Abstract: 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.

Abstract: A surgical simulator for surgical training is provided. The simulator includes a frame defining an enclosure and a simulated tissue model located inside the frame. The simulated tissue model is adapted for practicing a number of surgical procedures including but not limited to transanal excisions and transvaginal hysterectomies. Portions of the frame comprises a material adhesively compatible with the material of portions of the simulated tissue model to secure and suspend the simulated tissue model within the frame. The simulated tissue model may also include simulated vasculature configured to loop through apertures in the frame to secure and suspend the simulated tissue model within the frame.

Abstract: A bipolar electrosurgical fusion/sealer and dissector is provided that is arranged to simultaneously fuse and cut tissue captured between jaws of the instrument. The jaws include particularly positioned, shaped and/or oriented electrodes along with a compressible landing pad to perform the simultaneous fusion and cutting of tissue. An electrosurgical generator is arranged to supply RF energy through the instrument and monitors a phase angle of the supplied RF energy and adjusts or terminates the supplied RF energy based on the monitored phase angle to optimally fuse and dissect the tissue.

Abstract: A retractor/protector suitable for use in a surgical incision or a natural orifice comprises a longitudinal axis defining an instrument access channel extending from a proximal end to a distal end; a flexible outer ring; an inner ring; a flexible sheath extending between the outer ring and the inner ring; and at least one rigid segment adapted to attach to the flexible outer ring to thereby increase the rigidity of the outer ring. Embodiments of the retractor/protector are described that have interlocking and non-interlocking rigid segments. Embodiments are also described that have bases that insert into or under the flexible outer ring in addition to or in lieu of rigid segments to increase rigidity and/or provide support for a detachable cap.

Abstract: 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; and various stabilizing mechanisms surrounding the tubular body, sized and configured to stabilize and retain the retractor within the orifice. The stabilizing embodiments described herein are useful in all natural orifices and are of particular use in the vaginal surgery.

Abstract: A sensorized surgical instrument for training users laparoscopic surgical procedures is provided. The instrument includes at least one sensor selected from a group consisting of a strain gauge, accelerometer, magnetometer, and gyroscope. The sensor is attached directly to a handle of the instrument. A shaft assembly having a tool tip is interchangeably connectable to the handle. The sensor is connected to a computer configured to provide feedback useful to the user for improving the user's surgical skills. The feedback includes the time to complete a procedure, economy of motion, smoothness of motion and the force exerted at the tool tip.

Abstract: Simulated tissue structures and methods of manufacturing are provided. The simulated tissue structures are particularly useful for placement inside abdominal simulators for practicing laparoscopic surgical techniques. One simulated tissue structure includes a combination of two materials that are attached together wherein one of the materials forms a hollow anatomical structure configured to contain the other material. The two materials are attached in an anatomically advantageous manner such that the inner surface of the outer material closely conforms to the outer surface of the inner material. Another simulated tissue structure includes a plurality of layers wherein at least one layer is applied by printing the layer with at least one stencil to impart one or more functional characteristic to the simulated tissue structure.

Abstract: A tissue retrieval system including a tissue retrieval bag deployable by an actuator from an introducer and suspended in an open configuration by support arms can be serially redeployed between a partially or fully stowed configuration and a first deployed configuration to be used in procedures to collect multiple samples. The system can include defeasible proximal and distal stop mechanisms to limit movement of the actuator for serial redeployment. The tissue retrieval system can include a retention latch to couple a bead of the tissue retrieval bag to the actuator with the retrieval bag in the first deployed position and a user-selectable deployment release to allow deployment of the retrieval bag to a fully deployed position where it is released from the actuator. A bead stop is positioned to engage the introducer to prevent reintroduction of the bead and bag into the introducer once the bag has been fully deployed.

Abstract: A cannula assembly having a retention member and a method of manufacture of the cannula assembly is provided. The cannula assembly includes a cannula and a sleeve disposed around the cannula from a proximal end to a distal end. The sleeve can include a balloon formed by a stretch blow molding process following local heating once advanced over the cannula. Once formed, the balloon can be conditioned to constrict against the cannula. A conditioning aid can be advanced over the balloon when it is still formable to constrict the balloon against the cannula.

Abstract: A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.
