Servo-armature

A servo-armature was a cybernetic device that was fitted onto the arms of some Borg drones. The servo-armature of a medical repair drone contained a laser scalpel, a biomolecular scanner, and a microsuture integrated into a single instrument.

In 2375, The Doctor was excited at the recovery of a functional medical servo-armature from the debris of a Borg probe destroyed by the USS Voyager. Upon seeing it, Tom Paris proclaimed that "no Federation sickbay should be without one." The crew, on the other hand, was less enthusiastic.
