Description
Technical field
It the utility model is related to the technical field of external fixation used for orthopedics tool, and in particular to one kind is used for fracture fixation, deformity
The multiaxis dynamic external fixator for automatically adjusting expansion link of correction.
Background technology
Traditional treatment is fractured and the external fixator for orthopedics dep of malformation correction is roughly divided into from product structure outside unilateral combined type
Fixed mount, multilateral combinations external fixing rack and circular combined external fixing rack three major types are other.ILIZAROW toroidal frames are advanced skills
Art, although this technology can be completed from most simply to most complicated various fracture fixations and malformation correction, operation and use
Complexity, the amount of parts of product is more, and installation combination is cumbersome.
Publication No. CN202365897U is to overcome various shortcomings existing for traditional external fixing rack and ILIZAROW toroidal frame
And deficiency, there is provided a kind of simple to operate, surgical effect adjustable three dimensions external fixing rack in time, but length of telescopic bar
Adjustment is manually adjusted, thus, operation is cumbersome, it is necessary to constantly be adjusted manually according to reset procedure.
The content of the invention
In view of the drawbacks described above of prior art, the purpose of this utility model is to provide a kind of strong for fracture fixation, deformity
The positive multiaxis dynamic external fixator for automatically adjusting expansion link.
The purpose of this utility model is achieved through the following technical solutions：
A kind of multiaxis dynamic external fixator, including upper and lower baffle ring, olive pin, fine steel needle, needle rod holder and the six roots of sensation are stretched

It is threadedly coupled with corresponding universal cap 7, the universal cap 7 of left end is connected by bearing pin 15 with expansion link 8, and the universal cap 7 of right-hand member is logical
Bearing pin 15 is crossed to be connected with pillar 12；Expansion link 8 is internally provided with internal thread, and micromachine 10 is connected with nut 9, and nut 9 is set
There is external screw thread, nut 9 coordinates with the screw thread of expansion link 8；Micromachine 10 is arranged on inside pillar 12, and battery 11 is also disposed at pillar
Inside 12, powered to micromachine 10；Micromachine 10 drives nut 9 to rotate, and enables the expansion link 8 with the routing motion of nut 9
It is enough to carry out stretching motion relative to pillar 12；Pillar 12 is provided with sensor 13, and controller 14 is to micromachine 10 and sensor
13 are controlled in real time, stretching for the flexible bar component 5 of dynamic regulation, multiaxis dynamic external fixator is provided the life for having more bone uptake
Substance environment, promote bone growth.
But those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally
Utility model, and being not used as to restriction of the present utility model, if in spirit of the present utility model, to
Change, the modification of the upper embodiment will all fall in Claims scope of the present utility model.
