This cuff is part of the NIOP prosthetic modular arm catalog, and is used to fit transhumeral (above-elbow) amputees and people with limb difference. The (4) screw holes around the base of the perimeter align with the screw pattern on the Top Plate part from the NIOP Shelbow module https://www.thingiverse.com/thing:3639811
It is very effective, so it holds on without much constricting pressure, and the vertical supports allow the blood to still circulate. It also is well ventilated compared to fitted sockets. The socket is removable so it's easy to clean, and can be thermoformed again to adjust the fit as their stump shrinks.
The helix shape of the lacing constricts and compacts the arm in two directions, to grip it very securely, without slipping. If desired for extra grip, Dysem non-slip material can be added inside the cuff to eliminate the device from slipping, even when wet or sweaty.
The Helix Cuff is adjustable, so it can be worn shortly after surgery (2-3 weeks),
