A visual-assisted insertion device for ensuring accurate and repeatable needle insertion into the human body regardless of skill or training. A user of the visual-assisted insertion device may accurately perform inter-organ needle insertion by determining a desired needle-insertion point on an ultrasound display screen, wherein the insertion point and angle of the needle is automatically calculated and mechanically adjusted to correspond to the desired needle-insertion point. Accordingly, unsuccessful inter-organ needle insertion is minimized through a handheld, visual-assisted insertion device which simplifies the inter-organ needle insertion process.
