In the present embodiment, the first elevating lever 4 and the second elevating lever 5 can also merge into one.But two elevating levers are to carrying
The overall stability of high device is reduced and is shaken with prominent effect.10 and second horizon bar 26 of first level bar can also close
And it is one.But for two horizon bars to the overall stability of raising device, reducing shaking etc. has prominent effect.
As shown in Figure 4,5, 6, guide-localization unit includes arc-shaped rail 22, guide rod 19, clamper 23, the second sliding block 17
And two position indicators, in the present embodiment, arc-shaped rail 22 is connected on the second sliding block 17, and the second sliding block 17 is connected to three-dimensional tune
On the first sliding block 24 for saving unit, and the second adjusting knob 14 is connected with, it is arc-shaped by the way that the second adjusting knob 14 is controlled to drive
Track 22 does the Arbitrary Rotation of 0-360 degree around vertical axes, can also in the range of 0-360 degree direct rotational circle curved track
To any angle, Fig. 4, Fig. 6 represent different conditions schematic diagram during the rotation of 22 and second sliding block 17 of arc-shaped rail in road.
Particularly, arc-shaped rail 22 can be moved around its center of circle relative to the second sliding block 17, and Fig. 4, Fig. 5 represent arc-shaped
22 and second sliding block 17 of track is in different location relation condition.Arc-shaped rail 22 can also be connected with the first hook knob
16, when arc-shaped rail 22 is moved to suitable position relative to the second sliding block 17, can be locked by the first hook knob 16
The position of arc-shaped rail.In actual operation operating process, this structure or this relative movement can hinder to avoid patient body
Arc-shaped rail is kept off to rotate around vertical axes, it is extremely important for adjusting operative approach angle, expansion surgical operation space,
With prominent substantial effect.
The Technology design that arc-shaped rail can move on the second sliding block, substantial effect and prominent meaning specifically exist
In following 2 points (such as Figure 12,13)：
1st, the foramen intervertebrale lens operation of normal prone position is lateral approach to the rear, only need to revolve arc-shaped rail around vertical axes
Turn that ideal operating path can be obtained, however, when the operation of other Posterior approachs is carried out using the positioning device, such as vertebra
Pedicle screw merging etc., due to the blocking of body, if arc-shaped rail can only surround vertical axes rotation and can not obtain preferably
Operating path, thus must by arc-shaped rail around the center of circle move in a circle i.e. relative to the second sliding block move after again by circular arc
Shape track is rotated around vertical axes, can obtain ideal operating path.Therefore, arc-shaped rail moves in a circle around the center of circle
With great clinical meaning, there is prominent substantial effect.
2nd, merge the patient of the bad protrusion of lumber intervertebral disc of cardio-pulmonary function for part, clinically often take lateral position into
Row foramen intervertebrale lens are performed the operation, and ideal operating path can not be also obtained as arc-shaped rail can only surround vertical axes rotation.It is intended to reach
Ideal operating path puncture and other operations, it is necessary to which arc-shaped rail moves in a circle i.e. around the center of circle relative to the
Two sliding blocks movement back wall is rotated around vertical axes, and therefore, arc-shaped rail moves in a circle around the center of circle solves clinical reality
Problem has prominent substantial effect.
Arc-shaped rail 22 is connected to by the second sliding block 17 on the first sliding block 24, can be by lift adjustment unit and level
Adjusting unit drive lifts, left-right and front-back movement.
