A tool for a medical instrument includes a stationary component, a branch which is pivotable relative to the stationary component about a pivot axis, a transmission device for transmitting a force to the pivotable branch, and a coupling device for coupling the transmission device to the pivotable branch in such a way that a translation of the transmission device entails a pivoting movement of the pivotable branch about its pivot axis. The coupling device includes several coupling portions on the pivotable branch and several coupling portions on the transmission device. Each coupling portion on the pivotable branch is assigned to a corresponding coupling portion on the transmission device. The coupling portions are arranged and designed such that the coupling of pivotable branch and transmission device is effected, depending on the positions of pivotable branch and transmission device, by different pairs of corresponding coupling portions.
