3. Background Procedure looks at: Probe requires fine motor control
Vocal cords
Larynx
Other throat structures
Probe requires fine motor control

4. Background (cont.) Sensitive regions in nasal passage and larynx
Turbinates
“No-touch” structures
No widespread use of training model

5. Problem Statement Model must: Be anatomically correct
Use materials with life-like textures
Provide user feedback when mistakes occur
Not damage endoscope
                                          

6. Current Design Plastic mannequin shell Foam support cross- sections
CT data
MIMICS
Turbinates – air-filled bladders
“No-touch” - microswitches

7. Current Design (cont.) Key problems: Microswitch sensitivity
Turbinate system complexity
Aesthetics

8. Design Improvements One feedback system Piezoelectric film
Comparator – thresholds
Indicator lights
Force
= electron

9. Design Improvements (cont.)
Physical appearance
Movable stand
Aesthetics

10. Clinical Implementation
Questionnaire (1-10 rating)
Anatomical correctness
Educational value
Ergonomics
Tactile sensation
10 Experienced clinicians
2-5 Medical students

11. Future Work Implement improvements Have clinicians/students test model
Patent consideration
