An adjustable socket system includes first and second shell components and first and second longitudinal supports connected to a base. The socket system is movable between an open configuration to loosen the fit of the socket system, and a closed configuration to secure the fit of the socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point located and protected between the first shell component and the first support and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the socket system to the closed configuration.

An upper extremity post-operative residual limb support assembly includes an upper frame; a lower frame adjustably coupled to the upper frame; a liner coupled to the upper frame and the lower frame, the liner including: a first liner portion configured to be positioned adjacent the upper frame and extend at least partially about an arm of a user; and a second liner portion configured to be positioned adjacent the lower frame, the second liner portion including a closed end configured to receive a distal end of a residual portion of the arm.

An adaptive robotic finger prosthesis according to the inventive concepts includes a proximal phalanx body configured to be worn on a proximal phalanx portion of a cut finger, a middle phalanx body connected to the proximal phalanx body and configured to function as a middle phalanx portion of the cut finger, a distal phalanx body connected to the middle phalanx body and configured to function as a distal phalanx portion of the cut finger, a first proximal phalanx link disposed under the proximal phalanx body, a second proximal phalanx link disposed on the proximal phalanx body and joint-connected to the first proximal phalanx link, and a proximal phalanx elastic member provided at a joint between the first proximal phalanx link and the second proximal phalanx link to provide elastic force.

The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. In one embodiment, the assembly includes an eccentric metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A ring configured to receive a user's residual finger is disposed upon the articulation assembly, and may be adjusted to a target location based on a length of the residual finger. The articulation assembly is configured to utilize vertical movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-z plane, and the MCP pivot is configured to utilize lateral movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-y plane. Other embodiments are also disclosed.

A transtibial socket for a prosthetic lower limb includes a mesh arranged between rigid struts. The mesh includes a plurality of support members and a plurality of tensile members, optionally in combination with spacer members arranged between different support members. At least one tensioning member coupled with the tensile member extends through of past guides in the struts to an adjustable tensioning apparatus that is configured to allow the mesh to be constricted radially by the amputee-user. The mesh allows for the heat dissipation and volume adjustment, while increasing contact area and force distribution around a residual limb.

A post-operative support apparatus for a patient's transfemoral residual limb, includes: a planar, stretchable, tensionable and flexible wrap panel sized to wrap around an outer circumference of a patient's transfemoral residual limb, where the wrap panel includes first fastener(s) for maintaining the wrap panel in place around the patient's residual limb; a planar, stretchable, tensionable and flexible hip-band sized to wrap around an outer circumference of a patient's hip or waist, where the hip-band includes second fastener(s) for maintaining the hip-band in place around the patient's hip or waist; and third fastener(s) releasably fastening the wrap panel to the hip-band.

A prosthetic or orthotic device using at least one of measurements of residual limb length or circumference to define a prosthetic socket assembly configuration, comprising modular socket components fitted to the individual user's residual limb having a mounting point for an attachment, at least one compliant member attached to at least one stabilizing unit, and at least one second compliant member attached to at least one stabilizing unit wherein the first compliant member and the second compliant member work in cooperation with the stabilizing unit(s) to control bone position and support the limb within the interface.

An above-the-knee post-operative residual limb support device is described. The support device may be used shortly after amputation of a portion of a limb, such as a portion of a patient's leg (e.g., such as in an above-the knee (AK) amputation procedure). Such a support device may be referred to as an Immediate Post-Operative Prosthesis (IPOP).

A prosthetic apparatus and system for a trans-tibial amputee consisting of a post-operative interface socket that can be adjusted to accommodate the size of an amputated limb and changes in size of the limb. The prosthetic apparatus includes a lower socket into which the post-operative socket can be inserted, the lower socket being adjustable for changes in size of the post-operative interface socket. The post-operative socket also has a removable upper back shell that immobilizes movement of the knee during an initial recovery phase but can be removed to allow the knee of the amputee to flex.

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.
