Abstract

A surgical device includes a forceps and a blade. The forceps includes a first working jaw and a second working jaw. The blade extends along a longitudinal axis and includes a notched section. The blade is located between the first working jaw and the second working jaw. A first therapy current can be connected to the first working jaw, the second working jaw, or both so that tissue gripped between the first working jaw and the second working jaw and within the notched section can be coagulated. While the tissue is gripped between the first working jaw and the second working jaw, the blade is moveable along its longitudinal axis so that the tissue is cut with the notched section without repositioning the first working jaw, the second working jaw, or both.

First claim

The invention claimed is:

1. A surgical device comprising:
a. forceps including:
i. a first working jaw, and
ii. a second working jaw; and

b. a blade extending along a longitudinal axis and located between the first working jaw and the second working jaw, the blade including:
i. a notched section, the notched section comprising a proximal edge and a distal edge, at least one of the proximal edge and the distal edge is linear and generally perpendicular to the longitudinal axis, the notched section comprises an upper edge extending between the proximal edge and the distal edge,

wherein the blade is moveable along the longitudinal axis while tissue is gripped between the first working jaw and the second working jaw so, that the tissue is cut with the proximal edge or the distal edge of the notched section without repositioning the first working jaw, the second working jaw, or both,
wherein the blade is a blade electrode that is configured to deliver a first therapy current,
wherein a distal end of the blade electrode is moveable beyond a distal-most end of the forceps so that that the distal end of the blade electrode functions as an electrosurgical blade,
wherein the blade is rotatable between a first rotated position and a second rotated position, and
wherein in the first rotated position, the upper edge of the notched section faces either the first working jaw or the second working jaw, and in the second rotated position the upper edge of the notched section faces a direction between the first working jaw and the second working jaw.

2. The surgical device of claim 1 , wherein the first working jaw, the second working jaw or both is/are configured to deliver a second therapy current so that the tissue gripped between the first working jaw and the second working jaw and within the notched section can be coagulated with the second therapy current.

3. The surgical device of claim 1 , wherein the first therapy current is a monopolar therapy current.

4. The surgical device of claim 1 , wherein both of the proximal edge and the distal edge are linear and generally perpendicular to the longitudinal axis that the blade moves along.

5. The surgical device of claim 1 , wherein the distal end of the blade electrode is dull.

6. The surgical device of claim 1 , the blade is moveable in a distal direction along the longitudinal axis while the tissue is gripped between the first working jaw and the second working jaw so that the tissue is cut with the proximal edge without repositioning the first working jaw, the second working jaw, or both; and
wherein the blade is moveable in a proximal direction along the longitudinal axis while the tissue is gripped between the first working jaw and the second working jaw so that the tissue is cut with the distal edge without repositioning the first working jaw, the second working jaw, or both.

7. The surgical device of claim 1 , wherein the blade electrode is located inside a blade track that extends in the first working jaw, or the second working jaw, or both, so that the blade electrode is located in-between the first working jaw and the second working jaw.

8. An electrosurgical device comprising:
a. forceps including:
i. a first working jaw, and
ii. a second working jaw; and

b. a blade electrode located inside a blade track that extends in the first working jaw or the second working jaw, or both, so that the blade electrode is located in-between the first working jaw and the second working jaw, the blade electrode including:
i. a notched section having a proximal edge, a distal edge and a receiving region therebetween, the notched section also having an upper edge extending between the proximal edge and the distal edge;

wherein the first working jaw, the second working jaw, or both is/are configured to deliver a first therapy current so that during an application of the first therapy current, tissue located within the receiving region and gripped between the first working jaw and the second working jaw is coagulated,
wherein the blade electrode is moveable so that the tissue located within the receiving region of the notched section is cut with either the proximal edge or the distal edge without repositioning the forceps,
wherein the blade electrode is rotatable between a first rotated position and a second rotated position,
wherein in the first rotated position, the upper edge of the notched section faces the first working jaw or the second working jaw, and in the second rotated position the upper edge of the notched section faces a direction between the first working jaw and the second working jaw, and
wherein the blade electrode is configured to deliver a second therapy current so that during an application of the second therapy current, the blade electrode functions as an electrosurgical blade when at least a portion of the blade electrode extends beyond a distal-most end of the forceps.

9. The electrosurgical device of claim 8 , wherein the blade electrode extends along a longitudinal axis, and the proximal edge, the distal edge, or both extend generally perpendicular to the longitudinal axis, and
wherein the blade electrode is moveable along the longitudinal axis to cut the tissue located within the receiving region of the notched section.

10. The electrosurgical device of claim 8 , wherein the blade electrode is moveable towards a proximal end of the forceps so that the tissue located within the receiving region of the notched section is cut with the distal edge of the notched section, and
wherein the blade electrode is moveable towards the distal end of the forceps so that the tissue located within the receiving region of the notched section is cut with the proximal edge of the notched section.

11. The electrosurgical device of claim 8 , wherein the distal edge faces the proximal edge, and the distal edge is spaced apart in a distal direction from the proximal edge along the longitudinal axis.

12. A device comprising:
a. forceps including:
i. a first working jaw, and
ii. a second working jaw; and

b. a blade extending along a longitudinal axis and located between the first working jaw and the second working jaw, the blade including:
iii. a notched section, the notched section comprising a proximal edge and a distal edge,

wherein the distal edge faces the proximal edge,
wherein the distal edge is spaced apart from the proximal edge in a distal direction along the longitudinal axis,
wherein the first working jaw, the second working jaw, or both is/are configured to deliver a bipolar therapy current so that tissue gripped between the first working jaw and the second working jaw and within the notched section can be coagulated with the bipolar therapy current,
wherein the blade is moveable in a proximal direction along the longitudinal axis while the tissue is gripped between the first working jaw and the second working jaw so that the tissue is cut with the distal edge without repositioning the first working jaw, the second working jaw, or both,
wherein the blade is moveable in a distal direction along the longitudinal axis while the tissue is gripped between the first working jaw and the second working jaw so that the tissue is cut with the proximal edge without repositioning the first working jaw, the second working jaw, or both,
wherein the blade is a blade electrode is configured to deliver a monopolar therapy current,
wherein a distal end of the blade electrode is moveable beyond a distal end of the forceps so that that the distal end of the blade electrode functions as an electrosurgical blade,
wherein the blade is rotatable between a first rotated position and a second rotated position,
