Description

Technical Field

[0001] The invention relates to a surgical suturing device, in particular to a medical thread loop. Background Art

[0002] With the widespread development of laparoscopic technology, repairing damaged tissue requires knotting within a confined space. Conventional surgical knotting techniques are not feasible. Instead, the knot must be tied externally using an axis as support, then slid into the body along the axis, utilizing the initial tension generated by the sliding locking knot to align the repaired tissue. Although knotless suture anchors have become increasingly popular in recent years, the technique of tying a sliding locking knot remains a crucial skill for arthroscopists. As an initial knot, the sliding locking knot provides sufficient aligning tension to connect retracted tendinous tissue to the bone anchor or eliminate large tissue gaps, making it crucial for surgical success. A so-called sliding locking knot consists of an axis and a loop. The knot can be easily opened by pulling out the axis. After the knot is tied, it is tightened by pulling the axis until the sutured tissue is tightened to a desired tension. A knotting aid is then used to tighten the suture on the other side, at which point the knot is locked. The sliding locking knot needs to be tied on-site during the operation, which increases the surgical steps and operation time; on-site knotting has certain requirements for the knotting skills of medical personnel, and they need to be trained and master the knotting method in advance. Beginners sometimes make mistakes during the knotting process, causing the knot to lose its sliding ability or be locked by mistake, which prolongs the operation time and even affects the treatment effect. Summary of the Invention

[0003] The present invention aims to solve the above problems existing in the prior art and provide a medical wire loop capable of forming a sliding locking knot.

[0004] The technical solution of the present invention is: A medical wire loop includes a suture thread, and its special feature is that: wire loop one and wire loop two are wound on the suture thread, and the lead-out ends of the suture thread corresponding to wire loop one and wire loop two are respectively led out to the opposite wire loop, and the lead-out section of wire loop one and the lead-out section of wire loop two are located on the same side of the connecting section of wire loop one and wire loop two or on both sides of the connecting section of wire loop one and wire loop two. When the lead-out section of wire loop one and the lead-out section of wire loop two are located on both sides of the connecting section of wire loop one and wire loop two, the lead-out section of one of the wire loops passes through the other wire loop, i.e., the opposite wire loop, and the lead-out section of wire loop one and the lead-out section of wire loop two are clamped by the buckled wire loop one and wire loop two.

[0005] Furthermore, the wire loop 1 and the wire loop 2 are supported by a support member passing through them, or the wire loop 1 and the wire loop 2 are overlapped after being buckled together.

[0006] Furthermore, the first and second thread loops are supported by a suture gun needle tube or a suture hook.

[0007] Furthermore, when the lead-out section of the thread loop one and the lead-out section of the thread loop two are located on the same side of the connecting section of the thread loop one and the thread loop two, a suture needle is provided at either end of the suture thread.

[0008] Furthermore, when the lead-out section of the wire loop one and the lead-out section of the wire loop two are located on both sides of the connecting section of the wire loop one and the wire loop two, a suture needle is provided at one end of the wire loop lead-out section passing through the opposite wire loop.

[0009] Furthermore, the first and second wire loops are in the shape of an "8".

[0010] Furthermore, the overlapping wire loops 1 and 2 are clamped and maintained in the overlapping state by self-adhesive or medical tape or a clamping piece.

[0011] The present invention has the beneficial effects of enabling pre-standardized knotting to meet the requirements of industrial automated production. It eliminates the need for additional knotting steps during surgery and the risk of misoperation caused by on-site knotting. The knot is small, and after suturing, the suture thread is passed through overlapping loops to form an axis. The overlapping loops are then slid and tightened along the axis to lock, forming a sliding locking knot. This sliding locking knot is easy to slide and highly stable, streamlining surgical steps and shortening operative time, particularly for microsurgical procedures such as vascular and vascular-lymphatic anastomosis, ensuring surgical efficacy.

The lead-out section 101 of suture loop 1 leads toward suture loop 2, while the lead-out section 201 of suture loop 2 leads toward suture loop 1. The lead-out sections 101 and 201 extend in opposite directions, and the length of the lead-out section 201 is greater than that of the lead-out section 101 to facilitate operation. The lead-out sections 101 and 201 of suture loop 1 are located on the same side (rear side) of the connecting section 3 of suture loop 1 and suture loop 2. The lead-out sections 101 and 201, as well as the lead-out sections 201 and suture loop 1, respectively, are in a cross-shaped configuration and can be wrapped around the suture loops 1 and 2 after they are fastened. suture loops 1 and 2 are supported by a tubular support member 4 passing through them.

Other structures are the same as Example 1.

[0019] During use, the tip of the suture needle 5 passes through the suture site to form a rope loop, and then the suture needle drives the suture thread through the overlapping thread loop and serves as the axis. The clamping part 6 is removed, and the axis is pulled to slide the thread loop toward the suture site to tighten the rope loop, and then the two ends of the suture thread are alternately pushed or tightened to form a locking knot with the overlapping thread loops.

[0020] Example 4 like Figure 6 As shown, the present invention includes a suturing gun 7. The support member 4 in Example 1 is replaced with the suturing gun 7. Thread loop 1 and thread loop 2 are placed on the needle tube 8 of the suturing gun 7. Suturing is performed according to the operating instructions of the suturing gun. Other steps are the same as those in Example 1.

[0021] Example 5 like Figure 7 As shown, a medical wire loop includes a suture thread, and the suture thread is used to wind wire loop 1 and wire loop 2, the lead-out section 101 of wire loop 1 is led toward wire loop 2, and the lead-out section 201 of wire loop 2 is led toward wire loop 1, the lead-out section 201 of wire loop 2 is located on the front side of the connecting section 3 of wire loop 1 and wire loop 2, and the lead-out section 101 of wire loop 1 is located on the rear side of the connecting section 3 of wire loop 1 and wire loop 2, the lead-out section 201 of wire loop 2 passes through wire loop 1 from front to back, the lead-out sections 101 and 201 are wrapped by the fastened wire loop 1 and wire loop 2, the wire loop 1 and wire loop 2 are supported by a tubular support 4 passing through them, and the suture thread is connected to a suture needle 5 at one end of the lead-out section 201 of wire loop 2.

[0022] When in use, first pass the needle tip end of the suture needle 5 through the suture site to form a rope loop, overlap the thread loop 1 and the thread loop 2, then make the suture needle 5 drive the suture thread through the thread loop 2 and the thread loop 1 in sequence, remove the support member 4, pull the axis to make the thread loop slide toward the suture site, tighten the rope loop, and then alternately push or tighten the two ends of the suture thread to form a locking knot with the overlapping thread loops.
