The device is designed in a way that can be manufactured locally in Low- and Middle-Income Countries (LMICs) using conventional manufacturing techniques, i.e. turning and milling. However, making a standard medical device using these techniques needs highly skilled operators which may increase the labor cost and lack of it results in producing low-quality parts. Therefore, a jig-based manufacturing kit (image below) has been developed at Imperial College London.
List of the items in the kit are as follows:
- Large clamp primary jig and pins
- Large clamp secondary jig and pin
- Small clamp jig and pins
- 3/16 Dia centre drill
- 5/16 Dia centre drill
- 4.8mm drill bit
- 8.5mm drill bit
- 12.5mm drill bit
- 4.5mm slot drill
- 13mm 3-flute carbide slot drill
- 5mm reamer
- 12.8 reamer
- Parting blade HSS-Co8 2x13x110mm
- 100mm Dia x 2mm width course pitch slitting saw
- Slitting saw arbor
- Combi flap wheel P120 grit
- P40 grit sandpaper
In addition to the tools listed above, basic lathe tools for turning and chamfering Aluminum are also required.
Aluminium 6xxx, such as 6061-T6 or 6082-T6 round bars with 1.5 and 1 inch diameters for large and small clamps, respectively, are required. For the rod, Stainless steel 304 tube with wall thickness 3/64 inch (1.19mm) is recommended.
