    摘要： Bone plate and bone screw lock systems are provided for use in surgical implants. In a preferred form, the bone plate or other implantable member defines a bore for receiving a bone screw and a recess in communication with the bore. A screw lock operates in the bore at the recess to engage and lock the bone screw against unintentional movement. The preferred screw lock is shifted about the screw between an unlocked position to allow manipulation of the screw and a locked position in which the screw lock grips the head of the screw to prevent movement of the screw. The screw lock preferably has a c-shaped collar configuration with opposing ends and a camming engagement with the plate or other member in the recess. Upon rotation of the screw lock, the camming engagement causes the ends of the collar to either shift toward one another in which the collar compresses about the screw to lock the screw or away from another to unlock the screw head.

    摘要： A medical instrument apparatus and method is provided to insert and release medical implants. This invention pertains generally to medical instruments and more specifically to spinal implant insertion instruments for spinal fixation systems. The insertion instrument may provide a positive locking and unlocking actuator, preferably in the form of a lever, which ensures that the pedicle screw and yoke assembly is either mechanically locked to the insertion instrument or unlocked to the insertion instrument. The positive locking and unlocking actuator of the insertion instrument eliminates guesswork for the surgeon because the surgeon can readily know if the pedicle screw and yoke assembly is attached to the insertion instrument or not. Superelastic components may also be included to shift components in a first direction and pull components under superelastic tension in a second direction for increased holding force.

    摘要： A spinal fixation system is provided that includes a coupling member and a locking device that is operable to fix an elongate member in the coupling member. There is also provided insertion instruments configured to install and remove various components of the spinal fixation system. In one form, the coupling member includes opposing side wall portions having a resilient portion on at least one of the side wall portions that cooperates with the locking device for being inserted into the coupling member via resilient flexing of the resilient portion. The coupling member and locking device also preferably include cooperating structure therebetween to define a plurality of distinct positions of the locking device in the coupling member.

    摘要： An extrusion puller which comprises an upper jaw, a lower jaw, and means for mounting the upper and lower jaw relative to each other. The upper jaw comprises a plurality of jaw fingers with radially extending gripping teeth circumferentially spaced around the bottom portion of the tooth wherein the attack angle between teeth and the spacing angle between adjacent teeth is selected so that substantially full penetration of at least one of the gripping teeth into the workpiece is achieved without interference from an adjacent tooth. The lower jaw comprises a serrated upper surface comprising a semi-circular scalloped configuration of a plurality of peaks and valleys. The combination of the upper jaw and lower jaw configuration allows for increased gripping strength to be exerted on the workpiece and thereby avoid defects within the extruded workpiece.
