It's formally named, but never called, a hemostatic clamp; properly called a hemostat, often called a stat, and the usual version is never called a clamp as that refers to more specialized instruments. Actually, it's an entire large family of instruments, straight and with varying curve shapes, in widely ranging sizes. I've got them ranging from the usual 5- or 6-inch version to a 14-incher with a mild S-curve for gynecological work, and I'm just a family doc.
Seems to me that the advantage of the pro over the amateur is having the right tools to get something done, and that nothing tops the human body in posing challenges that stimulate constant development of better tools for reaching and manipulating things. Spend a few minutes with a medical instrument catalog some time; it's fascinating to see what's been done, and what subtle variations have been considered worthwhile.
