Abstract
The utility model discloses an external fixing support used for calcaneus fracture, which forms a triangular support from a knighthead (7), a transverse knighthead (1) and an inclined knighthead (2) by a corneous connecting piece (8) and two groups of adjustable connecting components, wherein, one end of the knighthead (7) is connected with one end of the transverse knighthead (1) by the corneous connecting piece, the other end of the knighthead (7) is connected with the inclined knighthead (2) by the adjustable connecting component, the other end of the transverse knighthead (1) is connected with the other end of the inclined knighthead (2) by the other adjustable connecting component; an adjustable compression block (13) is arranged on the transverse knighthead (1); and the corner position of the corneous connecting piece (8) is provided with a needle incoming hole (10). The utility model uses the transverse knighthead to add a backward holding power, thereby achieving the aim of not only being capable of recovering the length of the calcaneus, but also being capable of recovering the B*hler angle (B*hler angle).
Description
Technical field
This utility model relates to technical field of medical instruments, belongs to a kind of exterior fixation bracket that is used for fracture of calcaneus.
Background technology
The common clinically fracture of calcaneus comminuted fracture formula because of its fragment is many, involves each articular surface, and reset effect is very undesirable, and the purpose of treatment is shape and Bei Shi angle (the B hler angle) of recovering calcaneus.Method is a lot, concludes to get up to have three kinds: 1. manual reduction, small splints fixation; 2. operative reduction internal fixation; 3. the manual reduction support arm is fixed.Manual reduction, small splints fixation are applicable to the fracture of calcaneus that displacement is little, and the comminuted fracture of calcaneus for involving articular surface is difficult to reach ideal effect.Operation only is applicable to those fractures of calcaneus that osteomiosis piece is few, fragment is bigger, and the most fragment of calcaneus comminuted fracture is many and little, thus be difficult to reset and fix, and have the otch easy infection and the complication of disunion.The manual reduction support arm is fixed, and it has expectant treatment and the fixed advantage of operation, is reasonable Therapeutic Method.Support arm in the past only notes recovering the Bei Shi angle (B hler angle) of calcaneus mostly, has ignored the recovery of anteroposterior diameter, and its reset effect is not satisfactory.
Summary of the invention
The purpose of this utility model provides a kind ofly can recover Bei Shi angle (B hler angle), can recover the exterior fixation bracket that is used for fracture of calcaneus of the length of calcaneus again.
The purpose of this utility model is to realize like this, it is by dihedral connector and two groups of scalable coupling assemblings left support bar, right support bar and transverse supporting rod to be constituted triangular supports, left side support bar one end is fixedlyed connected by a dihedral connector with right strut one end, the left side support bar other end is connected by the scalable coupling assembling with transverse supporting rod one end, and right support bar one end is regulated coupling assembling with the transverse supporting rod other end by another and is connected; The adjustable compression piece is housed on the transverse supporting rod; Described dihedral connector rotation angle position is provided with the inserting needle hole.
According to clinical observation and pathological analysis, its support force weakens after finding the calcaneus comminuted fracture, the shortening of anteroposterior diameter is arranged mostly, so, this utility model is designed to triangle, and be the exterior fixation bracket that can regulate, can satisfy has a pull strength under backward on the calcaneus, and the requirement of the compression stress of bone inboard.Thereby reach the length that to recover calcaneus, can recover the purpose at Bei Shi angle (B hler angle) again,, obtained extraordinary effect through clinical verification.

The specific embodiment
Embodiment
With reference to Fig. 1, present embodiment is by dihedral connector 8 and two groups of scalable coupling assemblings support bar 7, transverse supporting rod 1 and inclined support bar 2 to be constituted triangular supports.Support bar 7 one ends are connected by a dihedral connector 8 with transverse supporting rod 1 one ends, and support bar 7 other ends are connected by the scalable coupling assembling with inclined support bar 2 one ends, and transverse supporting rod 1 other end is regulated coupling assembling with inclined support bar 2 other ends by another and is connected.Described support bar 7, transverse supporting rod 1 and inclined support bar 2 are screw mandrel.Described every group of scalable coupling assembling is by a plate 4 and the two pairs of nuts 3,3 ' form.Described connecting plate bending is arcuation, and connecting plate plate face is provided with two installing holes, and the one end is provided with locating hole 6, and 6 places are provided with thimble 5 at described locating hole.When support bar 7 assembled with the scalable coupling assembling, support bar 7 other ends passed a nut 3 successively
1, an installing hole and another nut 3 on the connecting plate 4
2When inclined support bar 2 assembled with the scalable coupling assembling, inclined support bar 2 one ends passed a nut 3 successively
3, another installing hole and another nut 3 on the connecting plate 4
4Transverse supporting rod 1 other end and inclined support bar 2 other ends and another assembling of regulating coupling assembling are same as above.Described dihedral connector 8 rotation angle positions are provided with inserting needle hole 10, and 10 places are provided with thimble 9 in described inserting needle hole.Support bar 7 one ends and dihedral connector 8 one ends are for fixedlying connected.Transverse supporting rod 1 passes compression blocks 13 by 8 other end clampings of dihedral connector, and fixedly connected by screw 14.By horizontal support compression blocks 13 is nut.With reference to Fig. 2, during use, respectively place exterior fixation bracket of the present utility model in two sides of patient's foot 12.Get calcaneal tuberosity, 10cm the posterior aspecct of the tibia on the ankle, the first cuneiform mid point is an entry point, with diameter 3.5mm Kirschner wire 11, vertically pierce the offside that passes limbs, two ends of Kirschner wire 11 pass the inserting needle hole 10 of the dihedral connector 8 of two side exterior fixation bracket respectively then, by thimble 9 Kirschner wire 11 and exterior fixation bracket are fixed.The Kirschner wire that will connect with thimble 5 in the locating hole 6 of connecting plate of patient's foot two side exterior fixation bracket is fixed.The fixing angle of ankle, support bar 7 and transverse supporting rod 1 are pushed calcaneal tuberosity to rear and below respectively, form making a concerted effort under backward, both solved the problem at Bei Shi angle (B hler angle), compression recovers before and after also making, in the middle of inside and outside two side direction, push, to solve the problem to the displacement of inside and outside both sides of fracture of calcaneus.
