Robot “Dr. Huhjoon” Succeeded Clinical Operation

The Korea Advanced Institute of Science and Technology (KIST) Medical Robotics Research Group said on October 24, “It is possible to use ‘epidural neuroplasty’ to treat existing back disk pain without needling or needing surgery, Dr. Huhjoon ‘was developed, “he said.

The researchers succeeded in the first trial of the preclinical test using the carcass (car dumbbell) with the robot “Dr. Hur Jun” at the Severance Hospital of Shinchon Yonsei University. Last year, the research team, together with Professor Shin Dong-ae of Yonsei University, confirmed the function of Dr. Huh Jun in several pre-clinical animal experiments using pigs.

A catheter is a tube made of rubber or metal that is used to draw liquid from the body or inject drugs. Epidural neuroplasty is a procedure that alleviates inflammation and alleviates symptoms by injecting drugs into the nerves damaged by inflammatory reactions such as back disks and stenosis.

The procedure begins with a Magnetic Resonance Imaging (MRI) device that locates the lesion and inserts a special catheter into the spinal canal through a hole in the tail bone of the spine. Then remove the inflammatory substances and other attachments from the central nervous system and nerve branch to treat the area where the nerve is pressed. Finally, to prevent recurrence, inject drugs or cut off the laser-protruding disc.

In the existing procedure, there is a risk that both the doctor and the patient are at risk of radiation exposure and the image quality of the image is lower because of the small size of the catheter.

The team developed the ‘Dr. Hurjun’ to remotely locate and control the position of the catheter tip, which can escape the risk of radiation exposure. The catheter has a small diameter and a high-resolution ultra-small camera is installed, enabling precise procedures. Dr. Huhjun is equipped with a 3-mm-diameter catheter containing laser procedures and an illumination channel.

The Dr. Hur Jun robot system can be remotely driven by a haptic master device that can move the robot catheter mounted on the robot arm freely in six directions. The doctor can calculate the three-dimensional position of the catheter (VR) navigation system which is provided to the user.
