Abstract
A kind of spinal surgery positioning guidance system, bilateral has three connecting rods respectively in frame structure, and the relativeness that is standard XYZ axle 90 degree in the three-dimensional system of coordinate is arranged, and can move.Three preceding image measurements according to three-dimensional reconstruction of connecting rod operation are determined the personalized length positional parameter of XYZ, determine the angle parameter of guide sleeve simultaneously.By preliminary setting parameter, become a kind of positioning guidance system of individuation and in operation, directly use, simplify operative procedure, shorten operating time greatly, reduce operation risk.
Description
Technical field the present invention relates to a kind of spinal operation positioning guidance system, especially can find the pedicle of vertebral arch inlet point quickly and easily rapidly in art and implant pedicle of vertebral arch, is expected to shorten greatly operating time, improves the operation accuracy rate.
Background technology is according to doctor's the different of proficiency level and the state of an illness complexity of patient own of performing the operation, and fault rate to a certain degree still can appear in free-hand implantation pedicle nail.More and more depend on the development of navigation system for the implantation of spine pedicle screws.Though navigation system the most commonly used both at home and abroad at present is the effect that the infrared navigation system can reach instant navigation in the art, but still exists the loaded down with trivial details and unskilled location that causes of service routine to be forbidden problem.The infrared navigation system still can not be able to extensive use clinical because of it costs an arm and a leg at present in addition.

Summary of the invention
The technical problem that solves
In order to overcome the deficiency that free-hand implantation internal fixation of spine exists, and costing an arm and a leg of existing of advanced infrared navigation, be difficult for shortcomings such as universal, the invention provides a kind of a kind of new spinal location of operation guidance system of rebuilding based on multidimensional image before the art, this system can not only quick and precisely locate pedicle of vertebral arch and implant point, can also guide pedicle of vertebral arch to press correct angle and implant.The more present state-of-the-art infrared navigation of this system system compares and also has easy to usely simultaneously, is easy to advantages such as popularization.
Technical scheme
The technical solution adopted for the present invention to solve the technical problems is: according to the anatomy of spine characteristics, research and develop a kind of general adjustable three-dimensional localization guidance system of parameter.This system comprises the spinous process clamp centre of location, the adjustable measuring stick of bilateral horizontal cross, the vertical adjustable measuring stick of bilateral level, the vertical adjustable measuring stick of bilateral and pedicle of vertebral arch implantation guide sleeve.Each measuring stick connects by 90 degree.Wherein the spinous process clamp centre of location comprises spinous process clamp fixture again, spinous process sagittal plane positioning needle, spinous process coronalplane angle positioning device three parts.According to single vertebral body registration principle, before spinal operation, use three-dimensional reconstruction software, rebuild spine image, with behind the spinous process following be reference point, determine the three-dimensional localization point (x, y, three parameters of z) of single vertebral body bilateral pedicle of vertebral arch.According to the measurement of axle position and sagittal plain, determine the outer drift angle that pedicle of vertebral arch enters and vow the drift angle simultaneously.According to the individual patients data parameters of being surveyed, position guiding device is carried out setting before the art, make it to become personalized positioning guidance system.After only needing in the art accurately to locate the spinous process reference point, can determine pedicle of vertebral arch inlet point and admission passage rapidly.
Beneficial effect
The invention has the beneficial effects as follows, can simplify operative procedure, when shortening operating time, accurately locate the pedicle of vertebral arch inlet point and enter angle, quick and precisely implant the spinal column pedicle of vertebral arch.This system also has simple in structure, is easy to advantages such as use.

The specific embodiment
In Fig. 1, the spinous process clamp centre of location (1) is the match point of the native system and the vertebral body spinous process back lower place, and horizontal cross is adjustable, and right (6) level in a measuring stick left side (2) is stretched out to both sides, and measuring stick carries scale; The vertical adjustable rod of a level left side (3) right (7) is 90 degree with the horizontal cross adjustable rod, and level is vertically stretched out, and carries scale on the measuring stick; And a vertical adjustable measuring stick left side (4) right (8) are 90 degree vertically downward with the vertical adjustable measuring stick of level; Implant a guide sleeve left side (5) right (9) in the terminal pedicle of vertebral arch that connects of vertical adjustable measuring stick.
The data that obtain according to three-dimensional reconstruction before the operation, with behind the spinous process following be reference point, determine the three-dimensional localization point (x, y, three parameters of z) of single vertebral body bilateral pedicle of vertebral arch, adjust the right side, the adjustable measuring stick of a horizontal cross left side (2) (6) respectively; The vertical adjustable rod of a level left side (3) right (7); A vertical adjustable measuring stick left side (4) right (8); According to the measurement of axle position and sagittal plain, determine that pedicle of vertebral arch enters the outer drift angle on a sleeve left side (5) right (9) and vows the drift angle simultaneously.
In Fig. 2, after the spinous process clamp centre of location and the vertebral body spinous process back lower place match point coupling, adjust sagittal positioning needle (16) in vertebral body spinous process sagittal plane, regulate spinous process and press from both sides horizontal adjustable rod (12), make spinous process folder fixation side (14) and spinous process press from both sides adjustable side (15) and clamp spinous process.Device fixing errorless after, the corresponding position, lower end of the vertical adjustable measuring stick of a bilateral left side (4) right (8) is the pedicle of vertebral arch inlet point.
Pedicle of vertebral arch can be implanted pedicle screw safely by implanting right (9) direction in a guide sleeve left side (5).
