assembly 300, wherein suture “S3” is in registration with distal recesses 524 of secure a distal end of body portion 520 of buttress 500. Additionally, when buttress 500 is used in connection with anvil assembly 300, a suture “S4” may extend transversely across a proximal end portion of anvil assembly 300 and captures or is otherwise secured to each of a proximal pair of recesses or attachment points 316 of anvil assembly 300, wherein suture “S4” is in registration with the distal pair 526 b of the proximal pair of recesses of tail portion 532 of buttress 500.
  • Neck portion 530 connects head portion 510 to a distal end of body portion 520. Generally, head portion 510 is in a substantially rectangular shape which is used as a tab to facilitate placement of buttress 500 in position on anvil assembly 300 and/or cartridge assembly 200. Following placement of buttress 500 on anvil assembly 300 and/or cartridge assembly 200, head portion 510 and neck portion 530 may be torn or otherwise cut away from body portion 520.
  • Tail portion 532 of buttress 500 includes a notch 528 at a proximal edge thereof. Notch 528 is substantially centered with respect to the longitudinal axis. Notch 528 which has a triangular or V-shape configuration may be utilized to provide a lead-in for the knife during a cutting of buttress 500. Notch 528 has a length “L3 a”, as seen in FIG. 3.
  • As seen in FIG. 3, buttress 500 has an overall length “La”. Body portion 520 of buttress 500 has a length “L1 a”, and tail portion 532 has a length “L2 a”. Body portion 520 has a width “W1 a” and tail portion 532 has a width “W2 a” which is less that width “W1 a” of body portion 520, wherein a shoulder 534 is defined between a side edge of body portion 520 and a side edge of tail portion 532. It is contemplated that a shoulder 534 is provided or defined along each opposed side edge of buttress 500.
  • With continued reference to FIG. 3, neck portion 530 of buttress 500 has a length “L4 a”, and head portion 510 has a length “L5 a”. Neck portion 530 of buttress 500 has a width “W3 a” which is less that width “W1 a” of body portion 520 and less than width “W2 a” of tail portion 532. Also, head portion 510 has a width “W4 a” which is substantially equal to width “W1 a” of body portion 520.
  • The uniform profile of buttress 500 which simultaneously satisfies the requirements of one or more different assemblies offers advantages of simplifying the assembly process, minimizing the total number of unique components, and reducing assembly costs associated therewith.
  • Moreover, buttress 500 may be used on or in connection with cartridge assembly 200 and/or anvil assembly 300. In this manner, a single profile buttress 500 is produced and used for cartridge assembly 200 and/or anvil assembly 300. As such, the manufacturing and storage costs for buttresses 500 may be reduced.
  • As mentioned above, DLU 100 includes an anvil surgical buttress 500 and a cartridge surgical buttress 500 pre-loaded onto anvil assembly 300 and cartridge assembly 200. An exemplary method of loading anvil assembly 300 and/or cartridge assembly 200 with a buttress 500 will now be described.
  • During the manufacturing and/or assembly process of DLU 100, loading of anvil assembly 300 and/or cartridge assembly 200 with buttress 500 includes the step of placing a buttress 500 atop a tissue contacting surface of anvil assembly 300 and/or cartridge assembly 200 such that notch 528 of buttress is disposed near a proximal end of anvil assembly 300 and/or cartridge assembly 200 and head portion 510 of buttress 500 extends from a distal end of anvil assembly 300 and/or cartridge assembly 200. With buttress 500 so positioned against anvil assembly 300 and/or cartridge assembly 200, proximal sutures “S2” and/or “S4” are pulled down. Tension is then applied to buttress 500, in a distal direction, by pulling on head portion 510. Distal sutures “Sl” and/or “S3” are then pulled down. At this time, all the sutures “S1-S4” are cinched in the respective attachment points 316, 318, 236, 238 of anvil assembly 300 and/or cartridge assembly 200. Following cinching of sutures “S1-S4,” head portion 510 of buttress 500 may be released. Next, DLU 100 may be removed from a nesting and head portion 510 and neck portion 530 of buttress 500 may be removed or severed from body portion 520.
