To quickly and economically manufacture a prosthesis that fits the shape of a stump of a prosthesis user. A prosthesis shape data generation system provided includes: a stump shape data acquisition unit that acquires stump shape data, which is shape data on a stump of a living body; and an estimated prosthesis shape data generation unit that performs an estimation processing by inputting the stump shape data to a machine learning model that has previously learnt a correspondence between a stump shape and a shape of a part or a whole of a prosthesis that fits the stump shape, thereby generating estimated prosthesis shape data that is shape data on a part or a whole of a prosthesis that fits the stump of the living body.

A prosthetic socket for a prosthetic limb is provided. The prosthetic socket comprises a socket body and a first and second structural members. The socket body comprises a distal end and a top edge opposite the distal end. The distal end comprises a prosthetic component attachment mechanism. The top edge comprises a medial fin, a lateral fin, a posterior edge and an anterior edge. The first and second structural members each include a first straight portion, a second straight portion, and a first arch portion. The first structural member is disposed on a medial exterior surface of the socket body and the second structural member is disposed on an lateral exterior surface of the socket body.

The disclosure provides apparatus and methods of use pertaining to a prosthetic finger assembly. In one embodiment, the assembly includes a coupling tip and a distal ring coupled with the coupling tip. The assembly further includes a proximal ring coupled with the distal ring. A rocker formed in an H-shape with a first end forming a first split prong and a second end forming a second split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and H-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. Other embodiments are also disclosed.

A method for manufacturing a customized apparatus with a shape adapted to a specific user's morphology, or a mold for such an apparatus, includes obtaining a description of a generic apparatus, or of the mold for such an apparatus, the generic apparatus being adapted to a generic morphology. A description of the generic morphology and a description of the specific user's morphology is obtained. The descriptions of the generic morphology and of the specific user's morphology are processed to identify a geometric transformation mapping together the generic morphology and the specific user's morphology. The geometric transformation is applied to the description of the generic apparatus, or the description of the mold for such apparatus, in order to define the description of the customized apparatus or the mold therefor. The customized apparatus is then manufactured.

A two-part prosthetic socket which includes an inner socket component having an inner profile substantially complementary to a profile of a residual limb of a patient, and an outer socket component configured to releasably attach about an outer surface of the inner socket component is disclosed. The inner profile of the inner socket component may be determined from digital data output from a medical imaging scan of the residual limb, which provides a three-dimensional digital profile of the residual limb that includes information on the size and location of at least bone and bone spurs, muscle, scar tissue, and neuroma. The digital data may further include a designed operating range for the size and shape of the three-dimensional digital profile of the residual limb based on such information. The two-part prosthetic socket may be manufactured using additive manufacturing, wherein the inner socket may be formed of a flexible material and the outer socket may be formed of a rigid material.

Disclosed herein is a surgical guide tool for use in total hip replacement surgery. The surgical guide tool may include a customized mating region and a resection guide. The customized mating region and the resection guide are referenced to each other such that, when the customized mating region matingly engages a surface area of a proximal femur, the resection guide will be aligned to guide a resectioning of the proximal femur along a preoperatively planned resection plane.

The present invention provides a three-dimensional bioprinter for fabricating cellular constructs such as tissues and organs using electromagnetic radiation (EMR) at or above 405 nm. The bioprinter includes a material deposition device comprising a cartridge for receiving and holding a composition which contains biomaterial that cures after exposure to EMR. The bioprinter also includes an EMR module that emits EMR at a wavelength of about 405 nm or higher. Also provided is a bioprinter cartridge which contains cells and a material curable at a wavelength of about 405 nm or greater. The cells are present in a chamber and are extruded through an orifice to form the cellular construct.

A compliant prosthetic foot is designed and fabricated by combining a compliant mechanism optimization technique with a calculation of low leg trajectory error under a reference loading condition. The compliant mechanism optimization technique includes a set of determinants for the compliant prosthetic foot. An optimized set of determinants of the compliant prosthetic foot is formed that minimizes the lower leg trajectory error relative to a target kinematic data set. The compliant prosthetic foot is then fabricated in conformance with the optimized set of determinants.

The invention relates to a method for creating manufacturing data for manufacturing an orthopedic device, which is producible using the created manufacturing data in an automated manufacturing method, wherein the method comprises the following steps: providing a digital 3D body part model of a body part in a data processing facility, providing at least one digital functional component model of an orthopedic functional component in the data processing facility, which is integratable in an orthopedic device, wherein the digital functional component model contains corresponding component properties of the respective orthopedic functional component, generating at least one digital component interface by means of the data processing facility in dependence on at least one component property of at least one selected digital functional component model of an orthopedic functional component, which is to be integrated into the orthopedic device, wherein the digital component interface includes a receptacle for arranging the at least one selected orthopedic functional component, automatically creating a digital orthopedic model of the orthopedic device to be manufactured based on the 3D body part model and the digital component interface for integration of the orthopedic functional component by means of the data processing facility, and generating the digital manufacturing data from the created digital orthopedic model by means of the data processing facility.
