Abstract
A prosthetic insert unit for cushioning shocks in prosthetics is provided. The unit includes attachment member (,etc.), a lower sleeve (,′ etc), a slide bearing (,′ etc.) to allow free reciprocal motion therebetween, an elastomeric energy storage member (,′ etc.) received in the interior of the sleeve (,′ etc.), a piston (,′ etc.) cooperative with said elastomer member to compress same, and an anti-rotation mechanism. Preferably, the anti-rotation mechanism is integral with the slide bearing (,′ etc.). The elastomer member provides controlled deflection as well as damping for the insert. Preferably, an anti-click element (,etc.) is provide to minimize rebound clicking. Acoustical elements (,etc.) may also be included to minimize noise transmission into other areas of the insert.
