In figure, labelling is as follows: clamping handle 1, connecting rod 2, connecting hole 3, nut 4, straight-bar 5, cross bar 6, bayonet lock 7, latch 8, jack 9, extension spring 10, elastic draw bar 11, skin outside fix plate 12, notch graft hone lamella 13, skin outside fix board slot 14, notch graft hone lamella groove 15, fixing threaded hole 16.
Detailed description of the invention
Skin outside fix plate 12 or notch graft hone lamella 13 are pushed into synthetism position along the length direction of long bone by clamping handle 1 by the present invention, after arriving synthetism position, are accurately positioned fixing notch graft hone lamella 13 by skin outside fix plate 12.
Figure shows, skin outside fix plate 12 and notch graft hone lamella 13 that the present invention uses are elongated plates face, the skin outside fix board slot 14 along plate face length direction and notch graft hone lamella groove 15 is had at the two ends in plate face, have fixing threaded hole 16, fixing threaded hole 16 to be used for fixing screw on plate face between skin outside fix board slot 14 and notch graft hone lamella groove 15 long bone is fixed.Skin outside fix plate 12 is identical with notch graft hone lamella 13 shape, and skin outside fix board slot 14, notch graft hone lamella groove 15 are identical with the position of fixing threaded hole 16, in order to can accurately fix notch graft hone lamella 13 by skin outside fix plate 12 after inserting notch graft hone lamella 13.
Figure shows, the plate face of notch graft hone lamella 13 and skin outside fix plate 12 there is connecting hole 3 respectively, two connecting holes 3 are identical and the most relative with the position on the plate face of skin outside fix plate 12 at notch graft hone lamella 13, the two ends of connecting rod 2 are connected with two connecting holes 3 respectively, notch graft hone lamella 13 and the centrage of the length direction of skin outside fix plate 12 after connecting hole 3 connects are parallel in same vertical plane so that the fixing threaded hole 16 of skin outside fix plate 12 and notch graft hone lamella 13 can be the most relative.
Showing in figure, in order to reach notch graft hone lamella 13 and skin outside fix plate 12 accurate contraposition, connecting rod 2 and connecting hole 3 use following two structure:
The first structure is, connecting hole 3 on the plate face of notch graft hone lamella 13 and skin outside fix plate 12 is respectively screw, there is screw thread at the two ends of connecting rod 2, the lower end of connecting rod 2 is tightened in the connecting hole 3 of notch graft hone lamella 13, the screw of the upper end then connecting hole 3 on the plate face of skin outside fix plate 12 being enclosed within connecting rod 2 rotates, after to the upper end of connecting rod 2 through the plate face of skin outside fix plate 12, adjust skin outside fix plate 12 the most relative with notch graft hone lamella 13, by the screw threads for fastening of nut 4 with connecting rod 2 upper end.
The second structure is, the cross section of the connecting hole 3 on the plate face of notch graft hone lamella 13 and skin outside fix plate 12 is respectively the regular polygon of rule, connecting rod 2 two ends are the polygon body of rod, the cross section of the polygon body of rod matches with the regular polygon in the cross section of connecting hole 3, the polygon body of rod at connecting rod 2 two ends is respectively inserted in the connecting hole 3 on the plate face of notch graft hone lamella 13 and skin outside fix plate 12, and the polygon body of rod at connecting rod 2 two ends and connecting hole 3 are for be slidably matched closely.Notch graft hone lamella 13 and skin outside fix plate 12 are carried out accurate contraposition by the connecting hole 3 of regular polygon with connecting rod 2 by this structure, and regular polygon can be triangle, tetragon, pentagon or hexagon.
Figure shows, the clamping handle 1 of the present invention is made up of two parallel straight-bars 5 and a cross bar 6, the rear end of two straight-bars 5 is connected with cross bar 6 two ends, the front end of two straight-bars 5 has two kinds of clamp structures respectively, and skin outside fix plate 12 or notch graft hone lamella 13 are pushed into synthetism position along the length direction of long bone by two kinds of clamp structures.
A kind of structure is that the front end of two straight-bars 5 has multiple horizontal bayonet lock 7 respectively, and multiple bayonet locks 7 are arranged in parallel along the length direction of straight-bar 5, and the both sides of the edge of skin outside fix plate 12 are respectively embedded in the gap of adjacent two bayonet locks 7.
Another kind of structure is, the front end of two straight-bars 5 has horizontal latch 8 respectively, multiple horizontal jack 9 is had on the two sides of notch graft hone lamella 13, multiple jacks 9 arrange along the length direction of notch graft hone lamella 13, and the latch 8 of two straight-bar 5 front ends is inserted respectively in the jack 9 of notch graft hone lamella 13 both sides.
Showing in figure, in order to clamp convenient and prevent from disengaging, connecting between the rear portion of the parallel straight-bar 5 of pinch handle 1 two has extension spring 10 or elastic draw bar 11, and the two ends of extension spring 10 or elastic draw bar 11 are connected with two straight-bars 5 respectively.Extension spring 10 relies on the elastic force of self to strain two straight-bars 5 to centre, and elastic draw bar 11 can only be held cross bar 6 by operator one, and finger upwards strains elastic draw bar 11 simultaneously, makes two straight-bars 5 draw close to centre, clamping skin outside fix plate 12 or notch graft hone lamella 13.
The use process of the present invention is as follows:
The two ends of connecting rod 2 are connected with the connecting hole 3 on the plate face of notch graft hone lamella 13 and skin outside fix plate 12 respectively, use threaded or regular polygon hole connection, notch graft hone lamella 13 after connection and the centrage of the length direction of skin outside fix plate 12 are parallel in same vertical plane so that the fixing threaded hole 15 of skin outside fix plate 12 and notch graft hone lamella 13 can be the most relative.
Skin outside fix plate 12 or notch graft hone lamella 13 is clamped by the bayonet lock 7 or latch 8 pinching handle 1 front end, hold and pinch handle 1 notch graft hone lamella 13 is pushed into synthetism position along the length direction of long bone, after arriving synthetism position, implanted downwards fixing screw by the skin outside fix board slot 14 of skin outside fix plate 12, be accurately positioned fixing notch graft hone lamella 13.
