Patent number: 4895289Abstract: A stapler system for surgical suturing comprising a novel stapler and novel precurved staples designed for use with the stapler. Staples stored on a magazine are implanted by a ram mounted for reciprocal movement on the body of the stapler. The ram is moved to firing position by a handle pivotally mounted to the stapler body. As the handle is pivoted, a flat spring coupled to the ram is biased. When the ram reaches its firing position, the handle slips from engagement with the ram, thus permitting the biased spring to drive the ram downward so as to implant a staple into the incised tissue. The legs of the staple enter the tissue along a curved path. During implantation the staple is bent around an anvil causing the legs of the staple to penetrate the tissue along a curved path. Insertion of the staple legs along this curved path draws adjacent portions of incised tissue together.Type: GrantFiled: January 12, 1989Date of Patent: January 23, 1990Assignee: Ophthalmic Ventures Limited PartnershipInventors: William D. Richards, Ernesto E. Blanco
