To temporarily fixed purpose, need to be disposed if filling in gauze ball and cannot all stablize angulation displacement according to serious splintered fracture.It is right
Support can not be formed between serious splintered fracture, bone piece, needs to take integral reset thought at this time, at this time, it is proposed that using multiple
The Type B of position baffle 4, interim fixed plate 3 preferably select longer Type B or D types, and lower clamp pincers tooth 14 selects A types or c-type, it is necessary to first
Reduction forceps are integrally preset in fracture site, one piece of forcing screw is inserted in wherein side pressurization screw hole 33 after prejudging position,
Then bone fundamental length, rotation and axis are recovered by manual traction, standard reset is clamped with one immediately after basic reset will
Fracture other end backbone is clamped with interim fixed plate 3, and clamp position can avoid sliding at flat groove 34, after clamping, by fracture segment
Broken bone piece try one's best split reset, if it is undesirable unclamp standard reset pincers repeat the above process again, by lower pincers after being satisfied in the main
Body 1 closes up, and the auxiliary of push-tight reseting baffle 4 stablizes the broken ends of fractured bone, then is reached by rationally inserting forcing screw in interim fixed plate 3
Fixed purpose temporarily.
When carrying out temporary setting operation, one piece of Kirschner wire, the effect of Kirschner wire fixation can be inserted in kirschner pin hole 32
Have at 2 points：One is auxiliary control folding end is swung, blocked the second is soft tissue can be carried out, reduce assistant and drag hook uses, if bone
Folding resets ideal, can be directly fixed in bilateral pressurization screw hole 33, at this time, Kirschner wire mono cortex is fixed；If reset not
It is very preferable, then it can be finely adjusted, but principle is：Accomplish to be satisfied with reset before fixation as far as possible, can not adjusted or not, to subtract
Few bone iatrogenic injury.
For needing adjustment person：If Fracture Simple and general comminuted fracture, first followed closely simultaneously on side pressurization screw hole 33
Pressurization, the double cortex of one piece of Kirschner wire are fixed on homonymy, then offside slide laterally hole 35 or longitudinal sliding motion hole 37 pressurizeed,
The fine setting such as separation or rotation (aftermentioned), forcing screw is fixed on the pressurization screw hole 33 of sliding eye adjustment side after adjustment, should
The no longer upper Kirschner wire auxiliary in side；If serious splintered fracture, fracture segment can not form support after resetting, and insert pressurization spiral shell
One piece of double cortex of Kirschner wire progress is fixed on nail side, and then sliding laterally hole 35 or longitudinal sliding motion hole 37 in offside is added
Pressure, separation or rotation adjustment, nut sink to the screw hole stage it is synchronous slowly unclamp standard reset pincers, reach after adjustment effect in cunning
Forcing screw is fixed on the pressurization screw hole 33 of dynamic hole adjustment side, the no longer upper Kirschner wire auxiliary in the side.
After the completion of interim fix, reversely rotating interim fixed plate fixing screws 31 makes interim fixed plate 3 and upper clamp " U "
Type tooth 21 dissociates, and unclamps the nut 24 of locking screw, exits back reduction forceps.Doubling end again may be needed for comminuted fracture
The broken secondary reset of bone piece, at this time the length of bone recovered, folding end stress concentration in interim fixed plate 3, having interim fixed plate 3
The reset of broken bone piece becomes easy under support, and longer dissection armor plate or reconstruction plate should be selected to carry out most after the completion of secondary reset
It is fixed eventually, it can pull down interim fixed plate 3 after the completion of finally fixing.
Need to pressurize to fracture segment, separated or be rotated adjustment during fine setting：Hole 35 is being slid laterally close to fracture end
A Slideslip pressurization can be achieved folding end separation, sliding laterally hole 35 away from fracture end a Slideslip pressurization can be achieved folding
The pressurization at end；When needing to adjust rotation angle, can be realized by longitudinal sliding motion hole 37：Reaching rotation purpose merely can be in longitudinal direction
Realized by different boring directions at the middle part of sliding eye；Adjust rotation at the same time and lateral displacement can be in the upper of longitudinal sliding motion hole
Realized with reference to bore angle lower both sides.
In theory, carry out interim stability maintenance more with lock hole, but lock screw it is repeatedly elastic after inevitably occur without
Screw hole stripped thread, locking failure even cold welding situations such as can not removing, if reliable guarantee can be obtained in technique, with lock hole into
The interim fixation of row should be used as first choice.
Above-described embodiment is only used for further illustrating a kind of integrated fracture reduction fixing clamp of the present invention, but the present invention is simultaneously
Embodiment is not limited to, every any simple modification made according to technical spirit of the invention to above example, equally become
Change and modify, each fall within the protection domain of technical solution of the present invention.
