TissueDB/Materials/Elastic ties
License: CC-BY-SA-3.0 by Bill Ebbesen
Elastic ties are small elastic loops, bands, or strips — including hair elastics, ponytail holders, rubber bands and elastic bands — used in low-cost surgical simulators to secure components, apply tension, or restrain soft parts. They are used both as fine tubular tissue analogues and as fixation elements.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Bowel segmentation | Meckel's Diverticulectomy Simulator | Secure rolled cloth bowel at regular intervals for handling practice — the build uses 10 rubber bands, pushed through eight holes cut 4 in (10 cm) apart under the rolled bed sheet and tied to secure the roll, with further bands forming the root of the mesentery and the ileocecal valve.[1] | ||
| Vas deferens | Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | One elastic loop (colour A) — e.g. Ethiloops or a "scoubidou" lanyard — set inside the bottle neck and taped in place. Colour-coded against the testicular artery to train duct-versus-vessel discrimination.[2] | ||
| Testicular artery | Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | One elastic loop (colour B, contrasting) — e.g. Ethiloops or a "scoubidou" lanyard — set inside the bottle neck and taped in place. Colour-coded against the vas deferens to train duct-versus-vessel discrimination.[2] |
Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Suture Material | Fine knot-tying practice on a tissue substrate | Higher cost, single-use, requires substrate |
| Silicone Tubing | Vessel simulation with elastic properties | Higher cost, requires careful handling |
