Buttress brachytherapy and integrated staple line markers for margin identification
A surgical buttress for use in a surgical stapling apparatus is provided. The surgical buttress includes an elongate rectangular body portion defining a width; a nose portion integrally formed with and extending from a distal end of the body portion, the nose portion defining a width that is less than the width of the body portion; a neck portion integrally formed with and extending from a distal end of the nose portion, the neck portion defining a width; a head portion integrally formed with and connected to a distal end of the neck portion, the head portion defining a width; and a tail portion integrally formed with and extending from a proximal end of the body portion, the tail portion defining a width that is less that the width of the body portion. The surgical buttress is formed from a material having filaments. The surgical buttress include radioactive material.
1. A surgical buttress for use in a surgical stapling apparatus, the surgical buttress comprising a body portion and lateral sides extending from opposed edges of the body portion, each of the lateral sides defining pockets therein and each of the pockets having a width extending from the edge of the body portion to an outer edge of the lateral side and including an opening into an internal cavity.
2. The surgical buttress according to claim 1 , wherein the body portion includes biocompatible and bioabsorbable materials.
3. The surgical buttress according to claim 1 , further comprising a radioactive material disposed in at least some of the pockets.
4. The surgical buttress according to claim 1 , wherein at least some of the pockets of the lateral sides contain a brachytherapy seed.
5. The surgical buttress according to claim 4 , wherein the brachytherapy seed of each pocket includes isotopes selected from the group consisting of cesium and iodine.
6. The surgical buttress according to claim 1 , wherein the pockets of each of the lateral sides are longitudinally aligned along the lateral side.
7. The surgical buttress according to claim 6 , wherein the pockets of each of the lateral sides are disposed immediately adjacent one another.
8. The surgical buttress according to claim 1 , wherein the surgical buttress has a fixed width defined by the distance between the outer edges of the lateral sides.
9. A method of embedding radioactive material into a surgical buttress, comprising:
providing a surgical buttress having a body portion;
providing a template holding a radioactive material;
mating the template to the surgical buttress and creating pores in the body portion of the surgical buttress during mating of the template to the surgical buttress; and
embedding the radioactive material into the pores of the body portion of the surgical buttress.
10. The method of claim 9 , wherein the radioactive material is brachytherapy seeds, and embedding the radioactive material further includes embedding the brachytherapy seeds into the body portion of the surgical buttress.
11. The method of claim 10 , wherein the brachytherapy seeds include at least one of iodine or cesium isotopes.
12. The method of claim 9 , wherein embedding the radioactive material includes disposing the radioactive material on at least 10% of a surface area of the surgical buttress.
13. The method of claim 9 , wherein embedding the radioactive material includes applying the radioactive material to at least one of lateral or outer sides of the surgical buttress.
14. A kit for performing surgical stapling, comprising:
a surgical stapling instrument;
at least one surgical buttress including a body portion and lateral sides extending from opposed edges of the body portion, each of the lateral sides defining pockets therein and each of the pockets having a width extending from the edge of the body portion to an outer edge of the lateral side and including an opening into an internal cavity; and
a package of encapsulated radioactive material.
15. The kit of claim 14 , wherein the surgical stapling instrument is a surgical stapling loading unit.
16. The kit of claim 15 , wherein the loading unit is a removable and replaceable staple cartridge assembly.
17. The kit of claim 16 , wherein the at least one surgical buttress is pre-loaded onto the surgical stapling instrument.
18. The kit of claim 14 , wherein the lateral sides are wings that extend beyond sides of the surgical stapling instrument.
19. The kit of claim 14 , wherein the encapsulated radioactive material is brachytherapy seeds.
20. The kit of claim 19 , wherein the brachytherapy seeds have isotopes of cesium or iodine.
21. The kit of claim 14 , wherein the package has shielding.
22. The kit of claim 14 , wherein the package has a template and the encapsulated radioactive material is attached to the template.
