1. A medical device, comprising:
a sheath element suitable of being brought into contact, during a surgical operation, with live hard tissue and/or with hard tissue replacement material, the sheath element having a longitudinal bore defining a longitudinal opening reaching from a proximal end of the sheath element into a distal direction, and a plurality of holes in a wall of the opening,
a liquefiable element that is insertable or inserted in the longitudinal opening and at least partly liquefiable by the impact of energy impinging from the proximal side so that liquefied material flows through the plurality of holes in the wall and out of the longitudinal opening into structures of the hard tissue and/or hard tissue replacement material,
a first distal stop face against which a distal end of the liquefiable element is pressable for liquefaction, the first distal stop face being at a first position, and
an insert element comprising a second distal stop face against which the distal end of the liquefiable element is pressable for liquefaction after insertion of the insert element into the longitudinal opening, wherein the insert element is insertable from a proximal side into the longitudinal opening and shaped to be stopped at a position in which the second distal stop face is at a second position different from the first position.
