Abstract
Cannula assemblies and methods of conducting surgeries. The cannula assembly comprises a cannula that is sized for the common 4 mm arthroscopy switching stick, which is put in a one-step fashion with the use of a unique switching stick inserter. All steps for placement of the cannula are performed in a single forward motion, i.e., no backing up of components are necessary for placement. The method of conducting surgery includes the steps of: providing a cannula/switching stick assembly comprising a cannula sized to accommodate a corresponding switching stick, and a switching stick inserter (modular handle) designed to fit on the switching stick, and to help insert and control the switching stick; and inserting the cannula/switching stick assembly through an arthroscopic portal during a surgical procedure, in a single forward motion.
