Abstract
The utility model discloses a treatment centrum compression fracture's distraction device, including last arc and lower arc, be provided with first hinge in the bottom of last arc central authorities, two upper ends of going up the connecting rod simultaneously and first hinge hinged joint, its lower extreme respectively with two second hinge hinged joint, be provided with the third hinge at the top center of arc down, the lower extreme while and the third hinge hinged joint of two lower connecting rods, on it respectively with two second hinge hinged joint, the screw rod pass behind one of them second hinge with another second hinge threaded connection. The utility model discloses has set up last arc and arc down respectively according to the structure of human backbone centrum, during the operation, has made through rotatory screw rod and go up the arc and draw close each other with arc down and reduce, like this alright will go up arc and arc down and get into centrum fracture department through backbone centrum pedicle of vertebral arch passageway, the arc struts with arc down on this moment reverse rotation screw rod, resets the vertebra that compresses.
Description
Technical field
This utility model relates to a kind of device for spreading treating vertebral compression fracture, belongs to technical field of medical instruments.
Background technology
Spinal vertebral compression fracture is a kind of common disease, and all ages and classes has the vertebral fracture of heterogeneity and type.In the prior art, treatment spinal vertebral compression fracture is that in being close to expansion tube, inflation makes expansion tube expand, and dilated expansion tube, by the intravertebral reduction of compression, can effectively treat vertebral compression fracture.Its weak point is that expansion tube is when expanding in operation, and the as easy as rolling off a log bone damaged by fracture punctures and not expansion, causes operative failure, brings misery to patient.
Utility model content
The purpose of this utility model is, it is provided that a kind of simple in construction, the device for spreading of the treatment vertebral compression fracture that easy to operate, support effect is good, to overcome deficiency of the prior art.
The technical solution of the utility model: a kind of device for spreading treating vertebral compression fracture, including upper arc and arc lower plate, bottom center at upper arc is provided with the first hinge, with the first hinge chain connection while of two upper ends going up connecting rods, its lower end respectively with two the second hinge chain connections, center of top at arc lower plate is provided with the 3rd hinge, the lower end of two lower links simultaneously with the 3rd hinge chain connection, its upper end respectively with two the second hinge chain connections, screw rod is threadeded with another second hinge after passing through one of the second hinge.
The end face of described upper arc is arcwall face, and the bottom surface of arc lower plate is arcwall face.
The end of described screw rod is provided with handle.
Owing to using technique scheme, the utility model has the advantage of: this utility model is respectively provided with upper arc and arc lower plate according to the structure of human spine vertebral body, during operation, make upper arc and arc lower plate mutually draw close by rotary screw to reduce, the most just can upper arc and arc lower plate be entered at vertebral fracture through spinal vertebral pedicle channel, now on contra rotating screw, arc and arc lower plate strut, intravertebral reduction by compression, owing to the arcwall face of upper arc and arc lower plate can be fitted with vertebra when supporting vertebra, increase contact area, improve support effect, avoid causing vertebra secondary damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The upper arc of description of reference numerals: 1-, 2-arc lower plate, the upper connecting rod of 3-, 4-lower link, 5-the first hinge, 6-the second hinge, 7-the 3rd hinge, 8-screw rod, 9-handle.
Detailed description of the invention
In order to make this utility model purpose, technical scheme and advantage clearer, the utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment of the present utility model: the device for spreading structural representation for the treatment of vertebral compression fracture is as it is shown in figure 1, include arc 1 and arc lower plate 2, and the end face of described upper arc 1 is arcwall face, and the bottom surface of arc lower plate 2 is arcwall face；Bottom center at upper arc 1 is provided with the first hinge 5, with the first hinge 5 chain connection while of two upper ends going up connecting rods 3, its lower end respectively with two the second hinge 6 chain connections, center of top at arc lower plate 2 is provided with the 3rd hinge 7, the lower end of two lower links 4 simultaneously with the 3rd hinge 7 chain connection, its upper end respectively with two the second hinge 6 chain connections, screw rod 8 is threadeded with another second hinge 6 after passing through one of the second hinge 6, and the end of screw rod 8 is provided with handle 9.
During operation, first pass through rotary screw 8 to make arc 1 and arc lower plate 2 mutually draw close to reduce, the most just can upper arc 1 and arc lower plate 2 be entered at vertebral fracture through spinal vertebral pedicle channel, now on contra rotating screw 8, arc 1 and arc lower plate 2 strut, intravertebral reduction by compression, and the scope strutted is determined by the degree reversely rotated, owing to the arcwall face of upper arc 1 and arc lower plate 2 can be fitted with vertebra when supporting vertebra, increase contact area, improve support effect, it is to avoid cause spinal vertebral secondary damage.
