Specific embodiment
Referring to Fig. 1, the present invention include rack 25 and the correction mechanism up and down being mounted in rack 25, left and right correction mechanism,
Auxiliary reset device and traction resetting device, wherein the lower part of rack 25 is equipped with universal wheel 18, and upper and lower correction mechanism includes level
Sliding rail 11 and multiple correcting units up and down, each correcting unit up and down includes sliding block 14, slider locking screw 13, lift actuator
15, vertical pull rod 16 and cross bar 12, left and right correction mechanism include horizontal slide 19 and multiple left and right correcting units, and each left and right is rectified
Positive unit includes slide 23, sliding seat locking screw 24, traversing driver 22, girt 21 and upright bar 20；Each 12 He of cross bar
Upright bar 20 is equipped with arc panel 26.Auxiliary reset device include three universal joints 1 of bulb, lower swing arm 2, upper swing arm 3, regulating arm 6,
Clamping screw 7 and Kirschner wire 8；Traction resetting device includes that handwheel 4, screw 5, lead screw 9, mobile U-shaped hitch frame 10 and fixation are U-shaped
Hitch frame 17.
Upper and lower correction mechanism and left and right correction mechanism are the device for applying lateral thrust to knochenbruch, the basic phase of the two structure
Together, only installation direction is different, and upper and lower correction mechanism is used to apply knochenbruch downward pressure or upward lifting force, and left and right is rectified
Positive mechanism is used to apply knochenbruch the thrust of left and right directions, and upper and lower correction mechanism and left and right correction mechanism simultaneously exert a force to knochenbruch,
The fracture of bone can be made to coincide, pulp cavity alignment.
Correcting unit can both apply downward pressure to each of upper and lower correction mechanism to knochenbruch up and down, can also be to knochenbruch
Apply upward lifting force, when needing to apply downward pressure, cross bar 12 and arc panel are placed in the top of knochenbruch, cross bar 12
The through-hole on vertical 16 top of pull rod is inserted into one end, and lift actuator 15 pushes cross bar 12 and arc panel downward by vertical pull rod 16
It is mobile；When needing to apply upward lifting force, cross bar 12 and arc panel are placed in the lower section of knochenbruch, one end insertion of cross bar 12 is perpendicular
The through-hole of 16 lower part of Drag link, lift actuator 15 pull cross bar 12 and arc panel to move up by vertical pull rod 16.
Similarly, each left and right correcting unit of left and right correction mechanism both can apply thrust to the left to knochenbruch, can also be with
Thrust to the right is applied to knochenbruch.When needing to apply thrust to the left, upright bar 20 and arc panel are placed in the right side of knochenbruch, upright bar
The through-hole on 20 21 right side of one end insertion girt, traversing driver 22 drive upright bar 20 and arc panel by girt 21
It is moved to the left；When needing to apply thrust to the right, upright bar 20 and arc panel are placed in the left side of knochenbruch, one end insertion of upright bar 20
The through-hole in 21 left side of girt, traversing driver 22 drive upright bar 20 and arc panel to move right by girt 21.
It will be seen from figure 1 that in the position adjustment of left and right correcting unit and upper and lower correcting unit, upright bar 20 and cross
Bar 12 is likely to occur interference, it is therefore necessary to after waiting left and right correcting unit and upper and lower correcting unit to be adjusted in place, then install upright bar
20 and cross bar 12.
Referring to Fig. 2 and Fig. 3, lift actuator 15 is identical with the structure of traversing driver 22, be all by shell 15-1,
What linear guide 15-2, rack gear 15-3, turning handle 15-4, driving gear 15-5, pinion gear 15-6 and gear wheel 15-7 were constituted, only
Installation direction is different, and the rack gear 15-3 of lift actuator 15 is vertically-mounted, and the rack gear 15-3 of traversing driver 22 is water
Safety dress.Driving gear 15-5, pinion gear 15-6 and gear wheel 15-7 constitute double reduction mechanism, by rotating turning handle 15-4
Rack gear 15-3 can be made to move along linear guide 15-2, position degree of regulation not only can be improved in deceleration mechanism, but also has self-positioning
Function not will drive each gear rotation when rack gear 15-3 is by external thrust.
Auxiliary reset device is used to carry out auxiliary positioning to knochenbruch, and three ball head universals 1 make lower swing arm 2,3 and of upper swing arm
Regulating arm 6 can flexible rotating, and can fix in place.When needing that bone is fixed, first by 6 turns of regulating arm
Suitable position is moved, three ball head universals 1 are locked, after a then pin hole 6-1 that Kirschner wire 8 is passed through to regulating arm 6
Knochenbruch is penetrated, is finally locked Kirschner wire 8 with clamping screw 7, knochenbruch can be fixed.
Referring to Fig. 4, regulating arm 6 is equipped with the multiple and matched pin hole 6-1 of Kirschner wire 8, and multiple pin hole 6-1 are along regulating arm 6
Equal spacing in length direction arrangement, this structure makes the fixation of Kirschner wire 8 more convenient.
The present apparatus can be used cooperatively with traction table, carry out three-dimensional space reset to knochenbruch.Traction resetting device, which has, to be led
The function of drawing bed, in the case where lacking traction table, the present apparatus equally can guarantee going on smoothly for operation.
The present apparatus is multiple functional, easy to operate, reliable for operation, can effectively improve surgical quality, be it is a kind of have answer extensively
With the bone surgery set of value, it is suitable for promoting and applying in various orthopaedics medical treatments.
