The invention relates to a torque wrench ( 1 ) which is embodied as a ratchet instrument in the medical field. A catch segment ( 40 ) which can be displaced in a defined manner is arranged on the periphery of the receiving opening, and the front part thereof is oriented towards the receiving opening. When the torque wrench ( 1 ) is actuated in a forward direction, the torque which is to be generated is applied by means of a forward force (F) exerted by means of a user, by a deflectable, preferably linear-elastic flexible arm ( 7 ). A catch spring extends from the catch segment into the neck area. The catch segment and the catch spring form a single-pieced or several part catch ( 4 ). The catch segment and the catch spring are arranged in a channel-shaped space ( 5 ) which enables said two elements to be deviated on the plane counter to the force of the catch spring. The catch ( 4 ) is a single-piece with the neck part or is fixed thereto as a separate component.
