#2284: SpringLimb

Today’s invention is an alternative prosthetic limb attachment.

A user would have ferrous discs screwed into the bone of the affected limb (red). The tissue would heal over, lessening the risk of infection, when compared eg to titanium rods which protrude through the skin.


A close fitting ‘boot’ would encase the stump…but much less tightly than conventional equipment which often restricts air movement to the skin.

The boot would be slipped on over the stump. A motorised screw device would then be used to insert these magnets (blue) into locations in the boot walls, under control to avoid bruising.

In use, the stump would be held firmly in an equilibruim position.

A small amount of springy, vertical movement provided by the magnetic field would add to the comfort of wearing it.
