  • Publication number: 20070080479
    Abstract: A system and method for manufacturing a custom prosthetic liner. The system may include a shape capture device for capturing the shape of a residual limb. The captured shape may be used to generate a 3-dimensional electronic liner model using a processor and specialized software. A 3-dimensional electronic model of the residual limb may also be produced. Preferably, an interface is provided that allows a user of the system to alter the shape and/or size of the 3-dimensional model(s) to allow the subsequently-produced liner to accommodate particular features of the residual limb. Data associated with at least the resulting 3-dimensional liner model is provided to a manufacturing facility equipped to produce a custom liner therefrom. The data may be remotely transmitted to the manufacturing facility. A positive likeness of the residual limb is created from the data associated with the 3-dimensional model(s), and is subsequently used as a mold core in the liner molding process.

  • Publication number: 20050004472
    Abstract: To scan a body part of a patient, a medical socket contour scanning system including a pattern imposer that imposes a predefined pattern having a plurality of contrast points on the body part to be scanned, and a scanning element including a plurality of image capture devices disposed a pre-defined, spaced apart distance from one another such that adjacent ones have an overlapping field of view. The image capture devices are structured to simultaneously and instantaneously capture an image of the body part with the pattern imposed thereon, a processor, operatively associated with the image capture devices structured to receive the captured images from the image capture devices, compare the captured images from adjacent ones of the image capture devices in order to identify a common element of the pattern, and to utilize the common element so as to define a three-dimensional composite image from all of the captured images which will be utilized to define a socket for a medical appliance.

  • Patent number: 6236743
    Abstract: A three-dimensional digitizing system and method preferably to be useable for the manufacture of a precisely configured clinical support device such as an orthotic brace and/or a prosthetic limb. The digitizing system includes at least one probe which is to be passed over a portion of a three-dimensional body to be digitized, the probe including an exterior housing of known dimensions and being structured to have a position element disposed therein. The position element is structured to provide specific six-degree of freedom position and orientation information relative to a reference element which is also included in the digitizing system.
