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.

Electrosurgical system

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.

Surgical access device comprising internal retractor

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.

Multifunctional surgical access system

A trocar surgical seal or surgical access device is provided. The trocar surgical seal comprises first and second supports coupled together by a film passageway. The trocar surgical seal provides an instrument seal for instruments inserted therethrough. The trocar surgical seal occupies minimal surgical space.

Trocar surgical seal

An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed. The instrument comprises a shaft having an insufflation channel extending between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end. A tip is at the distal end and a vent hole is formed in the tip being in connection with the insufflation channel and adapted to expel fluid under pressure to insufflate the abdominal region. The tip is formed of a transparent material to facilitate visualization of the abdominal wall and region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel.

Insufflating optical surgical instrument

The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure.

Medical tubing having variable characteristics and method of making same

The invention is directed to a bladeless trocar obturator to separate or divaricate body tissue during insertion through a body wall. In one aspect, the obturator of the invention comprises a shaft extending along an axis between a proximal end and a distal end; and a bladeless tip disposed at the distal end of the shaft and having a generally tapered configuration with an outer surface, the outer surface extending distally to a blunt point with a pair of side sections having a common shape and being separated by at least one intermediate section, wherein each of the side sections extends from the blunt point radially outwardly with progressive positions proximally along the axis, and the shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. With this aspect, the tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers. The side sections include a distal portion and a proximal portion, the distal portion of the side sections being twisted radially with respect to the proximal portion of the side sections. The intermediate section includes a distal portion and a proximal portion, the distal portion of the intermediate section being twisted in a first radial direction and the proximal portion of the intermediate section being twisted in a second radial direction opposite the first radial direction.

Bladeless optical obturator

An incrementally adjustable wound retractor (), having a first ring () with a diameter greater than the desired diameter of the wound incision, a flexible second ring (), having a lumen and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve (), disposed in a generally cylindrical form between the first and second rings (), where the second ring may be rolled over itself to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.
