TissueDB/Tissues/Vas Deferens
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. Kept as its own tissue class per Dr Catherine Mohr (24 June 2026).
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Dobbhoff feeding tube | – | – | Laparoscopic Inguinal Hernia Repair Simulator (Kurashima) | The feeding tube's firm, rolling feel reproduces the vas deferens during dissection and survives repeated practice (part of the reusable set); bundled with the spermatic cord vessels.[1] |
| Coloured elastic loop (Ethiloops or lanyard) | – | – | Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | One coloured elastic loop (e.g. Ethiloops or a lanyard) set inside the bottle neck as the vas deferens, colour-coded against the testicular artery to train duct-versus-vessel discrimination.[2] |
| Central venous catheter segment (9.5 Fr) | – | – | Laparoscopic Inguinal Hernia Repair Simulator (Hanssen) | A 9.5 Fr central venous catheter segment stands in for the vas deferens, bundled with the epigastric and spermatic vessel wires inside the spermatic-cord assembly.[3] |
