Description
Technical field
The present invention relates to a kind of surgical instruments, specifically a kind of posterior cervical lateral mass screw fixed guider and screw fixing means.
Background technology
Clinically at present, for the cervical diseases of patient, often need to do posterior cervical titanium rete art.In operation, be keep cervical vertebra stable, usually posterior cervical lateral mass first will be fixed with steel plate, and the screw of fixation steel plate walking in posterior cervical lateral mass is tightened angle and had strict demand.The physiological structure of posterior cervical is as shown in Fig. 1 (a), and the fixed angle of screw in posterior cervical lateral mass, from the entry point place on the lateral mass of both sides, should to the outside deflection 30 ° of cervical vertebra, as shown in Fig. 1 (b), cephalad top deflection 20 ° again, as shown in Fig. 1 (c).The angle of only having screw to be screwed into keeps correct, just can reach not only fixation, but also not damage the object of vertebra nervus lateralis and blood vessel.And in current operative process, screw is screwed into the control in direction, rely on the experience of patient and feel to carry out completely, even if before screw is screwed into, by protractor etc., the fixed angle of screw is gesticulated accurate again, because the screw thread on shank of screw is the structure of coiled coil, instead of balance and symmetry structure, so when being exerted oneself rotating screw by screwdriver, the phenomenon that screw wanders off also is unavoidable.Like this, one is the degree that screw generally can not reach fixation; Two is have other screw injures patient vertebra nervus lateralis or blood vessel because deviation angle is excessive, thus causes comparatively serious malpractice.Therefore, to be objective, the operation risk of posterior cervical titanium rete art is clinically still larger at present.
Summary of the invention
An object of the present invention is just to provide a kind of posterior cervical lateral mass screw fixed guider, is screwed into solve screw the problem that direction can not accurately control.
Two of object of the present invention is just to provide a kind of posterior cervical lateral mass screw fixing means, to improve the accuracy of screw fixed angle, reduces the operation risk of posterior cervical titanium rete art.
An object of the present invention is achieved in that a kind of posterior cervical lateral mass screw fixed guider, comprises left guider and right guider, and described left guider and described right guider are bilateral symmetry;
Described left guider is that the plate Middle face being the square location-plate of 1.18-1.22cm a length of side has a direction, the lower right corner, front from the described location-plate rearwardly oblique through hole passed in direction, the upper left corner, and the angle between the axial line of described through hole and the projection line of this axial line on described location-plate is 20 °; The lower left corner at the described location-plate back side and the plate face in the upper right corner are respectively equipped with the locating pin of rearward stretching out.
The front and back symmetrical centre point of described through hole is positioned on the plate face central point of described location-plate.
The thickness of described location-plate is 1.48-1.52mm, and the aperture of described through hole is 1.0-1.3mm, and the extension elongation of described locating pin is 3.8-4.1mm.
In location-plate on screw fixed guider of the present invention and posterior cervical lateral mass, the shape at smooth place is substantially suitable with area, when with the evagination justified margin of lateral mass on the left of hand-held left guider and posterior cervical and when location-plate is fixed in posterior cervical lateral mass by locating pin, the direction of the through hole on location-plate be just exactly left screw be correctly screwed into direction.Right guider is complied with in like manner symmetry and is fixed on the lateral mass on the right side of posterior cervical, and the direction that is correctly screwed into of right screw also just determines thereupon.The locate mode of screw fixed guider of the present invention is simple, convenient, fast, accurate, and provides into brill benchmark for follow-up drilling operation, ensure that accurate control screw being screwed into direction thus.
Two of object of the present invention is achieved in that a kind of posterior cervical lateral mass screw fixing means, comprises the following steps:
A, by the evagination justified margin of lateral mass on the left of the left side of the location-plate of left guider and edge, bottom surface and posterior cervical, location-plate is made to hide the end face of lateral mass on the left of posterior cervical;
The location-plate plate face of b, the left guider of hammering, hammers in the sclerotin of posterior cervical lateral mass by the locating pin on location-plate;
C, to insert a diameter along the through hole on left guider location-plate be that after the drill bit of 0.8-0.9mm, in the sclerotin of posterior cervical lateral mass, carry out drilling operation, drilling depth is no more than 3mm;
D, repetition step a-c, get out right side bone hole in the sclerotin with right guider lateral mass on the right side of posterior cervical;
E, unload bottom left guider and right guider, posterior cervical lateral mass attaches fixation steel plate, the fixing hole at described fixation steel plate two ends aligns with the aperture of left side bone hole and right side bone hole respectively, be screwed into respectively in left side bone hole and right side bone hole, tighten screw, can be fixed described fixation steel plate.
Screw fixing means of the present invention by guider determine drill bit enter to bore direction, adopt and first hole, then the operating procedure of screw is screwed into, change original mode of operation of directly twisting screw fixation steel plate by rule of thumb, overcome the screw problem that direction can not accurately control when being screwed into posterior cervical lateral mass, effectively can avoid the generation of screw deflection angle phenomenon voluntarily when being screwed into, ensure that screw is screwed into the correct of direction, meet the requirement of standardized surgery, both ensure that screw fixation, nerve and the blood vessel of patients with cervical both sides can not be injured again, thus substantially increase the safety of posterior cervical lateral mass fixation, reduce the operation risk of posterior cervical titanium rete art.
