Detailed description of the invention

Below in conjunction with concrete accompanying drawing, the invention will be further described。

As it is shown in figure 1, the described fixing drag hook of a kind of multi-joint, including band joint drag hook blade 1, fixing galianconism 2, long regulating arm 3 and band joint fixation apparatus 4。The described lower end with joint drag hook blade 1 arranges drag hook blade 11, and upper end arranges semiarthrosis 1。The head end of described fixing galianconism 2 arranges semiarthrosis 2 21, and tail end arranges semiarthrosis 3 22。The head end of described long regulating arm 3 arranges semiarthrosis 4 31, and tail end arranges semiarthrosis 5 32。The described head end with joint fixation apparatus 4 arranges semiarthrosis 6 41, and tail end is arranged to and fixes the inserted link fixed mechanism 6 that inserted link is fixed temporarily。Described semiarthrosis 1 and semiarthrosis 2 21, semiarthrosis 3 22 and semiarthrosis 4 31, semiarthrosis 5 32 and semiarthrosis 6 41 mate respectively and inlay connection, respectively connect semiarthrosis energy translation-angle and do not deviate from。Each joint is respectively equipped with arthrodesis mechanism 5, each joint position can be made temporarily fixing or get loose。Described long regulating arm 3 includes that groove regulates half arm 33, inserted link regulates half arm 34 and slide bar fixed mechanism 35, and inserted link regulates half arm 34 and can be embedded in groove and regulate in half arm 33 and along the length of regulating arm 3 long described in major axis slidable adjustment。Groove can be made to regulate half arm 33 for adjustment slide bar fixed mechanism 35 and inserted link regulates half arm 34 position and fixes temporarily or get loose。

During use, being inserted by the drag hook blade 11 with joint drag hook blade 1 of most for fixing for described multi-joint drag hook head end needs tractive to expose operative incision side, it is temporarily fixed on operation table inserted link by the caudal end inserted link fixed mechanism 6 with joint fixation apparatus 4, regulate half arm 33 by the groove of long regulating arm 3 and inserted link regulates half arm 34 length to the fixing drag hook of multi-joint and is adjusted, by the joint that the head end semiarthrosis 2 21 of the semiarthrosis 1 with joint drag hook blade 1 and fixing galianconism 2 is formed, the angle of the fixing drag hook of multi-joint is adjusted by three joints that the joint of the tail end semiarthrosis 3 22 of fixing galianconism 2 and head end semiarthrosis 4 31 formation of long regulating arm 3 and the tail end semiarthrosis 5 32 of long regulating arm 3 and the head end semiarthrosis 6 41 with joint fixation apparatus 4 are formed, operative incision is made to be pulled and fully rear exposure, then regulate each arthrodesis mechanism 5 to make each joint position be fixed and regulate slide bar fixed mechanism 35 to make the length of the fixing drag hook of multi-joint be fixed, now, the fixing drag hook of multi-joint has been fixed, without surgical doctor effort operation。

Different profile can be become according to difference Demand Design of performing the operation for reaching different operation application target, the size length width of drag hook blade 11 and crooked radian。The composition movable joint of each semiarthrosis is current common structure, do not specifically describe, it is necessary to explanation is in every pair of paired semiarthrosis, and one of them is cotyla herein, corresponding another one is the ball and socket joint of coupling, and concrete tandem is to result of use zero difference。

As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 5, described arthrodesis mechanism 5 includes the joint threaded hole 51 running through cotyla and the joint bolt 52 mated with joint threaded hole 51。When joint position is fixed by needs temporarily, joint bolt 52 is entered to joint threaded hole 51 inward turning, along with the screw-in of joint bolt 52, the top of joint bolt 52 holds gradually on the ball and socket joint surface being positioned at cotyla, so that the position of cotyla and ball and socket joint is fixed；When needing to adjust joint position, again fixing after reverse operating。Certainly, the mode of arthrodesis is a lot, no longer illustrates one by one herein。

As shown in Figures 5 and 6, described slide bar fixed mechanism 35 includes the slide bar threaded hole 351 that through-going recess regulates half arm and the slide bar bolt 352 mated with slide bar threaded hole 351。When need groove is regulated half arm 33 and inserted link regulate the position of half arm 34 fix temporarily time, slide bar bolt 352 is screwed in slide bar threaded hole 351, screw-in along with slide bar bolt 352, the top of slide bar bolt 352 holds the surface regulating half arm 34 at the inserted link being positioned at groove and regulating half arm 33 intracavity gradually, so that groove regulates half arm 33 and inserted link regulates the position of half arm 34 and fixes temporarily；When needing the length adjusting long regulating arm 3, again fixing after reverse operating。Certain groove regulates half arm 33 and inserted link to regulate the fixed form of half arm 34 a lot, be an embodiment herein。

As it is shown in fig. 7, described inserted link fixed mechanism 6 includes being arranged on the hook 42 with joint fixation apparatus 4 tail end, is arranged on the hook bolt fixing hole 43 of 42 top projections, threaded adjusting bar hook 60 and hook adjusting nut 63。Described threaded adjusting bar is linked up with 60 tail ends and is arranged the reversely hook 61 relative with hook 42, threaded adjusting bar is linked up with 60 head ends and is arranged the external diameter threaded adjusting bar 62 less than bolt fixing hole 43 internal diameter, and threaded adjusting bar 62 can be nested with in bolt fixing hole 43 and slide along major axis。Described threaded adjusting bar 62 outer surface arranges, with hook adjusting nut 63 inner surface, the screw thread mated, and hook adjusting nut 63 can threadingly move by adjusting rod 62 outer surface spiral。Described hook adjusting nut 63 external diameter is more than the internal diameter of bolt fixing hole 43。

In enforcement, the length of threaded adjusting bar 62 is more than the length of bolt fixing hole 43, the threaded adjusting bar 62 of described threaded adjusting bar hook 60 is nested with in the bolt fixing hole 43 of hook 42 top projections, and described hook adjusting nut 63 is closely nested with the afterbody at the threaded adjusting bar 62 exposing bolt fixing hole 43。Simultaneously, it is arranged on the hook 42 with joint fixation apparatus 4 tail end and is arranged on threaded adjusting bar and links up with reversely hook 61 coupling of 60 tail ends and use, in opposite direction, the inserted link of operation bedside can be formed and clasp fixed effect, for increasing fixed effect further, lines can be set at hook 42 and reverse hook 61 apparent surfaces, increase the sassafras coefficient that rubs。When fixing for described multi-joint drag hook is fixed on inserted link by needs, unclamp hook adjusting nut 63 make hook 42 and reversely hook 61 opening magnifies, inserted link is inserted the hook 42 forming state of encircling and reversely in hook 61 armfuls bosom。Rotary hanging hook adjusting nut 63 makes hook adjusting nut 63 threadingly adjusting rod 62 move to reversely hook 61, because hook adjusting nut 63 external diameter is more than bolt fixing hole 43 internal diameter, under opposition, reversely hook 61 is drawn close gradually to hook 42, the inserted link formation of operation bedside is clasped, tighten up gradually, finally fix。

In a word, this utility model is applied at surgical operation, can be temporarily fixed at by the drag hook blade 11 of duty simply and easily on operation bedside inserted link, alleviate doctor's workload, simple in construction, and easy to use, effect is safe and reliable。
