Abstract

A method of surgery includes grasping tissue between tissue-treating plates of first and second jaw members by moving the first and second jaw members from a spaced-apart position to a first approximated position, energizing the tissue-treating plates to conduct energy through the grasped tissue to treat tissue, and separating grasped and treated tissue by moving the first and second jaw members from the first approximated position to a second approximated position. Moving the first and second jaw members from the first approximated position to the second approximated position laterally shifts the jaw members relative to one another from an aligned orientation, wherein the tissue-treating plates are aligned with one another, to an offset orientation, wherein the tissue-treating plates are offset relative to one another.

First claim

What is claimed is:

1. A method of surgery, comprising:
grasping tissue between tissue-treating plates of first and second jaw members by moving the first and second jaw members from a spaced-apart position to a first approximated position;
energizing the tissue-treating plates of the first and second jaw members for conducting energy through grasped tissue to treat grasped tissue; and
separating grasped and treated tissue by moving the first and second jaw members from the first approximated position to a second approximated position, wherein moving the first and second jaw members from the first approximated position to the second approximated position laterally shifts the jaw members relative to one another from an aligned orientation, wherein the tissue-treating plates are aligned with one another, to an offset orientation, wherein the tissue-treating plates are laterally offset and parallel relative to one another.

2. The method according to claim 1 , wherein grasping tissue includes compressing a movable handle relative to a fixed handle from an initial position to a first compressed position to move the jaw members from the spaced-apart position to the first approximated position and wherein separating grasped and treated tissue includes compressing the movable handle from the first compressed position to a second compressed position to move the jaw members from the first approximated position to the second approximated position.

3. A method of surgery, comprising:
grasping tissue between tissue-treating surfaces of first and second jaw members by moving at least one of the first or second jaw members relative to the other of the first or second jaw members from an aligned, spaced-apart position to an aligned, approximated position;
energizing the tissue-treating surfaces of the first and second jaw members to conduct energy through grasped tissue to treat grasped tissue; and
separating grasped and treated tissue by further approximating and laterally shifting the at least one of the first or second jaw members relative to the other of the first or second jaw members from the aligned, approximated position in which the tissue-treating surfaces are aligned with one another and define a first gap distance therebetween to an offset, further approximated position in which the tissue-treating surfaces are laterally offset and parallel relative to one another and define a second smaller gap distance therebetween.

4. The method according to claim 3 , wherein grasping tissue includes compressing a movable handle relative to a fixed handle from an initial position to a first compressed position to move the jaw members from the aligned, spaced-apart position to the aligned, approximated position.

5. The method according to claim 4 , wherein separating grasped and treated tissue includes compressing the movable handle from the first compressed position to a second compressed position to move the jaw members from the aligned, approximated position to the offset, further approximated position.
