Surgical clamp
View Patent ↗A surgical clamp including a pair of jaws, which may be used to ablate or create lesions in tissue. In an exemplary embodiment, the jaws are movable between an articulated position in which the jaws are separated and not parallel to one another, an opened position in which the jaws are separated and substantially parallel to one another, and a closed position in which the jaws are adjacent and substantially parallel to one another.
1. A method of operating a surgical device that includes a first appendage repositionable with respect to a second appendage using rotating offsets, the method comprising:
reorienting the first appendage with respect to the second appendage from a non-parallel orientation to a parallel orientation that clamps tissue between the first appendage and the second appendage while within a cavity of a mammal, which includes:
pivoting a first rotating offset with respect to the first appendage, and,
pivoting and sliding a second rotating offset with respect to the first appendage.
2. The method of claim 1 , further comprising ablating the tissue between the first appendage and the second appendage subsequent to reorienting the first appendage and the second appendage to the parallel orientation.
3. The method of claim 1 , wherein:
the surgical device further includes a rack;
pivoting the first rotating offset includes repositioning the rack, with respect to the first appendage, to engage and reposition the first rotating offset; and,
pivoting the second rotating offset includes repositioning the rack, with respect to the first appendage, to engage and reposition the second rotating offset.
4. The method of claim 1 , wherein:
the surgical device further includes a first cable;
pivoting the first rotating offset includes repositioning the first cable, with respect to the first appendage, to engage and reposition the first rotating offset; and,
pivoting the second rotating offset includes repositioning the first cable, with respect to the first appendage, to engage and reposition the second rotating offset.
5. The method of claim 1 , wherein:
the surgical device further includes a third rotating offset mounted to the second appendage, and a fourth rotating offset mounted to the second appendage; and,
reorienting the first appendage with respect to the second appendage includes:
pivoting the third rotating offset with respect to the second appendage, and
pivoting and sliding the fourth rotating offset with respect to the second appendage.
6. The method of claim 5 , wherein:
the surgical device further includes a rack;
pivoting the first rotating offset includes repositioning the rack, with respect to the first appendage, to engage and reposition the first rotating offset;
pivoting the second rotating offset includes repositioning the rack, with respect to the first appendage, to engage and reposition the second rotating offset;
pivoting the third rotating offset includes repositioning the rack, with respect to the second appendage, to engage and reposition the third rotating offset; and,
pivoting the fourth rotating offset includes repositioning the rack, with respect to the second appendage, to engage and reposition the fourth rotating offset.
7. The method of claim 6 , further comprising ablating the tissue between the first appendage and the second appendage subsequent to reorienting the first appendage and the second appendage to the parallel orientation.
8. The method of claim 5 , wherein:
the surgical device further includes a first cable and a second cable;
pivoting the first rotating offset includes repositioning the first cable, with respect to the first appendage, to engage and reposition the first rotating offset;
pivoting the second rotating offset includes repositioning the first cable, with respect to the first appendage, to engage and reposition the second rotating offset;
pivoting the third rotating offset includes repositioning the second cable, with respect to the second appendage, to engage and reposition the third rotating offset; and,
pivoting the fourth rotating offset includes repositioning the second cable, with respect to the second appendage, to engage and reposition the fourth rotating offset.
9. The method of claim 8 , further comprising ablating the tissue between the first appendage and the second appendage subsequent to reorienting the first appendage and the second appendage to the parallel orientation.
10. A method of operating a surgical device that includes a first appendage repositionable with respect to a second appendage, the surgical device incorporating rotating offsets, the method comprising:
repositioning the first appendage with respect to the second appendage from a non-parallel orientation to a parallel orientation, while tissue is between the first appendage and the second appendage, while within a cavity of a mammal, which includes repositioning a rack, operatively coupled to a first rotating offset and a second rotating offset, to cause pivoting motion between the first appendage and the first rotating offset, and to cause sliding and pivoting motions between the second appendage and the second rotating offset.
