Abstract
A prosthetic socket, comprising a base for distal connection means for attaching a prosthesis component to the prosthetic socket and comprising at least one side wall, which extends from the base in the proximal direction and at least partially extends around a stump to be held in the prosthetic socket, and at least one support for fastening the side wall to the base being arranged on the base.
Claims23
A prosthetic socket to receive an amputation stump, socket comprising:
- a base;
- two supports arranged on the base and extending medially and laterally from the base in a proximal direction;
- no more than two shell elements, each being attached directly to one of the two supports, each of the shell elements of the two shell elements being at least partially flexible, each shell element of the two shell elements are configured to enclose part of the stump, one of the shell elements of the two shell elements extending medially from the base on one of the two supports and one of the shell elements of the two shell elements extending laterally from the base on one of the two supports,
- wherein the two shell elements each comprise at least two different materials, and at least two of the at least two different materials have different thicknesses, the two shell elements each being more rigid in a region proximate the supports than regions of the two shell elements distant from the region proximate the supports;
- and
- a tensioning system arranged partially circumferentially and configured to act upon the two shell elements to compress the stump in at least a distal zone and a proximal zone of the socket, wherein the two shell elements are connectable in different positions, continuously or in predetermined positions, with the associated supports in a force-locking or form-locking manner to provide an adjustable length for the socket.

A prosthetic socket to receive an amputation stump, socket comprising:
- a base;
- first and second supports arranged on the base and extending medially and laterally from the base in a proximal direction;
- a first shell element connected directly to the first support and a second shell element connected directly to the second support, each shell element is configured to enclose part of the stump, the socket only comprises the first support and the second support, the first shell element extending medially from the base at the first support and the second shell element extending laterally from the base at the second support, wherein the first and second shell elements each comprise at least two different materials, and at least two of the at least two different materials have different thicknesses, the first and second shell elements each being more rigid in a region proximate the supports than regions of the first and second shell elements distant from the region proximate the supports;
- and
- a tensioning system arranged partially circumferentially on the shell elements to apply a force to the shell element, the shell elements configured to apply a compression force to the stump, wherein the shell elements are connectable in different positions, continuously or in predetermined positions, with the associated supports in a force-locking or form-locking manner to provide an adjustable length for the socket.
