Insert in the screw hole with holes on month shape plate with holes with the intermediate thread pin, most advanced and sophisticated under the tibia 1/3 fracture near-end pass, with intermediate thread partial fixing bone stump, the tip is inserted in the offside screw hole with holes, the twisting hex nut moves up casing clamp, blocks the intermediate thread pin; With above-mentioned same quadrat method of threading a needle from big leg outer side, in the groove between the two draw point clamping plate in connecting clamping plate, be screwed into stage casing free bone folded block with one piece of spiral shell pin and one piece of intermediate thread pin, the intermediate thread pin passes sclerite, and tip portion places between offside trough of belt lower plate and the trough of belt train wheel bridge in the groove; The fixing fibula broken ends of fractured bone at last, hole at fracture site, with the fixing fibula of two ends screw needle, two ends screw needle afterbody and groove shape plate coupling nut are fixed, begin each fracture site of reduction then, the fixedly spiral shell pin screwed pipe that resets on hand connects in spiral shell pin and intermediate thread pin, reset the hands front end gusset piece the hole with connect fixture block, the train wheel bridge one side screw that connects on the clamping plate connects, screw is fixed, and tightens the fixing spiral shell pin of screw on the fixing spiral shell pin screwed pipe, according to X-ray film, the capstan nut on the hands concavity fixed block of resetting turns clockwise, fixedly spiral shell pin screwed pipe and spiral shell pin move forward together, inhour rotation capstan nut, and fixedly spiral shell pin screwed pipe and spiral shell pin move backward, correct a femur and a fracture of tibia broken ends of fractured bone left side, tighten capstan nut behind the dextroposition, take off the hands that resets after the spiral shell pin is fixed between the clamping draw point clamping plate; The scale that resets on hand can demonstrate spiral shell pin displacement; Twisting connects the capstan nut on two screw rods of clamping plate, makes it at the groove screw rod and long open slot screw rod is upper and lower moves, and makes fixedly that the spiral shell pin of fracture site moves along with upper and lower, is shifted to correct the bone stump front and back; 1/3 fracture far-end shifts forward on the rectification femur, restoring board perforated plate in right angle connected with fixation clamp be screwed, clockwise direction rotates eye bolt on another panel, the eye bolt front end promotes short open slot screw rod moves down connection fixture block bone fixation broken ends of fractured bone spiral shell pin together, shift forward in order to correct the Fracture of femur broken ends of fractured bone, correct 1/3 nonunion on the femur, if nearly folding end is to retrodisplacement, the Bolt Connection of the groove on the right angle restoring board in the fixture block that is fixedly connected, fix with capstan nut, clockwise direction turns eye bolt, the side plate and the fixed fracture site of spiral shell pin that make the eye bolt front end promote fixation clamp move forward thereupon, to correct fracture site to retrodisplacement, the centre screw rod with holes of twisting coupling bar, the short open slot screw rod of twisting, long open slot screw rod, press capstan nut on the link rod with meter on the groove screw rod, make to connect clamping plate and connect between the fixture block spiral shell pin distance and dwindle, produce the bone stump plus-pressure; And on the scale on the meter pressure pipe, demonstrate pressure, if the overlapping displacement of bone stump can twist capstan nut and make bone stump both sides spiral shell needle gage from degree of increasing, produce the bone stump separating force, correct the overlapping displacement of bone stump, then groove shape plate is placed the screw rod upper end that connects on the fixture block, fix with hex nut; Tighten capstan nut fixedly connection fixture block, the clamping plate that are fixedly connected of spiral shell pin, resected femur both sides again, bar is fixedly connected; Elasticity U bar is placed in the groove of the groove screw rod of tibiofibula both sides and long open slot screw rod, the assistant firmly closes up the groove screw rod of shank both sides and long open slot screw rod to the centre, at this moment rapidly the Kirschner wire that is through on the SOC.HD. cap screw with holes is twined a circle at screw rod, hex nut is fixed, and capstan nut is elasticity U bar fixedly, and the assistant unclamps then, at this moment hold in the palm frame, bullet frame, the outside isolating elastic force tension Kirschner wire of elasticity U bar, tighten the capstan nut of each one of resected femur tibia, hold-down screw, bolt; With knee sprung after the angle that the state of an illness needs, lock is opened each capstan nut of articulation femur external fixation part and tibia external fixation part, screw-driving is fixed, when fracture site relatively stable, can unclamp capstan nut and screw, the function of joint exercise of going down on one's knees is stretched in passive and active, lock opens the joint and has that the knee joint of making is fixed and the lock of loosening opens function, when fracture site has callus relatively stable, can remove the preaxial folding and become one-sided external fixation, when the Fracture of femur healing, can remove resected femur external fixation part and lock and open the joint, only stay the one-sided bone external fixation of tibia part, multifunctional lock opens combination bone external fixator also can separately be used for femur, tibia, humeral fracture bilateral or one-sided resetting and external fixation.
