More Information
Summary:A needle holder for a tissue sampling device, such as a biopsy gun, may include a receptacle, a cradle within the receptacle, and a cover that interacts with a lock on a biopsy needle set when the cover is closed. The biopsy needle set may include a needle hub that carries a proximal end of a needle, a cannula hub that carries a proximal end of a cannula positioned over a portion of the needle, and a lock. The lock may have a locked arrangement that holds the needle hub and the cannula hub longitudinally in place relative to one another, as well as an unlocked arrangement in which the needle hub and the cannula hub may be moved toward and/or away from one another, enabling the needle to move through the cannula. Methods for obtaining samples from a body of a subject are also disclosed.
