Abstract

An exemplary surgical method of treating tissue within the body of a patient may include having an endocutter having an end effector; inserting the end effector into the body of a patient through an opening; engaging tissue with the end effector; stapling tissue along two staple lines with the end effector; cutting tissue between the staple lines with the end effector; releasing the tissue from the end effector; and repeating the engaging, stapling, cutting and releasing within the body of the patient on tissue at a different location within the body of the patient while maintaining the end effector within the body of the patient. Another exemplary surgical method of treating a plurality of discrete tissue structures within the body of a patient in which an incision has been made may include having an endocutter that holds a plurality of staples; inserting the distal end of the endocutter through the incision in the patient; and transecting a plurality of the discrete tissue structures with the distal end of the endocutter, without withdrawing the distal end of the endocutter through the incision in the patient and without inserting additional staples into the endocutter.

Claims (34)

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

having an endocutter having an end effector;

inserting said end effector into the body of a patient through an opening;

engaging tissue with said end effector;

stapling tissue along two staple lines with said end effector;

cutting tissue between the staple lines with said end effector;

releasing the tissue from said end effector; and

repeating said engaging, stapling, cutting and releasing within the body of the patient on tissue at a different location within the body of the patient while maintaining said end effector within the body of the patient.

2. The surgical method of claim 1 , wherein said opening is no greater than 10 millimeters in diameter.

3. The surgical method of claim 1 , wherein said opening is no greater than 10 millimeters in diameter.

4. The surgical method of claim 1 wherein the length of said staple lines is selectable.

5. The surgical method of claim 1 , wherein said end effector includes a knife; wherein said cutting is performed by moving said knife upward and then proximally.

6. The surgical method of claim 1 , wherein said stapling comprises deploying a plurality of staples in each said staple line.

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

having an endocutter having an end effector, the end effector comprising at least one feeder belt movable relative thereto; said feeder belt including a plurality of staples frangibly connected thereto;

placing said end effector adjacent to tissue;

deforming a plurality of said staples into tissue;

separating at least one said deformed staple from said feeder belt;

advancing said feeder belt; and

repeating said placing, deploying and separating.

8. The surgical method of claim 7 , wherein said end effector includes a nose defined therein around which said feeder belt is routed; and wherein said moving includes advancing said feeder belt about said nose.

9. The surgical method of claim 7 , further comprising clamping said feeder belt before said deforming and unclamping said feeder belt before said advancing.

10. The surgical method of claim 7 , further comprising providing feedback from said end effector as to the location of said feeder belt, wherein said advancing is performed based on said feedback.

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

having an endocutter comprising an end effector, comprising

at least one wedge fixed in place therein, and

a feeder belt movable relative to said fixed wedge, said feeder belt including a plurality of staples frangibly connected thereto;

placing said end effector adjacent to tissue to be stapled; and

moving said feeder belt relative to said fixed wedge, wherein said motion causes the distalmost said staple aligned with said fixed wedge to encounter said fixed wedge, deform, and separate from said feeder belt.

12. The surgical method of claim 11 , wherein said moving comprises moving said feeder belt to cause a plurality of said staples generally aligned with said fixed wedge to sequentially encounter said fixed wedge, while maintaining said end effector within the body of the patient.

13. A surgical method of treating a plurality of discrete tissue structures within the body of a patient in which an incision has been made, comprising:

having an endocutter that holds a plurality of staples;

inserting the distal end of said endocutter through the incision in the patient; and

transecting a plurality of the discrete tissue structures with the distal end of said endocutter, without withdrawing the distal end of said endocutter through the incision in the patient and without inserting additional staples into said endocutter.
