Tang Yuanqing frowned, his thoughts instantly returned to the battle-torn battlefield of the Vietnam War, and said sadly: "Back then, a shell fell eight or nine meters in front of me and exploded!" The few young fighters standing in front of me were ...... I was sacrificed, and I was also slightly injured, and here it is. Pen, fun, pavilion www. biquge。 info" raised his palm and patted his waist.

Sighing, Tang Yuanqing said again: "Back then, the hygienist only took out the shrapnel outside, then gave me medicine and bandaged it. Pieces of metal, no, should be shell fragments...... I guess that's when I stayed inside. ”

Li Feichen, Tang Jianzhong, Tang Shiyin and Guo Zhengsheng all suddenly realized and showed admiration.

"This device, called the intestinal microdoctor, can take out the fragments of the shell, but I haven't tried it yet, so I don't know if it's reliable." Li Feichen said with a serious face.

Guo Zhengsheng immediately expressed his doubts: "How to take it?" "His face was full of seriousness.

Li Feichen lightly tapped the screen with his finger, and a small round hole door automatically opened on the right side of the top of the intestinal microdoctor.

HE USED HIS INDEX FINGER AND MIDDLE FINGERNAIL TO CAREFULLY TWIST A METAL WIRE ABOUT 0.1 CM IN DIAMETER AND ABOUT 3 CM IN LENGTH FROM THE SMALL ROUND HOLE DOOR, AND EXPLAINED: "THIS IS CALLED THE INTESTINAL KNIFE LINE, WHICH IS A MINIATURE MACHINE, WITH THE FRONT END IS THE TRACTION HEAD, THE MIDDLE SECTION IS THE WIRELESS COMMAND RECEIVER AND WIRELESS CHARGING RECEIVER, AND THE TAIL IS A SCALPEL. Its size is too small, and the power it carries is very limited, and it can only rely on wireless charging to work uninterrupted. Although it is called a penetrating knife line, it can also work in blood vessels, and theoretically, can reach any point inside the human body. ”

"That's amazing!" Tang Yuanqing was surprised.

Seeing Tang Jianzhong, who is well-informed and knowledgeable, he couldn't help but exclaim: "So advanced?!" ”

Li Feichen smiled slightly, pulled out a few intestinal piercing knife lines from the small round hole door, and patiently explained: "The work efficiency of a intestinal piercing knife line is very slow, and at least two or more are needed for each operation, and they work together to deal with a surgical target." This intestinal penetrating microphysician can command up to 36 intestinal penetrating knife lines at the same time to deal with the same surgical target. ”

It is not possible to command two batches of intestinal penetrating knife lines at the same time, and it is not possible to deal with two different surgical objectives.

Even if its CPU processing power is okay, there is nothing it can do about wirelessly charging two batches of sausage knife wires at the same time, because it can only send weak current waves in one direction.

If you want two batches of intestinal penetrating knife wires to receive wireless charging current, you can only increase the distance between the intestinal penetrating microdoctor and the intestinal penetrating knife wire, and then increase the voltage and transmission power.

However, the voltage is too large and the magnetic field is too strong, which not only affects the collaborative work between the intestinal knife wires, but also seriously endangers the safety of the human body.

After a pause, Li Feichen said again: "As for taking the metal pieces from Old Man Tang's kidneys, there are two sets of plans. First, pierce a pinhole in the waist, put the intestinal knife line through the needle hole, and directly pull out the metal piece, or pull it into the rectum, this plan hurts a little more, but the speed is faster. Second, through the nostrils, the intestinal knife line is put into the kidney, and then from the kidney to the outside of the kidney, and the metal piece is pulled into the kidney, and then into the rectum, which is very slow and less harmful. ”

"Put the thread of the intestine piercing knife in the water and let my grandfather drink the water into his stomach, can't he?" Tang Shiyin asked softly.

Li Feichen's gaze moved to Tang Shiyin's cheek, gestured lightly, and explained: "Yes, but it's not fast. Because, to take this piece of metal, it takes at least five threads to penetrate the intestines, and five threads and water to drink into the stomach will disperse into the throat, stomach, or intestines, and I can only control the threads of the intestines one by one into the kidneys, and the speed is really not fast. From the nostrils, you can get five lines of sausage knives lined up to get in. ”

Everyone nodded in understanding.

"You haven't tried it?" Tang Jianzhong looked suspicious.

"Hmm." Li Feichen nodded solemnly and said, "I want to find a pet dog, try it first." ”

Tang Yuanqing waved his hand and said with courage: "No need, just use your first plan, stick a needle in my waist, and pull the metal piece into my rectum." ”

Recovering his blazing gaze, he swept over the faces of Tang Jianzhong, Tang Shiyin and Guo Zhengsheng one by one, and Tang Yuanqing said again: "If you are not at ease, you can call an ambulance." ”

Guo Zhengsheng looked at Tang Jianzhong inquiringly, and when he saw that the other party nodded slightly, he immediately took out his mobile phone, walked outside the bedroom, and called an ambulance to come to the Tang family's compound, ready at any time, just in case.

"Come on." Tang Yuanqing lay down with his back face, lifted his clothes, and let the left side of his waist be exposed to the air.

Li Feichen asked, "Are there any injection needles and disinfectant water?" ”

"Yes." Tang Shiyin immediately took out her mobile phone and called Liu Shuang.

Less than three minutes.

Liu Shuang walked into the bedroom with a medicine box, put the medicine box on the bedside table, and neatly opened the lid of the box, took out a bottle of iodine-containing disinfectant and an injection needle, and put it on the medicine tray.

Li Feichen sat on the chair, picked up the injection needle, washed the needle with disinfectant first, and suddenly saw the narcotic drugs in the medicine box, and suddenly felt ashamed: "I almost forgot." ”

He then asked, "Old Man Tang, do you want to get an anesthetic injection first?" ”

"If you don't fight, will it hurt?" Tang Yuanqing also wanted to be heroic.

Tang Jianzhong persuaded loudly: "Dad, it's an operation, how can it not hurt?" Let's take a local anesthetic needle. Feichen, if you are not familiar with it, let Liu Shuang fight. ”

"Okay." Li Feichen then gave up his position to Liu Shuang.

Liu Shuang obviously learned to inject injections, she skillfully took out an anesthetic, inserted the needle, put it into the anesthetic, and gently pulled the needle handle, and the syringe was full of anesthetic liquid.

She picked up a cotton swab soaked in disinfectant water, wiped Tang Yuanqing's waist first, and then pricked the needle into the flesh, gently pushing the anesthetic liquid into his body.

After the injection, she stepped aside.

Li Feichen sat back on the chair, took out five intestinal knife lines, cleaned them with disinfectant water first, and then stuffed the front end of a intestinal knife line into the pinhole in Tang Yuanqing's waist.

Afterwards.

He picked up the intestinal piercing microdoctor, and remotely controlled the intestinal piercing knife line to drill into its body, leaving only a little tail.

Then pick up the second intestinal penetrating knife line, let it pull the head of the machine to suck the scalpel at the first tail, and then take the intestinal penetrating microdoctor, remote control......

The head and tail ends of the thread are magnetic, and the middle section is non-magnetic.

Soon.

The five threads of the intestine piercing knife line drilled into Tang Yuanqing's body end to end, quickly entered the kidneys, and under Li Feichen's remote control, they dispersed and began to cut the rust chips of the metal pieces and the surrounding fat.

When the metal piece was loosened, Li Feichen controlled the intestinal knife line to penetrate the kidney wall, and then pulled the metal piece into the inside of the kidney, and then pulled it in the direction of the rectum.

The whole process was very smooth, Tang Yuanqing didn't feel the pain, and Tang Jianzhong and Tang Shiyin looked at the screen of the intestinal microdoctor with a relaxed face.

Fifteen minutes later.

Li Feichen took out all five intestinal penetrating knife threads, then took a suture that could be absorbed by the human body, tied it to a intestinal penetrating knife line, and then remotely controlled the intestinal penetrating knife thread into Tang Yuanqing's body, and used sutures to suture the wound of the kidney.

Finally, the sutures were removed, and the entire operation was completed, and the whole process took about 20 minutes, leaving only an almost invisible needle in the waist.

Of course, Tang Yuanqing still had to poop to pull out the metal sheet, and then take anti-inflammatory drugs for a few days to completely recover.
