Specific embodiment
Hereinafter, be described further with attached drawing for the utility model in conjunction with the embodiments, embodiment and attached drawing are only used for solving
It releases explanation rather than limits the protection scope of the utility model.
" curved outside " and " curved interior " as described in the examples are described to be referred to when bending, the folding of waist buttocks
The folded biggish side of angle is curved interior, and the lesser side of angle is curved outside, and left side is curved outside in Fig. 1, right
Side is curved interior, which is relative position rather than absolute position.
More piece as described in the examples simulates lumbar vertebrae, the simulation lumbar vertebrae including L1 ~ L5.
Can adjust automatically lumbar puncture manikin as shown in Figure 1, including manikin, the manikin includes
The upper body on top, the waist buttocks at middle part, lower part lower part of the body portion, wherein waist buttocks has flexibility, the upper body, waist buttocks
It can be independent structure as shown in figure 1 with lower part of the body portion to connect to be formed by pivot pin, be such as also possible to integral structure, lower part of the body portion again may be used
It is divided into huckle and calf, huckle is connected with calf by pivot pin.Its mode connected is provided to so that and human body
Shape is more bonded.
Lower part of the body portion connects a walking mechanism, and walking mechanism drives the movement of lower part of the body portion so that manikin is stretched in waist hip point
Exhibition is bent, and has fulcrum in the curved interior of the upper body, after the bending is carried out in manikin, lower part of the body portion
The surface of curved interior leans against on the fulcrum, forms the report knee organization of human body of Fig. 3.The walking mechanism includes Guiding machine
