The board of directors of Shanghai MicroPort MedBot (Group) Co., Ltd. (the ?Company?, together with its subsidiaries, the ?Group?) (the ?Board?) announced that the SkyWalker orthopedic joint arthroplasty surgical navigation and positioning system (the ?SkyWalker Hip and Knee Joint Arthroplast Surgical Robot?), which is independently developed by the Group, has obtained approval for launch from the National Medical Products Administration of China (the ?NMPA?), becoming the first domestic orthopedic surgical robot for hip and knee equipped with self- developed robotic arm obtaining approval from NMPA. The SkyWalker Hip and Knee Joint Arthroplast Surgical Robot assists total knee arthroplasty (TKA) and total hip arthroplasty (THA) surgeries, featuring platform, standardization, precision and personalization. Its preoperative planning system creates 3D models of knee joint and hip joint based on patients' preoperative CT scan data and formulates personalized prosthesis implantation plans according to patients' physiological and anatomical features; during surgery, it utilizes the self- developed highly dexterous and lightweight robotic arm(s), allowing osteotomy and grinding to be completed precisely with human-machine collaboration.

The robot delivers better rectification results on postoperative lower limb alignment as compared with traditional surgeries, evidencing the improvement in accuracy and efficiency of surgeries brought by the robot. Being the only domestic hip and knee compatible orthopedic surgical robot with self-developed robotic arm at present, the SkyWalker Hip and Knee Joint Arthroplast Surgical Robot can provide precise positioning during the surgery for precise knee joint osteotomies and acetabular grinding to precisely recover lower limb alignment of patients. It also realizes more precise and efficient osteotomy and grinding and prosthesis implantation as compared with traditional hip and joint arthroplasty.

Its intelligent assistance system can avoid damages caused by positioning medullary cavity in traditional surgery and reduce risks of dislocation associated with mispositioned acetabular cup implantation or even surgical failure, so as to reduce surgical complications and help patients achieve faster recovery after surgery. As the devices involved in acetabular grinding, acetabular cup implantation and knee joint osteotomies are basically the same as traditional surgeries, the robot can significantly shorten learning curve of doctors, allowing them to adapt to the system quickly with proficiency.
