Abstract
The present relates to an adjustable prosthetic limb socket system having a partial rigid support, a non-elastic, flexible support and adjustment means. The adjustable socket system of the present invention can be used for several types of amputations including transfemoral amputations, transtibial amputations, transhumeral amputations, transradial amputations, and other types of amputations. The present invention further includes kits having the adjustable prosthetic limb socket system, as well as methods of making the adjustable prosthetic limb socket system. Methods of using the socket system are further encompassed by the present invention.
Claims27
A socket system for the attachment of a prosthetic device to a residual limb of an individual, the residual limb having a circumference, and a surface area, wherein the socket comprises:
- a. a rigid support, wherein the rigid support is shaped to conform to at least a portion of the residual limb, the rigid support having rigid member and a distal base;
- b. a non-elastic, flexible support secured to the rigid support;
- and
- c. an adjustment means to maintain a volumetric fit of the residual limb, wherein the adjustment means is attached to the rigid support, the non-elastic flexible support, or both, and wherein the adjustment means provides adjustable circumferential force.
A socket for the attachment of a prosthetic device to a residual limb of an individual, the residual limb having a circumference, and a surface area, wherein the socket comprises:
- a. a rigid support, wherein the rigid support comprises a distal base and a rigid member that is shaped to conform to at least a portion of the residual limb wherein the rigid member covers at least about 180° of the circumference of the residual limb, thereby leaving a balance of the residual limb unsupported by the rigid support;
- b. a flexible support, secured to the rigid support, wherein the flexible support covers most or all of the balance of the residual limb and wherein the flexible support is made from a non-elastic material;
- and
- c. an adjustment means to maintain a volumetric fit of the residual limb, wherein the adjustment means is attached to the rigid support, the non-elastic flexible support, or both;
- and wherein the adjustment means adjusts to fit the circumference of the residual limb and provide circumferential forces for adequate hydrostatic weight bearing.
The socket of claim 11, further comprising an attachment for a prosthetic device, wherein the attachment is at the distal base of the rigid support.
A socket kit that comprises:
- a. a non-elastic, flexible support;
- b. an adjustment means to maintain a volumetric fit of the residual limb, and
- c. a rigid support.
A rigid support for use with socket for the attachment of a prosthetic device to a residual limb of an individual;
- the rigid support comprises:
- a. a distal base, wherein the distal base receives a distal end of the residual limb;
- and
- b. a rigid member that is shaped to conform to at least a portion of the residual limb wherein the rigid member covers between about 54° and about 270° of the circumference of the residual limb or between about 15% and 60% of the surface area of the residual limb.
