This project entails the construction of a functional larynx model for educational purposes. The model is to be automated and demonstrate laryngeal dynamics with proper anatomical consideration.
Problem Statement:
The goal of this project is to continue the development of a physical 3D laryngeal model with moving laryngeal cartilage, membranes and muscles. We would like to demonstrate nerve-muscle action and interaction in the larynx for voice production. The model is to be used as a patient educational tool for improved understanding of the laryngeal mechanism. It will also be used to plan treatment based on diagnosis of voice, airway and/or swallowing disorder. This semester, we will design a prototype that accurately demonstrates a healthy laryngeal muscle movements. In the subsequent semester, we would like to introduce several laryngeal disorders into the model.
Currently, a new model has been ordered from our client and animation of the incoming model is under consideration.
| Week | Reporting Period Beginning | Activities |
|---|---|---|
| 1 | September 5 | Developed team structure with organizational roles; contacted the client to set up a meeting. |
| 2 | September 12 | Researched background on the larynx; acquired prototype from previous semester; met with client and clarified project objectives. |
| 3 | September 19 | Developed PDS as a living document; read over previous teams final report and presentation |
| 4 | September 26 | Brainstormed arytenoid cartilage movement; dissembled old prototype; scheduled regular meeting time. |
| 5 | October 3 | Proposed and contacted client about obtaining a new larynx model; updated PDS; assigned slides for the midsemester presentation. |
| 6 | October 10 | Proposal for new model accepted by client; developed and rehearsed power point presentation |
| 7 | October 17 | Received new model from client and began prototyping work immediately |
| 8 | October 24 | Began mechanical work on arytenoid cartilage motion and contacted Greg Gion about creating artificial muscle tissue |
| 9 | October 31 | Milled track for arytenoid cartilage motion and created sliding stock to translate and rotate arytenoid cartilage |
| 10 | November 7 | Further improved arytenoid cartilage track and assembled the parts |
| 11 | November 14 | Purchased necessary materials, created a box to mount the prototype and spoke with medical artist Greg Gion about creating artificial muscle tissue |
| 12 | November 21 | Assembled prototype, began construction on electrical automation and planned the rest of the semester |
| 13 | November 28 | Finished prototype, attached muscles, implemented movements, worked on poster and presented final design |
