Description of the Invention: [Technical Field of the Invention] The present invention relates to a splint coupling device, and more particularly to an adjustable angle spinal rod connecting device. [Prior Art] In the spinal fixation surgery, the fixed rod is often used as an auxiliary fixation device, but because the spine is not in a straight line, the vertebrae are usually not parallel, for example, the lumbar vertebrae are the sacral bulge (10) d〇sis) so if the original is - The linear fixing rod is directly integrated with the multiple bone nails implanted in the vertebral joint to be fixed, which will force the vertebral bones to be fixed in the line and the line to be in a straight line, and the respective bones to be fixed which should not be parallel The festival becomes parallel. In order to avoid such a deficiency, the medical community has proposed various improved structures, such as: 1. Solving problems with angled screws such as us_ 5,176,679, US-5'196,014, US-5,257,994, US-5,466,238, etc.; For example, US-5,176,679 utilizes angled nails (h) cking pins designed to have specific angles, to solve the above-mentioned problem that the vertebrae are generally not parallel. 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 or more bones above the bone. Fixed because the three points are usually not in line. In addition, after the operation, the affected part does not have dynamic functions such as extension, flexiform, lateral bending, and axiai. Torsion) and buffer (cushi〇n) 201212875 ° function. 2. Solve the problem with an angled connector such as US-5,257,994, US-5,330,474, etc.; for example, uS-5,257,994 uses locking block designed to have specific angles to solve the above-mentioned vertebrae Sections are usually not parallel issues. 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 line, _ In addition, 'these methods do not have dynamic functions in the affected part after surgery, such as extension, flexi〇n, iateral bending, torsion ( Axis torsion) and buffer (cushion) function. 3. Solving problems with a 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. Solve the above-mentioned spine joints usually and φ non-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 or more bones above the bone. Fixed because the three points are usually not in line, and in addition, 'these methods do not have dynamic functions after surgery, such as extension, flexion, lateral bending, and axial torsion. Wait and buffer (cushi〇n) function. 4. Solve problems with polyaxial screws, such as US approved patents US-5,520,690, US-5,531,746, ...US-7,186,2552 'US-7,207,992, etc., and The United States related public patent applications 201212875 US-20010012937, US-20020111626, ·..·., US-20070161995, US-20070162006 and so on. This is the current mainstream technology. These techniques basically utilize multi-axis screws (see the specification for details) to address the problem that the above-mentioned vertebrae are generally not parallel. However, the above-mentioned special method is only suitable for the fixation of the vertebrae between a fixed rod and two bone nails (because the two points are in line), but it is not suitable for a fixed rod and three (including) vertebrae above the bone nail. The section is fixed because the three points are usually not in a straight line. In addition, after the procedure, the affected part does not have dynamic functions such as extension, flexiform, iateral bending, and torsion ( Axis torsion) and buffer (cushion) function. 5. Solve the problem with an artificial joint fixture, such as TW-I275380 (see the instructions for details) to solve the problem that the above-mentioned vertebrae are usually not parallel. These methods have dynamic functions such as extension, flexion, lateral bending, and axial torsion after surgery. However, the design is poor in stability and has the risk of loosening. Sex also takes up a lot of space, and the design also has no buffering (cushi〇n) function. The inventor's Taiwan patent TW-200936097 utilizes a ball arc device and an elastic design to make the spinal fixation rod simultaneously have the above-mentioned dynamic functions such as extension, flexion, lateral bending, and torsion ( Axial torsion) and cushioning function, but the patent uses an additional coupling device to connect the first cup to the second cup. Thus, the spinal fixation device will require more space for surgery Less inconvenient and consume 201212875 1 time. The invention adopts the ball arc mechanism with the ball arc mechanism and the ball joint mechanism of the first connecting rod and the connecting end of the first connecting rod, so that the two adjacent connecting rods can be adjusted by the gasket with the ball arc mechanism. The purpose of the angle between adjacent connecting rods and the invention has the dynamic functions of extension, flexior, lateral bending, and axial t〇rsi〇n, and The invention also utilizes the design of the elastic spacer to make the spinal rod connecting device have the cushion function at the same time, and the invention also adopts the design of the self-joining between the two connecting cup bodies, thereby reducing the spinal rod connecting device. The disadvantages of the inventor's Taiwan patent TW-200936097 are solved by reducing the required space at the same time. The invention can further limit the adjustable angle of the two adjacent connecting rods by the size of the perforations of the disc-shaped elastic piece, the connecting rod and/or the connecting cup body, so that the angle between the two adjacent connecting rods is not excessively large. It can not be recovered: or destroy the structure of the connecting rod, thereby affecting the function of the bone fixing system. SUMMARY OF THE INVENTION It is an object of the present invention to provide a spinal rod coupling device. Another object of the present invention is to provide a spinal rod attachment device having a sepal. A further object of the present invention is to provide a device connecting device having an elastic cymbal. CONNECTION DEVICE A further object of the present invention is to provide a spinal rod having a disc-shaped elastic piece. 201212875, the purpose of which is to provide a spinal rod coupling device in which the coupling cup is self-joined. Another object of the present invention is to provide a spinal rod coupling device that utilizes a ball arc structure to form a universal joint. A further object of this month is to provide a ridge pusher attachment device having an elastic function. Still another object of the present invention is to provide an adjustable angle spinal rod coupling device. Still another object of the present invention is to provide a limited degree of control adjustment of the spinal rod coupling device.
