Materials
All materials (except cadaver head) can be purchased at home improvement stores such as Home Depot or Lowe's for under $20.
Assembly
Assembly
Base
Base
One Base can be used for multiple cadaver head units.
Two support boards are glued to the ends of the larger base board.
Mounting holes are created.
The 1-in thick boards with mounting holes drilled into them are secured to the base board with wood screws.
The ADS PolyFlex Pipe is secured using hex bolts and nuts.
The angle of the spine-mimicking pipe can be adjusted and secured with the bolt/nut, or it could be left floating to have variable angle depending on its application.
CAP and NECK
CAP and NECK
Each cadaver head will have its own Cap and Neck.
Note: Pilot holes may need to be drilled into the PVC and vertebral body for the wood screws to follow.
The PVC cap is attached to the vertebral body of the cadaver head via three wood screws.
Then the PVC tube representing the neck is fitted into the cap and secured with another wood screw.
This is one cadaver head-cap-neck unit.
The head-cap-neck assembly then slides onto the ADS pipe to create the fully functional simulator.
To improve visibility and make it easier to secure the Cap to the vertebral body of the cadaver head, we designed a new Cap out of plexiglass.
CAP (New Design) and NECK
CAP (New Design) and NECK
Each cadaver head will have its own Cap and Neck.
To improve visibility and make it easier to secure the Cap to the vertebral body of the cadaver head, we designed a new Cap out of plexiglass
This is the new plexiglass Cap.
Plexiglass discs were glued together to make a new Cap.
This Cap is also affixed to the vertebrae with wood screws. The transparent cap makes it much easier to see where the vertebrae is.
The PVC Neck is then attached to the Cap by three set screws.
The whole head unit then slides onto the Base to complete the simulator.
