Abstract

A bioprosthesis sealing film strip is attached to a surgical stapler by passing a jaw of the stapler through openings formed in the ends of the strip. Following stapling the strip is released by making a cut from the opening to the edge of the strip. Alternatively, one end of the strip may be releasably secured to pins formed on the jaw.

Claims

1. A sealing strip for sealing staple punctures in soft tissue surgery, comprising:

a) a central elongated area adapted to receive surgical stapler.

b) an extension on each end of said central area, each of said extensions having formed therein a least one opening adapted to allow said strip to be temporarily secured to a jaw of a surgical stapler.

2. The sealing strip of claim 1, in which said opening in at least one of said extensions is large enough for said jaw to pass therethrough.

3. The sealing strip of claim 2, in which said opening in both said extensions is large enough for said jaw to pass therethrough.

4. The sealing strip of claim 1, in which said sealing strip is formed of animal pericardium.

5. The sealing strip of claim 1, in which said opening in one of said extensions is smaller than that in the other.

6. In combination, a surgical stapler having a pair of jaws carrying, respectively rows of staples and an anvil, and an elongated strip mounted on each of said jaws, said sealing strip comprising:

a) a central area of a length substantially equal to the length of said staple rows;

b) an extension on each end of said central area, each of said extensions having formed therein at least one opening arranged to allow said snip to be secured to said jaw.

7. The sealing strip of claim 6, in which said opening in at least one of said extensions is large enough for said jaw to pass therethrough.

8. The scaling strip of claim 6, in which said opening in both said extensions is large enough for said jaw to pass therethrough.

9. The sealing strip of claim 6, in which said sealing strip is formed of animal pericardium.

10. The combination of claim 6, in which at least one of said jaws has pins formed thereon, and one of said extensions has formed therein openings adapted to releasably engage at least one of said pins.

11. The combination of claim 10, in which the other of said extensions of said strip is secured to one of said jaws by passing said jaw through an opening formed in said extension.

12. The combination of claim 6, in which both of said extensions of said strip are secured to one of said jaws by passing said jaw through openings formed in said extensions.

13. The combination of claim 6, in which said jaws have upstanding pins formed thereon, and said openings in said ends of said central area are aligned with, and of slightly smaller diameter than, said pins.

14. A method of releasably securing a sealing strip to a jaw of a surgical stapler arranged to drive rows of staples through said sealing strip, comprising the steps of:

a) providing an elongated planar strip of biocompatible sealing material having a central portion of substantially the same length as said staple rows, and extensions on each end of said central portion, said extensions each having at least one opening formed therein;

b) bending at least one of said extensions out of ;

he plane of said strip into a position substantially perpendicular to said jaw;

c) passing said jaw through said opening;

d) temporarily securing the other of said extensions to said jaw; and

e) following a stapling operation, cutting said at least one of said extensions outwardly of said opening to disengage said strip from said jaw.

15. The method of claim 14, in which said other extension is secured to said jaw by passing said jaw through an opening therein.

16. The method of claim 14, in which said other extension is secured to said jaw by engaging at least one opening in said other extension with a pin formed on said jaw.

17. A sealing strip for sealing staple punctures in soft tissue surgery, comprising:

a) a central flat elongated area adapted to receive surgical staples therethrough;

b) a first extension formed on one end of said central area, said first extension having formed therein at least one opening adapted to allow said strip to be temporarily secured to a jaw of a surgical stapler; and

c) a second extension formed on the other end of said central area, said extension having a cut therein of such extent and shape that, when a said portion of second extension is bent out of the plane of said strip, the bent portion defines an opening adapted to be slipped ova said jaw, while the reminder remains in said plane of said strip to form a flat extension of said central area.
