Transperineal prostate biopsy device, systems, and methods of use

Abstract

A transperineal biopsy guide including a guide member and a displacement member supported by the guide member. The guide member may be configured to operably couple with the transrectal probe and may include a distal end, a proximal end opposite the distal end, and a length extending along a longitudinal axis between the distal and proximal ends. The displacement member may be configured to support the access needle and displace the access needle along at least a portion of the length of the guide member between the distal and proximal ends. The access needle may extend into the subcutaneous tissue when the access needle is displaced to the distal end.

What is claimed is: 
     
         1 . A method of performing a transperineal biopsy procedure on a prostate of a patient using a transrectal ultrasound probe configured to provide imaging in at least a sagittal imaging plane, 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 including an adjustable fastener 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, and a displacement member including a rail member extending a second length between a proximal end and a distal end, and a vertically extending member coupled to 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 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 through one of the plurality of needle receiving ports and into the perineal access site of the patient, the access needle positioned within the sagittal imaging plane; and   inserting a needle through the access needle and into a first location of the prostate of the patient.
