TissueDB/Tissues/Bronchial Tissue
(Redirected from TissueDB/Tissues/Main Bronchus)
The bronchi are the airways branching from the trachea at the carina into right and left main bronchi, then into lobar and segmental bronchi. Bronchial anatomy is foundational for flexible fiberoptic bronchoscopy training, where residents must learn to recognise each segmental bifurcation and orient scope position from the endoscopic view. Simulators that represent the bronchial tree typically emphasise anatomical recognition over tactile fidelity, since bronchial wall mucosa is difficult to replicate with low-cost materials.
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Iron-wire-plus-paper-mache scaffold (no tactile fidelity) | Yes | No | Bronchoscopy Anatomical Trainer (Di Domenico) | All bronchial segments labelled per the international classification; endoscopic-view correspondence verified by the authors at three bifurcations. Source: Di Domenico S, Simonassi C, Chessa L. Interactive CardioVascular and Thoracic Surgery 2007;6(4):567–569. PMID 17669940.[1] |
| TPU (EOS TPU 1301) | - | - | Massive Hemoptysis Simulator (New) | [2] |
| Corrugated ventilator tubing (15 cm) | - | - | Cricothyrotomy Simulator (Kei) | Duct-taped to the distal (inferior) opening of the 3D-printed trachea model and sealed at its open end with duct tape; the source states this "will serve as the carina". Two air vents, punctured with a scalpel and smaller than the diameter of a bougie, let the bag-valve-mask air the instructor delivers escape through the cricothyroid incision as the flash-of-air cue.

| Stratasys Agilus30 | Paediatric Airway Management Trainer (Carter) | The carina at the tracheal bifurcation, printed as part of a paediatric airway model that runs from the trachea to the carina and is directly visualised on rigid bronchoscopy — the carinal view was recorded by a consultant otolaryngologist. Single-object multi-property print on a Stratasys Polyjet J750 at 14-micron layers, from CT data of a 4 kg five-month-old infant; Agilus30 was chosen over the Vero and Tango photopolymers for greater tissue fidelity. Qualitative demonstration only — no formal validity study.[4] |
