The second elongate cannula has a side wall and a lumen. The side wall has a vacuum side port in fluid communication with the lumen. A vacuum source is positioned in the housing body. The vacuum source has a chamber side wall, which may define a U-shaped volume, and has a chamber vacuum port. A seal is interposed in sealing engagement between the chamber vacuum port and the second elongate cannula. A trigger slide assembly is configured to move the second elongate cannula to align the vacuum side port of the second elongate cannula with the chamber vacuum port of the vacuum source to supply vacuum from the vacuum source to the lumen of the second elongate cannula.
