The invention discloses a combined type titanium plate curvature adjusting device used in a cervical vertebra kyphosis anterior orthopedic surgery. The combined type titanium plate curvature adjusting device comprises a fixing part and an adjusting device, wherein the adjusting device comprises a machine body and a cover plate; a containing seat for containing a titanium plate is mounted in the machine body; a plurality of fixing seat assemblies are arranged in the containing seat and clamped with the titanium plate; adjusting assemblies in one-to-one correspondence with the fixing seat assemblies are arranged at the top of the containing seat; the adjusting assemblies comprise pressing plates driven by power mechanisms; the pressing plates make contact with the titanium plate clamped on the fixing seat assemblies; a transparent plate perpendicular to the fixing seat assemblies is embedded in the top of the cover plate; and a plurality of radian marking discs are mounted on the transparent plate. According to the combined type titanium plate curvature adjusting device, when the radian of the titanium plate needs to be adjusted, the titanium plate only needs to be placed in the fixing seat assemblies, buttons corresponding to motors are arranged on the cover plate, the corresponding motors can rotate by pressing the buttons, a screw rod rotates to drive a threaded sleeve to move in a mounting shell, and two connecting rods are used for pushing the pressing plates to extrude the titanium plate, so that the curvature adjustment of the titanium plate is realized.
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 ...
