Abstract
A resetting rod for a thoracolumbar vertebral fracture minimally invasive surgery comprises a main body. The main body comprises a transverse rod and a vertical rod fixed on the transverse rod. The main body is of a T-shaped structure, and the vertical rod is of a hollow round tube structure. A hollow opening communicated with the vertical rod is arranged on the transverse rod, and a U-shaped groove is arranged at the lower end of the vertical rod. The resetting rod is reasonable and simple in structure, a hollow sleeve is inserted, and the U-shaped groove is clamped at the back of the vertical rod to prevent rotation. Further, clamp ring design is arranged on the vertical rod, so that the resetting rod can be unfolded conveniently. A middle column in front of the fractured vertebral can be effectively unfolded, and the resetting rod is convenient to operate. The resetting rod is simple in structure, convenient to operate and safe to apply, fills the blank in the field and is worth popularizing and applying.
Description
Technical field
This utility model relates to a kind of medical devices, especially a kind of release link that is used for the lumbar vertebra compression fracture Minimally Invasive Surgery.
Background technology
In lumbar vertebra compression fracture, usually go posterior approach clinically; And treat the more and more way of escape Minimally Invasive Surgerys that use of lumbar vertebra compression fracture at present clinically; Go back the good way of escape Minimally Invasive Surgery of neither one repositioning method now, posterior approach is had relatively high expectations to hindering resetting of vertebra, if it is bad to reset; Then can residual kyphosis deformity, influence the recovery of function.
The spinal operation Wicresoft internal fixation system of several external introductions of using clinically at present, like Sextent system, SPIRIT system etc., because used universal screw, complicated operation is loaded down with trivial details when resetting, and reset strength a little less than, the satisfaction that can not obtain to hinder vertebra resets.This accomplishes with regard to the lumbar vertebra compression fracture Minimally Invasive Surgery release link that needs a simple and convenient practicality and hinders resetting of vertebra, promptly reaches the satisfied vertebra of hindering and resets.
Summary of the invention
This utility model will solve the shortcoming of above-mentioned prior art, and a kind of lumbar vertebra compression fracture Minimally Invasive Surgery release link is provided, and satisfies clinical demand.
This utility model solves the technical scheme that its technical problem adopts: this lumbar vertebra compression fracture Minimally Invasive Surgery release link; Comprise main body; Main body comprises cross bar, is fixed on the montant on the cross bar, and wherein main body is T font structure, and wherein montant is the hollow cylinder structure; And have on the cross bar communicate with montant in eat dishes without rice or wine, wherein the lower end of montant is provided with the U-shaped groove.The T-shaped spanner shape of this structure; The U-shaped groove of montant lower end can be inserted in the tail end passage place of the pedicle screw in the mini-incision; And the U-shaped groove blocks on the vertical rod; Put into nut in can therefrom eating dishes without rice or wine, this reposition lever can also prevent that when resetting vertebral fracture rotation from appearring in screw when screwing in nut.
After strutting merely in the lumbar vertebra compression fracture reseting procedure often mainly to the strutting of breast lumbar vertebra rear pillar, to the reset response of preceding center pillar a little less than.Be provided with the snap ring that is used for fixing dilator in Wicresoft passage skin outside on this lumbar vertebra compression fracture Minimally Invasive Surgery release link montant; When dilator struts snap ring when resetting; Surgical doctor is fixing with the release link upper end, and the effect that struts is mainly reflected on the preceding center pillar of anterior vertebral.
The effect that this utility model is useful is: this utility model is rational in infrastructure, simple; After inserting cannulated sleeve and the U-shaped groove is stuck in vertical rod, prevent rotation, and montant is provided with the snap ring design, is convenient to strut; Reached and hindered effectively strutting of the preceding center pillar of vertebra, easy and simple to handle.This utility model is simple in structure, simple operation, and application safety has been filled up the blank in the field, is worthy of popularization.

Description of reference numerals: main body 1, cross bar 1-1, montant 1-2, snap ring 2, U-shaped groove 3, in eat dishes without rice or wine 4, vertical rod 5, screw 6.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further:
With reference to accompanying drawing: this lumbar vertebra compression fracture Minimally Invasive Surgery release link; Comprise main body 1; Wherein main body 1 comprises cross bar 1-1, is fixed on the montant 1-2 on the cross bar 1-1, and wherein main body 1 is T font structure, and wherein montant 1-2 is the hollow cylinder structure; And have on the cross bar 1-1 communicate with montant 1-2 in eat dishes without rice or wine 4, wherein the lower end of montant 1-2 is provided with U-shaped groove 3.Montant 1-2 is provided with the snap ring 2 that is used for fixing dilator.
In the lumbar vertebra compression fracture Minimally Invasive Surgery, inserted the pedicle screw 6 of tape channel in the little otch, can implement this reset process this moment.Like accompanying drawing 3, insert earlier and hinder the neighbouring pedicle of vertebral arch empennage passage place of vertebra, be about to montant 1-2 and be inserted in pedicle of vertebral arch passage to U-shaped groove 3 and block on the vertical rod 5, in eat dishes without rice or wine 4 to insert nut and screwdriver.Be fixed on two statures of dilator on the snap ring 2 that is positioned at the skin outside on two release links this moment, keep the top suitably to pressurize, and U-shaped groove 3 dilators of lower end struts, and can obtain the satisfied vertebra reset effect of hindering.This utility model is simple in structure, and is easy to operate, and better reduction is worth application.
Though this utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
