Abstract: A robotic system for performing minimally invasive spinal stabilization, using two screws inserted in oblique trajectories from an inferior vertebra pedicle into the adjacent superior vertebra body. The procedure is less traumatic than such procedures performed using open back surgery, by virtue of the robot used to guide the surgeon along a safe trajectory, avoiding damage to nerves surrounding the vertebrae. The robot arm is advantageous since no access is provided in a minimally invasive procedure for direct viewing of the operation site, and the accuracy required for oblique entry can readily be achieved only using robotic control. This robotic system also obviates the need for a large number of fluoroscope images to check drill insertion position relative to the surrounding nerves. Disc cleaning tools with flexible wire heads are also described. The drilling trajectory is determined by comparing fluoroscope images to preoperative images showing the planned path.

Abstract: A spinal intervertebral support implant, for fusion or for dynamic stabilization purposes. A rod, preferably in the form of a screw, is inserted obliquely from the pedicle of an inferior vertebra into the body of a neighboring superior vertebra, through the disc space. The rod can be anchored into the body of the superior vertebra by means of a force fit or a screw thread. A pile of elements is disposed on the rod in the disc space like a pile of washers, so that the compression load between vertebrae is carried partly by these elements. These elements can be inserted through the bore through which the rod was inserted in a tightly folded configuration, and deployed into their washer-like form only when in position in the intervertebral space, such that there is no need for any additional incisions.
