Recently, the first seven axis cooperative robot assisted total hip arthroplasty in China was successfully completed in the Second Affiliated Hospital of Xi'an Jiaotong University.
The reporter learned that the robot "artrobot" used in this operation was born in Hangzhou future science and Technology City, which is more than 1000 kilometers away from Xi'an. The robot R & D enterprise is Hangzhou Jianjia robot Co., Ltd. (hereinafter referred to as "Jianjia robot").
Jianjia robot was established in Hangzhou future science and Technology City in 2018. It is a medical device company providing accurate joint replacement solutions, with many years of experience in surgical robots and surgical navigation robots. Xu Jing, the founder of the company, has worked in the medical device industry for more than ten years.
He introduced that "artrobot" is a seven axis hip replacement surgery robot independently developed by Jianjia robot“ The human arm has 7 degrees of freedom from the shoulder to the palm. This robot has the flexibility of a human arm. "
It is understood that in 2019, the number of artificial joint replacement operations in China exceeded 700000, and maintained a rapid growth of more than 20% year after year. However, in the traditional hip arthroplasty, there are some problems, such as inaccurate operation, inaccurate clinical effect, excessive dependence on experience and so on. The research and development of surgical robot makes up for these shortcomings.
It is understood that compared with the six axis surgical robot mainly used in the world, "artrobot" has absolute advantages in force control interaction. At the same time, it realizes the whole process coverage of "preoperative accurate reconstruction, intelligent planning, intraoperative accurate control, flexible hand feeling, postoperative comprehensive evaluation and real-time feedback", which significantly improves the accuracy of prosthesis placement.
Professor Wang kunzheng, chairman designate of the branch of orthopaedics of the Chinese Medical Association and director of the joint surgery center of the Second Affiliated Hospital of Xi'an Jiaotong University, said in an interview: "this operation completely adopts the first seven axis cooperative robot independently developed in China. Doctors can not only accurately locate, polish and install the prosthesis on the acetabular side, but also accurately locate and cut on the femoral side, ensuring that the data error related to the actual operation and preoperative scheme is within 1mm, and the installation angle deviation is less than 1 degree. "
"We are not just a simple domestic import substitution, but a deep combination of clinical actual needs and technology upgrading iteration, so as to realize domestic innovation in the real sense." Xu Jing said.
At present, surgical robots are having a revolutionary impact on medical technology. In recent years, international medical device giants have also made great efforts to layout the field of orthopaedic surgical robots. He said that the company is committed to developing China's first joint replacement surgery robot to provide competitive, accurate, efficient, safe and reliable comprehensive solutions for hospitals.
According to Xu Jing, at present, "artrobot" has entered the clinical trial stage. It is expected that the registration will be approved next year, and it is expected to become the first domestic joint replacement robot to obtain the registration certificate of the State Drug Administration.
"In addition to 'artrobot', we are also developing other new products." Xu Jing said that in the future, Jianjia robot will continue to focus on the core needs of doctors and patients, continue to innovate, accumulate and make progress, and jointly promote the medical technology progress in the field of joint replacement and orthopedics in China.
