Description of the Invention: [Technical Field] The present invention relates to a spinal nail fixation device, and more particularly to a rough surface of a ball-end end of a ball-end screw, which can perforate the periphery of a fixed seat bottom surface The surrounding wall strengthens the fixed screw fixation device of the card top. [Prior Art] Conventional scoliosis correction, when a large number of spinal nails are used as a correction, nailed into each vertebra joint, and one or more connecting rods are connected, and the bone nails are connected, and then the force is rotated. The connecting rod adjusts the position, height and angle of each nail, and corrects the spine which is originally in a curved state, so as to restore the state of the normal normal spine and the approaching straight line. In this way, in addition to the generally fixed uniaxial spinal nail, the above-mentioned operation is a multi-axial vertebra nail with a rotatable angle, and when the bending angle of the spinal joint is too large, the torsion joint point and the force point are implanted. Therefore, the fixation stability, coupling force and tolerance of these multi-extracted spinal nails are very important. "There are relatively common multi-axial vertebrae nails during surgery, screw people - after the spine joints, the other bone nails or the points of the force points, # is to fix the seat, even the social pole: 2, and the seat Lock the material assembly _ fixed parts, press each group of materials, press the heart 1 dry, so that the fixed side multi-axial spine nails, the use of θ 』, the friction between the components There is no one to strengthen the pressing components, such as the elastic ring paper θ| ping ^ week size to fit the gap of the % circle pad, can increase the fixation of each component. With the fixed and the multi-axial vertebra The ball joint of the 200847990 seat used in the nail, using the M & .sp spoon also ^ 疋 the ball head screw ball end end top face 盥 _ $ & the seat is tightly fixed, 苴 by + two /, 镔Fixed 疋 or it can also add a ring set to $ forming - fit flat, " $ and in the money master end to accept the connecting rod and set by the fixing member #.
