In the operating room of Shijiazhuang Third Hospital, doctors perform operations with the assistance of orthopedic surgical robots.
In the operating room, under the operation of the doctor, the robotic arm of the orthopedic surgical robot with the harmonic reducer as the core rotation drive slowly moves, stops steadily at the patient's pelvic position, and accurately fixes the sacroiliac screws in the optimal position along the preset path through a 5 mm incision that has been cut on the patient's body.
This is like a scene from a science fiction movie, which happened in the operating room of the Third Hospital of Shijiazhuang. The surgery, assisted by an orthopedic surgical robot, successfully reduced and fixed the pelvic fracture for 52-year-old Mr. Liang, with an intraoperative blood loss of only 20 milliliters, and he was able to walk on crutches two days after the operation.
Orthopedic surgical robots assist doctors in carrying out surgeries, bringing orthopedic surgery into an era of precision and intelligence. A few days ago, the reporter walked into the third hospital of the city and visited the application of orthopedic surgical robots.
Putting on a hand gown, a surgical mask and a sterile cap, crossing three thresholds, under the leadership of Tian Lijun, director of the Second Department of Traumatology, the reporter stepped into the operating room. The orthopedic surgical robot standing next to the operating table is particularly eye-catching, and unlike our traditional impression, it is not a humanoid robot, but a set of precision instruments and equipment with a robotic arm.
Tian Lijun told reporters that the orthopedic surgical robot is composed of three parts: optical positioning camera, operation console, and robotic arm, which serve as the eyes, brain, and hands of the robot. Among them, the optical positioning camera is the "clairvoyant eye", which is responsible for collecting data and monitoring the surgical process. The main console is the "smart brain", which is responsible for helping doctors plan the surgical path. The robotic arm is the "stable hand", and the doctor can perform surgery through the robotic arm to achieve sub-millimeter accuracy.
"Robotic surgery is not a robot to complete the operation, but to become a doctor's surgical assistant." Tian Lijun explained that traditional orthopedic surgery is highly dependent on the experience of doctors, and there are three major pain points: "invisible, inaccurate, and difficult to quantify". The orthopedic surgical robot can provide doctors with accurate surgical paths through preoperative three-dimensional image reconstruction, and accurately locate them during the operation, assisting doctors to complete difficult operations, and the search for implant points can also be done in one step, which greatly improves the accuracy and safety of the operation and shortens the operation time. By accurately tracking the position of surgical tools, it can also effectively reduce the amount of X-rays used during surgery, reduce the radiation exposure of patients and doctors, and greatly enhance the safety of surgery. In addition, the amount of intraoperative bleeding was significantly reduced for patients performing surgeries using orthopedic surgical robots, and the pain level of postoperative patients was relatively light, and the recovery speed was faster. Many patients are able to perform simple walking exercises with the assistance of a walker on the second day after surgery, which greatly shortens the length of hospital stay and improves the patient's recovery experience.
Like ordinary doctors, orthopedic surgical robots put on "surgical gowns" and "fight" with doctors in a strictly sterilized environment to become the "best assistant" of doctors. It is reported that as the first hospital in Hebei Province to introduce orthopedic surgical robots, the Third Hospital of Hebei Province has completed a number of advanced orthopedic minimally invasive surgical treatments with the assistance of robots.
