Preferably, the connection block 27 on one side of the first semi-annular needle base 4, the second hole 14 on the top of the connection block 27, the first plate semi-arc plate 16 tightly welded on one side of the connection block 27, the second semi-arc plate 17 at the bottom of the first plate semi-arc plate 16 and the second bolt 26 on the other side of the connection block 27 jointly form a needle base adjusting and fixing mechanism, because in the existing device, the flexibility of the device is poor, the fracture parts of different patients are different, the angle of the needed fixed contact pin is also different, by arranging the adjusting and fixing mechanism, the connection block 27 is arranged on one side of the first semi-annular needle base 4, the second hole 14 is arranged on the surface of the connection block 27, the guide rod can penetrate through the second hole 14, the first semi-annular needle base 4 can be moved up and down on the guide rod by manually moving, meanwhile, the second bolt 26 is arranged on one side of the connection block 27, the first semi-annular needle base 4 after moving can be fixed, meanwhile, a first plate semi-arc plate 16 is arranged on the device, a needle seat sliding groove 18 is formed between the first plate semi-arc plate 16 and a second semi-arc plate 17, and a needle holder 21 can conveniently penetrate and fix on the needle seat sliding groove 18, so that the adjustable controllability of the adjusting and fixing mechanism is well embodied.

Preferably, the fixed rod 7 at the bottom of the first guide rod 1, the connecting sleeve 10 at the top of the fixed rod 7, the sliding groove 22 inside the connecting sleeve 10, the telescopic rod 3 at the top of the connecting sleeve 10 and the first bolt 8 at one side of the connecting sleeve 10 together form an extension adjusting mechanism, because the prior device has simple structure, poor flexibility and large structure and is inconvenient to store, by providing an extension adjustment mechanism, the user can adjust the extension of the first screw 8, by rotating the first screw, so that the connection sleeve 10 is loosened, and the telescopic rod 3 is manually stretched, so that the telescopic rod 3 moves in the sliding groove 22 inside the connecting sleeve 10, make first guide arm 1 elongate or shorten, make things convenient for medical personnel to adjust according to actual conditions, the adjusting device overall size of being convenient for conveniently deposits or adjusts to fine embodiment this fracture restorer device's adjustable suitability.

The working principle is as follows: firstly, the clamping block 23 is arranged at the top of the needle holder 21, the clamping block 23 is provided with a convex clamping plate which can be clamped in the clamping groove 28, so that the needle holder 21 is fixed in the fixing nut 20, the needle holder 21 is prevented from shaking due to adjustment of the penetrating position, and the detail of the device is well embodied;

then, by arranging the needle seat sliding groove 18 and arranging the needle seat sliding groove 18 on the surface of the first semi-arc needle seat 4, the needle holder 21 can move along the arc of the needle seat sliding groove 18, so that the adjustment and fixation of various positions are facilitated, and the resetting is more flexible;

then, by arranging the limb fixing mechanism, a sliding groove 13 is arranged on one side of the surface of the first semi-ring fixing plate 6, the sliding groove 13 can penetrate into the second guide rod 2, meanwhile, the second guide rod 2 is fixed on the first semi-ring fixing plate 6 through a fixing nut 5, the second guide rod 2 can slide in the sliding groove 13, the position between the two guide rods can be conveniently adjusted, the size can be conveniently adjusted to be suitable, the limb is fixed more firmly, and the adjusted guide rod is fixed by rotating the fixing nut 5, so that the fixing firmness of the fracture repositor device is well embodied;

next, by arranging the adjusting and fixing mechanism, one side of the first semi-annular needle seat 4 is provided with the connecting block 27, the surface of the connecting block 27 is provided with the second hole 14, the second hole 14 can enable a guide rod to penetrate, the first semi-annular needle seat 4 can be moved up and down on the guide rod by manually moving, meanwhile, one side of the connecting block 27 is provided with the second bolt 26, the first semi-annular needle seat 4 after moving can be fixed by the second bolt 26 in a rotating mode, meanwhile, the device is provided with the first plate semi-arc plate 16, the needle seat sliding groove 18 is formed between the first plate semi-arc plate 16 and the second semi-arc plate 17, the needle clamping device 21 can conveniently penetrate and fix on the needle seat sliding groove 18, and therefore, the adjusting and fixing mechanism can be adjusted and controlled well;

finally, through setting up the extension adjustment mechanism, the rotatory first bolt 8 of user's accessible, make adapter sleeve 10 relax, and manual tensile telescopic link 3, make telescopic link 3 remove at the inside sliding tray 22 of adapter sleeve 10, make first guide arm 1 elongate or shorten, make things convenient for medical personnel to adjust according to actual conditions, the adjusting device overall size of being convenient for, conveniently deposit or adjust, thereby fine embodiment the adjustable suitability of this fracture restorer device, this is exactly this kind of adjustable fracture restorer's theory of operation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
