In January 2022, the Smart Tissue Autonomous Robot (STAR) performed laparoscopic a medical procedure on the delicate tissue of a pig with practically no human assistance. Laparoscopic surgery includes little cylinders embedded into the midsection or pelvis to control tissues.

The News-Letter had the valuable chance to examine the automated framework with Axel Krieger, an associate teacher and innovator from the Department of Mechanical Engineering, and Jin Kang, Jacob Suter Jamer educator and master in optical imaging, detecting, fiber optics and photonic frameworks from the Department of Electrical and Computer Engineering.

History of robotic surgeries

Krieger’s advantage in fostering an robotic system that could perform laparoscopic medical procedure started in 2011 while he was working in Children’s National Hospital in Washington, D.C. as an examination teacher. He started the thought with Dr. Michael Hsieh, a urologist at Children’s National Hospital. And afterward teamed up with Kang to make appropriate imaging frameworks.

Robotic surgical system initially showed up around 50 years prior. However, clinical field did not apply them until 1980s. Then in the end of 1980s Robodoc, a picture directed framework, was utilized for prosthetic hip substitution. From that point forward more mechanical headways have been made. So, robotics can perform neurosurgeries, gynecological medical procedures and urological medical procedures.

The first robot to perform laparoscopic surgery

STAR is the main robot to perform laparoscopic medical procedure with practically no human assistance. The principle objective behind this robotic surgery is to perform independent anastomosis, the surgery of two adjoining veins. It requires profoundly mind boggling imaging, tissue observing and careful arranging methods inside the gastrointestinal tissues.

The current rendition of STAR is adjusted from the 2016 model. This model acted in open careful settings with tissues limited by outside apparatuses. Interestingly, the current model permits repetitional, unpredictable stitching, a kind of mechanical framework that permits admittance to the midsection and pelvis without making enormous cuts. The greatest distinction between this robotic system and the other existing robots is that it permits medical procedures without human assistance. In addition, STAR specialists just need to choose the expected careful plans, and the robot will execute the excess undertakings freely.

Krieger further clarified the distinction among Smart Tissue Autonomous Robot and other existing robotic systems.

“The large distinction [between STAR and other robotic surgical systems] is this change in perspective [from teleoperated to independent system],” he said. “Administrators used to have to sit on the control center and direct every movement of the robot, which is right around an augmentation of human hands. Presently with STAR, a robot can perform complex pieces of the medical procedures with simply specialists’ management.”

Main hurdles in making STAR

As per Krieger, one of the fundamental difficulties in making STAR was figuring out how to screen tissue development in the human body over the long run inside a restricted space. To battle this test, Krieger worked together with Kang, whose examination essentially centers around creating optical methods for biomedical applications to make a 3D imaging framework that comprises of close to infrared cameras (NIR) and 3D cameras. The 3D imaging framework permits the robot to reproduce a 3D model of the tissue. Then to follow tissue development and energy when the patient is breathing and during time periods stitching steps.

In a meeting with The News-Letter, Kang examined the primary capacities and premises of the 3D imaging framework. The group expected that, similar to people, the robot would require an insight framework in light of sight. 3D imaging would permit the robots to evaluate visual qualities. For example, distance, which is significant for making exact stitches.

Kang recommended that their present objective is to work on the speed of the 3D imaging framework. And to get all the more continuous estimations of tissue development without forfeiting the precision.

During a meeting with The News-Letter, Krieger remarked that the medical field is pushing toward automated frameworks. And this change would democratize patients’ admittance to surgeries with less disparities between each medical result.

Krieger likewise noticed that robotic systems are not intended to supplant specialists. They are devices that help specialists in performing with more repetition, and steady assignments with high accuracy.

“The specialists [still] do a huge piece of the surgeries. But [we would utilize the robots] for the specialized, troublesome sewing that requires such countless fine developments with consistency and repeatability,” he said.
