Abstract: 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 Once the blunt tipped cannula is under the patient's skin, the needle is preferably withdrawn from the patient's skin to allow sub-dermal substances to be injected using only the blunt-tipped cannula.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.
