Doctor Song handed over the ventriculoscope sheath. The teacher did not tell her to stop. Xie Wanying took over and felt the feel. Every doctor has a first time doing manual work, so there is no need to be overly nervous.

After arriving at the neurosurgery department, you will find that neurosurgery has a lot of high-end surgical tools, which seems to be much more than other departments, as if to further demonstrate the unshakable Mount Everest status of neurosurgery from another perspective.

At first glance, the ventriculoscope seems to be "more advanced" than the laparoscopic choledochoscope, as evidenced by the fact that it seems to be more expensive.

What makes it so expensive?

For example, when using laparoscopic choledochoscopes in the National Association, Xie Wanying had never seen protective films put on these tools during surgery. Now the nurses put a thick transparent plastic bag on the handle of the ventriculoscope sheath in her hands, which was obviously to prevent various splashing pollutants from contaminating the high-end instruments during surgery.

The tools used are expensive, which puts pressure on doctors.

The tools in the hospital are not for doctors to use carelessly. If they are damaged by improper use, the doctor will be held responsible.

In clinical practice, you can often see some old directors who, every time they let the young people try new things, can't help nagging: Be careful when using it.

I'm just afraid I can't afford the compensation.

As I mentioned before, when something is purchased, the hospital will deduct the cost of the item from the department's profit every month. This is equivalent to the department borrowing money from the hospital to buy the item first and then repaying it in installments after use, and all department staff share the burden.

How expensive is this thing? Perhaps not as expensive as a choledochoscopic scope. The choledochoscopic scope she used for external hepatobiliary examination was a soft scope. The structure of the soft scope made it impossible for the nurse to put a plastic bag over it to isolate and prevent contamination.

Soft lenses are usually more expensive than hard lenses.

In any case, be very careful to hold the handle with only two hands.

High-end medical equipment is most afraid of being dropped or bumped into.

Hold it firmly with both hands to prevent it from falling, keep a calm mind and have enough strength.

Secondly, you need to know the tools you are using.

Before the operation, the nurse prepared everything and let her touch and understand it closely, so that she could understand the ventriculoscope that she was touching for the first time. The structure of the sheath is relatively simple, because its function is to establish a hard channel like the outer sheath of the puncture needle, and the real ventriculoscope can be inserted after the guide core inside is pulled out.

As for the sheath, as mentioned before, what is more important is the action that the doctor performs to insert it into the skull.

She knew how heavy this thing was because she had touched it before the operation. As for the actual feel of the operation, she couldn't have the natural feel of Brother Cao. It was her first time to operate it, so she naturally had no practical experience and could only rely on her brain to control her hands.

Xie Wanying is confident in her brain. To transfer her brain to her hands, she relies on a stable mentality and the ability to draw inferences from one instance to another with her hands.

With people around her looking at her, she started to do her first practical exercise without anyone stopping her.

Huang Zhilei and Sun Yubo felt a pang of fear in their hearts and were filled with trepidation.

Several classmates, including Wei, said in their hearts: Xie is a warrior as always.

Shi Xu is fine. After being scared several times by classmate Xie in General Foreign Language Class 2, he will not be easily fooled or frightened again.

The other two bosses and Song Xuelin did not speak, but just observed silently.

For big guys and geniuses, the focus of observation is definitely not whether a person is brave or not, but what kind of IQ confidence allows this person to be so brave.

If you are like Lu Zhishen, it won’t work. If you are like Einstein, you need to be patient and think about it.

Student Xie once revealed that his secret is to grasp the angle.
