Above the knee post-operative residual limb support
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”).
1. An above-the-knee post-operative residual limb support assembly comprising:
a frame assembly comprising an upper frame and a lower frame, wherein the upper frame is configured to extend about at least a portion of a residual limb of a wearer, the lower frame is configured to receive an end of the residual limb, and the lower frame is coupled to the upper frame through a sliding connection such that upper frame and the lower frame are adjustable relative to one another in a linear manner;
a liner configured to be positioned between the frame assembly and the residual limb, the liner is configured to receive a distal end of the residual limb in a central compartment of the liner, the liner comprising a base material having an open top end and a closed distal end, wherein the closed distal end has a dome shape; and
a suspension assembly configured to support the above-the-knee post-operative residual limb support assembly on the wearer, wherein the suspension assembly comprises a waist belt and a vertical support coupled to the waist belt.
2. The above-the-knee post-operative residual limb support assembly of claim 1 , wherein the sliding connection comprises a first slot in the upper frame, a second slot in the lower frame, and a fastener extending through the first slot and the second slot, the first slot and the second slot defining a sliding axis.
3. The above-the-knee post-operative residual limb support assembly of claim 2 , wherein the fastener is an adjustable fastener that can be loosened to allow the upper frame and the lower frame to slide with respect to each other and tightened to secure the upper frame and the lower frame in place with respect to each other.
4. The above-the-knee post-operative residual limb support assembly of claim 1 , wherein the upper frame has a substantially T-shape.
5. The above-the-knee post-operative residual limb support assembly of claim 1 , wherein the lower frame has a substantially inverted Y-shape.
6. The above-the-knee post-operative residual limb support assembly of claim 1 , wherein a lower portion of the lower frame forms a bowl shape configured to receive a distal end of the liner.
7. The above-the-knee post-operative residual limb support assembly of claim 1 , wherein the liner is removably coupled to the frame assembly by a fastener.
8. The above-the-knee post-operative residual limb support assembly of claim 1 , wherein the base material of the liner comprises a flap portion that can bend between an open position and a closed position, wherein when the flap portion is in the open position, the residual limb can be inserted into the liner.
9. The above-the-knee post-operative residual limb support assembly of claim 8 , further comprising an outer wrap partially surrounding the liner and the frame assembly, the outer wrap being removably coupled to the frame assembly and the liner such that when the outer wrap is positioned on the above-the-knee post-operative residual limb support assembly, the flap portion is retained in the closed position.
10. The above-the-knee post-operative residual limb support assembly of claim 1 , wherein the vertical support is coupled to the upper frame.
11. The above-the-knee post-operative residual limb support assembly of claim 10 , wherein a length of the vertical support is adjustable through a tri-glide bracket.
12. A frame assembly configured to extend about at least a portion of a residual limb of a wearer, the frame assembly comprising:
an upper frame having a first slot;
a lower frame having a second slot; and
a first fastener extending through the first slot and the second slot, thereby coupling the upper frame to the lower frame, wherein the first fastener is adjustable such that the first fastener can be loosened to allow the upper frame and the lower frame to slide with respect to each other and tightened to secure the upper frame and the lower frame in place with respect to each other;
wherein the frame assembly is configured to be supported on the wearer by a suspension assembly, the suspension assembly comprising a waist belt and a vertical support coupled to the waist belt.
13. The frame assembly of claim 12 , wherein the first slot and the second slot define a sliding axis, and wherein the upper frame and the lower frame can slide along the sliding axis when the fastener is loosened.
14. The frame assembly of claim 12 , further comprising a second fastener extending through the first slot and the second slot.
15. The frame assembly of claim 12 , wherein the first fastener includes a threaded bolt extending through the first slot and the second slot and a threaded nut attached to the threaded bolt.
16. The frame assembly of claim 12 , wherein the upper frame has a substantially T-shape such that an upper portion of the upper frame is wider than a lower portion of the upper frame, wherein the lower portion of the upper frame includes the first slot.
17. The frame assembly of claim 16 , wherein the upper portion of the upper frame includes a hook-and-loop coupler configured to removably secure an inner liner to the upper frame.
18. The frame assembly of claim 12 , wherein the lower frame has a substantially inverted Y-shape such that an upper portion of the lower frame is narrower than a lower portion of the lower frame, wherein the lower portion is bent to form a bowl shape.
