Description

This invention relates to suture needles, and more particularly to capsule needle modules. As modern medical technology continues to advance, the demands on surgery are also shifting towards smaller incisions and minimally invasive procedures. These techniques not only achieve rapid and effective wound healing but also help to minimize and improve scarring after healing. In conventional techniques, when a surgeon wants to suture a wound, they typically hold a suture needle equipped with surgical sutures, suture the tissues on both sides of the wound, and form a knot to secure the end of the surgical suture. However, the conventional techniques described above require the surgeon to manually wrap the surgical suture to form a fixation knot. This process is cumbersome, and the small size of the wound hinders the manual wrapping motion, leading to a decrease in the quality of the fixation knot. Forming multiple fixation knots in the wound using the above method not only increases the overall time required and is inefficient, but if the knots are not properly tied, the wound is more likely to dehiscence, affecting the patient's recovery efficiency.

To further clarify the purpose, technical proposal, and advantages of the embodiments of the present invention, the technical proposal of the embodiments will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. However, the embodiments described are only some, not all, embodiments of the present invention. Those skilled in the art will know that all other embodiments based on the embodiments of the present invention, performed without creative labor, are all within the scope of protection of the present invention. Figures 1 to 3b show a first preferred embodiment of the capsule needle module provided by the present invention, which includes an axially arranged operating control member 10 and a knotting member 20. The operating control member 10 is installed at the rear end, and the knotting member 20 is installed at the front end. The knotting member 20 is provided with a through hole 21 through which a suture A can be passed, and the operating end of the suture A is connected to any part of the operating control member 10. The method of connecting the suture A to the operating control member 10 is not limited and may be by adhesive fixation or knotting. In this embodiment, the operating control member 10 includes a radially positioned thread puller 12, and the operating end of the suture A can be tied to the thread puller 12. An outer fitting shaft 22, which protrudes from the front end, is installed within the through hole 21 of the knotting member 20, and the outer fitting shaft 22 is hollow tubular. The other end of the suture A, opposite the operating end, is the suture end. After passing through the through hole 21 and the outer fitting shaft 22 at the suture end, the suture A extends toward the front end and is exposed outside the capsule needle module. The suture end of the suture A that is exposed outside the capsule needle module is wrapped around the outer circumference of the outer fitting shaft 22, forming a pre-knot A1 and a movable ring A2 formed between the outer fitting shaft 22 and the pre-knot A1. A suture needle B is connected to the end of the suture end of the suture A, and it is used to suture and fix a tissue wound. In the first embodiment, at least a portion of the outer fitting shaft 22 is fixedly installed within the through hole 21. When operating the capsule needle module, the operator aligns the front end of the knotting member 20 with the expected suture location and passes it through the movable ring A2. Furthermore, during suturing, a suture different from suture A may be used and passed through the movable ring A2. After suturing is complete, the operator operates the operation control member 10 to separate it from the knotting member 20, pulls the operating end of suture A via the operation control member 10, and shrinks the movable ring A2 until at least a portion of the movable ring A2 is attached to the outer circumference of the outer fitting shaft 22. Next, the operation control m
