Carina
3D airway anatomy & bronchoscopy trainer
A life-size thorax you can fly through — the full bronchial tree to the segmental level, five lobes, great vessels, heart, esophagus and the complete IASLC node map. Look at it from the outside, or drive a scope down the lumen with the same three degrees of freedom you have in the bronchoscopy suite.
Launch the simulator →Desktop browser with WebGL2 and a keyboard. Phones and tablets won't work.
External view
- drag
- orbit the model
- scroll
- zoom
- right-drag
- pan
- hover
- name any structure — hovering a lymph node highlights it and reads out its station
The right-hand panel toggles each anatomical layer, lung opacity, and the label sets (structures, segmental B1–B10, node stations).
Inside the scope — "Enter scope"
The scope is a shaft threaded through the airway, not a free-flying camera, so it has the same constrained 3 degrees of freedom as the real thing. All keyboard — there is no mouse-look.
- insert · withdraw — withdrawing retraces the path you came in on
- shaft roll — torques the whole scope ( also work)
- tip flex — deflects the view, single plane. These are inverted on purpose: like the thumb lever on a real scope, pressing deflects the tip up, so what you learn here transfers to the instrument
- fine (precision) modifier
- re-center — straighten the tip
- Esc
- back out to the external view
Steering a bifurcation: you advance into whichever ostium the tip is pointing at. So roll to bring the branch you want into your flex plane, flex to point at it, then push in. The tip straightens itself as the shaft slides forward, so you don't have to re-center after every branch.
The numeric keypad mirrors every one of these, and a standard gamepad works if one is attached (R2/L2 advance·withdraw, left stick roll + flex, L1/R1 fine, B re-center). Stick travel is lever travel: how far you push is how far the tip flexes, and centring the stick holds the tip where it is. The stick follows the same lever convention as the arrows — pushing it down flexes the tip up.
Three things to try
- Realistic navigation (elastic rod) — the checkbox under Bronchoscopy swaps the guided rail for a physical scope: the shaft goes straight, the lens moves when the tip flexes, the wall takes deflection away, and a square push wedges. A panel shows the push, the lever against the tip and the shaft inside the airway.
- Navigation cases — pick a case, start it, and find the target segment yourself. The run is graded on time, wall contacts and path efficiency.
- Guide me — draws the route to the target as a glowing line down the lumen. It shows the way but never moves the scope, so you still fly it yourself.
- X-ray walls (EBUS view) — makes the airway translucent and draws nodes and vessels through it, i.e. what sits behind the wall at a given station when you're planning a TBNA.
