Description
Technical field
The present invention relates to medical apparatus and instruments, particularly relate to cross-connecting apparatus between a kind of pedicle of vertebral arch, and the spine correcting system that constitutes by cross-connecting apparatus between pedicle of vertebral arch.
Background technology
When carrying out spinal column orthopedic at treatment spinal disease (for example scoliosis, dislocation etc.), present Therapeutic Method is an anchoring nail on the pedicle of vertebral arch of the vertebra both sides of needs treatment, to be connected up and down then, each nail of the same side of the pedicle of vertebral arch of vertebra utilizes connecting device to connect along the vertical direction, by connecting device make be connected up and down the nail of the pedicle of vertebral arch of vertebra reset fixing, thereby reach orthopedic effect to spinal column.This orthotic device and method can play certain therapeutic effect, but still have many disadvantages:
1) in orthopedic process, physiological situation based on human body, on each joint vertebra, angle between the pedicle of vertebral arch of both sides increases gradually along with from top to bottom direction, for example at the vertebra of spinal column upper end, angle between the pedicle of vertebral arch of its both sides is near 0 degree, and then along downward direction, it is 5 degree, 10 degree that the angle between follow-up supraspinal pedicle of vertebral arch increases gradually ...Angle maximum between the pedicle of vertebral arch can reach about 35 degree.In near 0 excursion of spending to about 35 degree, the nail on the same side pedicle of vertebral arch of vertebra up and down can not form straight line along the vertical direction.For nail is coupled together, can only make the connecting device bending, connecting device is bent to complicated irregular curve through regular meeting, and this brings huge difficulty to connecting so that carry out orthopedic work by nail of vertebra about the connecting device general.Particularly, because the pathological changes of patient's spinal column distortion, can cause the line between the connection end of the nail on the same side pedicle of vertebral arch that is connected vertebra up and down to become complicated space curve (seeing also shown in Figure 21), this gives and utilizes connecting device that the work that the connection end of nail connects is brought further difficulty.And in operation process, the connection work of this complexity has increased operating time and operating difficulty greatly.
2) in orthopedic process, for up and down between the vertebra along the dislocation of fore-and-aft direction, need apply pulling force to the connection end of the supraspinal nail of dislocating by connecting device, the vertebra of dislocation is resetted.Yet when resetting, required pulling force is very big, in case be fastened on bed knife on the pedicle of vertebral arch greater than nail, the situation that nail is pulled on pedicle of vertebral arch can take place, and causing reset failure even operative failure, causes suffering to patient.
