Spinal screw assembly with constrained angulation features
The granted patent US12042186B1 describes a spinal screw apparatus designed to enhance the functionality and adaptability of spinal fixation systems. The apparatus consists of a screw with a shaft and a screw head, along with a movable head that features a U-trough for engaging a spinal rod. The movable head is characterized by its unique design, which includes a through-passageway with both cylindrical and planar surfaces, allowing for precise alignment and movement relative to the screw head. The design ensures that the first and second bottom surfaces of the movable head are positioned in different planes, facilitating a range of angular positions for the screw. This configuration is intended to improve the stability and adjustability of spinal implants during surgical procedures.
Additionally, the patent outlines a kit that includes multiple screws and movable heads, emphasizing the versatility of the system. The movable heads are designed to accommodate the screw heads while providing a bottom opening with a contact perimeter shape that combines curved and straight portions, enhancing the engagement with the spinal rod. The method described in the patent details the steps for limiting the angular positions of the screw in relation to the movable head, including the loading of screws and the engagement of tools. This innovative approach aims to streamline spinal surgeries by allowing for better control and positioning of screws, ultimately contributing to improved patient outcomes in spinal stabilization procedures.
