摘要：
The utility model relates to medicine and can be used in neurosurgery, orthopedics, traumatology, Spine, in particular in the field of spinal correction and fixation systems. Apparatus monoaxial pedicle screw comprises a screw (1) and the blocking screw (2). The propeller 1 is formed with a thread (3) on the working part and with a head (4) having a blind hole (5) with an internal buttress thread (6) and the groove (7) with the possibility of inserting a longitudinal pin (8). The thread profile (3) of the working part of the screw (1) and AC represents a scalene trapezium (9), the base of the trapezoid (9) decreasing from the head (4) of the screw (1) to its tip (10). The outer diameter of the working part of the screw (1) is constant, and the inner diameter - decreases from the head (4) to the tip (10), forming a cone-shaped rod (12) of the screw (1). The cone-shaped rod (12) of the screw (1) is arranged to form two parts (13) and (14) of different taper with smooth transition from one part to another and with decreasing angle forming a conical end portion (14) of the rod (12). At least the first from the tip (10) of the screw thread winding (3) is formed with a recess (15) forming flute with cutting edges. At the base of the groove (7) of the head (4) is a notch (16). Angles (11.1) and (11.2) scalene trapezium (9), the thread (3) of the working part of the screw (1), in particular, are 5 ° and 40 °. On the upper plane of the locking screw (2) is an alignment notch (19) blocking screw (2) is configured as an element (20), in particular in the form of an internal hexagon, enabling to apply torque for screwing the locking screw (2) in the head (4 ) of the screw (1). The technical result of the utility model is to provide stable fixation of damaged spinal segment with simplification of manipulation during surgery. 1 NRM f ly-5-yl.Полезная модель относится к медицине и может быть использована в нейрохирургии, ортопедии, травматологии, вертебрологии, в частности, в обла
