20140087345 | SURGICAL TRAINING MODEL FOR LAPAROSCOPIC PROCEDURES - 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. | 03-27-2014 |

20140087347 | SURGICAL TRAINING MODEL FOR LAPAROSCOPIC PROCEDURES - A surgical training device includes a model comprising a simulated tissue portion mounted in selectable tension onto a plurality of posts connected to a base. Each post includes at least one notch configured for retaining the simulated tissue portion. Mounting the simulated tissue portion that is in the form of a sheet in notches of different heights creates an angled installation of simulated tissue upon which surgical techniques such as cutting and suturing can be practiced in a simulated laparoscopic environment. More than one sheet can be mounted and each sheet can be mounted with selectable tension by pulling the sheet more or less as desired onto the posts. One variation includes a simulated tumor disposed between sheets, angled or wobbly posts and textured and imprinted simulated tissue surfaces to provide various levels of dynamism and difficulty for surgical skills training in a laparoscopic environment. | 03-27-2014 |
20140087348 | SURGICAL TRAINING MODEL FOR LAPAROSCOPIC PROCEDURES - A surgical training device is provided. The training device includes a practice model comprising a base with a plurality of eyelets connected to the outer surface of the base. The plurality of eyelets defines at least one predetermined pathway for practicing the passing of at least one needle and suture through the eyelets of the predetermined pathway. Various eyelets are described including angled, flexible, deflectable, interchangeable, retractable, rotatable and ones having apertures of various shapes and sizes. The predetermined pathway is marked with markings on the outer surface of base or with color-coded eyelets. Suture pathways define anatomical pathways as well as differing skill levels. The model provides a platform for practicing hand-to-hand transfer and depth perception among other skills required in laparoscopic procedures. | 03-27-2014 |
20140093852 | SURGICAL TRAINING MODEL FOR LAPAROSCOPIC PROCEDURES - A model for practicing laparoscopic surgical skills is provided. The model includes a base having a plurality of practice stations at the upper surface. The practice stations include a cover having a first closed position in which a cavity is concealed beneath the cover and a second open position in which the cover is moved to uncover the cavity. The covers are connected to the surface in a number of ways to provide a variety of haptic responses useful in fine-tuning laparoscopic surgical skills. The cover is configured as a door hinged with or without a bias, a flexible flap, a sliding cover, a lid, and a penetrable sheet. An object for removal is hidden inside the cavity underneath the cover for practicing hand-to-hand transfer of instruments, use of both hands, switching instruments and determining and visualizing tissue planes in a laparoscopic environment. | 04-03-2014 |
20140093854 | SURGICAL TRAINING MODEL FOR TRANSLUMINAL LAPAROSCOPIC PROCEDURES - A model for practicing laparoscopic surgical skills is provided. The model comprises a body having an elongate lumen and a plurality of eyelets connected to an inner surface of the lumen. The plurality of eyelets defines at least one pathway for practicing the passing of at least one needle and suture through the eyelets. The model further includes a staging area with removable objects having apertures configured to be placed onto hook-like eyelets. The model provides a platform for practicing hand-to-hand transfer, depth perception among other skills required in laparoscopic procedures within a confined tubular space. The model may be placed inside a laparoscopic trainer in which the practice is performed in a simulated laparoscopic environment and observed on a video display. | 04-03-2014 |
20140342334 | HERNIA MODEL - A model for practicing transabdominal pre-peritoneal (TAPP) and total extraperitoneal (TEP) approaches for laparoscopic hernia repairs is provided. The model simulates an insufflated space between the abdominal muscles and peritoneum. A spring layer may be incorporated to provide a realistic resiliency to the model while in the simulated insufflated configuration. At least one hole is provided in the model from which synthetic tissue protrudes to simulate a hernia. The model is used to selectively simulate direct, indirect and femoral inguinal hernias as well as incisional hernias by removably placing the protruding simulated tissue into any one of several openings. The model contains all important anatomical structures and sits on a base frame or is connected to a rigid simulated pelvis. When located inside a laparoscopic trainer with an angled top cover, the model provides an ideal simulation for teaching and practicing laparoscopic hernia repair. | 11-20-2014 |
20140370477 | GALLBLADDER 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. | 12-18-2014 |
20150031008 | FIRST ENTRY MODEL - 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.
