US 2019/0160223 A1 · Pneumatic Vibrational Injection Apparatus

Abstract

A pneumatic vibrational injection apparatus suitable for use in a system for removal, delivery and/or transplantation of body tissues and other substances in medical procedures may include an apparatus housing having an air inlet chamber, an air outlet chamber, a connecting chamber connecting the air outlet chamber and the air inlet chamber and an injection chamber disposed between the air inlet chamber and the air outlet chamber. An injection nozzle may be disposed in fluid communication with the injection chamber. An injection cannula may be disposed in fluid communication with the injection nozzle. An inlet transducer wheel and an outlet transducer wheel may be mounted for rotation in the air inlet chamber and the air outlet chamber, respectively, of the apparatus housing. A vibration transducer may be disposed in physical contact with the inlet transducer wheel and the outlet transducer wheel. The injection nozzle may be disposed in physical contact with the vibration transducer. A syringe plunger may slidably engage the injection chamber in the apparatus housing.
