For years A Step Ahead Prosthetics has been designing and fabricating socket interfaces for some of the world’s most advanced myoelectric prosthetic hands. However, in many cases the best and most practical solution lies in a combination of components, including body-powered hands and flexible materials (in place of the usual rigid sockets.)
The latest innovation out of our labs is a great example of A Step Ahead’s vision: Form follows function.
The main structure uses a carbon-graphite frame which is integrated seamlessly with a heavy-duty silicone palm. The frame offers the required rigidity to support the finger system while the palm includes our proprietary ASAP Oppositional Arch™ grip, which was designed to increase flexion force on finger system exponentially, in addition to creating a much more useful palm surface. Practical functionality without added complexities.
By combining a flexible silicone sleeve, molded directly from a 3D-scanned image of the residual limb, with custom rigid carbon parts this prosthesis provides firm anchoring points from which to engaged the multi-articulating finger system, while still allowing free movement of the wrist. A BOA® system, affixed to a carbon-graphite forearm suspension band, allows the patient to dial-in and control the exact amount of pre-tension needed for diverse tasks. The elastomer socket with incorporated axis-point works with the carbon-silicone palm grip maintaining a comfortable and confident fit.
