Abstract
The utility model discloses a way of escape extensive region vertebra fixer that resets, this way of escape extensive region vertebra fixer that resets include left mounting, right mounting, universal screw, set up about a left side mounting, right mounting are and parallel horizontal pole and be used for connecting about the down tube of the horizontal pole that sets up, be provided with the keyway on the horizontal pole on the upper portion of left side mounting, the horizontal pole on the upper portion of right side mounting is an arch that has the locking screw, the protruding cooperation with the keyway is connected, be provided with on the down tube of a left side mounting, right mounting and be used for the fixed pressurization of the level pincers hole that resets, the horizontal pole of left side mounting, right mounting lower part is fixed through universal screw extensive region vertebra lateral mass. The utility model discloses the fixed technological difficult point that physiology resets of fracturing that can't realize bursting of present nail stick single vertebra festival has also been solved in the mobility forfeiture of both having avoided adopting neck pillow fusion or extensive region dentata fusion to cause.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of way of escape atlas reduction fixture device.
Background technology
Atlas bursting fracture often, caused by traffic accident and high pendant wound, deals with comparatively thorny.Previously usually adopt occipito―cervical fusion or atlanto―axial fusion treatment, but above method can make patient lose most of cervical vertebra moving function.At present, new rise utilizes atlas list vertebra to save the fixing method of nail rod to treat atlas bursting fracture, thus retain the physiological activity function of upper cervical spine, but this fixing means is held tightly in the process of reset in the way of escape and is easily caused front seam of fracturing to open, thus cause fracture to heal.
There is no good operating theater instruments at present and can evade the problems referred to above.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of way of escape atlas reduction fixture device.
For achieving the above object, the technical solution of the utility model is achieved in that
This utility model embodiment provides a kind of way of escape atlas reduction fixture device, this way of escape atlas reduction fixture device comprises left fixture, right fixture, Universal screw nail, described left fixture, right fixture are setting up and down and parallel cross bar and the brace for connecting cross bar setting up and down, the cross bar on the top of described left fixture is provided with keyway, the cross bar on the top of described right fixture is one with the key of lock screw, and described key and keyway are connected; The brace of described left fixture, right fixture is provided with for the fixing loaded reset hole of level pincers, the cross bar of described left fixture, right fixture bottom is fixed by Universal screw nail lateral mass of atlas.
In such scheme, the thickness of the key of described right fixture is lower than the thickness of the cross bar on left fixture top.
Compared with prior art, the beneficial effects of the utility model:
This utility model had both avoided the mobility adopting occipito―cervical fusion or atlanto―axial fusion to cause to lose, and also solved the fixing technological difficulties that cannot realize bursting fracture physiology and reset of the excellent single vertebra joint of nail at present.
Accompanying drawing explanation
Fig. 1 provides a kind of structural representation of way of escape atlas reduction fixture device for this utility model embodiment;
Fig. 2 provides a kind of structural representation of left fixture of way of escape atlas reduction fixture device for this utility model embodiment;
Fig. 3 provides a kind of structural representation of right fixture of way of escape atlas reduction fixture device for this utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
This utility model embodiment provides a kind of way of escape atlas reduction fixture device, as shown in Fig. 1 ~ 3, this way of escape atlas reduction fixture device comprises left fixture 1, right fixture 2, Universal screw nail 3, described left fixture 1, right fixture 2 are setting up and down and parallel cross bar and the brace for connecting cross bar setting up and down, the cross bar on the top of described left fixture 1 is provided with keyway, the cross bar on the top of described right fixture 2 is one with the key 5 of lock screw 4, and described key 5 is connected with keyway; The brace of described left fixture 1, right fixture 2 is provided with for the fixing loaded reset hole 6 of level pincers, the cross bar of described left fixture 1, right fixture 2 bottom is fixed by Universal screw nail 3 lateral mass of atlas.
The thickness of the key 5 of described right fixture 2 is lower than the thickness of the cross bar on left fixture 1 top.
Described left fixture 1, right fixture 2 lateral symmetry are provided with the screw for arranging Universal screw nail 3, and described Universal screw nail 3 inserts lateral mass of atlas by screw, and realize locking by the ball whirlpool fixed structure of Universal screw nail 3;
Described loaded reset hole 6 is for making way of escape atlas reset by loaded reset hole clamp.
After completing reset, make whole way of escape atlas reduction fixture device become a firm entirety by locking lock screw 4, thus ensure the reset mode maintaining fracture.
Implementation process of the present utility model:
Surgical exposure arch of posterior atlas, prepares Atlas vertebral pedicle screw nail road, both sides with passage-opening awl and screw tap; Left fixture 1, right fixture 2 are placed in side arch of posterior atlas respectively, make Universal screw nail 3 aim at nail road enter to follow closely mouth, insert the Universal screw nail 3 of bilateral and lock Universal screw nail 3; With towel forceps clamp left fixture 1, two loaded reset holes 6 of right fixture 2 carry out loaded reset, now, described left fixture 1, right fixture 2 are drawn close to centre by the cooperation of keyway and key 5, are driven the atlas integral level of explosion to draw close to centre to realize physiology to reset by Universal screw nail 3; After reset completes, lock screw 4 is locked, make the entirety that reduction fixture device becomes firm, thus maintain the reduction of the fracture state of atlas.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
