Yarn (thread, embroidery floss, twine) is synthetic or natural fiber used in surgical simulation to represent linear structures such as blood vessels, for vascular anastomosis and knot-tying training.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Appendiceal Artery | Appendectomy Simulator, Acute Appendicitis Simulator, Open Appendectomy Simulator (Matthews) | Yarn represents the appendiceal artery as a ligation target.[1][2][3] | ||
| Mesoappendix (red yarn within scrub-cap) | Open Appendectomy Simulator (Matthews) | Red yarn wrapped in scrub-cap material forms the mesoappendix — a scrub cap folded around a piece of red yarn is attached to the third finger of the glove to represent the mesoappendix and the appendiceal artery.[1] |
Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Silicone tubing | Realistic vessel wall thickness | Higher cost; more complex setup. |
| Non-sterile suture | Most realistic texture for suture manipulation training | Higher cost per session. |
| Felt | Fascial plane simulation | Not suitable for vascular anastomosis training. |
