[Chinese instrument network instrument research and development] Usually, when the ultrasound examination shows that there is a shadow in the liver, it will be suspected of having a tumor, followed by a biopsy to confirm. The doctor will use a long probe to take samples from the suspected tissue and test it in the laboratory, but it is not an easy task to accurately position and guide the needle. The medical and biotechnology automation project team at the Fraunhofer Institute for Production Technology and Automation and the Institute for Medical Image Computation used robots to solve this problem ingeniously and is expected to be completed automatically by robot arms in the future.
On the one hand, the doctor must make sure that the sample taken is a tumor, not just a few micrometers of healthy tissue. On the other hand, the needle cannot injure other organs such as veins, nerves, and lungs. In addition, when encountering skeletal structures such as ribs, the probe could not be worn.
With the robot arm, the doctor can use it to accurately insert the needle, and the entire positioning process from the original 30 minutes to a maximum of 5 minutes. The technology will be displayed on MEDICA at the International Medical Devices and Devices Exhibition (Dederdorf) on November 17, 2016.
In order to see the location of the tumor, a computed tomography scan (CT) is required to determine the insertion site and path of the needle. With the aid of a set of software developed with CT images and MEVIS, after analysis, calibration and simulation, the robotic arm can determine the path of the sampling needle and guide the doctor to complete the sampling step by step. The accuracy of the robot and the experience of the experts complement each other.
This technique is also applicable to the tumor treatment process using similar means, for example, by the probe conducting heat, cold or high-energy radiation into the diseased tissue to destroy the tumor.
In addition, in order to ensure that the needle path is consistent with the design, doctors also need to use X-ray imaging to monitor the sampling process. Because the whole process is guided by the robot arm, not only the doctor's hand is prevented from obstructing the imaging, but also the radiation damage to the doctor's hand is reduced. At the same time, the amount of radiation that is accurately sampled for the patient is also reduced.
