Woven Cloth is an inexpensive textile made by interlacing warp and weft threads at right angles — cotton, polyester, or a cotton-poly blend. Plain-weave (threads crossing one-over-one-under, as in a bed sheet or muslin) and twill (a diagonal-rib weave, as in denim) are the everyday forms; both are grain-dependent, meaning they barely stretch along the thread directions and give only on the diagonal (the bias) — unlike knitted cloth, which is looped and stretches in every direction, and felted cloth (felt), which is matted fibre with no threads or grain. It is sold everywhere as bed sheets, flat bed sheets, dress and craft fabric, fabric sheets, plain white fabric, muslin, calico, chambray, canvas and cotton duck — by the yard or in rolls, typically 90–115 cm (36–45 in) wide,[1] at fabric retailers and craft suppliers. In medical simulation it stands in for thin, membranous, drapeable tissues — mesentery, peritoneum, bowel wall and fascia — and as a cuttable outer skin layer. You work with it by cutting to size, then rolling it into tubular structures (bowel), bunching it for a mesentery root, draping single layers over organ models for peritoneum, or layering it over foam or silicone as fascia or skin. Its tear resistance, soft drape and easy cutting make it a low-cost analogue for dissection and handling practice.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Ovary | Laparoscopic Ectopic Pregnancy Simulator | Woven fabric — small (~5 × 5 cm) squares folded into round balls and secured, positioned at the tube origin for anatomical orientation. | ||
| Bowel | Meckel's Diverticulectomy Simulator | A rolled portion of a 76 × 61 cm flat bed sheet forms the tubular ileal segment (and its Meckel's diverticulum) for laparoscopic bowel-handling practice. | ||
| Mesentery | Meckel's Diverticulectomy Simulator | As a flat bed sheet, the unrolled ~35.56 cm portion is bunched to form the mesentery root attachment to the bowel. | ||
| Meckel's Diverticulum | Meckel's Diverticulectomy Simulator | From the flat bed sheet: 3–6 cm of the tube wall pulled outward from the bowel and secured with a rubber band to form the diverticulum. | ||
| Skin | Cricothyrotomy Simulator (Aho) | Outermost woven-fabric layer wrapped over the model as the skin the trainee incises first; a cuttable outer surface (Aho et al. 2015).[2] | ||
| Fascia (aponeurosis) | Appendectomy Simulator, Open Appendectomy Simulator (Matthews) | As cotton fabric: a sheet stands in for the fibrous aponeurosis — the external oblique aponeurosis in the Matthews eight-layer wall — layered into the abdominal-wall stack. The ASAP materials list sells it at a stock size of 12 cm × 22 cm.[3] |
