A handle assembly for a surgical stapler can comprise a rotatable actuation shaft. The actuation shaft can have a first rotational orientation in which it can actuate a jaw assembly in a repeatable open and close mode, a second rotational orientation in which it can actuate a jaw assembly in a staple firing mode, and a third rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include a rotational mechanism arranged to discretely position the rotatable actuation shaft in one of the rotational orientations. The rotational mechanism can be arranged for single handed operation such as by including a slidable switch or selector to rotate the actuation shaft.

An electrosurgical instrument includes jaws having an electrode configuration utilized to electrically modify tissue in contact with one or more electrodes. The instrument is removably connectable to an electrosurgical unit via an electrosurgical connector extending from the instrument and a receptacle on the electrosurgical unit. The electrosurgical instrument is rotatable without disrupting electrical connection to the electrodes of the jaws. One or more of the electrodes is retractable. The electrosurgical unit and instrument optimally seals and/or cuts tissue based on identifying the tissue and monitoring the modification of the tissue by the application of radio frequency energy.

Electrosurgical instruments and connections thereto

An electrosurgical system can include an electrosurgical generator, a feedback circuit or controller, and an electrosurgical tool. The feedback circuit can provide an electrosurgery endpoint by determining the phase end point of a tissue to be treated. The electrosurgical system can include more than one electrosurgical tool for different electrosurgical operations and can include a variety of user interface features and audio/visual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and direct current surgical appliances.

Devices, methods, and systems provide a surgical access device comprising an internal retractor device integrated with or coupled to a body wall or wound retractor. The wound retractor retracts an opening in a body wall into a body cavity, while the internal retractor permits a user to control the positions of internal structures within the body cavity, thereby permitting a user to define a surgical field. Embodiments of the internal retractor are adjustable.

Jaw assemblies for a surgical stapler are provided. The jaw assemblies comprise a first jaw having a first clamping surface and a plurality of staples disposed therein and second jaw assembly having a second clamping surface. The jaw assemblies can be actuated from a closed configuration in which the first clamping surface contacts or is adjacent to the second clamping surface to an open configuration in which the second jaw is pivoted away from the first jaw to a stapling position in which the second clamping surface is parallel to the first clamping surface and spaced apart from the first clamping surface. A pivoting link or sliding pivot joint can couple the second jaw to the first jaw to facilitate motion between the closed position, the open position, and the stapling position.

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.

A surgical stapler includes a jaw assembly at a distal end connected to a handle assembly that is configured to control the stapler and actuate the deployment of staples. The surgical stapler successfully eliminates intermediate caming portions commonly known as pushers that are located between the staples and a translating slider. The staples are located in pockets at an angle such that the base of the staple is parallel to an angled caming surface of the slider. The translating slider comes into direct contact with staples during deployment as the slider moves through each staple pocket where staples are partially supported by recesses along the slider pathway. The staples are deployed at an angle against the anvil surface. Because there are no pushers, a great deal of space is saved resulting in a much smaller diameter surgical stapler that is particularly suitable for laparoscopic stapling applications.

An electrosurgical generator arranged to supply radio frequency (RF) energy to fuse tissue is provided. The generator is arranged to supply RF energy through a removably coupled electrosurgical instrument to fuse tissue grasped by the instrument. The generator monitors a phase angle of the supplied RF energy and adjusts or terminates the supplied RF energy based on the monitored phase angle in comparison to predetermined thresholds and conditions to optimally fuse the tissue. The electrosurgical instrument conducts radio frequency energy to fuse tissue captured between the jaws and a blade to mechanically cut tissue between the jaws. A conductive post positioned on the jaw adjacent to the blade.

A tissue retractor comprising an outer ring, an inner ring, and a flexible, metal sheath extending therebetween is described. Embodiments of the inner ring comprise a flat or wedge-shaped conformation useful for insertion between muscle layers. Other embodiments of the inner ring include variable diameter inner rings, where the diameter can be adjusted as required and optionally locked into place, and reshapeable inner rings that permit a user to conform the inner ring to the anatomy of the patient when placing the inner ring.
