Description

Technical Field

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

[0002] Stapler is a medical device that replaces manual suturing. Figure 1 As shown, the reinforced patch comprises a patch 1, a backing 2, and two sutures 3. The two sutures connect the patch and backing, forming a single unit. The two sutures extend into a long traction section. During use, the reinforced patch is mounted on a stapler, which is then mounted on a puncture device. After puncturing the patient, the stapler is used to secure the patch to the anastomotic stoma. The traction section is then pulled outward from the patient's body to detach the backing from the patch, completing the anastomotic repair with the patch 1.

[0003] However, since the traction section is too long, it is very easy to get entangled with the anastomosis device or puncture device during the installation process, causing the patch and the backing to separate prematurely or be difficult to separate, and the normal repair cannot be completed.

[0004] Therefore, the present disclosure provides a reinforcement patch for an anastomosis to solve one of the above technical problems. Summary of the Invention

[0032] It should be noted in particular that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0033] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0034] The present disclosure provides an embodiment of a reinforcement patch for an anastomotic stoma.

[0035] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0036] An embodiment of the present disclosure provides a reinforcement patch for an anastomosis, comprising: a patch, a backing, and a suture; the backing comprises a lining tongue extending from a first edge of the patch, the suture comprises a suture segment and a traction segment connected to the suture segment, the patch and the backing are detachably connected via the suture segment of the suture, the traction segment of the suture has a fixed state housed in the lining tongue, and has a state ready to be pulled away from the lining tongue.

[0037] In some specific embodiments, Figure 2 As shown, the suture includes a suture, both ends of the suture are set as suture segments, and the middle segment of the suture segment is set as the traction segment of the suture.

[0038] This embodiment uses a suture thread, with both ends of the suture thread serving as suture segments to detachably connect the patch and the backing, and a mid-section of the suture thread forming a semi-circular traction segment, thereby reducing the possibility of the traction segment breaking and ensuring its reliability.

[0039] In other specific embodiments, Figure 3 As shown, the suture includes at least two sutures, and the free ends of the pulling sections of the at least two sutures are fixedly connected.

[0040] The fixed connection includes a knotted connection and / or an adhesive connection. In this specific embodiment, the free ends of the at least two sutures are connected together by a fixed connection, thereby preventing the free ends of the at least two sutures from loosening during installation, forming two independent traction segments, and becoming entangled with the anastomosis device and / or puncture device, thereby ensuring that the operation can be successfully completed.

[0041] The traction segment of the suture thread described in the embodiment of the present disclosure has a fixed state in which it is housed in the lining tongue of the backing, and a state in which it is ready to be pulled in which it is separated from the lining tongue. When the reinforcement patch is installed on the anastomosis device, or the anastomosis device equipped with the reinforcement patch is installed on the puncture device, the traction segment is housed in the lining tongue, so that the traction segment is in a fixed state. After the patch is repaired to the anastomosis using the anastomosis device, the traction segment is taken out from the lining tongue, so that the traction segment is in a state in which it is ready to be pulled, and the traction segment is pulled outward to separate the backing from the patch, and the backing is pulled out from the patient's body. This avoids the entanglement of the traction segment with the anastomosis device and / or the puncture device during the installation process, which causes the patch and the backing to separate prematurely or with difficulty, and makes it impossible to complete the normal repair. The smoothness, reliability and safety of the operation are ensured, and the success rate of the operation is improved.

[0042] In some specific embodiments, the lining tongue includes a receiving mechanism; when the traction segment is received in the receiving mechanism, the traction segment is in a fixed state; when the traction segment is separated from the receiving mechanism, the traction segment is in a waiting state.

[0043] The storage mechanism includes a storage bag and a binding belt. Of course, the storage mechanism of the embodiment of the present disclosure is not limited thereto.

[0044] The storage bags include concealed storage bags and visible storage bags. A concealed storage bag is one in which only the opening is visible from the outside, while the bag body is hidden within the lining. A visible storage bag is one in which both the opening and the bag body are visible from outside light. A visible storage bag may use one side of the lining as part of the bag body. Of course, the storage bags of the disclosed embodiments are not limited to this.

[0045] The types of tie straps include knotted and quick-connect types. Knotted tie straps secure the traction section by tying a knot. Quick-connect tie straps quickly secure the traction section by using quick-connect mechanisms provided at both ends of the tie strap. Examples of quick-connect mechanisms include Velcro, snaps, and buttons, though the quick-connect tie straps of the disclosed embodiments are not limited thereto.

[0046] In some specific embodiments, Figure 4 As shown, the receiving mechanism is arranged on a side of the lining tongue close to the patch.

[0047] The opening of the storage bag can face any direction, for example, the opening of the storage bag faces the first edge. The opening of the storage bag can also be set at any position of the lining tongue.

[0048] In some specific embodiments, the storage mechanism includes a storage bag, the bag opening of the storage bag faces away from the first edge, so that the traction section in a fixed state passes through the edge of the bag opening and is folded and stored in the storage bag.

[0049] In this embodiment, the opening of the storage bag faces away from the first edge, and the traction section is then folded and secured using the edge of the opening, thereby increasing the stability of the traction section within the storage bag. Optionally, the opening of the storage bag is elastic, and the traction section can be further secured at the edge of the opening, further enhancing the stability and reliability of the traction section within the storage bag.

[0050] In some specific embodiments, the maximum distance from the vertex of the stretched traction segment to the first edge of the patch is less than or equal to twice the length of the lining tongue, and is greater than the distance from the edge of the bag opening of the storage bag to the first edge, and the length of the lining tongue is equal to the distance from the edge of the lining tongue away from the first edge to the first edge.

[0051] This specific embodiment shortens the maximum distance from the stretched vertex of the traction segment to the first edge of the patch, further reducing the possibility of the traction segment being entangled inside and outside the storage bag.

[0052] Optionally, the edge of the bag opening of the storage bag is flush with the edge of the lining tongue away from the first edge, thereby retaining the length of the traction section outside the storage bag to the maximum extent and avoiding excessive traction sections from piling up in the storage bag and causing entanglement.

[0053] In some specific embodiments, Figure 5 As shown, the receiving mechanism is arranged on the side of the lining tongue facing away from the repair piece.

[0054] The opening of the storage bag can face any direction, for example, the opening of the storage bag faces the first edge. The opening of the storage bag can also be set at any position of the lining tongue.

[0055] In some specific embodiments, the storage mechanism includes a storage bag, the bag opening of which faces away from the first edge, so that the traction section in a fixed state is folded through the lining tongue edge away from the first edge and stored in the storage bag.

[0056] In this specific embodiment, the opening of the storage bag faces away from the first edge, that is, the opening of the storage bag faces the edge of the lining tongue away from the first edge. The traction section is stored within the storage bag by wrapping around the edge of the lining tongue away from the first edge. The traction section is folded and secured by the edge of the lining tongue away from the first edge, thereby improving the stability of the traction section within the storage bag. Optionally, the opening of the storage bag is elastic, and the traction section can be further secured to the edge of the opening to enhance its stability within the storage bag.

[0057] In some specific embodiments, the edge of the bag opening of the storage bag is flush with the edge of the lining tongue away from the first edge.

[0058] In this embodiment, the traction section is folded and fixed at the edge of the lining tongue away from the first edge. If the bag opening is elastic, the edge of the bag opening is further used to tighten and fix the traction section, thereby enhancing the stability and reliability of the traction section.

[0059] In some specific embodiments, the maximum distance from the vertex of the stretched traction segment to the first edge of the patch is less than or equal to twice the length of the lining tongue, and greater than the sum of the lining tongue length and the bag opening distance, wherein the lining tongue length is equal to the distance from the lining tongue edge away from the first edge to the first edge, and the bag opening distance is equal to the distance from the bag opening edge of the storage bag to the lining tongue edge away from the first edge.

[0060] This specific embodiment shortens the maximum distance from the stretched vertex of the traction segment to the first edge of the patch, further reducing the possibility of the traction segment being entangled inside and outside the storage bag.

[0061] 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 referenced to each other.

[0062] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
