Description
Technical field
Medical aid is the utility model is related to, especially a kind of fracture of lumbar vertebra percutaneous reduction by leverage locator.
Background technology
Now with the industrialized fast development of society, due to the high speed development of the technologies such as traffic, building, spine fracture
Gradually increase trend is also presented in morbidity, meanwhile, with social population's aging, due to being fractured increasingly caused by osteoporosis
It is more.The titanium net reconstruction or the strong fixation of nail-stick system of the way of escape on the main You Qian roads for the treatment of for fracture of lumbar vertebra at present.For bone
The lumbar vertebrae of folding is substantially carried out the distraction reduction of nail-stick system in the case of soleplate is unspoiled.But the distraction reduction of nail-stick system is past
It is past to be unable to reach preferable reset standard, and applied in sufferers of osteoporosis face and be relatively easily caused fixed-segment vertebral fracture.
In the last few years, the method that fracture percutaneous reduction by leverage is combined on the basis of operative reduction is preferably developed, this
Percutaneous reduction by leverage punctures inserting needle using traditional pedicle of vertebral arch position, into hindering after vertebra centrum in centrum, according to spinal surgery
The experience combination CT images of doctor, carry out percutaneous reduction by leverage.
But carry out in centrum sled in this way and dial, the position of collapse of vertebra can not be reached and be accurately positioned, prized
Dial point to compare blindly, be unable to reach good percutaneous reduction by leverage effect, and the angle grasp to inserting needle is not accurate enough, is easier to penetrate
Canalis spinalis, injured nerve, or into abdominal cavity, abdominal aorta or abdominal viscera are punctured, serious consequence is brought, and due to positioning not
Accurately, operation time extends, increase operation relevant risk.
In order to avoid the spots localization to collapse of vertebra is inaccurate, blindly sled is dialled, puncture needle penetrates canalis spinalis, injured nerve,
Into abdominal cavity, the serious consequence such as abdominal aorta or abdominal viscera is punctured.Strengthen the positioning accuracy that sled dials point, shorten operation behaviour
Make the time, reduce relevant risk after surgery.We design a kind of adjustable " waist by studying and putting into practice for a long time
Vertebra folding percutaneous reduction by leverage locator " solves these problems that lumbar vertebrae bone surgery is brought.
The content of the invention
The purpose of this utility model is to provide a kind of fracture of lumbar vertebra percutaneous reduction by leverage locator, solves existing current collapse of vertebra
Position position inaccurate, blindly sled dial easily occur operation it is unexpected the problem of.
To achieve the above object, technical scheme is used by the utility model：A kind of fracture of lumbar vertebra percutaneous reduction by leverage positioning
Device includes scale, fixator, locator；The scale is provided with angle index and length scale using intermediate point as zero point；Institute
State fixator bottom and be provided with the groove being adapted to the spinous process of fractured vertebral body, it is solid that the fixator is provided with first led in groove
Determine screwed hole, the upper end of the fixator, which is provided with, is adapted to the first chute with scale, and the fixator, which is provided with, leads to the first chute
The second interior fixing screwed hole；The locator includes positioning sliding block, angle pilot pin, and the positioning sliding block is provided with and mark
Chi is adapted to the second chute, and the positioning sliding block is provided with the 3rd fixing screwed hole led in the second chute；The angle
Pilot pin is provided with protruding shaft and is hinged by protruding shaft and positioning sliding block, and the angle pilot pin axial centre is provided with leads to for puncture needle
The through hole crossed.
The groove inner wall of the fixator is provided with some bulge-structures being evenly arranged.
The fixator is provided with the peep hole led in the first chute.
It after the utility model uses said structure, can not only be accurately positioned, blindly sled group be avoided, so as to improve operation
Security, while operative speed can be accelerated, the time is reduced, reduces operation risk.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
A kind of as illustrated, fracture of lumbar vertebra percutaneous reduction by leverage locator, it is characterised in that：Including scale 1, fixator 2, positioning
Device 3；The scale 1 is provided with angle index and length scale using intermediate point as zero point；The bottom of fixator 2 is provided with and bone
The groove 21 of the spinous process adaptation of centrum is rolled over, the fixator 2 is provided with the first fixing screwed hole 23 led in groove 21, described
The upper end of fixator 2 is provided with and be adapted to the first chute 22 with scale 1, the fixator 2 provided with lead in the first chute 22 the
Two fixing screwed holes 26；The locator 3 includes positioning sliding block 31, angle pilot pin 32, and the positioning sliding block 31 is provided with
The second chute 311 is adapted to scale 1, the positioning sliding block 31 is provided with the 3rd fixing screwed hole led in the second chute 311
312；The angle pilot pin 32 is provided with protruding shaft 322 and is hinged by protruding shaft 322 and positioning sliding block 31, and the angle is determined
The position axial centre of pin 32 is provided with the through hole 321 passed through for puncture needle.
Before operation, according to the imaging data of patient, under the guidance of 3D printing technique, puncture is oriented
Point, angle, the depth of puncture are calculated, accurately draws point of puncture and puncture angle.
During operation, the first step is to be stuck in fixator 2 on the spinous process of fractured vertebral body by groove 21, and is worn by screw
The first fixing screwed hole 23 is crossed to fix；
Second step is that scale 1 is passed through into the first chute 22, and scale zero graduation is moved into point of puncture according to preoperative data
Surface, and pass through the nonadjustable signal 1 of the second fixing screwed hole 26 using fixed screw；
3rd step is to be arranged on locator 3 on scale 1 by the second chute 311 of positioning sliding block 31, and slides onto art
On the respective angles position that preceding data are specified, fixed with screw through the 3rd fixing screwed hole 312, then adjustment angle pilot pin
32 match with the angle index on scale 1；
Final step is exactly that puncture needle is penetrated into collapse of vertebra position through the through hole of angle pilot pin 32, carries out sled and dials again
Position.
It using fracture of lumbar vertebra percutaneous reduction by leverage locator, along with above-mentioned steps, can not only be accurately positioned, avoid blindly prizing
