INSUFFLATION SYSTEM

摘要

An aerosol generator is positioned adjacent to a patient as an attachment to a trocar. The trocar has an entry port for insufflation gas. Aerosol generated by a vibrating element is entrained in the insufflation gas and the mixture is delivered through the trocar. The aerosol may contain a medicament. The trocar may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolized 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 aerosolized medicament to the pneumoperitoneum regions. The surgeon can temporarily remove the camera from the trocar port to facilitate insertion and positioning of the aerosolizing unit.

主权项

1. Apparatus for use in procedures involving insufflation, comprising:
an aerosol generator for aerosolizing a fluid; a trocar for delivery of the aerosol, the trocar comprising a housing to which the aerosol generator is mounted, the trocar having a proximal entry part for insufflation gas and a distal end through which aerosol is delivered; and an aerosol delivery tube extending from the aerosol generator into the trocar housing, the aerosol delivery tube having an aerosol outlet located distally with respect to the insufflation gas entry port of the trocar.
