Description

Knot-free wound suturing components

The present invention relates to a wound suture assembly that does not require knotting, in particular, a device that can place a plurality of sutures in a stopper and be deformed by the stopper so that the plurality of sutures can be clamped by the stopper. It is durable and secure for fast and knotless sutures.

In the medical system, trauma can be divided into abrasions, contusions and lacerations based on the type of wound. Abrasions refer to damage to the skin surface, contusions refer to blunt injuries to soft tissues, and lacerations refer to the tearing of the skin due to external force. The wound affects the entire thickness of the skin and is discontinuous on the skin surface. Generally, it cannot heal on its own. The wound needs to be sutured closed by penetrating the skin with needle sutures.

Generally speaking, lacerations on the face exceeding 0.5 cm and lacerations exceeding 1 cm on other parts of the face need to be sutured to help the wound heal. There are two purposes of suturing the wound, one is to stop bleeding, and the other is to stop the bleeding. Align the wound so that it lies flat.

However, in surgical operations, the operator will use different instruments to perform knife steps according to different operations, make at least one wound on the patient's body, move objects into or out of the patient's body through the wound, and finally suture the patient's body. Means to suture the wound.

In addition, in endoscopic surgery or minimally invasive surgery, the medical practice of using tiny holes to enter the human body cavity to perform surgery can reduce post-operative pain as well as adhesion and infection caused during surgery. Among them, endoscopic surgery At this time, the operator cannot look directly at the surgical site and must look through the visual monitor. The screen determines and moves the operator's hands. Therefore, it is difficult for the operator to quickly and accurately perform the knotting steps in the suturing method.

Furthermore, whether it is a lacerated wound, a wound in a surgical operation, or a minimally invasive surgery, the surgical space around the wound is small, so the operator cannot easily complete the knotting step when performing suturing, and the suturing time will be shortened. was extended.

The main purpose of the present invention is to improve the structure of the wound suturing component so that the user can directly set multiple sutures in the stopper, and the stopper is deformed to shorten the distance between the two opposite ends of the stopper, allowing the plurality of sutures to be placed in the stopper. The suture is clamped and fixed by the stopper, so that when using suture with a needle, there is no need to knot the suture and save operation time.

The secondary purpose of the present invention is to improve the number of sutures with needle sutures, and to design the sutures to have at least two sutures, thereby reducing the chance of the wound being moved due to breakage of the sutures, thereby increasing the number of sutures. The thread can increase the friction between the suture and the wound site, and the friction between the two sutures is generated by contact with each other, thereby reducing the detachment of multiple sutures from the wound site.

Another object of the present invention is that the remaining parts of the plurality of sutures can be clamped by the tail end stopper to form a convergence part, so that the needle suture can be followed by the tail end stopper and the head end stop after being cut off. piece to suture another wound site. In order to achieve the aforementioned object, the knotless wound suture assembly of the present invention has a needle suture and a stopper. The needle suture has a needle and a plurality of sutures, and the needle is connected to one end of the plurality of sutures. And a tail end of the plurality of sutures jointly constructs a convergence portion.

However, the stopper constructs a positioning space for the plurality of sutures to pass through in a first state, wherein the stopper is made of silicone, metal, rubber, plastic or polylactic acid. Made of one of the biocompatible materials.

Wherein, the needle suture can be penetrated into a wound site and the stopper in sequence, so that the polymerization part is positioned at one end of the wound site to form a thread tail fixing structure; the stopper is formed from the first state It becomes a second state, so that the plurality of sutures passing through the positioning space can be clamped by the stopper to jointly form a thread fixing structure.

In addition, the suture is roughened so that the suture forms a rough surface to increase friction resistance, and a suture portion of the plurality of sutures located between the convergence part and the stopper will wrap up the wound. position, and a remaining portion of the plurality of sutures located outside the stopper will be cut, so that the sewing needle and the remaining portions of the plurality of sutures are separated from the suture portion of the plurality of sutures.

Furthermore, the remaining portion of the plurality of sutures can be clamped by a tail end stopper to form the convergence portion, so that the needle suture can be followed by the tail end stopper and an end after being cut off. The stopper is used to suture another wound site. The stopper, the tail end stopper and the head end stopper are composed of the same structure.
