Description

Knotted composition that can be used for stitching

The present invention relates to a knotted composition, in particular to a knotted composition that can be used for sewing.

When the existing string is passed through the object and fixed, it is usually knotted at the end of the string to form a head or fixed knot to fasten the end of the string. For example, when a wound is sutured with a surgical suture, a needle is used to drive the surgical suture to cross both sides of the wound tissue and tie a knot at the end of the suture operation, so that the surgical suture can tighten the tissue on both sides of the wound, so that the wound can be tightened. healing effect.

In the above-mentioned method for fixing the rope, since the end of the rope needs to be knotted to form the head, the tying operation is complicated and time-consuming. When it needs to be fast, especially when it is used for surgical suturing of wounds, the operation of fixing the rope becomes less efficient, and it is necessary to improve the method to simplify the method of knotting the ends of the rope to form the head, and to speed up the operation of the surgical suturing of the wound.

Since the existing rope needs a complicated tying operation when forming a head or tying a knot at the end, the knotting process is particularly inefficient when used in the end of a surgically sutured wound. For this reason, the present invention, by pre-forming the structure of the slip knot, allows the user to use the slip knot to form the thread end structure on the wire when using the present invention, so as to achieve the knotting effect of quickly forming the thread end on the wire.

In order to achieve the above-mentioned creative purpose, the present invention provides a knotting composition that can be used for suturing, and is provided with an outer tube, a sliding tube is slidably inserted in the outer tube, and the front end of the sliding tube penetrates out of the outer tube to form a The sleeve part, a threading hole is formed through the sliding tube in the axial direction, and a tying wire is arranged, the wire body is wound around the sleeve part to form a slipknot with more than a single loop, and the rear end is inserted into the threading hole. The part of the tying wire located between the slip knot and the front end of the threading hole forms a bundle of ferrules, and more than one knotted line segment different from the tying wire is passed through the ferrule, and the rear end of the tying wire is pulled backwards , the size of the bundled ferrule is closed and the sleeve part is moved into the outer tube. At this time, the bundled ferrule folds more than one knotted line segment and forms a folded end that sinks into the front end of the threading hole. The sleeve part falls off and goes over the ferrule forward, and is tightly bundled at the inversion of one or more knotted line segments to form a thread end structure.

Further, the diameter size of the front end of the threading hole of the present invention is larger than the width dimension sufficient for the tie wire and the folded end to pass through, and is smaller than the tie wire and the folded part of one or more knotted line segments. Tie the wire around the width of a circle.

Furthermore, the slip knot of the present invention is a double loop slip knot or a three loop slip knot, and the tying wire and each knotted line segment are surgical sutures of the same size and specification.

Preferably, in the present invention, two or more knotted line segments are inserted into the ferrule, and the two or more knotted line segments are the parts where the same knotted wire is wound through the ferrule twice or more.

Further, in the present invention, the knotted wire segment described in the second section is inserted through the ferrule. After the knotted wire passes through the ferrule for the first time, it first passes through a tissue and then passes through the ferrule again. The portion of the wire that passes through the ferrule twice is the two knotted wire segments.

When using the present invention, the knotted line segment to be knotted is passed through the ferrule, and then the tying wire is pulled back, so as to easily form the thread head structure at the reverse fold of the knotted line segment. The operation of tying a knot at the end of the surgical suture wound or forming the head of various wires can speed up the operation of the surgical suture wound or quickly complete the knotting operation after various wires are tied.
