Abstract
A transradial prosthesis assessment system apparatus and method for simulating and evaluating alignment and functionality of a definitive prosthesis system for a user's diagnostic socket is provided. The apparatus includes socket adaptors, a connector, shaft housings of different sizes, extension shafts of different lengths and wrist adaptors that can be connected through different combinations to provide length and alignment adjustability to emulate the definitive prosthesis.
Claims19
A transradial prosthesis assessment apparatus for simulating and evaluating alignment and functionality of a definitive prosthesis system for a user's diagnostic socket, the apparatus comprising:
- a plurality of socket adaptors configured to be compatible with diagnostic sockets;
- a connector for housing a socket adaptor of the plurality of socket adaptors, wherein the socket adaptor is configured for axial rotation within the connector to enable alignment adjustments;
- a plurality of different shaft housings of different sizes, wherein a shaft housing of the plurality of shaft housings is configured to connect to the connector at a hinge joint that allows for uniplanar rotation to enable alignment adjustments;
- a plurality of different extension shafts of different lengths, wherein a fastener can secure an extension shaft of the plurality of extension shafts within the shaft housing of the plurality of shaft housings for stability;
- a plurality of wrist adaptors, wherein a wrist adaptor of the plurality of wrist adaptors can attach to the extension shaft;
- and
- wherein different combinations of the plurality of shaft housings and the plurality of extension shafts result in different lengths in a range between 85 mm and 260 mm.
An adjustable transradial prosthesis assessment apparatus for simulating and evaluating alignment and functionality of a definitive prosthesis system for a user's diagnostic socket, the apparatus comprising:
- a socket adaptor configured to connect to a user's diagnostic socket, wherein the socket adaptor is selected from a plurality of socket adaptors each configured to be compatible with diagnostic sockets;
- a connector for housing the socket adaptor, wherein the socket adaptor is configured for axial rotation within the connector to enable alignment adjustments;
- a shaft housing connected to the connector at a hinge joint that allows for uniplanar rotation to enable alignment adjustments, wherein the shaft housing is selected from a plurality of different shaft housings of different sizes;
- an extension shaft, wherein the extension shaft is selected from a plurality of extension shafts of different lengths, wherein a fastener secures the extension shaft to the shaft housing for stability;
- and
- a wrist adaptor attached to the extension shaft;
- wherein the shaft housing together and the extension shaft provide an adjustable length of the apparatus between a range of 85 mm and 260 mm.
A method for an adjustable transradial prosthesis assessment apparatus for simulating and evaluating alignment and functionality of a definitive prosthesis system for a user's diagnostic socket, the method comprising:
- selecting a socket adaptor from a plurality of socket adaptors each configured to be compatible with diagnostic sockets, wherein a connector is configured for housing the socket adaptor, wherein the socket adaptor is configured for axial rotation within the connector to enable alignment adjustment;
- selecting a shaft housing from a plurality of different shaft housings of different sizes, the shaft housing configured to connect to the connector at a hinge joint that allows for uniplanar rotation to enable alignment adjustments;
- selecting an extension shaft from a plurality of extension shafts of different lengths, wherein a fastener secures the extension shaft to the shaft housing for stability;
- and
- selecting a wrist adaptor from a plurality of wrist adaptors, the wrist adaptor configured to attach to the extension shaft;
- wherein the shaft housing together and the extension shaft provide an adjustable length of the apparatus between a range of 85 mm and 260 mm.
