Transperineal prostate biopsy device, systems, and methods of use

1. A biopsy guide configured to couple with a transrectal probe and for use in guiding a needle in a transperineal prostate biopsy procedure, the transrectal probe configured to provide imaging in at least a sagittal imaging plane, the biopsy guide comprising:

a guide member configured to operably couple with the transrectal probe and comprising a guide body including a distal end, a proximal end opposite the distal end, a length extending between the distal and proximal ends, a base platform extending a portion of the length, a first extension member extending upwards from the base platform on a first lateral side thereof, a second extension member extending upwards from the base platform on a second lateral side thereof, a first guide member coupled to the first extension member and extending the length and comprising a first planar top surface and a first distal member at a distal termination thereof, and a second guide member coupled to the second extension member and extending the length and comprising a second planar top surface and a second distal member at a distal termination thereof, wherein a distal portion of the first and second guide members overhangs the transrectal probe by distally being positioned beyond a distal edge of the base platform when the guide member is coupled to the transrectal probe; and

a displacement member supported by the guide member, the displacement member comprising a central vertically extending member having a plurality of needle receiving ports therein, and a planar member coupled to the central vertically extending member and having a planar bottom surface that is configured to slide on the first and second planar top surfaces of the first and second guide members, respectively, up until the displacement member is in a distal position abutting the first and second distal members which prevent further distal movement of the displacement member, wherein, in the distal position, the displacement member is positioned beyond the distal edge of the base platform.

2. The biopsy guide of claim 1 , wherein the guide member is configured to operably couple with the transrectal probe via a fastener.

3. The biopsy guide of claim 2 , wherein the distal portion of the first and second guide members that overhangs the transrectal probe when coupled thereto extends longitudinally beyond a boundary surface of the fastener.

4. The biopsy guide of claim 1 , wherein the planar member coupled to the central vertically extending member extends laterally outward from a plane extending through the plurality of needle receiving ports.

5. The biopsy guide of claim 1 , wherein the plurality of needle receiving ports are each sized to receive an access needle therein, the access needle configured to receive the needle therein.

6. The biopsy guide of claim 1 , wherein the displacement member further comprises a pair of tab members coupled to and extending laterally outward from the central vertically extending member, the pair of tab members positioned vertically along a height of the plurality of needle receiving ports.

7. The biopsy guide of claim 1 , further comprising the needle.

8. The biopsy guide of claim 1 , wherein a length of the displacement member is shorter than the length of the guide member.
