A protoplaser was a medical device used in wound treatment. Anabolic protoplasers were specialized versions of protoplasers.
In a delusion created by Commander William T. Riker's mind while he was held captive on Tilonus IV, Doctor Beverly Crusher ordered for an anabolic protoplaser to be used in the treatment of a crewmember who had been injured by an exploding plasma torch. (TNG: "Frame of Mind")
- Information about Eckridge that mentioned the protoplaser was visible in an okudagram graphic, not from dialog or from an explicitly seen prop.
- Detailed drawings of a protoplaser device (an "anabolic protoplaser") seen in the Star Fleet Technical Manual match the prop seen used by Christine Chapel on Spock following his disastrous mind-meld with V'ger in Star Trek: The Motion Picture, and by Leonard McCoy on Peter Preston in Star Trek II: The Wrath of Khan.
