Zusammenfassung:A biopsy device includes a needle extending longitudinally from a proximal end to a distal end and including a channel extending therethrough and a stylet extending through the channel of the needle and including a coil at a distal end thereof such that rotation of the stylet relative to the needle moves the coil from a closed configuration in the channel to a tissue collecting configuration in which the coil extends distally past the distal end of the needle to be inserted into a target tissue.
