Transperineal prostate biopsy device, systems, and methods of use

A transperineal biopsy guide configured for use with an access needle and a transrectal imaging probe adjacent a patient's perineum, the access needle including a proximal end hub, a distal sharp end opposite the proximal end hub and a longitudinal axis extending between the proximal end hub and the distal sharp end, the access needle sized to receive a biopsy instrument therethrough, the transrectal imaging probe including a proximal end, a distal end and a longitudinal axis extending between the proximal end and the distal end, the transrectal imaging probe configured to provide imaging in an imaging plane of the transrectal imaging probe, the transperineal biopsy guide comprising:

• a mount attachable to the transrectal imaging probe between the proximal and distal ends of the transrectal imaging probe;
• a guide member extending from the mount and including:
• a first side comprising a first distal member and a first surface extending proximally from the first distal member;
• a second side comprising a second distal member and a second surface extending proximally from the second distal member;
• and
• a gap between the first distal member and the second distal member;
• and
• an access needle support structure securable to the guide member in a distal position that inhibits vertical displacement and distal displacement of the access needle support structure relative to the guide member while permitting disengagement from the distal position via proximal movement of the access needle support structure relative to the guide member, the access needle support structure configured to support the access needle at a plurality of heights relative to the mount with the access needle being at least partially located in the gap when the access needle support structure is secured to the guide member in the distal position, the access needle support structure comprising first and second members extending laterally therefrom, the first and second members being on opposite sides of the access needle support structure.
