Medical instrument

A medical instrument comprising:

• a hollow rod;
• a first fastening mechanism;
• and
• a second fastening mechanism, wherein at a distal end of the hollow rod, a tool carrier is securable by means of the first fastening mechanism, and at a proximal end of the hollow rod, an operating unit is securable by means of the second fastening mechanism, and wherein the first fastening mechanism for connecting the tool carrier to the distal end of the rod is configured as a mechanical latching connection having at least one resilient element,
• wherein the second fastening mechanism for connecting the proximal end of the rod to the operating unit is also configured as a mechanical latching connection having at least one resilient element,
• wherein the hollow rod and the tool carrier comprise components to be connected to one another, wherein the mechanical latching connection of the first fastening mechanism is comprised of at least one latching hook formed on one of the components of the hollow rod or the tool carrier to be connected to one another and at least one corresponding latching receptacle formed on the other component of the hollow rod or the tool carrier, for the at least one latching hook, wherein the hollow rod and the operating unit comprise components to be connected to one another, the mechanical latching connection of the second fastening mechanism is comprised of at least one latching hook formed on one of the components of the hollow rod or the operating unit to be connected to one another and at least one corresponding latching receptacle formed on the other component of the hollow rod or the operating unit, for the at least one latching hook of the second fastening mechanism, and
• wherein a cut-free spring tongue is formed on the component with the at least one latching receptacle of the first or second fastening mechanisms in a region of the latch, which the spring tongue is configured to be pressed radially inward to release the latching connection.
