<p>A toolkit for easily implanting a vertebral support device, in particular an interlaminar prosthesis, through a minimally invasive surgical access. In an exemplary embodiment, the toolkit comprises a vertebral distractor (10) that has a means for creating and maintaining a predetermined distraction between two adjacent vertebrae (21a/b), and a means for maintaining the edges 29' and 29" of a minimally invasive approach tissue cut (29) at an open position, thus stabilizing it against elastic return of the tissues (20). In a preferred exemplary embodiment, a distractor is used which comprises a couple (30) of levers (31a/b), that are movable about a hinge (15) and that can be locked at a predetermined position, and whose end have a couple of distraction portions (33a/b) adapted to be inserted between spinous processes (23a/b), such that by spreading apart levers (31a/b) the distraction of the two vertebrae (21a/b) can be obtained.</p> |
