Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Assembling split-type as shown in Figure 1 to Figure 3 is planted bone and is held tamper, comprise can be assembled in together nut 1, concave surface compacting 2, plane compacting 3, convex surface compacting 4, nut 1 one end is provided with outside screw;
The equal inner hollow in one end of concave surface compacting 2, plane compacting 3 and convex surface compacting 4, and inwall is equipped with internal thread, outer wall all offers the vision slit 5 of kidney ellipsoid, this is conducive to observing the compacting nearly externally threaded end face of head rest is concave surface, plane or convex surface, is convenient to the bone block for different shapes and carries out selecting and combine compacting head;
The other end of concave surface compacting 2, plane compacting 3 and convex surface compacting 4 is solid, and outer wall is equipped with outside screw;
Concave surface compacting 2 is concave near externally threaded end face, and central position is offered for the through hole 6 through kirschner pin 7; Plane compacting 3 is planeform near externally threaded end face, and central position is offered for the through hole 6 through kirschner pin 7; Convex surface compacting 4 is convex shape near externally threaded end face, and central position is offered for the through hole 6 through kirschner pin 7;
Nut 1 central position is also offered for the through hole 6 through kirschner pin 7;
The present embodiment kirschner pin 7 diameter is 1��4mm.
The present embodiment for bone block external surface shape be concave surface, therefore the order of combination is selected to be: the outside screw of nut 1 connects the internal thread of concave surface compacting 2, the outside screw of concave surface compacting 2 connects the internal thread of plane compacting 3, and the outside screw of plane compacting 3 connects the internal thread of convex surface compacting 4.
As shown in Figure 6, concave surface compacting 2, plane compacting 3 and convex surface compacting 4 are provided with for anti-skidding groove, convex point or concave point near externally threaded end face.
If Fig. 4-1 and 4-2 is the bone grafting operation process of the present embodiment: first kirschner pin 7 bores into bone block 8 to be transplanted, then the bone of planting that kirschner pin 7 has been inserted in assembling by through hole 6 is held tamper, the length of kirschner pin is no more than and plants the length that bone holds tamper in principle, then knock, by knocking hammer 9, the nut 1 that assembling split-type plants bone holding tamper, and then bone block 8 is tamped into Cranial defect place.
As shown in Figure 5, having the bone block of three kinds of different shapeies, the first is bone block external surface shape is concave surface, and at this moment selecting assembling split-type to plant, bone holds that tamper end contacts with bone block is that convex surface tamps 4; 2nd kind is bone block external surface shape is convex surface, and at this moment selecting assembling split-type to plant, bone holds that tamper end contacts with bone block is that concave surface tamps 2; The third is bone block external surface shape is plane, at this moment selecting assembling split-type to plant, bone holds that tamper end contacts with bone block is that plane tamps 3, slippage can not be there is when hitting and beat like this in whole bone process of planting, can be interconnected again between compacting head, change at any time, length arbitrarily regulates, very convenient.
