[0038] See also Figure 1 and Figure 2 , Figure 1 A first schematic diagram of selecting a first patch for incision occlusion according to the incision occlusion procedure of hole closure suture in the anastomosis device provided by one embodiment of the present invention; Figure 2A second schematic diagram of the anastomosis device provided in one embodiment of the present invention, when the first patch is selected for incision occlusion according to the surgical procedure of hole closure suture incision occlusion. The anastomosis device provided in one embodiment of the present invention comprises a repair assembly 200 and a stapler 100; the repair assembly 200 comprises at least one patch, and various patches are respectively used for different surgical procedures; the stapler 100 comprises an axis assembly 110, an anvil 120 and a stapler 130, the anvil 120 and the stapler 130 are both connected to the axis assembly 110, the anvil 120 and the stapler 130 can be relatively closed, various patches are used to be installed on the anvil 120 or the stapler 130, the anvil 120 and the stapler 130 are configured to be operated to the anastomotic position, and the patches are applied to the corresponding anastomotic openings through operation to achieve occlusion reinforcement.

[0039] Specifically, the patch in the present application is at least one kind, so that it can cooperate with the anvil 120 or the nail magazine 130, so that various patches can adhere to the corresponding anastomotic opening under their corresponding surgical procedures to achieve closure and reinforcement, thereby reducing the problem of a certain proportion of fistula and bleeding at the incision 400, and improving the reliability and adaptability of the anastomotic device.

[0040] It should be noted that there are many types of surgical procedures, including incision closure by suturing tissues at general trauma sites, incision closure by docking and suturing of tubular tissues such as the intestines, and incision closure by closing and suturing holes.

[0041] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 3 A third schematic diagram of the anastomosis device provided in one embodiment of the present invention when the first patch is selected for incision occlusion according to the incision occlusion procedure of hole closure suture; Figure 4 A schematic diagram of a first patch in an anastomosis device provided in an embodiment of the present invention. In one embodiment, at least one patch includes a first patch 210, the first patch 210 includes a support 300 and a biofilm 211, the support 300 includes a support plate 320 and an operating member 310, the biofilm 211 is arranged on one side of the support plate 320, the operating member 310 is connected to the support plate 320 and is arranged through the biofilm 211, and at least part of the structure of the operating member 310 extends to the side of the biofilm 211 away from the support plate 320; the support plate 320 is used to be placed on the inner side of the incision 400, the operating member 310 is used to extend from the hole 410 outside the incision 400, and the operating member is configured to drive the support plate to move toward the side of the closed hole 410 when the anvil and the nail magazine close the hole 410, so that the side of the biofilm 211 away from the support plate 320 adheres to the inner side of the closed hole 410.

[0042] Specifically, the biofilm 211 is made of a biocompatible polymer material or biomaterial, including but not limited to gelatin, cellulose, collagen, thrombin, fibrinogen, microporous polysaccharide, chitin, polylactic acid, polyglycolic acid, lactic acid-glycolic acid copolymer, polyacetic acid lactone, polydioxanone, etc., and these materials may contain antibacterial drugs, hemostatic drugs, growth-promoting drugs or other therapeutic drugs. When the biofilm 211 is obtained by combining the above materials and drugs, it can achieve coagulation, cross-linking, treatment and other effects when attached to the wound site. The biofilm 211 has a through hole for the operating member 310 to pass through, and the biofilm 211 is passed through the operating member 310 through the through hole, so as to be installed on the support plate 320. The biofilm 211 has biocompatibility, so that the side of the biofilm 211 away from the support plate 320 can be compatible with biological tissues, thereby playing a role of bonding and blocking. Preferably, the through hole is located in the center of the biofilm 211.

[0043] Among them, when it is necessary to anastomose the hole 410, the first patch 210 is selected. The support plate 320 can be placed inside the blood vessel in the anastomotic hole 410, and the operating member 310 can be extended out of the hole 410, so that after the anastomosis device 100 clamps the hole 410 closed, the operating member 310 can be pulled to make the biofilm 211 adhere to the inner side of the closed hole 410, and the inner side of the closed hole 410 can be blocked by the first patch 210, thereby reducing the risk of fistula or bleeding on the inner side of the hole 410 of the incision 400.

[0044] Furthermore, the biofilm 211 is adapted to the contour of the support plate 320, so that the inner side of the hole 410 can be covered to a greater extent. The structure formed by the biofilm 211 and the support plate 320 is similar to that of the biofilm 211 being a viscose and the support plate 320 being a tape-like structure that carries the viscose matrix. However, the support plate 320 should have rigidity to support and carry the load, but at the same time should have a certain flexibility so that when it is pulled by the operating member 310 to be attached to the tissue, it has a certain adaptability to the tissue shape so that it can be better attached to the tissue. Preferably, the operating member 310 is a pull rope.

[0045] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the stapler 100 further includes a cutting knife installed between the anvil 120 and the staple magazine 130, the cutting knife being used for cutting tissue, and also for cutting the portion of the operating member 310 extending outside the incision 400 in a procedure using the first patch 210.

[0046] Specifically, when the operating member 310 is first pulled so that the side of the biofilm 211 facing away from the support plate 320 adheres to the inner side of the hole 410, the operating member 310 can be cut off by the cutting knife when the redundant tissue 450 on the anastomosis surface is removed when the closed hole 410 is anastomosed by the stapler 100. When the operating member 310 is not pulled, the operating member 310 can be pulled by the cutting knife while the closed hole 410 is anastomosed into an anastomotic opening by the stapler 100, so that the support plate 320 and the closed surface of the hole 410 are pressed tightly, and then the cutting knife cuts off the part of the operating member 310 extending out of the hole 410.

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

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

[0049] See also Figure 5 , Figure 5 A schematic diagram of selecting a second patch for incision closure according to the incision closure of tube tissue butt suture in an anastomosis device provided in an embodiment of the present invention. 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 closing surface of the anvil 120, and the anvil is configured to drive the second patch 220 to extend into the inner side of the incision 400, and to close relatively with the nail magazine 130 located on the outside of the incision 400, so that the second patch adheres to the matching surface on the inner side of the incision; or, the second patch is used to be installed on the closing surface of the nail magazine 130, and the nail magazine 130 is configured to drive the second patch 220 to extend into the inner side of the incision 400, and to close relatively with the nail anvil 120 located on the outside of the incision 400, so that the second patch 220 adheres to the matching surface on the inner side of the incision 400.

[0051] Specifically, the second patch 220 is made of the same material as the biofilm 211, and is installed on the closed surface of the anvil 120 or the closed surface of the staple cartridge 130, so that the second patch 220 can be applied to the incision 400 after the anastomosis by the stapler 100 to achieve the occlusion of the incision 400. Preferably, the second patch 220 is installed on the closed surface of the anvil 120.

[0052] Among them, when the operation is to connect two tube tissues, after the two tube tissues are anastomosed, it is necessary to seal the two incisions 400 in the connection position of the tube tissue formed by the anastomosis, so the second patch 220 is selected, and the second patch 220 is adhered to the closed surface of the anvil 120, and then the anvil 120 is extended from the hole 410 into the incision 400 in the connection position of the tube tissue, and the anvil 120 and the nail magazine 130 are closed and clamped, so that the second patch 220 is applied to the incision 400, so as to achieve the sealing of the incision 400 and reduce the risk of fistula or bleeding at the incision 400; under this procedure, two second patches 220 are required to respectively 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 stapler 130, but the adhesion of the second patch 220 to the tissue is greater than the adhesion of the second patch 220 to the closed surface of the anvil 120 or the closed surface of the stapler 130, so that after the second patch 220 is adhered to the staple line, when the stapler 100 is removed, the second patch 220 can still be stably adhered to the incision and will not be removed by the anvil 120 or the stapler 130.

[0054] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9 , Figure 6 A first schematic diagram of selecting a third patch for incision sealing according to the surgical procedure of tissue suturing at a general wound site in the anastomosis device provided by one embodiment of the present invention; Figure 7 A second schematic diagram of the anastomosis device provided in one embodiment of the present invention when the third patch is selected for incision sealing according to the surgical procedure of incision sealing for tissue suturing at a general wound site; Figure 8 A third schematic diagram of the anastomosis device provided in one embodiment of the present invention when a third patch is selected for incision sealing according to the surgical procedure of incision sealing for tissue suturing at a general wound site; Fig. 9 A schematic diagram of a third patch in a stapling device provided in an embodiment of the present invention. In one embodiment, at least one patch further includes two third patches 230, and the two third patches 230 are respectively used to be arranged 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 be stapled relative to the outside of the hole 410, so as to staple the two third patches 230 to both sides of the stapling hole 410.

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

[0056] Among them, when anastomosing the hole 410, the third patch 230 is selected, and the two third patches 230 are first respectively set on the closing surface of the anvil 120 and the closing surface of the nail magazine 130, and the anvil 120 and the nail magazine 130 are clamped to close the anastomotic hole 410. When the first patch 210 is used to block the inner side of the closed part of the hole 410, the third patch 230 is used to block the outer incision 400 of the closed part of the hole 410, thereby making the incision 400 more secure and reducing the risk of fistula or bleeding at the incision 400.

[0057] See also Figure 6 , Figure 7 and Fig. 9 In one embodiment, each third patch 230 is a tubular structure that can be sleeved on the anvil 120 and the stapler 130, and each third patch 230 includes a weak connection structure 233 along the extension direction of 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 two third patches 230 can be connected to each other on the side away from the hole 410 to cover the anastomotic opening and the cutting surface.

[0058] Specifically, the weak connection structure 233 is used for when the third patch 230 is applied to the incision 400 and the stapler 100 is operated to open the jaws, even if the anvil 120 and the staple cartridge 130 are relatively far apart, the pulling force on the third patch 230 formed by the anvil 120 and the staple cartridge 130 can easily cause the third patch 230 to break from the weak connection structure 133, so that the anvil 120 and the staple cartridge 130 can be separated from the third patch 230, that is, out of the tubular structure formed by the third patch 230. Since the weak connection structures 233 of the two third patches 230 are broken, the sides of the two third patches 230 away from the hole 410 can be connected to each other, so as to cover the anastomotic surface and the incision 440, thereby reducing the risk of fistula or bleeding at the incision 400.

[0059] See also Figure 6 , Figure 7 and Fig. 9In one embodiment, each third patch 230 also includes a first part 231 and a second part 232, the first part 231 and the second part 232 are connected on one side and connected on the other side by a weak connection structure 233, the two first parts 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 incision 400.

[0060] Specifically, the third patch 230 includes a first portion 231 and a second portion 232 connected to each other, and two sides of the weak connection structure 233 are respectively connected to the first portion 231 and the second portion 232. The two third patches 230 are sleeved on the anvil 120 and the nail magazine 130, and the first portions 231 of the two third patches 230 correspond to the closed surfaces of the anvil 120 and the closed surfaces of the nail magazine 130, respectively. When the anvil 120 and the stapler 130 are clamped to suture the tissue at the wound site, the two first parts 231 can be stapled to the anastomosis site along with the staplers. Then, when the stapler 100 is operated to open the jaws, even if the anvil 120 and the stapler 130 are relatively far apart, the pulling force on the third patch 230 formed by the anvil 120 and the stapler 130 causes the third patch 230 to break from the weak connection structure 133, so that the anvil 120 and the stapler 130 can be separated from the third patch 230, that is, out of the tubular structure formed by the third patch 230. Then, by closing the jaws of the stapler 100 again, the anvil 120 and the stapler 130 tighten the two second parts 232, so that the two second parts 232 are bonded to each other on the sides close to the weak connection structure 233, covering the anastomosis surface and the incision 440, thereby reducing the risk of fistula 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 the outer contour area of ​​the first part 231. Therefore, after the weak connection structure 233 is disconnected, the length of the second part 232 is greater than the corresponding first part 231, so that the two second parts 232 can cover the cutting surface 440 and the mating surface, and the two second parts 232 can be bonded to each other on one side close to the weak connection structure 233.

[0062] See also Figure 6 , Figure 7 and Figure 8 In one embodiment, the outer peripheral surface of each third patch 230 is provided with a non-stick coating, so as to prevent the side of each third patch 230 facing away from the anvil 120 or the nail magazine 130 from adhering to other tissues or causing the two third patches 230 to stick to each other when the jaws are closed, thereby affecting the stability of each third patch 230 being mounted on the anvil 120 or the nail magazine 130.

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

[0064] It should be noted that the connection portion may be a plurality of spaced protrusions, so as to increase the friction between the third patch 230 and the anvil 120 or the nail magazine 130, so that the third patch 230 is stably connected to the anvil 120 or the nail magazine 130. In other embodiments, the connection portion may be other, as long as it can improve the stability of the connection between the third patch 230 and the anvil 120 or the nail magazine 130.

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

[0066] S100 selects the corresponding patch according to the surgical procedure.

[0067] S200 installs the patch on the anvil 120 or the nail magazine 130 .

[0068] S300: The anvil 120 and the staple cartridge 130 are moved to the anastomotic position, and a patch is applied to the corresponding anastomotic position to achieve occlusion reinforcement.

[0069] Specifically, there is at least one kind of patch in the present application, and the corresponding patch is selected according to the surgical procedure, and then various patches are coordinated with the anvil 120 and the nail magazine 130, so that various patches are adhered to the corresponding anastomosis under their corresponding surgical procedures, thereby reducing the problem of a certain proportion of fistula and bleeding at the incision 400.

[0070] See also 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 includes a support 300 and a biofilm 211, the support 300 includes a support plate 320 and an operating member 310, the biofilm 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 biofilm 211, and at least a portion of the structure of the operating member 310 extends to a side of the biofilm 211 away from the support plate 320; when the first patch 210 is selected according to the surgical procedure, the method further includes:

[0071] S111: placing the support plate 320 inside the incision 400, and making the side of the biofilm 211 away from the support plate 320 face the hole 410 of the incision 400, and making the operating member 310 extend out of the incision 400 from the hole 410;

[0072] S112 closes the hole 410 of the incision 400 by using the anvil 120 and the nail magazine 130;

[0073] S113: Pull the operating member 310 to anastomose the closed hole 410 into an anastomotic opening, wherein the side of the biofilm 211 facing away from the support plate 320 adheres to the inner side of the anastomotic opening;

[0074] S114: The portion of the operating member 310 extending outside the incision 400 is cut off by the cutting knife of the stapler 100.

[0075] Specifically, when the hole 410 needs to be anastomosed, the first patch 210 is selected. By placing the support plate 320 on the inner side of the incision 400 and extending the operating member 310 out of 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 operating member 310 can be pulled to make the biofilm 211 adhere to the closed surface of the hole 410. After the hole 410 is anastomosed by the stapler 100 to form the first anastomotic surface 430 and the portion of the operating member 310 extending out of the hole 410 is cut, the closed surface inside the hole 410 can be completely blocked, thereby reducing the risk of fistula or bleeding at the hole 410 of the incision 400.

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

[0077] The operating member 310 is pulled to make the side of the biological membrane 211 facing away from the support plate 320 adhere to the inner side of the hole 410 , and then the closed hole 410 is anastomosed by the stapler 100 .

[0078] Specifically, the anvil 120 and the staple magazine 130 first clamp the external wound surface 420 on both sides of the hole 410 to close the hole 410, and then pull the operating member 310 manually or by other means, so that the operating member 310 can drive the support plate 320 to move toward 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, and then when the hole 410 is anastomosed by the stapler 100, the cutting knife can cut off the operating member 310 when removing excess tissue 450 on the anastomosis surface.

[0079] In another embodiment, in S113, it specifically includes: while anastomosing the closed hole 410 into a stoma by the stapler 100, pulling the operating member 310 so that the side of the biofilm 211 facing away from the support plate 320 adheres to the inner side of the stoma.

[0080] Specifically, when the stapler 100 clamps the two external wound surfaces 420 on the outside of the hole 410 closed 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. Then, when the stapler 100 staples the hole 410 into a first stapled surface 430 and the cutting knife cuts excess tissue 450, the cutting knife will first pull the operating member 310 to move, so that the support plate 320 is pressed against the closed surface of the hole 410, and then the cutting knife will cut off the operating member 310.

[0081] See also Figure 5 In one embodiment, at least one patch further comprises a second patch 220. When the second patch 220 is selected according to the procedure, the method further comprises:

[0082] S121: extending the nail anvil 120 and the nail magazine 130 into the inner side of the hole 410, and anastomosing the other parts of the inner side of the incision 400 except the hole 410;

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

[0084] S123 extends the anvil 120 into the inner side of the hole 410 and clamps it with the nail magazine 130 to adhere the second patch 220 to the anastomotic surface inside the incision 400 .

[0085] Specifically, when it is necessary to anastomose two parts of tissue in the incision 400, the second patch 220 is selected. First, the anvil 120 and the nail magazine 130 need to be extended into the inner side of the hole 410 to anastomose the other parts of the incision 400 other than the hole 410 to form a second anastomotic surface 460, and then the second patch 220 is adhered to the closed surface of the anvil 120, and then the anvil 120 is extended into the hole 410 of the incision 400 and aligned with the second anastomotic surface 460 in the hole 410, and the anvil 120 and the nail magazine 130 are closed and clamped, so that the side of the second patch 220 away from the nail magazine 130 can be stably adhered to the second anastomotic surface 460, so that the second anastomotic surface 460 can be blocked, and the risk of fistula or bleeding on the second anastomotic surface 460 is reduced.

[0086] Furthermore, the second patch 220 can be used in combination with the first patch 210, that is, before S111, the second patch 220 is first selected, the part inside the hole 410 of the incision 400 is anastomosed into a second anastomotic surface 460, and after the second patch 220 is adhered to the second anastomotic surface 460, the first patch 210 is used to block the hole 410, thereby further reducing the risk of fistula or bleeding in the incision 400.

[0087] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9 In one embodiment, the at least one patch further comprises two third patches 230. When the third patches 230 are selected according to the procedure, the method further comprises:

[0088] S131: Adhere the two third patches 230 to the anvil 120 and the nail magazine 130 respectively;

[0089] S132: The hole 410 is stapled by the stapler 100, so as to staple the two third patches 230 to the two sides of the stapled hole 410.

[0090] Specifically, when the hole 410 needs to be anastomosed, the third patch 230 is selected. First, the two third patches 230 are respectively adhered to the anvil 120 and the stapler 130, and then when the hole 410 is anastomosed by the stapler 100 to form a third anastomotic surface, the two third patches 230 can be stapled to the third anastomotic surface on both sides of the hole 410 after anastomosis, so that the third anastomotic surface is more firm and the risk of fistula or bleeding on the third anastomotic surface is reduced.

[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 respectively adhered to the anvil 120 and the nail magazine 130. Then, when the stapler 100 anastomoses the hole 410 and adheres the biofilm 211 to the closed surface of the hole 410, the two third patches 230 can be nailed to the two first anastomotic surfaces 430 and the third anastomotic surface, thereby further reducing the risk of fistula or bleeding on the first anastomotic surface 430.

[0092] Furthermore, the third patch 230 , the first patch 210 , and the second patch 220 may be used in combination to reduce the risk of fistula or bleeding at each anastomotic opening and improve the adaptability of the stapler 100 .

[0093] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9In one embodiment, the third patch 230 is annular, and includes a weak connection structure 233 extending along its center line; in S131, specifically including: sleeve the two third patches 230 on the nail anvil 120 and the nail magazine 130 respectively; after S132, the method further includes:

[0094] S133: moving the stapler 100 out to break the weak connection structures 233 of the two third patches 230;

[0095] S134 connects the two third patches 230 at the sides away from the hole 410 to each other to cover the anastomotic opening and the cutting surface 440 .

[0096] Specifically, the third patch 230 includes a first portion 231 and a second portion 232 connected to each other, and two sides of the weak connection structure 233 are respectively connected to the first portion 231 and the second portion 232. The two third patches 230 are sleeved on the anvil 120 and the staple cartridge 130, and the first portions 231 of the two third patches 230 correspond to the closed surfaces of the anvil 120 and the closed surfaces of 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 the hole 410 is anastomosed, the two first portions 231 can be stapled to the two sides of the anastomosed hole 410, and the excess tissue 450 can be cut to form a cutting surface 440, and then the two weak connection structures 233 are broken by removing the stapler 100.

[0097] Among them, part of the excess tissue 450 is cut, so that the second parts 232 of the two third patches 230 can cover the corresponding third anastomotic surfaces, and the side of the second part 232 close to the weak connection structure 233 can be bonded to each other to cover the cut surface 440, so that the closed surface of the hole 410 is blocked while the outer side of the hole 410 is also covered, further reducing the risk of fistula or bleeding at the anastomotic opening of the hole 410.

[0098] In the present application, the first patch 210, the second patch 220 and the third patch 230 are respectively adhered to the corresponding anastomotic openings under corresponding surgical procedures, and the first patch 210, the second patch 220 and the third patch 230 can be combined with each other.

[0099] The problem of a certain proportion of fistula and bleeding at the incision 400 is further reduced, and the reliability and adaptability of the anastomosis device are improved.
