Peritoneum and serosa are thin, transparent membranes lining the abdominal cavity and covering abdominal organs, simulated to train delicate handling and safe peritoneal entry techniques. Serosal surfaces are those smooth outer linings of the organs in the peritoneal, pleural and pericardial cavities. The pericardium is the fibroserous sac around the heart, an outer fibrous layer over an inner serous one. An organ capsule is the thin fibrous membrane enclosing a solid organ such as the liver, the kidney or the spleen. Periosteal tissue, the fibrous membrane covering bone, folds in here with those other organ coverings.
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Plastic Film | Trocar Placement Trainer, Appendectomy Simulator, Laparoscopic Ectopic Pregnancy Simulator, Open Appendectomy Simulator (Matthews), Laparoscopic Inguinal Hernia Repair Simulator (Kurashima), Medeiros Abdominal Wall Defect Simulator | Trocar Placement Trainer, Appendectomy Simulator, Laparoscopic Ectopic Pregnancy Simulator, Open Appendectomy Simulator (Matthews) and Laparoscopic Inguinal Hernia Repair Simulator (Kurashima): thin transparent peritoneal membrane. Medeiros Abdominal Wall Defect Simulator, omphalocele model only: yellow cellophane (plastic film) forms the peritoneal sac covering the herniated viscera. The gastroschisis model has no covering sac — that absence is one of the signs distinguishing it from omphalocele.[1] | ||
| Semitransparent fabric mesh | Intra-abdominal Bleeding Simulator (Fernandes) | Semitransparent waterproof fabric membrane isolating peritoneal cavity from retroperitoneum; allows visual identification of underlying structures[2] | ||
| Masking tape + Contact adhesive paper | Laparoscopic Inguinal Hernioplasty TAPP 3D Simulator (Pires de Melo Filho) | Masking tape layered with Contact adhesive paper covers the entire internal model surface corresponding to the abdominal cavity. Allows anatomical structures to remain visible through transparency, enabling Stage 1 (peritoneum opening) and Stage 5 (peritoneum closure) maneuvers.[3] | ||
| Non-lubricated condom | Pediatric Inguinal Hernia Repair Simulator (Heo) | Serves as the hernia sac in each modular cartridge. Membrane characteristics and global availability drove material selection; latex finger cots and plastic kitchen wrap were rejected during iteration.[4] | ||
| Self-adhesive plastic field | Laparoscopic Inguinal Hernia Repair Simulator (Hanssen) | Self-adhesive plastic field (Ioban™ 6648, 3M®, St. Paul, MN, USA) applied over the entire assembled hernia model to allow realistic dissection of the pre-peritoneal space without bleeding artefact.[5] | ||
| Transparent surgical glove | Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | Second (transparent) surgical glove placed over the assembled bottle-funnel structure with fingers cut a few centimetres below the bottle neck. The transparent material supports visual dissection planes during simulated repair.[6] | ||
| Gelatin-Glycerol Gel | Patent Ductus Arteriosus Ligation Simulator | Parietal pleura cast as part of the gelatin-glycerol PDA model; trainees dissect it off the aorta to expose the PDA before ligation. | ||
| Gaffer Tape over cellophane (Plastic Film) | – | – | Chest Tube Insertion Simulator (Man-O-War) | Gaffer tape moulded over cellophane along the intercostal spaces, mimicking the parietal pleura.[7] |
| Disposable shower cap, red-dyed fluid | - | - | Emergency Department Thoracotomy Simulator (Misra) | A disposable shower cap filled with red-dyed fluid, tied to the heart model to mimic the tamponade-filled pericardial sac; incised during pericardiotomy. Releasing the cap represents tamponade decompression and gives the resident the visual and tactile cue of tamponade release. One cap is used per training run.[8] |
