Nail；Forward and backward slide bar, middle part be sleeved on the most slidably in the forward and backward sliding rod hole of sliding shoe, slide
Have left bone screw holes on block, in left bone screw holes, have a left nail, forward and backward slide bar, between sliding shoe in have with front,
Rear slide bar, parallel screwed hole, screwed hole screws with the right-hand member of screw rod, and the left part of screw rod passes through the first sliding sleeve
Being fixed in bogie, the left end of screw rod fixes the first bevel gear, the second cone tooth engaged with the first bevel gear
Wheel is fixed in bogie by the second sliding sleeve, and the second bevel gear has six square grooves and the spiral shell coaxial with six square grooves
Pit, the bogie wall that six square grooves are corresponding has wrench insertion hole, and spanner can be inserted in six square grooves through inserting hole
In, with by first and second bevel gear driving screw rod, thus drive sliding shoe to slide, the axis hole of described spanner
Being inserted with lock-screw, lock-screw screws in the screwed hole of described second bevel gear internal clearance, in order to will
Spanner and the second bevel gear are fixed, and described bogie is fixed with described forward and backward slide bar by screw.
This utility model following advantages: 1), overcome the defect of extenal fixation, decrease complication, alleviate
The misery of patient；2), owing to being placed in outside periosteum, operation technique is simple, and wound is little, it is not necessary to destroy in bone marrow
Blood is transported；3), have certain moulding, facilitate metaphyseal extension osteotomy；4), by one piece of percutaneous screwdriver,
Realizing the regulation and control to inner fixing device, extending speed can arbitrarily control；5), reach to extend after purpose, take out
Screwdriver, fixing in transferring Guan Bi to, and can be fixing as termination, good looking appearance, nursing is convenient, has good
Value for clinical application.
