There are snake-shaped medical robots to help doctors perform minimally invasive anesthesia.

Tencent Digital (Compilation: Hamish) may appear in the future: a serpent-like snake robot that looks like a snake enters the human body through the nose or urethra. Don't worry, it comes to save people's lives.

For more than a decade, Nabil Simaan, a professor of bioengineering at Vanderbilt University, has been working on snake robots. In 2003, Simaan served at Johns Hopkins University when he and colleagues developed an early snake robot prototype that could be used for upper respiratory surgery.

After this, Simaan kept repeating this idea: The snake robot can enter the hard-to-reach areas of the doctor through a small incision, reducing the impact of the surgery on the patient.

"We finally designed the best form of snake robots. They can bypass the anatomical barriers, which means that doctors will be able to reach the hidden parts of the body. This is the most advanced robotic surgical technique," said Simaan.

"Recently we have been studying a serpentine robot that can enter the body through the patient's nose and then descend into the upper respiratory tract for microsurgery. What's special about these robots is that they can sense the path of advancement and can participate in the doctor's During the surgery, they do not need to be placed in a specific place in advance, they will automatically reach the affected area,” said Simaan.

This research has made it much easier to use difficult procedures in the past. For example, this snake-like robot can enter the body from the patient's nose, bypass the vomiting reflex zone, and perform vocal cord surgery without anesthesia.

In addition, it can also enter the urethra and help treat bladder cancer. "We will study this in the next few months," he said. "Ultimately we will let the snake-like robot enter the human body from the urethra to achieve bladder cancer treatment."
