At a shallow level, the original intentions of human-made robots may be two, one is liberating human labor, and the other is helping human beings to do something that cannot be done by human beings. The former has been developed for many years. It has developed very smoothly both industrially and commercially. Many similar machines can be seen on the market; while the latter represents a kind of sophisticated technology, and the benefits to humans seem to It is limitless, such as medical treatment.
We have seen many reports on medical robots before. Robot surgery is not new. However, this time robot surgery was not just “liberating the labor force†but it was a medical breakthrough. Recently, British surgeons and robots worked together to perform an operation. Unlike robot surgery that we heard in the past, this robot was operated in the eye of a person with a diameter of less than 24 mm. The robot succeeded from the eyes. A layer of only 0.01 mm thick was removed from the retina. This is also the first time in human history to use robots for eye surgery, and robots have once again achieved a breakthrough in the field of "precision surgery."

The patient was a local priest in Oxford, England named William Beaver. He was 70 years old. Before the operation, he had a film on the retina of his right eye and caused retinal damage. A small hole appeared. . This film made Beaver very annoyed because everything in his eyes was distorted, as if the entire world had become a magic mirror.
After inspection, Beaver needed to pay close attention to removing this film, otherwise it would have further impact on the eyes. However, the related surgery to remove this membrane is extremely difficult because the thickness of this membrane is only 0.01 mm. In the position of the retina, how to remove it does not cause damage to the retina.
Beaver's chief physician is Professor Robert MacLaren of the John Radcliffe Hospital in Oxford, England. The professor said that in order to ensure the success rate and stability when using traditional artificial surgery to treat such conditions, the patient's heart rate will be manually intervened. And, according to past experience, this kind of surgery will touch the retina more or less, causing bleeding.
After research, Professor MacLaren decided to use a robot to complete the operation. He believes that the robot can complete beyond the accuracy that human hands can achieve. With a robot, the whole process is much simpler. The surgeon only needs to hold the joystick and use the touch screen to control the robot. The coworkers can monitor the retina and the operation dynamics from the microscope.
The benefits of using robotic surgery in addition to accuracy, but also in terms of stability, even if the doctor moves the joystick when the movement is very large, reflected in the robot will become very subtle, greatly reducing the doctor's trembling caused by ACCIDENT.

The surgery was very successful. Professor MacLaren said that current laser technology and microscopes allow us to observe retinal diseases at the microscopic level, but many of the cases we see far exceed the physical limits that human hands can manage, so the treatment The difficulty is very high. The use of robot-assisted approach to surgery will become a future trend.
PreceyesThe surgical robot (precisely speaking a control arm) is a company called Preceyes, formerly a research institute at the Eindhoven University of Technology in the Netherlands. The company was incorporated in 2011. At present, the company has developed the PRECEYS surgical system, which is specifically aimed at high-precision small-space surgical procedures (currently only related to ophthalmology).
Their robot system also conducts experiments on relevant ocular gene therapy and stem cell therapies at various medical experiment centers around the world (similar to the method of using a robot to insert fine needles into the retina to inject drugs or other therapeutic fluids. The duration of this injection process Speaking for up to 10 minutes, it is almost impossible for doctors to perform tasks that are almost impossible to complete without errors. If this step succeeds again, it will mean setting a precedent for the brand-new retinopathy therapy.) The system has already had many successful clinical trials. It will conduct CE certification before the end of this year, and will fully promote the system in 2018.
Preceyes announced its entry into the field of ophthalmic surgical robots in 2014 and has been conducting research in this area. In November 2014, one of their research projects, "VR Surgical Robots," received the best innovation award from the European Society of Retina Experts (EURETINA).
In 2015, Preceyes CMO Marc de Smet published a paper claiming that high-precision robots will bring revolutionary results to future eye surgery, and the company’s research has made major breakthroughs.
This year, Preceyes replaced a new CEO, Perry Van Rijsingen. Rijsingen had served as CEO of Philip's “medical investment department†for several years. He has extensive medical experience. The company’s appointment as CEO also aims to make him For the company's medical robot research and development planning effective strategy. Â
futureFor this unprecedented robotic eye surgery, related industry sources stated:
Surgical robots will surely become the main force of precision surgery in the future and will provide more efficient and safe surgical services for humans.
Mankind itself is an unreliable creature. No matter how high his level of surgery is, a doctor will be affected by various factors such as fatigue and psychological factors. Therefore, when the negative factors exceed the limits of the body, the movement will be deformed. The patient is in danger. The surgical robot provides protection for the stability of the surgery.
In addition to ensuring safety, it can greatly increase efficiency. Currently, a prestigious surgeon often performs a lot of operations a day, and most of the patients will choose these famous doctors for a long time. The popularity of robots will make this easier. For example, in the future there will be the emergence of remote network surgical robots, so that more civilians will not be able to seek medical care for thousands of miles, and hospitals near their homes can treat diseases that cannot be resolved under local medical conditions. This is also a boon for those who want to seek medical advice or for emergency patients. .
