Abstract:
A biopsy device comprising:a housing; a cannula slidably extending from the housing through an opening; a stylet slidably positioned within the cannula; a stylet actuator associated with the stylet to retract the stylet within the housing; and, a cannula actuator associated with the cannula to retract the cannula within the housing, the cannula actuator juxtaposed the stylet actuators; wherein the stylet actuator and the cannula actuator are actuable in three sequences: a first sequence wherein the cannula actuator is actuated independently of the stylet actuator and subsequently the stylet actuator is actuated; a second sequence wherein the cannula actuator and the stylet actuator are actuated simultaneously; and, a third sequence wherein the stylet actuator is actuated and engages the cannula actuator such that the cannula actuator is actuated simultaneously with the stylet actuator.
