Artificial limb casing and method for the production thereof

The invention relates to an artificial limb casing (1) having an insertion opening (4) for inserting the artificial limb, wherein a joint area (3) to which an end area (2) is integrally connected is formed on the casing (1). The invention further relates to a method for producing an artificial limb casing (1), wherein a textile intermediate layer (8) is applied to the outside of a hollow polyurethane substrate (9), and a silicone layer (7) is applied to the textile intermediate layer. The casing (1) is made of an elastomer material that has a lower Shore hardness in the joint area (3) than in the end area (2).

STRUCTURE COMPRISING STACKABLE LAYERS

A structure assembled by first and second stackable layers having properties allowing for the first and second stackable layers to be shaped into at least first and second different shapes, and at least one fastener to releasably secure the first and second stackable layers together in one of the at least first and second shapes in a semi-rigid or rigid, and unitary construction. The first and second stackable layers are secured into one of the at least first and second shapes by the at least one fastener to form a semi-rigid or rigid, and unitary construction.

FLEXIBLE INNER SOCKET FOR PROVIDING INNER CIRCUMFERENCE REDUCTION TO RIGID PROSTHETIC SOCKET
20240261118 · 2024-08-08 ·

A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

Methods for bone stabilization

A compression stabilized prosthetic device for a patient having an amputated limb includes a first socket portion for contacting a patient's limb, and a second portion for the attachment of a prosthetic component. The first socket portion has compression portions configured for compressing portions of the patient's limb, and relief portions for receiving other portions of the patient's limb which bulge upon the compression applied by the compression portions. The relief portions may be formed as openings or as enlarged radius portions of the first socket portion.

Liner for prosthetic and orthopedic systems

A liner is arranged for use in prosthetic and orthopedic devices. The liner defines first and second end portions, and inner and outer surfaces. The liner includes an inner layer having a frictional component and forms at least part of the periphery of the inner liner surface. The inner layer defines a plurality of apertures. A porous element is in communication with the inner liner surface and is connected to the inner layer such that the apertures permit a transfer of air from the inner surface to the porous element. A base layer adjoins the porous element and extends between the first and second end portions of the liner.

MODULAR LOWER LIMB PROSTHESIS SYSTEM
20180289511 · 2018-10-11 ·

A lower limb modular prosthetic system that may be fabricated by a 3D printer capable of printing with composite fiber filament, nylon, or metal. The production process may include a 3D printer that is capable of routing fiber in specifically programmed patterns. The components of the prosthetic system may be designed for direct patient end-use, and may be energy returning in nature.

Orthosis, orthosis or prosthesis components, and method for the production thereof

A method for producing orthosis or prosthesis components for receiving or for fastening to a body part, the method including: applying a base layer to a support corresponding in form to the form of the body part, arranging multiple fastening elements having a base and an interlocking element protruding from the base, on the base layer in defined positions relative to one another, the base of the fastening element resting on the base layer or facing towards the base layer, placing at least one layer of a fiber composite material on the base layer and embedding the base, the interlocking element remaining accessible from the side facing away from the base layer, and curing the at least one fiber composite material layer.

PROSTHETIC INTERFACE

A prosthetic interface includes a body portion having an open proximal end and a closed distal end including a distal cup. The body portion includes a membrane component having a flexible configuration defining an internal flow space extending along a length of the membrane component between an inner side arranged to face a skin surface of a residual limb and an outer side arranged to face away from the skin surface. At least one material coating is selectively applied to the membrane component that interacts with at least one of the membrane component and the distal cup to define at least one breathable region along the inner side that allows fluid flow between the internal flow space and the residual limb, and at least one impermeable region along the outer side that allows for vacuum suspension between the prosthetic interface and a prosthetic socket.
