The tendon broken ends of fractured bone, by hold clamp clamping the heel string broken ends of fractured bone, make the first inner arm 120 and the second inner arm 130 be inserted into respectively heel string two sides with
Between tendon and stndon sheath, at this point, the first outer arm 111 and the second outer arm 112 are located on the outside of skin, by rotation roller 160, make first
Inner arm 120 and the second inner arm 130 clamp heel string；
2) threading needle 300 with suture is penetrated from some guide pinhole 1111 of 110 side of bracket, and successively passes through first
Avoid holes 121, the second avoid holes 131 and third avoid holes 1121, until be pierced by from the other side of bracket 110, suture at this time
Both ends are exposed at the two sides of bracket；
3) other guide pinholes 1111 are chosen, the operation of step 2) is repeated, with complete proximal end with tenosuture；
4) by rotation roller 160, the first inner arm 120 and the second inner arm 130 is made to unclamp heel string, and exits the first inner arm
120 and second inner arm 130, the interlude of suture is pulled out by the first inner arm 120 and the second inner arm 130 from notch at this time, also,
The both ends of suture are still exposed at the two sides of bracket；
5) equally the interlude of suture is drawn from notch after suture to the method suture heel string distal end described in 4) with step 1)
Out；
6) suture is tensed, proximally and distally knotting will be corresponded to by suture, and complete finally with tenosuture.
In above-mentioned steps 3) in, according to the selection of guide pinhole 1111, it can be achieved that the suture side of parallel threading or intersection threading
Method, wherein the sewing method threaded in parallel is to choose to be denoted as 1,3 and 6 guide pinhole 1111 and penetrate suture, this is denoted as 2,4,
5 and 7 guide pinhole 1111 is optionally to penetrate suture.The sewing method for intersecting threading is to choose to be denoted as 1,2,4,5 and 7
Guide pinhole 1111 penetrates suture, and the guide pinhole 111 for being denoted as a or b penetrates seal wire, pulls out guider later, by suture from notch
It pulls out, is then exposed at the suture both ends on the outside of skin in the guide pinhole 111 for being denoted as 2 and respectively penetrates and be denoted as the guide pin of a or b
In hole 1111, finally silk-guiding strip suture is intersected and is pulled out, to complete to intersect threading.
The above method is suitable for the higher case in heel string broken ends of fractured bone position, and when case lower for heel string broken ends of fractured bone position,
Above-mentioned steps 1 can be used in it) heel string proximal end is sutured to the method described in 4), heel string distal end can be used curved threading apparatus and realize seam
It closes, specifically, after two o'clock is cut at the stop of heel string distal end, penetrates curved threading apparatus, with reference to Figure 13, nearly by threading apparatus inner guide wire
Suture is held to pull out, holdfast is fixed, whole to suture without knot.In addition, not cutting suture for the heel string broken ends of fractured bone, above-mentioned steps can be used
1) to the method suture heel string proximal end or open suture heel string proximal end described in 4), heel string distal end uses the progress of direct puncture line device
Holdfast is fixed, with reference to Figure 14.
Embodiment described above is merely to illustrate the technical idea and feature of the utility model, and its object is to make ability
Technical staff in domain can understand the content of the utility model and implement accordingly, cannot be only practical to limit with the present embodiment
Novel patent model, which uses, to be enclosed, i.e., all according to same changes or modifications made by the revealed spirit of the utility model, still falls in this
In the scope of the patents of utility model.
