1. A sleeve for use with a minimally invasive surgery suction instrument, comprising:

  • a tube having an inner lumen configured to receive an inner cannula of the suction instrument and allow the inner cannula to translate freely within the inner lumen, wherein the tube comprises a first segment and a second segment joined by a connector, the connector comprising;

    an outer connection member at the end of the first segment;

    an inner connection member at an end of the second segment and configured to insert into the outer connection member; and

    an O-ring seated within the outer connection member and configured to support the inner cannula of the suction instrument and form a seal between the inner cannula and the inner lumen;

    a distal end of the tube configured to insert into an introducer port, the distal end having a plurality of radially facing apertures and an axially facing opening; and

    a proximal end connected to the tube and configured to facilitate grasping and manipulation by a user to translate the sleeve between a first position exposing a distal tip of the inner cannula beyond the axially facing opening of the tube and a second position where the distal tip of the inner cannula is seated within the inner lumen of the tube, proximal to the radially facing apertures.
