156B Week 3

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Finalize shaft design for insertion tube

  • Building and testing of two new designs for angulation wires

Accomplishments from Previous Week

• • Design of shaft system

  • Printed a model for angulation wire design to be tested

  • Came up with two angulation wire control designs

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Build shaft system to scale of the insertion tube (Matt)

  • Create CAD model of alternative design that has pulley system in control body (Mark, Gio)

  • 3D print and test the prototype of the sliding sprocket design (Eric)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Determine if only a shaft can be used as a pulley mechanism to change the tension. To address this, a prototype of an approximately 6mm outer 

  • Utilizing a pin index system for alignment during reattachment ("D"-shaped top of insertion tube)

  • Can now work within 7 mm diameter of insertion tube

  • The team will be brought to the Simlab for demonstrations

  • First create a hollow tube so other channels can be accommodated later

  • Suggested plan:

    1. Make a hollow tube 7mm*

    2. Make it maneuverable, detachable*

    3. Fitting camera (Somal will take care of)

    4. Vacuum

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Concern for other channels with pulley system within insertion tube (in person, 4/9)

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • Have we received a bronchoscope device (in person, 4/9)

Risks and Areas of Concern

• • Accommodating the other channels (vacuum, light, camera)

  • Small diameter insertion tube may not fit the shaft, still testing

Resources or Information Required but not Available

• • Bronchoscope device 

Schedule

• • Describe upcoming milestone

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • Amount spent: $91

  • Amount remaining: $1409
