The specific embodiment
As shown in Figure 1, a kind of acetabular bone antetheca associating of this utility model tetragonal body dissection armor plate, body is integrated wide shape steel plate of narrow middle part, two ends, body two ends are the first plate body 1, steel plate middle part is the second plate body 3, on the first plate body 1, be provided with sliding eye 2, the os integumentale screw 6 for fixed body and pressure bone broken line is installed on sliding eye 2; As shown in Figure 6, a side direction of the second plate body 3 has the fixed teeth 5 for fixing human tetragonal body sclerite, and the lower end of fixed teeth 5 is to the interior lateral buckling of the second plate body 3; On the second plate body 3, be provided with lock hole 4, on lock hole 4, install for the fixing bone piece of pulverizing and prevent the lock screw 9 being shifted.Fixed teeth 5 is fixedly connected with or is flexibly connected with the second plate body 3.As shown in Figure 5, the bottom of the second plate body 3 is provided with the groove 13 adapting with the upper end shape of fixed teeth 5, and groove 13 is along the width setting of the second plate body 3.
As shown in Figure 2, the both sides of groove 13 are respectively equipped with one or two fixing hole 12, and the screw for fixing fixed teeth 5 is installed on fixing hole 12.Sliding eye 2 is oval unthreaded hole, and its long axis direction is consistent with body trend.As shown in Figure 3, os integumentale screw 6 comprises os integumentale screw cap 7 and threaded os integumentale screw bar 8, the interior hexagon that os integumentale screw cap 7 is outer smooth.Lock hole 4 is for being with female circular hole, lock hole 4 side by side or W type arrange.
As shown in Figure 4, lock screw 9 comprises lock screw cap 10 and lock screw bar 11, and lock screw cap 10 outer walls are provided with the external screw thread matching with the screw thread of lock hole 4, and lock screw bar 11 is the smooth shaft of front end tip.Described body is the concavo-convex anatomical shape that is applicable to human body acetabular bone antetheca, and is titanium alloy material.Lock hole 4 on the second plate body 3 is 4,6,8 or 10, makes steel plate be divided into large, medium and small three kinds of specifications.
The end of fixed teeth 5 is the strip that can be placed in groove 13, and the number of fixed teeth 5 is 1,2 or 3; By this rectangular being placed in groove 13, then slide to the direction of tetragonal body, slide into behind suitable position, lock screw 9 is installed in lock hole 4 and is fixed.Because fixed teeth 5 is flexibly connected or is fixedly connected with the second plate body 3, in the time that fixed teeth 5 is flexibly connected with the second plate body 3, as required, body is separated to use with fixed teeth 5, the device using body as fixing acetabular bone antetheca uses.
The second plate body 3 is placed on the place of sclerite, according to the shape of fracture, adjusts the shape of steel plate, and fixed teeth 5 is positioned in groove 13, and it is moved to tetragonal body, moves to behind suitable position, and screw is installed in fixing hole 12, is fixed tooth 5; Lock screw 9 is installed in lock hole 4, the external screw thread of lock screw cap 10 matches with the screw thread in lock hole 4, lock screw 9 also plays the effect of the fixed teeth 5 that is flexibly connected with the second plate body 3 of pressurization, the thick 2mm～3mm of other local thickness of Thickness Ratio at second plate body 3 places at groove 13 places.In the time that os integumentale screw 6 is installed, os integumentale screw 6 is put into sliding eye 2 by of the outside of steel plate body, the other end adopts identical method to put into os integumentale screw 6, in actual mechanical process, os integumentale screw can slide along the direction of the major axis of sliding eye 2, plays the effect of inside pressurization.
