Chapter 2957 【2957】The Hardest Part
The child's grandma said frankly: "That's really unclear. Did he eat food given to him by strangers when he went out to play somewhere?"
The child can't answer it by himself, it can only be guessed by the elders.
In any case, it is important to treat the child.
Regarding the surgery to remove the worms, on the one hand, the family members don’t even have to think about it, hoping to get the worms out as soon as possible; on the other hand, when they think about using a knife on the child’s head, they will eventually have some concerns, and ask how the operation is done , Will it affect the child's brain.
In this regard, first of all, neurosurgery, like other surgeries, has long adopted a minimally invasive approach as much as possible on the road of medical development.
To extract worms, there is no need to cut a big knife on the human head, that is, it is impossible to remove a large part of the human skull for brain surgery.
Xie Wanying briefly explained the general procedure of minimally invasive surgery in neurosurgery to the family: "To make a hole, you only need to make a hole about the size of a one-dollar coin. We will give him a surgical positioning beforehand, determine the location of the hole, and use the surgery With a navigation system, after determining where the worm is, go directly in with the instrument to pinch the worm out."
The human brain is inside the skull, except for the ventricles, it is like densely packed tofu cubes.
Under such circumstances, it doesn't seem very meaningful to remove large pieces of the skull to expose the surface of the tofu block. Because the enlarged incision in thoracoabdominal surgery is to expand the surgical field, it is convenient for the doctor to see inside, and sometimes it is convenient for the doctor's hand to go in and turn the organs directly. The tightness of the brain tissue is destined to prevent doctors from going in for surgery with bare hands, and can only use instruments.
Therefore, in the scene of neurosurgery, it is usually seen that the doctor's hand holding the instrument is like carefully rummaging through the tofu block to find foreign objects for clipping or cutting.
It can be seen from the above that it does not make any difference whether neurosurgery removes large bones or not. Minimally invasive surgery has become the first choice for neurosurgery because of its superiority.
Where is the most difficult part of minimally invasive surgery? We know from previous minimally invasive surgery in other departments that the most difficult part of minimally invasive surgery is blindness. For this reason, minimally invasive thoracic and abdominal surgery adopts the method of laparoscopy, which uses medical instruments equipped with cameras to travel in the human body and become the eyes of doctors to perform this operation.
The premise of laparoscopy is feasible, and the principle is based on the operation of collapsed lung in cardiothoracic surgery, which fully shows that such surgery requires space in the human body for instrument operation.
The brain tissue is crowded into a ball like tofu and fills the space. It is impossible to create a large space for the thoracoscope and laparoscope to walk around in it. In addition to the special structure of the ventricle, there is space for doctors to use, and the endoscopic ventriculoscope we mentioned last time can be used for surgery.
How to solve the blindness problem in neurosurgery minimally invasive surgery depends on Mr. Xie's powerful 3D computing brain, which is actually similar to the 3D navigation system in neurosurgery in subtle ways.
The patient's preoperative brain imaging examinations, including CT scans, magnetic resonance, etc., are taken out and input into the computer to form a three-dimensional image of the patient's brain through software. The doctor compares the patient's head with this three-dimensional imaging to determine the approximate location of the patient's lesion, calculates the shortest and best surgical path from the surface of the brain, and then draws the surgical incision on the surface of the patient's head.
