Problems solved by technology

This knotting mode, if will increase the fixing strength by increasing the diameter of knotting and just needs to increase the length or the diameter of soft anchor implant, this just means needs to increase the diameter or the length of predrilling operation hole, has increased to human body damage

Embodiment 1

[0044] Example 1: figure 1 is the threading method of the flexible anchor, and the diameter R of the flexible anchor after the knot is clearly required before threading the thread (see figure 2 ) and the diameter R of the cylindrical flexible anchor 0. With the columnar flexible anchor taking the central axis as the center line, the outer diameter of the flexible anchor is positioned as a 360° linear point in the clockwise direction, and the connecting line between the two endpoints of 205 is the 0° point on the outer diameter of 101, and the length of 205 is ( R-R 0 ) and parallel to the length direction of 101, 205 is as close to one end of 101 as possible. 201 and 202 first start from the two ends of 205 and pass through the inside of 101 respectively, 201 and 202 start to penetrate from the 0° point, pass through from the inside of 101, pass out at the 180° point, and then turn right to the 90° point to penetrate, Pass through from the inside of 101, pass through at a...

Embodiment 2

[0045] Example 2: image 3 It is a schematic diagram of a knotted medical suture loaded into the inserter. The implantation of the knotted medical suture needs to be realized with the help of an inserter. Using the principle similar to the plunger of a syringe, the flexible anchor 101 of the knotted medical suture is inserted into the metal hollow rod 103. Then insert the metal hollow rod 104 whose inner diameter is smaller than the diameter of the flexible anchor 101, put the flexible anchor 101 on the head of 103, the two ends of the load suture all extend from the tail of the metal hollow rod 104, and assemble into a knotted medical Suture device.

Embodiment 3

[0046] Example 3: Figure 4 It is a schematic diagram of the implantation of a knotted medical suture device. To use a knotted medical suture device in a surgical operation, it is first necessary to insert the knotted medical suture device into the operation hole, and then the metal hollow rod 103 moves back, and the metal hollow rod 104 does not move , implant the flexible anchor 101 into the operation hole, then pull the load-bearing suture to extend out of the two ends of the hollow rod (thread one and thread two), the flexible anchor will form a helical knot, and the implantation is successful (see Figure 5 ).

Abstract

The invention relates to a knotted medical suture and a knotting method thereof. The suture includes a flexible anchor and a load suture, wherein the flexible anchor is a columnar flexible object, and the flexible anchor is spirally wound with the load suture in a half-surrounded mode. The knotting method includes the steps that after the flexible anchor is limited, a first thread end and a second thread end of the load suture are pulled at the same time, and the flexible anchor is deformed into a spiral knot; the effective area of the spiral knot is 2-4 times the maximum circumcircle area of the section of the flexible anchor. The knotted medical suture is a flexible rivet with thread, when the suture is a cylindrical body, the suture is implanted, and after being implanted, the suture becomes the spiral knot and is fixed in a bone to be a fixed point, so that the suture is used by a surgeon to repair the soft tissue of human body injury. Compared with the existing technology, the knotted medical suture has a larger diameter after being knotted and a more stable structure, and can provide larger and more stable fixing strength.

Description

technical field [0001] The invention belongs to the technical field of medical sutures, and relates to a knotted medical suture and a knotting method thereof, in particular to a knotted medical suture for repairing soft tissues and a knotting method thereof. Background technique [0002] Most soft tissue injuries are the complete or partial detachment of tendons, ligaments, or other soft tissues from bones, mainly in the joints of the human body. Injuries caused by excessive exercise or excessive force on soft tissues with age usually require surgery. At present, the common repair method in surgical operation is to use a wire anchor device to fix the detached soft tissue to the bone. [0003] The threaded anchor is to string the anchor on the suture and ensure that the anchor can slide freely left and right on the suture. [0004] At present, the anchors of commonly used anchor devices with wires are basically made of polymers, metals or biodegradable compounds. The implant...
