A laparoscopic surgery machineWhen we talk about robots performing tasks of human, we talk about future. But the use of robots in surgery is already a reality. The developments of technologies have brought various robotic devices into the medical field and these advanced robotic devices have been performing as a great assistant in a surgery room for today. With these robotic systems, the operation has become much less invasive but however, due to some disadvantages of these systems, surgeons are still cannot being replaced. Minimally invasive surgery is a broad concept including many common procedures that existed prior to the introduction of robots, such as gall bladder excisions. It refers to procedures that avoid long cuts by entering the body through a small entry [7]. However, surgeons can perform this procedure by using long handled surgery equipments and the guidance of viewing equipment such as endoscope; therefore it is not a necessary to use robots to do that. But yet, it does not mean robots are then do not categorised under minimally invasive surgery.

Robot-assisted surgery system can be divided into 3 kinds which are supervisory-controlled system, telesurgical system and shared-control system.

First, supervisory-controlled system is a system that allows the robots to perform tasks individually which will act according to the computer programme where the surgeons inputs into them earlier. Next, the telesurgical system which is also known as remote surgical requires the direct involvement of surgeons to conduct the robot’s arm rather than allowing it to perform surgery procedures by itself. Because the robot is still technically performing the procedures, so it is still considered under the subgroup of robotic surgery. The third system will be shared-control system. In this system, it requires the most involvement of surgeons. The surgeon carries out the procedure with the use of a robot that offers steady-hand manipulations of the instrument. This enables both entities to jointly perform the tasks [7]. Overall, the main difference between these 3 systems is the degree of interaction between the surgeons and the robots during the procedures. [8]

Although the robot-surgeons can perform as a great assistant in surgery rooms, however there is nothing to be one hundred percents safe, including these robots. Mechanical devices including robots have the potentials to be malfunction and contravened the concept of minimally invasive surgery, or even worse, causing harm to the patients. Hence, safety of using these equipments has been questioned. Manufacturers have endeavoured to reduce the risks of malfunctioning of robots by installing related safety features. Nevertheless, these safety measurements have caused these robots increase in cost, making them unaffordable.
