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 device for a lower extremity residual limb of a patient, the device comprising:
a distal attachment member; four longitudinal struts, each of the struts having a distal end and a proximal end, and each of the struts connected at its distal end to the distal attachment member; a cross-link member fixed to and connected between two of the four longitudinal struts; a proximal brim member comprising an adjustable encircling band fitted over the proximal ends of the four longitudinal struts; and an ischial seat extension coupled with the proximal end of one of the four longitudinal struts, wherein the ischial seat extension is configured to bear weight by fitting under an ischial tuberosity of the patient.
