Why is this surgical robot called "Da Vinci" popular recently?

my country completed the first da Vinci robot surgery for oropharyngeal cancer; the robot "Da Vinci Hands" gave birth to a revolution in gastric cancer surgery; Zhejiang University Children's Hospital has performed more than 100 da Vinci robot surgeries in 4 months...the latest one is called "Da Vinci" The robot is on fire.

Who is Leonardo da Vinci? The most famous one is one of the three masters of the Renaissance and created the immortal masterpiece "Mona Lisa". There is a robot with the same name as this person, but instead of painting, he performs surgery. He is an active member of the medical community and may be expected to create a textbook-level "surgical work."

Named after the art master Leonardo da Vinci

The da Vinci surgical robot is an advanced robotic platform with a surgical system. It was originally based on the robotic surgical technology developed by the Massachusetts Institute of Technology. Its design concept is to perform complex surgical operations using minimally invasive methods.

The reason why it is called Leonardo da Vinci is indeed derived from the art master-Leonardo da Vinci.

Leonardo da Vinci himself became a legend in the art world thanks to his painting of the Mona Lisa.

In fact, his research on human anatomy is commendable.

According to statistics, Leonardo da Vinci dissected and observed more than 30 human corpses in his life, and drew a large number of human anatomy diagrams. After years of baptism, it is still a model for the medical community to study the mysteries of the human body.

Relying on his in-depth exploration of the human body structure, Leonardo da Vinci designed a humanoid machine in 1495, and is therefore considered the inventor of the world's first robot.

Yes, that’s how the da Vinci robotic surgical system got its name.

DaVinci robot sews up grape skins

The Da Vinci robot consists of three parts: the surgeon's console, the bedside robotic arm system, and the imaging system. In January 1999, the Da Vinci robotic surgical system obtained European CE market certification, marking the birth of the world's first true surgical robot; in July 2000, the Da Vinci robotic surgical system obtained the U.S. FDA approved, becoming the world's first robotic surgical system that can be officially used in the operating room. It has been widely used in general surgery, thoracic surgery, urology, obstetrics and gynecology, head and neck surgery, cardiac surgery, etc. for adults and children. segmented areas.

Showing off one's talents in operating rooms of various departments in our country

In 2006, my country introduced the first da Vinci surgical robot. Since then, surgeons have had a solid “right-hand man”.

In August this year, head and neck surgeons from the Eye, Ear, Nose and Throat Hospital of Fudan University used the da Vinci robot for the first time to perform oropharyngeal cancer surgery. The patient who underwent the operation was a 73-year-old patient with recurrent oropharyngeal cancer. He was discharged from the hospital only three days after the operation. The Da Vinci surgical robot is characterized by minimally invasive surgery, so the damage caused during the operation is very small, and the bleeding is also very small. It is reported that the patient's bleeding does not exceed 10 milliliters, which is only equivalent to one tablespoon.

In the same month, the da Vinci robot surgery at the Children's Hospital of Zhejiang University School of Medicine successfully performed its 100th operation. The isolated lung of a 7-month-old baby was successfully removed and he could be discharged from the hospital 3-5 days after the operation. Professor Shu Qiang, Secretary of the Party Committee of the Children’s Hospital of Zhejiang University and a well-known cardiothoracic surgery expert, pointed out in an interview with the media that children’s tissues and organs are smaller than adults, and blood vessels and tubes are thinner, which puts forward higher requirements for the accuracy of surgery. Da Vinci surgery The robot has a 360-degree rotatable mechanical arm and a shock-proof function. It has the characteristics of small trauma, fast recovery, complete resection, and few complications.

With the assistance of robots, for patients, it can reduce postoperative pain, and for surgeons, it can help reduce the fatigue caused by standing for long periods of time during surgery.

In the process of continuous upgrading, the da Vinci robot is increasingly used in surgeries in major hospitals and different departments. The Da Vinci robot is currently the most advanced surgical robot in the world and has been favored by major hospitals at home and abroad.

Da Vinci can easily operate on the operating tables of major hospitals. How strong is its ability?

Official information shows that the da Vinci system can translate the surgeon's hand movements at the console in real time, bending and rotating instruments while performing surgery. These tiny wrist joints can move like a human hand, but with a greater range of motion. The da Vinci Vision System also provides a highly magnified 3D high-definition view of the surgical area, allowing surgeons to use instruments to operate through one or several small incisions.

At present, the Da Vinci robot has been upgraded to the fourth generation and has recently been officially put into use in hospitals such as Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine and Chengdu Third People's Hospital.

Domestic surgical robots need to break through technical constraints

As the application scale of da Vinci robot continues to expand, my country's surgical robots have entered the blue ocean era.

In July this year, Tianzhihang, the first domestic orthopedic surgical robot company, successfully IPOed on the Science and Technology Innovation Board. According to the "2019 China Robot Industry Development Report" released by the China Electronics Society, among medical surgical robot companies, Tianzhihang, Boshi Co., Ltd., and Miaoshou Robotics have jointly entered the first echelon of active intelligent medical service robot companies. However, from the sub-categories Judging from the above, the overall number of assistive and rehabilitation medical robot companies is the largest.

CCID Consulting data shows that from the perspective of market share structure, rehabilitation robots account for the highest proportion, reaching 47%, while surgical robots account for only 17%.

CCID Consulting pointed out that the application of surgical robots in my country is relatively mature, but the current level of industrialization is relatively low. There are three main factors: First, the application cost is high. The average cost of a single surgical robot is about US$1 million. Taking cardiac mitral valve surgery as an example, the cost of robotic surgery is about US$4,000 higher than that of conventional surgery.

The second is the lack of professional medical staff. In 2017, the country's first international training center for da Vinci surgical robots was established at Shanghai Changhai Hospital. Although it has filled the gap in domestic surgical robot training institutions, its professional talent training supply capacity still needs to be enhanced.

Third, due to the high application cost, the effectiveness of robotic surgery has not yet been fully utilized. Take the da Vinci surgical robot as an example. As of June 2019, the cumulative installation volume of da Vinci surgical robots in my country was 87, and about 40,000 surgeries were completed throughout the year. The average number of surgeries completed by a single machine was 459.8. According to Zhengzhou University No. 1 Data from affiliated hospitals show that in 2018, only one of its hospitals completed 350,000 surgeries. This shows that the efficiency of medical robots still needs to be improved.

Since surgical robots have extremely high precision requirements, involving chip technology, motion algorithms, machinery, electrical, etc., the research and development difficulty and cost are also higher than other types of medical robots. my country's self-developed surgical robots must break through the shackles of technology.

Nowadays, industry experts are slowly deepening their awareness and recognition of robots, and gradually accept this "cold" but powerful helper. Whether you can have your own good helper requires continuous technological breakthroughs by companies in the industry, combined with the characteristics of my country's medical industry, to develop "down-to-earth" good products.
