Abstract
Orthotic and prosthetic devices having integrated features such as cushioning features are described, as well as methods for computer aided designing and making of these devices. The orthotic or prosthetic devices comprise a cushioning layer superimposed onto an orthotic or prosthetic shell, the cushioning layer comprising an array (35) of discrete solid and resilient cushioning elements (31). In one preferred embodiment, said cushioning structure is a beam, defined around a centerline of any arbitrary shape. In another preferred embodiment, said cushioning structure has the shape of a spiral.
Claims20
A prosthetic or orthotic device comprising an orthotic or prosthetic shell and a cushioning layer, the cushioning layer being superimposed onto the orthotic or prosthetic shell, the cushioning layer comprising an array of discrete solid and resilient cushioning elements that are formed in an integral manner with the shell.
A method for designing an orthotic or prosthetic device comprising an orthotic or prosthetic shell and a cushioning layer, the cushioning layer being superimposed onto the orthotic or prosthetic shell, the cushioning layer comprising an array of discrete solid and resilient cushioning elements that are formed in an integral manner with the shell, the method comprising:
- providing scan data describing at least part of a patient body;
- converting said scan data into a 3D virtual model on the basis of which a computer based 3D design model of the orthotic or prosthetic device may be constructed;
- and
- adding automatically or interactively at least one of said cushioning elements from an electronic library of cushioning elements to said 3D design model.
A computer program stored in a computer readable memory unit, said computer program comprising instructions that when executed by a processor of a computer system implement a method for designing an orthotic or prosthetic device comprising an orthotic or prosthetic shell and a cushioning layer, the cushioning layer being superimposed onto the orthotic or prosthetic shell, the cushioning layer comprising an array of discrete solid and resilient cushioning elements that are formed in an integral manner with the shell, said method comprising:
- receiving scan data describing at least part of a patient body;
- converting said scan data into a 3D virtual model on the basis of which a computer based 3D design model of the orthotic or prosthetic device may be constructed;
- and
- adding automatically or interactively at least one of said cushioning elements from an electronic library of cushioning elements to said 3D design model.
