Surgical implant
View Patent ↗A surgical implant for fixing a soft tissue to a bone comprising a staple and a plate. The staple and the plate are positionable on an instrument in such a way that the plate may be manipulated with the instrument to hold the soft tissue against the bone and in such a way that the staple is fixable to the bone with the plate positioned between a bridge of the staple and the soft tissue when legs of the staple are driven through the plate and into the bone.
1. A kit for fixing a soft tissue to a bone of a patient, comprising:
an instrument comprising:
a sleeve having a front end, the sleeve defining an inner channel and having an outer peripheral surface, wherein the inner channel is radially inward of the outer peripheral surface;
an impact rod slideably arranged in the inner channel of the sleeve; and
an impact block that is affixed to the impact rod and slideably arranged on the outer peripheral surface of the sleeve;
at least one staple having a bridge and a plurality of legs extending from the bridge, the bridge having a central opening extending through the bridge such that the staple is positionable on the sleeve of the instrument such that the bridge is spaced apart a distance from the front end of the sleeve and in alignment with the impact block so that impacting the impact rod causes the impact block to contact the bridge of the staple and drive the staple along the sleeve toward the front end of the sleeve; and
at least one plate having an upper side and a lower side, the plate being positionable on the front end of the sleeve so as to be separated from the staple when the staple is positioned on the sleeve prior to contacting the bridge of the staple with the impact block and in such a way that the plate may be manipulated with the instrument to hold the soft tissue against the bone and in such a way that the staple is fixable to the bone with the plate positioned between the bridge of the staple and the soft tissue when the legs of the staple are driven through the plate and into the bone.
2. The kit of claim 1 wherein the plate has a central opening configured to receive the front end of the sleeve.
3. The kit of claim 1 , wherein the staple comprises a material having a tensile strength TS 1 and wherein the plate comprises a material having a tensile strength TS2 which is less than the tensile strength TS1 of the staple so that the legs of the staple can penetrate through the plate.
4. The kit of claim 1 , wherein the upper side of the plate has a recess configured to matingly receive the bridge of the staple with the legs positioned through the plate.
5. The kit of claim 4 , wherein the plate has a central axis orthogonal to the lower side and wherein the plate further comprises one or more channels that are open towards the upper side of the plate and extend across the plate orthogonally to the central axis intersecting the recess of the plate.
6. The kit of claim 4 , wherein the bridge of the staple is substantially square shaped with four corners and wherein one leg extends from each of the corners.
7. The kit of claim 4 , wherein the bridge of the staple is substantially circularly shaped and wherein the staple includes at least four legs extending from the bridge and being equally spaced about the bridge.
8. The kit of claim 1 wherein the plate has a plurality of blind holes alignable with the legs of the staple when the staple and the plate are positioned on the sleeve.
9. The kit of claim 1 wherein the plate has a plurality of perforations alignable with the legs of the staple when the staple and the plate are positioned on the sleeve.
10. The kit of claim 1 , wherein the impact rod has a passageway extending longitudinally therethrough.
