Transconnector

摘要

A transconnector for use in interconnecting a pair of longitudinal spinal rods in a spinal fixation procedure. The transconnector includes a bridge member and first and second spinal rod engaging members. The bridge member may include first and second members, wherein the first and second members are moveably associated with one another so that the distance between the first and second spinal rod engaging members can be adjusted. The first and second spinal rod engaging members include a rod receiving channel for receiving one of the spinal rods therein. The spinal rod engaging members may be articulating in, for example, the yaw and roll positions or non-articulating with respect to the bridge members. The spinal rod engaging members preferably include a spring, for example, a spring washer, to provide an opposing force so that the spinal rod engaging members can provisionally snap onto the spinal rods.

主权项

1. A transconnector configured to capture a spinal rod, the transconnector comprising:
a bridge member having a first end, a second end, and a bore that extends along a first bore axis through the first end; and a rod engaging member that is configured to be supported by the first end of the bridge member in a plurality of positions relative to the bridge member, the rod engaging member including an upper clamp body, a lower clamp body, and a rod receiving channel defined by the upper and lower clamp bodies, the rod engaging member further including an actuation screw and a bore that both extends along a second bore axis and is configured to receive the actuation screw; wherein when the rod engaging member is supported by the bridge member, the first central axis is aligned with the second central axis such that the actuation screw is configured to be received within the bore of the bridge member and the bore of the rod engaging member, such that actuation of the actuation screw: 1) changes a distance between the upper and lower clamp bodies, and 2) fixes the rod engaging member in one of the plurality of positions with respect to the bridge member.
