I had never heard of "Bind Rune" before--so looked it up. Interesting! I did a google search for bindrune help and found this site:

From what I can *guess* the two triangles joined together are the letters "Ng" and "I" and perhaps a "YL" as in Style? - boy...I am not sure! But maybe this site can bhelp you.
eta: at the same site, but a different page, its a bit more helpful, I think.

yours looks a wee bit like the one "Promoting birth" as well as " the one "For Realization of Ambition" or perhaps "to Promote Medical Healing".
