Руководство по хирургии
All surgery requires the set of medical tools in the Operating Theatre, along with a table (a surgical table gives no negative results). For the most part, only medical doctors and the Chief Medical Officer can perform advanced surgery.
Surgical Tools
Surgical tools can be found in surgery and robotics. Additionally, cargo can make them with their autolathe. It is best to keep surgical tools in their proper places so your fellow crewmembers can use them when they need them. The following are the standard surgical tools most doctors will need:
MMI (For Robotics)
Surgical drill
Scalpel
Circular saw
Hemostat
Cautery
Retractor
Drapes
How to set internals
To set internals and make your patient sleep you need to first remove any item from their back. Once done you need to put a breath mask on them and then put the anesthetic tank onto their back. Once it is on their back you can put them on internals by clicking "set internals" on the same menu you used to put the tank on their back. Once done your patient should fall asleep. Remember to use a proper anesthetic mixture, as pure N2O will suffocate the patient.
