The Marvelous Medical Robot

What kind of “marvelous” surgery was this? In fact, Beaver underwent an eye surgery performed by a robot. The doctor operated the robot through a touchscreen, guiding a fine needle into the eyeball and monitoring the surgery process through a microscope, removing a membrane inside the patient’s eyeball that is only 0.01 millimeters thick.

Since the 1980s and 1990s, machines have entered the surgical field, becoming a common phenomenon. Nowadays, surgeries are not entirely performed by doctors’ hands but rely on high-precision instruments.

Current laser scanning and microscopic technologies allow people to examine retinal diseases at a microscopic level, which exceeds the physiological limits of human hands. The use of robotic systems has opened a new chapter in the development of eye surgery, making previously impossible surgeries feasible.

Will robotic surgeries be increasingly promoted in the future? Or will robotic surgeries replace human-operated surgeries?

Robots still cannot replace doctors. Why? First, treating illnesses is not simply a matter of surgical skills; ultimately, it is the doctor’s clinical thinking that makes the final decision, which machines cannot replace. What robots can assist doctors with is, for example, when a doctor has rich experience but due to age, fatigue, or the precision of the tissue, they cannot achieve 100% accuracy. In such cases, robots can play to their strengths.

Currently, there are three main applications of surgical robots. One type is the Da Vinci robot, which completes many complex surgeries in minimally invasive procedures, enhancing precision and surgical outcomes under the control of the doctor. The second type is radiation robots, which focus on precision, better targeting the lesion area and reducing the radiation dose due to hand tremors or misalignment. In this process, data tells us that the precision of these robots can reach sub-millimeter levels, allowing for very precise targeting of the areas to be irradiated, reducing damage. The third type is auxiliary surgical systems that help make surgeries more precise and improve surgical outcomes through navigation devices.

Robots are not strangers to the healthcare industry. A large number of robots have been used in various physical therapies, and some robots have been used to help train doctors in a series of treatments and surgeries.
