1. A cannula system comprising:
- a cannula, comprising;
a handle and a cannula shaft, the handle comprising a handle body having a proximal portion and a distal portion, the cannula shaft comprising an elongate tubular body having a proximal end depending from the distal portion of the handle body, a distal end terminating in a pointed tip, and a longitudinal axis extending therethrough;
the handle further comprising a first entry port in fluid communication with a first lumen;
the cannula shaft further having an inner wall defining a first channel, the first channel having a proximal end and a distal end, the proximal end of the first channel in fluid communication with the first lumen of the handle body, the distal end of the first channel in fluid communication with a first side distal exit port and spaced apart from the distal end of the elongate body, the inner wall configured to laterally deflect the first channel at the first channel'"'"'s distal end with respect to the longitudinal axis of the elongate body to transition the first channel'"'"'s distal end to the first side distal exit port;
an orthopedic surgical tool sized to be inserted into the first entry port of the handle and the channel of the cannula shaft; and
one or more spacers, each spacer having a proximal contact surface, a distal contact surface, and a through hole extending through the proximal contact surface and the distal contact surface.

Abstract
The present invention generally provides a cannula system that is readily maneuverable in an operating room setting, can be used to expose different instrumentalities to a target site, and has directional capabilities to allow the user to treat multiple quadrants or areas of a target site. The present invention provides cannula systems including these different instrumentalities as well as methods of operating these cannula systems and methods of treating orthopedic conditions using these cannula systems.
