Abstract
The present disclosure provides for an interlocking cannula system that includes a handle and a set of cannulas. The set of cannulas includes a sequence of smaller to larger cannulas constructed such that the smaller cannulas may be nested within larger cannulas. Each cannula in the set of cannulas includes a respective locking mechanism configured such that each cannula may be interlocked with each of the other cannulas in the set. The handle is constructed such that each cannula in the set may interlock with the handle by the respective locking mechanism of the cannula. In some instances, the respective locking mechanisms are constructed to enable an ordered release of the cannulas.
