The invention relates to an indwelling cannula () for puncturing a hollow body by means of a puncture needle, wherein the indwelling cannula () has a catheter () with a vasiform catheter tube (), in which the puncture needle can be guided longitudinally displaceably. The indwelling cannula () has a manually actuable forward feed mechanism () by which a relative movement can be generated between the catheter tube () and the puncture needle as a result of manual actuation, by which a puncture tip (), protruding from the catheter tube () at the near-patient end, of the puncture needle can be received in the catheter tube (). Preferably, at least one operating element of the forward feed mechanism () is configured as a pivotably mounted lever () with at least one lever arm.
