Abstract

There is provided a penetratable toothed fastener for clamping tissue during surgery. The toothed fastener includes first and second legs each having longitudinal rows of transverse teeth and a securing member configured to pass through the transverse teeth to hold first and second legs closed relative to each other and about tissue. A locking mechanism is provided to retain the securing member within the first and second legs of the toothed fastener. The toothed fastener additionally includes receptacles for the receipt of medicant materials and holes in the teeth to dispense the materials to clamped tissue.

Claims

1. A surgical fastener comprising:

a first toothed member and a second toothed member, wherein the first toothed member includes a plurality of teeth defining spaces therebetween, and the second toothed member includes a plurality of teeth configured to be disposed in at least some of the spaces between the teeth of the first toothed member, wherein a receptacle is defined in at least one tooth of each of the first toothed member and the second toothed member;

a securing member receivable through the first toothed member and the second toothed member; and

a fluid material disposed in the receptacle of the at least one tooth of the first toothed member and the second toothed member.

2. The surgical fastener as recited in claim 1, wherein each tooth includes distal and proximal faces, each tooth having a pair of spaced apart holes formed in each of the distal and proximal faces.

3. The surgical fastener as recited in claim 2, wherein the securing member is a bar having first and second legs for passage through the pair of spaced apart holes.

4. The surgical fastener as recited in claim 3, wherein the securing member includes a backspan and the first and second legs extend distally from the backspan.

5. The surgical fastener as recited in claim 1, wherein at least one of the first toothed member and the second toothed member has a hole formed therein, the hole being sized to engage the securing member in friction fit fashion.

6. The surgical fastener as recited in claim 1, wherein the fluid material is contained within a puncturable capsule.

7. The surgical fastener as recited in claim 1, further comprising a connector connecting the first toothed member to the second toothed member at a first end.

8. The surgical fastener as recited in claim 7, wherein the connector is a living hinge formed integrally with proximal ends of the first toothed member and second toothed member.

9. A surgical instrument comprising:

a first jaw;

a second jaw;

a pusher; and

a surgical fastener, including;

a first toothed member and a second toothed member, the first toothed member and the second toothed member each defining at least one tooth defining a receptacle;

a securing member receivable through the first toothed member and the second toothed member; and

a fluid material disposed in the receptacle of the at least one tooth of the first toothed member and the second toothed member, the first toothed member being supported on the first jaw, the second toothed member being supported on the second jaw, and the pusher being engageable with the securing member to advance the securing member through the first toothed member and the second toothed member.

10. The surgical instrument as recited in claim 9, wherein each tooth of the surgical fastener includes distal and proximal faces, each tooth having a pair of spaced apart holes formed in each of the distal and proximal faces.

11. The surgical instrument as recited in claim 10, wherein the securing member of the surgical fastener is a bar having first and second legs for passage through the pair of spaced apart holes.

12. The surgical instrument as recited in claim 11, wherein the securing member of the surgical fastener includes a backspan and the first and second legs extend distally from the backspan.

13. The surgical instrument as recited in claim 9, wherein at least one of the first toothed member and the second toothed member of the surgical fastener has a hole formed therein, the hole being sized to engage the securing member in friction fit fashion.

14. The surgical instrument as recited in claim 9, wherein the fluid material is contained within a puncturable capsule.

15. The surgical instrument as recited in claim 9, further comprising a connector connecting the first toothed member to the second toothed member at a first end.

16. The surgical instrument as recited in claim 15, wherein the connector is a living hinge formed integrally with proximal ends of the first toothed member and second toothed member.
