Definitions

  • the invention relates to a prosthesis shaft with a proximal entry opening and a distal end or a distal end region and a fastening device for a prosthesis component arranged there, the prosthesis shaft having a frame made of a fiber-reinforced plastic with at least one free space and a method for its production.
  • Prostheses replace limbs or parts of limbs that are not or no longer present, whereby the prosthesis is intended to replace the shape and / or function of the natural limb as best as possible.
  • Different designs and technologies are known for attaching prostheses to the respective user.
  • a widespread possibility is the definition of prosthetic components, for example prosthetic joints and distal prosthetic components, over a prosthetic shaft that is applied to a stump.
  • a prosthesis liner can be arranged between the prosthesis socket, which can have a receptacle for a prosthesis joint or other component at its distal end, and the stump in order to reduce pressure, provide padding and, if necessary, a sealing effect within the scope of suction socket technology guarantee.
  • the prosthesis shafts are often designed as custom-made, dimensionally stable components made from fiber-reinforced plastics.
  • the fibers are usually high-strength inorganic or organic fibers such as carbon fibers, glass fibers or aramid fibers; thermoplastics or thermosets are used as the plastic matrix.
  • the distal end of such a prosthesis socket is often designed to be closed, so that the prosthesis socket extends completely around the stump.
  • such prosthetic sockets are comparatively heavy and only allow moisture to be removed to a limited extent.
  • frame sockets As an alternative to prosthesis sockets with closed walls, so-called frame sockets have been developed in order to reduce weight and to build up pressure or stiffening only in the necessary and suitable places.
  • frame shafts for example, a surface on a rear thigh can be recessed so that the shaft is formed onto the seat surface and the The prosthesis wearer does not sit on the hard prosthesis socket when sitting.
  • the frame shafts are mainly made of prepregs that cure under vacuum and heat, or are built up using the wet lamination technique.
  • Frame shafts usually have an inner shaft that is often made of thermoplastically deformable plastics. These materials are relatively heavy and thick and therefore require a large volume.
  • the inner shafts are airtight, which promotes sweating. This can cause skin irritation.
  • the object of the present invention is to provide a prosthesis socket and a method for producing a prosthesis socket with which it is possible to increase the wearing comfort of prosthesis sockets without reducing the functionality.
  • this object is achieved by a prosthesis shaft with the Merkma len of the main claim and a method with the features of the Maugeord Neten claim.
  • the prosthesis socket with a proximal entry opening and a distal end or a distal end area and a fastening device arranged there for a prosthesis component the prosthesis socket having a frame made of a fiber-reinforced plastic with at least one free space, provides that a textile is fixed to the frame that bridges the space.
  • the free space is formed in the wall of the prosthesis socket, whereby material of the dimensionally stable frame is saved. This reduces the weight of the prosthesis socket.
  • a textile is attached to the frame in order to at least partially cover or fill the free space and to at least reduce the area of the free space or the window.
  • the textile completely bridges the free space and completely covers it, so that the window is closed and a closed cross-section consisting of a frame, for example, is formed in this area of the prosthesis socket a fiber-reinforced plastic, and a textile attached to it over the entire lengthwise extension, so the entire distal-proximal extension of the prosthesis sschaftes results.
  • the free space can be designed as a window that is completely surrounded by the frame material.
  • the hard, dimensionally stable material of the frame for example frame pieces formed from prepregs or resin-impregnated glass fiber or carbon fiber blanks, are cut out, the cutouts and windows then being bridged by the textile and in particular completely getting closed.
  • the textile can be designed as a spacer knitted fabric, spacer knitted fabric or spacer fabric, which has the advantage that, in addition to air permeability, it provides a support and cushioning effect.
  • a knitted spacer fabric is able to enable a cushioning effect due to the support threads and a liquid transport due to the air permeability.
  • a further development of the invention provides that the textile is glued and / or baked to the frame.
  • the textile can, for example, be glued to the frame before the prepregs harden and held in place by the resin content of the prepregs.
  • the prosthesis socket with the glued-on textile components or the glued-on textile component is then heated with the application of a vacuum on an individual model of the residual limb or on a ready-made model, so that the frame elements harden and the textile is connected directly to the material of the frame. This saves work steps and provides a washable prosthesis socket with sufficient strength to be attached to a stump and to accommodate further prosthesis components.
  • a further development of the invention provides that the frame is formed from prepregs that are placed on the outside of the textile facing away from the user. This makes it possible that the sharp-edged edges of the frame, which can occur during the production and processing of fiber-reinforced composite materials, are not in direct contact with the user or with someone below. pulled liner, which reduces the risk of injury or damage to the liner can be avoided. In addition, ventilation and padding are still provided by the textile on the inside.
