Transperineal prostate biopsy device, systems, and methods of use

A method of performing a transperineal biopsy procedure on a patient having a perineum and a prostate, the transperineal biopsy procedure utilizing a biopsy needle, an access needle having a lumen, and a transrectal probe for imaging the prostate, the method comprising:

• attaching a biopsy guide to the transrectal probe via a mount of the biopsy guide, the biopsy guide comprising a guide member and a displacement member, the guide member coupled to the mount and comprising a frame extending upwardly from the mount, the displacement member releasably coupled to the guide member and comprising a needle receiving port, wherein the frame comprises a pair of guides and a channel formed there between, the displacement member configured to slide along the pair of guides and within the channel;
• inserting the access needle through the needle receiving port of the displacement member;
• contacting a distal end of the guide member with the perineum of the patient;
• inserting the access needle into the perineum of the patient with the distal end of the guide member in contact with the perineum of the patient;
• and
• inserting the biopsy needle through the lumen of the access needle and into the prostate to obtain a first tissue sample.

• contacting a distal end of the pair of guides with the perineum of the patient;
• engaging the access needle with the displacement member at one of a plurality of positions above the transrectal probe;
• inserting the access needle into the perineum of the patient using the contact between the distal end of the pair of guides and the perineum as a guide for insertion of the access needle;
• and
• inserting the biopsy needle through the lumen of the access needle and into the prostate to obtain a first tissue sample.
