Overview of Status of Analysis, Design, Fabrication, Tests, etc
Determined the approximate force needed to angulate insertion tube's distal tip
Doing a more in-depth analysis of magnetic pulley mechanisms to determine if the tension of the angulation wires can be controlled
Analyzing hooking mechanisms and designs as a method to control the angulation wires
Designing and fabricating a prototype that uses a hex fitting to rotate a pulley mechanism inside the insertion tube and therefore changing the tension to control the distal tip
Accomplishments from Previous Week
In the previous week, the initial design of using a magnetic pulley system was analyzed for its feasibility. Designs were discussed by the team to begin building a simple prototype of a mechanism that can control the distal tip of the bronchoscope.
We narrowed down the scope of the project by focusing directly on a detachment mechanism and control of the distal tip
Researched additional disconnect/connect methods to pursue
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Complete the prototype of the hex design to determine the maneuverability of the distal tip (Matt)
Continue working on the original flex bronchoscope design (Matt)
Brainstorming various hook ideas for detachment mechanism, and determining which are feasible (Gio)
Model connector mechanisms that illustrate how the four channels of the bronchoscope are organized (Mark)
Create a model of how the angulation wires will be controlled inside the control body using a magnetic and mechanical connection (Eric)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Only need to focus on:
Detachment/reattachment mechanism (in person, 3/23)
Maintaining tension of angulation wires (in person, 3/23)
Look into hook designs (in person, 3/23)
Using a "pin" mechanism to ensure whatever connects the angulation wires to the control body will remain in place after re-attachment (3/16)
Look into two types of motors that can be implemented in our project: ultrasonic and homopolar (3/16)
AMBU (medical devices provider) - See if we have the ability to obtain samples (3/16)
Think about how to disinfect bronchoscope if purchased from Ebay. (3/16)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate the date of comments and if via email or in person)
Professor Talke's previous sponsored team built vertebrae section in a distal tip of the insertion tube and we can follow something similar (in person, 3/20)
Comments from Other Students in the Class (indicate the date of comments and if via email or in person)
A student during our risk reduction presentation commented on if we built a bronchoscope and also discussed a potential website for used parts for medical devices that we can find an inexpensive bronchoscope device.
Risks and Areas of Concern
Insertion tube has a small diameter that causes a difficult workspace
The difficulty of obtaining a bronchoscope device to take apart
Ensuring that device remains will be functioning after re-attachment.
What materials to use?
Resources or Information Required but not Available
Physical bronchoscope
Interior dimensions/specs

Progress on Report and Webpage
The report has not yet been started however photographs and models are being kept to be documented in the future. The webpage is being updated with the models as the project progresses.
