"Two minutes and fifty-seven seconds?"

Everyone took a deep breath, and time seemed to be frozen. Everyone's eyes were frozen on these amazing numbers, and their expressions were full of incredibleness.

Within three minutes, such a complex craniotomy is not sure that even the craniotomy machine can reach this speed!

"How is that possible?"

"Did the timing start halfway?!"

The instrument nurse, anesthesiologist and others could not understand that the doctor's speed actually exceeded the craniotomy machine?

This is the craniotomy of the brain stem hematoma removal surgery...

The base of the skull is full of irregular cartilage bones, while the body of the posterior fossa is actively small. It is connected to the spinal canal through the vertebrae and the lower part is separated from the brain by the small meninges. There are oval small meningeal fissure holes in the front, and there are trigeminal nerves, internal carotid arteries, the second to six pairs of cranial nerves, ocular arteries and middle duramen arteries and other key structures.

In addition, the craniotomy of the posterior fossa is also very likely to cause bleeding, such as the suboccipital muscles, the blood vessels next to the midline of the occipital bone, the posterior mastoid blood vessels, the inferior occipital venous plexus, etc.

However, Xu Qiu completely controlled the rhythm of the entire operation in just three minutes, and took Mo Wan and Tang Yunshu to complete the skull opening at an incredible speed.

"It's simply...unthinkable!" The anesthesiologist was shocked.

He has followed many surgeries in the Department of One-brain surgery, and there are also bleeding in the brainstem area of ​​up to more than ten milliliters, but the craniotomy machine was delayed for five minutes, and all the doctors dared not to exert their entire operation.

But what's going on now...

Craniotomy with brain stem hemorrhage suddenly became simple.

First, open a skull window, then cut the dura mater several times, and then... is finished?!

...

"Come on."

Xu Qiu took a deep breath.

Three minutes...

Although this speed is not slow, it has not reached its limit.

The master-level craniotomy brings Xu Qiu a clinical intuition, surgical feel, and... control over the entire operation that is far beyond ordinary people.

All the tedious operations were simplified to within three minutes. Everything seemed as fast as thunder, but Xu Qiu still made many small designs.

One of the difficulties in the surgery for posterior fossa is bone flap formation.

The curve of the posterior skull fossa is too large and is deeply trapped in the muscles behind the occipital. On the one hand, it is difficult for the operator to perform easy operations in this area. On the other hand, the lower part of the bone flap is closely connected to the venous sinus, making it easy to cause venous sinus damage and bleeding.

Patients entering the skull from here are often more critical. For example, today's patient No. 2 - if there is another venous sinus bleeding, it is almost like driving a rocket on the way to visit the King of Hell.

Therefore, Xu Qiu made many details based on the patient's own situation.

The first is drilling.

Before, Tang Yunshu and Mo Wan only saw his unmoving hands.

For laymen, what they can see can reflect the level of the artist, only the hand shaking or not, and whether the opening point is accurate enough.

In fact, Xu Qiu specially selected the first hole to drill at the junction between the transverse sinus and the lower edge of the sigmoid sinus.

The second hole is three centimeters away from the first airspace, close to the bottom of the upper line, and this position can expose part of the transverse sinus.

The last hole is above the inner condylar vein below the outer bottom.

This drilling point just needs to be used to the stereotactic projection line method mentioned in Xu Qiu's lecture. The most suitable third hole site is the junction of the inner projection of the lower edge of the sigmoid sinus.

Xu Qiu's three-hole method can effectively expose the edge of the sinus.

Simply put, it is human body stroke.

If you can see where the sinus is clear, the risk of damage during the operation will naturally be minimized.

Moreover, the range of the bone window opened by the three holes is the smallest area that can accommodate Xu Qiu for subsequent hematoma removal, and the best surgical field.

All this may sound simple, but in fact it needs to be applied to surgery, even with a craniotomy machine, it is difficult to practice.

Isn’t the No. 1 Ore the junction between the transverse sinus and the lower edge of the sigmoid sinus?

But in fact, the anatomical variability in this place is very large, with herringbone seams, top and cushion seams intersecting, and the various positioning marks also vary greatly. It is not easy to find the positioning point of hole No. 1.

The remaining two hole positions must also be estimated based on hole No. 1 to perform indirect positioning.

For example, in the three-hole method, the posterior edge of the mastoid process needs to be removed between the first hole and the third hole to form a bone groove connecting the two bone holes, and the bone groove only has an extremely thin inner skull plate.

Here, it is necessary to locate the junction between the mastoid tip and the scaly slit and the apical and maxillary slit, then make a straight line extension, find the projection of the ascending segment of the sigmoid sinus, and use the projection to carry out the next step of dura separation, etc.

Therefore, unless the number one hole can be accurately found, Xu Qiu's three-hole method will backfire... Once the number one hole is lost, the other two hole positions will also be greatly miserable!

If Director Zhu and Chief Director were here, they would probably be so shocked that they could not speak.

The most terrifying thing is not that Xu Qiu can complete the precise positioning of these places.

If Director Zhu, Director Da and others came to power, they might be able to do it.

but……

They need time.

The positioning of each place takes a few minutes just to have the approximate range, and then it is finely locked. Finally, it may take more than ten minutes to complete all this before you have the confidence to use the knife.

But Xu Qiu completed all this in three minutes and completed the craniotomy!

However, Mo Wan and Tang Yunshu only saw that Xu Qiu's hands were very stable and fast, and they trained them very comfortably...

They are not experts in brain stem hematoma removal surgery, but they are calm and just silently obey Xu Qiu's orders and silently shout 666 in their hearts.

...

Crazy-

Xu Qiu's movements continued to accelerate.

After opening the dura mater, the next operation will be much easier.

Of course, it is just a simplicity in operating coefficient, it is nothing more than decompression, elimination of hematoma, and inhalation of bleeding. If there is a brain hernia, it will be retracted, and finally stop the hemog and end it.

However, the risk is much higher than the step of craniotomy.

As a former brain restriction area, the brainstem is a field that only a very small number of elite doctors are qualified to enter.

Attract cerebrospinal fluid...

Turn it up gradually...

Entering the little meninges...

Then, the margin of the little meningeal and trochanter nerves, bbe veins, trochanter nerves, etc. are exposed...

Under the microscope, the patient's mesponsorption, superior cerebellar artery and other structures were exposed.

After this, Tang Yunshu and Mo Wan's hands became a little stiff.
Chapter completed!
