摘要:
Embodiments of a modular prosthetic socket for a residual limb of a lower extremity of a patient are provided. Modular components include a base, multiple strut connectors, and multiple longitudinal struts. The base is selected from a collection of bases. The multiple strut connectors are selected from a collection of strut connectors, each strut connector being adjustably connectable to the base along the periphery of the base. The multiple longitudinal struts are selected from a collection of struts, each strut including a thermoplastic-fiber composite material, each strut being connectable to the base along the base periphery via one of the strut connectors. At least one of the component collections includes at least one of multiple sizes or multiple shapes of bases, struts or strut connectors, respectively. The prosthetic socket circumscribes a proximally-open internal space configured to conform to the residual limb of the patient.

The invention relates to a prosthetic socket for a residual limb of the lower extremity or upper extremity of an individual person. The residual limb has particular dimensions and anatomical contours; the prosthetic socket has dimensions and contours that fit the dimensions and contours of the residual limb. The prosthetic socket may also fit in a manner that is biomechanically particularly appropriate for the individual. The prosthetic socket is an assembly of components from groups of components that include (a) struts arranged longitudinally with respect to the residual limb, (b) proximal brim members arranged proximally to the struts and connected thereto; and (c) distal socket members disposed at the distal base of the prosthetic socket. The socket components within these groups may be modular in that they can vary with respect to dimensions and/or contours, and yet have common connecting features that permit assembly of the components together to form the prosthetic socket.

An alignable coupling assembly embodiment for coupling distal and proximal prosthetic components includes a pair of parallel circular plates rotatably disposed in the circular receptacle of a support plate. The circular plates are configured such that they can be unpressed or a pressed. The unpressed condition allows rotation of the paired plates and the pressed condition prevents such rotation by way of a first friction lock. The paired circular plates further have a rectangular slot into which a longitudinal connector is slidably disposed, and which is subject to a second friction lock that prevents sliding when the connector is pulled distally. Rotational movement of the plates and sliding movement of the connector in the slot cooperate to allow its positioning at any point within an anterior-posterior/lateral medial grid centered on the longitudinal axis of the proximal prosthetic component. A distal pull on the longitudinal connector engages both first and second friction locks.

Embodiments of the technology include a prosthetic socket suspension device having a distal cup portion and a liner garment portion, these two portions being bonded together. In various embodiments, a distal cup may be disposed within a liner, a liner may be disposed within a distal cup, and a distal cup may be disposed between distally bifurcated internal and an external layers of a liner. Distal cup are sized and shaped to accommodate a distal portion of a residual limb of a patient. Distal cup embodiments may be formed from either a thermoplastic or thermoset plastic composition. Thermoplastic cup embodiments may be thermally reformed around the distal portion of the limb so as to create a highly conformal fit. Embodiments of the technology further include methods fabricating the prosthetic suspension device, and methods of thermally reforming the suspension device so as to fit a distal aspect of the residual limb of a patient.

A method is described for fabricating a sequential series of orthopedic devices custom designed to change a configuration of a body part of a patient from a pretreatment configuration to a treated configuration. The method involves receiving digital data representing the body part of the patient in the pretreatment configuration. The method continues by generating, using the digital data, a sequential series of digital 3D body part models, including at least an initial body part model representing the pretreatment configuration of the body part, a final body part model representing the treated configuration of the body part, and at least one intermediate body part model representing the body part in an intermediate configuration between the pretreatment and treated configurations. The method further involves fabricating the sequential series of orthopedic devices from the sequential series of digital 3D body part models.

A flexible distal cup for use as part of a modular prosthetic socket for a residual limb may have a substantially closed distal end, an open proximal end, an inner surface and an outer surface. The flexible distal cup is configured to reside within an outer support structure of the prosthetic socket and to receive a distal portion of the residual limb. In some embodiments, the flexible distal cup may be made of a composite polymer composition, including an ethylene-vinyl acetate (EVA) copolymer and polycaprolactone (PCL). The EVA copolymer may be between about 45% and about 55% of the composite polymer composition by weight, the vinyl acetate of the EVA copolymer may be less than about 25% of the EVA copolymer by weight, and the PCL may be between about 45% and about 55% of the composite polymer composition by weight.

A system and method are described for profiling a distribution of forces transferred from the body weight and the residual limb of a wearer of a prosthetic socket through the socket. The system may include a prosthetic socket, a sensor network comprising multiple sensors coupled with the prosthetic socket in a pattern defining multiple internal regions within the prosthetic socket, and a processor coupled with the sensor network and configured to receive sensed data from the sensor network, divide the sensed data into groups corresponding to the multiple internal regions within the prosthetic socket, and process the sensed data to provide force distribution profile data corresponding to the force distribution profile.
