摘要：
The invention relates to a drive mechanism (9) for a needle insertion arrangement (1), the drive mechanism (9) comprising: —an actuator (5), —a needle retainer (7) adapted to retain an injection needle (2) and linearly movable in a distal direction (D) and a proximal direction (P) for moving an injection needle (2), —a cam (17) arranged on or coupled to the needle retainer (7), —a guide curve (16) adapted to be rotated by the actuator (5) about an axis (12) aligned in the distal direction (D) and the proximal direction (P) and adapted to engage the cam (17), wherein the guide curve (16) comprises a sloped section (16.2) such that the needle retainer (7) is moved on rotation of the guide curve (16).
