Claim:
1. A blood vessel harvesting system comprising: a blunt dissection tip comprising a transparent cone having a taper to a vertex and a first axis extending through the vertex of the cone; an elongated shaft connected at a distal end to the dissection tip, wherein the elongated shaft comprises an optical path that extends to the transparent cone of the dissection tip; a raised collar forming a step facing the dissection tip, wherein the step extends in a circle and the step is substantially perpendicular to the first axis, and the raised collar has a central axis that is substantially collinear with the first axis, and the first axis is substantially collinear with a longitudinal central axis of the elongated cylindrical shaft; and a cutting assembly comprising at least one blade disposed to extend longitudinally along an offset axis that is substantially parallel to the first axis of the cone and offset from the first axis of the cone, and at least one electrode that contacts a blood vessel to be transected while captivated by the at least one blade, wherein the at least one electrode is disposed on the blunt dissection tip, and wherein the at least one blade is moveable in a slot and relative to the elongated shaft to enable cutting of the blood vessel external to the taper and that is viewable through the transparent cone of the dissection tip via the optical path of the elongated shaft.
