Chapter 2957 [2957] The most difficult place

The child's grandmother said frankly: "It's really hard to tell, did he eat food from strangers when he went out to play somewhere."

The child can't answer by himself, the elders can only guess.

Anyway, it is important to treat the child.

On the one hand, the family members do not have to think about the operation to remove the worms, hoping to get the worms out as soon as possible. , will not affect the child's brain.

In this regard, first of all, neurosurgery, like other surgery, has taken a minimally invasive approach as far as possible on the road of medical development.

There is no need to cut a large knife on the human head to take a worm, that is to say, it is unlikely that a large piece of the human skull will be removed for brain surgery.

Xie Wanying briefly explained the general procedure of minimally invasive surgery in neurosurgery to her family: "To make a hole, you only need to make a hole about the size of a one-yuan coin. We will give him a surgical positioning beforehand, determine the location of the opening, and use the surgery. The navigation system is used to determine where the worm is, and then directly enter the device and clip the worm out."

The human brain is inside the skull. Except for the ventricles, it is like densely packed tofu.

In such a situation, removing the large pieces of the skull to expose the surface of the tofu block does not make much sense. Because the expansion of the incision in the chest and abdomen is to expand the surgical field, it is convenient for the doctor to see the inside and sometimes it is convenient for the doctor to directly go in and turn the organs. The tightness of the brain tissue is destined for doctors to be unable to go in and perform surgery with bare hands, and can only use instruments.

Therefore, in the scene of neurosurgery, it is usually seen that the doctor's instrument is like carefully digging through the tofu block to find the foreign body for clipping or cutting.

As can be seen from the above, neurosurgery does not make any difference for some operations to remove large bones or not. Minimally invasive surgery has become the first choice for neurosurgery with high superiority.

Where is the most difficult part of minimally invasive surgery? We can know from the previous minimally invasive surgery in other departments that the most difficult part of minimally invasive surgery is blindness. To this end, the minimally invasive method of the chest and abdomen is performed by means of laparoscopy, and a medical instrument equipped with a camera is used to travel around the human body and become the eyes of a doctor to perform the operation.

The premise and principle of the feasibility of laparoscopy is based on the operation of lung collapse in cardiothoracic surgery, which fully shows that such an operation requires room for the instrument to operate in the human body.

The brain tissue is crowded into a ball like tofu, and it is impossible to create a large space for the thoracoscope and laparoscope to wander in it. In addition to the special structure of the ventricle, there is room for doctors to use it, and the endoscopic ventriculoscope we mentioned last time can be used for surgery.

How to solve the blindsight problem in neurosurgery minimally invasive surgery, this is about Xie’s powerful 3D computing brain, which is actually similar to the neurosurgery 3D navigation system.

Take out the patient's preoperative head imaging examinations, including CT-film MRI, etc., and input it into the computer to form a three-dimensional image of the patient's brain through software. The doctor determines the approximate location of the patient's lesion by comparing the patient's head with this three-dimensional stereoscopic imaging, calculates the shortest and best surgical path from the brain surface, and then draws a surgical incision on the patient's head surface.
