  • Patent number: 4409974
    Abstract: A surgical implant for the fixation of bone portions and methods for using the same to reduce bone fractures with or without the use of bone fixating plates and in a variety of surgical procedures where rigid fixation of bones or bone portions even under great stress is required. The implant has a generally frusto-conical head with a plurality of arms hingeably connected thereto, the arms capable of moving from a retracted position to and extended position. A rectilinear bore having a diameter slightly greater than the greatest effective transverse dimension of the implant device with the arms in the retracted position is drilled through the bone portions to be fixated. A guiding tube or shaft is provided to guide the head of the implant device with the connected arms in retracted position into the bore.

  • Patent number: 4409973
    Abstract: In high tibial osteotomy a cross-shaped gauge having downwardly-depending side arms is positioned toward the end of the tibia, with the depending arms adjacent the arcuate path of the proposed saw cut. The cross-shaped gauge establishes a first indicia between said depending arms for positioning the arcuate axis of a semi-cylindrical saw, and a second indicia proximate the upper end of the longitudinal arm of the gauge for locating the saw arc. A saw blade of correct radius is then selected. The first indicia established by the gauge positions a first hole drilled through the bone for receiving a guide pin or rod, and the second indicia locates a second hole on the saw line for receiving a depth gauge. An arm on the depth gauge is aligned with a plurality of spacers placed on the aforementioned pin or rod, and the pin or rod is received along a cylindrical bore in the saw. When the saw is operated, the spacers arrest movement of the saw blade when it has passed through the bone.

  • Patent number: 4408601
    Abstract: A bone compression plate is provided with several sliding slits for countersunk bone screws having ball heads in the longitudinal dimension of the plate. Each sliding slit is countersunk in its end area opposite the fracture, the depth of which countersinking in the plate determines the final axial position of the screwhead. That depth is greater than that of the rest of the sliding slit. The bearing surface of the countersinking for the screwhead extends over an area which is included within an angle of more than 180.degree.. It is thus possible, on the one hand, to move the plate with respect to the pieces of fractured bone to obtain a pressing together of the two pieces of bone when the bone screw has not been screwed tight. On the other hand, it is possible to fasten the plate immovably to one piece of the fractured bone by inserting a bone screw into the countersink slit.

  • Patent number: 4407276
    Abstract: A light-weight brace adapted to be affixed externally of a patient's leg so that it lies partly above and partly below the person's knee. The apparatus includes first and second flexible sheets of cushioned material which are adapted to be snugly wrapped around the thigh and calf. The width of each of the flexible sheets is sufficient to circumferentially envelope at least most, and preferably all, of its associated leg member; and the length of each sheet is sufficient to encompass at least half of the length of the respective leg member. A preferred cushioning material is a sheet of polyurethane foam (about 9 mm thick) bonded to a sheet of pile-type material having sufficient "nap" to serve as an anchor for resilient hooks of the Velcro type. Also provided are first and second pairs of elongated braces, which braces are relatively stiff so as to resist both torsion and bending loads. The pairs of elongated braces are adapted to lie on opposite sides of the wearer's thigh and calf.

  • Patent number: 4403613
    Abstract: A one-piece pacifier for an infant comprising a shield having a nipple extending from one side and a handle extending from the other, the lower portion and sides of the shield being curved away from the nipple to present a larger area where the shield might rest against an infant's chin and face thereby reducing irritation, and the handle being angled downwardly towards the curved portion of the shield so as to deflect toward the shield rather than push the nipple towards the infant's throat when force, such as when the infant presses its face against a mattress, is applied to the handle side of the pacifier.

  • Patent number: 4392488
    Abstract: Device for the support of joints for orthopedic and surgical purposes, which permits use on the periphery or surface of the joint, in the principal plane of movement. The adaptation of the splint to, and its accompaniment of, the change in the configuration of the joint surface upon movements is assured by concatenation linkage of the joint splint, wherein the links, which are constructed as obtuse-angled bell cranks, are united to one another by articulations to form a chain such that, in the case of a radial movement of the splint links, they simultaneously produce a lengthening of the splint according to the principle of the Nuremberg scissors.

  • Patent number: 4384574
    Abstract: An apparatus used to control human beings through the application of localized pressure to their body and appendages. The claimed apparatus has a substantially straight, elongated first arm, and spaced therefrom and generally parallel thereto, a curved, elongated second arm. A member connects together one end of the first arm to the adjacent end of the second arm. The first arm extends beyond the second arm and a blunting element is fixedly secured to the free-end. The second arm has a curved midportion which curves downward and extends toward the first arm to a distance from the first arm sufficient to receive an appendage. An upwardly curved end portion of the second arm connects the curved midportion to the connecting member, and attached to the end of the curved midportion remote from the connecting member is an upwardly curved free-end portion.

  • Patent number: 4379452
    Abstract: A prepackaged, self-contained fluid circuit module is selectively movable by an operator into and out of operative association with one or more pump rotors. The module includes a housing which supports two or more flexible conduits, which together define a prearranged fluid circuit. Portions of the flexible fluid conduits are outwardly disposed from the housing in upright, freestanding positions, even when the module is out of operative association with the pump rotors. The upright portions are purposely arranged relative to each other to facilitate only a particular operative relationship between the fluid circuit and the pump rotors when the module is subsequently moved into operative association therewith.

  • Patent number: 4379451
    Abstract: To receive the weight of the body from the pelvis and distribute it evenly to the shaft of a fractured femur while bracing the fractured femur, an intramedullary hip pin engages a plate secured to the lateral cortex of the shaft. The hip pin has an enlarged end portion positionable within the head and neck of the femur to receive and distribute forces from the pelvis and to impede protrusion of the pin through the head of the femur. The hip pin also includes an expansible member in the form of a cage for tightly securing the hip pin within the head and neck of the femur. The plate is adapted to be secured to the outer surface of the femur and includes an inclined, tubular, pin-receiving portion extending partially into an opening formed through the surface of the femur and into the neck of the femur.
