2-1B surgical droids were advanced medical droids popular across the multiverse to those that could afford them. The 2-1B series was humanoid, with many of its internal components visible through a translucent torso sheath. A 2-1B model's arms featured exceptional joint articulation with precision-crafted servogrip pincers at the end of each limb. Sometimes, in certain operations, these pincers could be removed and replaced with multiple arm attachments containing various medical tools and software packages, including hypodermic injectors and cutting saws.
