A positional guide for use on a cannula shaft includes a shaft portion configured to form a first opening to receive a cannula shaft therein. One or more offset portions are connected to the shaft portion and configured to form second openings spaced apart from the first opening. The second openings are configured to each receive a stabilization device therein such that when the cannula shaft and the stabilization device are present in the first opening and the second openings, respectively, the cannula shaft and the stabilization device are disposed substantially parallel to each other. Methods are also disclosed. |
