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

The present invention provides a surgical training device for training laparoscopic first entry surgical techniques. The training device includes a simulated abdominal wall that is penetrable with an optical trocar. A receptacle containing a tissue simulation is located inside the receptacle. The tissue simulation is observable via scope placed inside the optical trocar. Upon penetration of the one or more of the simulated abdominal wall and receptacle, the tissue simulation appears to translate distally relative to the simulated abdominal wall. The distal translation is effected by a variety of ways including the release of negative pressure inside the receptacle upon penetration and the expansion of an elastic wall of the receptacle with the introduction of fluid under pressure into the receptacle.

Advanced first entry model for surgical simulation

A portable surgical training device is provided. The trainer includes a top cover spaced apart from a base to form a simulated body cavity for locating model organs that are substantially obscured from the field of view of the user. The top cover includes a video display, fixed insertion ports and interchangeable inserts containing simulated tissue layers. The training device has open sides for demonstrating and training lateral surgical techniques including a simulated or live tissue colon attached to a support leg for simulating transanal minimally invasive surgery. A training endoscope with an adjustable focal length for use with the trainer and, in particular, with optical trocars is disclosed. The surgical trainer can be angled and is well suited for training laparoscopic surgery techniques and demonstrating surgical instruments.

Portable laparoscopic trainer

A simulated abdominal wall model that is ideal for practicing laparoscopic first entry surgical techniques is provided. The model includes a simulated abdominal wall portion captured between two frame elements of a support. The support is connectable to a surgical trainer. When connected to the trainer, the model provides a penetrable abdominal tissue portion for accessing an internal cavity of the trainer. The simulated abdominal wall includes a plurality of layers including a skin layer, a fabric posterior rectus sheath layer, a simulated fat layer of low-resilience polyurethane foam and at least two layers that provide distinctive haptic feedback upon penetration of the simulated transversalis fascia and muscle layers. The simulated abdominal wall includes a simulated umbilicus across several layers of simulated tissue.

First entry model

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.
