Section 118

Is this okay? !

What if you find that you have no feeling in your legs after surgery? !

This is too casual!

Li Cheng definitely couldn't understand it.

Because Zhang Yi's method has been practiced many times in the simulated operating room.

The system will not only evaluate whether Zhang Yi's operation method is standardized.

The success of the surgery will also be assessed.

Currently, Zhang Yi has received full marks for the surgery of replantation of severed limbs.

So he is very confident.

"let's start."

Li Cheng looked at Tang Xiaocheng next to him again.

Tang Xiaocheng gave him a reassuring look:

Trust him!

He is such a boss!

Finally, Cheng Li sighed and started to work as Zhang Yi's assistant.

When setting bones, start with the larger bones first.

Kirschner wires, intramedullary needles, and cross wires are used to connect the thicker tibia first.

There are two bones in the lower leg.

One thick and one thin.

The tibia is thick and plays a load-bearing role.

The fibula is thin and located behind the tibia. It serves as an auxiliary support and participates in the formation of the ankle joint.

"Change drill bit No. 3."

"OK."

Buzz!

Buzz!

After a while, there was a subtle sound of an electric drill in the operating room.

Drill a hole in the tibial tuberosity to prepare for the placement of an external fixator later.

The girl's tibia and fibula were shattered into ten bone fragments of various sizes.

After removing the bone residue that had been washed away, Zhang Yi tried his best to piece the bones together.

Buzz!

Buzz!

Looking at Zhang Yi's skillful operation.

People around were shocked!

How old is this handsome guy?

He looks so young...

Why is the operation so awesome? !

There are also regular training and attending doctors who studied with Li Cheng in the operating room.

Seeing Zhang Yi's skills, they all felt ashamed.

A young doctor couldn't help but be curious, walked up to Tang Xiaocheng and asked:

"Teacher Tang, is this doctor from a big hospital?"

Tang Xiaocheng shook his head:

"He is from the People's Hospital next door."

Shocking jpg!

I knock!

The People's Hospital actually has such highly sophisticated talents? !

They must have spent a lot of money to invite them!

Hey, the second hospital is reluctant to spend money!

So it has always been a little worse than People's Hospital.

On the operating table, the step of fixing the tibia and fibula continues.

After the large skeleton is fixed, intramedullary pins are used to fix the smaller bones.

The bones on both sides of the cross-section have been smoothed to facilitate docking.

After the docking is completed, use steel wire to strengthen the fixation.

before suturing tendons and blood vessels.

Then, place the screws for the external fixator on the left and right sides above the section and five centimeters above the ankle.

The placement of external fixators and internal fixation plates are both options for orthopedic surgery.

The internal fixation plate will need to be surgically removed later.

External fixators are not used.

However, the choice of surgical method depends on the patient's own circumstances.

The girl suffered a comminuted fracture.

In order to splice the broken bones, more than a dozen Kirschner wires and intramedullary needles have been used inside.

Adding steel plates can easily affect the existing fixation effect.

(To add steel plates, you have to drill screws in)

Therefore, using an external fixator to fix the entire calf is currently the best choice for girls.

After the tibia and fibula are fixed, suturing of the tendons begins.

There are many types of tendon suture methods, such as figure-of-eight suture, loop suture, stainless steel wire suture, kessler suture, bunnell suture, etc.

But Zhang Yi’s stitching...

But it was an eye-opener for Li Cheng!

What kind of suturing method is he doing? !

It looks like loop stitching and Kessler? !

I have never seen it before...

Zhang Yi saw the confusion on Li Cheng's face and explained:

"This is my own modified kessler suture, which combines a cross stitch and a 3-loop suture.

The requirement for tendon suturing is that it must be tight and leave no gaps, otherwise it will affect the healing time or the tendon tension will be too strong and cause the tendon to break again.

So I came up with the suturing method that combines Kessler and cross loops.

The movements must be gentle so as not to damage the remaining tendon tissue.

After suturing, cover it with surrounding soft tissue to prevent adhesions. "

Zhang Yi kept explaining the movements of his hands.

As soon as he finished speaking, his suturing was just finished.

Li Cheng looked at it and didn't know what to say.

Several young doctors nearby could only yell at Zhang Yi: Boss 666~

While secretly sighing, when will I be able to be as awesome as this great god...

Next are the blood vessels.

A seven-centimeter-long blood vessel was taken from the dorsal vein of the foot to graft the small saphenous vein.

For popliteal artery vasodilation, it is easy to choose the radial artery on the arm instead.

There is a brachial artery at the upper end of the arm that branches to the elbow.

Branches into an ulnar artery and a radial artery.

Connect the little finger and thumb respectively.

In the case of two blood vessels,

Amputating a section of the radial artery won't have much impact.

The blood circulation in the arm will compensate on its own and find its own path.
