The development of operation, it is minimally invasive to put nail, precisely put to have followed closely into spinal surgery and obtain mainstream development direction.It is minimally invasive to put nail, precisely put nail
Matter of utmost importance be the problem of boring positioning to be solved is accurate, boring positioning is accurately minimally invasive to put nail, precisely put nail success
Key, also one of most difficult link.But existing surgical procedure is completely dependent on the manipulation of patient, to the technology of patient
It is required that high, whole process is required in art carry out under the monitoring of x-ray, and the ray exposure to medical personnel is excessive.At present, state
Outer research and development have the navigation equipment of correlation, but there are problems that equipment volume is big, complicated, price, it is difficult to therefore need badly
There is the spinal surgery angle guider that a kind of simple in construction, cost is low.
Utility model content
The purpose of this utility model is that there is provided a kind of simple in construction, cost in order to overcome the shortcomings of prior art presence
Low spinal surgery angle guider.
To achieve the above object, the utility model provides following technical scheme：A kind of spinal surgery angle guider,
It is characterized in that：Including support and guider body, column of the support provided with horizontal gird and two ends, horizontal gird upper table
Face is provided with distance scale line along its length, and the lower end of the column is provided with the structure with operation table slide fit, the guider sheet
Body includes a measurement ball, sphere installation seat and base, and the measurement ball center is provided with and passing through that Kirschner wire diametric clearance coordinates
Through hole, measurement ball surface is provided with longitude graduation mark and latitude graduation mark around through hole, and the sphere installation seat is circular structure
Part, thickness is 2nd/1st to three/3rd of the measurement bulb diameter, and the inner hole wall of sphere installation seat is and measurement ball surface
The spherical concave surface of ring-type being adapted, the measurement ball can be rotatably set in the endoporus of sphere installation seat, the sphere installation
One side end face upper measurement of seat is provided with radial angle graduation mark around endoporus, and the measurement ball is arranged on base together with sphere installation seat
On, sphere installation seat is into erectility, and the base is slidably disposed on the horizontal gird of the support, and provided with lock
Determine mechanism.
Further set as the utility model, the sphere installation seat includes annular ball seat, ball seat shell and cover plate, annular
It is the spherical concave surface of ring-type being adapted with measurement ball surface that ball seat, which obtains inner hole wall, is merged by two semicircular rings and formed.
The utility model on support by setting the measurement that the spheroid for being carved with longitude graduation mark and latitude graduation mark is constituted
Ball and the circular sphere installation seat for being provided with radial angle graduation mark around endoporus on end face.In use, Kirschner wire is inserted
, can be in Three dimensional rotation measurement ball regulation angle, according to longitude graduation mark and latitude graduation mark and radial direction into the endoporus of measurement ball
Relative position between angle index line, you can draw the left and right drift angle of Kirschner wire and the oblique angle with horizontal plane, you can guiding hand
The progress of art.The present apparatus have it is simple in construction, it is easy to operate, it is with low cost, to patient require be greatly lowered, be easy to promote.
Below in conjunction with the accompanying drawings and specific embodiment is further described to the utility model.
