Abstract
The utility model provides a vertebral pedicle nail implanted angle guider, which comprises a positioning rod and two graduated right-angle fanning strips. The two fanning strips have a same centre of circle and are mutually vertically connected, wherein the positioning rod is connected to the fanning strips. The utility model overcomes the shortcomings of the prior art that the TSA and SSA are most determined by personal factor, the operation is complex and the monitoring device is expensive. Compared with the prior art, the utility model has the advantages of simple operation, accurate safety, low device demand and convenient application. The guider of the utility model can be applied to implanting vertebral pedicle nail and cervical aside rapid nail.
Description
Technical field
This utility model relates to a kind of medical operating apparatus, specifically is a kind of pedicle nail implant angle guider.
Background technology
It is the most frequently used technology that the spinal surgery pedicle screw is implanted, (horizontal plane advances to follow closely angle transverse screw angle to the TSA of correct definite pedicle of vertebral arch, leaning angle) and SSA (sagittal plane advances to follow closely angle sagital screw angle), accurately insert suitable pedicle screw, finish smoothly orthopedic, to reset fixedly be the successful key of operation.At present, because orthopaedics navigator costliness is difficult to popularize, the implantation of pedicle nail still is that armrest patient's experience is carried out entry point and the angle that pedicle nail is determined in range estimation in the art in most of hospital surgical, and anthropic factor is big, complex operation.
Summary of the invention
Goal of the invention of the present utility model provides a kind of accurate, safe pedicle nail implant angle guider.
The technical scheme that this utility model is dealt with problems is: comprise that a locating rod and two are with graduated right angle fanning strip, two concyclic hearts of fanning strip and vertical mutually the connection, locating rod is connected in fanning strip.
Be manufactured with the graduated disc and the graduation mark of 0-90 degree on the said fanning strip.
The long 8cm of said locating rod, an end are handle, and the other end is connected in fanning strip graduated disc 0 degree place.
This utility model has overcome that existing spine pedicle screws implanted prosthetics determines that TSA and SSA anthropic factor are big, the deficiency of complex operation and monitoring equipment costliness.Compared with prior art, this utility model safety easy and simple to handle, accurate, equipment requirements lower, be convenient to promote.Be applicable to cervical vertebra, thoracic vertebra, the implantation of the implantation of pedicle of lumbar vertebral arch screw and cervical lateral mass screw.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
In the accompanying drawing, comprise that a locating rod and two are manufactured with the graduated disc of 0-90 degree and the right angle fanning strip of graduation mark on it---first fanning strip 1, second fanning strip, 4, the first fanning strips 1, second fanning strip, the 4 concyclic hearts and vertical mutually the connection.Locating rod 2 long 8cm, an end is a handle 3, the other end is connected in first fanning strip 1, second fanning strip, 4 graduated discs, 0 degree place.
Using method of the present utility model and clinical practice: after determining entry point, sting cortical bone earlier except that the entry point place, the gag opening, this utility model locating rod 2 points are aimed at entry point, holding handle 3 by the assistant makes locating rod 2 perpendicular to the operating-table horizontal plane, second fanning strip, 4 plane parallel are in patient vertebral body both sides transverse process line, the doctor holds the angle that the device of exploring the way grasps before according to art and determines leaning angles by second fanning strip 4, determine that by first fanning strip 1 sagittal plane enters to follow closely the angle, the adjustment device angle of exploring the way, slowly enter, after detecting nail road wall obvious bone sexuality is arranged with probe, slow pedicle screw.
