A kind of external fixing rack for being used to correct long bone malformation, for long bone knochenbruch to be fixed, including fixed pin and stock, the stock sets two, and hinged by axis, stock is connect with fixed pin by clamp device, a wherein root long bar is divided into the first stock and the second stock, and first stock is connect with the second stock swivel nut, and the utility model is during fixation of bone fragments, it only needs to adjust swivel nut, it is easy to operate.
Description
Technical field
The utility model is related to a kind of external fixers for long bone correction, belong to the field of medical instrument technology.
Background technology
External fixing rack in fixed fracture or correction bone malformation, correcting long bone malformation, be by long bone be cut into two sections or
Two sections or more, and two sections of bones are in contact with each other in correct position, to allow the formation of fibrocartilage poroma, external fixing rack will
Ask be conveniently operated, it is firm it is firm, convenient for not staying foreign matter in Wound during Dressing Change, tissue, and need to prevent pin site infection, convenient for tune
It is whole.Existing external fixing rack part is more, inconvenient.
Utility model content
The utility model is directed to the defect of the prior art, provide it is a kind of for correcting the external fixing rack of long bone malformation, zero
Part is less, is easy to be conveniently operated.
Technical problem described in the utility model solves by the following technical programs：
A kind of external fixing rack for being used to correct long bone malformation, including fixed pin and stock, the stock setting two, and
Hinged by axis, stock is connect with fixed pin by clamp device, wherein a root long bar is divided into the first stock and second
Stock, first stock are connect with the second stock swivel nut.
The above-mentioned external fixing rack for being used to correct long bone malformation, the clamp device include trip bolt, positioning disk and fastening
Disk, the positioning disk are fixedly connected with trip bolt, and fastening plate is threadedly coupled with trip bolt.
Above-mentioned for correcting the external fixing rack of long bone malformation, the trip bolt is connect with long rod sleeve, and fixed pin clamps
Between positioning disk and fastening plate.
The utility model has the following advantages：
The utility model sets fixed pin to be repositioned with stock to draw long bone section, and two section of fixed long bone
Relative position makes knochenbruch be unlikely to askew in agglutination and splits, and stock sets two, and two root long bars can be same vertical flat
It is freely up and down movable in face, wherein a root long bar is divided into the first stock and the second stock, spiral shell between the first stock and the second stock
Set connection after fixed pin fixes knochenbruch, connects into obtuse angle between two root long bars, adjusts swivel nut, long articular cortex weight at this time
New connection is fixed, and the utility model only needs to adjust swivel nut in fixation procedure, easy to use.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model clamp device structure diagram.
Each label is expressed as in figure：1st, fixed pin, 2, stock, 2-1, the first stock, 2-2, the second stock, 3, tight
It is fixedly mounted with and puts, 4, trip bolt, 5, swivel nut, 6, axis, 7, positioning disk, 8, fastening plate.
Specific embodiment
It is a kind of that for correcting the external fixing rack of long bone malformation, including fixed pin 1 and stock 2, the stock 2 sets two,
And hinged by axis 6, stock 2 is connect with fixed pin 1 by clamp device 3, wherein a root long bar 2 divides for the first length
Bar 2-1 and the second stock 2-2, the first stock 2-1 are connect with the second stock 2-2 swivel nuts 5.
The clamp device 3 includes trip bolt 4, positioning disk 7 and fastening plate 8, and the positioning disk 7 is solid with trip bolt 4
Fixed connection, fastening plate 8 are threadedly coupled with trip bolt 4.
The trip bolt 4 is connect with 2 axle sleeve of stock, and stock 2 can rotate on trip bolt 4, and fixed pin 1 is clamped in
Between positioning disk 7 and fastening plate 8.
Bolt 4 is inserted into stock 2, rotatable between bolt 4 and stock 2, and stock 2 and fastening bolt 4 are always in company
State is connect, when needing that knochenbruch is fixed, two fixed pins 1 is fixed on first the suitable position of knochenbruch, makes two root longs
Bar 2 until positioning disk 7 is close to fixing glue 1, screws fastening plate 8 close to fixed pin 1 later, and fixed pin 1 is made to be fixed with respect to bolt 4,
At this point, two root long bars 2, into obtuse angle, when rotating swivel nut 5, stock 2 shortens, since stock 2 can be in perpendicular freely up and down
Activity, two root long bars 2 are first into horizontality, then screw swivel nut 5, make to be completely embedded at knochenbruch, and long articular cortex reconnects solid
It is fixed, after knochenbruch is grown well, remove this external fixing rack.
