Abstract
Technology is described for easy and safe attachment of a prosthetic limb to a percutaneous post that has been osseointegrated into the remnant limb of an individual with limb loss. A quick-disconnect device for a prosthetic limb can comprise a percutaneous post support assembly comprising a post locking assembly attached to a percutaneous post. A roller support can be coupled to the percutaneous post support assembly and can support torsional breakaway rollers. A release housing assembly can be coupled to the percutaneous post support assembly, and can comprise a limb support housing supporting a limb attachment structure to support a prosthetic limb. The release housing assembly comprises a torsional breakaway spring. The plurality of torsional breakaway rollers are each biased to the torsional breakaway spring to generate a spring force to restrict or limit rotation of the percutaneous post support assembly. Other breakaway springs and rollers are provided for bending release and axial release.
