Abstract
The invention discloses a calcaneus orthopaedics ring bar combined external fixation support comprising an upper ring piece and a lower ring piece connected with the upper ring piece through a fixing member; two ends of the upper and lower ring pieces are respectively provided with a plurality of screw holes; the screw hole is provided with a needle clamp cover; the bottom of the needle clamp cover is provided with a plurality of needle slots; a bone spicule is arranged in each needle slot. The upper and lower ring pieces are interlaced so as to adapt to relative angle and position changes of fracture bone spicule fixation, thus positioning the calcaneus bone blocks in different directions, lengths and angles; the calcaneus orthopaedics ring bar combined external fixation support is simple in structure, and convenient in adjusting.
Description
Technical field
The present invention relates to a kind of calcaneus orthopaedics ring rod combination exterior fixation bracket.
Background technology
During fracture of calcaneus, especially serious fracture is pulverized, mostly along with the upper and lower displacement of skeleton or angular misalignment, clinician is needed to carry out anatomical reduction to its position in operation, this orthopedic instrument with regard to needs specialty fixes the skeleton of reset, help skeleton recover as early as possible and heal, orthopaedics ring rod combination exterior fixation bracket is one of medical apparatus and instruments that Orthopedic Clinical is conventional.
At present, the orthopaedics ring rod combination exterior fixation bracket that market is commonly used is all connected by a craspedodrome main body between two folder pin blocks mostly, generally there is following shortcoming: 1, the distribution of spicule is generally kept straight on exactly or vertically fixed; 2, craspedodrome main body can not do angle change.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, a kind of calcaneus orthopaedics ring rod combination exterior fixation bracket is provided, the spicule of fixing fracture can be realized, can adjusting angle and adapt to the change of relative position, thus reach and locate flexibly, increase subject range, structure is simple, easy to adjust.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of calcaneus orthopaedics of the present invention ring rod combination exterior fixation bracket, the lower ring block comprising pressed on ring block and be connected by fixture with described pressed on ring block, the two ends of described pressed on ring block and described lower ring block are equipped with several screws, described screw is provided with pin folder lid, the bottom of described pin folder lid is provided with several needle trays, is provided with spicule in described needle tray.
As the preferred a kind of technical scheme of the present invention, the middle part of described pressed on ring block is provided with annular groove, and the middle part of described lower ring block is provided with lower annular groove; Described fixture is bolt assembly, and described fixture is also fixed through described upper annular groove and described lower annular groove.
As the preferred a kind of technical scheme of the present invention, the arranged outside of described upper annular groove has step trough.
As the preferred a kind of technical scheme of the present invention, the inner side of described pressed on ring block is provided with toothed surfaces, and the inner side of described lower ring block is provided with lower toothed surfaces, and described upper toothed surfaces contacts with described lower toothed surfaces.
As the preferred a kind of technical scheme of the present invention, described pin folder lid is fixed on described screw by lock-screw scalable.
The invention has the beneficial effects as follows: by intersecting the upper and lower ring block installed, can adapt to the fixing fracture relative angle of spicule and the change of position, finally can reach the different directions length of calcaneus bone block and the location of angle, structure is simple, easy to adjust.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of calcaneus orthopaedics of the present invention ring rod combination exterior fixation bracket, the lower ring block 2 comprising pressed on ring block 1 and be connected by fixture 3 with described pressed on ring block 1, the two ends of described pressed on ring block 1 and described lower ring block 2 are equipped with several screws 5, described screw 5 is provided with pin folder lid 6, the bottom of described pin folder lid 6 is provided with several needle trays 61, is provided with spicule 4 in described needle tray 61.
The middle part of described pressed on ring block 1 is provided with annular groove 13, and the middle part of described lower ring block 2 is provided with lower annular groove 21; Described fixture 3 is bolt assembly, and described fixture 3 is also fixed through described upper annular groove 13 and described lower annular groove 21.Upper annular groove 13 and lower annular groove 21 are bar-shaped trough, also can regulate in certain angular range by bolt activity is fixing.
The arranged outside of described upper annular groove 13 has step trough 15.The inconvenience in life is caused in order to avoid outstanding stud.The stud head of stud is placed in step trough 15, ensures the planarization of outer surface of the present invention.
The inner side of described pressed on ring block 1 is provided with toothed surfaces 14, and the inner side of described lower ring block 2 is provided with lower toothed surfaces 22, and described upper toothed surfaces 14 contacts with described lower toothed surfaces 22.Upper toothed surfaces 14 contacts with lower toothed surfaces 22 is concavo-convex, produces larger friction, the angle set by guarantee.
