Abstract
Various surgical instruments for laparoscopic procedures are provided for aspirating and retracting a hollow organ such as a gallbladder. The surgical instruments include a needle body and an anchor coupled to the needle body. The anchor is adapted and configured for engaging and retracting the hollow organ, and can be held and deployed from within the needle body or from an outside surface of the needle body. The needle body defines an aperture for permitting aspiration of contents of the hollow organ.
