Abstract

The instrument is used in the surgical intervention of the vertebral column. The shortcomings of the known means is the impossibility of stageless positioning of the height screw. The unreliable mechanical connection, the large sizes and their increased stiffness result in delayed knitting together of the bones and breaking the individual elements. According to the invention screw (1) has a hexagonal head (2) which continues with a conical journal (3) ending by normal threading on which a nut (4) is mounted. Between the head (2) and nut (4) a bracket (5) is fitted which engages a rod (6). On the bracket (5) a conical hole is machined which ensures, between it and journal (3), a specified angular clearance. Bracket (5) is in contact with the hexagonal head (2) and nut (4) by means of respective spherical surfaces having a common centre and this centre appears as a peak of the conical surfaces of journal (3) and the conical hole of bracket (5). 1 claim, 1 figure
