A medical instrument has a shaft, which has a distal end and a proximal end, with a jaw head which is arranged at the distal end and is pivotable out from the longitudinal axis of the shaft, wherein the jaw head has two jaw parts, of which at least one is pivotable, furthermore, with a first actuation element for pivoting the jaw head, and with a second actuation element for pivoting the pivotable jaw part, wherein the actuation elements are received in the shaft, and with control elements which are arranged at the proximal end of the shaft and are used for controlling the movement of the actuation elements. The actuation elements are arranged extending coaxially with respect to each other, and that the actuation elements are received in the shaft so as to be rotatable jointly about the shaft axis and to be rotatable relative to the shaft. |

1. A medical instrument, comprising
a hollow shaft having a distal end and a proximal end, a jaw head arranged at said distal end of said shaft,
said jaw head having two jaw parts, at least one of said two jaw parts is pivotable,said jaw head together with said two jaw parts being pivotable out from a longitudinal axis of said shaft,a first actuation element for pivoting said jaw head out from said longitudinal axis, at least one second actuation element for pivoting said at least one pivotable jaw part,
said actuation elements are housed in said hollow shaft, control elements arranged at said proximal end of said shaft, said control elements are for controlling a movement of said actuation elements housed in said shaft, wherein said actuation elements being arranged coaxially with respect to each other within said shaft, and wherein said actuation elements are jointly rotatable about said shaft axis, and wherein said jointly rotatable actuation elements are rotatably relative to said shaft. |
