Abstract

An exemplary surgical method of treating tissue within the body of a patient, may include providing an endocutter having a knife, a staple holder along which the knife is slidable, feeder belts located on each side of the knife, staples having a first size, those staples integral with and breakable from at least one feeder belt, and staples having a second size different from the first size, those staples integral with and breakable from at least one feeder belt; engaging tissue of the patient with the staple holder; deploying at least two staples having a first size; disengaging tissue of the patient from the staple holder; once again engaging tissue of the patient with the same staple holder; and deploying at least two staples having a second size.

Claims

1. A surgical method of treating tissue within the body of a patient, comprising:

providing an endocutter having a knife, a staple holder along which said knife is slidable, a plurality of feeder belts located on each side of said knife, a first plurality of staples having a first size, said first plurality of staples integral with and breakable from at least one said feeder belt, and a second plurality of staples having a second size different from said first size, said second plurality of staples integral with and breakable from at least one said feeder belt;

engaging tissue of the patient with said staple holder;

deploying at least two of said first plurality of said staples having a first size;

disengaging tissue of the patient from said staple holder;

once again engaging tissue of the patient with the same said staple holder; and

deploying at least two of said second plurality of said staples having a second size.

2. The surgical method of claim 1, wherein said engaging, at least two of said first plurality of said staples having a first size, disengaging, once again engaging, and deploying at least two of said second plurality of said staples having a second size are performed while said staple holder is within the body of the patient, without removing said staple holder from the body of the patient.

3. The surgical method of claim 1, wherein said deploying at least two of said second plurality of said staples having a second size is performed without user input as to the size of the staples.

4. The surgical method of claim 1, wherein said deploying at least two of said second plurality of said staples having a second size is performed by advancing at least one said feeder belt longitudinally relative to the position of said feeder belt during said deploying at least two of said first plurality of said staples having a first size.

5. The surgical method of claim 1, wherein said deploying at least two of said first plurality of said staples having a first size is performed by firing a plurality of said staples connected to a first said feeder belt, and said deploying at least two of said second plurality of said staples having a second size is performed by firing a plurality of said staples connected to a second said feeder belt positioned laterally to said first feeder belt.

6. A surgical method of treating tissue within the body of a patient, comprising:

clamping tissue with a surgical stapler, said surgical stapler including at least one feeder belt to which a plurality of staples of different sized are frangibly affixed;

bending a first plurality of staples having a first size out of said surgical stapler and into tissue;

shearing said first plurality of staples from at least one said feeder belt;

unclamping the tissue;

once again clamping tissue with the same said surgical stapler;

bending a second plurality of staples having a second size out of said surgical stapler and into tissue, wherein said second size is different from said first size;

shearing said second plurality of staples from at least one said feeder belt; and

unclamping the tissue.

7. The surgical method of claim 6, further comprising placing a trocar port in the patient;

inserting said surgical stapler through said trocar port before any said clamping, performing all of the actions of claim 6, and only after completing all of the actions of claim 6 withdrawing said surgical stapler through said trocar port.

8. The surgical method of claim 7, wherein said trocar port is placed between two adjacent ribs of the patient.

9. The surgical method of claim 6, further comprising making an incision in the patient;

inserting said surgical stapler through the incision before any said clamping, performing all of the actions of claim 6, and only after completing all of the actions of claim 6 withdrawing said surgical stapler through the incision.

10. The surgical method of claim 6, wherein at least one of said clamping actions is performed on stomach tissue.
