Thumb
Move the flexion lever without locking the hand. Predict the distal-tip response before advancing.
Room 01 · Instrument anatomy
Anatomy of the flexible bronchoscope.
The control body, flexion lever, ports, insertion cord, and distal tip form one connected instrument. Learn the parts first. The next rooms show what the hand does with them.

Model-specific controls
BFlex and Ambu aScope systems share the major functional parts shown here, but control names, locations, ports, accessories, and display connections vary by model. Exact device-specific labels remain gated for equipment verification.
Room 02 · Establish the hold
How to hold the bronchoscope.
Support the control body without locking the hand. Keep the thumb free to move the flexion lever and the wrist free to rotate the instrument. The other hand manages the insertion cord and preserves useful tension.
Thumb remains freeWrist remains mobile
Secure, not clenched
The hand supports the control body. Excess grip tension makes small thumb and wrist inputs harder to separate.
Thumb at the lever
Position the thumb so it can deflect and release the lever without forcing the rest of the hand to move.
Wrist free to rotate
Rotation changes the plane in which lever deflection acts. A fixed wrist removes one of the principal control inputs.
Other hand on the cord
Manage slack, loops, advancement, and light tension proximally rather than steering by grabbing the distal shaft.
Room 03 · Control the tip
How to control the bronchoscope.
Thumb, wrist, and tension are separate inputs. Control comes from coordinating them without letting one movement substitute for another.
Wrist
Rotate the control body to change the plane of deflection and reorient the visual field.
Tension
Manage the insertion cord so thumb and wrist inputs produce a predictable response at the distal tip.
The model is approved for implementation. Exact ergonomic and device-specific coaching remains subject to equipment testing and clinical review.
Room 04 · Drive to the target
How to move the tip where you intend.
Successful driving is a repeating sequence: locate the target, orient the plane of movement, deflect toward it, then advance only while the tip continues to follow the intended path.
The image closes the loop
The screen shows the combined result of thumb, wrist, tension, and advancement. When the image moves away from the target, pause before adding another correction.
01LocateFind the target and the direction it occupies in the image.
02OrientRotate the control body until lever deflection will act in the useful plane.
03DeflectUse the thumb to bring the distal tip toward the target.
04AdvanceMove forward only while the target remains controlled.
When the tip stops following the plan
Pause advancement. Identify whether the problem is thumb position, wrist orientation, insertion-cord tension, excessive input, or setup. Return to the last recognizable view, correct one input, and repeat the segment.
Room 05 · In the Studio
Pick it up before you ask it to perform.
Use the available flexible bronchoscope in the Studio. Hold the bronchoscope. Identify its parts. Connect what the hand does to what the distal tip and display show.
First encounter
Object orientation
Feel the handle, locate the controls, trace the insertion cord, inspect the distal tip, and identify the display relationship.
Then practice
The control path
Use the designated non-patient trainer to combine thumb, wrist, and light insertion-cord tension. Independent practice is acceptable; educator verification is optional.
When an error appears
Name it, correct it, repeat
Classify the problem as thumb, wrist, tension, or setup. Reset the affected segment and try again.
Before leaving
Reset for the next learner
Return the training system and simulator to the locally defined start state. This is not a substitute for manufacturer reprocessing guidance.
Station specification still required
Exact BFlex and Ambu models, displays, accessories, DeSim trainer and path, inspection and handling rules, start state, checkpoints, error thresholds, and reset sequence remain deferred to representative-station testing.
Room 06 · Choose the next work
Control first. Procedure next.
Repeat the station if the relationship among thumb, wrist, tension, and image is still effortful. Otherwise continue to the chapter that matches the clinical work ahead.

References and evidence boundary
The final page review will identify the one to three most influential sources supporting device-control instruction. Device-specific claims, ergonomic absolutes, legacy media, and performance standards remain unfrozen until evidence, equipment, and named clinical review are complete.
