Be provided with the positioning tooth of continuous distribution in the middle of the end face of the said propelling push rod of this utility model along its length, on the box body support location-plate is installed, location-plate is provided with the pressing plate and the locating detent of one, it is installed on the box body support by bearing pin and spring, pressing plate is positioned at box body support rear portion, it is set on the propelling push rod that stretches out from box body support rear portion, and locating detent stretches into box body support intracavity, cooperates with positioning tooth.
Also be provided with a central through hole on the said propelling push rod of this utility model length direction.
This utility model trigger-type presses pendulum to be installed in box body support below by bearing pin and spring, and its upper end is connected with elastic card claw, and is positioned at box body support intracavity, with ratchet engagement, pull press pendulum, elastic card claw promote to advance push rod along sleeve to front slide.
The said ratchet of this utility model is a right angle zigzag ratchet.
This utility model fracture reposition instrument is a gun type of gas burner, hold the trigger action formula and press pendulum, the promotion that elastic card claw on it drives the upper end advances push rod to move forward along sleeve, cooperate with the arc button gripping arm that advances push rod the place ahead, clamp fracture site to be positioned, that reset, then squeeze into positioning needle to bone fracture place by the central through hole that advances push rod.Against existing technologies, it is simple in structure, use easy to operately, utilize to advance the principle of pressurization that fracture, bone fracture location are resetted gradually, resetting, it is accurate to balance in power, it is reliable to reset, be difficult for becoming flexible, can reduce intraoperative hemorrhage, also reduced the chance of tractive dura mater injured nerve, alleviated patient's misery, clinical trial result is good.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
1. arc button gripping arms among the figure 2. advance push rod, 21. ratchets, and 22. positioning tooths, 23. central through holes, 3. sleeve, 4. box body support, 5. elastic card claw, 6. bearing pin, 7. trigger-type is pressed pendulum, 8. spring, 9. handle, 10. locating detent, 11. bearing pins, 12. springs, 13. pressing plates.
The specific embodiment
As can be seen from Figure 1, a kind of fracture reposition instrument, it comprises rifle formula main body, arc button gripping arm 1, advances push rod 2 etc.Rifle formula main body is provided with box body support 4, sleeve 3, is connected the handle 9 of box body support 4 belows, trigger-type is pressed pendulum 7 etc.Sleeve 3 is fixedly mounted in the box body support 4 and extends forward, advances push rod 2 to run through and is installed in the sleeve 3.Arc button gripping arm 1 is fixedly mounted on the box body support 4, and it is bow-shaped structural, and the button of front end is held the top and is positioned at and advances push rod 2 the place aheads, and advances push rod 2 on same axis.Arc button gripping arm 1 withstands on the fracture site along propelling push rod 2 progressive opposite directions, cooperates with propelling push rod 2 to clamp fracture site.
This utility model advances the middle ratchet 21 that is provided with continuous distribution along its length in push rod 2 bottom surfaces, and said ratchet 21 is a right angle zigzag ratchet.Ratchet 21 presses pendulum 7 elastic card claws that are provided with 5 to cooperate with trigger-type, and advancing push rod 2 to press at trigger-type can only be to front slide in sleeve 3 under pendulum 7 effects.Trigger-type presses pendulum 7 to be installed in box body support 4 belows by bearing pin 6 and spring 8, and its upper end is connected with elastic card claw 5, and is positioned at box body support intracavity, cooperates with ratchet 21.Pull trigger-type backward and press pendulum 7, elastic card claw 5 and ratchet 21 the two engagement advance push rod 2 pressing under the pendulum thrust and can only move forward along sleeve, move closer to arc button gripping arm 1 top, clamp fracture site, and be to advance pressurization gradually, fracture, bone fracture location are resetted; Unclamp trigger-type and press pendulum 7, under spring 8 effects, the two gets loose elastic card claw 5 and ratchet 21, advances push rod 2 to be free to slide or to adjust the position under the effect of positioning tooth 22 and location-plate along sleeve 3.
