Vertebra opposite grooving device

Abstract

The invention relates to a vertebra opposite grooving device, and belongs to the field of medical instruments. An axial assembly comprises two C-shaped rods which are oppositely arranged, the two C-shaped rods are located in the same plane, the two ends of each C-shaped rod are each fixedly provided with a V-shaped plate, the V-shaped plates on the same C-shaped rod are parallel to each other, the folded edges of the V-shaped plates are located on the same straight line, a fixed rod is vertically fixed to the left C-shaped rod, a sliding rod is vertically fixed to the fixed rod, the sliding rod is sleeved with a sliding sleeve, a movable rod is fixed to the sliding sleeve, the movable rod is vertically fixed on the C-shaped rod on the right side, and the sliding rod is vertical to the C-shaped rod. Grooves can be conveniently and efficiently formed in the vertebrae in the opposite directions, the formed grooves are consistent in size and are located in the same plane, positioning is firm and reliable, slipping is completely eradicated, and insertion and fixation of an insertion-connection type intervertebral disc replacement body are facilitated.

Description

technical field [0001] The invention relates to a vertebral facing groover, which belongs to the field of medical instruments. Background technique [0002] Artificial disc replacement is a new method for the treatment of lumbar disc degenerative diseases in recent years, and its clinical application began in the 1980s. It not only removes the diseased intervertebral disc, but also restores the stability and activity function of the segment, theoretically avoiding the degeneration of adjacent segments caused by lumbar fusion. The artificial intervertebral disc is to replace the original intervertebral disc and perform its function by placing a movable artificial prosthesis in the intervertebral space, so as to achieve the purpose of retaining the motion segment and reducing the secondary degeneration of adjacent segments. [0003] This kind of intervertebral disc usually includes two upper and lower fixing plates and an elastic body between the fixing plates. The end faces ...

AI Technical Summary

Problems solved by technology

Manual grooving will result in inconsistent grooving dimensions, and cannot guarantee that the four grooves are in the same plane

There is tissue fluid on the surface of the vertebrae, which is relatively slippery. The cutting tool is easy to slip on the surface of the vertebrae, resulting in inaccurate cutting and easy damage to the surrounding tissues.
