Abstract
A biopsy device comprising: a cannula comprising an elongate cannula body extending between a cannula distal end and a cannula proximal end to define a lumen, wherein the cannula comprises a cutting portion at the cannula distal end; a stylet comprising an elongate body having a stylet distal end and a stylet proximal end, the stylet being slidably disposed within the lumen, wherein the stylet comprises a tissue sampling portion. The tissue sampling portion is formed by a notch in the body of the stylet at or near the stylet distal end. The biopsy device further comprises an actuator assembly, the actuator assembly arranged to move the cannula relative to the stylet between a retracted position in which at least part of the tissue sampling portion is exposed and an extended position in which the cannula at least partly surrounds the tissue sampling portion. The actuator assembly comprises a cannula actuator moveable between a primed configuration and an actuated configuration to move the cannula between the retracted position and the extended position. The biopsy device further comprises a selective coupling mechanism arranged to provide a selective coupling between the actuator assembly and one or both of the stylet and the cannula.
