Abstract:
1. A suction device handle to use with a vacuum supply conduit to suction a fluid or tissue, the handle comprising: a hand-grippable body defining a chamber and comprising a distal end configured to support a suction tip; the suction tip including a distal end of the vacuum supply conduit extending within an outer cannula, the vacuum supply conduit being offset from a distal end of the outer cannula by a predetermined distance and configured to couple to a vacuum supply; and a tip connector configured to releasably couple the distal end of the body to the suction tip; wherein the distal end of the body is configured to couple to a proximal end of the outer cannula and the chamber is configured to couple in fluid communication with suction pressure generated at the distal end of the vacuum supply conduit by the vacuum supply; wherein the vacuum supply conduit, when coupled to the vacuum supply, forms the suction pressure (a) at a location directly between an outer wall surface of the vacuum supply conduit and an inner wall surface of the outer cannula, (b) within a portion of the chamber located proximal to the location, and (c) that sucks fluid away from the outer cannula and into the vacuum supply conduit; wherein the vacuum supply conduit is configured to pass through the chamber into the suction tip.
