The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Like Fig. 1, shown in 2, the specific purpose tool that built-in 8 letter stencils are installed in the orthopaedic operation of the present invention comprises positioning needle 1, inclinometer 2,8 character matrix plates 3 of two guide hole appearance, two guide hole appearance 4,8 letter stencil clamps etc.
Be fixedly connected with the inclinometer 2 of two guide hole appearance on the guide hole post of two guide hole appearance 4, the guide hole column bottom is connected with 8 character matrix plates 3, is inserted with positioning needle 1 between the inclinometer 2 of two guide hole appearance and 8 character matrix plates 3.
Behind the operative incision on the skeleton that exposes specific part insert positioning needle 1, place Eight characters template 3 through the location pin hole on 8 character matrix plates 3, place two guide hole appearance 4 through the location pin hole on the inclinometer 2 with hue angle function; Adjust the angle of punching, through the drill guide bore punching on two guide hole appearance 4, in like manner play another boring with target drill; Take out 8 character matrix plates 3; Place 8 letter stencils, add behind the screw fasteningly, sew on operative incision with screwdriver.
Like Fig. 3, shown in 4, consider that boring the time needs stable status, 8 character matrix plates, 3 front ends are fixing with 8 letter stencil clamps 5, and 8 letter stencil clamps 5 are in that to sting when tight its head two pincers just parallel and it is apart from being the distance that 8 character matrix plates 3 are held two faces.Two convexities of its head just in time withstand on two grooves that are held on the face of 8 character matrix plates 3, have increased stability.
As shown in Figure 5, the inclinometer 2 of two guide hole appearance comprise connect fast 12, attachment screw 13; Angle pointer 14, hue angle knob 15, graduated tile 16; Rotating shaft 17 connects fast 12 front ends with the fixing graduated tile 16 of four screws, and hue angle knob 15 is fixed on the attachment screw 13 in the graduated tile 16; Angle pointer 14 is screwed on hue angle knob 15, after positioning needle 1 position is confirmed, places 8 character matrix plates 3.Can not to damage osseous tissue in order holing and to give the boring guiding, this design has utilized inclinometer 2 adjustings to make the centrage of positioning needle 1 and the centrage of boring that definite angle arranged.Angled scale on the inclinometer 2 wherein can rotate and transfers to suitable angle.
At first, by attachment screw 13, rotating shaft 17, graduated tile 16 and hue angle knob 15 are connected; Secondly, angle pointer 14 is screwed on hue angle knob 15, once more; The integral body that connects is fixed on zero pair pilot hole appearance through four screws on the graduated tile 16 connects fast 12; At last, be fixed on two pilot hole appearance 4 by inclinometer 2, fastening bolt 11 is to make inclinometer 2 be fixed on two pilot hole appearance 4 allocation really.
