Instructions
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. Pedicle screw placement: For spinal fractures, two pairs of screws are usually implanted in the adjacent vertebrae above and below the diseased vertebra, while for spondylolisthesis, a pair of lifting screws are added to the diseased vertebrae. After the pedicle bone is protruded, the pedicle screw is screwed into the pedicle screw to correct the deformity. In addition, it should be noted that the screwed-in lifting screw must be on the same plane with the two vertebral bodies after the correction of the diseased vertebra, so that the connecting rod can be installed smoothly. Correction of spondylolisthesis: Correction of spondylolisthesis by lifting screws, and the three pins on the same side are placed on a flat surface so that the connecting rod can be inserted. Device connecting rod: Connect the connecting rod with the vertebral screw or pedicle screw with locking screw according to the product characteristics, and adjust it according to the type of spinal injury and the need for reduction. After the spinal correction or spondylolisthesis reduction, the screw is locked. If necessary, install a horizontal connection device.
Features
1.Single inner locking device one step locking
2.Top groove design convenient for tool connection
3.Negative angle thread design prevent the arm from bursting and reduce slippage
4.Double screw thread design faster nailing speed
5.Strengthen the four-thread screw to further increase the holding force of the pedicle
6.10mm tapered head,automatical guidance to avoid breaking the pedicle, no self-tapping groove design, safer nailing
