The child's grandmother admitted: "It's really hard to say whether he ate food given by strangers when he was playing outside."
The children couldn’t answer the question themselves, so the elders had to guess.
No matter what, it is important to treat the child.
Regarding surgery to remove the worms, on the one hand, family members don't even have to think about it and hope to get the worms out as soon as possible. On the other hand, they will have some concerns when they think about operating on their child's head, and ask how the surgery will be performed and whether it will affect the child's brain.
In this regard, first of all, neurosurgery, like other surgical procedures, has long been taking minimally invasive approaches as much as possible on the road of medical development.
To remove the worms, there is no need to perform major surgery on the human brain. In other words, it is not possible to remove a large piece of the human skull to perform brain surgery.
Xie Wanying briefly explained to the family the general process of minimally invasive neurosurgery: "We only need to make a hole about the size of a one-yuan coin. We will do surgical positioning beforehand to determine the location of the hole, and use the surgical navigation system to determine where the worm is, then directly insert the instrument to clip the worm out."
The human brain is inside the skull, and except for the ventricles, it is filled with densely packed tofu blocks.
In this case, removing large chunks of the skull to expose the surface of the skull is not very meaningful. Because the enlargement of the incision during chest and abdominal surgery is to expand the surgical field, which makes it easier for doctors to see inside and sometimes makes it easier for doctors to directly go in and turn over the organs. The tightness of the brain tissue means that doctors cannot perform surgery with their bare hands and can only use instruments.

Therefore, in neurosurgery scenes, what is often seen is the doctor holding instruments in his hands, like carefully searching for foreign objects in a block of tofu to clamp or cut them.
From the above, it can be seen that whether or not neurosurgery removes large pieces of bone makes no difference to some operations. Minimally invasive surgery has become the first choice for neurosurgery with high superiority.
What is the most difficult part of minimally invasive surgery? We know from previous minimally invasive surgeries in other departments that the most difficult part of minimally invasive surgery is blindness. Therefore, minimally invasive chest and abdominal surgery adopts the laparoscope method, using medical instruments equipped with cameras to move inside the human body and become the doctor's eyes to perform the surgery.
The premise for the feasibility of laparoscopy is that the principle is borrowed from the operation of collapsing the lung in cardiothoracic surgery, which fully demonstrates that such an operation requires space in the human body for the instrument to operate.
The brain tissue is like a tofu block, which is packed with space. It is impossible to create a large space for the thoracoscope and laparoscope to move around. Except for the special structure of the ventricle, which has space for doctors to use, the endoscopic ventriculoscope we talked about last time can be used for surgery.
How to solve the blindness problem in minimally invasive neurosurgery? This has to do with Xie’s powerful three-dimensional computing brain, which is actually subtly similar to the three-dimensional navigation system of neurosurgery.
The patient's preoperative cranial imaging examinations, including CT scans and magnetic resonance imaging, are input into the computer and a three-dimensional image of the patient's brain is formed through software. The doctor uses this three-dimensional image to compare the patient's head to determine the approximate location of the patient's lesion, calculate the shortest and best surgical path from the brain surface, and then draw the surgical incision on the patient's head surface.
