It is convenient
In some embodiments：Upper ring movable block side is provided with curved angle graduation mark, and lower rod assembly is provided with and arc
The zero graduation line that shape angle index line coordinates.Thus, it is possible to intuitive and convenient observe and read ring movable block with lower rod group
The angle rotated against between zoarium.
The present invention can adjust the angle of spicule, become to adapt to fix the adjustment of relative angle and position of fracture deformity
Change, can finally reach positioning and the reset of the different angles of long bone, it is simple structure, easy to adjust.
Brief description of the drawings
Fig. 1 is the structural representation that a kind of orthopaedics ring rod of the invention combines exterior fixing rack；
Fig. 2 is the side view that a kind of orthopaedics ring rod of the invention combines exterior fixing rack；
Fig. 3 is a kind of structural representation of the curved angle graduation mark of orthopaedics ring rod combination exterior fixing rack of the invention.
Specific embodiment
Illustrate below in conjunction with the accompanying drawings, the present invention is described in further detail.
As Figure 1-3, a kind of orthopaedics ring rod combination exterior fixing rack, including upper ring movable block 1, the lower and of rod assembly 2
Drive mechanism, upper ring movable block 1 is arranged at lower rod assembly 2 by rotating shaft 13, and specifically, rotating shaft 13 can be fixed and is arranged in
Upper ring movable block 1, lower side assembly 2 upper end offers mounting groove, and the relative two side wall of mounting groove offers axis hole, turns
The two ends of axle 13 are inserted in two axis holes respectively, to be flexibly connected between rotating shaft 13 and axis hole, that is to say, that rotating shaft 13 can be
Rotated in axis hole, rotating shaft 13 in addition can also be installed in axis hole by bearing.Drive mechanism can drive ring movable block 1 around
Rotating shaft 13 is rotated, and drive mechanism may be mounted in the mounting groove of lower side assembly 2.Upper ring movable block 1 is symmetrically arranged with two
Spicule group, spicule group can be moved back and forth on upper ring movable block 1.It is solid to adapt to thereby, it is possible to adjust the angle of spicule 6
Determine the adjustment change of the relative angle and position of fracture deformity, can finally reach positioning and the reset of the different angles of long bone, tie
Structure is simple, easy to adjust.
Wherein, drive mechanism can include being arranged at the worm gear 11 of ring movable block 1 and be arranged at lower rod assembly 2
Worm screw 5, worm screw 5 engages with worm gear 11.Specifically, turbine 11 can be shaped in or be spirally connected and be fixed on ring movable block
1 downside, turbine 11 is the sector structure as the center of circle with rotating shaft 13, on the outside curve of turbine 11 can integrally formed with or open
It is provided with turbo tooth 111.The two ends of worm screw 5 are movably connected on the relative two side wall of the mounting groove of lower side assembly 2, that is,
Say that worm screw 5 can be integrally formed or offer the worm tooth 51 engaged with turbo tooth 111 with radial rotating, the surface of worm screw 5.Using
When, rotary worm 5 can be such that turbine 11 13 rotates around the shaft, also just drive upper ring movable block 1 13 to rotate around the shaft, be adjusted with this
The angle of spicule 6 is saved, to adapt to fix the adjustment change of the relative angle and position of fracture deformity, long bone can be finally reached
The positioning of different angles and reset, it is simple structure, easy to adjust.
Wherein, spicule group includes arc chute 12, needle stand 7 and spicule 6, and arc chute 12 is opened in ring movable block 1, arc
The axial symmetry of shape chute 12 is set, and needle stand 7 is slideably positioned in arc chute 12, and spicule 6 is inserted in needle stand 7, and needle stand 7 is provided with and limits it
