Abstract
An internal fixation plate system for cervical vertebra repair consists of a plate(1), screws(2), 270 degrees lockpin(3). The apertures of the plate(1) fixation system are single-rowed. The gourd-shaped plate fixation(1) apertures among which one is for the purpose of screw fixation are arranged on the middle part of the plate. The other side is echelon aperture for 270 degrees lockpin(3). The cross-section of the head of the screw(2) is an incomplete sphere. The size of the head of the 270 degrees lockpin(3) should be concordant to the depth of the echelon aperture. The screw apparatus on the head of the 270 degrees lockpin(3) is often semi-sphere. A semi-sphered puncture is positioned on the cauda of the 270 degrees lockpin(3). After the insertion of the 270 degrees lockpin(3) into the echelon aperture of the plate(1) and installment of the caudal part of the 270 degrees lockpin(3), the semi-sphered aperture, the lockpin expands under pressure lest the 270 degrees lockpin(3) casts off the plate(1) or the connection between the 270 degrees lockpin(3) and plate(1) loose.
Description
Technical field
This utility model relates to a kind of steel plate internal fixation system that cervical vertebra is repaired that is used for.
Technical background
Sustain damage at cervical vertebra, in the therapeutic process of pathological changes such as degeneration and bone tumor, the cervical steel plate inner fixer is the selection of using always.This kind cervical steel plate broad that can select in the market is not suitable for Aisan.And the operation process complexity, screw implant angle is had relatively high expectations, and obviously foreign body sensation is arranged after implanting, influence surgical effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective and a kind of cervical vertebra that provides is repaired internally-fixed steel plate system.The steel plate internal fixation system that this cervical vertebra is repaired is by steel plate (1), screw (2), and 270 degree pinnings (3) are formed.Steel plate (1) locking system hole is single-row hole, steel plate (1) lockhole be shaped as Pear-Shaped, Yi Bian wherein be screw (2) fixing hole.Another side is the shoulder hole of stepping down of 270 degree pinning (3) usefulness, and the big hole depth of its shoulder hole is consistent with 270 degree pinning (3) head cap height.Screw (2) head cross section is spherical.270 degree pinning (3) head dimensions should be consistent with the shoulder hole large diameter hole degree of depth of stepping down of 270 degree pinnings (3) of steel plate (1), the winding device of 270 degree pinning (3) heads can have any shape, but this device must be able to bear the rotation torque of 270 degree pinnings (3), the afterbody of 270 degree pinnings (3) is made a call to a hemispherical-shaped aperture, works for after the assembling its afterbody spreading being performed standard.270 degree pinnings (3) are that 270 degree pinnings (3) are inserted steel plate (1) shoulder hole with the assembly method of steel plate (1), afterbody to 270 degree pinnings applies a certain amount of power then, make the spherical empty spreading of its afterbody, prevent 270 the degree pinnings (3) deviate from from steel plate (1), and, occur loosening between 270 degree pinnings (3) and the steel plate (1).This utility model is used for the steel plate internal fixation system that cervical vertebra is repaired, owing to adopt single-row screw to fix, steel plate width obviously narrows down, and has overcome the wide problem of bringing of conventional steel plates.

The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further details.As shown in Figure 1 and Figure 2, steel plate (1) locking system hole is single-row hole, steel plate (1) lockhole be shaped as Pear-Shaped, along the positional alignment of steel plate near center line.Lockhole is screw (a 2) fixing hole on one side wherein.As shown in Figure 3, Figure 4,270 degree pinning (3) head dimensions should be consistent with the degree of depth of large diameter hole in the shoulder hole of 270 degree pinnings (3) of steel plate (1), the winding device of 270 degree pinning (3) heads can have any shape, but this device must be able to bear the rotation torque of 270 degree pinnings (3), the afterbody of 270 degree pinnings (3) is made a call to a hemispherical-shaped aperture, works for after the assembling its afterbody spreading being performed standard.As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8,270 degree pinnings (3) are necessary for clockwise direction when screwing, and Fig. 5 is that 0 degree is opening, and Fig. 6 is 90 degree, and Fig. 7 is 180 degree, and Fig. 8 is that 270 degree are locking state, and must be disposable locking, can not back and forth operate.
As shown in Figure 9, assembling, 270 degree pinnings (3) are inserted steel plate (1) shoulder hole, afterbody to 270 degree pinnings applies a certain amount of power then, make the spherical pore spreading of its afterbody, prevent that 270 degree pinnings (3) from deviating from from steel plate (1), and, occur becoming flexible between 270 degree pinnings (3) and the steel plates (1).As shown in figure 10, screw (2) head cross section is incomplete sphere, and bellmouth is arranged at the head top.According to as Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, rotate 270 degree pinnings (3) screw (2) is locked.As Figure 11, Figure 12, Figure 13, shown in Figure 14 and since this product steel plate (1) can adopt be not only single-row 2 lockholes, also can be single-row a plurality of lockholes, the needs according to the designer determine fully.The profile of steel plate (1) also only is signal for example, can be other any forms.
