Great doctor starts with adding points

In fact, in normal surgical operations, some more mature doctors actually don't pay attention to so many details, and just make a single cut, as long as the incision doesn't deviate, it's fine.

Anyway, there won't be a lot of bleeding.

Lu Junyin and He Ling looked at each other and said nothing. This operation is relatively simple, so no matter which faction Wu Xie is more inclined to, it doesn't hurt much, as long as the operation is completed.

And the removal of the internal fixation device——

The thinking of the two quickly became rigid and they forgot to continue to think deeply.

because.

On the operating table at this moment, after Wu Xie cut the incision from Chen Tao's original scar with the lancet, a gap appeared in front of them, but there was no blood flowing down like a column in their impression!

Um?

This is a scar wound, where is the blood?

When normal skin is cut, there is also blood.

What did Wu Xie do just now, isn't it just a knife?

Then focus on the wound made by Wu Xie. Wu Xie has put down the surgical lancet at this moment and plans to change it to an electric knife.

It is well known that the scar tissue formed after surgery will cause more bleeding when the surgery is performed than when the initial surgery was performed.

He Ling and Lu Junyin are both old doctors, and this kind of cognition is already common sense, and it is not surprising.

Because the vascular density of scar tissue is relatively low, the vascular structure is relatively complex, and it is easy to be damaged by surgery. At the same time, the blood vessel elasticity of scar tissue is poor, and it is easy to rupture and bleed.

And because the scar tissue has lost the elasticity and toughness of normal skin tissue, the internal structure of the tissue is tight and hard, the compression and pulling of the tissue during the operation will cause the scar tissue to break, resulting in increased bleeding.

Moreover, after the last operation, in the case of tissue damage, the body will release inflammatory mediators, leading to aggravated inflammation in the tissue, dilation of blood vessels, increased permeability, and local bleeding.

Based on these common-sense cognitions and the previous experience of bleeding more when making surgical scar incisions, the two of them were a little at a loss at the moment. They didn't expect how Wu Xie did it.

Wu Xie switched to electric knife, in fact, to avoid bleeding.

Wu Xie saw that he was holding the electric knife at this time, but the two assistants did not cooperate with him to unscrew the surface of the skin on the opposite side, so he raised his head slightly and narrowed his eyes: "Director, can you help me divide the incision? Otherwise, I'm afraid of hurting you." skin surface."

The function of the electric knife is electrocoagulation or electrocautery, both of which have the function of hemostasis, but if it accidentally scalds the surface of the skin, it will easily lead to skin necrosis and produce unexplainable scars, and the tip of ordinary electric knife is generally not Small.

Lu Junyin hurried to help.

Then stare at Wu Xie's operation, and you can find it.

Wu Xie started the electrocoagulation incision, but when the incision depth continued to sink, under the sizzle of the electric knife, there was still no blood oozing out, let alone the perfusion of blood vessels that were accidentally cut .

The refreshing surgical wound made Lu Junyin and He Ling even more incredible, and at the same time they were more focused.

Wu Xie didn't pay attention to the expressions of the two of them, and continued to push down. Wu Xie only lowered the electric knife to the subcutaneous tissue layer, and then switched to a vascular forceps for blunt separation!

And after opening and separating a small opening, he bluntly made up and down transverse cutting movements with vascular forceps quite skillfully, tearing off the subcutaneous fascia layer, exposing the muscle layer.

At this time, Wu Xie also saw that Lu Junyin and He Ling were quite stiff in their movements, so they took the thyroid retractors in their hands respectively, and added the subcutaneous fascia layer to the pulled away tissue, and then began to identify the muscles , after finding the muscle gap.

Quickly pick it apart again with vascular forceps, and push up and down horizontally to tear open the connection between the muscle gaps, completely exposing the steel plates and screws that are close to the bone ends.

However, on the steel plate and the screw, there are a large amount of scar tissue, which gathers at the nut position of the screw and on both sides of the steel plate.

Seeing this, Wu Xie was not in a hurry, but opened the gap between the muscles further, and completely separated the upper and lower edges of the steel plate with all his strength.

The patient's previous fracture was a mid-tibial fracture, and the plate was placed on the medial side.

So there is enough intermuscular space for Wu Xie to perform...

The proficiency of this operation and the familiarity with muscle anatomy do not seem to be a newcomer who is just getting started, because many newbies don't know how to walk the muscle gap at all, and may choose to cut the muscle directly.

For all surgeries, the bigger the wound, the easier it is to see directly, and the easier it is to operate.

Wu Xiesai picked up the electric knife again and began to cut the lump of scar tissue. The barking sound and the grilling smell of scorched protein sucked away most of it along the suction device, and the remaining part was poured into the nostrils of everyone, stimulating The taste buds are slightly excited.

After Lu Junyin swallowed two mouthfuls of saliva, he turned his attention to Wu Xie's operation again, while still looking at the overall surgical wound.

At this moment, I have to use two words to describe it, clean and refreshing, and pure refreshing is hard to describe.

No gore.

And seeing the wound that Wu Xie cut before, there was bright red coagulated blood, which did not seep or flow, as if inlaid on the surface, with blood scabs to prevent blood from oozing out.

This kind of performance made Lu Junyin faintly doubt the correctness of the operations and wounds he had done before.

For the first time, he also doubted the so-called practical school he firmly believed in.

Are the operations I have done before really practical?

Are Wu Xie's works really academic?

The operation is still going on. There are a total of six screws in the plate, but there are nine holes in the plate, three holes cover the previous fracture line, and the other six holes are the anchor points of the plate.

At this moment, Wu Xie has already cut the lump-like scar tissue in the upper and lower three holes and separated the nut butt of the screw, and is just waiting to use the special screwdriver for internal fixation to screw it out directly.

The nut except for one screw is covered by muscle tissue, which is particularly difficult to operate. The other nuts are exposed to the naked eye, and the operation is simplified again.

"Master Equipment, take the hexagonal screwdriver for internal fixation, thank you." Wu Xie put down the electric knife and made a request in a leisurely manner.

The hexagonal screwdriver was put on.

Before Wu Xie was about to operate, Lu Junyin made a special confession: "Remember to use even force, otherwise the screw will easily slip or slip."

Even though he explained this, Wu Xie's previous operation gave him enough shock and doubts, so he didn't bring up the idea that he planned to give Wu Xie a demonstration operation.

Wu Xie slowly corresponded one by one, and then the sound of the screws "creaking and creaking" continued to come out. After a while, in four or five minutes, Wu Xie took out the six screws one by one into the curved plate.

There was a crisp clanging sound.

After finishing this, Wu Xie handed the curved plate back to the equipment nurse, and said at the same time: "Master of equipment, please check the number of screws with the tour teacher. There are six screws, the number is accurate, and there are no broken nails."

Wu Xie's words made the eyes and faces of the two itinerant nurses in the operating room, including Dong Chun, a little dazed.
