Pre-drilling of the pedicle bone path: According to the positioning requirements of the pedicle screw, a hole drill is used to drill a hole 10mm deep at the nail entry point, and then a flat-head Kirschner wire with a diameter of 1~1.5mm is used to pre-drill and advance by hand. Always keep the probe parallel to the intervertebral space and not pass through the bone canal. If the probe is inside a normal pedicle, there should be a substantial noise. Moving the Kirschner wires up and down at this time can feel the surrounding bony structures. Take out the Kirschner wire, and select the corresponding pedicle screw according to the length of its entry into the bone canal. Top groove design, convenient for tool connection.Single inner locking device, one step locking. Negative angle thread design prevent the arm from bursting and reduce slippage. Strengthen the four-thread thread screw to further increase the holding force of the pedicle. Double thread design, faster nailing speed. 10mm tapered head, automatical guidance to avoid breaking the pedicle, no selftapping groove design, safer nailing.
