The role of catheter In Aesthetic medicine

by Tina Liling SEO Assistant

In Aesthetic medicine, a Blunt-tip microcannula (also called smooth tip microcannula, Blunt tipped cannula or simply blunt needle) is a small catheter, with an edge that is not sharp, designed for atraumatic intradermal injections of fluids. Depending on the size of the inter diameter, it can be used either for fat transfer, or for the injection of fillers, like Hyaluronic Acid, Collagen, poly-L-lactic acid, CaHA, etc. The advantage of using these cannulas is that they are less painful, have less risk of bruising, and have a better safety profile. An intravascular injection is near impossible with the cannulas making the risk of blindness when injecting around the eye much safer. Skin necrosis risk is also lowered.

As of January 2012, the Dermasculpt microcannula is the sole blunt-tipped, flexible cannula approved by the FDA for use in the United States for use with soft tissue fillers.

Cannulae are used in body piercing when using a standard IV needle (usually between 18GA and 12GA, although may be as large as 0GA, in which case the procedure is known as dermal punching and uses a biopsy punch without a cannula), and for inserting hooks for suspensions.

During piercing, the fistula is created by inserting the needle. The needle is then removed, leaving the cannula in place, which is sometimes trimmed down. The cannula is then removed and sterile jewelry is inserted into the fistula simultaneously, in order to minimise trauma to the fresh fistula caused by insertion of blunt-ended jewelry.
