Abstract
Among other things, there is disclosed a biopsy needle system in which the needle is capable of obtaining more than one length of sample. Generally, the needle includes an inner stylet, an outer cannula, and a handle connected to the stylet and cannula. The stylet has a notch that is extendable from the cannula to accommodate a tissue sample. An insert member is provided for attachment to the handle to make the amount of exposed notch smaller. Consequently, when the insert member is not attached to the handle, the needle can obtain a larger sample of tissue, and when the insert member is attached to the handle, the needle can obtain a smaller sample of tissue.
