The specific embodiment

Among Fig. 1 a, 10 is first preferred embodiment of an orthopaedic sliding channel bar exterior fixing device, 11 is a right rail bar, chute 111 with an elongated opening, 12 is a left chute bar, the chute 121,13 that equally also has an elongated opening is one or the plurality of fixed structure, 14 be one can with should left side chute bar 12, the connector that is connected of right rail bar 11.

Among Fig. 1 b, 20 is one second preferred embodiment of this orthopaedic sliding channel bar exterior fixing device, 21 is a T shape right rail bar, microscler chute 211 (transverse opening) and 212 (longitudinal openings) with two vertical connections and connection, in these transverse opening chute 211 sides, then be provided with a holddown groove 213,22 is T shape left side chute bar, microscler chute 221 (transverse opening) that also has two vertical connections and be connected and 222 (longitudinal openings), and has a holddown groove 223 too in these transverse opening chute 221 sides, 23 is one or the plurality of fixed structure, 24 is one can be with should left side T shape chute bar 22 and the connector that is connected of this right side T shape chute bar 21, and 31 then is one or a plurality of nail that uses for matching with this orthopaedic sliding channel bar exterior fixing device 10 or 20 in fact.

Among Fig. 2 two figure, respectively the definition of this component Name is with respectively this assembly label is all identical with aforementioned icon; Among this Fig. 2 a, these fixed structures 13 all include a fixture 131 and a nut 132,131 of this fixtures have an integrally formed fixed part 133 and a screw division 134, this fixed part 133 is provided with a perforation can make these nails 31 pass in fact, and the substantial size of this fixture 131 (containing screw division 134) is for just passing this chute bar 11,12 chute 111,121, but front end (fixed part 133) can withstand these chutes 111 again, 121, make this fixture 131 be unlikely and can come off, 132 on this nut can be screwed with the screw division 134 of this fixture 131 in fact; These fixed structures 13 substantially with these right rail bars 11, when left side chute bar 12 combines, be that first screw division 134 with this fixture 131 passes these chutes 111,121, again with these nut 132 temporary transient spirals on this screw division 134, make these fixed structures 13 and these right rail bars 11, left side chute bar 12 movable combining, and can adjust the relative distance in twos of these fixed structures 13, behind the position of these fixed structures 13 to be determined, again these nuts 132 are closely screwed togather with this screw division 134, and make these fixed structures 13 and these right rail bars 11 in the mode of clamping, left side chute bar 12 combines really.

The component Name definition of Fig. 2 b is identical with Fig. 1 b with reference numbers, its configuration state and compound mode then be with Fig. 2 a roughly the same; The stator 230 of these fixed structures 23 is worn earlier and is sandwiched these T shape chute bars 21,22 holddown groove 213, in 223, this fixture 231 penetrates/crosses these T shape chute bars 21 again, 22 horizontal microscler chute 211,221 and the perforation of this stator 230 in, and these nails 31 are again by microscler chute 212 longitudinally, penetrate in 222, and pass the perforation 233 of these fixtures 231, and in nail implantation one or a plurality of skeleton, this nut 232 is screwed together on this screw division 234 more at last, makes these nails 31, fixed structure 23, T shape chute bar 21 or 22 and these skeletons combine in fact; And in shown in above-mentioned each figure, promptly existing effect of orthopaedic sliding channel bar exterior fixing device of the present invention improved the shortcoming that traditional external fixer all has default fixed position, and before this fixed structure 23 is closely unfixing, this fixture 231 can be subjected to this stator 230 perforation and the restrictions of these stator 230 clampings in these holddown grooves 213,223, can not drop easily.

Among Fig. 3,40 is to treat the fixed position so that the patient bone (is example with proficiency carpal bone bone) of treatment, when performing the operation in fact, the doctor can be earlier with one or a plurality of nail 31, nail is implanted (can be fully according to the actual medical needs in this wrist skeleton 40 for the treatment of the fixed position, must not consider whether to have predeterminated position), the fixed structure 13 that is inserted in this orthopaedic sliding channel bar exterior fixing device 10 then is on these nails 31, and with these fixed structures 13 in these right rail bars 11, the chute 111 of left side chute bar 12, in 121, be adjusted to optimal position or relative distance, and again these fixed structures 13 are screwed togather closely, adjust and screw tight this connector 14 at last again, can make this orthopaedic sliding channel bar exterior fixing device 10, these nails 31 and this wrist skeleton 40 all can obtain optimal fixing, and this injured wrist skeleton 40 can obtain the fine motion function that this orthopaedic sliding channel bar exterior fixing device 10 is possessed again, promotes the regeneration autotherapy of this skeleton.
