Claim 0:
1. A surgical device for laparoscopic surgery, comprising:
an inner cannula having a first passageway extending from a distal end of the inner cannula to a proximal end of the inner cannula, wherein the inner cannula is rigid;
a handle connected to the proximal end of the inner cannula;
an outer cannula, wherein the outer cannula is flexible and electrically nonconductive, wherein the outer cannula shields the inner cannula from electrical discharges, and wherein the outer cannula has a second passageway extending from a distal end of the outer cannula to a proximal end of the outer cannula wherein at least a portion of the inner cannula is located and translatable within the second passageway, there being clearance between an interior surface of the outer cannula and an exterior surface of the inner cannula to allow fluid flow therebetween, and wherein the outer cannula is disposed within a trocar to a surgical site; and
a clamp fixedly connected to the proximal end of the outer cannula and operable to establish a predetermined shape of a section of the outer cannula, the shape forming a releasable seal between the outer cannula and the inner cannula and wherein the section extends beyond the distal end of the inner cannula.
