After several days, when the tissue edema is reduced and the incision tension is reduced, thesuture 3 is tightened again, and thebilateral suture 3 can be pulled, thereby completing the third step. And after tensioning, fixing the pulledsuture 3 by using a second wire holder 20-2, and cutting off theredundant suture 3 and the first wire holder 20-1 to finish the fourth step. In addition, the parts in the dashed boxes of the d-diagram and the e-diagram in fig. 10 can be optionally cut out or reserved. After the operation is repeated for a plurality of days, after the tissue edema is relieved and the incision tension is reduced, thesuture 3 is tensioned again until the incisions are closed, the pulledsuture 3 is fixed by the third second thread clamp 20-3 after tensioning, andredundant suture 3 and the second thread clamp 20-2 are cut off to finish the fifth step. And finally, after the incision is healed, starting the last step, lifting the third second wire holder 20-3, cutting off thesuture 3, pulling thefirst wire holder 10, and pulling out thesuture 3 from the other end.

According to the embodiments, the thread clamping device, the thread clamping gun and the using method of the thread clamping device provided by the invention, wherein the thread clamping device comprises the thread clamping device body and the inserting block, the thread clamping device body is provided with the clamping groove, the inserting block is clamped in the clamping groove, and the clamping of the suture is realized by the mutual matching of the protrusion and the groove between the bottom of the inserting block and the bottom surface of the clamping groove, so that the suture is prevented from sliding. When needs fixed suture, put into the draw-in groove of wire holder body with the position that the suture needs to be fixed earlier, insert the wire holder body with the inserted block again, until the bottom of inserted block and the mutual butt of bottom surface of draw-in groove, the wire holder is not hard up with suture zonulae occludens this moment. This thread clamping device simple structure, convenient to use can effectively clip the stylolite and can not become flexible, realize the inseparable centre gripping to the suture, can replace the suture to tie a knot, shorten operating time, reduce doctor's work load.

Further, operating personnel only need press the pressing mechanism of a thread clamping device rifle once, can be fast with the inseparable centre gripping of suture in the thread clamping device, need not manual knot again, and one hand can be operated, convenient to use, labour saving and time saving.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
