Surgical instrument, in which movements of the head and of the effector are decoupled

摘要

Surgical instrument comprises a handle part hinged on a proximal end section of a tubular shaft (2) having on its distal end section a pivoting instrument head for rotatably mounting an effector. The effector has at least one pivoting engaging element (30) operated via an effector-operating gear train using the handle part. The effector-operating gear train has a push bar (35) displaceably arranged in the tubular shaft and lying in contact with a push bolt (32) interacting with the engaging element and displaceably mounted in the instrument head and/or effector in the hinge region between the instrument head and the tubular shaft.
