Abstract
A cannula fixation system that allows for easy insertion and removal. A flexible sleeve with corrugations and proximal flange is attached distally to the cannula. The flange serves as a splashguard and a finger retention device. The corrugations have a variable diameter depending upon the tension applied to the proximal flange. The flange is pulled proximally to reduce the diameter of the corrugations for insertion of the cannula. Upon release of the flange, the corrugations expand because of the inherent resiliency of the sleeve to seal against the portal in the patient. The cannula body can be shifted with the sleeve remaining in sealing contact with the portal.
