1. An apparatus comprising:

(a) a first jaw, wherein the first jaw comprises:

(i) a first grasping surface,

(ii) a first exterior surface facing away from the rest of the first jaw,

(iii) a first electrode surface attached to the first grasping surface, and

(iv) a third electrode surface attached to the first exterior surface;

(b) a second jaw pivotally coupled with the first jaw, wherein the second jaw comprises:

(i) a second grasping surface,

(ii) a second exterior surface facing away from the rest of the second jaw,

(iii) a second electrode surface attached to the second grasping surface, and

(iv) a fourth electrode surface attached to the second exterior surface,

wherein the first jaw and the second jaw are configured to grasp tissue in a closed position, wherein the first electrode surface and the third electrode surface are perpendicular with each other, wherein the second electrode surface and the fourth electrode surface are perpendicular with each other, and wherein the first and second electrode surfaces are laterally and vertically offset from each other;

(c) a first handle in communication with the first jaw; and

(d) a second handle in communication with the second jaw, wherein the first handle and the second handle are operable to drive the first jaw and the second jaw to the closed position.

2. The apparatus of claim 1 , further comprising a power source, wherein the power source is operable to deliver bipolar RF energy to the first and second electrode surfaces.

3. The apparatus of claim 1 , wherein the jaws together define a central longitudinal axis, wherein the jaws are laterally centered along a vertical plane passing through the longitudinal axis, wherein the first and second electrode surfaces are operable to deliver bipolar RF energy to tissue along a path that passes transversely through the longitudinal axis and obliquely through to the vertical plane.

4. The apparatus of claim 1 , wherein the exterior of the first jaw comprises at least one protrusion configured to perform blunt dissections.

5. The apparatus of claim 1 , further comprising a movable cutting member, wherein the movable cutting member is operable to sever tissue clamped between the first and second jaws.

6. The apparatus of claim 5 , further comprising a cutting member lockout feature, wherein the cutting member lockout feature is operable to selectively prevent movement of the cutting member based on an activation state of the first and second electrode surfaces.

7. The apparatus of claim 1 , further comprising a pivoting member operable to restrict movement of the first handle relative to the second handle, wherein the pivoting member is operable to permit movement of the first handle to a partially closed position relative to the second handle when the pivoting member is in a first position, wherein the pivoting member is operable to permit movement of the first handle from the partially closed position to a fully closed position when the pivoting member is in a second position.

8. The apparatus of claim 7 , further comprising an activation button integral with the pivoting member, wherein the activation button is operable to activate the first and second electrode surfaces with bipolar RF energy.

9. An apparatus comprising:

(a) a first jaw, wherein the first jaw includes a first electrode surface;

(b) a second jaw pivotally coupled with the first jaw, wherein the second jaw comprises a second electrode surface;

(c) a knife configured to translate through the first jaw and the second jaw;

(d) a handle portion comprising:

(i) a first arm in communication with the first jaw,

(ii) a second arm in communication with the second jaw, and

(iii) a pivot coupling the first arm and the second arm together, wherein the handle portion is operable to close the first jaw against the second jaw by rotating the first arm and the second arm about the pivot;

(e) a trigger pivotably coupled with the first arm, wherein the trigger is configured to energize the first jaw and the second jaw, wherein the trigger is further configured to advance the knife through the first jaw and the second jaw; and

(f) a lockout feature fixed to the trigger, wherein the lockout feature is located proximal to the pivot, wherein the lockout feature is operable to selectively prevent advancement of the knife based on an energization state of the jaws.

10. The apparatus of claim 9 , wherein the lockout feature comprises a notch associated with the knife, wherein the trigger is spring biased to engage the notch to thereby prevent advancement of the knife.

11. An apparatus comprising:

(a) a first jaw, wherein the first jaw includes a first electrode surface;

(b) a second jaw pivotally coupled with the first jaw, wherein the second jaw comprises a second electrode surface;

(c) a knife configured to translate through the first jaw and the second jaw; and

(d) a handle portion comprising a first arm in communication with the first jaw, and a second arm in communication with the second jaw, wherein the second arm is pivotally coupled to the first arm, wherein the knife is pivotally coupled to the first arm, wherein the second arm is configured to rotate through a first range of motion and a second range of motion, wherein the first range of motion is configured to pivot the second jaw towards the first jaw, wherein the second range of motion is configured to translate the knife through the first jaw and the second jaw.
