The invention provides an adjustable interbody fixation and fusion device and relates to a spinal interbody
fusion surgery instrument. The adjustable interbody fixation and fusion device is provided with an upper support platform, a lower support platform, a left sliding support block, a right sliding support block, a rotating shaft, a main rotating gear, an auxiliary rotating gear and a
handle, wherein the left sliding support block and the right sliding support block are arranged on the left side and the right side of the upper support platform and the lower support platform respectively; the rotating shaft is arranged between the upper support platform and the lower support platform; the left end and the right end of the rotating shaft are connected with the left sliding support block and the right sliding support block respectively; the main rotating gear is connected with the right end of the rotating shaft; the auxiliary rotating gear is meshed with the main rotating gear; the
handle is connected with the main rotating gear. With the adoption of the adjustable interbody fixation and fusion device,
surgical operation can be simplified, surgical time can be shortened, the
surgical treatment effect can be improved, and the
medical expenses of a patient can be reduced; the height of the device can be adjusted according to the interbody space height, the fusion range of a
kidney-shaped fusion surface is wider, the fusion effect of a bone trabecula structure is better, the
surgical operation is more simplified, and the long-
term effect of fixation and fusion is better.
