摘要

Torque wrench (1) for connecting a replaceable instrument tip (20) to a hand piece that carries the replaceable instrument tip (20) in operation, comprising- a base element (2) having a receiving region (15) for placing the instrument tip inside the receiving region (15) at least during connecting the instrument tip (20) to the hand piece,- a torque wrench mechanism for applying a certain torque when connecting the instrument tip (20) to the hand piece and- a housing (10) surrounding the instrument tip (20) being arranged in the receiving region (15), the housing being preferably transparent,-- wherein the torque wrench (1) has a guiding structure (4) for aligning the torque wrench (1) relative to the hand piece during arranging the torque wrench (1) on the hand piece, in particular in an interface region of the hand piece, and/or-- wherein the housing (10) has an inner surface (11) and an outer surface (12) being concentric to each other over a complete primary region (31) extending at least from the base element (2) to the end (25) of the instrument tip (20), when the torque wrench (1) is equipped with the instrument tip (20).
