SURGICAL CONNECTORS AND INSTRUMENTATION

摘要

Embodiments of the present invention are directed toward a system of apparatuses to correct spinal deformities along with associated surgical techniques. The apparatuses comprise passages or channels in which spinal rods of differing diameters may be secured to allow a surgeon to vary the diameter of rods used along the length of the spine. Additionally, embodiments of the present invention are directed toward instrumentation for reduction of spinal rods into spinal pedicle screws.

主权项

1. A medical device, the medical device comprising a spinal rod receiving channel and a rod retaining set screw; wherein,
the spinal rod receiving channel comprises at least a first circular hole, a second circular hole, and a third circular hole; the first circular hole, the second circular hole, and the third circular hole are parallel; the first circular hole, the second circular hole, and the third circular hole have offset centers disposed along a single line; the first circular hole forms an upper arc of the rod receiving channel; the second circular hole forms a middle arc of the rod receiving channel; the third circular hole forms a lower arc of the rod receiving channel; the middle arc and the lower arc are connected by a connecting slant; and the rod retaining set screw secures a spinal rod disposed in the spinal rod receiving channel into the medical device.
