A tool for a medical instrument, comprising:
- an effecting device;
- a transmission rod movable relative to the effecting device, of which the distal end is coupled to the effecting device, for transmitting at least either a force or a torque to the effecting device;
- a cutting device, which, to cut tissue, is movable in a channel in the transmission rod and in the effecting device, the channel including a groove in the transmission rod;
- at least either the cutting device or the groove is designed such that a movement of the cutting device in a proximal direction accompanies a lifting out of the cutting device from the groove for removal from the tool.
