    摘要： A tube body includes an interior bore to carry a material flow into bone. The tube body includes a dispensing end having an opening communicating with the bore to dispense the material flow. One embodiment provides a cutting element, which extends in the opening to permit passage of the material flow and to sever the material flow in response to rotation of the tube body. Another embodiment deflects the dispensing end from the main axis of the tube body, to facilitate targeted introduction of flowable material, even when the access path does not align the tube body along the natural geometric axes of the treatment site. Another embodiment provides a connector having a rotating fitting, which releasably connects the tube body to a cement injecting tool. The rotating fitting allows the physician to rotate the injection nozzle assembly to control orientation and position in the treatment site, without rotating the associated injection tool itself.
