Abstract
Abstract A surgical suturing instrument has a first guide limb (1) and a second guide limb (2) which start with their proximal ends from a connection part (8) and whose intermediate area is accessible from their distal ends (5, 6). A part of the intermediate area is occupied by a guide member (20) which is designed and mounted in such a way that a thread introduced transversely in proximal direction into the intermediate area is inevitably guided by means of the guide member (20) essentially along the first guide limb (1) until it has passed a guide point (P), and the thread, upon the return movement in distal direction, is inevitably guided by means of the guide member (20) essentially along the second guide limb (2). The end of the surgical thread is secured (S) in the middle zone of a side surface of the guide member (20). The other end of the surgical thread is attached in the front zone of a bent surgical needle.
