Embodiment 1
[0042] Such as figure 1 , 2 , 3, and 4, a double-layer hernia patch is composed of an inner patch 1 and an outer patch 2, and a magnet 3 is set on the outer patch 2.
[0043] Preferably: the number of the magnet 3 is more than one. The specific number can be set to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 15, 16, 18, 20.
[0044] Preferably: the magnet 3 is a sheet, and the two sides of the sheet are respectively two poles. A plurality of magnets are set so that the magnetic poles in the same direction are the same among different magnets.
[0045] Preferably: the magnet 3 can be fixedly installed on the outer layer patch 2 through integral molding, or can be installed and arranged according to operation needs through buckling and other methods.
[0046] Preferably: the inner layer patch 1 and the outer layer patch 2 can be one of non-absorbable synthetic mesh, in vivo absorbable artificial mesh patch, biological tissue extraction engineering scaffold or a combination thereof. ...
Embodiment 2
[0048] On the basis of Embodiment 1, both the inner patch 1 and the outer patch 2 are grid-shaped. Further, the meshes are uniformly distributed.
[0049] Preferably: the grid of the outer patch 2 is larger than the grid of the inner patch 1 .
Embodiment 3
[0051] Such as figure 2 or image 3 As shown, on the basis of Embodiment 1 or Embodiment 2, the magnet 3 is arranged at the grid intersection of the outer patch 2 .

Abstract
The invention discloses a double-layer hernia repairing piece which consists of an inner-layer repairing piece and an outer-layer repairing piece, wherein magnets are arranged on the outer-layer repairing piece; the number of the magnets is more than one; the magnets are of different sizes and are arranged in different ways to meet different requirements. According to the double-layer hernia repairing piece disclosed by the invention, the inner-layer repairing piece has pull force, the outer-layer repairing piece has magnetic force, pressure of an organ is resisted by coactions of the two components, on one hand, as the outer-layer repairing piece has the magnetic force, the repairing piece has large counteraction force at a weakest part, then suture requirements in operation are smartly reduced, and the requirement on the strength of a repairing piece material is reduced.
Description
technical field [0001] The invention belongs to the field of implant medical devices and relates to a double-layer hernia patch. Background technique [0002] A hernia means that an organ leaves its original location and enters another location through a weak point or defect or hole in the human body. The most common site for hernias is the abdomen. Abdominal external hernia refers to the protruding of abdominal viscera to the body surface through congenital or acquired defects or weak areas of the abdominal wall, forming a local mass. [0003] The introduction of polymer mesh structure in hernia mesh suturing surgery has been proven to reduce the recurrence rate and pain, thereby improving the healing effect of patients. The implantation of the mesh into the human body makes the operation a tension-free repair, and the importance of the mesh makes the mesh a key factor in the operation and prognosis. [0004] Currently, the patch is fixed peripherally to body tissue to r...
