A
hernia patch, comprising a central rectangular part, a semi-circular part A, a semi-circular part B, the
diameter of the semi-circular part A coincides with one end of the rectangular part, and the
diameter of the semi-circular part B coincides with one end of the rectangular part. The
hernia patch can be a mesh structure. The periphery of the
hernia patch can comprise a
peripheral collar part connected to the edge of the mesh structure. The
peripheral collar part can be heat-welded to the periphery of the hernia patch. The central rectangular part can comprise a
reference window area in the middle, and the edge of the
reference window area is more than a set value away from the edge of the hernia patch. The mesh structure of the
reference window area can be different from the mesh structure of other parts of the hernia patch. The reference window area can be heat-welded to the central part of the hernia patch. The hernia patch can be manufactured by injection molding.
