Transperineal prostate biopsy device, systems, and methods of use

A method of performing a transperineal biopsy procedure on a prostate of a patient using a transrectal ultrasound probe configured to provide imaging, the patient comprising a perineal access site leading to the prostate, the method comprising:

• imaging the prostate of the patient with the transrectal ultrasound probe, wherein a transperineal biopsy guide is coupled to the transrectal ultrasound probe, the transperineal biopsy guide comprising a mount coupled to the transrectal ultrasound probe, a guide member coupled to the mount and including a rail receiving channel extending a first length between a proximal end and a distal end of the rail receiving channel, and a displacement member including a rail member extending a second length between a proximal end and a distal end of the rail member and a vertically extending member extending from the distal end of the rail member, the vertically extending member including a plurality of needle receiving ports, wherein the rail receiving channel is positioned generally parallel with a longitudinal axis of the transrectal ultrasound probe;
• sliding the rail member within the rail receiving channel so as to position the vertically extending member of the displacement member adjacent the perineal access site of the patient;
• inserting an access needle into the perineal access site of the patient, the access needle supported by one of the plurality of needle receiving ports;
• and
• inserting a needle through the access needle and into a first location of the prostate of the patient.
