Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of slippage vertebra restorer.
Background technique
At present when the illness such as treatment spinal injury, slippage, common treatment method is will using vertebral fixity system
The corpus vertebrae replacement of sliding simultaneously carries out intervertebral fusion and fixes, final to restore the normal Axial symptoms of vertebra and line of force relationship, releases
To the drawing and compressing of nerve root.In the course of surgery, good reset can be depressurized effectively, restore the backbone physiology of patient
Curvature.But the centrum actually slipped often resets difficulty, and most important difficulty is that centrum intervertebral contacts when carrying out corpus vertebrae replacement
The comparative resistance at position is larger, and the strength for relying only on pedicle screw is resetted to vertebra is slipped, and is easy to cause the loosening of screw, pulls out
Out, cause to reset and fail.In order to effectively be strutted to slippage gap, vertebral arch nail system is made effectively to play lifting effect, China
Patent CN201279177Y discloses a kind of slide rail type intervertebral spreader, including handle, lower distraction plate and upper distraction plate, under described
Distraction plate is equipped with sliding rail, and it is to be slidably matched between two distraction plates, distraction plate assembles that upper distraction plate, which is equipped with groove engaged therewith,
It is connect afterwards with removably handle.In reseting procedure, slippage vertebra tightly rides in upper and lower two with its next centrum respectively and struts
On plate, then handle is taken, screws lifting nail nut, under the lifting effect of pulling nail, by between two distraction plates
The effect of guide rail carries out lifting reset to vertebra is slipped.The intervertebral opening device needs to combine closely just with slippage vertebra and the next centrum
It can play a role, vertebra is slipped when binding force is too small to form one with intervertebral pulling, can not be fought distraction plate and be strutted under
Binding force between plate, and can not play a role；Binding force is excessive, can damage the sclerotin of contact surface, influence Invasive lumbar fusion device with
The syncretizing effect of bone.
Summary of the invention
The purpose of the present invention is to provide a kind of restorers, and insertion slips vertebra and lower cone in slipping vertebra reseting procedure
And/or between upper centrum, the frictional force slipped between vertebra and adjacent vertebral is reduced, reduces the resistance of pulling nail lifting process, guarantees to slide
De- vertebra reset effect.
Vertebra restorer is slipped, including outline border and roller bearing, outline border include upper ledge, lower frame, left frame and right frame, roller bearing is parallel
For arranged distribution in outter frame shelf and roller bearing diameter is greater than frame thickness, two sides are higher by outline border, one end of the first connecting shaft with
One end of left frame connection, the other end and roller bearing connects, and one end of the second connecting shaft is connect with right frame, the other end and roller bearing
Other end connection；Upper ledge is connected with handle.
More preferably, the upper surface of lower frame is equipped with pin hole, and bolt is sequentially inserted into from top to bottom is arranged in upper ledge, the limit on roller bearing
Pin hole is inserted into position hole, and bolt insertion pin hole limits roller bearing, and restorer is inserted into surgical procedure and is carried out to roller bearing rotation
Limit, convenient for operation.
More preferably, roller bearing diameter becomes larger step by step from upper frame to lower frame, and every grade of diameter differs 1-2mm.
The invention has the advantages that slip vertebra carry out reseting procedure in by restorer be inserted into slip vertebra with it is adjacent solid
Determine between vertebra, during being lifted using pulling nail to slippage vertebra, slipping is force of rolling friction between vertebra and restorer roller bearing,
Its resistance is small, be conducive to slip vertebra smoothly reset, while restorer to two pleurocentrums damage it is small, will not influence Invasive lumbar fusion device with
Fusion.

Specific embodiment
Slippage vertebra restorer of the invention, including outline border 1 and roller bearing 2, outline border 1 include upper ledge 11, lower frame 12, left frame 13
With right frame 14, the both ends of left frame 13 are connect with the left end of upper ledge 11 and lower frame 12 respectively, the both ends of right frame 14 respectively with
Upper ledge 11 is connected with the right end of lower frame 12, and roller bearing 2 is arranged in parallel to be distributed in 1 frame of outline border and 2 diameter of roller bearing is greater than Thick
Degree, two sides are higher by outline border 1, and one end of the first connecting shaft 31 is connect with left frame 13, and the other end is connect with one end of roller bearing 2,
One end of second connecting shaft 32 is connect with right frame 14, and the other end is connect with the other end of roller bearing 2；Upper ledge 11 is connected with handle 4.
In surgical procedure, when being inserted into restorer, the rotation of roller bearing 2 is limited, bolt 5 can be used and be inserted into the pin of lower frame 12
15 mode of hole is equipped with pin hole 15 in the upper surface of lower frame 12, is provided with limit hole on upper ledge 11 and roller bearing 2, and bolt 5 is from upper
It is sequentially inserted under and upper ledge 11, the limit hole insertion pin hole 15 on roller bearing 2 is set, bolt 5 is inserted into pin hole 15, and bolt 5 is another
Upper ledge 11 is exposed at end, convenient for operation.
In the present embodiment, as shown in figure 3, roller bearing 2 is distributed using scale formula, 2 diameter of roller bearing is from 11 frame of upper ledge to lower frame 12
Frame becomes larger step by step, and every grade of diameter differs 1-2mm.Using the structure, in the case of the out-of-flatness of interbody bone face, be conducive to roller bearing 2 and bone
Face contact plays a role.
Fig. 4 illustrates a kind of use state of the present invention, and vertebral arch follows closely internal fixation system and includes lifting pedicle nail 202, fixes
Pedicle nail 201,203 and pitman 204 between the two, fixed pedicle nail 201,203 use one group or two groups, show in figure
Meaning uses two groups, is separately fixed at the upper centrum 101 for slipping vertebra 102 and the next centrum 103.In surgical procedure, it is first placed in vertebra
Nut nail, restorer are inserted from above into intervertenral space, are inserted into respectively between vertebra 102 and its adjacent two centrum 101,103 slipping
Restorer is slipping vertebra 102 and upper centrum 101, slip and be inserted into two restorers respectively between vertebra and the next centrum 103
(each one of left and right) after being implanted into restorer, installs pitman 204, and the roller bearing 2 of restorer is axial to hang down with slippage vertebra moving direction
Directly, bolt 5 is extracted from pin hole 15, bolt 5 is released and roller bearing 2 is limited, and under pulling nail upwards lifting effect, it is upward to slip vertebra
Mobile, slipping in the process is rolling friction between vertebra and roller bearing 2, and lifting resistance is small, is conducive to slippage vertebra and resets.
