Prosthetic adapter module

A prosthetic adapter module configured to be attached, by a predetermined number of screws, to a socket member of a prosthetic sleeve, into which sleeve an amputation stump of a prosthesis user is to be inserted, the adapter module comprising:

• a disc-shaped connection washer having a central axis, and
• a module body provided with a washer space structured to provide room for the disc-shaped connection washer,
• the washer space having an extension to provide for movement of the disc-shaped connection washer within a plane essentially perpendicular to a longitudinal axis of said prosthetic sleeve prior to the disc-shaped connection washer being fixated in a determined position,
• the disc-shaped connection washer having an interior surface defining a through hole for receiving a washer attachment screw such that the screw essentially extends along said longitudinal axis,
• the through hole having a central axis centered with respect to the interior surface of the connection washer that defines the through hole,
• the central axis of the through hole being positioned off-center in relation to the central axis of the disc-shaped connection washer in order to maximize lateral movement of the disc-shaped connection washer in all directions within the plane,
• the module body being provided with a first side structured to face the socket member, and a second side at the other side of the module body, and
• the first side being provided with a first side opening to the washer space having a size such that the disc-shaped connection washer may enter the washer space via the first side opening.
