Modular prosthetic sockets and methods for making same

摘要

The invention relates to a prosthetic socket for a residual limb of the lower extremity or upper extremity of an individual person. The residual limb has particular dimensions and anatomical contours; the prosthetic socket has dimensions and contours that fit the dimensions and contours of the residual limb. The prosthetic socket may also fit in a manner that is biomechanically particularly appropriate for the individual. The prosthetic socket is an assembly of components from groups of components that include (a) struts arranged longitudinally with respect to the residual limb, (b) proximal brim members arranged proximally to the struts and connected thereto; and (c) distal socket members disposed at the distal base of the prosthetic socket. The socket components within these groups may be modular in that they can vary with respect to dimensions and/or contours, and yet have common connecting features that permit assembly of the components together to form the prosthetic socket.

主权项

1. A modular prosthetic socket for a residual limb of a lower extremity of a patient, the modular prosthetic socket comprising:
four longitudinal struts arranged longitudinally with respect to the residual limb, each strut having a distal portion and a proximal end; a distal attachment member coupled with the distal portions of the four struts, wherein the distal portion of each of the four struts is adjustable in an angle by which it is mounted to the distal attachment member, and wherein the distal attachment member comprises;
a distal component comprising a first serrated channel;a proximal component attached to the distal component to form the distal attachment member, wherein the proximal component comprises a second serrated channel, and wherein the first serrated channel and the second serrated channel are configured to be joined together when the distal component is attached to the proximal component, in order receive the distal portions of the four struts and attach them to the distal attachment member; anda moisture evacuation channel extending through the distal component and the proximal component; and four proximal brim members, each of which is coupled with a separate one of the proximal ends of the four struts.
