    BACKGROUND
    [001] In some contexts, endoscopic surgical instruments may be preferred over devices for traditional open surgery, since a smaller incision can reduce recovery time and complications in the postoperative period. Consequently, some endoscopic surgical instruments may be suitable for placing a distal end actuator in a desired surgical site through the trocar cannula. These distal end actuators can trap tissue in a variety of ways to achieve a diagnostic or therapeutic effect (for example, cutter, claw, cutter, stapler, clamp applicator, access device, drug delivery device / gene therapy and device for applying energy using ultrasound, RF, laser, etc.). Endoscopic surgical instruments can comprise a rod between the end actuator and a portion of cable, which is handled by the physician. This stem can allow insertion to a desired depth and rotation around the longitudinal axis of the stem, thus facilitating the positioning of the end actuator on the patient. The positioning of an end actuator can also be facilitated by the inclusion of one or more articulated joints or features, allowing the end actuator to be selectively articulated or even offset in relation to the longitudinal axis of the stem.
    [002] Examples of endoscopic surgical instruments include surgical staplers. Some of these staplers can be operated to staple layers of fabric, cut through stapled layers of fabric and urge staples through fabric layers to firmly join separate layers of fabric near the separate ends of the fabric layers.

DETAILED DESCRIPTION
    [0024] The following description of specific examples of the invention should not be used to limit the scope of the present invention. Other examples, characteristics, aspects, modalities and advantages of the invention will become evident to those skilled in the art from the following description, which uses illustrations, one of the best contemplated ways to carry out the invention. As will be understood, the invention can have other different and obvious aspects, all without departing from the invention. Consequently, drawings and descriptions should be considered as illustrative rather than restrictive. Exemplary surgical stapler
    [0025] FIGS. 1-6 represent an exemplary surgical stapling and separation instrument (10) that is sized for insertion, in an unarticulated state as shown in FIG. 1A, through a trocar cannula conduit to a surgical site on a patient to perform a surgical procedure. Surgical stapling and the separation instrument (10) include a cable portion (20) connected to the implement portion (22), the latter also comprising a rod (23) that ends distally in an articulation mechanism (11) and an end actuator (12) distally attached. When the articulation mechanism (11) and the end actuator (12) are inserted through the canal of the trocar cannula, the articulation mechanism (11) can be articulated remotely, as shown in FIG. 1B, by controlling the joint (13). Thus, the end actuator (12) can reach behind an organ or approach a tissue at a desired angle or for other reasons. It should be understood that terms such as "proximal" and "distal" are used in the present invention with reference to the handle portion (20) of the instrument (10) handled by the physician. In this way, the end actuator (12) is distal with respect to the most proximal portion of cable (20). It will also be recognized that, for convenience and clarity, spatial terms such as "vertical" and "horizontal" are used in the present invention in connection with the drawings. However, surgical instruments can be used in many orientations and positions, and these terms are not intended to be limiting and absolute.
    [0026] The end actuator (12) of the present example includes a lower jaw (16) and an articulated anvil (18). The handle portion (20) includes a pistol grip (24), against which a closing trigger (26) is pivotally pressed by the doctor in order to cause clamping or closing of the anvil (18) against the lower jaw ( 16) of the end actuator (12). This closure of the anvil (18) is obtained by means of an external closing sleeve (32), which moves longitudinally in relation to the cable portion (20) in response to the articulated actuation of the closing trigger (26) against the handle pistol (24). A distal closing ring (33) of the closing sleeve (32) is supported indirectly by the structure (34) of the implement portion (22). In the articulation mechanism (11), a proximal closing tube (35) of the closing sleeve (32) communicates with the distal closing ring (33). The structure (34) is flexibly connected to the lower jaw (16) via the articulation mechanism (11), allowing articulation in a single plane. The frame (34) also supports, in a longitudinal and sliding way, a firing steering member (not shown), which extends through the rod (23) and transmits a firing movement from the firing trigger (28) to the firing bar. firing (14). The trigger trigger (28) is furthest from the closing trigger (26), being pressed jointly by the doctor to staple and separate the tissue clamped on the end actuator (12), as will be described in more detail below. Then, the release button (30) is released to release the tissue from the end actuator (12).
    [0027] FIGS. 2-5 represent the end actuator (12) which employs an electronic beam firing bar (14) to perform various functions. As best seen in FIGS. 3A and 3B, the firing bar (14) includes a transverse-oriented upper pin (38), a firing cap (44), a transverse-oriented middle pin (46) and a cutting edge in distal position (48). The upper pin (38) is located and is translatable inside an anvil pocket (40) of the anvil (18). The firing bar cover (44) slidably engages the lower surface of the lower jaw (16), making the firing bar (14) extend along the groove in the channel (45) (shown in FIG. 3B) that is formed along the lower jaw (16). The middle pin (46) slidably engages the top surface of the lower jaw (16), cooperating with the trigger bar cover (44). Thus, the firing bar (14) positively spaces the end actuator (12) during firing, avoiding mechanical tightening that can occur between the anvil (18) and the lower jaw (16) with a minimum amount of tissue clamped and avoiding the malformation of staples when an excessive amount of tissue is clamped.
    [0028] FIG. 2 shows the firing bar (14) positioned proximally and the anvil (18) hinged in an open position, allowing a staple cartridge (37) to be removably installed in a lower jaw groove (16). As best seen in FIGS. 4 and 5, the staple cartridge (37) of this example includes the cartridge body (70), which contains an upper platform (72), and is coupled to a lower cartridge tray (74). As best seen in FIG. 2, a vertical slot (49) is formed through part of the staple cartridge (37). As is also best seen in FIG. 2, three rows of staple openings (51) are formed through the upper platform (72) on one side of the vertical slot (49), with another set of three rows of staple openings (51) being formed through the upper platform (72) on the other side of the vertical slot (49). Returning to FIGS. 3 to 5, a wedge-shaped sliding support (41) and a plurality of clamp actuators (43) are captured between the cartridge body (70) and the tray (74), with the wedge-shaped sliding support ( 41) with location proximal to the clamp actuators (43). The wedge-shaped sliding support (41) is movable longitudinally inside the staple cartridge (37); whereas the staple actuators (43) are movable vertically inside the staple cartridge (37). The clips (47) are also positioned inside the cartridge body (70), above the corresponding clip drivers (43). In particular, each clamp (47) is propelled vertically inside the cartridge body (70) by a clamp driver (43), in order to propel the clamp (47) through an associated clamp opening (51). As best seen in FIGS. 3A and 3B and 5, the wedge-shaped sliding bracket (41) has angled cam surfaces that push the clamp actuators (43) upward as the wedge-shaped sliding bracket (41) is propelled distally through the cartridge staples (37).
    [0029] With the end actuator (12) closed, as shown in FIG. 3A, the firing bar (14) is advanced engaged with the anvil (18), through the entrance of the upper pin (38) in a longitudinal slot of the anvil (42). A drive block (80) is located at the distal end of the firing bar (14) and is configured to engage with the wedge-shaped sliding bracket (41) so that the wedge-shaped sliding bracket (41) is pushed distally by the propeller block (80) as the firing bar (14) is advanced distally through a staple cartridge (37). During this firing, the cutting edge (48) of the firing bar (14) enters the vertical slot (49) of the staple cartridge (37), separating the clamped fabric between the staple cartridge (37) and the anvil (18) . As shown in FIGS. 3A-3B, the middle pin (46) and the drive block (80) together act on the staple cartridge (37) entering the slot (49) inside the staple cartridge (37), directing the wedge-shaped sliding support (41) in ascending cam contact with the clamp actuators (43) which, in turn, impel the clamps (47) through the clamp openings (51) and in conforming contact with the clamp forming pockets (53) on the inner surface of the anvil (18). FIG. 3B represents the firing bar (14) completely translated distally after the separation and stapling of the fabric are completed.
    [0030] FIG. 6 shows the end actuator (12) driven by a single movement through the fabric (90). The cutting edge (48) cuts through the fabric (90), while the staple actuators (43) guide three alternating rows of staples (47) through the fabric (90) on each side of the cutting line produced by the cutting edge (48 ). The clamps (47) are all oriented substantially parallel to the cut line in this example, although it should be understood that the clamps (47) can be positioned in any suitable orientations. In the present example, the end actuator (12) is removed from the trocar after the first stroke is completed, the staple cartridge sent (37) is replaced with a new staple cartridge, and the end actuator (12) is again inserted through the trocar to reach the stapling site for additional cuts and stapling. This process can be repeated until the desired number of cuts and staples (47) has been applied. The anvil (18) may need to be closed to facilitate insertion and removal through the trocar; and the anvil (18) may need to be opened to facilitate replacing the staple cartridge (37).
    [0031] It should be understood that the cutting edge (48) can separate fabrics substantially at the same time as the clips (47) are pushed through the fabric during each stroke of actuation. In the present example, the cutting edge (48) closely follows the insertion of the clips (47), so that a clip (47) is pushed through the fabric just before the cutting edge (48) passes through the same region of the fabric, although it should be understood that this order can be reversed, or that the cutting edge (48) can be directly synchronized with the adjacent clips. Although FIG. 6 show the end actuator (12) being driven in two layers (92, 94) of fabric (90), it should be understood that the end actuator (12) can be driven through a single layer of fabric (90) or more than two layers (92, 94) of fabric. It should also be understood that the formation and positioning of staples (47) adjacent to the cutting line produced by the cutting edge (48) can substantially join the fabric at the cutting line, thereby reducing or preventing bleeding and / or leakage of other body fluids into the cut line. Various suitable configurations and procedures in which the instrument (10) can be used will be apparent to those skilled in the art in view of the teachings contained herein.
    [0032] It should be understood that the instrument (10) can be configured and is operable in accordance with any other teachings of US patent No. 4,805,823; US patent No. 5,415,334; US patent No. 5,465,895; US patent No. 5,597,107; US patent No. 5,632,432; US patent No. 5,673,840; US patent No. 5,704,534; US patent No. 5,814,055; US patent No. 6,978,921; US patent No. 7,000,818; US patent No. 7,143,923; US patent No. 7,303,108; US patent No. 7,367,485; US patent No. 7,380,695; US patent No. 7,380,696; US patent No. 7,404,508; US patent No. 7,434,715; and / or US patent No. 7,721,930.
    [0033] As noted above, the descriptions of each of these patents are incorporated by reference to the present invention. Additional exemplary modifications that can be made to the instrument (10) will be described in more detail below. Several suitable ways in which the teachings below can be incorporated into the instrument (10) will be apparent to those skilled in the art. Similarly, various ways in which the teachings below can be combined with various teachings of the patents cited herein will be apparent to those skilled in the art. It should also be understood that the teachings below are not limited to the instrument (10) or the devices taught in the patents cited here. The teachings below can be readily applied to several other types of instruments, including instruments that would not be classified with surgical staplers. Various other suitable devices and configurations in which the teachings below can be applied will be apparent to those skilled in the art in view of the teachings contained herein. Exemplary cartridge with film
    [0034] FIG. 7 shows another exemplary removable cartridge (101) that can be inserted into the lower jaw (16) of the end actuator (12) shown in FIG. 2. In addition to the one shown below, the cartridge (101) in this example is similar to the cartridge (37) described above. A support (100) is disposed above the top surface (102) of the upper platform (105) of the cartridge (101). The backing (100) comprises a film that provides a hemostatic agent to the tissue (90), as described below. Alternatively, the support (100) can have any other suitable properties.
    [0035] The staple pockets (107) of the cartridge (101) are similar to the staple openings (51) described above and are configured to receive a foam, paste or gel material after the cartridge (101) is disposed in the lower jaw (16). The material contained in the pockets (107) is configured to hold the clips (47) in place in the pockets (107) and / or to seal the cured biocompatible material within the cartridge body (109) (101). The pockets (107) can include various materials, such as glue, fabric and materials that would be apparent to those skilled in the art in view of the teachings of the present invention. A backing film (100) comprising a hemostatic agent is disposed on the top surface (102) to cover the gel-filled pockets (107) and is heated to hold the backing (100) and the underlying cured material in place. In some versions, only the outer edges of the holder (100) are heated to secure the holder (100) to the cartridge (101). Any suitable devices can be used to provide such heating, including, but not limited to, an anvil (for example, a custom thermoformed die on a light press, etc.). Although the support (100) is shown as arranged on the cartridge (101), the support (100) can additionally or alternatively be arranged on a subsurface of the anvil (18) which faces the cartridge (101).
    [0036] FIG. 8 shows a clamp (47) being directed in the manner described above, in the direction of the arrow (A), towards the anvil (18) through the support (100) and in the layers of fabric (90). In some versions, clamps (47) and actuators (43) can also be coated with a hemostatic agent or other auxiliary material (described below), which can act as an activating agent to react with the support (100). For example, clamps (47) and actuators (43) can be coated with one of fibrin or thrombin, while the support (100) can comprise the other between fibrin or thrombin. As the coated clamps (47) are directed in the direction of the arrow (A) through the gel-filled pockets (107) to pierce the backing (100), the clamps (47) release a tissue repair composition material from both, staples (47) and support (100), on and on the fabric (90). For example, FIG. 8 shows the gel (103) of the gel-filled pockets (107) coated on the clip (47). Additionally, when the end actuator (12) including the cartridge (101) and the support (100) is used, the firing bar (14) is fired at the fabric (90) while slicing layers of the support (100) to release a support fabric repair composition material (100) on the fabric (90). The tissue repair composition material can be released as a tissue repair composition (104) shown in FIG. 15 when the end actuator (12) includes the fabric of the (101) staple cartridge (90) with the staples (47). In addition or as an alternative, the backing material (100) can provide reinforcement to the integrity of the mechanical fastening of the layers (92, 94) of fabric (90) by the clips (47). Surgical groups (47) may comprise a material selected from iron, nickel titanium alloy, stainless steel and / or titanium. Of course, any other suitable materials can be used.
    [0037] The material for the support (100) as well as the material arranged in pockets (107) and covered in the clamps (47) can comprise, for example, auxiliary or hemostatic agents such as fibrin or thrombin that help to clot the blood and reduce the amount of bleeding at the surgical site. The hemostatic capabilities of these auxiliary compounds can also contribute to the use of these auxiliary compounds as adhesives and sealants. The agents can help to clot blood at the surgical site, which allows the tissue surrounding the blood to remain joined and can prevent leaks along the stapled tissue site, for example.
    [0038] Such auxiliary compounds or reagents may also include, but are not limited to, medical fluid or supporting components such as low platelet plasma (PPP), platelet rich plasma (PRP), starch, chitosan, alginate, fibrin, polysaccharide, cellulose, collagen, bovine collagen, gelatin-resorcinin-formalin adhesive, oxidized cellulose, mussel-based adhesive, poly (amino acid), agarose, amylose, hyaluronan, poly (hydroxy butyrate) (PHB), hyaluronic acid, poly ( vinyl pyrrolidone) (PVP), poly (vinyl alcohol) (PVA), polylactide (PLA), polyglycolate (PGA), polycaprolactone (PCL) and their copolymers, VICRYL® (Ethicon, Inc., Somerville, NJ, USA), material MONOCRYL, PANACRYL (Ethicon, Inc., Somerville, NJ, USA) and / or any other material suitable to be mixed with biological material and introduced to a wound or problem site, including combinations of materials. For example, the support (100) may comprise a material selected from the following materials: epsilon-caprolactone glycolide, bovine pericardium, polylactic acid, polyglycolic acid, polyglactin, polydioxanone, polyglycolate, whey protein, cellulose gum, starch , gelatine, silk, nylon, polypropylene, braided polyester, polybutylester, polyethylene and / or polyetheretherketones. Other suitable compounds, materials, substances, etc., which can be used in a medical fluid or support will be apparent to those skilled in the art in view of the teachings of the present invention.
    [0039] In some versions, a medical fluid can be suspended in a biocompatible vehicle to form the support material (100). Suitable vehicles may include, for example, a physiological buffer solution, a high-flow gel solution, saline, and water. In the case of gel solutions, the tissue repair composition may be in a high-flow gel form prior to release to the target site, or it may form a gel and remain in place after release to the target site. High-flow gel solutions may comprise one or more gelling materials with or without the addition of water, saline, or physiological buffer solution. Suitable gelling materials include biological and synthetic materials. Exemplifying gelling materials include proteins, polysaccharides, polynucleotides and other materials such as alginate, crosslinked alginate, poly (N-isopropyl acrylamide), poly (oxyalkylene), poly-copolymers (ethylene oxide) -poly (propylene oxide), poly (vinyl alcohol), polyacrylate or copolymers of monostearoyl glycerol / polyethylene glycol (MGSA / PEG) and combinations of any of the above.
    [0040] The support (100) can comprise a fibrous dressing, foam, matrix, mesh or other structure, according to the teachings, by way of example, publication of US patent application No. 2009/0120994, entitled "Surgical Fastening Device with Initiator Impregnation of a Matrix or Buttress to Improve Adhesive Application", published on May 14, 2009, the description of which is incorporated herein by reference. The material can comprise, for example, a biocompatible material that is a backing, a matrix that has a plurality of openings, an open cell or closed cell foam and / or a tissue dressing. The material may include porosities that induce a capillary effect absorption feature for extracting the adhesive from the material and ensure that the openings remain free of adhesive, allowing the tissue to grow through the openings after application to the fabric.
    [0041] In addition or alternatively, the support (100) can be composed of an adhesive such as, but not limited to, polymerizable and / or cross-linked materials such as cyanoacrylate adhesive. The adhesive, for example, can be a monomeric adhesive composition (including prepolymeric), a polymeric adhesive composition or any other compound that can adhere to the fabric. In embodiments, the monomer can be a 1,1-disubstituted ethylene monomer, for example, an alpha-cyanoacrylate. When crosslinked or polymerized, cyanoacrylate can change from liquid to solid. Polymerized adhesives, for example, can be formulated to be flexible to rigid and could be spongy. If desired, the adhesive may be a single or dual part adhesive and / or may contain additives such as alternative compounds. The polymerization of the adhesive can occur from, but is not limited to, exposure to moisture, heat and / or adhesion initiators such as those described in US patent publication application No. 2009/0120994, the description of which is incorporated by way of reference above. Other suitable materials and compositions that can be used to form the support (100) will be apparent to those skilled in the art in view of the teachings of the present invention. Exemplifying Applicator
    [0042] FIGS. 9-12 are associated with the use of an exemplary disposable applicator (106). FIG. 9 shows the applicator (106) being positioned on the upper platform (111) of a cartridge (113) in a version of the end actuator (115), which has components similar to the end actuator (12) described above. For example, the anvil (117) of the end actuator (115) in this example is similar to the anvil (18) of the end actuator (12). The applicator (106) includes a first end (108) with a handle (110) to assist in pushing the applicator (106) into the cartridge (113). The handle (110) also assists in removing the applicator (106) from the cartridge (113) after the applicator material (106) is applied to the anvil (117) and cartridge (113), as described below. A second end (112) of the applicator (106) includes the portion of the applicator (114) including the material for depositing on the anvil (117) and cartridge (113).
    [0043] FIGS. 11A and 11B show alternative versions of cross sections of the applicator portion (114). FIG. 11A shows a version in which the applicator portion (114A) has an H-shaped cross section including side walls (116) and central wall (118) disposed between the side walls (116) to form the upper portion (120) and the lower portion (122). The upper portion (120) includes two layers (124, 126) of material. The first layer (124) of the material can comprise a material such as fabric arranged on top of the wall (118). The fabric may comprise, for example, a woven oxidized regenerated cellulose (ORC) which forms a support protecting an auxiliary gel. Of course, any other suitable material (for example, woven or non-woven material, mesh or textile, etc.) can be used. The second layer (126) of material may comprise a type of paste or gum (for example, adhesive such as cyanoacrylate, etc.) or any other suitable material, arranged on top of the first layer (124). The lower portion (122) includes a single layer (128) of material such as hemostatic auxiliary gel or any other suitable material. Each side of the wall (118) can include any number of layers of material.
    [0044] FIG. 11B shows a version in which the applicator portion (114B) has a cross section including side walls (130) and central wall (132) disposed between side walls (130) to form the upper portion (134) and the lower portion (136). The upper portion (134) includes two arms (138) facing each other, each arm (138) extending inwardly from a respective side wall (130). The arms (138), the side walls (130) and the central wall (132) also form a T-shaped channel (140) within the upper portion (134). The arms (138) assist in retaining the material within the T-shaped channel (140), which retains two layers (142, 144) of material. The first layer (142) of material may comprise a material such as fabric arranged on top of the central wall (132). Similar to portion (114A), the fabric may comprise, for example, an ORC woven forming a backing to protect an auxiliary gel. The second layer (144) of material may comprise a type of gum or paste or any other suitable material, arranged on top of the first layer (142). The lower portion (136) includes a single layer (146) of material such as the hematomatic auxiliary gel or any other suitable material. Each side of the wall (132) can include any number of layers of material.
    [0045] In relation to FIG. 9, regardless of which applicator portion (114A, 114B) is used, the applicator (106) is routed on the cartridge (113) to apply the gel (128) on the cartridge platform (111) (113). In the application, the side walls (116, 130) of the applicator (106) are dimensioned for the sliding receipt in the direction of the arrow (B) on the side walls (148) of the cartridge (113). The applicator (106) locates and aligns easily on the cartridge (113). When the applicator portion (114A) of the applicator (106) is completely received on the cartridge platform (111), a user can direct the anvil (117) towards the cartridge (113) as described above. For example, a user can articulately pull the closing trigger (26) towards the handle portion (20) to longitudinally convert the closing sleeve (32) towards the anvil (117) in response to the articulated extraction movement and the closing sleeve (32) provides the closure of the anvil (117). When the anvil (117) presses against the applicator portion (114A), the anvil subsurface (150) will be pressed against the gum (126), which will act as an adhesive to attach to the subsurface (150). In addition, pressing the anvil (117) against the applicator portion (114A) and platform (111) will propel the gel (128) into the pockets (119) of the platform (111). The pockets (119) filled with gel (128) are shown in FIG. 10, for example. Pressing the anvil (117) against the applicator portion (114A) and platform (111) will also deposit gel (128) substantially along a top surface of the platform (111).
    [0046] Additionally, when the anvil (117) is directed away from the cartridge platform (111) by the release of the closing trigger (26), which moves the closing sleeve (32) away from the anvil (117 ), the gum (126) will push the fabric (124) out of the upper portion (120) of the applicator portion (114A) and keep it on the subsurface (150) of the anvil (117). A user can then use the handle (110) to pull the applicator (106) away from the cartridge (113) and can then dispose of the applicator (106). When the applicator (106) is pulled out of the cartridge (113) in a direction substantially opposite the arrow (B) and when the cartridge (113) is outside a patient, the material (124, 126, 128) is applied to the end actuator (115), which is ready to use on a patient. FIG. 10 shows an end actuator (115) after the applicator (106) has been used to apply the material (124, 126, 128) to the end actuator (12).
    [0047] When the end actuator (115) is used in a manner similar to that described above for the end actuator (12), the firing bar (14) will slice the gel (128) and release the biocompatible gel (128) on the sliced layers (92, 94) of fabric (90). Simultaneously, the firing bar (14) will slice the backing fabric (124) and the adhesive gum (126) to release an auxiliary gel contained in the fabric (124) and the gum adhesive (126) in the sliced and separated fabric (90 ). In addition, the clips (47) will be directed through the material (124, 126, 128) and into the fabric (90) so that the clips (47) capture the material (124, 126, 128) and deposit it on the layers (92, 94) of fabric (90) as shown in FIG. 12. A new cartridge (113) can then be refilled and a new applicator (106) can be used to apply a new layer of material (124, 126, 128) to the end actuator (115) after each shot of the cartridge (113) through the end actuator (115).
    [0048] The gum (126) may comprise an adhesive such as, but not limited to, polymerizable and / or cross-linked materials such as a cyanoacrylate adhesive. The adhesive, for example, can be a monomeric adhesive composition (including prepolymeric), a polymeric adhesive composition or any other compound that can adhere to the fabric. In embodiments, the monomer can be a 1,1-disubstituted ethylene monomer, for example, an alpha-cyanoacrylate. When crosslinked or polymerized, cyanoacrylate can change from liquid to solid. Polymerized adhesives, for example, can be formulated to be flexible to rigid and could be spongy. If desired, the adhesive may be a single or dual part adhesive and / or may contain additives such as alternative compounds. The polymerization of the adhesive can occur from, but is not limited to, exposure to moisture, heat and / or adhesion initiators such as those described in US patent publication application No. 2009/0120994, the description of which is incorporated into reference title above. Other suitable materials and compositions that can be used to form the gum (124) will be apparent to those skilled in the art in view of the teachings of the present invention. III. Exemplary capillary action
    [0049] FIG. 13 shows a view of an exemplary cartridge (121), which has components similar to the cartridge (37) described above. The support (152) is arranged on the upper platform (153) of the cartridge (121) and can comprise a film, bladder, reservoir or other suitable material / structure. With reference to FIG. 13, the support (152) contains the antibiomaterial (154) which can comprise, for example, a liquid seal comprised of a hemostatic material as described above of application through capillary force to the tissue (90) perforated by the clamp (47) the cartridge (121). For example, when the clamp (47) directed by the wedge-shaped sliding support (41) and the driver (43) punctures through the support (152), a gap between the legs of the clamp (47) and the fabric (90) it can provide a path for a capillary force that can pull the antibiomaterial (154) along the legs of the clamp (47) and over the fabric (90). IV. Support bag filled with example glue
    [0050] FIG. 14 shows an exemplary cartridge (123) that has components substantially similar to the cartridge (37) described above. For example, the cartridge (123) includes a metal platform (127), with a longitudinal slot (125) passing through a central portion of a platform (127). The clips (47) are contained in a body or housing (129) of the cartridge (123) under the openings (not shown) formed in the platform (127) on each side of the slot (125). The cartridge (123) differs from the cartridge (37) as shown below.
    [0051] The cartridge (123) includes an envelope (156) disposed above the clips (47) in the housing (129) and below the platform (127). The envelope (156) is retained in a pocket (158) formed by internal walls of the housing (129) below the platform (127) and above the housed clips (47). The envelope (156) can comprise a glue-filled backing material comprised of an adhesive and backing material as described above for the gum (126) of the cartridge (113) and backing (100) of the cartridge (101) respectively. Of course, any other suitable materials and configurations can be used as apparent to the person skilled in the art in view of the teachings of the present invention.
    [0052] The firing bar (14) and clamps (47) can both be coated with a material, such as an adhesive or other biocompatible liquid material, to assist with the application of the envelope material (156) on the fabric (90 ), whose firing bar (14) is the staple separator (47) and the staple as described above for the cartridge (37). In addition, the glue on the envelope (156) can be replaced with a biological agent of fibrin or thrombin. For example, the firing bar (14) and clamps (47) can be coated with a material such as thrombin to react with the material retained in the envelope (156), which can be fibrin, for example, when the firing bar ( 14) and the staples (47) pierce the envelope (156). Alternative application of fibrin and thrombin is possible, so that the firing bar (14) and clips (47) are coated with fibrin and the envelope (156) comprises thrombin. In fact, a wide variety of synthetic and biological agents can be used. Such material can be applied to the cartridge (123) at a manufacturing site or sold separately and applied at a later stage. Alternatively, the cartridge (123) can include two compartments to contain two separate glues or any other biocompatible materials.
