Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is described further:

Fig. 1 is structural representation of the present invention;

In figure: 1, rubber drift, 2, stud, 3, hollow bolt, 4, stroke body, 5, push rod, 6, pulling plug, 7, cavity, 8, push rod, 9, unidirectional restriction draw-in groove, 10, chute, 11, spring, 12, handle, 13, trigger, the 14, first articulated stand, 15, groove, 16, striker, 17, garter spring, 18, ratchet, 19, determine frequency modulator, 20, dividing plate, 21 second articulated stands.

The specific embodiment

As shown in Figure 1, a kind of prolapse of lumbar intervertebral disc positor, comprises main body, drive mechanism and the mechanism that has an effect.

Described main body comprises handle 12 and cavity 7, and handle 12 is arranged on cavity 7.The column type that cavity 7 is hollow, an end opening, its opening is provided with external screw thread, is provided with vertically chute 10 on the sidewall of cavity 7.

The described structure of having an effect comprises spring 11, pulling plug 6, push rod 8, trigger 13 and determines frequency modulator 19.Spring 11 and push rod 8 are positioned at the inside of cavity 7; One end of spring 11 is connected on the rear end face of cavity 7 inside, and the other end is connected to push rod 8 rear ends; The front end of push rod 8 is provided with striker 16; Pulling plug 6 one end are fixed on push rod 8, and the other end stretches out from the chute 10 of cavity 7; The bottom of push rod 8 is provided with three unidirectional restriction draw-in grooves 9 along axis direction; Trigger 13 is fixed on handle 12 by the first articulated stand 14, and trigger 13 can rotate at the pin joint place on the first articulated stand 14.

Determine frequency modulator 19 and in one end of the second articulated stand 21, be provided with groove 15 and ratchet 18, the centre position of determining frequency modulator 19 is fixed on cavity 7 by the second articulated stand 21, determines frequency modulator 19 and can rotate at the pin joint place on the second articulated stand 21; Determine to be provided with garter spring 17 between the other end of frequency modulator 19 and cavity 7.

One end of trigger 13 is stuck in the groove 15 of determining frequency modulator 19, and the ratchet 18 of determining on frequency modulator 19 inserts and be pushed against the bottom of push rod 8 from the through hole of cavity 7 bottoms, and ratchet 18 forms unidirectional limiting mechanism with the unidirectional restriction draw-in groove 9 on push rod 8.When pulling back pulling plug 6, ratchet 18 sticks into three interior three unidirectional restriction draw-in grooves 9 of unidirectional restriction draw-in groove 9 successively by being followed successively by a gear, two gears, three gears before backward, and wherein the impulsive force of a gear is minimum, and the impulsive force of three gears is maximum.Described garter spring 17 can drive determines frequency modulator 19 around the rotation of the pin joint place of the second articulated stand 21 so that ratchet 18 snaps in unidirectional restriction draw-in groove 9 and can not deviate from easily.

Described drive mechanism comprises stroke body 4, stud 2, push rod 5 and hollow bolt 3.The cylinder that described stroke body 4 is hollow, both ends open and two ends are equipped with female thread, and the rear end of stroke body 4 is threaded connection the front end of cavity 7, and the front end of stroke sleeve 4 is threaded connection hollow bolt 3.In the inner chamber of stroke sleeve 4, be radially provided with dividing plate 20, dividing plate 20 center is provided with through hole, and through-hole diameter is greater than the diameter of striker 16.Described push rod 5 is in the inside of stroke body 4 and between dividing plate 20 and hollow bolt 3.Described stud 2 one end extend into the inside of stroke body 4 through hollow bolt 3, and are connected with the front end of push rod 5 by screw thread, and the other end of stud 2 is connected with rubber drift 1 by screw thread.The internal diameter of described hollow bolt 3 is less than the external diameter of push rod 5, can play restriction to the travel distance of stud 2, prevents that stud 2 and rubber drift 1 from coming off.

During use, first pull back pulling plug 6, pulling plug 6 drives push rod 8 to move backward, and push rod 8 Compress Springs 11, can select suitable gear as required, unclamp pulling plug 6, and ratchet 18 snaps in the unidirectional restriction draw-in groove 9 of corresponding gear.

Then rubber drift 1 is against to outstanding intervertebral disc position, cocking 13, trigger 13 is stirred and is determined frequency modulator 19 and rotate counterclockwise around the pin joint place of the second articulated stand 21, the ratchet 18 of determining on frequency modulator 19 moves down from unidirectional restriction draw-in groove 9, now push rod 8 travels forward rapidly under the elastic force effect of spring 11, the striker 16 of its head strikes on push rod 5 through the through hole on dividing plate 20, then push rod 5 passes to rubber drift 1 by stud 2 by impulsive force, and the impulsive force that rubber drift 1 produces a moment makes outstanding intervertebral disc position passive reset.
