According to an embodiment, an inserter for installing a medical device via rotation in a recipient is disclosed. The inserter includes a longitudinal member adapted to rotate around a member axis, the longitudinal member comprising a first end and a second end. A grip unit at the first end is provided. The grip unit is adapted to grip the medical device. A shank member proximal to the second end is also provided. The shank member is adapted to engage with a drive unit that is adapted to provide a rotational force to the longitudinal member such that the gripped medical device is rotated around the member axis. The inserter includes an indicator unit adapted to provide a visual indication of number of turns of the longitudinal member when driven by the drive unit.
