3.4.4 Control Systems Fabrication

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.
