The system takes me for surgery

Chapter 291: Intelligent Robotic Arm

Li Junhao brought Liang Yi to his studio.

When Liang Yi saw those mechanical arms after he entered, he raised his hand to greet them.

Li Junhao said: "How about it, is my mechanical arm very enthusiastic?"

"It's a bit enthusiastic. Your studio is brightly lit. If there is no light, if there are so many big arms waving to me suddenly, then I won't be scared to death." Liang Yi smiled wryly.

"Haha...that picture is really..." Li Junhao laughed.

"What's the matter?" Liang Yi asked.

"No hurry, no hurry, I'll show you right now. This thing is a product of my accident, and it was a product of inadvertent insertion." Li Junhao said happily.

"This is normal in the history of product development. The purpose of the sex aid in the small blue pill was to treat angina pectoris, coronary heart disease and other diseases that have plagued human beings for a long time, rather than to activate sexual function. Unexpectedly Now it’s a magic medicine for strengthening yang.”

"That makes sense." Li Junhao patted his head and smiled. He walked in front of a warehouse, pressed a button, and the door of the warehouse opened.

Liang Yi saw a robotic arm and robotic legs, and asked, "Your Gundam robot is finished?"

"No...that's too difficult, take your time, this is a bionic prosthesis." Li Junhao said.

Liang Yi knows that there are many bionic prosthetics in the medical device market, but this kind of sensory feedback effect can be given to amputees through neural implantation of electrodes, but this method will bring certain risks, because it requires A large amount of autologous nervous tissue and some damage to it.

For nerve implanted electrodes, firstly, the electrode may not be able to be arranged at the desired position inside the nerve, and secondly, it is not easy to fix the electrode body after implantation, and the position of the electrode is easily moved by external force, so it is not conducive to long-term implantation.

So he has been not very optimistic about this kind of bionic prosthesis, and asked: "Are you connected by nerves?"

Li Junhao said quite confidently: "Of course not, that kind of connection method is not practical."

"Then how did you do it?"

"I use the brain to sense cortical microcurrent stimulation."

"What's the principle? It's so tall!"

"It is to implant electrodes in the cerebral cortex to form a brain-computer interface, so that high amputees can control the prosthesis through brain electricity and provide prosthetic feedback. An implanted electrode array can record the signals of 100-200 neurons. The recorded neural signals will be After being transmitted to the decoded neurons, the discharge pattern can be identified, and it is compiled into corresponding movement instructions according to the law of the discharge pattern, thereby driving the prosthesis to complete the movement."

"Is it stable?" In Liang Yi's opinion, the most important thing for this kind of life-like compensatory tool is stability. This work cannot be carried on, and may be in danger of life.

"If it's not stable, why would I ask you to come and take a look." Li Junhao took a hat that was similar to a normal hat, but with a slightly thicker top, and said, "Brother Yi, put the hat on and put your hands in your pockets. Control this robotic arm with your mind."

Liang Yi listened to Li Junhao's guidance, and slowly tried out the mechanical arm he made. In the early stage of the trial, he was not very flexible, but as he continued to make movements with his mind, the information transmitted to the mechanical arm became more and more powerful. After getting richer, the arms became more and more flexible.

At first, you can only do some simple fist grips.Slowly, I was able to lift some small things, and when I tried slowly, I was able to grasp very fine chopsticks, and then picked them up to pick up things. This is a very important sign of quality of life for a Chinese.

Liang Yi gave Li Junhao a thumbs-up with the mechanical arm and said, "This arm is great, it is the gospel for those patients with missing limbs."

"The silicone bionic model you mentioned before is now ready, and this robotic arm is studying that simulation model. By imitating the working principle of nerves, such a branch product was made."

"Didn't you say that nerve roots and spinal cords cannot be imitated?"

"I spent a lot of money to find a polymer material and found that there is a substance that is very similar to the conduction mechanism of nerves and spinal cord. With this substance, my bionic man is complete."

Hearing what he said, Liang Yi was already very excited, and said, "Let me see."

"Since this bionic man was made, I haven't let anyone see it. You are the first one."

"Got it, I'll keep it a secret." Liang Yi nodded.

After Li Junhao opened another warehouse, they saw a bionic man lying on the operating table.

This simulated man is very realistic to the real person, Liang Yi tried to touch the soles of his feet with his fingers, and it felt like real people's feet.

Liang Yi thought of Meibao and Andy, and suddenly said with an open mind: "Then you said that if it is equipped with a fully intelligent system, wouldn't the robot be completely humanoid?"

"If there is a team that can achieve complete mechanical control, coupled with my set of bionic materials, it can indeed be realized." Li Junhao said.

"I think there will be some teams that can make mechanical control capabilities come to you to cooperate soon." Liang Yi said with a smile.

"Brother Yi, pick up the KA scalpel you are most familiar with!" Li Junhao handed the scalpel to Liang Yi using the standard surgical nurse's method.

"Give me the scalpel, why?" Liang Yi asked.

"How can you inspect the product if you don't dissect it? How will you know that my bionic manipulator is doing a good job?"

"Such a beautiful Simulator, are you willing to let me give it to Huo Huo?"

"I'm a bit reluctant, but if it's just a good-looking thing on the outside and a bunch of straw bags inside, then how can I sell it?"

"Then I'd rather be obedient than respectful." Liang Yi took the scalpel.

According to the surgical method, drape the simulator, and then dissect layer by layer, and carefully explore the skin blood vessels and nerves.

Before Li Junhao showed Liang Yi the semi-finished product, it was enough to amaze him.Now that the finished product is placed in front of his eyes, Liang Yi always feels for a moment that this is an operation on a real person.

This simulated human not only has a body temperature, but also a respiratory system, and the circulatory system can hear the sound of the heart beating and pumping blood.

When Liang Yi intentionally cut the arteriole, blood gushed out like real blood. He quickly clamped it with a hemostat, and then ligated it with No. 7 suture to stop the bleeding.

"What you did is so similar, it's almost like a real person's operation." Liang Yi sighed.
