The invention discloses a combined titanium plate curvature adjustment device in cervical kyphosis anterior orthopedic surgery, which includes a fixing part and an adjustment device, the adjustment device includes a body and a cover plate, and a seat for placing a titanium plate is installed in the body; There are multiple fixed seat assemblies in the seat, which are clamped with the titanium plate; the top of the placement seat is provided with an adjustment assembly corresponding to the fixed seat assembly; the adjustment assembly includes a pressure plate driven by a power mechanism, and the pressure plate is clamped on the fixed seat assembly. The titanium plate is in contact; a transparent plate perpendicular to the fixing seat assembly is embedded in the top of the cover plate, and multiple arc marking plates are installed on the transparent plate. In the present invention, when the radian of the titanium plate needs to be adjusted, it is only necessary to put the titanium plate into the fixing seat assembly, and the buttons corresponding to each motor are arranged on the cover plate, and the corresponding motor can rotate when the button is pressed. The rotation of the rod drives the threaded sleeve to move in the installation shell, and the two connecting rods are used to push the pressure plate to squeeze the titanium plate, so as to realize the curvature adjustment of the titanium plate.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a combined titanium plate curvature adjustment device in anterior cervical kyphotic orthopedic surgery. Background technique [0002] Anterior cervical surgery can correct the kyphosis of the cervical spine and maintain a good curvature with the help of titanium plates. The curvature of the cervical spine after surgery depends on the good orthopedic function of the titanium plate, so the curvature design of the titanium plate is more important. Generally, the ideal orthopedic curvature keeps the surgical correction rate at about 80%. [0003] At present, the curvature of the titanium plate is estimated by the surgeon himself during the operation, and the correction is performed by himself, so it is difficult to perform accurate correction. Orthotics with precise curvature need to be designed, and patented instruments are designed for orthopedics according to the angle ...
