Cutting a curve-pattern with a curve like a wirecutter?

Hi, I generated a pattern with curves and I would like to use another curve to cut all these pattern curves now. Is there a simple way of doing this? I would like to use the highlighted curves as if it was a wire cutter basically. and it would be perfect if I could at once get rid of the pattern curves that lie outside of the cutting-curve.
