Robotic Surgery to the rescue

U0204500 Ong Phian Ting Surgery has always been an intimidating experience for those who have to go through it. Just imagine another person standing beside you and cutting you up, not knowing if they will make a mistake in the process. The though alone is enough to send shiver down one’s spine. Fortunately, advance in robotic has come to the rescue of these patient. The Da Vinci Surgical System from Intuitive Surgical Inc is an assistant to a surgeon during surgery. It acts as an extension to the surgeon’s hand. Instead of the surgeon holding the tools that go into the patient’s body, the robotic arms now hold the tools, while the surgeon control the arms through remote control. A video showing the overview of the system could be view at The advantage of the system is numerous to both patient and surgeon. It allows the surgeon to virtually place their hands inside the patient without the need for large incisions. This minimizes the chances of the surgeon making a mistake that could harm the patient or even cause fatality. At the same time, it also helps patient to heal faster due to the smaller incisions. Another advantage is that surgeons can now scale, or ratio, their finger movement to that of the robotic arms. A movement of inches at the console can be scaled down to centimeters in the patient. This gives great control and precision to the surgery. The system also re-introduces precision to an elderly surgeon, who has all those years of experience but has lost some dexterity. The world first surgery using this system could be view at References:

I think it is really great to use this technology to help doctors in performing operations whereby precision is very important. If I’m not wrong, there are already operations performed on patients by doctors several kilometers away through integrating similar if not the same robot with some wireless controlling technology.
It just crossed my mind if in the future there would be a possibility that we can just run programs on this type of robots to do certain operations. Will the doctors be out of job then? But having said this, who will dare to give it a try?

it will be a tuff time for the doctor to get use to this system, because instead of looking trough their eys, and performing the operation with their own hand, the doctor need to do the operation through the camera with the help of mechanical hand, the doctor will loose the sense of touch of the patient actual body, which is the original way they are trained in surgery.

but the idea of smaller incisions is really a idea, less harm, and patients can recover faster.

I think it is quite hard to control the robotic arms, a lot of practice is definitely needed! The video which shows the doctor sewing up the inside of the patient is quite incredible.. i seriously think the doctor has to be really skilled in operating this robot, otherwise accident could happen.

Use of machines in the medical field have always been present, nonetheless, with increasing sohpistication, such as the introduction of medical robotics. However, the role of such medical robot are still assistive in nature. They serves as a means to assist the doctor in the diagnosis and treatment of the patients.

The Da Vinci Systems are able to improve the surgical precision of doctors greatly, and its ability to operate through extremely small incision can greatly reduce the debilitating nature of the treatments. However, an important point is that they are not autonomous. The decision making process are still carried out by the doctors. hence, their role for now are still restricted to being assistive. The leap to robots replacing human doctors may still yet be a large one.

It is a very interesting reach area to do surgical with the help of robot, and could minimize the probability of the surgeon making a mistake to patients. But my doubt is, at current stage, if the robot technology is mature enough to use it in such a danger zone where any small mistakes could cause a serious problem.

The ability to scale the finger motion of the doctors to the movement of the robotic arms is great, since it will potentially minimise any human errors due to unsteady arms and will allow doctors to easily perform delicate operations. However because the doctor is controlling the roctor remotely, the doctor will have to rely on images from his monitor screen. As a result, the doctor might potentially lose some of his depth perception, which will in turn increase the risks involved in the operation

In my opinion this approach seeks to improve that lion's share of surgeries, particularly cardio-thoracic, that minimally invasive techniques have so failed to supplant.
