Field of the Invention The present invention relates to a multi-axial spinal fixation rod, and more particularly to a multi-axis dynamic spinal fixation rod. Prior Art In the spinal fixation, the fixed rod is often used as an auxiliary fixation device, but since the spine is not a straight line, the vertebrae are usually not parallel, for example, the lumbar vertebrae are lordosis. Therefore, if the fixed rod that is originally in line is directly integrated with the multiple bone nails implanted in the vertebral joint to be fixed, it will force the spinal joints to be fixed not in the straight line to become in a straight line, and the original should not be parallel. The individual vertebrae to be fixed become parallel. In order to avoid the above-mentioned deficiency, the medical community has proposed various improved structures, such as: 1 • Solve problems with angled screws, such as. §_❹ 5'176,679, US-5,196,014, US-5,257,994, US-5,466,238, etc.; for example, US 5,176,679 utilizes locking pins designed t0 have specific angies, see the case to 扑And its description) 'to solve the above-mentioned spine joints are usually not parallel problems. However, these methods are only suitable for the fixation of the vertebrae between a fixed rod and two bone nails (because the two points are in line), but not for a fixed rod and three (inclusive) bone joints above the bone nail. Fixed, because the three points are usually not in a straight line, and the '4th method does not have the function of bending (7) printing) or twisting (four) sting/stretching after the operation. 200936097 2. Solve problems with angled connectors such as US-5,257,994, US-5,330,474, etc.; for example US-5,257,994 using locking blocks designed to have specific angles, see Figure ia , ib and its description), to solve the above-mentioned spine joints are usually not parallel problems. However, these methods are only suitable for the fixation of the vertebrae between a fixed rod and two bone nails (because the two points are in line), but not for one fixed rod and three (including the vertebral joints above the y nail) Fixed, Ο Because the two points are usually not in line, in addition, after the operation, the affected part does not have the function of bending/twisting/stretching. 3. Universal joint device (universal) Connecting device), such as US-5,474,551, US-5,507,746, US-5,575,791, etc.; for example, US-5,474,551 utilizes a universal pad fixation device (see Figure ia, ib and its description). 'To solve the above-mentioned vertebral joints is usually not parallel. But these methods ❹ only apply to the fixation of the vertebrae between a fixed rod and two bone nails (because the two points are in line), but not for a fixed The rod and the three or more bones above the bone are fixed because the three points are usually not in line. In addition, the special method does not have bending after the operation. Twisting/stretching function 4. Solve problems with multi-axis screws (such as US-approved US-5,520,690, US-5,531,746, ...US-7) , 1%, 2552, US-7, 207, 992, etc. 39 and US related public patent applications US-20010012937, 6 200936097 US-200201 11626 '...' US-20070161995 'US-20070162006, etc. Twelve pens. This is the current mainstream technology. These technologies basically use multi-axis screws (see Figure la...that is, u, 6, 869, 4332, see the description of the details) to solve the above-mentioned spine joints. Not parallel issues.

The vertebrae are fixed because the three points are usually not on the straight line. Moreover, after the operation, the affected part does not have the function of bending/tWisting/stretching. 5. Solve the problem with an artificial joint fixture. For example, TW-I275380 (see Figure lb... Figure 5 of the case, see the description for details) to solve the problem that the above-mentioned vertebrae are usually not parallel. However, these methods also only solve the problem of spinal bone fixation between the two bone nails. The problem is that the problem of fixation of the spine joints above the three (including) bone nails cannot be solved and the ball of the upper rod (the case number 1〇) is connected in the case. The volume (labeled 102 in the case), and the ball joint connecting the lower rod (the symbol u of the case) (the combination between the labels of the case is not limited (4), which will cause the connection of the upper rod (the case number and the connection of the lower rod (this case) The angle between the case number n) is not fixed, that is, the solidity is poor. In addition, the methods do not have the function of (twisting)/stretching in the surgery m.
