Abstract
Abstract A clip unit for hernia repair surgery has first and second arms joined at a hinge joint. A latch or hook locks the arms together after they are closed. A mesh material extends around the outside edges of the clip. In use, the clip is placed over a portion of the elevated peritoneum and then closed and locked. The mesh is fixed to the surrounding peritoneum. The clip and surgical method expedites hernia repair surgery and reduces trauma and medical costs.
