ABSTRACT The invention concerns a device to check the tension of a suture during a surgical operation. A forceps (2, 2') comprises two jaws which can pivot on one another, around a axis (Y-Y) to tighten a suture, and it can pivot around another axis, almost perpendicular to the first. A spring (15), whose force can be adjusted, main- tains it in one position (2) in which in can be used as a conventional forceps, but if the pulling force applied to the suture exceeds a predetermined limit in a defined direc- tion (21), the forceps pivots, and this visualizes the excess. According to another design, a piezoelectric element or a stress gauge is used to emit an information signal when the selected limit tension is exceeded.
