A bone idler implanting system comprises a bag (1) and a delivery device (2). A distal end of the bag (1) is fixedly connected to a sealing head (11)； the sealing head is closed at its distal end and has a blind hole (111) at its proximal end, and the blind hole (11) has an opening towards the interior of the bag (1). The bag (1) has micro-pores (12). The delivery device (2) comprises a liner core (23), a delivery tube (21), and a sleeve tube (22). The delivery tube (21) is a rigid tube, and a distal end of the delivery tube (21) is detachably connected to a. proximal end of the bag (1). When the delivery device (2) is operated, the sleeve tube (22) slides axially towards the proximal end of the conveying tube (21), and the bag (1) is exposed.
