Abstract:
A cannula assembly for the maintenance of an operative pneumoperitoneum in a patient comprising an elongated cannula having a proximal end and a distal end. A removable valve is securely arranged in the proximal end of the cannula to provide a seal and minimize the escape of gas introduced into the patient's pneumoperitoneum when an operative instrument is passed therethrough.
