Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and more particularly, to a reinforcement patch and a stapler. Background Art

[0002] The application of staplers has greatly promoted the development of modern surgery and minimally invasive surgery, and is of milestone significance. A stapler can staple tissues with staples while cutting, and is widely used for cutting, suturing or anastomosing visceral tissues such as the intestine, stomach, lung, and pancreas. However, simply stapling with rigid staples cannot completely avoid leakage and bleeding of the anastomotic tissue. This is because the staples are of rigid structure and cannot fully match the flexibility of soft tissues, resulting in leakage and bleeding at the staple holes. In addition, due to differences in the properties of soft tissues in different regions, some soft tissues such as the lung have low strength and there may be a risk of anastomotic tear. To solve the above problems, a reinforcement patch for the anastomotic site can be used in combination with a stapler, so that while the stapler cuts and closes the wound surface, the reinforcement patch is fixed to the wound surface to block the staple holes of the staples and improve the strength of the wound surface, thereby avoiding leakage and bleeding of the wound surface.

[0003] When the stapler assembly punctures with the reinforcement patch, sometimes it will pull the traction line, resulting in the traction line being pulled in advance and causing the suture to be pulled off in advance. Summary of the Invention

[0004] The purpose of the present disclosure is to provide a reinforcement patch and a stapler, which can solve at least one of the above-mentioned technical problems. The specific solutions are as follows:

[0005] According to a specific embodiment of the present disclosure, on the one hand, the present disclosure provides a reinforcement patch for a stapler. The reinforcement patch includes: a backing, the backing having a first surface and a second surface in the thickness direction; a patch, the patch being disposed on the first surface, and the patch being detachably connected to the backing; a suture for connecting the backing and the patch; wherein the suture includes a first suture and a second suture that are substantially parallel, and both the first suture and the second suture include a plurality of double-strand wire loops, and the first suture and the second suture are connected by a fixing portion.

[0006] In an alternative embodiment, the suture passes through the patch and the backing multiple times, exposing double-strand wire loops on the first surface of the backing and the patch, and exposing single-strand wires on the second surface of the backing; the double-strand wire loops form a lasso structure, and the lasso structure lassos adjacent lasso structures in a first direction; the first direction is the direction from the end of the suture away from the traction line to the end of the suture close to the traction line.

[0007] In an alternative embodiment, at least one of the double-strand sleeves of the first suture extends towards each other with at least one of the double-strand sleeves of the second suture and is designed as a connecting buckle of a slipknot to form the fixing part.

[0008] In an alternative embodiment, at least one of the double-strand sleeves of the first suture is connected to at least one of the double-strand sleeves of the second suture by a first lead wire, and the fixing part is the first lead wire.

[0009] In an alternative embodiment, the reinforcement patch further includes: an end cap, which is arranged at one end of the backing along the opposite direction of the first direction, and the end cap is configured to cover one end of the reinforcement patch and the stapler.

[0010] In an alternative embodiment, the connecting buckle includes: a first rope end, and by dragging the first rope end under an external force, the connecting buckle is driven to be untied.

[0011] In an alternative embodiment, the reinforcement patch further includes: a second lead wire, one end of the second lead wire is connected to the first rope end, and by dragging the other end of the second lead wire under an external force, the first rope end is driven to untie the connecting buckle.

[0012] In an alternative embodiment, at least a part of the patch is received inside the end cap.

[0013] In an alternative embodiment, the reinforcement patch further includes: a traction wire, which is sleeved on the suture at one end in the first direction; when the fixing part is disconnected, by dragging the traction wire under an external force, the suture is driven to be separated from the backing.

[0014] In an alternative embodiment, the traction wire is connected to the second lead wire. When dragging the traction wire under an external force, the traction wire first drives the second lead wire to untie the connecting buckle, and then drives the suture to be separated from the backing.

[0015] In an alternative embodiment, the fixing part is located at one end of the first suture and the second suture close to the traction wire.

[0016] In an alternative embodiment, one end of the first suture and the second suture in the first direction is connected to the traction wire; the double-strand sleeves at one end of the first suture and the second suture in the first direction form the fixing part.

[0017] In an alternative embodiment, the distance between the fixing part and one end of the suture close to the traction wire is a preset distance; the length of the preset distance is 20-50% of the length of the first suture or the second suture.

[0018] In an alternative embodiment, one end of the first suture and the second suture along the first direction is connected to the traction wire; the double-strand sleeve at one end of the first suture along the first direction passes through the repair patch and the backing in the opposite direction of the first direction multiple times; the double-strand sleeve at one end of the second suture along the first direction passes through the repair patch and the backing in the opposite direction of the first direction multiple times, and forms the fixing part with the double-strand sleeve at one end of the first suture along the first direction.

[0019] In an alternative embodiment, at least a part of the connection between the traction wire and the suture is configured as a traction loop, and the traction loop sleeves the suture.

[0020] In an alternative embodiment, the repair patch and the backing have a first state in which at least a part is connected, and a second state in which the repair patch and the backing are relatively independent. When the connection of the double-strand sleeves of the first suture and the second suture is disconnected, an external force acts to drag the traction wire to convert the repair patch and the backing from the first state to the second state.

[0021] According to a specific embodiment of the present disclosure, on the other hand, the present disclosure provides a stapler, including: the reinforced repair patch according to any one of the above technical solutions.

[0022] The above solution of the embodiment of the present disclosure has at least the following beneficial effects compared with the prior art:

[0045] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0051] Figure 1 The structural schematic diagram of the reinforcement patch in the related art is shown.

[0052] As Figure 1As shown, in the related art, a stapler is a device used in medicine to replace manual suturing. The reinforced repair patch includes: a repair patch, a backing, and two suturing threads. The two suturing threads connect the repair patch and the backing together respectively, making the repair patch and the backing an integral whole, and the two suturing threads lead out a relatively long traction section. During use, the repair patch is installed on the stapler, and then the front part of the stapler is inserted into the body cavity to reach the lesion. The stapler jaws are closed to clamp the tissue to be anastomosed. Then the traction section is pulled, so that the repair patch is completely separated from the backing. Since there is a fixed connection point between the suturing thread and the backing at the front end, at this time the backing is pulled backward by the suturing thread. Next, the stapler is fired to cut the tissue by the stapler and form an anastomotic opening; while forming the anastomotic opening, the stapler fixes the repair patch to the anastomotic opening and cuts it into two parts. Then the stapler jaws are loosened, and then the stapler is withdrawn from the patient's body, and the traction section is continuously pulled to take out the backing. Thus, the operation is completed, and the purpose of repairing the anastomotic opening with the repair patch is achieved. When the stapler assembly punctures with the reinforced repair patch, sometimes it will affect the traction thread, resulting in the traction thread being pulled in advance and causing the suturing thread to be pulled off in advance.

[0053] In order to solve at least one of the above-mentioned technical problems, the present disclosure provides a reinforced repair patch and a stapler. The reinforced repair patch is used for a stapler. The reinforced repair patch includes: a backing 100 having a first surface 110 and a second surface 120 in the thickness direction; a repair patch 200 disposed on the first surface 110, and the repair patch 200 is detachably connected to the backing 100; a suturing thread 300 for connecting the backing 100 and the repair patch 200. Wherein, the suturing thread 300 includes a first suturing thread 310 and a second suturing thread 320 that are substantially parallel, and both the first suturing thread 310 and the second suturing thread 320 include a plurality of double-strand sleeves, and the first suturing thread 310 and the second suturing thread 320 are connected by a fixing portion 400. During the use of the reinforced repair patch provided by the present disclosure, the fixing portion 400 needs to be disconnected, and there is no mutual force between the first suturing thread 310 and the second suturing thread 320 before the wound can be sutured. During the puncture process, the suturing thread 300 between the first suturing thread 310 and the second suturing thread 320 cannot be pulled off due to the connection of the fixing portion 400.

[0054] The optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0055] Figure 2 FIG. shows a schematic structural diagram of a reinforced repair patch according to an embodiment of the present disclosure. Figure 3 FIG. shows a schematic structural diagram of a reinforced repair patch according to another embodiment of the present disclosure. Figure 4 FIG. shows a schematic structural diagram of a reinforced repair patch according to still another embodiment of the present disclosure. AsFigure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 , and Figure 4 , according to specific embodiments of the present disclosure, on the one hand, a reinforcement patch for a stapler is provided. The reinforcement patch includes: a backing 100 having a first surface 110 and a second surface 120 in the thickness direction; a patch 200 disposed on the first surface 110, and the patch 200 is detachably connected to the backing 100; a suture 300 disposed on the backing 100 for connecting the backing 100 and the patch 200; the suture 300 passes through the patch 200 and the backing 100 multiple times, and double-stranded wire loops are exposed on the first surface 110 of the backing 100 and the patch 200, and the double-stranded wire loops surround adjacent double-stranded wire loops in a first direction; in some embodiments, one end of the suture 300 is sutured to the backing 100 in a non-detachable manner, so that after the suture 300 is detached, it is still connected to the backing 100, thereby pulling the backing 100 from the body cavity to the outside of the body. If the suture 300 is completely separated from the backing 100, the backing 100 can be taken out of the body through other medical devices, such as medical forceps or clips. Wherein, the suture 300 is divided into a first suture 310 and a second suture 320 that are substantially parallel, and the first suture 310 and the second suture 320 are connected by a fixing portion 400. The reinforcement patch provided by the present disclosure fixedly connects the first suture 310 and the second suture 320 through the fixing portion 400, so that the suture 300 of the first suture 310 and the second suture 320 is fixed, and the traction wire 600 cannot be pulled, preventing the suture 300 from being pulled off during puncture or suturing. It should be noted that the first suture 310 and the second suture 320 are parallel along the first direction; the first direction is the direction from the end of the suture 300 away from the traction wire 600 to the end of the suture 300 close to the traction wire 600.

[0056] Figure 5 FIG. shows a schematic structural diagram of the suture 300 in an embodiment of the present disclosure. As Figure 5 shown, in some embodiments, the suture 300 passes through the patch 200 and the backing 100 multiple times, double-stranded wire loops are exposed on the first surface of the backing and the patch, and single-stranded wires are exposed on the second surface of the backing; the double-stranded wire loops form a noose structure, and the noose structure surrounds adjacent noose structures in a first direction. When the fixing portion 400 is disconnected and the suture 300 is subjected to an external force, the noose structures are gradually pulled apart, and the suture can be removed.

[0057] In some embodiments, the patch 200 and the backing 100 have a first state in which at least a part of them is connected, and a second state in which the patch 200 is relatively independent of the backing 100. When the connection of the double-strand loop of the first suture 310 and the second suture 320 is disconnected, an external force acts on the traction wire 600 to drag the patch 200 and the backing 100 from the first state to the second state. Specifically, when the patch 200 and the backing 100 are in the first state, when an external force acts on the free end of the traction section of the suture 300, the suture 300 disengages from the noose structure, and at the same time, the noose structure of the double-strand loop is disassembled. The connection state of the patch 200 and the backing 100 is changed from the first state to the second state, that is, the backing 100 and the patch 200 are separated. Specifically, when the patch 200 and the backing 100 are in the first state, at least a part of the patch 200 is connected to the backing 100. At this time, the anastomosis reinforcement patch is sleeved on the stapler or at least partially wraps the stapler. When the patch 200 and the backing 100 are in the second state, the patch 200 is relatively independent of the backing 100. The anastomosis reinforcement patch is repaired to the patient's affected area, and the backing 100 and the stapler can be withdrawn from the patient's body.

[0058] Figure 6 FIG. shows a schematic diagram of the formation process of the fixing part 400 according to an embodiment of the present disclosure. As Figure 6 shown, in some embodiments, at least one double-strand loop of the first suture 310 and at least one double-strand loop of the second suture 320 extend towards each other and are designed as a slipknot connecting buckle to form the fixing part 400. In an alternative embodiment, the connecting buckle includes: a first rope end 410. When an external force acts on the first rope end 410, the connecting buckle is driven to be untied. In an alternative embodiment, the reinforcement patch further includes: a second lead wire 800. One end of the second lead wire 800 is connected to the first rope end 410. When an external force acts on the other end of the second lead wire 800, the first rope end 410 is driven to untie the connecting buckle. It should be noted that in the actual use process, when adopting the knotting method as Figure 6 , the knotted part needs to be untied, and tools cannot be used to disconnect the fixing part 400. Figure 7 FIG. shows a schematic diagram of the formation process of the fixing part 400 according to another embodiment of the present disclosure. As Figure 7 shown, in an alternative embodiment, at least one double-strand loop of the first suture 310 is connected to at least one double-strand loop of the second suture 320 through a first lead wire, and the fixing part 400 is the first lead wire. As Figure 6 andFigure 7 As shown, the fixing part 400 can be formed by the double-strand sleeves of the first suture 310 and the second suture 320 extending towards each other and tying a knot; or a section of the first lead wire can pass through the double-strand sleeves of the first suture 310 and the second suture 320 respectively, and then tie a knot to fix the first suture 310 and the second suture 320. At this time, the traction wire 600 cannot be pulled, preventing the suture 300 from being pulled off during puncture or suturing.

[0059] As Figure 2 and Figure 3 As shown, in some embodiments, the reinforcement patch further includes: an end cap 500, which is provided at one end of the backing 100 in the opposite direction of the first direction. The end cap 500 is configured to cover one end of the reinforcement patch and the stapler. Specifically, at least a part of the end cap 500 is fixedly connected to the end of the backing 100, while wrapping the end of the stapler and the backing 100, avoiding the end of the stapler directly contacting human tissue. In an alternative embodiment, at least a part of the suture 300 is connected to the end cap 500 to prevent a gap between the end cap 500 and the reinforcement patch from exposing the stapler. Among them, the suture 300 detachably connects the end cap 500 and the backing 100. The end cap 500 has a single-sided opening in the direction towards the traction wire 600. The end cap 500 is used to accommodate the end of the stapler, so that the end of the stapler abuts against the end cap 500 and is wrapped inside the end cap 500, avoiding the direct contact of the stapler with human tissue; at the same time, when the stapler works in a narrow space, it can prevent the reinforcement patch from curling due to touching the inner cavity wall of the body. It should be noted that using the reinforcement patch with the end cap 500 helps to accurately fix the position of the reinforcement patch and prevent the reinforcement patch from curling. For a stapler used in an open surgery with a more sufficient operating space, a reinforcement patch without the end cap 500 can also be used. This is because for an open surgery, with a large operating space, a reinforcement patch with or without the end cap 500 can be used.

[0060] Figure 8 shows a schematic structural diagram of a reinforcement patch according to another embodiment of the present disclosure. As Figure 8As shown, in some embodiments, a slipknot connection is designed between the double-strand sleeve of the first suture 310 and the second suture 320. The connection includes a first rope end 410. Under the action of an external force, the first rope end 410 is dragged to drive the connection to be untied. In an alternative embodiment, the reinforcement patch further includes: a second lead wire 800. One end of the second lead wire 800 is connected to the first rope end 410. Under the action of an external force, the other end of the second lead wire 800 is dragged to drive the first rope end 410 to untie the connection. It should be noted that in a slipknot, usually pulling one rope end can untie the slipknot, and the first rope end 410 is the rope end that can be untied by pulling. Through the second lead wire 800, the operation end can be led to near the traction wire 600, which is convenient for untying the connection without reaching into the internal buckle of the suture through tools.

[0061] In some embodiments, at least a part of the patch 200 is received inside the end cap 500. Specifically, the patch 200 is disposed on the first surface 110 of the backing 100. The suture 300 is used to sew the patch 200 to the backing 100, so that the patch 200 and the backing 100 are detachably connected. A end cap 500 is provided at the first end of the backing 100 for receiving at least a part of the patch 200.

[0062] Figure 9 The structural schematic diagram of the traction wire and the second lead wire in an embodiment according to the present disclosure is shown. As Figure 9 As shown, in some embodiments, the reinforcement patch further includes: a traction wire 600. The traction wire 600 is sleeved on the suture 300 at one end far from the end cap 500 (the first direction); when the fixing part 400 is disconnected, under the action of an external force, the traction wire 600 is dragged to drive the suture 300 to separate from the backing 100. In an alternative embodiment, the traction wire 600 is connected to the second lead wire 800. When the traction wire 800 is dragged under the action of an external force, the traction wire 800 first drives the second lead wire 800 to untie the connection, and then drives the suture 300 to separate from the backing 100. Specifically, by pulling the traction wire 600 under the action of an external force, the suture 300 can be separated from the backing 100. Further, the end cap 500 is converted from a folded state to an unfolded state, and the patch 200 is separated from the backing 100. At this time, the patch 200 and the end cap 500 are in an unfolded state, the patch 200 and the backing 100 are relatively independent, and the anastomotic orifice reinforcement patch is repaired to the patient's affected area, and the backing 100 and the stapler can be withdrawn from the patient's body.

[0063] In some embodiments, the traction wire 600 is connected to the suture 300. When the fixing part 400 is disconnected, the traction wire 600 is dragged under an external force to separate the lasso structures that are sleeved with each other. In some embodiments, at least a part of the connection between the traction wire 600 and the suture 300 is configured as a traction loop, and the traction loop is sleeved on the suture 300. It should be noted that when the fixing part 400 is disconnected and the traction wire 600 is pulled, due to the arrangement of the traction loop, the pulling forces on the two sutures 300 are basically the same. This is because when the traction wire 600 is usually pulled, although the traction wires 600 on both sides are pulled simultaneously but each is individually stressed. Since the lengths of the traction wires 600 are different, the disassembly speeds are also different, which easily causes uneven stress on both sides of the patch 200. Through the arrangement of the traction loop, the traction wires 600 on both sides can be stressed simultaneously. Although the disassembly speeds of the traction wires 600 on both sides of the patch 200 are different, the traction wires 600 are sleeved with the traction loop, so that the traction wire 600 on the side with a faster disassembly speed can compensate the traction wire 600 on the side with a slower disassembly speed, thereby realizing that the traction wires 600 are pulled simultaneously and the stress is uniform. Therefore, when the fixing part 400 is disconnected and the traction wire 600 is pulled to drive the suture 300 to separate from the backing 100, the stability of the connection between the patch 200 and the anastomosis can be ensured, and the accurate positioning of the reinforcement patch on the stapler can be avoided from being affected due to uneven stress during suture removal.

[0064] Figure 10 FIG. shows a schematic structural view of a fixing part according to another embodiment of the present disclosure. As Figure 10As shown, in some embodiments, the fixing portion is located at one end of the first suture and the second suture close to the traction line. In an alternative embodiment, one end of the first suture 310 and the second suture 320 in the first direction is connected to the traction line 600; the double-strand sleeve at one end of the first suture 310 and the second suture 320 in the first direction forms the fixing portion 400. During actual use, the farther the fixing portion 400 is from the backing 100 in the first direction, the more convenient it is to untie the fixing portion 400 or cut the first lead wire 700. In some other embodiments, the distance between the fixing portion and one end of the suture close to the traction line is a preset distance; the length of the preset distance is 20-50% of the length of the first suture or the second suture. Specifically, the length of the preset distance is 30-40% of the length of the first suture or the second suture. In an alternative embodiment, one end of the first suture 310 and the second suture 320 in the first direction is connected to the traction line 600; the double-strand sleeve at one end of the first suture 310 in the first direction passes through the patch 200 and the backing 100 multiple times in the opposite direction of the first direction; the double-strand sleeve at one end of the second suture 320 in the first direction passes through the patch 200 and the backing 100 multiple times in the opposite direction of the first direction, and forms the fixing portion 400 with the double-strand sleeve at one end of the first suture 310 in the first direction. During actual use, the fixing portion 400 is located at one end of the suture 300 close to the traction line 600 at the preset distance, and leaving the preset distance can prevent the thread end of the fixing portion 400 from being entangled with the traction line 600 and being inconvenient to distinguish. According to a specific embodiment of the present disclosure, on the other hand, a stapler is provided, including: a reinforced patch as described in any one of the above embodiments.

[0065] The present disclosure aims to protect a reinforcement patch and a stapler. The reinforcement patch is used for the stapler and includes: a backing 100 having a first surface 110 and a second surface 120 in the thickness direction; a patch 200 disposed on the first surface 110, and the patch 200 is detachably connected to the backing 100; a suture 300 disposed on the backing 100 for connecting the backing 100 and the patch 200, and the suture 300 is arranged as a closed loop on the backing 100; the suture 300 passes through the patch 200 and the backing 100 multiple times, and double-strand loops are exposed on the first surface 110 of the backing 100 and the patch 200, and the double-strand loops surround adjacent double-strand loops in a first direction; wherein, the suture 300 is divided into a first suture 310 and a second suture 320 that are substantially parallel, and the first suture 310 and the second suture 320 are connected by a fixing portion 400. During the use of the reinforcement patch provided by the present disclosure, the fixing portion 400 needs to be disconnected, and there is no mutual force between the first suture 310 and the second suture 320 before the wound can be sutured. During the puncture process, the suture 300 between the first suture 310 and the second suture 320 cannot be pulled off due to the connection of the fixing portion 400. The reinforcement patch provided by the present disclosure fixedly connects the first suture 310 and the second suture 320 through the fixing portion 400, so that the suture 300 of the first suture 310 and the second suture 320 is fixed, and the traction line 600 cannot be pulled, preventing the suture 300 from being pulled off during the puncture or suturing process.
