Detailed description of the invention
This utility model is made up of drawing pull bar 1, fixing bar 4, fixed chuck 8, Kirschner wire 12, and drawing pull bar 1 is stock, and fixing bar 4 and fixed chuck 8 have two groups respectively.
Figure shows, drawing pull bar 1 is made up of two pull bars and screw sheel 2, the inwall of screw sheel 2 there is screw thread, one end of two pull bars has the screw thread of screw thread and screw sheel 2 inwall to match respectively, threadeding with screw sheel 2 respectively in one end of two pull bars, the other end of two pull bars has connecting hole 3 respectively.The length of drawing pull bar 1 can be regulated by the connecting length of rotating screw sleeve 2 and two ends pull bar, make fracture site 13 move to two ends, the overlapping displacement of fracture site 12 can be corrected.
The thread rotary orientation at the inwall two ends of screw sheel 2 is contrary, and the screw thread of one end of two pull bars matches with the screw thread at screw sheel 2 inwall two ends respectively, and when rotating screw sleeve 2, two pull bars can be strained simultaneously or unclamp, it is simple to carry out tractive.
Showing in figure, screw thread is arranged at the top of two fixing bars 4, and the upper end of fixing bar 4, through the connecting hole 3 at drawing pull bar 1 two ends, is rotary with locknut 5 respectively on the fixing bar 4 of connecting hole 3 both sides, and the connecting hole 3 of fixing bar 4 with pull bar is locked by locknut 5.Connecting hole 3 can be circular hole, it is also possible at outboard end opening, circular hole is connected firmly after locknut 5 is tightened, and open-ended connection is convenient.
Figure shows, the lower end of two fixing bars 4 respectively semicircular arc groove 6, the top of fixed chuck 8 is spheroid 9, the spheroid 9 on fixed chuck 8 top is embedded in the semicircular arc groove 6 of fixing bar 4 lower end, the sidewall of semicircular arc groove 6 there is top wire hole, jackscrew 7 holds out against fixing through the spheroid 9 on top wire hole and fixed chuck 8 top, rotates spheroid 9 and can realize universal connection, by rotate fixed chuck 8 correct fracture site 13 rotation displacement.
Figure shows, the bottom of two fixed chucks 8 lays respectively at bone fixed position 14 place at fracture site 13 two ends, the bottom of two fixed chucks 8 semicircular arc clamping plate 10 that oriented both sides are stretched out respectively, two semicircular arc clamping plate 10 lay respectively at the both sides of bone fixed position 14, there is fixing hole 11 two semicircular arc clamping plate 10 lower ends relatively respectively, and Kirschner wire 12 is connected through fixing hole 11 is fixing with bone fixed position 14.
Work process of the present utility model is as follows:
First, the semicircular arc clamping plate 10 of fixed chuck 8 lower end are placed on the both sides of bone fixed position 14, are connected with the fixing hole 11 of Kirschner wire 12 traverse semicircular arc clamping plate 10 is fixing with bone fixed position 14；
, the two of drawing pull bar 1 pull bars are connected with screw sheel 2 meanwhile, more fixing bar 4 upper end is connected by the two ends of connecting hole 3 with drawing pull bar 1, and fix with locknut 5.
Then, the connecting length of rotating screw sleeve 2 and two ends pull bar can regulate the length of drawing pull bar 1, makes fracture site 13 move to two ends, can correct the overlapping displacement of fracture site 12.
The spheroid 9 on fixed chuck 8 top is placed in the semicircular arc groove 6 of fixing bar 4 lower end, rotate fixed chuck 8 correct fracture site rotation displacement, spheroid 9 is held out against fixing with jackscrew 7 through top wire hole after being rotated in place.
Can realize resetting and fixing carrying out simultaneously, reach at once stable effect.
