Abstract
An adjustable socket system includes a base, longitudinal supports connected to the base and extending along a longitudinal axis, and shell components operatively connected to the longitudinal supports and defining a receiving volume adapted to receive a residual limb. The adjustable socket system is radially expandable between open and closed configurations. The shell components include a first shell component having distal and proximal parts that are longitudinally displaceable with respect to one another such that a length of the first shell component is adjustable between a first length and a second length different than the first length.
Claims10
An adjustable socket system comprising:
- a base;
- a plurality of longitudinal supports connected to the base and extending along a longitudinal axis of the adjustable socket system;
- and
- a plurality of shell components operatively connected to the plurality of longitudinal supports and at least in part defining a receiving volume adapted to receive a residual limb, the adjustable socket system movable between an open configuration in which at least one of the plurality of shell components is moved radially outward relative to the longitudinal axis to loosen a fit of the adjustable socket system, and a closed configuration in which at least one of the plurality of shell components is moved radially inward relative to the open configuration to secure the fit of the adjustable socket system on the residual limb;
- wherein a first shell component of the plurality of shell components includes distal and proximal parts that are longitudinally displaceable with respect to one another along a length of a first longitudinal support of the plurality of longitudinal supports so that a length of a continuous contact surface of the first shell component is adjustable between a first length and a second length different than the first length such that the first shell component is arranged to continuously engage the residual limb in both the first and second lengths;
- wherein overlap is defined between the distal and proximal parts along the first longitudinal support in a longitudinally-oriented direction, a length of the overlap increases or decreases as at least one of the distal and proximal parts is displaced along the first longitudinal support while maintaining the continuous contact surface, with surfaces of the distal and proximal parts slidably engaging one another as said overlap is increased or decreased.
