摘要：
The drilling device for making a bone canal (2) with a curved profile (2b) through a straight cannula (6) anchored beforehand in the body of a vertebra (3) which has a cortical plate (4) of a spinal segment (Sr) of a vertebral column (Cv), comprises a guide pin (8) stemming from a guide pin kit which has, at one end thereof, firstly, a curved profile (8a), the radius of curvature R of which is less than 20 mm, and, secondly, a highly sharpened tip (8b) which is in a direction defined by an angle Y which is less than 90 degrees relative to the longitudinal axis of said pin, the profile of said guide pin (8) making it possible to define, after introduction of the latter into the body of the vertebra (3), two points of contact a and b which guide the free end of an articulated drill (10) in order to position said free end in a direction substantially perpendicular to that of the cortical plate (4) of the vertebra (3) to be pierced.
