Bone distal end comminuted fracture method is appeared and can not fixed with unilateral double-arm if cut in operation, need to be surpassed and be fixed outside ankle-joint, can
To unscrew long spiro nail in operation, extract and be not suitable for carbon rod, the carbon rod needed for insertion is then short with the folder connection of bar joining beam
Bar, cross, which is combined, couples adjustable steel nail connection folder at the two ends of quarter butt；The fixation of steel nail ten thousand is worn to root bone and contract bone or astragalus.
First support arm and the second support arm are carbon rod.
The present invention has the following effects that compared with prior art：The present invention can realize that each section of femur several sections of fracture wears steel nail
Outer fixation simultaneously can make fracture segment bone pressurize, and recover the overall physiology compression of femur, it is strong that unilateral double-arm locking can reach, stable outer
Fixed effect, improves cure rate.Existing single armed exterior fixing rack can not implement to wear several sections of fracture fixed outside steel nail, can not divide
Section bone pressurization, and the single armed treatment adjustable buckle bone pressuring external fixer of several sections of fracture of the present invention, can be any in several sections of fracture
Wear steel nail in position, it is possible to implement each fracture segment bone pressurization, recover the overall physiology compression of this long bone, such as Figure 32 promotes fracture
Healing；Existing single armed exterior fixing rack pressurizer length and it is heavy, for example, Zhong Jia exterior fixing racks, it is impossible to closely fractured in bone stump
Line wears steel nail, big because of intermediary press device length, limits nearly fracture site and wears steel nail, causes, away from steel nail is worn at fracture line, such as to scheme
Shown in 40, do not meet mechanics principle, fixation is not stable, so inapplicable, the external fixator of one's duty invention by contrast, volume
It is small, it is lightweight, steel nail can be worn close to any position of fracture line, fixation is stable；Existing single armed exterior fixing rack, pressurizer two
The design of extreme direction ball neck is thinner, therefore external fixing rack overally supports outer fixing intensity and weakened, such as Figure 40；Ring external fixation support
And multifunctional combined rack, greatly, multifunctional combined rack can not implement bone pressurization, such as Figure 41 to volume；Single armed exterior fixing rack pressurizer
The folder steel nail block of two ends multi-directional ball connection, it is impossible to according to the condition of the injury or the soft tissue injury change of being fractured in operation, it is impossible to change across bone
Steel nail length, such as Figure 40 are worn, using dumb therefore inapplicable；The external fixator of the present invention, finds to need to shorten in operation
Or increase outer fixed span fracture line length, long spiro nail can be unscrewed, inappropriate carbon rod is transferred to, such as Figure 26 changes long carbon
Plain rod, such as Figure 27, or short carbon rod, such as Figure 28, are flexibly used；Reinforcing carbon bar can combine that to be placed in pressure regulation Telescopic Fixed
Above device, treatment multistage femur external fixation of fracture can also be combined into, such as Figure 32, fabricated structure, can according to the fracture condition of the injury and
Carbon rod is reinforced the need for outer fixed drift bolt method, also be can be placed in below the Telescopic Fixed device of pressure regulation, it is solid outside composition unilateral double-arm
Determine femoral fracture, as shown in Figure 36 and Figure 37, strengthen exterior fixing rack intensity, it is flexible that steel nail is worn in outer fixation；Can be according to operation
Middle the fracture condition of the injury and soft tissue injury situation, select adjustable steel nail connection folder, or buckle steel nail folder, are placed in appointing for the first support arm
Position is selected, wears fixed outside steel nail to bone section, universal steel nail is disposed on the first support arm that adjustable telescopic fixator two ends couple
Fixture block, carry out outer resected femur stage casing or under, in upper 1/3 fracture, such as Figure 36；The of connection at pressure regulation Telescopic Fixed device two ends
Buckle steel nail fixture block is disposed on one support arm, carry out outer resected femur stage casing or under, in upper 1/3 fracture, such as Figure 37, pressure regulation is stretched
Contracting fixer structure is simple, with the loose long spiro nail of L right angles twisting, unilateral double-arm treatment several sections of fracture, adjustable buckle bone locking and pressurizing
External fixator, it can also be used to which fixed super ankle-joint is fixed, compared to ring type exterior fixing rack, small volume is easy to carry.
In summary, fixed mount small volume of the invention, lightweight, and adjustable universal steel nail folder and buckle steel nail folder wear steel nail
Flexibly, safety, simple to operate, easy to carry after expopexy, can reach that strong stable and mechanics is fixed, solve femur multistage
There is provided reliable treatment method for fracture.
