A medical repair drone was a type of drone utilized by the Borg Collective.
Magnus Hansen classified certain types of drones as "medical repair drones" while studying the Borg aboard the USS Raven. "Needle Fingers" was one such drone.
The servo-armatures of medical repair drones include a laser scalpel, biomolecular scanner, micro-suture, and dermal regenerator among their inventory of tools. These drones conduct repairs on the biological and cybernetic components on damaged drones. (VOY: "Dark Frontier")
