摘要：
A surgical cannula assembly includes an elongated cannula member, first and second expandable members mounted to respective proximal and distal portions of the cannula member, and a fluid-transfer assembly. The fluid-transfer assembly includes proximal and distal flanges coupled to the proximal portion of the cannula member. The first expandable member is disposed between the proximal and distal flanges such that movement of one of the proximal or distal flanges along the cannula member adjusts a pressure applied by the proximal and distal flanges on the first expandable member to transfer an inflation medium between the first and second expandable members.
