1. A biopsy device comprising: (a) a handpiece adapted for grasping and manipulating with a single hand; (b) a needle extending distally from the handpiece; (c) a cutter movable relative to the needle to sever tissue received in the needle; (d) a first finger operated control disposed on an upper surface of the handpiece; (e) a second finger operated control disposed on a first side surface of the handpiece; and (f) a third finger operated control disposed on a second side surface of the handpiece; wherein each of the first, second and third controls are positioned for operation by fingers of the hand grasping the handpiece; wherein the biopsy device is operable to receive a user input from at least one of the first, second, or third controls, wherein each of the first, second, and third controls are configured to transition between a first and second state, wherein the biopsy device is operable to transition any one of the first second, or third controls to the first state, wherein the biopsy device is operable to determine which of the first, second, or third controls is transitioned to the first state based on the user input, wherein the first state corresponds to activation of the any one of the first, second, or third controls to actuate movement of the cutter through an automatic sampling sequence that advances and reverses the cutter; and wherein the biopsy device is operable to transition any two of the first, second, or third controls to the second state such that only one of the first, second, or third controls is capable of actuating the movement of the cutter through the sampling sequence, wherein the biopsy device is operable to transition the any two of the first, second, or third controls to the second state based on the user input.
