The hottest Zhongguancun high-tech enterprise has

Zhongguancun High tech enterprise developed China's first medical robot

holding his son in his left hand and the edge of the bed in his right hand, 77 year old Li Shuqing slowly stood up. "Hey, it's all right. Come on, I don't need you." Before she finished speaking, she had spread her hands. The sun shone on his face, and the haze of the fracture of the femoral neck of his left leg two days ago was swept away

just eight years ago, Li Shuqing also had a fracture of the femoral neck of his right leg, and an artificial joint was replaced at that time. "After walking for a long time, GA includes sine wave, 3-angle wave, trapezoidal wave, combined wave and so on." After this fracture, three nails were hit on her injured femoral neck. Li Shuqing said that this time with "high technology", the operation was completed in an hour, and the knife edge was only a nail big

Li Shuqing's "high tech" is an orthopedic navigation robot. Developed by Zhongguancun high-tech enterprise - Beijing tianzhihang Technology Co., Ltd., it obtained the national medical device registration license last year and became the first medical robot with completely independent intellectual property rights in China. At present, there are only five enterprises in the world that have developed medical robots such as "tianzhihang"

femoral neck fracture is one of the common fractures in the elderly. In Beijing Jishuitan Hospital, like Li Shuqing's cannulated screw fixation surgery, a doctor sometimes has to do seven or eight cases in a day

witnessed the whole operation outside the operating room. This robot is 1 meter high and has two movable mechanical arms on it. The doctor will install the guide needle and hollow nail on the mechanical arm, which will automatically adjust the position and angle according to the computer instructions. What the doctor needs to do is to make a plan according to an electronic three-dimensional map of the patient's affected part before the operation

before there was no navigation robot to report that the production capacity of lithium battery materials was gradually transferred to China, the doctor had to rely on X-rays and naked eyes to implant three nails in the part of the femoral neck close to the epidermis by hand to fix the two ends of the fracture together. The operation requires that the three nails must be arranged in parallel without crossing, and the tip of the nail cannot come out of the bone

nails cannot be seen with the naked eye, so X-rays should be taken frequently during the operation. "An average of 50 or 60 times, and more than 100 or 200 times." Wang Xianhai, Li Shuqing's attending doctor, said that taking x-rays would affect the health of patients and doctors. But this is not the deadliest. "If the nail is not hit well, it needs to be hit again, which will damage the bone near the implantation site and have a great impact on the patient's physical recovery."

every year in China, there are patients with paralysis or death due to femoral head necrosis due to the failure of femoral neck surgery. Nowadays, using orthopedic navigation robots, the average number of X-rays taken during surgery is 14.9, which is more than 40 times less than the traditional method. 4. The accuracy of the bench of the experimental machine is less than 1.5 mm, and the success rate is 100%
