Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to anastomosis devices. Background Technology

[0002] Anastomosing devices are medical devices used to replace manual suturing. Their main working principle is to use titanium staples to sever or anastomose tissue, similar to a stapler. Depending on their application, they can be mainly divided into skin anastomosing devices, digestive tract (esophagus, stomach, intestines, etc.) circular anastomosing devices, rectal anastomosing devices, circular hemorrhoid anastomosing devices, circumcision anastomosing devices, vascular anastomosing devices, hernia anastomosing devices, and lung cutting and suturing devices. Anastomosing devices can both close and cut incisions, and can also preserve blood supply to allow for tissue self-healing. However, after anastomosing and cutting incisions with an anastomosing device, there is still a certain percentage of cases of oral leakage and bleeding at the incision site. Summary of the Invention

[0009] The support plate is positioned inside the incision, and the actuating element extends out of the incision from the hole. The actuating element is configured to move the support plate toward the closed hole side when the anvil and the staple cartridge close the hole, so that the side of the biofilm away from the support plate adheres to the inside of the closed hole.

[0010] In one embodiment, the stapler further includes a cutting blade mounted between the anvil and the staple cartridge, the cutting blade being used to cut tissue and, in procedures using the first patch, to cut portions of the manipulator extending beyond the incision.

[0012] In one embodiment, the at least one patch further includes a second patch;

[0013] The second patch is used to be installed on the closed surface of the anvil or the closed surface of the staple cartridge. The anvil is configured to drive the second patch into the inside of the incision and close relative to the staple cartridge located on the outside of the incision, so that the second patch adheres to the mating surface inside the incision; or, the second patch is used to be installed on the closed surface of the staple cartridge, the staple cartridge being configured to drive the second patch into the inside of the incision and close relative to the anvil located on the outside of the incision, so that the second patch adheres to the mating surface inside the incision.

[0015] In one embodiment, each of the third patches is a tubular structure and is respectively used to be fitted onto the anvil and the nail cartridge, and each of the third patches includes a weak connection structure extending along the extension direction of the tubular structure;

[0016] The stapler is configured to move relative to the orifice to break the weak connection structure of the two third patches so that the sides of the two third patches away from the orifice can connect to each other to cover the anastomosis and the cutting surface.

[0017] In one embodiment, each of the third patches further includes a first portion and a second portion, with one side of the first portion and the second portion connected and the other side connected by the weak connection structure, the two first portions being used to adhere to both sides of the hole, and the two weak connection structures being located on the side away from the cut.

[0018] In one embodiment, the outer peripheral surface of each of the third patches is coated with a non-stick coating.

[0019] In one embodiment, each of the third patches has a connecting portion on the side near the shaft assembly, the connecting portion being used to connect to the root of the anvil or the root of the nail cartridge.

[0038] See Figure 1 and Figure 2 , Figure 1 A first schematic diagram of the anastomosis device provided in an embodiment of the present invention, wherein a first patch is selected for incision sealing according to the surgical procedure of hole closure suture; Figure 2This is a second schematic diagram illustrating the selection of a first patch for incision closure in an anastomosis device according to an embodiment of the present invention, based on the surgical procedure of hole closure suture. An anastomosis device according to an embodiment of the present invention includes a repair assembly 200 and an anastomosis device 100; the repair assembly 200 includes at least one patch, with various patches used for different surgical procedures; the anastomosis device 100 includes a shaft assembly 110, an anvil 120, and a staple cartridge 130, both the anvil 120 and the staple cartridge 130 being connected to the shaft assembly 110, and the anvil 120 and the staple cartridge 130 being able to close relative to each other; various patches are used to be installed on the anvil 120 or the staple cartridge 130; the anvil 120 and the staple cartridge 130 are configured to operate to the anastomosis position, and the patch is applied to the corresponding anastomosis to achieve closure and reinforcement.

[0039] Specifically, the patch in this application is of at least one type, which can be used in conjunction with the anvil 120 or the staple cartridge 130, so that the various patches can adhere to the corresponding anastomosis in their respective surgical procedures to achieve sealing and reinforcement, thereby reducing the problem of oral leakage and bleeding at the incision site 400, and improving the reliability and adaptability of the anastomosis equipment.

[0040] It should be noted that there are many types of surgical procedures, including incision closure for general trauma sites, incision closure for suturing of tubes such as the intestines, and incision closure for sealing holes.

[0041] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 3 This is a third schematic diagram of an anastomosis device provided in an embodiment of the present invention, in which a first patch is selected for incision sealing according to the surgical procedure of hole closure suture. Figure 4 This is a schematic diagram of a first patch in an anastomosis device according to an embodiment of the present invention. In one embodiment, at least one patch includes a first patch 210, which includes a support 300 and a biomembrane 211. The support 300 includes a support plate 320 and an operating member 310. The biomembrane 211 is disposed on one side of the support plate 320. The operating member 310 is connected to the support plate 320 and is disposed through the biomembrane 211. At least a portion of the structure of the operating member 310 extends to the side of the biomembrane 211 opposite to the support plate 320. The support plate 320 is used to be placed inside the incision 400, and the operating member 310 is used to extend out of the incision 400 from the hole 410. The operating member is configured to move the support plate toward the closed hole 410 when the anvil and staple cartridge close the hole 410, so that the side of the biomembrane 211 opposite to the support plate 320 adheres to the inside of the closed hole 410.

[0042] Specifically, the biomembrane 211 is made of biocompatible polymeric materials or biological materials, including but not limited to gelatin, cellulose, collagen, thrombin, fibrinogen, microporous polysaccharides, chitin, polylactic acid, polyglycolic acid, lactic acid-glycolic acid copolymer, polyacetin lactone, polydioxanone, etc. These materials may contain antibacterial drugs, hemostatic agents, growth promoters, or other therapeutic drugs. When the biomembrane 211 is obtained by combining the above materials and drugs and applied to the wound site, it can achieve hemostasis, cross-linking, and therapeutic effects. The biomembrane 211 has through holes for the operating member 310 to pass through, and the biomembrane 211 is installed on the support plate 320 through the through holes. The biomembrane 211 is biocompatible, allowing the side of the biomembrane 211 facing away from the support plate 320 to be compatible with biological tissue, thereby achieving an adhesive sealing effect. Preferably, the through holes are located at the center of the biomembrane 211.

[0043] When anastomosis of the hole 410 is required, the first patch 210 is selected. By placing the support plate 320 inside the blood vessel in the anastomosis hole 410 and extending the operating member 310 outside the hole 410, the anastomosing device 100 clamps and closes the hole 410. By pulling the operating member 310, the biofilm 211 can be adhered to the inner side of the closed hole 410. The inner side of the closed hole 410 can be sealed by the first patch 210, thereby reducing the risk of oral leakage or bleeding on the inner side of the hole 410 of the incision 400.

[0044] Furthermore, the biofilm 211 is contour-fitted to the support plate 320, thereby covering the inner side of the pore 410 to a greater extent. The structure formed by the biofilm 211 and the support plate 320 is similar to an adhesive tape structure, where the biofilm 211 is an adhesive and the support plate 320 is a support-supporting structure. However, the support plate 320 should be rigid to provide support and load-bearing function, but at the same time, it should also have a certain degree of flexibility so that when it is pulled by the operating element 310 to adhere to the tissue, it has a certain degree of tissue shape adaptability, allowing it to better adhere to the tissue. Preferably, the operating element 310 is a pull rope.

[0045] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the stapler 100 also includes a cutting blade mounted between the anvil 120 and the staple cartridge 130. The cutting blade is used to cut tissue and, in procedures using the first patch 210, to cut the portion of the manipulator 310 that extends beyond the incision 400.

[0046] Specifically, when the operating member 310 is pulled first, causing the side of the biofilm 211 facing away from the support plate 320 to adhere to the inside of the hole 410, and then the anastomosis device 100 closes the hole 410, the operating member 310 can be cut off by the cutting blade while removing excess tissue 450 at the anastomosis surface. When the operating member 310 is not pulled, the operating member 310 can be pulled by the cutting blade while the anastomosis device 100 closes the hole 410 into an anastomosis opening, so that the support plate 320 and the closed surface of the hole 410 are pressed together, and then the cutting blade cuts off the part of the operating member 310 that extends outside the hole 410.

[0047] See Figure 1 and Figure 4 In one embodiment, the support plate 320 and the operating component 310 are made of biodegradable materials, such as magnesium-aluminum alloy, polylactic acid, etc. In another embodiment, the support plate 320 and the operating component 310 are made of biocompatible materials, such as titanium alloy, etc. In yet another embodiment, the support plate 320 and the operating component 310 may also be made of other materials, such as polylactic acid, polyglycolic acid.

[0048] It should be noted that if the stent 300 is a non-degradable material, after the biofilm 211 degrades, the stent 300 remaining in the incision 400 will fall off and be excreted along with other substances in the gastrointestinal tract.

[0049] See Figure 5 , Figure 5 This is a schematic diagram illustrating the use of a second patch for incision closure in an anastomosis device according to an embodiment of the present invention, where the incision is closed based on a surgical procedure involving ductal tissue buttressing. In one embodiment, at least one patch further includes a second patch 220;

[0050] The second patch 220 is used to be installed on the closed surface of the anvil 120. The anvil is configured to drive the second patch 220 into the inside of the incision 400 and close relative to the staple cartridge 130 located on the outside of the incision 400, so that the second patch adheres to the anastomosis surface inside the incision; or, the second patch is used to be installed on the closed surface of the staple cartridge 130, which is configured to drive the second patch 220 into the inside of the incision 400 and close relative to the anvil 120 located on the outside of the incision 400, so that the second patch 220 adheres to the anastomosis surface inside the incision 400.

[0051] Specifically, the second patch 220 is made of the same material as the biofilm 211. The second patch 220 is installed on the closed surface of the anvil 120 or the closed surface of the stapler cartridge 130, so that the second patch 220 can be applied to the anastomotic incision 400 via the stapler 100 to seal the incision 400. Preferably, the second patch 220 is installed on the closed surface of the anvil 120.

[0052] In this procedure, when two tubes are connected, after the two tubes are anastomosed, the two incisions 400 within the anastomotic connection site need to be sealed. Therefore, a second patch 220 is selected and adhered to the closed surface of the anvil 120. Then, the anvil 120 is inserted through the hole 410 into the incision 400 within the tube connection site. The anvil 120 and the staple cartridge 130 are used to close and clamp the incision, thereby applying the second patch 220 to the incision 400 to seal it and reduce the risk of oral leakage or bleeding at the incision 400. In this procedure, two second patches 220 are needed to seal the two incisions 400 formed by the anastomosis.

[0053] It should be noted that the second patch 220 can be adhered to the closed surface of the anvil 120 or the closed surface of the staple cartridge 130, but the adhesion of the second patch 220 to the tissue is greater than that of the second patch 220 to the closed surface of the anvil 120 or the closed surface of the staple cartridge 130. Therefore, after the second patch 220 is adhered to the anastomosis line, when the stapler 100 is removed, the second patch 220 can still be stably adhered to the incision site and will not be taken out by the anvil 120 or the staple cartridge 130.

[0054] See Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 6 A first schematic diagram of selecting a third patch for incision closure in an anastomosis device provided in an embodiment of the present invention when the incision is closed by tissue suturing of a general trauma site according to the surgical procedure; Figure 7 This is a second schematic diagram of the selection of a third patch for incision closure in the anastomosis device provided in an embodiment of the present invention when the incision is closed by tissue suturing of a general trauma site according to the surgical procedure; Figure 8 This is a third schematic diagram of the anastomosis device provided in an embodiment of the present invention, in which a third patch is selected for incision sealing when the incision is sutured at a general trauma site according to the surgical procedure. Figure 9 This is a schematic diagram of a third patch in an anastomosis device according to an embodiment of the present invention. In one embodiment, at least one patch further includes two third patches 230, which are respectively disposed on the closed surface of the anvil 120 and the closed surface of the staple cartridge 130; the anvil 120 and the staple cartridge 130 are configured to mate with the outer side of the hole 410 to staple the two third patches 230 to both sides of the anastomosed hole 410.

[0055] Specifically, the closed surfaces of the third patch 230 with the anvil 120 and the nail cartridge 130 can be adhesively connected, so that the two third patches 230 can be stably adhered to the closed surfaces of the anvil 120 and the nail cartridge 130 respectively, wherein the third patch 230 is made of the same material as the biofilm 211.

[0056] Specifically, when anastomotic hole 410 is closed, a third patch 230 is selected. Two third patches 230 are first placed on the closed surfaces of the anvil 120 and the staple cartridge 130, respectively. When the anvil 120 and the staple cartridge 130 are clamped together to close the anastomotic hole 410, while the first patch 210 is used to seal the inner side of the closed area of ​​the hole 410, the third patch 230 is used to seal the outer incision 400 of the closed area of ​​the hole 410. This makes the incision 400 more secure and reduces the risk of oral leakage or bleeding at the incision 400.

[0057] See Figure 6 , Figure 7 and Figure 9 In one embodiment, each third patch 230 is a tubular structure that can be fitted onto the anvil 120 and the staple cartridge 130. Each third patch 230 includes a weak connection structure 233 extending along its tubular structure. The stapler 100 is configured to move relative to the hole 410 to break the weak connection structure 233 of the two third patches 230 so that the sides of the two third patches 230 away from the hole 410 can connect to each other to cover the anastomosis and the cutting surface.

[0058] Specifically, the weak connection structure 233 is designed so that when the third patch 230 is applied to the incision 400 and the jaws of the stapler 100 are opened, even when the anvil 120 and staple cartridge 130 are relatively far apart, the tensile force exerted by the anvil 120 and staple cartridge 130 on the third patch 230 can easily cause the third patch 230 to break at the weak connection structure 133, thereby allowing the anvil 120 and staple cartridge 130 to detach from the third patch 230, that is, to dislodge from the tubular structure formed by the third patch 230. Because the weak connection structure 233 of the two third patches 230 breaks, the sides of the two third patches 230 away from the hole 410 can connect to each other, thereby covering the anastomosis surface and the incision 440, thus reducing the risk of oral leakage or bleeding at the incision 400.

[0059] See Figure 6 , Figure 7 and Figure 9In one embodiment, each third patch 230 further includes a first portion 231 and a second portion 232, with one side of the first portion 231 and the second portion 232 connected and the other side connected by a weak connection structure 233. The two first portions 231 are used to adhere to both sides of the hole 410, and the two weak connection structures 233 are located on the side away from the cut 400.

[0060] Specifically, the third patch 230 includes a first part 231 and a second part 232 that are interconnected, and the two sides of the weak connection structure 233 are connected to the first part 231 and the second part 232, respectively. The two third patches 230 are sleeved on the anvil 120 and the staple cartridge 130, and the first part 231 of the two third patches 230 corresponds to the closed surface of the anvil 120 and the closed surface of the staple cartridge 130, respectively. When the anvil 120 and staple cartridge 130 clamp the tissue suture at the wound site, the two first parts 231 can be stapled to the anastomosis site along with the staples. Then, when the stapler 100 is operated to open the jaws, even when the anvil 120 and staple cartridge 130 are relatively far apart, the pulling force formed by the anvil 120 and staple cartridge 130 on the third patch 230 causes the third patch 230 to break from the weak connection structure 133. This allows the anvil 120 and staple cartridge 130 to detach from the third patch 230, that is, to dislodge from the tubular structure formed by the third patch 230. Then, by closing the jaws of the stapler 100 again, the anvil 120 and staple cartridge 130 tighten the two second parts 232, so that the two second parts 232 adhere to each other on the side closest to the weak connection structure 233, covering the anastomosis surface and the incision 440, thereby reducing the risk of oral leakage or bleeding at the incision 440.

[0061] It should be noted that, due to the characteristics of the stapler 100 itself, the outer contour area of ​​the second part 232 is larger than that of the first part 231. Therefore, after the weak connection structure 233 is broken, the length of the second part 232 is greater than that of the corresponding first part 231, so that the two second parts 232 can cover the cutting surface 440 and the abutment surface, and the two second parts 232 can be bonded to each other on the side closer to the weak connection structure 233.

[0062] See Figure 6 , Figure 7 and Figure 8 In one embodiment, the outer peripheral surface of each third patch 230 is coated with a non-stick coating, thereby preventing other tissues from adhering to the side of each third patch 230 away from the anvil 120 or the cartridge 130, or causing the two third patches 230 to stick together when the jaws are closed, thus affecting the stability of each third patch 230 fitted onto the anvil 120 or the cartridge 130.

[0063] See Figure 6In one embodiment, each third patch 230 is provided with a connecting portion on the side near the shaft assembly 110. The connecting portion is used to connect to the root of the anvil 120 or the root of the nail cartridge 130, so that each third patch 230 is stably connected to the anvil 120 or the nail cartridge 130 through the connecting portion, preventing the third patch 230 from falling out of the anvil 120 or the nail cartridge 130, and improving the stability and reliability of the connection.

[0064] It should be noted that the connecting portion can be multiple spaced protrusions, thereby increasing the friction between the third patch 230 and the anvil 120 or the nail cartridge 130, thus ensuring a stable connection between the third patch 230 and the anvil 120 or the nail cartridge 130. In other embodiments, the connecting portion can be anything else, as long as it can improve the stability of the connection between the third patch 230 and the anvil 120 or the nail cartridge 130.

[0065] See Figure 1 and Figure 2 In one embodiment, the present invention also provides a method of using the above-described anastomosis device, the method comprising the following steps:

[0066] S100 selects the appropriate patch based on the surgical procedure.

[0067] S200 installs the patch on the anvil 120 or the staple cartridge 130.

[0068] S300 operates the anvil 120 and staple cartridge 130 to the anastomosis position, and applies the patch to the corresponding anastomosis to achieve sealing and reinforcement.

[0069] Specifically, the patch in this application is of at least one type. The corresponding patch is selected according to the surgical procedure. Then, the various patches are used in conjunction with the anvil 120 and the staple cartridge 130 so that the various patches adhere to the corresponding anastomosis under the corresponding surgical procedure, thereby reducing the problem of oral leakage and bleeding at the incision 400.

[0070] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, at least one patch includes a first patch 210, the first patch 210 including a scaffold 300 and a biomembrane 211, the scaffold 300 including a support plate 320 and an actuating element 310, the biomembrane 211 being disposed on one side of the support plate 320, the actuating element 310 being connected to the support plate 320 and extending through the biomembrane 211, at least a portion of the structure of the actuating element 310 extending to the side of the biomembrane 211 opposite to the support plate 320; when the first patch 210 is selected according to the surgical procedure, the method further includes:

[0071] S111 places the support plate 320 inside the cut 400, and makes the side of the biofilm 211 away from the support plate 320 face the hole 410 of the cut 400, and makes the operating member 310 extend out of the cut 400 from the hole 410.

[0072] S112 closes the hole 410 of the cut 400 through the anvil 120 and the nail cartridge 130;

[0073] S113 pulls the operating component 310 and connects the closed hole 410 to form an anastomosis, wherein the side of the biofilm 211 facing away from the support plate 320 adheres to the inside of the anastomosis.

[0074] S114 cuts off the portion of the operating piece 310 that extends beyond the incision 400 using the cutting blade of the stapler 100.

[0075] Specifically, when anastomosis of the hole 410 is required, the first patch 210 is selected. By placing the support plate 320 inside the incision 400 and extending the operating member 310 outside the hole 410, the stapler 100 clamps the outer wound surface 420 of the hole 410 so that after the hole 410 is closed, the biofilm 211 can be adhered to the closed surface of the hole 410 by pulling the operating member 310. After the hole 410 is anastomosed by the stapler 100 to form the first anastomosis surface 430 and the part of the operating member 310 extending outside the hole 410 is cut, the closed surface inside the hole 410 can be completely sealed, thereby reducing the risk of oral leakage or bleeding at the hole 410 of the incision 400.

[0076] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, S113 specifically includes:

[0077] Pulling the operating component 310 causes the side of the biofilm 211 away from the support plate 320 to adhere to the inside of the hole 410, and then the anastomosing device 100 closes the closed hole 410.

[0078] Specifically, the anvil 120 and staple cartridge 130 first clamp the external wound surfaces 420 on both sides of the hole 410 to close the hole 410. Then, the operating component 310 is manually pulled or pulled by other means so that the operating component 310 can drive the support plate 320 to move towards the closed surface of the hole 410. When the support plate 320 abuts against the closed surface of the hole 410, the biofilm 211 will be stably adhered to the closed surface of the hole 410 under the push of the support plate 320. Then, when the anastomosing device 100 anastomoses the hole 410, the cutting blade can cut the operating component 310 when removing the excess tissue 450 of the anastomosing surface.

[0079] In another embodiment, S113 specifically includes: while the anastomosis device 100 closes the closed hole 410 into an anastomosis opening, the operating member 310 is pulled so that the side of the biofilm 211 facing away from the support plate 320 adheres to the inside of the anastomosis opening.

[0080] Specifically, when the stapler 100 clamps and closes the two external wound surfaces 420 on the outside of the hole 410, but does not pull the operating member 310, there is a certain distance between the support plate 320 and the closed surface of the hole 410. When the stapler 100 mates with the hole 410 to form the first mate surface 430 and the cutter cuts the excess tissue 450, the cutter will first pull the operating member 310 to move, so that the support plate 320 and the closed surface of the hole 410 are pressed together, and then the cutter cuts the operating member 310.

[0081] See Figure 5 In one embodiment, at least one patch further includes a second patch 220, and when the second patch 220 is selected according to the surgical procedure, the method further includes:

[0082] S121 inserts the anvil 120 and the staple cartridge 130 into the inside of the hole 410 and mates the other parts outside the hole 410 inside the cut 400;

[0083] S122 attaches the second patch 220 to the closed surface of the anvil 120;

[0084] S123 inserts the anvil 120 into the inside of the hole 410 and clamps it with the staple cartridge 130 to adhere the second patch 220 to the mating surface inside the cut 400.

[0085] Specifically, when it is necessary to anastomose two parts of tissue within the incision 400, a second patch 220 is selected. First, the anvil 120 and the staple cartridge 130 are inserted into the hole 410 to anastomose the parts of the incision 400 other than the hole 410, forming a second anastomosis surface 460. Then, the second patch 220 is adhered to the closed surface of the anvil 120. The anvil 120 is then inserted into the hole 410 of the incision 400 and aligned with the second anastomosis surface 460 within the hole 410. The anvil 120 and the staple cartridge 130 are closed and clamped, so that the side of the second patch 220 facing away from the staple cartridge 130 can be stably adhered to the second anastomosis surface 460, thereby sealing the second anastomosis surface 460 and reducing the risk of oral leakage or bleeding at the second anastomosis surface 460.

[0086] Furthermore, the second patch 220 can be used in conjunction with the first patch 210. That is, before S111, the second patch 220 is selected first, and the part inside the hole 410 of the incision 400 is anastomosed into the second anastomotic surface 460. After the second patch 220 is adhered to the second anastomotic surface 460, the first patch 210 is used to seal the hole 410, thereby further reducing the risk of oral leakage or bleeding in the incision 400.

[0087] See Figure 6 , Figure 7 , Figure 8 and Figure 9 In one embodiment, at least one patch further includes two third patches 230, and when the third patch 230 is selected according to the surgical procedure, the method further includes:

[0088] S131 attaches two third patches 230 to the anvil 120 and the staple cartridge 130 respectively;

[0089] S132 uses the stapler 100 to staple the hole 410 to attach the two third patches 230 to both sides of the stapled hole 410.

[0090] Specifically, when the anastomosis hole 410 needs to be closed, the third patch 230 is selected. First, the two third patches 230 are respectively attached to the anvil 120 and the staple cartridge 130. Then, when the anastomosis hole 410 is closed by the stapler 100 to form the third anastomosis surface, the two third patches 230 can be stapled to the third anastomosis surface on both sides of the closed hole 410, thereby making the third anastomosis surface more secure and reducing the risk of oral leakage or bleeding at the third anastomosis surface.

[0091] Furthermore, when anastomosing the hole 410, the third patch 230 can be combined with the first patch 210. That is, before S112, the two third patches 230 are first adhered to the anvil 120 and the staple cartridge 130 respectively. Then, when the stapler 100 anastomoses the hole 410 and the biofilm 211 is adhered to the closed surface of the hole 410, the two third patches 230 can be stapled to the two first anastomotic surfaces 430, further reducing the risk of oral leakage or bleeding at the first anastomotic surface 430.

[0092] Furthermore, the third patch 230, the first patch 210, and the second patch 220 can be used in combination to reduce the risk of oral leakage or bleeding at each anastomosis site and improve the adaptability of the stapler 100.

[0093] See Figure 6 , Figure 7 , Figure 8 and Figure 9In one embodiment, the third patch 230 is annular and includes a weak connection structure 233 extending along its centerline; in S131, specifically, the method includes: fitting two third patches 230 onto the anvil 120 and the staple cartridge 130 respectively; after S132, the method further includes:

[0094] S133 removes the stapler 100 to break the weak connection structure 233 of the two third patches 230;

[0095] S134 connects the two third patches 230 to each other on the side away from the hole 410 to cover the anastomosis and the cut surface 440.

[0096] Specifically, the third patch 230 includes a first part 231 and a second part 232 that are interconnected, and the two sides of the weak connection structure 233 are connected to the first part 231 and the second part 232, respectively. Two third patches 230 are fitted onto the anvil 120 and the staple cartridge 130. The first parts 231 of the two third patches 230 correspond to the closed surfaces of the anvil 120 and the staple cartridge 130, respectively, and the two weak connection structures 233 are located on the side away from the incision 400. When the anvil 120 and the staple cartridge 130 are clamped and mate with the hole 410, the two first parts 231 can be stapled to both sides of the mate hole 410, and excess tissue 450 is cut to form a cutting surface 440. Then, by removing the stapler 100, the two weak connection structures 233 are ruptured.

[0097] In this process, some excess tissue 450 is cut off, so that the second part 232 of the two third patches 230 can cover the corresponding third anastomosis surface, and the side of the second part 232 near the weak connection structure 233 can adhere to each other and cover the cut surface 440. This allows the closure surface of the hole 410 to be sealed, while the outside of the hole 410 is also covered, further reducing the risk of oral leakage or bleeding at the anastomosis of the hole 410.

[0098] In this application, the first patch 210, the second patch 220, and the third patch 230 are respectively adhered to the corresponding anastomosis under the corresponding surgical procedures, and the bonding between the first patch 210, the second patch 220, and the third patch 230 is achieved.

[0099] This further reduces the problem of oral leakage and bleeding at 400 incision sites, and improves the reliability and adaptability of the anastomosis equipment.
