  • Patent number: 8852192
    Abstract: A surgical procedure for preparing a graft for insertion in an opening in a human body, according to which a mold is formed in the opening and transferred from the opening to a position adjacent a stylus. A contour of the mold is traced with the stylus; and the tracing movement of the stylus is transferred to corresponding movement of a cutting member so that the cutting member cuts the same contour in the graft.

  • Patent number: 7373727
    Abstract: An apparatus for determining the angle between two adjacent objects such as the corner of a wall or the pitch of a roof, and the appropriate angle of a corresponding miter cut. The apparatus includes a base member that is configured in a substantially planar manner. The base member includes a channel for slidably receiving the ends of two support members. The support members are pivotally mounted to opposing angle arms that extend laterally in opposing directions from the base member and function to movably connect the angle arms to the base member and form a pointer thereon. The base member further includes numeric indicia that indicate the angle of the angle arms and the corresponding miter angle cut adjacent to the channel on the base member.

  • Patent number: 7131470
    Abstract: A table with a working surface has a parallel rail on each side of the working surface. A slide assembly includes a shaft with ends and a pair of brackets. Each bracket has a hole. The holes receive the ends of the shaft. The slide assembly includes cylindrical tunnels. The tunnels slidably receive the rails. An operating assembly has primary and secondary arms. Each arm has a free exterior end and an interior portion. The interior portion is coupled to the shaft. A router is secured to, and depends from, the free end of the secondary arm. Control mechanisms include a scribe. The scribe is secured to, and depends from, the free end of the primary arm. Movement of the primary arm and scribe with respect to a template will cause corresponding movement of the secondary arm and router with respect to work pieces to be routed.

  • Patent number: 6223444
    Abstract: The present invention comprises an arrangement for the remote sensing and recordation of information about a body component. The arrangement includes a stylus held within a support head. The support head has an electrode therein for the detection and recordation of stylus contact with a body component. A plurality of parallelogram linkages articulably support the stylus. The linkages have a first or input end and a second or output end. A motion tracking generator is attached to the output end of linkages. A sensor is arranged to receive and record signals from the tracking generator in a plurality of orthogonal planes, so as to permit the generation and recordation of contours, location and domain of the body component being sensed by the stylus.
