DEVICE FOR JOINING A LONGITUDINAL SUPPORT WITH A BONE FIXATION MEANS

摘要

The invention relates to a device for joining a longitudinal support (11) with a bone fixation means (1), in particular a pedicle screw. Said device comprises: A) a joining piece (5) having a coaxial hollow area (8), which passes through said joining piece (5) from the upper end (6) to the lower end (7) and tapers to the lower end (12) by means of at least one shoulder (9) as well as a channel (10), which passes through said joining piece (5) perpendicularly to the longitudinal axis (2) for receiving a longitudinal support (11); B) a cap (12) and C) clamping means (13), which can be joined to the rear end (19) of said cap (12) and by means of which a longitudinal support (11) can be fixed within said channel (10), whereby D) complementary locking means (21), engaging into each other for attaching the cap (12) to the joining piece (5), are externally arranged on said joining piece (5) and in the second hollow area (18) in said cap (12).
