  • Patent number: 5788697
    Abstract: A cable tensioning device comprises tubular shaft having an outer threaded portion, and a handle member surrounding a portion of the shaft, with the shaft and handle member being connected in screw-threaded relation. The shaft moves longitudinally relative to the handle as the handle rotates, driven by the screw threaded connection. A gripping member is carried on the shaft distal to the handle member for holding a replaceable bit, which, in turn, may carry a cable crimp. A cable lock is positioned typically proximal of the handle member to hold the ends of cables extending through the tubular shaft. Rotation of the handle member can cause the shaft to move longitudinally to lengthen the distance between the cable lock and a crimp held by a bit which, in turn, is held by the gripping member, to impose a tension on the cable. A meter is present for measuring the amount of tension applied to the cable.

  • Patent number: 5741260
    Abstract: Surgical crimping pliers have operating handles and connected, opposed jaws. The jaws define opposed recesses for carrying and crimping a tubular crimp member, which is preferably of oval configuration for carrying a plurality of multistrand cable sections so that, upon crimping, the cable sections are secured together. A capstan is carried on one of the handles for winding a plurality of cable portions so that tension may be placed on both ends of a cable loop array wound about a bone structure, to provide a predetermined, quantitative tension. Then the cable sections within the crimp are secured together by collapse of the crimp. A multistrand cable is preferably used, which exhibits great advantage over single strand wire, and which carries surgical needles of differing type secured to each end thereof.

  • Patent number: 5702399
    Abstract: A surgical connector for cable comprises a body having a pair of opposed ends and a first side extending between the ends. Outwardly extending projections adjacent the first side and ends may be provided to facilitate securance of the connector in a desired position. Cable-receiving bores extend from each of the ends inwardly toward each other, typically at an obtuse angle of less than 180.degree.. The bores have inner ends that communicate with a central aperture which is open to at least the side of the body which is opposed to the first side. Alternatively, the central aperture may extend entirely through the body and be open to both the first side and the opposed side. Also, a novel retention technique for cable is disclosed, for more general use, if desired.

  • Patent number: 5669910
    Abstract: A crosslink member is provided for connecting a pair of surgical support rods in spaced, typically parallel relation. A first connector has a first recess, typically a bore, for receiving and retaining one of the pair of support rods, while a second connector has a second recess that may also be a bore, and which receives and retains the other of the support rods. The first connector is permanently attached to a crosslink rod that extends from the first connector to the second connector. The second connector has a third recess for receiving and retaining a portion of a crosslink rod. Retainers, such as set screws, are used to hold the two connectors of the crosslink member and the support rods together in a desired position. The third recess is closed by a cap with an interengaging sliding rail system.

  • Patent number: 5662653
    Abstract: A link for connecting surgical rods to bone comprises a bone connector such as a bone screw or a bone hook, and a head connected to one end of the bone connector. The head defines an outwardly facing first recess for receiving a portion of a surgical rod which extends transversely of the link and occupies the first recess. A cover is proportioned to fit in a position to cover the surgical rod portion occupying the first recess. A hinge member is carried by the cover and head, to permit vertical pivoting retention between the cover and the head on one side of the recess. A closure on the cover and head is provided at a position opposed to the hinge member. Specifically, the closure may comprise aligned holes, plus a set screw to provide locking closure between the cover and head with a surgical rod extending through the first recess.

  • Patent number: 5649927
    Abstract: A cable winding for retention of bone in surgery having a crimp for retaining the cables together. The crimp has a bore of oval cross section, with its exterior being preferably oval in cross section as well. The cable sections extend through the single bore in side-by-side relation. Outwardly projecting flanges extend from the crimp ends for at least about 120.degree. about the periphery to create a space between the flanges when the flanges rest on bone. This space may be used to receive the crimping jaws during the crimping process so that the crimp does not have to be forced outwardly from the bone during the crimping process. Thus, a more consistent, predetermined tension can be provided to the cable on crimping.

  • Patent number: 5611801
    Abstract: Fixation of a bone fracture may be accomplished by screw driving a threaded pin into the bone, typically in a manner to cause the pin to advance across the fracture area of the bone. It is also common for a pair or more of said pins to be driven into the bone in the manner described above. The threaded pin or pins each may have a cable secured to the pin, extending outwardly from the proximal pin end. One then wraps the cable or cables around the bone to provide external securance for fixation of the bone fracture. A pair of cables used in this process may be secured together under tension by a crimp. Otherwise, a single, free cable end may be secured to a separate pin or other anchor as desired.

  • Patent number: 5116340
    Abstract: A method for surgically securing body parts with a cable, typically making use of crimping pliers which comprises a pair of operating handles and connected, opposed jaws. The jaws define opposed recesses for carrying and crimping a tubular crimp member by manual pressure on the operating handles. A capstan is carried on one of the handles for winding a cable which passes through a tubular crimp member carried in the jaws. By this invention surgical cable may be looped around body parts in surgical operations, and the loop may be permanently secured at a predetermined desired tension.
