Specific embodiment
The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to
In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model
Protection scope, the pause mark in the utility model indicates the relationship of sum.
As Figure 1-Figure 4, a kind of tail bone intervertebral disc degeneration experimental provision provided by the utility model first embodiment,
It is characterized by comprising each tail bone sleeve 1,2 of draw-bar seat 5 and left and right, two tail bone sleeves 1,2 are left and right perforation
Column-shaped barrel, the lower part of left tail bone sleeve 1 are fixed with guide pin cylinder 3, and the lower part of right tail bone sleeve 2 is fixed with guide pin bar 4;
The guide pin cylinder 3 be up and down be vertically arranged straight tube, the barrel lower part of left tail bone sleeve 1 offers pin holes, should
Pin holes are docked with the upper end nozzle of guide pin cylinder 3;
Contact pin guide hole 21 is offered on the barrel of the right tail bone sleeve 2, which is along right tail bone sleeve
The circumferential line segment shape through-hole extended from bottom to top offers the multiple contact pin bayonets being recessed to the right on the hole wall of contact pin guide hole 21
22, and each contact pin bayonet 22 is sequentially spaced apart from bottom to top;
The guide pin bar 4 is to be vertically arranged straight-bar, and straight trough 41 up and down, the straight trough are offered on the outer surface of guide pin bar 4
It is docked with the lower end of contact pin guide hole 21 41 upper end;
Each pull rod 6 around is hinged on the draw-bar seat 5, the left end of left lever 6 and guide pin cylinder 3 are hinged, right pull rod 6
Right end and guide pin bar 4 it is hinged, the multiple location holes 61 being spaced apart all are offered on every pull rod 6 from left to right.
The utility model first embodiment can utilize abnormal distortion, the gryposis of rat tail bone simulation people's backbone, simulation
The method of experiment is as follows:
Rat tail bone is penetrated into two tail bone sleeves, three segment rat-tail vertebras is spaced between two tail bone sleeves, makes three
The rat-tail vertebra of segment can be bent, and a Kirschner wire 7 is then inserted into left tail bone sleeve by guide pin cylinder, will be in left tail bone sleeve
Rat tail bone is fixed, and another Kirschner wire 7 is inserted into right tail bone sleeve by the guiding of the straight trough 41 of guide pin rod outer surface, and
So that the Kirschner wire is inserted into the rat tail bone (as shown in Figure 1) in right tail bone sleeve;
When needing to simulate people's backbone exception distortion, right side Kirschner wire is moved along contact pin guide hole, right side gram can be passed through
Family name's needle drives the right part of rat tail bone, at this time since the left part of rat tail bone is lived by left side Kirschner wire fixation, so that two tail bones
Rat-tail vertebra between sleeve generates twisted state shown in Fig. 3, after right side Kirschner wire is moved at contact pin bayonet 22, can block to the right
Enter in contact pin bayonet 22, so as to make the rat-tail vertebra between two tail bone sleeves be maintained at twisted state;
