Abstract
A surgical suture material is provided with a thread (1) and, in some cases, a needle (2) to allow formation of a knot with the greatest possible security while expending little effort, even in situations where space is limited--for example, during an endoscopic operation. The suture material has at least one inherently stable coil, loop or similar preformed feature in at least one initial preformed section (3,4) of its length. Another section of the thread (1) or an end of the thread can be threaded or guided through this preformed feature for the purpose of forming a loop and/or knot. The preformed section can take the form of a preformed feature with an approximately spiral shape, for example.
Claims29
Surgical suture material comprising a length of surgical thread having at least two initial preformed sections in spaced relationship to each other along its length, a free thread end extending from one side of one of said preformed sections and an opposite thread end extending from an opposite side of said another of said preformed sections, each said preformed section comprising a preformed feature having at least one inherently stable loop, said at least one loop of one preformed section having a direction of rotation opposing a direction of rotation of said at least one loop in another preformed section, such that when the free thread and is guided through a preformed feature from an opposite side of a preformed section and the ends are pulled away from each other, a knot is automatically formed in the thread.
