Chakra Scalepel requires an incredible amount of concentration, control and precision to use. However, it's use isn't necessarily advanced. If used for strictly medical purposes, it's not really out of place on a Nara Chuunin. However, it'd be utterly useless in combat. Her Nara has no real taijutsu capabilities, no muscle memory, no close range training. Chances are, in close quarters combat, the Nara wouldn't even be able to use Chakra Scalpel, let alone fight with it. The only shinobi seen doing so was Kabuto, and as we know he might as well have been an S-Class ninja.
