Abstract
A percutaneous lumbar vertebra foramen intervertebrale endoscope puncture locator is composed of a fixed support, a triple-action connector, a parallel adjusting rod, a puncture guide plate sliding base, a puncture guide plate, a fixed locating pin and a sliding locating pin. The puncture locator has the advantages that on one hand, whether an obstacle and a puncture target exist in a puncture path or not is determined by using images of the C arm perspective fixed locating pin during an operation, whether the bottom edge of a virtual triangle and the puncture target are on the same plane or overlap is determined by using the position of the C arm perspective sliding locating pin, and puncture accuracy is improved through front side location of the fixed locating pin and the sliding locating pin; on the other hand, only the puncture angle needs to be measured before the operation and changes little along with the body position, so that variable parameters are reduced, and errors are reduced.
Description
Technical field
The present invention relates to a kind of operating theater instruments, be specifically related to a kind of through skin lumbar intervertebral aperture mirror puncture locator.
Background technology
Existing through skin lumbar intervertebral aperture mirror puncture locator, formed by fixed support, vernier protractor, intervertebral foramen locating piece, range measurement bar, puncture sleeve, compasses etc. Before operation in patients, CT sheet bone window is gone up mutually, utilizes right angle trigonometry function principle to measure puncture angle, paracentesis depth, point of puncture to spinous process distance. There is three aspects: shortcoming in the practical operation in art of such DATA REASONING: on the one hand, in art, cannot measure intervertebral foramen locating piece to vertical depth between intervertebral foramen, so blindly operation exists predetermined design puncture path to change to vertical depth between intervertebral foramen with intervertebral foramen locating piece. In addition on the one hand, before operation in patients, CT is that horizontal position does, and in art, patient is prone position, and waist measurement parameter changes with position, the limit that in art, restive range measurement bar is parallel to preoperative CT design right angle trigonometry causes puncture angle error, and the preoperative data of horizontal position CT reference value in art declines. Secondly, utilize right angle trigonometry function principle to measure puncture angle, paracentesis depth, point of puncture to spinous process distance, need to adjust puncture angle or other parameters if one-time puncture is unsuccessful, in art, need to utilize trigonometric function principle calculating puncture angle, paracentesis depth, the point of puncture of trouble to give adjustment piercing process to spinous process distance, adjustment process complicated and time consumption is many, needs auxiliary calculating under platform need to adjust data. This inconvenient operation, not only increases operating time, easily causes putting that instrumentation tubes position is undesirable causes that surgical effect is bad, and perspective increases doctor, patient's amount of radiation repeatedly.
Summary of the invention
In order to overcome the above-mentioned defect of above-mentioned prior art, the invention provides a kind of through skin lumbar intervertebral aperture mirror puncture locator.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Invention, through skin lumbar intervertebral aperture mirror puncture locator, is made up of fixed support, three moving linkers, parallel adjusting rod, puncture guide plate sliding bottom, puncture guide plate, stationary positioned pin, slip pilot pin.

Three described movement connector far-ends are socketed parallel adjusting rod, parallel adjusting rod link puncture template sliding bottom. Described two pieces of locking nails of puncture guide plate sliding bottom band, wherein one piece of locking nail control sliding bottom is in the position of parallel adjusting rod, other one piece of direction of rotation of controlling puncture guide plate. Described puncture guide plate link puncture guide-board base.
Further, on puncture guide plate, establish stationary positioned pin hole, slip location pin hole and the different angles puncture pilot hole of puncture target spot location. Wherein stationary positioned pin, slip pilot pin are isometric.
Further, the stationary positioned pin hole on puncture guide plate is installed stationary positioned pin hole, and it can not slide after installing, at back localizing objects puncture target spot. The location pin hole that slides is installed the location pin hole that slides, and it can slide after installing, at side localizing objects puncture target spot. The design of puncture pilot hole taking slip pilot pin right angled triangle base, puncture guide plate is as right angled triangle opposite side, puncture path are hypotenuse composition right angled triangle, designs 18 the guide plate holes consistent with puncture path according to puncture angle by 10 ° to 45 ° at interval of 2 ° on puncture guide plate.
Further, puncture guide plate according to different patient's builds need to be divided into little, in, large three kinds of models puncture guide plate, small size puncture guide plate is the puncture pilot hole in 15cm runners according to stationary positioned pin length. Medium size puncture guide plate is the puncture pilot hole in 18cm runners according to stationary positioned pin length. Large size puncture guide plate is the puncture pilot hole in 21cm runners according to stationary positioned pin length.
The invention has the beneficial effects as follows: on the one hand, in art, utilizing " C " arm perspective stationary positioned pin image to determine whether puncture path exists stops and puncture target spot, utilize " C " arm perspective slip pilot pin location positioning virtual triangle base and puncture target spot at same plane or overlapping, improve puncture accuracy through stationary positioned pin, the positive side of slip pilot pin location. On the one hand, preoperative needs are measured puncture angle in addition, and puncture angle is little with Body Position Change, reduce changeability parameter and reduce error. Secondly, Fluoroscopy location target spot can be punctured to because of the each pilot hole of guide plate, puncture angle need to be adjusted if one-time puncture is unsuccessful, directly select different angles puncture pilot hole just can according to situation in art, need not calculation of complex parameter, save operating time, reduce perspective number of times.
