Abstract
A collar for a surgical access device includes an annular body laterally attachable to a cannula of the surgical access device. A spring is coupled to the annular body and movable between an uncompressed state and a compressed state. The spring is configured to manipulate the annular body between a first condition and a second condition to selectively fix the annular body at predetermined locations along the cannula or to laterally remove the annular body from the cannula while the cannula is supported within a patient's body.
