Detailed Description
The technical solution of the present invention will be described in detail by the following specific examples.
As shown in fig. 1 to 5, the universal repositor for long and thin bones comprises a proximal sleeve 2, a distal sleeve 3, a distal connecting rod 4 and a vertical connecting rod 5, wherein the proximal sleeve 2 and the distal sleeve 3 are of L-shaped structures. The proximal hub 2 comprises a cross bar 21 for vertical attachment of the vertical connecting rod 5 and a proximal guide cylinder 22 for mounting the proximal k-wire. One end of the far-end connecting rod 4 is vertically connected with the vertical connecting rod 5, the other end of the far-end connecting rod is provided with the far-end sleeve 3, the far-end sleeve 3 comprises a vertical rod 31 connected onto the far-end connecting rod and a far-end guide cylinder 32 used for installing a far-end Kirschner wire, and the distance between the upper cross rod 21 of the vertical connecting rod 5 and the far-end connecting rod 4 is adjustable.
As an optimal technical scheme of the utility model, set up the first through-hole 20 that supplies vertical connecting rod 5 to pass on the horizontal pole 21 of near-end sleeve 2, the tight bolt in top is installed to one side of first through-hole 20.
