Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to an orthopedic repositioning robot. Background Art

[0002] Using orthopedic robots to perform surgery on patients can provide orthopedic surgeons with detailed preoperative planning and precise intraoperative operations, making the surgery safer and less invasive, and also beneficial to the patient's later recovery. Therefore, the application of orthopedic robots in surgery is becoming more and more common.
