An integrated needle and cannula assembly for plastic surgery including a syringe connected to a blunt-tipped cannula where the blunt-tipped cannula is inserted into the hollow annular space of a hypodermic needle. In operation, the medical practitioner penetrates into the patient's skin using the hypodermic needle and then slides the blunt-tipped cannula through the annular space of the needle. A transporter assembly can be interposed between the syringe and the overlapping needle/cannula. The transporter assembly may include a retractable inner needle tube attached to the hypodermic needle and an external transporter housing which connects the syringe to the cannula through a cannula connector. Once the blunt tipped cannula is under the patient's skin, the needle is preferably withdrawn from the patient's skin to allow sub-dermal substances to be injected using only the blunt-tipped cannula. Withdrawal of the needle can be assisted with either a pull spring or push spring. In an alternative embodiment, a sharp-tipped trocar inside a cannula is used to penetrate the patient's skin. In a further alternative embodiment, a barbed surgical thread may be attached to said cannula to perform thread-lift procedures.

A reuse prevention mechanism includes a guidance arm with a pin engaged in a guidance contour adapted to control movement of the guidance pin, and a blocking part adapted to block access to a needle in a fourth position of the reuse prevention mechanism. The guidance contour is adapted to constrict linear movement of the reuse prevention mechanism in a direction from a first position to a third position.

The present invention relates to a needle arrangement for an injection device. The needle arrangement is made up from needle cannula which is mounted such that a distal part having a distal tip extends in a distal direction. Further, a telescopically movable shield carrying a cleaning chamber surrounds at least the tip of the needle cannula between injections such that the tip of the needle cannula is maintained inside the cleaning chamber between subsequent injections. The cleaning chamber is at least distally provided with a pierceable septum through which the needle cannula penetrates during injections. For guiding the needle cannula during injections a telescopically movable tube is provided. During injections the distal end of the telescopically movable tube at least partly penetrates the distal septum.
