TiLock® Modular System Spinal Fixation

TiLock® Modular System Spinal Fixation

TiLock® Modular System Spinal Fixation is an advanced medical device designed for posterior spinal fixation, representing a significant innovation in orthopedic surgical technology. This sophisticated system uniquely addresses the challenges of spinal stabilization through its modular design, featuring a revolutionary one-way attachment mechanism that combines a ball and socket with a spherical snap ring in a conical pocket. The system's distinctive architecture allows surgeons to first place a low-profile screw and subsequently attach the tulip component, providing enhanced operative visibility and superior access for decortication procedures. The design incorporates polyaxial capability with 60 degrees of motion, while maintaining exceptional structural integrity capable of supporting up to 1000 pounds of separation force. The system's components include precisely engineered tulips available in low top, reduction top, or extended top variants, with dimensions of 12.2mm diameter and 16.5mm height, complemented by screws ranging from 25-60mm in length and 4.5-8.5mm in thread diameter. Notable features include opposing angle interface set screws, break-away towers on extended tulips, and reverse angle buttress threads that minimize tulip splay during final tightening. This innovative medical device, which received recognition with an Iron A' Design Award in the Medical Devices and Medical Equipment Design category, can be implemented through conventional open approach, midline, or minimally invasive surgical techniques, demonstrating its versatility in clinical applications. The system's development involved sophisticated engineering processes, including Solidworks conceptualization, ANSYS mechanical evaluation, and rigorous testing according to ASTM standards 1717 and 1798.
