Definitions

  • This invention relates to the general field of aids to prosthetic limbs, and more specifically to a diagnostic liner system enabling the optimal measurement and fitting of prosthetic sockets used for the eventual permanent fitting of definitive prosthetic limb sockets.
  • a prosthetic check socket is a temporary socket used to determine the optimal fit and dynamic alignment for an amputee's definitive socket. As a residual limb heals, its volume and configuration can change drastically. Multiple assessments are often required to determine optimal fit of a check socket before the definitive prosthetic socket is made.
  • An artificial limb has several parts, the components which are purchased from the manufacturers and the socket which is designed and manufactured by the prosthetist.
  • the socket is the part that interfaces with the body, and transfers the weight of the person through to the components.
  • the components are everything attaching to an adapter plate under the socket such as the prosthetic knee, leg, or foot.
  • a prosthetist When fitting a new prosthesis, a prosthetist first completes what is called a check socket, or diagnostic socket. It is a clear thermoplastic "prototype” that is used to determine the fit before continuing on to more expensive materials. It is also a see-through and heat moldable material, so changes can be made as needed before going on to the "definitive" socket.
  • liners with surface variations such as rings or other features devised so that liner will grip the inside of the socket and provide appropriate cushion and ventilation. These features are not intended to be used to diagnose or fit a check socket, and therefore are not optimal solutions.
  • Another method is the use of liners embedded with electronic pressure sensors or with materials able to detect and display specific pressures by means of color changes. The first method requires specialized electronic equipment to interpret and localize the pressure readings, and the second method is not reusable. Both methods are not optimal given the global need for accurate inexpensive prosthetic limb fittings.
  • An even more specialized and expensive solution is the use of 3D laser scanning of the residual limb in order to 3D print a check socket.
  • the disclosed diagnostic liner system is designed to provide visual and quantifiable assessment of check socket fit. It is easier to use than prior art solutions, less expensive, and reusable.
  • the diagnostic liner is pulled over the generic liner, and fits inside the check socket.
  • the diagnostic liner is a thin prosthetic sheath that has silicone or gel compressible elements that allow the prosthetist to see exactly how much pressure is being applied over all surface areas of the residual limb.
  • the diagnostic liner system provides a quantitative evaluation of the fit of the check socket, so that the prosthetist can design a definitive socket that fits comfortably, securely, and prevents pressure sores, residual limb degradation and prosthetic instabilities.
  • the invention provides a diagnostic liner system for visual assessment of prosthetic limb socket fit, comprising a diagnostic sheath that fits within a check socket, the sheath having a surface with an array of compressible elements that are compressed within the check socket in proportion to pressure exerted on areas of the sheath by areas of a residual limb inserted into the check socket.
  • a transparent test socket can be used as the check socket.
  • the invention will work also if a definitive socket on a prosthetic limb is used as the check socket.
  • the sheath can likewise be specific to the diagnostic phase and additional to a generic liner, but a functional equivalent would be to have the compressible elements are embodied directly into a generic liner as the sheath.
  • the array of compressible elements comprises projections of a regular geometric shape; b) the check socket is transparent and an extent of compression of the compressible elements is visible through the check socket; c) the compressible elements are made of elastomeric material that compresses when stressed, and retains a resulting shape when a compression force is released;
  • the invention also discloses a method for visual assessment of prosthetic limb socket fit, using a diagnostic sheath that fits within a check socket, the sheath having a surface with an array of compressible elements that are compressed within the check socket in proportion to pressure exerted on areas of the sheath by areas of a residual limb inserted into the prosthetic limb socket to detect specific areas of the check socket that create too great or too little pressure on the residual limb.
  • the compressed element pattern is used by a prosthetist to quantify a shape of a deformity by visibly marking the compressed element pattern onto an outside surface of the check socket.
  • the check socket is transparent, and the prothetist visually checks for areas of noticeable compression of the compressible elements. Compressed projections forming the compressible elements are measured, compression of the compressible elements is accurately characterized in detail, and requisite adjustment information is marked on the check socket for later adjustment of the check socket.
  • the check socket is reshaped by referring to the corrective information provided by the diagnostic sheath and its compressed elements for correct shape to fit a residual limb and the check socket is then used as a template for a definitive (final) socket.
  • a luminescent dye used in the compressible elements can be illuminated with a black light. A visual check is then made of the diagnostic sheath within otherwise opaque laminations of a even the definitive socket, and calibrations and fine adjustments are made to the definitive socket.

  • Fig. 3b shows a raised area 42 on a residual limb 14.
  • Fig. 3c shows a simplified version of the grid 28 area in Fig. 3a in order to illustrate the effect of the raised area 42 as it compresses the grid 28 against the inside surface of the check socket 24. Note: the transparent check socket 24 is assumed to be in a plane covering, but not obscuring the elements of Figs. 3a-c & 5a & 5c. (see Figs. 5b & 5d) Fig.
  • 3d shows compressed elements 34 (walls) of the grid 28 caused by the raised area 42 (hatched ellipse), and how the extent of compression 36 would be measurable through the check socket 24.
  • the raised area 42 signifies a part of the residual limb 14 which exerts unwanted pressure on the check socket 24 in spite of the use of a generic liner 16.

  • the diagnostic liner system 10 will now be described in detail, beginning with the preferred embodiment, the grid compression implementation, and then an alternate embodiment, the projection compression implementation.
  • the grid compression implementation employs a diagnostic liner 10 as shown in Fig. 2 which is able to detect and quantify a raised area 42 as illustrated in Fig. 3d.
  • the walls 30 of the grid 28 are compressed by the raised area 42 pressing the diagnostic liner 10 into the inside of the check socket 24 as indicated by the compressed element 34 which is visible through the wall of a check socket 24.
  • the compressed element 34 pattern created by a raised area 42 can allow the prosthetist to quantify the shape and height of the underlying deformity by visibly marking the compressed element 34 pattern onto the outside of the check socket 24.
  • the thermoplastic check socket 24 can then be reshaped by a heat gun by referring to the corrective information provided by the diagnostic liner 10.
  • a check socket 24 can be tailored precisely to fit the unique shape of an amputee's residual limb 14.
  • the diagnostic liner 10 may be worn over, or may take the place of the generic liner 16 during the fitting analysis, depending on its chosen thickness. It is conceivable that a selection of diagnostic liners 10 of graduated thicknesses will be employed. The prosthetist should select a diagnostic liner 10 thick enough so that the majority of its grid 30 surface is in equal contact with the inside of the check socket 24, but not so thick that only compressed elements 34 are detectable. At the end of the diagnostic fittings and check socket 24 adjustments, the diagnostic liner 10 should contact all areas of the inside of the check socket 24 equally and without undue compression 36.
  • the projection compression implementation employs a diagnostic liner 10 as shown in Fig. 4 with an array 40 of projections 32 (hemispherical nubs) on its sheath 26.
  • Figs. 5a & 5b when the diagnostic liner 10 is in equal contact with the check socket 24, only the zenith of each projection 32 is in contact with its inner surface.
  • Figs. 5c & 5d show how a raised area 42 of the residual limb 14 causes noticeable compression 36 of the top of nearby projections 32 which provide a visual indication through the transparent check socket 24 of an area of greater pressure.
  • a diagnostic protocol comparable to the grid implementation would include measuring the diameter of the compression 36 of projections 32 as well as displacement from the center-point of each projection 32 if apparent.
  • the raised area 42 would then be accurately characterized in detail, and this information could be visibly marked on the check socket 24 for adjustment as described above.
  • the density, distances between, and size of the diagnostic elements namely grid walls 30 or nub projections 32, would be determined by the object of providing the most accurate and useable information for the prosthetist. If the grid 28 is too dense, its walls 30 will not splay sufficiently to be measurable through the check socket 24. If the grid 28 is too wide, it cannot provide enough information for an optimal fit. If the walls 30 are too thin, they cannot show sufficient compression 36. If the projections 32 are too few or too small, an optimal fit is not possible, whereas if they are too large or too close together, they cannot provide useful information because their compression may not be detectable.
  • the density and malleability of the material used to construct the diagnostic liner 10 will also play a part in determining the physical parameters of its surface features.
  • the grid walls 30 are 1 centimeter (cm) wide, 3 cm apart, and 2 - 5 mm above the 1 mm thick sheath 26, whereas projection nubs 32 are 1 cm in diameter, 3 cm apart and 2 - 5 mm above the 1 mm thick sheath 26.
  • Figs. 2 & 4 show a cylindrical shape of the liner 10, alternate liner shapes, including a cone like geometry or combinations thereof, are claimed as part of the invention. Application research will determine the appropriate shape required to provide optimal check socket 24 fitting.
  • grid compression implementation examples include a grid 28 comprised of interconnecting shapes of any appropriate geometry, such as triangles, pentagons, hexagons, etc.
  • projection compression implementation can include any shape of projection 32 that provides equivalent outcomes such as 3 or 4 sided pyramids, small spheres attached to a supporting substructure, flattened cones, etc.
  • the diagnostic liner and method 10 could also be employed as an upper limb prosthetic check socket fitting tool.
  • the diagnostic liner 10 will be preferably made from silicone or gel like material. Silicone has the unique property that it does one "creep" when stressed, and retains its shape when compressed and released. Other materials of similar properties or capable of achieving equivalent objects are being investigated and may be utilized.
  • the sheath 26 can be made from the same material, and the entire diagnostic liner 10 may be bonded together in several stages or molded as a complete unit. Alternately, the sheath 26 may be made from a generic liner 16 material, and either grid 28 or projections 32 would be embedded into or formed onto its surface.
  • the top surface of the diagnostic liner 10 may be formed from a less sticky material than silicone so that it can be properly inserted into the check socket 24.
  • a lubricant spray may be required to ensure proper pre-diagnostic alignment of the grid 28 or projections 32 within the check socket 24.
  • an additional embodiment of the disclosed invention incorporates a liner sock inside the novel diagnostic liner mesh.
  • Liner socks are used to allow easy fitting of a socket onto the limb by providing a low friction surface such as nylon or similar fabric. By this means the liner sock is fitted over one's residual limb and then the check socket (or diagnostic liner) can be easily fitted without abrasion to the residual limb.
  • This embodiment provides for the low friction liner sock to be made together with the diagnostic liner as one unit. By this means the diagnostic liner can be fitted over the residual limb with ease and then the check socket may be properly fitted by analyzing the deformation of the diagnostic liner.
  • Another embodiment includes the addition of fluorescent, luminescent, phosphorescent or equivalent dyes into the elastomeric material (silicone gel or equivalent) during the manufacturing of a diagnostic liner.
  • Fluorescent silicone or similar products can glow if illuminated by a black light.
  • the definitive (or final) socket is made using the diagnostic socket as a template by laminating with fabric and resin which makes it stronger and lighter, but is also not transparent under normal conditions.
  • a fluorescent diagnostic liner By using a fluorescent diagnostic liner and by illuminating the definitive socket with a black light, the diagnostician can observe visible distortion of the silicone liner through the socket normally opaque laminations. By this means, a fluorescent diagnostic liner can be used to calibrate the correct fitting of both check and definitive sockets.
