As shown in fig. 1, fig. 3, fig. 4 and fig. 5, interior sleeve pipe 2 is threaded connection in clockwise and anticlockwise screw rod 3 and its both ends, and its both are connected the whole of formation and are fixed on outer tube 1 through first screw 4, the end of interior sleeve pipe 2 in both ends all is provided with sleeve pipe recess 5, and the link block of connecting plate 6 is in sleeve pipe recess 5, fix through the screw, this partial complete connection forms telescopic tube's structure, under telescopic tube's effect, can adjust whole telescopic tube's length through rotatory clockwise and anticlockwise screw rod 3, and then make things convenient for the later stage to carry out the operation demand of the action that resets of fracture.

As shown in fig. 1, the independent single side lug 7 that is provided with in the left and right sides of connecting plate 6, and swivel mount 8 is fixed directly over connecting plate 6, the bottom surface of its swivel mount 8 passes through the screw hole just right to with connecting plate 6 and passes through second screw 9 connection fixed, be provided with the screw hole on the side lug 7, and promote screw 10 and run through wherein, promote a side of contact swivel mount 8, this partial complete connection forms the structure of adjusting the head, it dies to promote the fixed lock that screw 10 can control swivel mount 8, make swivel mount 8 can not random activity, and then probably influence the effect that the fracture resets.

As shown in fig. 2, 8-11, the three-nail fixing plate 11 is disposed between two side edges of the rotating frame 8, and the two side edges pass through correspondingly disposed screw holes, the three-nail fixing plate 11 and the rotating frame 8 form a rotating whole through the fixing screws 14 by penetrating the fixing screws 14 through the screw holes for movable connection, the three-nail fixing plate 11 can rotate by taking the fixing screw 14 as a rotating shaft by adjusting the adjusting screw 13 penetrating through the three-nail fixing plate 11, the pressing plate 12 is pressed right above the three-nail fixing plate 11, three parallel nail grooves 1101 are arranged on the surface of the three-nail fixing plate 11, two screw holes are arranged on the three parallel nail grooves 1101 on the three-nail fixing plate 11, and the surface facing to the pressing plate 12 is also provided with three groups of two screw holes, the upper surfaces of the three-nail fixing plate 11 and the pressing plate 12 are correspondingly provided with two vertical holes, and the adjusting screw 13 penetrates through the three-nail fixing plate 11 and the pressing plate 12 to be adjusted and connected.

The working principle is as follows: referring to fig. 1-15, the telescopic tube composed of the outer tube 1, the inner tubes 2 at two ends and the clockwise and counterclockwise screws 3, the adjusting head composed of the connecting plate 6, the rotating frame 8, the three-pin fixing plate 11 and the pressing plate 12:

a) the bone round nails are completely used, the straight threads of 3.5 mm and 4 mm can be used together, and threaded nails are not used, because the threaded nails can reduce the strength of the nails and allow a small amount of non-parallelism of the nails, and certainly, the nails with successfully screwed heads can also be used;

b) the limbs are placed in the correct rotation position and slightly pulled and then nailed;

c) the nail feeding point is marked by a color pen, the skin is pulled to the fracture part, and the nail feeding is vertical to the backbone;

d) before entering the bone round nail, a flat drill bit is used for drilling a through hole smaller than the bone round nail, the flat drill bit is easier to insert than a spiral drill bit, and the tissue damage is small;

e) drilling a bone round nail into opposite cortex by a drilling tool through a pre-drilling hole, driving the nail into the opposite cortex without a mallet as much as possible so as to avoid bone fracture, and then connecting and fixing the bone round nail and the pressing plate 12;

f) the pressing plate 12 is firmly fixed on the three-nail fixing plate 11 by using the hexagon socket head cap screws, the nails cannot be completely parallel, and cannot easily slide out after being pressed, at least one nail is required to be in the nail groove 1101, other nails cannot be in the nail groove 1101, and the joint fracture is approached; then, the adjusting screw 13 is rotated to drive the three-nail fixing plate 11 to rotate so as to carry out certain traction on the fracture part, and meanwhile, the inner sleeve 2 can be rotated on the clockwise and anticlockwise screw rods 3 by rotating the inner sleeve 2 so as to carry out traction reduction on the fracture part;

the bone bolar has the properties, so that the flexible sleeve is required to relax and draw after fracture resetting, a fracture gap is prevented from being caused by the linear drawing of the bone bolar but cannot be compressed, the fracture can be dislocated due to compression, and after two weeks, the X sheet is shot to check the fracture resetting condition and the appearance or displacement of the fracture without a gap;

g) after the fracture is reset, the upper and lower joints of the fracture are not fixed any more, in order to increase the fixing strength, local plaster tube fixing is carried out, femoral fracture is fixed from the thigh root to the lower part of the knee joint, the knee joint part is kept moving, tibiofibular fracture is fixed by a short leg plaster tube, the head part of the fracture is regulated to be cut off, so as to be prepared for cleaning and disinfection of the nail meatus after operation and regulation and correction when possible fracture displacement, plaster is completely split to prevent the blood flow from being blocked, the plaster is generally removed for 4 weeks and 6 weeks, the fracture of the upper limb is not fixed by plaster, but is strengthened and fixed by a small splint, and the femoral tuberosity;

h) the overlong part of the nail is cut off so as not to influence life;

i) for closed fracture patients, the operation can be completed by using the internal anesthesia of hematoma;

j) the telescopic sleeve and the adjusting head have various models, can be compatible and can be adjusted mutually according to requirements.

To thereby carry out a series of tasks, the contents of which are not described in detail in the present specification are prior art well known to those skilled in the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
