The accuracy of the fracture reduction robot can reach millimeter level

Recently, there is good news from Beijing Jishuitan Hospital that the hospital has signed a conversion agreement with Beijing Rosenbolt Technology Co., Ltd. on the "Intelligent Fracture Reduction Robot Technology Achievements", with a total amount of 100 million yuan. After more than a decade of research, this intelligent fracture reduction robot has achieved a technological leap in orthopedic surgical robots from assisting in positioning and navigation to completing surgical operations. It is the first to achieve clinical application in the most difficult pelvic fracture surgery worldwide, filling the international gap. Compared with traditional surgery, intelligent fracture reduction robots break through the limitations of traditional surgery in terms of brain, eyes, and hands through automatic preoperative surgery planning, real-time 3D navigation visualization during surgery, and precise operation of force position collaborative robots. They achieve precision, minimally invasive, and low radiation, becoming the "super assistant" of doctors. This robot is also a microcosm of the combination of technological innovation and medical care in this city, benefiting the people. Traditional surgery relies on manpower and experience, which is different from ordinary straight bones such as the femur and tibia. The pelvic structure is unique, as the name suggests, and the pelvic shape is circular, like a pelvis. Once a fracture is broken, the difficulty of repair can be imagined. Wu Xinbao, Vice President of Beijing Jishuitan Hospital, said that traditional pelvic repair often relies on surgical procedures, requiring doctors to open the fracture site, expose the fracture location in the pelvic area covered with blood vessels and nerves, and reduce the fracture with bare hands, and finally fix it with steel plates. This method is highly traumatic and requires anesthesia, blood transfusion, and a long recovery time. With the advancement of medicine, orthopedic surgeries nowadays pursue minimally invasive, minimally invasive, and fast recovery. Before the invention of intelligent fracture reduction robots, when it comes to the "manual version" of minimally invasive pelvic reduction surgery, Wu Xinbao sighs: This surgical method requires the cooperation of multiple people, at least 4 doctors, because pelvic repair requires aligning the fracture line, which requires a certain amount of tension. One person is responsible for pulling the upper limb and the other person is responsible for pulling the lower limb. The tension generated by the tension allows the soft tissues, ligaments, and muscles around the pelvis to bind and automatically reposition the fracture. At the same time, the surgeon also needs to repeatedly adjust the fracture position under X-ray fluoroscopy. Once the reduction is determined to be satisfactory, Then everyone holds it still and an experienced doctor injects a temporary fixing needle to frame the pelvic structure. The process of repositioning always makes the doctor sweat profusely. After fixing the needle, with the help of radiation, screw the fractured bone seam for repair and fixation. To perform the surgery well, it largely depends on the experience of the chief surgeon. The entire operation often takes three or four hours, which makes the doctor exhausted The robot can automatically plan the restoration path in the intelligent orthopaedic laboratory of Beijing Jishuitan Hospital. The reporter of Beijing Youth Daily saw the world's first intelligent fracture restoration robot. This robot is closely integrated with the operating table, and installed at the bedside is a monitoring system, equivalent to the robot's "brain". Through the NDI tracking camera, it can display real-time image data of the patient's body during surgery, plan reset paths, display surgical data, and so on. On one side of the bed is a holding system that can fix the patient's pelvis through a holding needle at the end, and on the other side of the bed is a movable robotic arm that can be adjusted by force and angle,
