TissueDB/Materials/Elastic ties

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 serve in two roles. As tissue analogues, two contrasting-colour elastic loops stand in for the vas deferens and the testicular artery in a paediatric laparoscopic inguinal hernia trainer, colour-coded to train duct-versus-vessel discrimination.^[1] As fixation elements, bands maintain orientation and anchor tissue during ligation and dissection practice.^[2]

Tissues

Tissue	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.^[2]
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.^[1]
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.^[1]

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
