Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and in particular to a reinforcement patch and an anastomosis device. Background Art

[0002] The application of staplers has greatly promoted the development of modern surgery and minimally invasive surgery, and has milestone significance. Staplers can staple tissues through staples while cutting, and are widely used for cutting, suturing or anastomosis of organ tissues such as the intestines, stomach, lungs, and pancreas. However, the rigid stapling of staples alone cannot completely avoid leakage and bleeding of anastomotic tissues. This is because staples are rigid structures that cannot fully match the flexibility of soft tissues, resulting in leakage and bleeding in the staple holes. In addition, due to differences in soft tissue properties in different regions, some soft tissues, such as lungs, have lower strength and may be at risk of anastomotic tearing. To solve the above problems, the anastomotic reinforcement patch can be used in conjunction with the stapler, so that while the stapler cuts and closes the wound, the reinforcement patch is fixed to the wound, blocking the staple holes and improving the strength of the wound, thereby avoiding leakage and bleeding in the wound.

[0003] The reinforcement patch in the related art must retain a certain width of residual material at the edge of the patch and the backing to ensure the suture strength. The presence of the residual material affects the smoothness of the puncture device in and out. Summary of the invention

[0040] Figure 1 A schematic structural diagram of a reinforcement patch in the related art is shown.

[0041] like Figure 1 As shown, in the related art, the stapler is a device used in medicine to replace manual suturing. The reinforced patch 910 includes: a patch 910, a backing 920 and two sutures 930. The two sutures 930 connect the patch 910 and the backing 920 together, respectively, so that the patch 910 and the backing 920 become a whole, and the two sutures 930 lead out a longer traction section. When in use, the patch 910 is installed on the stapler, and then the front part of the stapler is extended into the body cavity to reach the lesion. The stapler jaws are closed so that the jaws clamp the tissue to be anastomosed. Then the traction section is pulled to completely separate the patch 910 from the backing 920. Since the suture 930 and the backing 920 have a fixed connection point at the front end, the backing 920 is pulled back by the suture 930. Next, the stapler is fired, and the tissue is cut with the stapler to form an anastomosis; the stapler fixes the patch 910 to the anastomosis while forming the anastomosis, and cuts it into two parts. Then the stapler jaws are loosened, and the stapler is withdrawn from the patient's body, and the traction section is continued to be pulled to remove the backing 920. Thus, the operation is completed, and the purpose of the patch 910 repairing the anastomosis is achieved. The reinforcement patch 910 in the related art must retain a certain width of residual material at the edges of the patch 910 and the backing 920 to ensure the suture strength. The presence of the residual material affects the smoothness of the puncture device. In addition, when the stapler assembly is punctured with the reinforcement patch 910, due to the friction between the suture 930 and the body cavity, the traction line is sometimes pulled, causing the traction line to be pulled in advance, causing the suture 930 to be pulled off in advance.

[0042] In order to solve at least one of the above-mentioned technical problems, the present disclosure provides a reinforcement patch 200 and a stapler, wherein the reinforcement patch 200 is used for the stapler, and the reinforcement patch 200 comprises: a backing 100, wherein the backing 100 has a first surface 110 and a second surface 120 in the thickness direction; a patch 200, wherein the patch 200 is disposed on the first surface 110, and the patch 200 and the backing 100 are detachably connected; a suture 300, which is used to connect the backing 100 with the patch 200; wherein the two side edges of the backing 100 in the width direction are folded toward the first surface 110 to form a first folding portion 130; the two side edges of the patch 200 in the width direction are folded toward the second surface 120 to form a second folding portion 210; and the suture 300 is configured to connect the first folding portion 130 with the second folding portion 210. The reinforcement patch 200 must retain a certain width parameter due to the stitch edge to ensure the suture strength. The presence of residual material affects the smoothness of entering and exiting the puncture device. Through the structure disclosed in the present invention, the residual material of the stitch edge of the suture thread 300 can be buried inside, thereby reducing the edge size of the outer contour of the anastomotic reinforcement patch 200, thereby reducing the puncture resistance of the component carrying the anastomotic reinforcement patch 200 in and out of the puncture device.

[0043] The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0044] Figure 2 A schematic structural diagram of a reinforcement patch 200 according to an embodiment of the present disclosure is shown. Figure 3 FIG. 2 is a schematic structural diagram of a reinforcement patch 200 according to another embodiment of the present disclosure. Figure 4 FIG. 2 shows a structural schematic diagram of a reinforcement patch 200 according to another embodiment of the present disclosure. Figure 2 , Figure 3 and Figure 4As shown, according to a specific embodiment of the present disclosure, on the one hand, a reinforcement patch 200 is provided for a stapler, comprising: a backing 100, wherein the backing 100 has a first surface 110 and a second surface 120 in a thickness direction; a patch 200, wherein the patch 200 is arranged on the first surface 110, and the patch 200 and the backing 100 are detachably connected; a suture 300, which is used to connect the backing 100 with the patch 200; wherein the side edges of the backing 100 in the width direction are folded toward the direction of the first surface 110 to form a first folding portion 130; the side edges of the patch 200 in the width direction are folded toward the direction of the second surface 120 to form a second folding portion 210; and the suture 300 is configured to connect the first folding portion 130 with the second folding portion 210. The present disclosure arranges the suture 300 inside between the backing 100 and the patch 200, thereby reducing the edge size of the outer contour of the anastomotic reinforcement patch 200 and reducing the puncture resistance of the assembly carrying the anastomotic reinforcement patch 200 into and out of the puncture device. It also prevents the suture 300 from being pulled off during the puncture process. It should be noted that the backing 100 can be made of an elastic material, and the patch 200 itself is a flexible material, so that the reinforcement patch 200 can be turned inward after sewing.

[0045] Figure 5 FIG. 2 shows a schematic structural diagram of an unfolded reinforcement patch 200 according to an embodiment of the present disclosure. Figure 5As shown, in some embodiments, the backing 100 has a substantially parallel first side 140 and a second side 150, a side close to the first side 140 is folded toward the first surface 110, and a side close to the second side 150 is folded toward the first surface 110; the distance between the fold close to the first side 140 and the first side 140 is a first preset length; the distance between the fold close to the second side 150 and the second side 150 is a second preset length. In an optional embodiment, the patch 200 has a substantially parallel third side 220 and a fourth side 230, a side close to the third side 220 is folded toward the second surface 120, and a side close to the fourth side 230 is folded toward the second surface 120; the distance between the fold close to the third side 220 and the third side 220 is a third preset length; the distance between the fold close to the fourth side 230 and the fourth side 230 is a fourth preset length. In some embodiments, the suture line 300 includes a first suture line 310 and a second suture line 320 that are substantially parallel; the first suture line 310 connects the first folded portion 130 formed by the first side 140 and the second folded portion 210 formed by the third side 220; the second suture line 320 connects the first folded portion 130 formed by the second side 150 and the second folded portion 210 formed by the fourth side 230. In some embodiments, the first suture line 310 is substantially parallel to the fold of the first folded portion 130. In an optional embodiment, the second suture line 320 is substantially parallel to the fold of the second folded portion 210. It should be noted that the first side 140, the second side 150, the third side 220, the fourth side 230, the fold of the first folded portion 130, and the fold of the second folded portion 210 are substantially parallel to each other. The first side 140 , the second side 150 , the third side 220 and the fourth side 230 in the width direction of the patch 200 and the backing 100 are folded to facilitate the connection of the suture line 300 and ensure the suture strength.

[0046] In some embodiments, the first preset length is 5-20% of the length from the first side 140 to the second side 150 when unfolded. In a preferred embodiment, the first preset length is 10% of the length from the first side 140 to the second side 150 when unfolded. In an optional embodiment, the second preset length is 5-20% of the length from the first side 140 to the second side 150 when unfolded. In a preferred embodiment, the second preset length is 10% of the length from the first side 140 to the second side 150 when unfolded. In an optional embodiment, the third preset length is 5-20% of the length from the third side 220 to the fourth side 230 when unfolded. In a preferred embodiment, the third preset length is 10% of the length from the third side 220 to the fourth side 230 when unfolded. In an optional embodiment, the fourth preset length is 5-20% of the length from the third side 220 to the fourth side 230 when unfolded. In a preferred embodiment, the fourth preset length is 10% of the length from the third side 220 to the fourth side 230 when unfolded. By designing the width of the folded portion to be 5-20% of the total width, the suturing strength can be ensured, and the removal of the suture line 300 and the use of the reinforcement patch 200 will not be affected by the first folded portion 130 or the second folded portion 210 being too wide.

[0047] In some embodiments, when the backing 100 is unfolded, the length from the first side 140 to the second side 150 is substantially the same as the length from the third side 220 to the fourth side 230 when the patch 200 is unfolded.

[0048] In some embodiments, the reinforcement patch 200 further includes: a traction line 400, the traction line 400 is sleeved on one end of the suture 300; the traction line 400 is dragged under the action of an external force to drive the suture 300 to fall off, so that the first folding portion 130 is separated from the second folding portion 210, resulting in the patch 200 being separated from the backing 100. In some embodiments, the traction line 400 is sleeved on the first suture 310 and the second suture 320 at the same time, and the traction line 400 is dragged under the action of an external force, so that the first suture 310 and the second suture 320 are separated from the backing 100 at the same time. Specifically, the traction line 400 is pulled under the action of an external force, so that the suture 300 can be separated from the backing 100, and 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 expanded state, the patch 200 and the backing 100 are relatively independent, the anastomotic reinforcement patch 200 is repaired to the patient's affected area, and the backing 100 and the stapler can be pulled out of the patient's body.

[0049] In some embodiments, the reinforcement patch 200 further includes: an end cap 500, the end cap 500 being disposed at one end of the backing 100 away from the traction line 400, and the end cap 500 being configured to cover the reinforcement patch 200 and one end of the stapler. Specifically, at least a portion of the end cap 500 is fixedly connected to the end of the backing 100, and at the same time wraps the stapler and the end of the backing 100 to prevent the end of the stapler from directly contacting human tissue. In an optional embodiment, at least a portion of the suture 300 is connected to the end cap 500 to prevent the stapler from being exposed due to a gap between the end cap 500 and the reinforcement patch 200. The suture 300 enables the end cap 500 and the backing 100 to be detachably connected. The end cap 500 has a single-side opening toward the direction of the traction line 400. 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 in the end cap 500, so as to avoid the stapler from directly contacting human tissue; at the same time, the reinforcing patch 200 is prevented from rolling up due to touching the wall of the body cavity when the stapler works in a narrow space. It should be noted that the use of the reinforcing patch 200 with the end cap 500 is helpful to accurately fix the position of the reinforcing patch 200 and prevent the reinforcing patch 200 from rolling up. For the stapler used for open surgery with more sufficient operating space, the reinforcing patch 200 without the end cap 500 can also be used. This is because for open surgery, the operating space is large, and the anastomotic reinforcement patch 200 with or without the end cap 500 can be used. In some embodiments, at least part of the patch 200 is accommodated inside the end cap 500. Specifically, the patch 200 is disposed on the first surface 110 of the backing 100, and the suture line 300 is used to sew the patch 200 and the backing 100 so that the patch 200 and the backing 100 are detachably connected. An end cap 500 is disposed at the first end of the backing 100 to accommodate at least a portion of the patch 200.

[0050] According to a specific embodiment of the present disclosure, on the other hand, a stapler is provided, the stapler comprising: a reinforcement patch 200 as described in any one of the above embodiments.

[0051] The present disclosure aims to protect a reinforcement patch 200 and a stapler, wherein the reinforcement patch 200 is used for a stapler, and the reinforcement patch 200 comprises: a backing 100, wherein the backing 100 has a first surface 110 and a second surface 120 in a thickness direction; a patch 200, wherein the patch 200 is arranged on the first surface 110, and the patch 200 and the backing 100 are detachably connected; a suture 300, which is used to connect the backing 100 with the patch 200; wherein the side edges of the backing 100 in the width direction are folded toward the first surface 110 to form a first folded portion 130; the side edges of the patch 200 in the width direction are folded toward the second surface 120 to form a second folded portion 210; and the suture 300 is configured to connect the first folded portion 130 with the second folded portion 210. The present invention arranges the suture 300 inside the backing 100 and the patch 200, thereby reducing the edge size of the outer contour of the anastomotic reinforcement patch 200 and reducing the puncture resistance of the assembly carrying the anastomotic reinforcement patch 200 into and out of the puncture device, and preventing the suture 300 from being pulled off during the puncture process.

[0052] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. For the system or device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description.
