The tool assembly is configured to advance the tissue fasteners into the looped member to secure tissue between the fasteners and the looped member.
Claims22
A surgical apparatus for applying tissue fasteners, comprising:
- a handle assembly;
- an elongated body extending from the handle assembly;
- and
- a tool assembly operably mounted on a distal end of the elongate body, the tool assembly including a cartridge assembly for receiving a plurality of fasteners and a housing assembly including a recess for receiving a looped member at least partially therein, wherein the tool assembly is configured to advance the plurality of fasteners into the looped member to secure tissue therebetween, wherein each of the plurality of fasteners includes at least one leg, and wherein no portion of any of the legs of the plurality of fasteners extends completely through the looped member.
A method of securing tissue comprising the steps of:
- providing a surgical apparatus including a cartridge assembly and a housing assembly, wherein the cartridge assembly includes a plurality of fasteners and the housing assembly includes a recess for receiving a looped member at least partially therein, wherein the looped member includes a first lateral surface and a second lateral surface, wherein the plurality of fasteners each include at least one leg extending from a backspan, wherein the portion of each leg that is farthest from the backspan of each of the plurality of fasteners extends through the first lateral surface of the looped member, wherein the portion of each leg that is farthest from the backspan of each of the plurality of fasteners does not extend through the second lateral surface of the looped member;
- positioning tissue to be secured between the cartridge assembly and the housing assembly;
- actuating the surgical apparatus to eject the fasteners through the tissue and into engagement with the looped member, wherein the plurality of fasteners engage the looped member in a loop and hook configuration.
