Description
Technical field
The present invention relates to technical field of medical instruments, and in particular to a kind of Study of Atlas Fracture by Finite fixator.
Background technology
Atlas is made up of anterior arch, cantle and two lateral mass.Unstable atlas blow-out fracture causes lateral mass of atlas to two
Side is shifted, and the dislocation of occipito-atlantoid articulations and articulatio atlantoepistrophica is caused, so as to influence the physiological function of upper cervical spine.In the prior art, utilize
Atlas list vertebra section follows closely the method for rod fixation to treat atlas bursting fracture, so that retain the physiological activity function of upper cervical spine, but this
Kind of fixing means is easily caused front fracture seam during the way of escape is held tightly and resetted and opened, it is impossible to realize anterior arch of atlas fracture
It is good to reset, cause anterior arch fracture not heal.
Chinese invention patent《Way of escape atlas reduction fixture device》(publication number：204744370U；Publication date：In November, 2015
11 days) in provide a kind of way of escape atlas reduction fixture device, the way of escape atlas reduction fixture device include left fixture, right fixation
Part, screw.The left fixture, right fixture include cross bar setting up and down and parallel and setting up and down for connecting
Cross bar brace.Keyway is provided with the cross bar on the top of the left fixture, the cross bar on the top of the right fixture is
One carries the projection of lock screw, and the raised and keyway is connected；Set on the left fixture, the brace of right fixture
Have and fixed loaded reset hole is clamped for level.Screw is used to be implanted into lateral mass of atlas.Although the way of escape atlas reduction fixture device can
With solve nail rod list vertebra section fixation can not realize bursting fracture physiology reset technological difficulties, but its exist it is very important
Shortcoming：Angle can not be adjusted after screw placement lateral mass of atlas, it is impossible to realize the good reset of anterior arch of atlas fracture.
Chinese invention patent《Arch of posterior atlas fixator》(publication number：202497224U；Publication date：On October 24th, 2012)
In provide a kind of arch of posterior atlas fixator, the arch of posterior atlas fixator by two same curvatures and suits face by stepped ramp type
The fixed plate of cooperation is constituted.Two pieces of fixed plates are fixed by the fixing screws being arranged on regulating tank, and the both sides of fixator are symmetrical
Screw is provided with, screw is located in the ball whirlpool fixed structure in screw.By analysis, the two fixed plates can be drawn
Stretch or bounce back, so that the reset of arch of posterior atlas fracture is realized, but anterior arch of atlas fracture is still unable to active homing.Total comes
Say, the active homing that anterior arch of atlas is fractured can not be realized by prior art, so that the therapeutic effect to Study of Atlas Fracture by Finite is produced not
Profit influence.
