Description
Technical field
The present invention relates to fracture compression steel plate technical field, especially a kind of cervical spine locking compression steel plate being applied to Transoral treatment Study of Atlas Fracture by Finite.
Background technology
Articulatio atlantoepistrophica has high mobility, its stability depends primarily on the complete of ligament structure, when the pathological changes such as exogenous injury, tumor appears in atlas and axis, easily make atlanto-axial instability, subluxation, dislocation etc., numb limbs and tense tendons, muscular strength decline, cervical spine instabily, cervical pain and restriction of neck motion to cause compressing to cause to oblongata and cervical spinal, due to articulatio atlantoepistrophica complex position deeply with dissection complex structure, in surgical intervention, have challenge, Therapeutic Method in the past mainly contains Halo Vest and draws fixing, Occipital-cervical fusion, extensive region pivot fusion.Halo Vest draws fixing consuming time longer, be difficult to obtain to the satisfied and lasting reset of lateral mass of atlas, there is the situation that healing irregularity, disunion etc. need limited operation to make up, and probably make original dislocation occur fixing and then cause Progressive symmetric erythrokeratodermia cervicodynia, and although various fusion can stablize joint, but all to sacrifice joint movement function for cost, cause head and neck limitation of activity after operation in patients.
Ruf M, Xu Rongming, Hu Yong, Ma Weihu, Bransford R, Chung SK, Abeloos L etc. both at home and abroad expert have employed only to the simple internal fixation method treatment atlas unstable fracture of atlas, obtain good clinical efficacy.But, in clinical practice, be not specifically applied to the internal fixation apparatus that Transoral fixes Study of Atlas Fracture by Finite, in the clinical treatment in early stage, apply phalanges or metacarpal bone Interal fixation.There is following several drawback in it:
1, this steel plate does not have pressurizing mechanism, to such an extent as to maintenance that can not be good resets.
2, anterior arch of atlas is relatively thin, and the screw length that can hold is less, but shorter screw exists the attribute easily coming off, fix shakiness.
3, all need the anterior arch radian according to atlas during clinical practice, the steel plate that suitable bending adopts, have impact on the hardness of steel plate to a certain extent, easily causes reset, fixing undesirable.
4, screw location protrudes from surface of steel plate, support throat wall may be comparatively large, easily cause the abnormal sensory of bottleneck throat discomfort.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of structure simple, fixing-stable and accelerate the cervical spine locking compression steel plate of Study of Atlas Fracture by Finite healing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cervical spine locking compression steel plate, comprise the steel plate main body that cross section and longitudinal section are arc, thin two ends thick structure centered by described steel plate main body, steel plate main body is divided into canned paragraph and is positioned at the pressurized segment of canned paragraph both sides, described canned paragraph offer multiple screw hole connect together formed elongated hole, described elongated hole inwall is provided with screw thread; Described pressurized segment is provided with screw locking device, and described screw locking device comprises the pressurization hole in pit-holes structure, and described pressurization hole is provided with the chute in concave spherical surface near the side of elongated hole; Described elongated hole and pressurization Kong Jun are positioned on the shaft centre line of steel plate main body.Pressurization hole is pit-holes structure, screw can well be avoided to follow closely tail exposed, is not easy to cause throat wall uncomfortable.Adopt the art chute designs in concave spherical surface, to reset under direct-view, fixing stability strengthened by chute employing screw locking device, and chute can be used for observing the reset case of fracturing simultaneously, adjusts reset in time.
Further, the longitudinal section of described steel plate main body comprises excentric upper arcwall face and arc lower face, and the radius of upper arcwall face is greater than the radius in arc lower face.
Further, the aperture of screw is used to be less than the aperture using screw in pressurization hole in described elongated hole.Pressurized segment uses large aperture screw, adopts pressurization hole design concept, screw stretching resistance is strengthened, increases the stability that steel plate main body is fixed, make fracture and fixture complex more firm.The hole internal fixation screw that simultaneously pressurizes is easy to operate, and entry angle easily adjusts, and is conducive to clinical practice.Elongated hole uses the screwdriver of same model with the screw of use in pressurization hole, avoids the complexity that instrument uses to a certain extent.
Further, the center thickness of described steel plate main body is 1.5 ~ 2.3mm, and the two-end thickness of steel plate main body is 2.5 ~ 3.2mm.
Steel plate main body adopts cambered design, and cambered surface meets radian biology of anterior arch of atlas, simultaneously thin centered by steel plate main body, structure that two ends are thick; The central thickness of steel plate main body is 2mm, effectively can avoid because of narrow space between anterior arch of atlas and pharynx rear wall, easily cause uncomfortable drawback; The two-end thickness of steel plate main body is 3mm, because pressurized segment surrounding tissue gap is comparatively large, 3mm can not cause the situation of local discomfort and fixing difficulty.Utilize the thickness of 3mm to pressurize to be provided with in hole the chute in concave spherical surface, the hold of screw can be strengthened, further ensure that the laminating of fracture site, effectively avoid because of fracture involutory not good enough cause nonunion may.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, easy to operate, has following beneficial effect:
1, effectively maintain the integrity of articulatio atlantoepistrophica, atlantooccipital joint range of activity, maintain the height of atlas ring, effectively avoid the forfeiture of the pillow-extensive region-pivot function caused because of internal fixtion;
2, adopt curved plate effectively to avoid the biological property of internal fixtion caused because of pre-bending in operation to change;
3, steel plate main body two ends thickening, designs slip pressurized tank, makes the reduction of the fracture, fixes rear fracture site laminating more closely, effectively avoid the situation that the maintenance reset of clinical middle existence is in the past difficult;
4, steel plate central authorities are thinner, design lock hole, and namely the effective fixing stability realized, it also avoid screw slippage simultaneously and cause unexpected possibility;
5, the application of the technology of flooding of screw nail tail, after internal fixtion is completed, surface of steel plate still keeps smooth, effectively avoids because location protrudes from the possibility that steel plate causes throat wall foreign body sensation;
6, the elongated hole of steel plate central authorities, can meet the fixing of lock screw, is conducive to observing the reset case of fracture and the hold-down screw of adjustment locking at any time simultaneously;
7, lateral mass forcing screw fixing hole is designed to ellipse, is conducive to screw and slides in fixing hole according to individual variation situation, be convenient to adjustment direction.
