Laparoscopic Surgery

EndoSim developed a realistic simulation model of common laparoscopic procedures using ex-vivo explants. A domed lid includes a rubber membrane that allows insertion of laparoscopic ports and instruments. The ex-vivo specimens used in the EASIER 1 or 2 model consist of porcine tissue or bovine tissue harvested at USDA inspected slaughterhouses as a byproduct of the meat production industry. The ex-vivo tissue promotes a realistic laparoscopic experience using commercially available laparoscopic devices. Of highest importance, is the haptic feedback of real tissue simulation models that provide a comparable training environment as in a real patient.

Our specimens and trainer rentals are shipped express for on-time and fresh arrival. All specimens are shipped frozen and will require thawing and refrigerated storage upon arrival. Please be sure to include desired delivery date with your order.

Natural Orifice Translumenal Endoscopic Surgery (NOTES)

For the simulation of NOTES, a complete porcine peritoneal cavity explant is used in the EASIER model for the simulation of endoluminal and transluminal surgical procedures.

This model is useful for the training of basic NOTES procedures, such as establishing transgastric and transcolonic access, peritoneal exploration, and tissue biopsy. For the more advanced ‘digestivist’, the EASIER can facilitate organ resection (cholecystectomy, distal pancreatectomy, liver lobe resection, hysterectomy, oophorectomy) or gastrointestinal anastomosis techniques (gastrojejunostomy, partial gastrectomy, colectomy). Multiple gastrotomies or colotomies can be performed in a single model. To facilitate multiple participants during gastrotomy or colotomy, each procedure ends by closing the perforation with a variety of closure devices.

In addition to the endoscopic view, surgical procedures can be observed through the clear acrylic cover. By removing the lid, a direct assessment of tissue incision, resection, and clip application can be undertaken by gross inspection of the the surgical site.

In contrast to using live animals for NOTES training, the use of ex-vivo specimens obtained from the meat industry, does not involve ethical concerns and is not subject to IRB approval.

For the simulation of laparoscopy or hybrid NOTES procedures a special cover with laparoscopic ports is used instead of the clear lid. This permits the use of commercially available laparoscopic instruments.

Skin Suture Pad

Skin samples from real porcine skin can be used to practice suturing such as closing cuts and lacerations with simple and advanced interrupted suturing, subcuticular suturing, continuous suturing, skin stapling or application of adhesive strips

Surgical Simulation Models:  

Complete Simulation Model = Trainer (hardware) + Real Tissue Specimen (software)

Our simulation models use two components: a plastic trainer (hardware) used in conjunction with a disposable ex-vivo specimen (software). Some disposable specimens are hybrid models combining plastic, silicon with real tissue. These types of models are single-use disables cartridges. The use of cartridges allows an easy setup and exchange of simulation models even without pre-experience.

Thompson Endoscopic Skills Trainer (TEST)

The Thompson Endoscopic Skills Trainer (TEST) is a portable training tool designed to assess and improve endoscopic skills.

The first of its kind, the TEST is broken up into five task-oriented compartments, each of which develops a particular skill used in endoscopy. Capable of distinguishing among a wide range of skill levels, from novice to advanced endoscopist, the TEST is a safe, effective, and objective measure of ability. Additionally, as a training tool, the TEST may be used by beginner endoscopists to familiarize themselves with endoscopic maneuvering before proceeding to procedures inside patients, and by more advanced endoscopists to maintain their skills
