The system consists of pedicle screws, titanium rods, set screws, and other components. The pedicle screws feature a central cannulated design that supports minimally invasive percutaneous pedicle screw fixation.
This design helps reduce blood loss, muscle and soft tissue disruption, postoperative pain, incision size, and recovery time, while maintaining reliable reduction and fixation. The minimally invasive approach also supports earlier mobilization and rehabilitation.
Spinal minimally invasive surgery is characterized by precise operation, reduced tissue trauma, rapid recovery, and smaller incisions.
The system is designed to help restore vertebral alignment and physiological spinal curvature while providing partial or complete mechanical support for conditions such as vertebral fractures, lumbar disc herniation, spinal stenosis, and spondylolisthesis.
Through a posterior approach, pedicle screws are inserted into the thoracolumbar vertebrae through the pedicles. Distraction, compression, lifting, and reduction maneuvers can then be performed to restore spinal alignment.
The rod is introduced subcutaneously into the U-shaped slots of the pedicle screws using dedicated instruments and secured with set screws. The resulting construct provides stable fixation and a biomechanical environment for thoracolumbar fusion.
All components are made of TC4 titanium alloy.
The pedicle is a strong bony structure connecting the vertebral body and lamina and provides a reliable foundation for pedicle screw fixation. The technology supports three-column stabilization and three-dimensional correction through distraction and compression between the pedicle screws and longitudinal rods.
Pedicle screw fixation is widely used for spinal fracture-dislocations, spinal deformities, lumbar spondylolisthesis, and spinal instability.
The rod connects the pedicle screws and transfers spinal loads within the fixation construct. Titanium alloy rods provide high stiffness, good biocompatibility, and reliable maintenance of sagittal and coronal alignment after contouring.
The system provides standard, break-off, and reduction set screws. Break-off mechanisms are designed to provide consistent locking force and reduce variation caused by manual tightening.
Pedicle screws are available in fixed and multi-axial configurations. Multi-axial screws provide greater flexibility in positioning and angulation, facilitate rod placement, and improve intraoperative adaptability.
The multi-axial structure also helps optimize the fixation configuration and may reduce stress concentration within the construct.
The system provides multiple configuration options, allowing surgeons to select different screw diameters, screw lengths, and pre-contoured rod lengths according to individual patient and surgical requirements.
Suitable for posterior spinal internal fixation procedures for degenerative spinal diseases, spinal trauma, and other conditions requiring thoracolumbar stabilization.
