Embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
Embodiment：The quick servicing unit for determining puncture path, its structure such as Fig. 1-4 in a kind of operation for spinal puncture
It is shown, including：Main body frame 1, main body frame 1 is the rigid material through x-ray.The bottom of main body frame is upper with support bar 7
End is fixedly connected, and puncture needle locator 3 is provided with main body frame 1.
Four sidepieces of the main body frame 1 have X to bar-shaped trough 11 and Y-direction bar-shaped trough 5, the bar shaped in each direction respectively
Groove is 2；
X is provided with X into bar-shaped trough 11 to slide bar 4, is provided with Y-direction slide bar 2 in Y-direction bar-shaped trough 5, and X is to slide bar 4 and Y-direction
Slide bar 2 is through the puncture needle locator 3；
Wherein, positioning waffle slab 9 is also plugged with the Y-direction bar-shaped trough 5；
The first scale neck 9-1 and the second scale neck 9-2 are provided with positioning waffle slab 9.Waffle slab 9 is positioned to stop
The rigid metallic material of x-ray, main body is fixed into square net tabular, sizing grid, can be identical with the larger unit scales of scale.
Meanwhile, X is threadedly coupled with X to positioning knob 10 respectively to the two ends of slide bar 4, the two ends of Y-direction slide bar 2 respectively with Y
It is threadedly coupled to positioning knob 6.
Specifically, puncture needle locator 3 is the rigid material through x-ray, mainly includes installing in sliding block 3-1, sliding block
There are rotating disk 3-2, sliding block 3-1 and rotating disk 3-2 interference fit；Place kick 3-6 is provided with rotating disk 3-2, place kick 3-6 covers with puncturing
Pipe 3-3 is fixedly connected, and place kick 3-6 both sides are fixedly connected with rotating bar 3-4 respectively, and rotating bar 3-4 matches somebody with somebody with rotating disk 3-2 interference
Close, rotating bar 3-4 is rotated relative to rotating disk 3-2.For the ease of being relatively fixed rotating disk 3-2 and sliding block 3-1,
Screwed hole 3-7 is provided with sliding block 3-1.
Fixed for the ease of puncture cannula 3-3, two arcs locating rod 3-5, puncture cannula 3-3 are installed on rotating disk 3-2
Between two arc locating rod 3-5, then by puncture cannula 3-3 and arc locating rod 3-5 frictional force, it is allowed to keep phase
To fixation.
Scale is set on main body frame 1, can be positioned with auxiliary slider 3-1.
The use process of the present apparatus is as follows：
Before perspective, first puncture needle locator 3 is placed on an angle of main body frame, then rotational positioning knob prevents it
It is mobile.Support bar 7 is fixed on the side rails of operation table two by lock device again, to avoid the rolling due to being brought in puncture process
It is dynamic.
Before positioning, scale is vertically caught in the first scale neck 9-1, (i.e. side position is had an X-rayed along A directions shown in Fig. 5
Perspective), x-ray image is obtained, a vertical line is drawn on image as reference line, then draws first oblique line as drafting puncture
The intersection of path, first oblique line and scale is Y-coordinate, and the angle of oblique line and vertical line is β angles.
Next, scale is placed horizontally in the second scale neck 9-2, had an X-rayed (i.e. just along B directions shown in Fig. 4
Position perspective), x-ray image is obtained, then using Y-coordinate as horizontal line of pointing with the finger or gesticulate out on image, obtains designing the X of puncture path intersection point
Coordinate, and measure design puncture path and vertical line angle α, then preposition measurement work is completed.
Then, positioning waffle slab 9 is dismantled with scale, loosens four positioning knobs, move sliding block 3-1 geometric center
To X-coordinate and Y-coordinate, and it is identical with β angles to rotate rotating disk 3-2 adjustment puncture cannula 3-3 angle, is then screwed into using bolt
Screwed hole 3-7, reaches the purpose for holding out against rotating disk 3-2.The motionless rotational positioning ball 3-6 of rotating disk 3-2 are kept to make puncture cannula 3-3's again
Angle is identical with α angles, is relatively fixed puncture cannula 3-3 and arc locating rod 3-5 using devices such as buckles.
As shown in fig. 6, puncture cannula 3-3 axis (dotted line in Fig. 6) is design puncture path.
Employ after said structure, the present apparatus can in art relatively rapid accurate determination puncture path, and to puncture
Apparatus such as puncture needle etc. provides the less puncture channel of deviation.By puncturing preceding x-ray normotopia and side position, 2 perspectives can be true altogether
Fixed relatively accurate puncture path, can be according to the puncture path determined using puncture cannula after puncture path is determined
Complete to puncture with minimum deflection.
Still there is deviation after such as puncturing, can be finely adjusted.In the ideal situation, it is possible to decrease X-ray examination number of times to 2 times, pole
Big reduces operating time and puncture time, reduces pain and the x-ray open-assembly time of patient.
