摘要： A connecting apparatus includes a first grasping member adapted to hold a first elongated member and a second grasping member adapted to hold a second elongated member. The second grasping member is operatively connected to the first grasping member so that the first and second grasping members are movable relative to each other. The apparatus further includes a first rotatable rod disposed in mechanical cooperation with the first grasping member, a second rotatable rod disposed in mechanical cooperation with the second grasping member, a first engaging member operatively connected to the first rotatable rod, and a second engaging member operatively connected to the second rotatable rod. The first engaging member is adapted to engage at least a portion of a first pedicle screw. The second engaging member is adapted to engage at least a portion of a second pedicle screw.

摘要： A spinal fixation device includes a coupling, a pedicle screw, and a collet. The coupling has an opening extending therethrough. The pedicle screw has a head mounted to a shank that is positionable within a first vertebral body. The collet is receivable in the opening of the coupling and engagable with the head of the pedicle screw. The collet is selectively positionable between a first position and a second position where the collet engages a spinal rod and prevents one or both of axial and rotational movement of the spinal rod. The collet is adapted to facilitate the connection of the spinal rod to a second vertebral body. The collet defines a saddle having one or more locking features for engaging the spinal rod.
