A field surgeon ring
A field surgeon ring was a type of ring that was typically used by medics. Following the Battle of Yavin, one such ring was presented on Tatooine to a medic. The giver was Nillika, who served as Administrator of the Mos Eisley Medical Center. This was in recognition of the medic's aid in treating those injured during a conflict in Mos Eisley. The conflict involved Lady Valarian's guards and the thugs working for Jabba the Hutt.
The Field Surgeon Ring appeared as an in-game item within the 2003 video game Star Wars Galaxies. This game was a massively multiplayer online roleplaying game created by Sony Online Entertainment and distributed by LucasArts. The game was shut down on December 15, 2011. The ring was introduced to the game with the "Publish 25" update, also known as the "New Game Enhancements," which went live on November 15, 2005. It served as a reward for the "Caught in the Crossfire" quest, specifically for players who chose the Medic profession. Wearing the ring provided a small boost to the player's constitution stat.
