Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a surgical patch capable of local thickening. Background Art

[0002] Inguinal hernia surgical patches can be divided into biological patches, absorbable patches and non-absorbable patches from the perspective of materials. Biological patches are mainly derived from bovine pericardium and porcine small intestine, absorbable patches are mainly polylactic acid and polyglycolic acid, and non-absorbable patches are mainly polypropylene, polyester and expanded polytetrafluoroethylene; from the perspective of patch morphology, they can be divided into flat patches and preformed patches. The density of surgical patches refers to the quantity and density of suture materials used during surgery. Patches with higher density can provide more structural support and stability, help repair damaged tissues, and prevent the surgical area from being damaged again. At the same time, proper adjustment of patch density can affect the healing speed and quality of wounds. In actual operation, since the patch is fixed to the human tissue on the periphery, the strength and density of the peripheral material of the patch are both required to be high. Most of the existing patches are single-layer structures. The peripheral density of the patch is increased by shearing and superposition during surgery, which makes the surgical operation complicated and difficult, and it is easy to cause uneven force on the patch and deformation.

[0003] In order to solve the above technical problems, Chinese patent CN109589185B discloses a double-layer hernia patch, which is composed of an inner patch and an outer patch, and a magnet is arranged on the outer patch. The number of magnets is more than one, and the size and arrangement of the magnets meet different requirements. The inner patch of the above patent resists the pressure of internal organs through tension, and the outer patch resists the pressure of internal organs through magnetic force. The outer patch introduces magnetic force, which changes the passive situation of the overall force of the patch, so that the patch forms a larger reaction force at the weakest point, cleverly reducing the suturing requirements during surgery and reducing the strength requirements of the patch material. However, for the periphery of the patch that needs to be sutured, the above patent does not make improvements on the structure of the patch itself, but increases the cost by adding other components, which has problems such as high difficulty in operation.

[0004] Therefore, it is necessary for those skilled in the art to provide a surgical patch that can be locally thickened, selectively enhance the peripheral structure of the patch, and specifically improve the use effect of the patch. Utility Model Content

[0005] The utility model aims to provide a surgical patch that can be locally thickened, so as to solve the technical problem that most of the patches in the prior art are of single-layer structure, and the density of the sutured parts on the periphery of the patch is low, which easily leads to uneven force on the patch and deformation.

[0006] The utility model adopts the following technical scheme to solve the technical problem: a surgical patch capable of local thickening, comprising a patch body and a first auxiliary patch and a second auxiliary patch arranged around the patch body, wherein four first auxiliary patches are provided and are respectively located at the four corners of the patch body, four second auxiliary patches are provided and are respectively located at the four sides of the patch body, and one second auxiliary patch is located between two first auxiliary patches; the first auxiliary patch and the second auxiliary patch are rotatably provided on the patch body, large-diameter through holes are uniformly provided on the patch body, first small through holes are uniformly provided on the first auxiliary patch, and second small through holes are uniformly provided on the second auxiliary patch; the areas of a first small through hole and a second small through hole are consistent, and at the same time, the area of ​​a first small through hole is smaller than the area of ​​a large-diameter through hole.

[0007] Furthermore, a connecting ring is provided on the patch body, the connecting ring is in an annular structure and is provided in plurality, one end of the connecting ring is connected to the patch body, and the other end of the connecting ring is connected to the first auxiliary patch and the second auxiliary patch.

[0008] Further, the long side of the second secondary patch abuts against the patch body, and the second secondary patch is rotatably arranged on the patch body around the long side abutting against the patch body.

[0009] Furthermore, one end of the connecting ring is connected to the patch body, and the other end of part of the connecting ring is connected to the second auxiliary patch.

[0010] Furthermore, one side edge of the first auxiliary patch abuts against the patch body, one end of the connecting ring is connected to the patch body, and the other end of a part of the connecting ring is connected to the first auxiliary patch.

[0011] Furthermore, the connecting ring is made of polylactic acid.

[0012] Furthermore, the first secondary patch and the second secondary patch are both made of polyglycolic acid.

[0013] Furthermore, the large-diameter through hole, the first small through hole and the second small through hole are all in a square hole structure, and the area of ​​the first small through hole is half of the area of ​​the large-diameter through hole.

[0014] Furthermore, the large-diameter through hole, the first small through hole and the second small through hole are all in the shape of circular holes, and the diameter of the first small through hole is half of the diameter of the large-diameter through hole.

[0022] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0023] See also Figure 1 , Figure 2 The utility model provides a surgical patch that can be locally thickened, including a patch body 10 and a first auxiliary patch 11 and a second auxiliary patch 12 arranged around the patch body 10. The patch body 10 is a rectangular structure, four first auxiliary patches 11 are provided and are respectively located at the four corners of the patch body 10, four second auxiliary patches 12 are provided and are respectively located at the four sides of the patch body 10, and one second auxiliary patch 12 is located between two first auxiliary patches 11.

[0024] For further information, see Figure 3 , Figure 4 and Figure 5 , the first auxiliary patch 11 and the second auxiliary patch 12 are rotatably arranged on the patch body 10, the patch body 10 is uniformly provided with large-diameter through holes 13, the first auxiliary patch 11 is uniformly provided with first small through holes 14, and the second auxiliary patch 12 is uniformly provided with second small through holes 15. The areas of a first small through hole 14 and a second small through hole 15 are the same, and the area of ​​a first small through hole 14 is smaller than the area of ​​a large-diameter through hole 13. Therefore, within a unit area, the number of the first small through holes 14 and the second small through holes 15 on the first auxiliary patch 11 and the second auxiliary patch 12 is greater than the number of the large-diameter through holes 13 on the patch body 10, so that within a unit area, the structural density of the first auxiliary patch 11 and the second auxiliary patch 12 is greater than the structural density of the patch body 10.

[0025] The utility model provides a surgical patch with different density structures by adding a first auxiliary patch 11 and a second auxiliary patch 12 and improving the density of the first auxiliary patch 11 and the second auxiliary patch 12. The first auxiliary patch 11 and the second auxiliary patch 12 are arranged around the patch body 10. The high density of the first auxiliary patch 11 and the second auxiliary patch 12 is used to improve the structural strength and structural density around the patch body 10, provide more structural support for the operation, ensure the stability of the suture between the patch body 10 and the human body around the patch body 10 during suturing, and thus effectively prevent the surgical area from being damaged again. At the same time, the high-density area formed by the patch body 10 and the first auxiliary patch 11 and the second auxiliary patch 12 located around it can improve the healing speed and quality of the sutured part.

[0026] In this embodiment, the large-diameter through hole 13, the first small through hole 14 and the second small through hole 15 are all in a square hole structure, and the area of ​​the first small through hole 14 is half of the area of ​​the large-diameter through hole 13. In this way, when the first auxiliary patch 11 and the second auxiliary patch 12 are installed on the periphery of the patch body 10, the first small through hole 14 and the second small through hole 15 will cover the large-diameter through hole 13, thereby making the periphery of the patch body 10 more dense and complex under the addition of the first auxiliary patch 11 and the second auxiliary patch 12, and the large-diameter through hole 13, the first small through hole 14 and the second small through hole 15 interlaced with each other to form a large number of cavities of different shapes and volumes, thereby improving the structural strength and use effect of the surgical patch of the utility model.

[0027] In another embodiment, the large diameter through hole 13, the first small through hole 14 and the second small through hole 15 are all in the shape of circular holes, and the diameter of the first small through hole 14 is half of the diameter of the large diameter through hole 13. In this way, the large diameter through hole 13 and the first small through hole 14 and the second small through hole 15 are arranged in an interlaced manner, thereby ensuring the high density and stability of the edges around the utility model.

[0028] Furthermore, the patch body 10 is provided with a connecting ring 16, which is a ring-shaped structure and is provided in plurality, one end of the connecting ring 16 is connected to the patch body 10, and the other end of the connecting ring 16 is connected to the first auxiliary patch 11 and the second auxiliary patch 12. Preferably, the connecting ring 16 is made of polylactic acid. The first auxiliary patch 11 and the second auxiliary patch 12 are both made of polyglycolic acid.

[0029] Specifically, the long side of the second auxiliary patch 12 abuts against the patch body 10 and the second auxiliary patch 12 is rotatably arranged on the patch body 10 around the long side abutting against the patch body 10, one end of the connecting ring 16 is connected to the patch body 10, and the other end of part of the connecting ring 16 is connected to the second auxiliary patch 12. In this way, the stability of the connection between the patch body 10 and the second auxiliary patch 12 is ensured. During use, when the second auxiliary patch 12 is too long, the second auxiliary patch 12 is manually rotated to make part of the second auxiliary patch 12 separate from the patch body 10 and tilt up, and the operator cuts off part of the second auxiliary patch 12 to make it fit the human body more closely, thereby improving the convenience and stability of the use of the utility model. If the second auxiliary patch 12 needs to be removed as a whole, the operator directly cuts off the connecting ring 16 connected between the patch body 10 and the second auxiliary patch 12, and then removes the second auxiliary patch 12, thereby achieving adaptive selection of the thickness and density around the patch body 10, greatly improving the convenience and scope of use, and ensuring the reliability of operation.

[0030] One side of the first secondary patch 11 abuts against the patch body 10, one end of the connecting ring 16 is connected to the patch body 10, and the other end of the connecting ring 16 is connected to the first secondary patch 11. In this way, the connection stability and convenience of use between the patch body 10 and the first secondary patch 11 are ensured.

[0031] The utility model utilizes polylactic acid as a biodegradable material, and uses it as the main component connecting the patch body 10 with the first auxiliary patch 11 and the second auxiliary patch 12. While increasing the thickness of the patch body 10, the first auxiliary patch 11 and the second auxiliary patch 12 are rotatably arranged on the patch body 10, so as to facilitate the disassembly and shearing of the first auxiliary patch 11 and the second auxiliary patch 12, and effectively improve the use effect of the utility model; at the same time, the degradable first auxiliary patch 11, the second auxiliary patch 12 and the connecting ring 16 ensure the convenience and reliability of operation, and the operator does not need to worry about the omission of debris, which greatly reduces the surgical risk and the difficulty of operation, and improves the use stability of the utility model.

[0032] The specific operation method of the utility model is: a first auxiliary patch 11 and a second auxiliary patch 12 are rotatably arranged on a patch body 10, the patch body 10 is placed into a human body, the size and shape of the first auxiliary patch 11 and the second auxiliary patch 12 are adjusted, and then the patch body 10 and the first auxiliary patch 11 and the second auxiliary patch 12 thereon are sutured together into the wound to complete hernia repair.

[0033] The utility model utilizes polylactic acid as a biodegradable material, and uses it as the main component connecting the patch body 10 with the first auxiliary patch 11 and the second auxiliary patch 12. While increasing the thickness of the patch body 10, the first auxiliary patch 11 and the second auxiliary patch 12 are rotatably arranged on the patch body 10, so as to facilitate the disassembly and shearing of the first auxiliary patch 11 and the second auxiliary patch 12, and effectively improve the use effect of the utility model; at the same time, the utility model can realize the adaptive selection of the thickness and density around the patch body 10, which greatly improves the convenience and scope of use, and ensures the reliability of operation.
