On the afternoon of May 23, the First Hospital of Jilin University was conducting a special surgery. The patient was diagnosed as the humerous H-type fracture, the spinal pelvic separation, the low acetabular precursor fracture. A surgical robot has become the "new assistant" of doctors.
How is the robot to complete the task in this operation?
Sun Dahui, director of the First Hospital of Jilin University, introduced that before surgery, the image was simultaneously transmitted to the robot system by fusion of three-dimensional image scanning. The doctor is designed in the computer navigation system screen, just with a pair of "perspective eyes", it can fix the screw after accurate judgment of the channel security.
"In the past, when manually operated, the surgery screw hit halfway, if the screw position was found, it was completely adjusted through manual operation."
Sun Dahui said, there is a "unknor", you can automate the most reasonable three-dimensional channel through the computer, as long as the doctor's command, "unmanned" will accurately according to the generated path. Located to the surgical position, let the sleeve points to the nail point of the target nail channel. And drill into the guide needle along the sleeve, insert the inside of the patient, and confirm the position is correct, then fix the screw into the guide pin, pull out the guide needle.
This process is somewhat complicated, but under the operation of "unkrennial", it will not be deviated from deviation due to deviation, resulting in blood vessels, nerve damage, which is also invisible to reduce complications.
Through "unknors", the traditional surgery can be used to standardize, so that the surgical error is only 0.1-0.2 mm, which reduces the risk of complex surgery. "Auxiliary surgery with orthopedic robot, the patient's soft residual damage is small, small surgical incision, less hemorrhagic, high safety, faster recovery, and the operation time can be shortened." Sun Dahui said.
The orthopedic surgery robot system consists of a robotic host, an optical tracking system, a main control trolley. Class from the perspective of bionics, the optical tracking system is like the "eyes" of the robot, not only perspective on the depth of the bones, but also monitors each surgical link in real time; the mechanical arm is the "hand" of the robot, the design of the 6-axis, the design is flexible Sexuality and stability, and the main control computer system is equal to the brain of the robot, conveys the doctor's ideas to two equipment to help doctors conduct "path planning".
In the operation, the doctor can perform three-dimensional image scan for the affected area through such a "perspective eye", and accurately position the surgical tool to the surgical position, but do not need to be repeated perspective to determine the nail position, greatly reduce the number of radiation during surgery, let The doctor and the patient are reduced to the lowest. At the same time, it also reduces the risk of patient infection.
According to Sun Dahui, the mechanic has an advantage in the trauma of the spine and limbs, especially in the upper cervical vertebra, scoliosis, spinal renovation, and the surgery of the ankle joint, femoral neck, and acetabular. Patients with routine surgery such as pelvic and acetabs, as well as patients who have made multiple nails, which are inconvenient due to osteoporosis, and is also very beneficial.
Subsequently, the reporter learned from the introduction of the first hospital of Jilin University, the hospital has become a national orthopedic surgery robot application center to be approved by the two commissions, and become one of 21 leading hospitals in the country, and is the only leading hospital in Jilin Province.
