In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] In the prior art, during the actual pulling process of the inner row of sutures in, since the winding path of the traction line around the pre-set knot on the outer row of anchors of the full suture is complex, the frictional resistance between the traction line and the outer row of anchors of the full suture is relatively large, and the sutures may easily strangle or cut the operator's fingers. Furthermore, when the traction line is pulled by an external force, the pre-set knot is affected by the frictional resistance, and it is easy for the suture to be tightened before the pre-set knot is introduced into the outer row of anchors of the full suture, resulting in failure of the traction operation and product scrapping.

[0051] To solve the above problems, Figure 1-Figure 5As shown, this embodiment provides a suture traction device, which is used to pull the suture 20 into the full suture anchor assembly 10. The full suture anchor assembly 10 includes an inserter 101 and a full suture outer row anchor. The full suture outer row anchor includes a nail body 102 and a traction line 103. The traction line 103 is passed through the nail body 102; the nail body 102 is installed at the implantation end of the inserter 101. Specifically, the suture traction device includes a traction box 1 and a base 2, the nail body 102 and a part of the inserter 101 are installed in the accommodating cavity of the traction box 1, the side wall of the traction box 1 is provided with two routing holes 11 for passing the traction line 103, the traction box 1 includes a detachably connected traction cover body 12 and a traction bottom shell 13, the traction cover body 12 is provided with a first winding post 121 for winding the traction line 103, and the traction bottom shell 13 is provided with a second winding post 131 for winding the traction line 103; the base 2 is detachably connected to the traction bottom shell 13, and the base 2 is provided with a plurality of limit posts 21 for winding the traction line 103, the limit posts 21 pass through the side wall of the traction bottom shell 13 and extend into the accommodating cavity, and limit posts 21 are provided on both sides of each first winding post 121.

[0052] When in use, the full suture anchor assembly 10 is installed in the traction bottom shell 13; the base 2 is connected to the traction bottom shell 13, the preset knot of the traction line 103 is wound around the limit post 21 to form a first wire loop 1031, the preset knot of the traction line 103 is wound around the second winding post 131 to form a second wire loop 1032, and the two ends of the traction line 103 are respectively passed through the two routing holes 11; the traction cover body 12 is connected to the traction bottom shell 13, and the base 2 is disassembled so that the first wire loop 1031 is wound around the first winding post 121, and one end of the wireless loop of the traction line 103 is wound around the handle 1011 of the inserter 101 to complete the assembly of the suture traction device. In this embodiment, since the preset knot of the traction line 103 is wound around the limiting post 21 to form a first wire loop 1031, after assembling the traction cover body 12, the first wire loop 1031 is wound around the first winding post 121, and the first wire loop 1031 is wound around the first winding post 121 with the assistance of the limiting post 21 on the base 2, and the preset knot of the traction line 103 is wound around the second winding post 131 to form a second wire loop 1032. In this embodiment, the first winding rod 121 and the second winding rod 131 are used for arranging the path of the traction wire 103. Before the traction wire 103 pulls the suture 20, the traction wire 103 is only passed through the nail body 102 and is not directly wound around the side wall of the nail body 102, so that when the traction wire 103 pulls the suture 20, the friction resistance between the sutures 20 at the preset knots and between the sutures 20 and the nail body 102 is greatly reduced, thereby avoiding the tightening of the preset knots during the traction process, so that the traction wire 103 can smoothly pull the suture 20 through the nail body 102, thereby greatly reducing the traction resistance and avoiding the suture 20 from cutting the operator during traction.

[0053] In this embodiment, the suture 20 is an inner row suture, and the nail body 102 is woven from textile threads using a weaving process. The nail body 102 is provided with a hole for passing the traction line 103 or the suture 20 .

[0054] In this embodiment, Figure 3-Figure 5 As shown, the traction cover 12 is provided with a plurality of buckles 124 on its circumference, and the traction bottom shell 13 is provided with a plurality of slots 137 on its circumference.

[0055] Preferably, four first lugs 125 are provided at the four corners of the traction cover 12, which are convenient for the operator to hold when opening the cover. Two second lugs 138 are provided on the outer side of the traction bottom shell 13, which are convenient for the operator to hold when opening the cover.

[0056] In the prior art, the operation of pulling sutures is performed outside the body, and the nail body of the outer row of anchors of the full suture is only clamped in the U-shaped groove at the head end of the inserter, and is not effectively fixed. If the operator causes the inserter to shake greatly during the traction operation, the outer row of anchors of the full suture may be offset relative to the inserter or even fall off, which not only causes product failure but also increases the risk of surgery.

[0057] To solve the above problems, in this embodiment, Figure 2-Figure 6 As shown, the suture traction device also includes a fastener 3, which is detachably installed in the traction bottom shell 13, the implantation end of the inserter 101 is provided with a first U-shaped groove, the nail body 102 is installed in the first U-shaped groove, the nail body 102 is perpendicular to the implantation end of the inserter 101, the fastener 3 is provided with a second U-shaped groove 31, and the opposite side walls of the second U-shaped groove 31 are provided with arc grooves 32, the implantation end of the inserter 101 is connected to the arc groove 32, and the groove bottom of the second U-shaped groove 31 blocks the opening of the first U-shaped groove. Among them, the diameter of the arc groove 32 is consistent with the diameter of the implantation end of the inserter 101, and forms an interference fit with the inserter 101, so that the nail body 102 can be fixed in the first U-shaped groove of the inserter 101, so as to prevent the nail body 102 from falling off from the inserter 101 during the process of the operator disassembling the product package to remove the inserter 101 or the operator removing the inserter 101 from the traction box 1, thereby avoiding the occurrence of product failure.
