1333850's ._;7 Correction replacement page VI. Description of the invention: [Technical field to which the invention belongs] The special uncovered end is a ridge of titanium which is solidified and can be divided into two types of titanium. The present invention relates to a kit flexible cable spinal fixation device, and a flexible cable having an original flexibility that can be covered by a plurality of clips without a flexible section or a cover section. The kit is adjacent to a pair of flexible cable spine fixtures that are connected to each other with a variable angle. [Prior Art] If the traditional spinal injury is fixed by the nail and the connecting rod, the fixed link of the gold or the non-pound steel is combined with the multiple branches implanted in the vertebrae of the vertebrae. The method of forcibly connecting the fixation requires the determination of the damaged vertebrae. However, such a hard and hard way to forcibly fix, in addition to the inability to provide appropriate force to eliminate 'can not cause fretting stimulation of the damaged vertebrae, to promote the stability of the damaged part of the bone, so that the patient is in a bed or back frame for a long time The state of support cannot properly restore the function of the spine as quickly as possible. If there is only a cable-type connecting rod connecting the nails between the nails, there is a major problem. The first is that the cable-type connecting rod is too rigid, and it is no different from the above-mentioned metal-transferred or stainless steel straight-shaped connecting rod. If the cable type link is soft, it is unable to provide proper supporting force, and the cable is easily deformed. If a support tube is jacketed on the cable, there will be loss of the property of providing flexibility, elasticity or curvature. This is no different from using a connecting rod.
