Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dental medical technology, and specifically relates to a barbed suture. Background Technology
[0002] In the field of dental medicine, oral and maxillofacial surgery is a common treatment method used to address various oral and maxillofacial diseases, trauma, and deformity correction. Tissue suturing is a crucial step in these surgeries, as the quality of the suturing directly affects the success rate of the surgery, the patient's recovery speed, and the postoperative aesthetics and functional recovery.
[0003] Traditional dental sutures are mostly smooth. When suturing tissue, these smooth sutures mainly rely on knots to fix the suture and close the incision. However, the oral and maxillofacial tissues have unique physiological characteristics and mechanical environment. On the one hand, the oral and maxillofacial tissues are frequently active, such as chewing, speaking, and facial expressions. These activities will generate continuous tension on the incision. Because smooth sutures lack effective tissue holding force, they are prone to sliding in the tissue when subjected to greater tension, which will cause the tissues on both sides of the incision to not be tightly adhered, thereby increasing the risk of incision dehiscence. Incision dehiscence will not only prolong the patient's healing time and increase the probability of complications such as infection, but may also require secondary suturing, bringing more pain and economic burden to the patient.
[0004] To address the issue of insufficient gripping force in smooth sutures, some barbed sutures have emerged on the market. However, existing barbed sutures have some design limitations. The barbs in some barbed sutures are poorly designed, with uneven distribution or a single arrangement, resulting in limited improvement in tissue gripping force. They are still unable to effectively cope with the complex mechanical environment of the oral and maxillofacial region. Moreover, the processing technology of some barbed sutures is complex, and the production of barbs requires special equipment and high technical requirements. This not only increases production costs but also leads to low production efficiency, limiting their widespread clinical application. Furthermore, the existing suture anchoring ring structure has poor stability. Therefore, this utility model proposes a barbed suture. Utility Model Content
