Medical instrument

A medical instrument comprising an instrument insert (42) and an instrument handle (1) which are detachably connectable to one another, the instrument insert (42) having an actuation rod (52), the instrument handle (1) having a movable grip (4) and a receiver (10) connected to the movable grip (4), the receiver (10) adapted to receive a proximal end of the actuation rod (52) for connection thereto, the actuation rod (52) and the movable grip (4) being detachably connectable to one another via a locking connection (12, 54) such that movement of the movable grip moves the actuation rod along a longitudinal axis (X), a blocking element (14) preventing movement of the movable grip (4) along the longitudinal axis when the actuation rod (52) is detached, the movable grip being held in a defined location by the blocking element when the instrument handle is detached from the instrument insert, a cylinder sleeve (8) being arranged at least partially inside the receiver (10), the cylinder sleeve (8) being movable with respect to the receiver (10), the cylinder sleeve (8) having a longitudinal passageway extending completely therethrough, the passageway of the cylinder sleeve (8) receiving therein at least a portion of a connection part (6) connecting the moveable grip (4) with the cylinder sleeve (8), the blocking element (14) being arranged inside the cylinder sleeve (8) with a spring element (16), such that the blocking element (14) is urged into a blocking position by the spring element (16) and is urged into a released position by the proximal end of the actuation rod (52) against a spring force of the spring element (16).
