There are two different types of robots that can be used in surgery, which are passive and active. According to Gerhardus, “A doctor controls a passive robot” (245). Doctors use passive robots to help them be more accurate, precise, and safer during surgery. Gerhardus states that a passive robot is mainly used to perform cardiac surgical procedures (245). There are advantages and disadvantages to using robot-assisted surgery. Surgeons, who are willing to use robots during surgery, will improve the quality of care for their patients, reduce the pain experienced by the patient, and the patient's recovery will be much faster (Gerhardus 245). For example, a patient whose operation was performed using a robotic system will recover in about a week; another patient who underwent the same surgery, but whose surgeon did not use the robotic system, will recover in about two weeks, or sometimes longer. Additionally, according to Gerhardus, “robot-assisted surgery reduces the rate of occurrence of bacterial infections and blood transfusions” (250). According to Gerhardus, the downside of using robots to aid in performing surgeries is that each medical facility will have to spend a significant amount of money to ensure that workers are educated and trained in the use of this type of technology when performing a surgical procedure (249). . Although robot-assisted surgery has a drawback, it is only one
