A sterile, rigid or semi-rigid, hand-held plastic tube designed as a conduit for the evacuation (suctioning) of blood, fluids, and other tissue debris directly from the surgical site during a surgical procedure (e.g., open- or plastic surgery). Also known as a suction tube, it is typically a general-purpose device to which the suction system tubing is connected proximally; some types may be attached to a dedicated handpiece that typically have a valve. Dedicated cannula specifically intended for a particular procedure (e.g., bronchial, dental, eye, uterine, oral, and liposuction) are also available. This is a single-use device.
