The specific embodiment
As shown in Figure 1, be the structural representation of hollow nail guider for femur neck of the present utility model, as seen from the figure, hollow nail guider for femur neck of the present utility model comprises: the guidance set with guide rod 1 and indicating arm; The sleeve assembly with the slide block 2 being slidably connected with guide rod 1; Be installed on slide block 2 for by the locked locking member 8 on guide rod 1 of slide block 2; Wherein, on slide block 2, be provided for respectively guiding a plurality of pilot holes of hollow nail placing direction, for settling the through hole 10 of guide rod 1 and for settling the locking hole 9 of locking member 8; Wherein, the axis of a plurality of pilot holes is parallel with the axis of indicating arm 4; Wherein, locking hole 9 is connected with through hole 10.
Hollow nail guider for femur neck of the present utility model has indicating arm 4, and this indicating arm front end has wedge angle, can through hip joint the place ahead, paste bone edge and neck of femur direction and squeezes into and be fixed on femoral head leading edge sclerotin, thereby play preliminary indicative function; And by locking member 8 is set, can slide block 2 is locked on guide rod 1, thus can guarantee that the distance between slide block and the indicating arm of guidance set is constant; A plurality of pilot holes are set on slide block, can work as by after indicating arm Primary Location, the steinman pin of inserting by pilot hole again can accurately complete the effect of guide-localization, thereby guaranteed the position of the hollow nail of inserting by steinman pin, make hollow nail accurate positioning, when improving that steinman pin is disposable and inserting success rate, also improved the success rate that hollow nail is inserted, thereby reduce patient suffering, save treatment time.
Concrete, as shown in Figure 1, guidance set has indicating arm 4 and the guide rod 1 being connected with indicating arm end, and indicating arm front end has wedge angle.This indicating arm 4 can be cylinder, can be also cylinder, and the axis of indicating arm 4 and the axis of pilot hole parallel.Wherein, indicating arm is fixedly connected with guide rod, can both be connected as one by dismountable connected mode, as adopted the mode being threaded; Also can adopt non-removable connected mode that both are connected as one, as adopted the mode of welding.
Wherein, as shown in Figure 1, Figure 2, Figure 3 shows, slide block 2 of the present utility model is cuboid, on it, be provided with run through its left and right both ends of the surface through hole 10, run through a plurality of pilot holes of its rear and front end face and be opened in lower surface or upper surface and be communicated with through hole 10 for settling the locking hole 9 of locking member 8.
Wherein, locking member 8 is lock-screw, and corresponding, the locking hole being opened on slide block is screwed hole, and lock-screw is arranged in screwed hole, and its one end exposes to slide block.By turning lock-screw, can make its other end be against on guide rod, thereby make guide rod and slide block in locking state; Or, by turning screw, make its other end away from guide rod, thus can make slide block along direction shown in arrow in Fig. 1 move to increase and indicating arm between distance, or along rightabout shown in arrow move to dwindle and indicating arm between distance.Wherein, the axis of lock-screw can be vertical with the axis of guide rod 1, also can have certain angle.
Wherein, the aperture of through hole is slightly larger than the external diameter of guide rod, thereby when guide rod is when the through hole, guide rod and slide block under external force can relative slidings; And the aperture of pilot hole is suitable with the external diameter of steinman pin, thereby make steinman pin can pass pilot hole, realize location smoothly, and the axis of pilot hole and the axis of through hole vertical; Locking hole and locking member 8 match, can slide block is locked at guide rod 1 through the locking member of locking hole thereby can make, and make both can not produce relative motion.
Wherein, the quantity of a plurality of pilot holes is three, comprises that the first pilot hole 3, the second pilot hole 5,6, three pilot holes of the 3rd pilot hole run through respectively the rear and front end face (as shown in Figure 1 and Figure 2) of slide block 2, and be arranged in del on slide block lower surface.
Wherein, as shown in Figure 3, between the axis of three pilot holes and the front end face of slide block, have certain angle, preferred, this angle is 135 °.
Wherein, sleeve assembly except slide block 2, also comprise be connected with slide block 2 lower surfaces for controlling the handle 7 of slide block 2, and the centrage of handle 7 is parallel to the axis of indicating arm.
It should be noted that, the noun of locality of the front, rear, left and right of indication herein, all corresponding to each member of guider at the relative position shown in Fig. 1, the end face of being seen when slide block is watched in beholder front in " slip front face " corresponding diagram 1, " rear end face " is the end face relative with " front end face "; " left side ", corresponding to the left direction of the slide block shown in Fig. 1, " right side " is corresponding to the right direction of the slide block shown in Fig. 1.
When intertrochanteric fracture of the femur or fracture of femoral neck need to reset and adopt hollow nail fixedly, by hollow nail guider of the present utility model, can grasp the direction of front and back, axle position, along three pilot holes, squeeze into steinman pin, guarantee the steinman pin of squeezing into do not understand before and after deflection, thereby make the hollow nail position squeezed into by steinman pin accurate, disposable to insert success rate high.
Although above this utility model is explained in detail; but be not limited to this; the interior perhaps principle that those skilled in the art can record according to this utility model is modified; therefore the various modifications that, all interior perhaps principles of recording according to this utility model are carried out all should be understood to include in protection domain of the present utility model.
