An apparatus comprises a surgical instrument having a cutter and a stapler. The cutter is operable to sever a portion of tissue. The apparatus further comprises a plurality of staples where the stapler is operable to introduce the plurality of staples into tissue to form a staple line. The apparatus further comprises a reinforcement clip. The reinforcement clip is operable to be in selective communication with the staple line. The reinforcement clip comprises a crown, a leg portion, and a teeth portion. In some versions, the leg portion has a width operable to cover the area defined by the staple line. In some versions, the teeth portion is configured to anchor into tissue.

1. An apparatus, comprising: (a) a surgical instrument comprising a cutter and a stapler, wherein the cutter is configured to sever a portion of tissue;(b) a plurality of staples in communication with the stapler, wherein the stapler is configured to introduce the plurality of staples to a severed portion of tissue, wherein the stapler is configured to form a staple line with the plurality of staples; and(c) a reinforcement clip configured to selectively cover the staple line, wherein the reinforcement clip is configured to be applied after the plurality of staples have been introduced to a portion of severed tissue, wherein the reinforcement clip comprises: (i) a crown portion, wherein the crown portion has a pair of opposing ends,(ii) a leg portion extending transversely relative to the crown portion, wherein the leg portion comprises opposing, continuous legs, wherein the legs together define a first gap between each leg at each end of the crown portion, and(iii) teeth portions extending transversely relative to each leg, wherein the teeth portions define a second gap between the teeth portions such that the teeth portions are separated from each other by the second gap,wherein the leg portion has a width operable to cover an area defined by the staple line, wherein the teeth portion is configured to anchor the teeth portion into tissue, wherein the reinforcement clip is configured to cover the staple line and the portion of severed tissue; wherein the leg portion further comprises a pair of opposing legs, wherein the crown portion is positioned between the opposing legs and is configured such that the legs cooperate to compress apposed layers of tissue against each other, wherein the reinforcement clip is configured to only partially envelop tissue;wherein the clip comprises a plurality of transversely formed notches spaced apart along the length thereof, wherein each of the notches extends along a portion of each of the legs and the crown. 2. The apparatus of claim 1, wherein the crown portion comprises a living hinge. 3. The apparatus of claim 2, wherein the crown portion further comprises at least one locking feature operable to lock the living hinge, thereby fixing the living hinge in a predetermined position. 4. The apparatus of claim 3, wherein the at least one locking feature comprises at least one clasp. 5. The apparatus of claim 2, wherein the living hinge comprises a ratcheting feature, wherein the ratcheting feature is configured such that the living hinge is moveable in only one direction. 6. The apparatus of claim 1, wherein the reinforcement clip comprises an absorptive material. 7. The apparatus of claim 6, wherein the absorptive material comprises polydioxanone. 8. The apparatus of claim 1, wherein the reinforcement clip is configured to form a seal around a severed portion of tissue. 9. The apparatus of claim 1, wherein the reinforcement clip comprises an elongated C-shaped cross section. 10. The apparatus of claim 1, wherein the reinforcement clip comprises a deformable material. 11. The apparatus of claim 1, wherein the surgical instrument is configured to be actuated to introduce the staples using the stapler into a portion of tissue, wherein the reinforcement clip is configured to cover all of the staples introduced in a single actuation. 12. The apparatus of claim 1, further comprising an applier instrument, wherein the applier instrument is configured to clamp the reinforcement clip over the staple line. 13. The apparatus of claim 12, wherein the applier instrument is further configured to clamp with sufficient force so as to squeeze and secure the staple line. 14. The apparatus of claim 1, wherein the reinforcement clip comprises an inner portion and an outer portion, wherein the inner portion is positionable around a portion of severed tissue, wherein the teeth portion of the reinforcement clip is configured to clamp with sufficient force such that the inner portion remains mechanically isolated from the outer portion. 15. The apparatus of claim 1, wherein the reinforcement clip is configured to enclose the staple line without contacting the staple line. 16. An apparatus comprising: (a) a surgical instrument comprising a cutter and a stapler, wherein the cutter is configured to sever a portion of tissue;(b) a plurality of staples in communication with the stapler, wherein the stapler is configured to introduce the plurality of staples to a severed portion of tissue, wherein the stapler is configured to form a staple line with the plurality of staples;(c) a clip comprising: (i) a crown extending along an axis, wherein the crown has a pair of opposing ends,(ii) a pair of opposing, continuous legs extending transversely relative to the axis with a gap between each of the legs on each end of the crown, wherein the crown and the legs form a generally C-shaped portion, in cross-section along a plane that is perpendicular to the axis, of the clip, and(iii) teeth positioned at the end of each of the opposing legs, wherein the teeth extend transversely from a respective opposing leg of the C-shaped portion and are oriented towards each other,wherein the clip is configured to enclose a staple line, wherein the legs of the clip comprise a width sufficiently wide to overlay the width of the staple line, wherein the teeth are configured to anchor opposing portions of apposed layers of tissue, wherein the reinforcement clip is configured to only partially envelop tissue, wherein the crown comprises a deformable material;wherein the clip comprises a plurality of transversely formed notches spaced apart along the length thereof, wherein each of the notches extends along a portion of each of the continuous legs and the crown; and(d) a surgical applier, wherein the applier is in selective communication with the clip, wherein the applier is configured to deliver the clip to a surgical site, wherein the applier is further configured to clamp the clip, thereby anchoring the clip, wherein the applier is further configured to clamp the clip over the staple line. 17. The apparatus of claim 16, wherein the crown comprises a living hinge and a locking feature, wherein the living hinge is operable to enable the legs to be moveable, wherein the locking feature is configured to selectively prevent the living hinge from moving. 18. The apparatus of claim 17, wherein the locking feature comprises a barb positionable over the living hinge. 19. The apparatus of claim 16, wherein the clip comprises an absorptive material configured to be absorbed over time. 20. An apparatus comprising: (a) a clip comprising: (i) a crown, wherein the crown has a pair of opposing ends,(ii) opposing, first and second continuous legs extending transversely relative to the crown with a gap between the legs on each end of the crown, and(iii) a clamping region, wherein the legs of the clip comprise a width sufficiently wide to overlay the width of the staple line,wherein the clip is configured to only partially envelop tissue, wherein the clamping region is configured to anchor tissue, wherein the crown comprises a deformable material, wherein the clip comprises a plurality of transversely formed notches spaced apart along the length thereof, wherein each of the notches extends along a portion of the first continuous leg, the crown, and a portion of the second continuous leg; and(b) a surgical applier, wherein the applier is in selective communication with the clip, wherein the applier is configured to deliver the clip to a surgical site, wherein the applier is further configured to clamp the clip, thereby anchoring the clip, wherein the applier is further configured to clamp the clip over a staple line.
