The vas deferens (ductus deferens) is the muscular tube that carries sperm from the epididymis to the ejaculatory duct. Within the spermatic cord it runs beside the testicular vessels as a firm, distinctly rolling structure. Keeping it intact protects fertility, so it is a critical structure to preserve in inguinal hernia repair. Simulators give it a separate firm tube- or cord-like stand-in that trainees must tell apart from the vessels. It is kept as its own tissue class.
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Feeding tube | – | – | Laparoscopic Inguinal Hernia Repair Simulator (Kurashima) | Dobbhoff feeding tube. The feeding tube's firm, rolling feel reproduces the vas deferens and survives repeated practice.[1] |
| Elastic cord | – | – | Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | One coloured elastic loop (e.g. Ethiloops or a lanyard) as the vas deferens.[2] |
| Central venous catheter segment | – | – | Laparoscopic Inguinal Hernia Repair Simulator (Hanssen) | A 9.5 Fr central venous catheter segment stands in for the vas deferens.[3] |
| Elastic cord | Pediatric Inguinal Hernia Repair Simulator (Heo) | White elastic string representing the vas deferens.[4] |
