System for replacing a disc between two vertebrae

摘要

The system has an introduction guide (30) introducing intervertebral cages (10) between two consecutive vertebrates. The guide has a tube (31) with rectilinear and curved shaped parts (34-1, 34-2) that are provided with proximal and distal openings (32, 33-1) of the tube, respectively. Introduction units (21) introduce the cages in the part (34-1) of the tube in a manner to arrange its longitudinal plane that is conformed with an axis (40) of the part (34-1). A push rod (43) is penetrated in the tube through its opening (32). Control units (45) control displacements of the rod in the tube.
