TissueDB/Materials/Bovine trachea (ex vivo)
Ex vivo bovine trachea serves as a tissue-simulating material in medical simulation training. It suits training that needs tracheal anatomy, ring palpation, and needle puncture practice. Documented application: bronchoscopy-guided percutaneous dilatational tracheostomy (BG-PDT) training. Kattan et al. mounted a 20 cm segment (from below the larynx to the carina) on a PVC half-pipe cradle. One segment supports up to 6 training iterations per specimen.[1]
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Trachea | BG-PDT Simulator (Kattan) | Real mammalian tracheal tissue. The operator palpates the cartilage rings and makes a needle puncture. One 20 cm specimen allows 6 iterations (Kattan et al. 2019).[1] |
Used In Simulators
| Simulator | Purpose | Notes |
|---|---|---|
| Bronchoscopy-Guided Percutaneous Dilatational Tracheostomy Simulator (Kattan) | Tracheal ring anatomy for palpation and needle puncture practice | 20 cm segment (below larynx to carina). 6 iterations per specimen. Approximately US$1.7 per use[1] |

[edit source]Overview
[edit source]Ex vivo bovine trachea is the windpipe (trachea) harvested from cattle, used fresh or thawed as a biological tissue-simulating material. Like all mammalian tracheas, it is a tube of firm, incomplete C-shaped cartilage rings. Connective membrane joins the rings, and mucosa lines the tube. The structure gives natural ring landmarks for palpation and tissue resistance to needle puncture. It is an abattoir or butcher by-product. Keep it refrigerated or frozen until use, and discard it after a limited number of uses. The documented application uses a 20 cm segment, from below the larynx to the carina. One specimen supports about 6 training iterations at roughly US$1.7 per use (Kattan et al. 2019).
