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

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 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 tissue structure for practicing surgical techniques is provided. In particular, a realistic organ model or tissue portion for practicing the removal of a tumor or other undesired tissue followed by suturing a remnant defect as part of the same surgical procedure is provided. The simulated tissue structure includes an artificial tumor disposed between layers of elastomeric material and mounted on a simulated organ wall or tissue portion. The simulated tissue structure is modular and interchangeable. At least one of the layers includes a mesh reinforcement. A defect comprising two juxtapositioned surfaces defining a gap between the surfaces is created in the simulated tissue structure and the trainee practices tumor removal and closure of the gap by suturing in a laparoscopic environment.

Simulated tissue structure for surgical training

Systems and methods for tissue containment and retrieval are disclosed. The containment system includes a primary chamber interconnected with a secondary channel extending from the primary chamber. A tissue specimen is mobilized inside a body cavity and placed into the primary chamber through a first opening. The first opening is pulled through a first incision or orifice and the narrower secondary channel is placed at a second incision or orifice. A second opening at the end of the secondary channel permits observation via a scope inserted through the second opening of the tissue specimen in the primary chamber undergoing morcellation via the first opening. Other systems and methods for deployment, containment, debulking and sealing of the second opening to create a closed system for the safe retrieval of the tissue specimen are provided.

Systems and methods for tissue containment and retrieval

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

An anatomical model for surgical training is provided. The model includes a first layer simulating a liver and a second layer including a simulated gallbladder. A third layer having an inner surface and an outer surface is provided between the first and second layer. The outer surface of the third layer is adhered to the first layer at location around the simulated gallbladder and the simulated gallbladder is adhered to the inner surface of the third layer. A fourth layer is provided that overlays both the second layer and the simulated gallbladder. A frame is embedded within the first layer and is connectable to a support. The model provides a substantially upright projection of a simulated gallbladder and liver in a retracted orientation ideally suited for practicing laparoscopic cholecystectomy when inserted inside a simulated insufflated cavity of laparoscopic trainer.

Gallbladder model

A surgical training model that includes a simulated tissue having a tubular shape that is connected to a tissue holder is provided. A portion of the simulated tissue overhangs the distal end of the tissue holder to simulate a cuff-like entry to the vaginal vault or resected intestine suitable for practicing laparoscopic closure of the vaginal vault, intestine or other organ via suturing or stapling. Two concentric tubular structures are also arranged over the same tissue holder. A second model includes two portions of simulated tissue that are held by two holders such that the simulated tissues are adjacent making the model suitable for practicing different types of anastomosis procedures. A third model includes two holders with a single or double tubular simulated tissue structure connected to and spanning a gap between the holders. The model isolates the step of closing a cylindrical opening for the purpose of repeated practice.

Surgical training model for laparoscopic procedures

A system for training a clinician in energy-based surgical techniques that advantageously does not require the simulated tissue to be electrically conductive is provided. The simulated tissue comprises one or more materials. A heat generator is configured in the shape of a medical instrument typically encountered in energy-based surgical procedures such as electrosurgery or electrocautery. The instrument delivers sufficient heat to melt at least one of the materials in order to simulate energy-based surgical techniques such as excising target material. The one or more materials are configured in the simulated tissue such that their relative thermoplasticity defines a predetermined surgical pathway of a desired clinical outcome.

Advanced surgical simulation

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.
