Syringe for injectable fillers

Project Overview

Injectable fillers (fat grafts, collagen, hyaluronic acid, etc) are commonly used in plastic surgery to fill depressions or contour irregularities after extirpative cancer surgery or for cosmetic purposes. A frequent problem with these fillers is because of their viscosity, using standard syringes and simple thumb pressure leads to a lack of consistent volume deposition (i.e., lumpiness that is visible under the skin). We are trying to develop a simple syringe device that has some sort of ratchet mechanism (or something like it) for which a depressed plunger or button will administer a known volume (i.e., 0.1 mL). This would be similar to micropipettes, but would need to be much simpler (since it would need to be autoclavable, or cheaply manufactured if disposable). This device could later be used not only for plastic surgery but in other professions where a syringe and a desired amount of material is required to be expelled. Such an example would be in hair transplant procedures where syringes are used to apply small amounts of adhesive.
