And various navigation systems which are newly raised in recent years are expensive, complex to operate and difficult to popularize in primary hospitals.
At present, aiming at the problems, the prior art mainly adopts a simple auxiliary positioner, the simple auxiliary positioner is fixed beside an operation bed or directly fixed on the body surface by hands, an abduction angle and a head inclination angle are calculated according to data provided by preoperative CT or MRI, and then a guider is well arranged according to the measured abduction angle and the measured head inclination angle so as to reach a preset puncture position. Although these auxiliary localizers reduce the puncture and fluoroscopy times and improve the puncture success rate, there are still some problems: for example, the volume is large and the installation is complicated. Secondly, some positioners need to be adjusted repeatedly under the perspective of the C arm in the process of establishing the puncture path. And thirdly, the development of the positioner influences the relevant tissues of the lumbar vertebra during the positive lateral perspective, thereby influencing the puncture process. Fourthly, the positioner is fixed beside the operation bed or on the body surface, and the positions of the positioner and the target point of the pathological change are easily influenced by the body position.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a single-cone three-point fixed intervertebral foramen puncture guider, which mainly solves the following technical problems: reducing X-ray fluoroscopy times in the puncture process. And the influence of the development of the positioner on the puncture process in the perspective process is reduced to the maximum extent. Solving the problem that the relative position of the positioner and the lesion target spot is easily affected by the body position.
The technical scheme for achieving the aim of the utility model is that the single-cone three-point fixed intervertebral foramen puncture guider comprises a fixed block, wherein a support is arranged on the fixed block, a positioner main body is connected onto the support, the positioner main body comprises a sliding frame, a 90-degree protractor and a 90-degree sliding rod, one end of the sliding frame is connected with the support, the other end of the sliding frame is connected with the 90-degree protractor, and the 90-degree sliding rod is vertically connected with the 90-degree protractor; and a puncture guide cylinder is further fixed on the 90-degree protractor, and a sliding block is further arranged on the sliding frame.
In a further improvement, the 90-degree protractor is an 1/4 arc protractor, and an arc groove is arranged on the 90-degree protractor.
The further improvement is that a 90-degree slide rod is arranged in the arc groove of the 90-degree protractor.
In a further improvement, the 90 ° slide bar is an 1/4 arc slide bar.
In a further improvement, the 90 ° protractor is also connected with the slide block.
The further improvement is that the fixing block is provided with a hole core.
The utility model has the advantages of small volume and simple assembly. Each component of the puncture outfit is small in size and simple in structure, shielding is reduced, and the influence of development of the positioner on the puncture process during perspective can be reduced to the maximum extent. When the positioner main body is used, the fixing block can be fixed on the spinous process and the transverse processes on the two sides, so that the position of the positioner and a lesion target point are relatively constant, and the problem that a puncture path changes along with the body position is solved.
