Human bones, very hard.

The bones of the limbs, the long bones, are among the hardest in them.

Ordinary people have to use a high-powered bone saw for amputation, but Cao Yicong's right hand that needs to be amputated is still such a heterogeneous limb, and the hardness is likely to be higher.

In such a situation, perhaps even a bone saw will be blocked.

And worst of all, there are no bone saws, no other chainsaws, or hand saws.

So when they heard Gu Jun say that they were going to amputate their limbs, except for Cao Yicong, who was becoming more and more dim, Li Liangbin and Wang Yong were stunned, and their hearts were completely bottomless......

"Doctor Gu, what are you going to do?" Li Liangbin couldn't help but ask.

Wang Yong anxiously glanced around, also looking for any sharp weapons that could be used as bone saws.

In fact, it is good to have a kitchen knife now, after all, the most primitive amputation is basically to cut it off directly, and then use cloth to cut it off tightly.

But they didn't bring any cold weapons, the pistol couldn't amputate the limb, and the small scalpel in Gu Jun's hand couldn't amputate the limb......

"I'm going to use this scalpel to do it, including the steps of sawing bones." Gu Jun said seriously, this is the only chance at the moment.

Li Liangbin and the others were stunned, but Gu Jun knew that he was neither joking nor trying blindly, and it was also this Carlop scalpel that penetrated the bones of the leg of the black goat cub that couldn't even be sawed with a chainsaw. It's not a bone saw in a Kalop apparatus, but he has room to maneuver.

"This scalpel is unusually sharp." He explained slightly, "Anything that is harder than iron and stone can be broken." ”

Dr. Gu ...... If you think you can, you can try ......" Cao Yicong gritted his teeth and said, his mind was uncertain, and he was able to endure the huge pain until now he was worthy of the Dongzhou Investigation Department, "If it really doesn't work...... Just give me a ...... Joyfully...... Don't hesitate, don't blame yourself......"

"Vice!" Li Liangbin couldn't help but say anxiously, and Wang Yong also turned red.

They know, they understand, they all have written suicide notes, and they will say the same if they change their position.

Not only did they not want to suffer from it, but because of this harsh swamp environment, supplies were extremely limited, but they did not know where the end would be and when they would be able to recuperate and resupply, and the team could not tolerate such a wounded who could only drag down the whole team.

But, how can it.

"I don't promise you." Gu Jun interrupted their thoughts, and as he spoke, he put the portable medical box on the ground, took out a morphine from the box, and loaded it with an intravenous needle, "Deputy Cao, I'll give you pain relief first, you just hold on, this is just an amputation, don't think about how difficult it is." ”

There was not much time left, and every movement he made was as fast as he could, and he had already choreographed it in his mind before making it.

grabbed Cao Yicong's left hand, rolled up his sleeves, exposed the thick blood vessels on the inside of his left elbow, pulled out the cannula of the needle, pinched the elbow of the injured person with one hand, and pierced the blood vessel at a suitable angle with the needle in one hand.

Gu Jun has not done intravenous injection operations for a long time, but the skills he has practiced from the mice have not been lost, and he has hit the nail on the head and completed it with one stitch.

Only then did I breathe a sigh of relief in my heart.

He knows that the more confident and quick he is, the higher the patient's confidence in fighting the disease and the more tenacious his will becomes.

If he didn't get a needle just now, I'm afraid Cao Yicong's chances of survival would be greatly reduced.

But now, as he expected, Li Liangbin and Wang Yong's confidence has soared, and their eyes are different; Cao Yicong gritted his teeth harder again, also because morphine was working quickly, his consciousness was clearer, and he was willing to try to support it with all his might: "I try to hold ...... as much as possible"

These investigators were the most adept at emotional manipulation, but they also lost their way in the face of illness and pain.

Gu Jun looked around and decided to perform the operation on the spot, there was no particularly good position in the surrounding swamp, and the light here was good, and there was a small piece of hard mud to accommodate. As for the shadowless lamp, operating table, sterile bandage, etc., naturally there are none.

If it is in the surgical building of the medical department, CT and MRI examinations will be done before the operation, and even if it is not good, an X-ray will be done to see the condition of the bones, but there is no one now.

Looking at the things in the small medical box, Gu Jun quietly took a deep breath, an ordinary tourniquet, a few rolls of sterile gauze, two bottles of normal saline, and needles and threads for suturing......

Carlopp's dissecting scissors, dissecting forceps, dissecting hammer, dissecting needle, and several common instruments.

The drugs include procaine for local anesthesia and hemagglutinase for hemostasis......

There are not many things, but there are opportunities, and they must be done at one time, and there can be no waste.

While thinking about the surgical plan, Gu Jun had already picked up the tourniquet and tied it up to the abnormal end of Cao Yicong's right upper limb - the position of the osteotomy plane would be about 5cm below the upper end of the humerus, almost to the shoulder blade, and the entire hand would be amputated from the appearance.

Gu Jun's confidence comes from the right upper arm amputation that he participated in not long ago, and he still remembers the surgical steps, intraoperative precautions, postoperative treatment and complications, and he can do what he needs to do now.

"Hemagglutinase, used to prevent bleeding." While administering medicine and giving Cao Yicong intravenous injection, he deliberately explained to continue to enhance their confidence: "The operation will definitely see blood, don't worry, it's normal, I will ligate all the large blood vessels and other blood vessels, there is no major problem if there is no major bleeding." ”

Wang Yong and Li Liangbin nodded when they heard this, even if they knew that this was a word to comfort them, they still listened to it comfortably.

Gu Jun's wonderful hand is well-known within the Tianji Bureau, and it is not the first time that the field has completed the operation, and there is hope.

"Vice, you just hold on." Li Liangbin was responsible for pressing Cao Yicong's constantly struggling right hand with both hands, and Gu Jun asked Wang Yongxian to go up and press it together before starting to make the flap, because once the blade scratches the skin of the heterogeneous limb, the force of the struggle is likely to increase several times, or even ten times.

One of the most difficult aspects of this operation is that the affected limb is not at the mercy of others, and there is a lack of immobilization tools.

Just because the situation is urgent, you can't give up those delicate operations.

Even if there was a kitchen knife by his side, Gu Jun would not choose to cut off the affected limb directly, if the blood vessels were not gradually dealt with, the injured person would have too much blood during the operation, and he would not be able to stop the bleeding after the operation, and he would not be able to get a blood transfusion, so it would be impossible for him to survive in this otherworldly wilderness.

Therefore, the incision and flap must be done well, and the higher the quality, the higher the survival rate.

Gu Jun gave Cao Yicong's right shoulder a local anesthetic, then picked up the Carlopp scalpel again and started the operation in this harsh environment.
