The present invention relates to an ultrasonic aerosolization platform that has a single access port (10) provided with a trocar (11) inserted into the surgical cavity through a single incision and provided with at least one internal channel (101) in which is positioned an ultrasonic aerosolizer (20) provided with a head (21) that houses a power piezoelectric transducer (214) and a resonating rod (22) that extends orthogonally from the head (21), provided with an internal channel (221) in communication with the internal channel (212) of the head (21) and a free end (222) with an atomization nozzle (30) with orifices (31); a high-frequency ultrasound generator (40) that provides an electrical signal to the power piezoelectric transducer (214), which converts said electrical signal into mechanical oscillations transmitted to the resonating rod (22) in the form of mechanical standing waves; and a processing unit (50) provided with an interface (60) for adjusting the excitation frequency of the transducer (214), adjusting the flow of the therapeutic substance, and adjusting the operating and actuation time of the electrode (not shown) arranged in the resonating rod (22).
