摘要： Embodiments of a surgical access port system that comprises a retractor that is adapted for being coupled to a cap and that is particularly useful in natural orifice surgery are described. The retractor comprises an outer ring, wherein the outer ring is configured to be disposed proximate the natural orifice of the patient and substantially surround the orifice; a tubular body; a funnel segment extending between and coupling the outer ring and the tubular body, wherein the funnel segment provides a diametric reduction between the relatively large diameter of the outer ring and the relatively smaller diameter of the tubular body, which is sized to fit within a natural orifice with minimal distention of the orifice; and an inflatable member disposed around the distal end of the tubular body, the inflatable member sized and configured to fit snugly around the tubular body in the deflated condition and to expand against the wall of the natural orifice in the inflated state to thereby stabilize and retain the retractor within the orifice.

摘要： Bipolar electrosurgical scissors for treating biological tissue include first and second scissor blades. A shearing surface and cutting edge of each blade is electrically neutral. The scissors include a pair of electrical connections for receiving electrical currents of opposing polarities. Each blade includes at least one first electrode and at least one second electrode positioned on a surface opposite the shearing surface. The at least one first electrode on the first blade and the at least one second electrode on the second blade are coupled to the first electrical connection. The at least one second electrode on the first blade and the at least one first electrode on the second blade are coupled to the second electrical connection. In a first energized state, the electrical connections deliver electrical current only to the first electrodes. In a second energized state, the electrical connections deliver electrical current to all of the electrodes.
