An exemplary biopsy device includes (i) an elongated body, (ii) a hollow needle coupled to the distal end of the elongated body, the hollow needle having a channel that spans the length of the hollow needle, (iii) a trigger associated with the elongated body, (iv) a stylet having or associated with a biopsy element, the stylet being disposed within the channel of the hollow needle, operably connected to the trigger, and configured to extend beyond the distal end of the hollow needle and subsequently retract within the channel of the hollow needle, and (v) a spring mechanism operably connected to the trigger such that the spring mechanism compresses in response to operation of the trigger, extending the biopsy element, and is configured to rebound following compression, the rebound causing the biopsy element to retract toward or within the hollow needle.
