Abstract
A template grid which attaches to an ultrasound stepper of a transrectal ultrasound unit providing transperineal guidance and support through adjustable angle apertures allowing for accurate targeting of a medical implant such as a needle to its intended target such as for purposes of perirectal spacer placement. The rotational apertures allow for free adjustable changes in the trajectory of a medial implant such as a needle to its intended target while providing stability and support to the medical implant itself. The template grid, in addition, contains fixed apertures for placement of a medical implant such as a needle into the substance of the prostate gland positioned to avoid inadvertent passage through the urethra and rectum.
Claims8
A grid system configured to attach to an ultrasound stepper unit, wherein the grid system comprises:
- a front surface;
- fixed apertures arranged laterally with respect to a midline of the front surface which facilitate a stable passage of a first medical implant into the prostate gland along a fixed angle trajectory of the first medical implant relative to the front surface;
- rotational apertures arranged along the midline of the front surface which facilitate a stable passage of a second medical implant into the perineum to an intended target and which allow a variable angle trajectory of the second medical implant with respect to the front surface,
- wherein the first medical implant and the second medical implant each include at least one of a needle or a catheter.
