Background
In recent years, due to the advent of arthroscopic surgery, surgeons view the inside of the joint cavity through arthroscope at the time of surgery, which tends to repair soft tissue back to bone through a small incision called portal. The belt loop titanium plate fixation method is an endoscopic technique in ACL reconstruction surgery (i.e., cruciate ligament reconstruction). The method can firmly fix the upper ends of the tendon grafts without bone blocks at the two ends in the femoral side bone canal by using a built-in belt loop titanium plate without adding external condyle side incision, and is one of the prior ACL reconstruction technologies by using the tendon grafts without bone blocks such as semitendinous tendon, femoral tendon and the like. In the operation process, the belt loop titanium plate is matched with the annular medical suture line, so that the operation process is faster and more convenient. The single medical suture line can be connected end to form a ring structure for operation. However, the existing 2 free end joints of a single medical suture form a medical suture loop, and are usually directly bonded or knotted and fixed by using an adhesive, and the knotting can lead to the great reduction of the mechanical property of the medical suture, so that the defects of unstable fixation, expansion of a fixed part, reduction of the mechanical property, influence on postoperative recovery of a patient and the like are easily caused.
In addition, the conventional medical suture has a circular cross section. In the surgical procedure, there are the following problems: the hardness of the round medical suture is high, the line-line of the line knot is in point contact, and the medical suture knot is easy to loosen; the medical suture line has longer thread head and larger thread knot, has stronger irritation to tissues and is not easy to recover after operation; the circular medical suture has the advantages that the friction force is minimum, the action on the tissue is mainly expressed in a pressure mode, the cutting force is stronger, and accidents that the tissue is cut off easily occur when the medical suture is pulled. Therefore, researches on a loop ring and a knitting process of the loop ring, which are firm, long in service life, favorable for operation and convenient for postoperative recovery of patients and are matched with a titanium plate with a loop, are urgently needed.

s2, relatively penetrating the end part A11 of the knitting section A8 into the hollow interior of the knitting section B9 to form a nesting part A13, and relatively penetrating the end part B12 of the knitting section B9 into the hollow interior of the knitting section A8 to form a nesting part B14, wherein the relative penetration means that the penetration directions of the knitting section A8 and the knitting section B9 are opposite;
s3, an end part A11 of the knitting section A8 penetrates out of the knitting section B9, and an end part B12 of the knitting section B9 penetrates out of the knitting section A8;
s4, tightening and merging joint parts, wherein the joint parts are parts between the nested parts A13 and the nested parts B14, and the length of the tightened joint parts is close to 0, so that the defects of unstable fixation, expansion of the fixed parts, uneven fineness of medical suture lines, reduced mechanical property and the like caused by overlong joint parts are overcome;
s5, relatively penetrating the exposed end A11 of the weaving section A8 into the hollow interior of the weaving section B9 again, repeatedly penetrating the end A11 into and out of the weaving section B9 to form a discontinuous nested structure, shearing off the exposed end A11, and fixing a cutting point through adhesive bonding or stitching or hot pressing;
s6, the exposed end B12 of the knitting segment B9 is oppositely penetrated into the hollow interior of the knitting segment A8 again, and repeatedly penetrated into and out of the knitting segment A8 to form a discontinuous nested structure, the exposed end B12 is sheared off, and the cutting point is fixed through adhesive bonding or stitching or hot pressing.
The invention relates to a using method matched with a belt loop titanium plate in operation, which comprises the following steps:
1) The implant is folded in half after penetrating the loop 2, and is bound by a medical suture;
2) Preparing two traction wires, wherein one traction wire is folded in half after passing through a traction hole A3 of the belt loop titanium plate 1, and the other traction wire is folded in half after passing through a traction hole B4 of the belt loop titanium plate 1;
3) The traction wire then drives the graft and belt loop titanium plate 1 to move and rest on cortical bone outside the bone canal.
