Insufflation system

Abstract

An aerosol generator 200 is positioned adjacent to a patient as an attachment to a trocar 201. The trocar has an entry port 203 for insufflation gas 208. Aerosol 207 generated by a vibrating element 205 is entrained in the insufflation gas and the mixture 209 is delivered through the trocar 201. The aerosol may contain a medicament. The trocar 201 may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolised medicament can occur at the start of the procedure and be delivered in bolus. At the start of the procedure, the peritoneum is being inflated by means of the flow of insufflator gas. This gas flow will help to entrain the aerosolised medicament to the pneumoperitoneum regions. The surgeon can temporarily remove a camera from the trocar port to facilitate insertion and positioning of the aerosolising unit.
