Precision machining robots are not the main application of robots in the medical world.
With the continuous development of artificial intelligence and robotics, the technology has given rise to many new industries of medical robotics. Medical robotics is a new cross-research field integrating many disciplines such as medicine, robotics, artificial intelligence, biomechanics, materials science, and computer graphics and imaging, and has become an international research hotspot in the field of robotics.
Introduction of surgical robots:
The number of medical robotic surgeries has reached 650,000 in 2016 from 25,000 in 2005. 80% of prostatectomy surgeries are done by robots. A surgical robot is a combination of devices.
It is usually assembled from an endoscope (probe), surgical instruments such as knives and scissors, a miniature camera and a joystick, and other devices.
According to foreign manufacturers, the working principle of the surgical robot currently in use is to carry out surgical operations through wireless operation, i.e., the doctor sits in front of the computer monitor, carefully observes the lesion situation in the patient's body through the monitor and endoscope, and then accurately removes the lesion (or repairs it) through the scalpel in the robot's hand.
The robot's most important feature is that it has dexterity that people don't have, based on:
1) a tremor filtering system that filters out the surgeon's hand tremors;
2) a motion reduction system that proportionally (5:1) reduces the surgeon's range of motion.
Currently, surgical robots are most widely used in orthopedic surgery, neurosurgery, endoscopic surgery, and interventional medicine.
