Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings：
Fig. 1 is dimensional structure diagram of the present utility model；
Fig. 2 is Fig. 1 opposite side dimensional structure diagram.
Fig. 3 is Fig. 1 side structure schematic view.
Embodiment
With reference to embodiment, the utility model is expanded on further.
As shown in Figure 1, 2, 3：A kind of paediatrics waist wears the safe guiding device in direction, including is provided with the positioning in guiding puncture hole 3
Block 2, the both sides of locating piece 2 are provided with two support bars 1 of coaxial line, are provided with and can be slid axially along it on each support bar 1
Positioning sliding block 5, the bottom surface of the locating piece 2 is higher than the bottom surface line certain distance of the positioning sliding block 5, the positioning sliding block
5 leading edge line exceeds the leading edge certain distance of locating piece 2, and the bottom of the locating piece 2 is provided with positioning groove 4, and positioning is logical
The axis perpendicular of the axis of groove 4 and the support bar 1, the axis in the guiding puncture hole 3 are logical both perpendicular to the positioning
The axis of the axis of groove 4 and the support bar 1.The positioning groove 4 set by the bottom of locating piece 2, blocks phase on patient's vertebra
Adjacent spinous process, provides horizontal location for point of puncture, the both sides ilium of patient is propped up by the positioning sliding block 5 on two groups of support bars 1
