The invention relates to a spinal nail -stick connector which is used for fixing CF II rods at both sides of the spine. The spinal screw-rod connector is characterized by comprising a left connecting plate, a right connecting plate, fasteners and a locating element, wherein the left connecting plate and the right connecting plate are both provided with a connecting end and a fixing end, each fixing end is provided with a CF II rod fixing part, a fastener connecting part is arranged close to the CF II rod fixing part, and the CF II rod fixing parts are matched with the fasteners to fix the CF II rods; a locating element connecting part is arranged at the position of the left connecting plate close to the connecting end; a slide connecting part is arranged at the position of the right connecting plate close to the connecting end to the middle part of the right connecting plate; and the connecting end of the right connecting plate overlaps on the connecting end of the left connecting plate, and the locating element is fixedly connected with the locating element connecting part of the left connecting plate by the slide connecting part of the right connecting plate. The spinal screw-rod connector has a short length in the service condition, bolts are less possible to be loosened, and connecting hooks and connecting plates are less possible to produce mutual displacement, thereby ensuring high product safety.
Description
technical field [0001] The invention relates to a medical orthopedic implantation device, in particular to a spinal rod connector (CF connector). Background technique [0002] The spine is the central system of the human body. It not only supports the upper body of the human body, but also undertakes activities such as bending and twisting of the human body. The CF connector is responsible for the connection and fixation of the two sides of the spinal orthopedic fixation system during the operation of spinal curvature deformity correction and spinal trauma correction, and plays a vital role in the success or failure of the operation, durability and patient satisfaction. [0003] see figure 1 , figure 2 As shown, the existing commonly used CF connector is composed of a connecting plate 1 , a connecting hook 2 and a nut 3 . Both ends of the connecting plate 1 are provided with elongated through holes, and the upper end of the connecting hook 2 is provided with threads. In...
