Abstract
The present disclosure relates to a surgical cannula with a removable seal at one end. The surgical cannula is a wide gauge surgical cannula, that allows materials and tools to be introduced into a body during a surgical procedure. The cannula includes a seal structure at one end, which may be attached to and detached from the cannula body as desired. The seal structure includes one or more valves that retain pressure within the cannula. The one or more valves are configured to allow a tool through the valve(s), while retaining pressure inside the cannula, so that surgical tools may be inserted through the cannula even when the seal structure is attached to an end of the cannula.
