Abstract

A cannula sleeve for a surgical trocar assembly. The cannula sleeve includes a hollow shaft, at least a portion of which is made of a rigid material, and a seal at the distal end of the hollow shaft, the seal being movable between a first open position and a second closed position. The shaft defines a proximal end, a distal end, a periphery, and a longitudinal axis. The shaft further includes a channel at the periphery substantially parallel to the longitudinal axis, the channel being in communication with the hollow shaft.
