A surgical suction device is disclosed that includes a suction tube having a first longitudinal axis, a proximal opening, and a distal opening; a guide tube that is substantially coextensive with and parallel to the suction tube, and has a second longitudinal axis, a proximal opening, and a distal opening; a stylet having a proximal end and a distal end; and a junction point having a proximal opening and a distal opening; wherein the stylet is disposed along the second longitudinal axis and encircled by the guide tube, and urging the stylet through the guide tube along the second longitudinal axis through the junction conduit translates the distal end of the stylet to the distal opening of the junction point. The guide tube may effectively cut the length of the handle member in half. |

1. A suction device comprising:
a suction tube having a first longitudinal axis, a proximal opening, a distal opening, and a suction lumen disposed therebetween; a guide structure having a first guide lumen and a second guide lumen, wherein the first guide lumen is coaxial with the suction lumen; a stylet having a proximal end and a distal end, wherein the stylet is coaxially disposed within the second guide lumen, wherein the second guide lumen includes a proximal end, a middle section, and a distal end, and the middle section includes a substantially U-shape portion and the stylet is longitudinally translatable through the middle section; a junction point intersecting the distal opening of the first guide lumen and the distal opening of the second guide lumen, and axial movement of the stylet through the second guide lumen along the second longitudinal axis through the junction point translates the distal end of the stylet into the suction lumen. |
