Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
As shown in figure 1, foramen intervertebrale lens operation body surface targeting localised puncture device, including it is positioner, same with positioner
Step rotates the sting device of associated connection and is arranged on the pinion rotation adjusting means of positioner and sting device intersection.
Positioner include base 1 and base connecting plate 3 connected horizontally and with base location dimension connected vertically
Adjustable plate 2, connecting plate 3 be it is telescopic, can be with the cooperating therewith elongation of the length change of connecting rod 4 and shortening, correspondingly
Connecting rod 4 is also telescopic, and location dimension adjustable plate 2 is marked with scale, location dimension adjustable plate 2 and is parallel to each other and hangs down
There are the first bolt 5 of fixation, the second slideway 8 on first slideway 7 and the second slideway 8 on straight ground, the first slideway 7
On had the spiral shell for having had the effect of tightening on the second bolt 6 of fixation, the first bolt 5 and the second bolt 6
Mother, can be by 5,6 sizing on demand of bolt on slideway 7,8, and the first bolt 5 and the second bolt 6 are equal
Connecting rod 4 can be accommodated for hollow structure, in it to pass through, nearly gear end and first in pinion rotation adjusting means of connecting rod 4
Gear 9 is fixedly connected, and is synchronized with the movement.
Sting device includes trocar sleeve 13 and puncture needle 14, and the nearly gear end of trocar sleeve 13 is adjusted with pinion rotation to be filled
Second gear 10 in putting is fixedly connected, and is synchronized with the movement, and has puncture needle 14 to pass through in trocar sleeve 13, punctures direction with puncturing
The keeping parallelism of sleeve 13.
Pinion rotation adjusting means includes first gear 9 and second gear 10, and both close occlusal contact conditions are simultaneously opposed to same
Walk rotary motion, it is ensured that connecting rod 4 and trocar sleeve 13 keep symmetrical, and first gear 9 is fixed on by first gear rotary shaft 11
On connecting plate 3, second gear 10 is fixed on connecting plate 3 by second gear rotary shaft 12.
Implement before puncture procedure, the cross-section position picture of preferable centrum is chosen on CT or MRI pieces, canalis spinalis lower edge is measured thereon
A points to the distance between the small of the back skin 18 a, after measure the outer upper limb D points of intervertebral foramen to the distance between the small of the back skin 18 b,
When implementing puncture procedure, this sting device is positioned on the small of the back skin 18 parallel to intervertenral space direction, base 1 is placed on vertebra
The surface that body 15 is projected, adjusts the first bolt 5, position of first bolt 5 on the first slideway 7 is fixed on C
Point, it is ensured that C points to the distance between the small of the back skin 18 a ' are equal to a, similarly adjust the second bolt 6, make the second positioning spiral shell
Position of the bolt 6 on the second slideway 8 is fixed on E points, it is ensured that E points to the distance between the small of the back skin 18 b ' are equal to b.A, D two
Point determines straight line, and this straight line exactly punctures optimal channel, and at the same time straight line determined by 2 points of C, E is with base 1 and connects
The place plane of fishplate bar 3 is that the straight line of 2 points of determinations of symmetrical centre and A, D is symmetrical.At the same time, in mobile C, E 2,
Connecting rod 4 and connecting rod 3, which coordinate, does stretching motion.Trocar sleeve 13 is fixed for 2 points due to keeping symmetrical with connecting rod 4 as C, E
When, the place straight line of connecting rod 4 is it has been determined that the place straight line of trocar sleeve 13 also also determines that both are with first gear 9 and second gear
For symmetrical centre symmetrically, this ensures where trocar sleeve 13 plane perpendicular to plane where connecting plate where 10 midpoints
Straight line is overlapped with A, D straight line determined, exactly puncture channel, so when puncture needle 14 is punctured parallel to trocar sleeve 13
When, the passage that puncture needle 14 passes through is the destination channel of preoperative determination.
The present apparatus is directly placed on patient's the small of the back skin without extra fixing device when using, by certainly
Body gravity can keep stable.
Puncture needle is made up of titanium alloy, and other described each parts are made up of high polymer material, under being had an X-rayed immediately in art not
Very big interference can be produced to puncturing, and the present apparatus is small and exquisite, facilitates straight as aseptic apparatus when being operated in sterilization of instruments, art
Connect and operate with, that is, facilitate patient, be greatly reduced infection odds.
The utility model operating principle is：Two length according to obtained by preoperative Radiological measurement determine target puncture side
To, this direction is symmetric in the connecting rod in positioner, then where the direction in connecting rod is symmetric into trocar sleeve
Direction, symmetrical by converting twice, the signified direction of the trocar sleeve that can finally see in vitro is the mesh of preoperative determination
Direction is marked, necessarily can effectively be punctured according to this direction.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Any equivalent substitution, modification, improvement made within new spirit and principle etc., should be included in protection of the present utility model
Within the scope of.
