摘要

The pliers have jaws (1, 2) comprising sharp noses (4, 5) curved inwards to envelope and to capture a spinal rod. The jaws are articulated by clips composed of links (9-12) actuated by a threaded rod (6) comprising a neckline part supporting a spring that is blocked by a washer (16). The rod (6) has another neckline part at its inner base. The noses are extended by arms that are connected by an axle (3).
