3.4.4 Control Systems Fabrication
Definition: Fabrication of elements that provide suspension, load distribution, stability, range of motion and, potentially, terminal device function to the prosthesis/orthosis.
Code | Procedure | Description |
1 | Contouring components to positive model, structure, template or tracing | Any alterations done to componentry to prepare them for the prosthesis/orthosis (this can be internal or external).
|
2 | Thigh corset fabrication | Fabrication of external thigh section and attachment to articulated structural supports; includes making a pattern from measurements, fabricating with materials such as leather, thermoplastics, reinforcing materials, lacing, and straps. |
3 | Hip/Waist belt fabrication | Making pattern from measurements, and fabricating using materials such as leather and webbing. |
4 | Knee cuff fabrication | Making pattern from measurements and fabricating using materials such as leather and webbing. |
5 | Obturator door strap fabrication | Fabrication of obturator door straps with materials such as webbing and Velcro |
6 | Back check strap fabrication | Fabrication of back check strap with materials such as leather, webbing, Velcro and lacing. |
7 | Upper extremity control cable system fabrication | Fabrication of cable system to control and suspend prosthesis/orthosis and terminal device, using tracings and measurements. |
8 | Upper extremity suspension interface | Fabrication of suspension system for attachment to cable system or socket, using tracings and measurements e.g. cuff, harnessing straps. |
9 | Liner or pad fabrication | Any material (moulded or non-moulded) or combination of materials which provide an interface or pressure relief between the body and any part of the prosthesis/orthosis. |
10 | Strap fabrication | Usually attached to the structural interface or structural components for functions such as containment, suspension, and enhancement of joint function. |
11 | Tongue fabrication | Increases the surface area of the structural interface, usually a semi-rigid material is used. |
12 | Cover fabrication | Protecting or cosmetic coverings (usually soft or durable sewn materials) e.g. seating, joint covers. |
13 | Fabrication of external / internal build-up | Material added to the structural interface. |
14 | Machining components | Employing various methods to machine custom componentry. |
15 | Modifying manufactured components | Examples of modifications may include shortening materials/ sand blasting/ plastic coating/ extra holes, welding, use of epoxy. |
16 | Assembly of prefabricated kits/ components | Using prefabricated kits to create the prosthesis/ orthosis or part of prosthesis/orthosis e.g. dynamic hand orthosis, add-ons to seating or standing frame. |
