Bowel (intestinal wall) comprises the multilayered tissue structure of the small and large intestine.
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Cigarette Paper | Neonatal Enterocutaneous Anastomosis Simulator | Thin cigarette paper, especially when moistened, simulates the friable neonatal bowel wall. | ||
| Modeling Balloon | Trocar Placement Trainer | An inflated modeling balloon stands in for the bowel. | ||
| Flat Bed Sheet | Meckel's Diverticulectomy Simulator | A rolled woven sheet forms a tubular bowel segment. | ||
| Sausage | Abdominal Wall Defect Simulator (Medeiros) | Sausage forms the herniated bowel loops of the gastroschisis model, for visual recognition of herniated viscera. It is perishable, so that model is effectively single-use; the authors suggest a red cotton ball wrapped in cellophane tape as a durable substitute. Fake blood makeup colours the loops, and the source notes the blood can be mistaken for bowel damage.[1] | ||
| Glove | Acute Appendicitis Simulator, Appendectomy Simulator, Open Appendectomy Simulator (Matthews) | An exam or surgical glove forms the appendix–cecum–terminal ileum complex. In the Appendectomy Simulator the glove is inverted, the middle finger becomes the appendix body and the glove body the cecum cavity, the index finger is tied off and the fourth and fifth fingers suture-ligated. In the ALL-SAFE Acute Appendicitis Simulator the second finger of an inverted glove is packed with sand or dirt to give the firm, inflamed appendix, and fingers cut from a second glove are folded, taped and attached to the side of the cecum as the terminal ileum. In the Matthews open appendectomy model the third (middle) finger is the appendix, the base of the glove filled with cotton balls is the cecum, the thumb is left in place as the terminal ileum at the ileocecal junction, and the second, fourth and fifth fingers are excised. | ||
| Cotton balls | Appendectomy Simulator, Open Appendectomy Simulator (Matthews) | In the Appendectomy Simulator the cotton is thinned to about 1 cm and packed loosely into the middle finger of the glove with a haemostat — do not overstuff the tip. In the Matthews model cotton balls fill the base of the glove to form the cecum. | ||
| Ecoflex 00-30 | - | - | Bowel Anastomosis Simulator (Habti) | A 30 cm single-layer silicone segment cast in a 3D-printed mould with a replicated mucosal surface texture; one mould yields up to four segments. Shore 00-30 was one of the two samples the senior clinical team independently picked as most representative for texture, colour and thickness. All clinicians confirmed the prototype was "representative of the small bowel anastomosis tissue, especially the replicated mucosae, and that it responded well to suturing"; they noted knotting differs from real tissue because the simulator has more recoil than real bowel.[2] |
| - | - | - | Thoracoscopic Diaphragmatic Hernia Repair Simulator (Barsness) | Synthetic herniated viscera; material not specified in source. Multiple loops of artificial intestine are herniated through the diaphragmatic defect and reduced during the simulated thoracoscopic repair. The source rates them 3.50 / 5 for realism — the lowest of its tissue sub-items — and notes poor haptic feedback against real neonatal tissue.[3] |
| Synthetic fabric mesh + Styrofoam | Intra-abdominal Bleeding Simulator (Fernandes) | Fine synthetic-fabric mesh with a little polystyrene microsphere filling forms the small intestine and large bowel. The two are given different colours; the small intestine is fixed at its ends only, without a mesentery.[4] |
- Mesentery — carries vascular supply to bowel
- Peritoneum and Serosa — serosal covering of bowel
- Blood — mesenteric vessels
