Abstract: A universal device for supporting bones and surgery tools in orthopaedic surgery consists of two rods supporting two spaced bone/tool holders installed in alignment to each other on opposite ends of the rods. The holders have V-shaped prisms with adjustable yokes for securing the broken bone part or a drilling tool in the respective prisms with a drill arranged coaxially to the facing bone part. One bone/tool holder is rigidly fixed to the rods, while the second holder slides relative to the fixed holder. The moveable holder is fixed between the nuts, e.g., for holding the parts of the broken bone in butt connection for growing together naturally. As compared to the known device of the same type, the device of the invention is light in weight, more universal in use, and is more simple in construction.

Abstract: A supporting device consists of two rods supporting two spaced bone/tool holders installed in alignment to each other on opposite ends of the rods. The holders have aligned V-shaped prisms and are provided with adjustable yokes for securing the broken bone part or a drilling tool in the respective prisms with a drill arranged coaxially to the facing bone part. One bone/tool holder is rigidly fixed to adjacent ends of the rods, while the second holder has a sliding fit over the threads on the opposite ends of the rods. The freedom of movement or fixation of the position of the second holder are determined by positions of two nuts screwed onto the threaded ends of the rods. The moveable holder is fixed between the nuts, e.g., for holding the parts of the broken bone in butt connection for growing together naturally.

Abstract: A device for coaxially drilling holes in fractured bones for intramedullary fixation includes of a frame (20) supporting a first V-shaped support (34) for a first part of a fractured bone and a second V-shaped support (56) for a second part of the fractured bone. The V-shaped supports are spaced from each other. The apparatus has a drilling head (28) with a calibrated pin (82) at the rear side of the drilling head (28). The drilling head is alternatingly installed in the aforementioned V-shaped supports (34 and 56) for drilling coaxial and strictly aligned holes in both parts of the fractured bone. The calibrated pin (82) has the same diameter as the drill bit (78) of the drilling head and is intended for insertion into the bone hole which is drilled first in order to support and align the drilling head (28) with the second part of the bone during drilling of the second hole.

Abstract: A two-part prosthesis, including a stem and head portion, for a hip or other joint is provided. Briefly stated, a intramedullary stem is provided having flexibility that is comparable to that of the surrounding bone. The intramedullary stem comprises a strong and resilient core that is coated with a biocompatible material. The flexibility of the stem distributes the loading forces from the joint more uniformly over the supporting bone with the result that bone degeneration from stress shielding is minimized or eliminated. Additionally, the prosthesis head is made of entirely biocompatible materials and is shaped so as to fit conventional joint sockets. The modular, two-part structure of the prosthesis allows the stem and head portions to be selected to provide the best fit for the patient.

Abstract: An apparatus comprising an internal bone fixation apparatus for supporting and securing together two sections of a fractured elongated bone within a patient's body. Generally, the apparatus includes first and second fixation portions which are disposed in holes formed in the internal cavity of the fractured bone on respective sides of the fracture, and a means for connecting these fixation portions together. In the preferred version of the present invention, the connecting means is adjustable such that the first and second fixations portions can be drawn together or spread apart in the longitudinal direction, thereby similarly moving the first and second sections of the fractured bone. In addition, the structural and securing portions of the invention are made from strong resilient metals, that are not necessarily compatible for long term contact with the body of the patient. However, the metals are completely isolated from any contact with the body of the patient by insulating materials which are compatible.

Abstract: This apparatus is for cooking various food items under pressure, and is particularly well adapted for cooking chicken and steaks rapidly at home. A toggle link clamp mechanism is adapted to press food against the bottom of any pan, and for applying a desired variable pressure to all portions of the food, whereby rapid and high-grade cooking is accomplished. The clamp is adjustable for various pans and/or other vessles.
