Detailed description of the invention
A kind of miniature sleeve pipe Kirschner wire fixation device fixing for metacarpal fracture, comprise two end band puncturing head Kirschner wires 5, miniature cannula guide 1, the miniature sleeve pipe 3 of front end zigzag hollow cylinder, first miniature cover core 2, second miniature cover core 4, described miniature cannula guide 1 is made up of handle and front end zigzag hollow cylinder guide thimble, described handle is flexibly connected with described guide thimble, described first miniature cover core 2 with described second miniature cover core 4 for tail end band emits Kirschner wire, described miniature sleeve pipe 3 is combined to form miniature sleeve pipe Kirschner wire 6 with described band puncturing head Kirschner wire 5.
Using method: after reduction of the fracture success, get the 2nd metacarpal bone oar side or the 5th metacarpal bone ulnar side micro-incision, first miniature cover core 2 is inserted in miniature cannula guide 1, blunt separation is to second ossa metacarpi radialis or the 5th metacarpal bone ulnar side, in miniature cannula guide 1, guide thimble front end sawtooth is convenient to fix point of puncture and puncture direction, in miniature cannula guide 1, the use of guide thimble prevents the fashionable damage to the 1st dorsal interossei or hypothenar muscle of miniature sleeve pipe Kirschner wire 6 rotary drilling, take out the first miniature cover core 2, insert miniature sleeve pipe Kirschner wire 6, connect electric drill, stop the rotation after saturating 2nd metacarpal bone of rotary drilling or the 5th metacarpal bone bilateral sclerotin, be separated miniature sleeve pipe Kirschner wire 6, band puncturing head Kirschner wire 5 is taken out, leave miniature sleeve pipe 3, insert in miniature sleeve pipe 3 by the second miniature cover core 4, blunt separation, to adjacent sclerotin, takes out the second miniature cover core 4, insert band puncturing head Kirschner wire 5, the saturating bilateral sclerotin of rotary drilling, stops the rotation, and the purposes of miniature sleeve pipe 3 is the damage of anti-leukorrhagia stopping puncturing head Kirschner wire 5 to metacarpal bone interosseus meat when rotating.Inserting other two miniature sleeve pipe Kirschner wires according to same method intersects fixing, and miniature sleeve pipe Kirschner wire is cut short in bending, stays outside skin, and art finishes; Utilize miniature cover core to coordinate blunt separation to sclerotin place with zigzag microguide, by under guide thimble and miniature casing protection, miniature sleeve pipe Kirschner wire and the deep matter of Kirschner wire rotary drilling, reduce the damage of direct Kirschner wire to muscle.Wherein, first miniature cover core 2 matches with miniature cannula guide 1, first miniature cover core 2 can stretch in the guide thimble of miniature cannula guide 1, first miniature cover core 2 matches with miniature sleeve pipe 3, miniature sleeve pipe Kirschner wire 6 diameter, second miniature cover core 4 is identical with band puncturing head Kirschner wire 5 diameter, and the second miniature cover core 4 can stretch in miniature sleeve pipe 3.
Band puncturing head Kirschner wire 5 is consistent with miniature sleeve pipe 3, before miniature sleeve pipe 3, laciniation is consistent with the puncturing head of band puncturing head Kirschner wire 5, form an integrated piercing head group and synthesize miniature sleeve pipe Kirschner wire 6, miniature sleeve pipe 3 is combined into miniature sleeve pipe Kirschner wire 6 with band puncturing head Kirschner wire 5 has following three kinds to combine embodiment:
