It is believed that many people have already understood that robots operate on humans. The famous “hand of Leonardo da Vinci” – Leonardo da Vinci surgical system has become a good helper for surgeons. The reporter of Yangzi Evening News learned from Nanjing Brain Hospital that “ROSA” robot, the little partner of “Da Vinci Robot”, also came to Nanjing recently. This robot can help doctors operate on human brain, with accuracy and speed far exceeding traditional surgery. This is the first “ROSA” robot introduced in Jiangsu.

Colorful, surgeons call it “Princess”

The functional neurosurgery experts in our hospital operate with the assistance of rosa
ROSA is a multi-functional robot from France. The full English name is (Robot of Surveillance Assistant). Different from the image of ordinary robots, ROSA has soft lines and gorgeous colors. Its whole body is covered with rose colored ribbons. Neurosurgeons affectionately call it “Princess ROSA”. The little princess is not arrogant at all. She works quickly and beautifully. Its arms are free and flexible, and its hands are “fast and accurate”. Zhang Rui, director of functional neurosurgery and chief physician of Nanjing Brain Hospital, revealed that ROSA’s mechanical arm is equipped with a sensing device that can automatically track the patient’s position. “It integrates preoperative planning software, navigation and tracking functions, robot assisted device positioning and operating system, and advanced visualization functions.” ROSA can quickly capture and locate the lesions in the patient’s brain with an error of less than 1mm. However, in traditional surgery, there is a complex process to locate the brain lesions. Doctors often need to use X and Y field operations on the operating table to obtain the precise location of the lesions. And every time you look, you need to adjust the patient’s brain posture and recalculate. “It can be said to do math problems while performing surgery.” Director Zhang Rui smiled. Since Princess ROSA “arrived”, the problem of precise positioning has been solved, and doctors only need to focus on the operation itself. “This greatly shortens the operation time and is at least twice as fast as the traditional operation. The patient’s trauma is smaller.”

Eight electrodes were implanted in the brain, and the operation was shortened to 2 hours

After coming to Nanjing, ROSA has assisted experts in functional neurosurgery in the brain hospital to perform many operations. Ms. Wang, a 32 year old epileptic, had received stereotactic electrode implantation with the help of ROSA robot a few days ago. Director Zhang Rui said that epilepsy, commonly known as “epilepsy” or “epilepsy”, is a chronic disease that causes transient brain dysfunction due to sudden abnormal discharge of brain neurons. About 30% of drug-resistant patients need surgery to relieve their pain, and Ms. Wang is one of them. When Ms. Wang was 17 years old, she was diagnosed with epilepsy. During the seizure, she frothed at the mouth and twitched all over. As the course of the disease continued, her symptoms became more and more serious. It was time for surgery. The electrode implantation operation is to implant the electrode into Ms. Wang’s brain lesion, adjust the electric wave and restore the brain function. The surgery requires high accuracy of the lesions, and ROSA has the opportunity to show its skills. The expert worked out the operation plan through the preoperative planning software, and ROSA called navigation to track and locate the 8 lesions in Ms. Wang’s brain. “Through minimally invasive surgery, 8 electrodes were rapidly implanted into 8 lesions.” Director Zhang Rui said that the operation time was shortened to 2 hours, while it would take half an hour for traditional surgery to implant an electrode. “Precise, minimally invasive and efficient, this is the arrival of ROSA robot, which brings significant changes to brain surgery.”

It is also a good helper to equip the brain with a pacemaker

Deep brain stimulation, commonly known as brain pacemaker (DBS), is a landmark new technology in surgical treatment of Parkinson’s disease. This technology can significantly improve the symptoms of movement retardation, muscle stiffness or tremor of Parkinson’s patients, and can also significantly reduce the side effects of taking drugs. The operation is very difficult and golden. ROSA robot has assisted Zhang Wenbin, deputy director of functional neurosurgery and chief physician of Nanjing Brain Hospital, to perform DBS operation for two Parkinson’s patients. Zhang Wenbin, the chief physician, explained that DBS therapy is mainly to implant brain pacemakers into the patient’s brain, stimulate some nerve nuclei in the deep brain, correct abnormal brain electrical circuits, and reduce these neurological symptoms. “The more accurate the implantation of brain pacemaker, the better the effect. The arrival of ROSA has greatly improved the accuracy.” The reporter learned that ROSA will also be used in tumor interstitial chemotherapy, brain tumor localization and biopsy, hematoma drainage, cyst drainage and other fields in the future.
Are ROSA robots at risk
Robots operate on the human brain. It sounds terrible. Is this operation risky? Zhang Wenbin explained that ROSA is a functional auxiliary robot whose main function is precise positioning. The brain surgery is still completed under the guidance of doctors, so ROSA will not damage the brain, on the contrary, it greatly improves the surgical accuracy.
Is the surgery expensive
How much will the cost of surgery increase after ROSA joins? Director Zhang Rui said that this is the first ROSA robot introduced in Jiangsu, and the price department has not yet approved the charging standard. At present, ROSA robots do not charge extra. The future charges shall be subject to the provisions of the price department.
