A tool is disclosed, for taking a biopsy sample, having a needle attached to a syringe, with an opening in the side of the needle, which can be selectively covered by a cannula slidably mounted over the needle. The cannula can be locked into place on the needle, and the plunger of the syringe can be spring loaded to draw a sample into the syringe upon release of a latch. A method is also disclosed for taking a biopsy sample by sliding a cannula over a needle, inserting the cannula and needle into the tissue to be sampled, partially withdrawing the cannula from the needle to expose a lateral opening in the needle, maneuvering a sample of the tissue into the opening, cutting the sample from the tissue, and drawing the sample out through the needle.
