Embodiment Construction

[0016] The threads are formed on the surface of the suture body using any method within the purview of those skilled in the art, including but not limited to cutting, molding, and the like. Cutting devices can be produced at different angles, also by laser and manual methods. Molding includes injection molding, die punching, and the like. The ratio of the threads can be kept relatively constant, while the overall length of the threads and the spacing of the threads can be determined by the site used. Thread profile, spacing, and surface area can vary depending on the tissue in which the suture is used, as well as the composition and geometry of the material used to form the suture.

[0017] In specific implementation, such as figure 1 Sutures that can be used for urological surgery: Suture of residual cavity after deep myomectomy, preferably: PDO suture of absorbable material, size 0, continuous thread, thread 5 length 0.1mm-3.0mm, The included angle a is 30 degrees, the le...

Abstract

The invention discloses a suture line free of knot tying. The suture line is characterized by being provided with threads opposite to the needle threading direction. The threads carried by the suture line are used for preventing the suture line from backing up in the using process, tension generated after the line is sutured is evenly distributed, and the suture line is especially suitable for suturing blood vessels and other portions with high requirements.

Description

technical field [0001] The invention belongs to the field of surgical sutures, which can increase the tension in tissue after suturing and maintain uniform tension by forming threads on the sutures. Background technique [0002] Medical surgical suture is a kind of sterile thread used for wound healing, tissue ligation and tissue fixation. It plays an important role in the initial wound healing. The ideal suture should not bring dents, cracks to the healed tissue after injury. , blood clot and bacterial adhesion, and can meet the following conditions: high strength and retention rate synchronized with tissue healing, good flexibility, elasticity, operability, knotting and knot holding properties, certain extensibility to adapt to the wound Tissue edema, the wound can return to its original shape after healing; the cross-sectional diameter is as small as possible, reducing tissue reaction as much as possible; adapting to the needs of the skin, accelerating wound healing; non-...
