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.

A visual insufflation obturator is provided. The obturator includes seals, valves, screens and/or various other tip features to eliminate the ingress of fluids, matter and/or gas that can disrupt the visual field of the laparoscope disposed within the obturator. The obturator provides additional features such as lens and anti-fog features to further increase visibility of the scope, efficiently insufflate the patient and ultimately provide an access channel into the insufflated abdomen once the visual insufflation obturator is removed.

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.

Phase end point determination is provided to automatically halt the application of energy to tissue. Prior to the application of energy, the phase end point determination is identified by measuring the product of permittivity and conductivity of the tissue to be treated. 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.

An electrosurgical tool can be used to fuse tissue. The electrosurgical tool can include a jaw assembly, an elongate shaft, and a handle assembly. Actuation of the handle assembly can actuate the jaw assembly. The elongate shaft can be rotatable without disrupting electrical connection to the jaw assembly. The electrosurgical tool can include a cutting blade to separate fused tissue. The electrosurgical tool can also include a jaw assembly configuration or an exterior cutting electrode to improve surgical access with the tool.

An electrosurgical tool can be used for tissue dissection. The tool can include several electrodes positioned on a jaw assembly. The electrodes can be selectively connected to a power source in a cutting arrangement or a coagulation arrangement. Switching from the cutting arrangement to the coagulation arrangement can be provided by opening and closing a handle to actuate the jaw assembly.
