Abstract

The utility model belongs to an osteological medical appliance, and is composed of a horizontal adjustment screw, a vertical adjustment screw, a fixer, a coupling device and other auxiliary parts. The utility model not only provides a reasonable, simple, convenient and reliable medical appliance for doctors, but also is capable of alleviating patients' pains, and is especially capable of relieving the open reduction pain of early patients. Because the support holder has the characteristics of accurate fracture reduction, adjustment cure external force at any time, and functional exercise of injured fingers after operated at any time, the therapeutic effect is obviously superior to the other existing fixed modes.

Description

Campaign-styled adjustable phalanges exterior fixation bracket

This utility model belongs to orthopedic medical device.At present, treat Phalangeal fracture both at home and abroad and generally adopt open reduction internal fixation and clamping plate external fixation dual mode.The open reduction inner fixed law will cause periosteum and soft tissue injury, and union of fracture is slower; That resetting often appears in clamping plate external fixation rule is not good, fixing unreliable or skin is pressed wound, even blood fortune is not good causes pointing phenomenon such as necrosis.

The purpose of this utility model provides a kind of stressed direction-agile, the power value is adjustable at any time and constant magnitude, can proofread and correct various lopsided muscular strengths comprehensively and apply treatment external force effectively, and postoperative is hindered the phalanges exterior fixation bracket that refers to do functional exercise.

4. and 5. in this utility model, by the horizontal adjustment screw rod 1. exterior fixation bracket vertically adjusts screw rod, holder 2., 3. and 9., 7. coupling reaches other auxiliary spare part and forms.Adopt three pins to fix during operation, the interphalangeal joint fracture adopts the bilateral support to fix; The metacarpal bone articular fracture adopts single-side stand to fix.Three pieces of Kirschner wires (or screw) all should be walked crosswise from phalanges axis side and pass, and in the nearly joint of fracture line side, choosing is the center of circle a bit, walks crosswise and passes one piece of Kirschner wire, so that as the active center of exterior fixation bracket; On other two pieces of appropriate locations that then should be located at fracture line joint far away side.By adjusting the relative position between each holder in the support---relative distance and relative angle (following all with) can reach proper reset, rationally apply and treat external force and fixed purpose.

Compared with prior art and since in this support holder 2. and (or screw) A of the Kirschner wire 9. and C 4 degree of freedom are respectively arranged, Kirschner wire (or screw) B of holder in 3. has 6 degree of freedom to adjust.Therefore, the utlity model has and reset accurately and reliably, application of force size, direction are adjustable at any time and the power value is constant, and postoperative hinders to refer to be series of advantages such as movable.In addition, because the position precision that this utility model the time is threaded a needle to operation is less demanding, therefore be convenient to doctor's operation.For fresh closed fracture patient, can also exempt the hardship of open reduction.

As shown in the figure, figure one fixes for double bracket, and figure two fixes for single-side stand.

1. 7. coupling of horizontal adjustment screw rod

2. 8. packing ring of holder A

3. 9. holder C of holder B

4. vertically adjust screw rod M 10. Kirschner wire or screw rod A

5. vertically adjust screw rod N Kirschner wire or screw rod B

6. jump ring Kirschner wire or screw rod C

Below in conjunction with figure one, be elaborated to realizing preferred plan of the present utility model.

Figure one is two fixed support treatment middle phalanx basilar part bone fracture bone fracture disease illustration intentions.During operation, walk crosswise at heart place, circle garden, proximal phalanx head side earlier and penetrate one piece of Kirschner wire C, walk crosswise in middle joint fracture distally side, phalanges center line appropriate location then and penetrate other two pieces of Kirschner wire A and B.Adjust the relative position between each holder in the exterior fixation bracket, from the both sides that wound refers to one pack support is installed respectively respectively.By adjusting relative distance and the angle between each holder once more, can reach the purpose that makes the fracture proper reset and rationally apply treatment external force.Two pack supports are placed respectively hinder the appropriate location refer to both sides, cut off the Kirschner wire of holder Outboard Sections, and suitable flattening (exceeding to prevent that support from coming off) is done at its two ends.Can also at any time the relative position between the Kirschner wire be adjusted as required in the therapeutic process, to guarantee optimum therapeuticing effect.Adopt this kind method operation and fixing, the postoperative wound refers to carry out functional exercise and exercise, thus the healing that can quicken to fracture.After treating union of fracture, can Kirschner wire be extracted from the other end behind the homalocephalus of removal Kirschner wire one end.

Single-side stand is fixed, and then is difficult for adopting Kirschner wire, and should adopts screw (as figure two).Its principle and method are all same with the double bracket immobile phase.

Claims

1,4., 5. by the horizontal adjustment screw rod 1. campaign-styled adjustable phalanges exterior fixation bracket, vertically adjust screw rod, holder 2., 3., 9., 7. coupling reaches other auxiliary component and forms.Of the present utility model being characterised in that, by adjusting screw rod 1., 4., 5., adjust external fixator 2., 3., the relative position between 9., thereby adjust the relative position between each Kirschner wire in the support or the screw and apply treatment external force, guarantee simultaneously to hinder and refer in therapeutic process, can move.

2, as claims 1 described exterior fixation bracket, its feature is that also each holder is that 1. horizontal range and the treatment external force between Kirschner wire or the screw can be adjusted by the horizontal adjustment screw rod.

3, as claims 1 described exterior fixation bracket, its feature is that also 4. and 5. the vertical dimension between each holder can be adjusted by vertical adjustment screw rod with treatment external force.

4, as claims 1 described exterior fixation bracket, its feature also is, the horizontal adjustment screw rod 1. with vertical adjustment screw rod 4. between, 9. connect by coupling.

5, as claims 1 described exterior fixation bracket, its feature also is, intermediate securement in 3. Kirschner wire or 6 degree of freedom of screw , two end fixators 2., the Kirschner wire in 3. or screw 10., 4 degree of freedom of , all can adjust as required.
