Chapter 2957 The hardest part

Previous page        Return to Catalog        Next page

    The child¡¯s grandmother said frankly: ¡°I really can¡¯t tell if he ate food given by strangers when he went out to play somewhere.¡±

    The children can¡¯t answer it themselves, so the elders can only guess.

    No matter what, it is important to treat the child.

    Regarding the surgery to remove the worms, on the one hand, the family members don¡¯t even think about it and hope to get the worms out as soon as possible. On the other hand, when they think about having to operate on the child¡¯s head, they will eventually have some concerns and ask how the surgery is done.  , will it affect the child's brain?

    At this point, first of all, neurosurgery, like other surgeries, has long been as minimally invasive as possible in the development of medicine.

    To remove worms, there is no need to make a big incision on a person's head, that is, it is impossible to remove a large piece of the person's skull for brain surgery.

    &#24378&#29306&#32&#32&#35835&#29306&#12290 Xie Wanying briefly explained the general process of minimally invasive neurosurgery to the family members: "To make a hole, you only need to make a hole about the size of a one-yuan coin. We will know it in advance.  We will perform surgical positioning on him, determine the location of the opening, use the surgical navigation system to determine where the worm is, and then directly insert the instrument inside to pinch out the worm."

    This time 75 zw .com Zhang Si.  The human brain is inside the skull. Except for the ventricles, it is like a densely packed tofu block.

    Under such circumstances, it does not make much sense to remove large chunks of the skull to expose the surface of the tofu block.  Because the expansion of the incision in chest and abdominal surgery expands the surgical field, it is easier for the doctor to see inside and sometimes it is easier for the doctor's hands to directly go in and turn over the organs.  Due to the tightness of brain tissue, doctors are destined to be unable to operate with their bare hands. They can only use instruments.

    So in the scene of neurosurgery, what is usually seen is that the doctor's hand-held instruments are like carefully digging through tofu blocks to find foreign objects for clamping or cutting.

    From the above, it can be seen that for some operations, it makes no difference whether neurosurgery removes large bones or not. Minimally invasive surgery has become highly superior and has become the first choice for neurosurgery.

    What is the most difficult part of minimally invasive surgery?  We know from previous minimally invasive surgeries in other departments that the most difficult aspect of minimally invasive surgeries is blindness.  For this reason, minimally invasive surgery on the chest and abdomen is done through laparoscopy, which uses medical instruments equipped with cameras to travel around the human body and become the eyes of the doctor to perform the surgery.

    The premise for the feasibility of laparoscopy is based on the principle of lung collapse in cardiothoracic surgery, which fully demonstrates that such surgery requires space in the human body for instrument operation.

    The brain tissue is like tofu cubes packed into a ball and filling up the space. It is impossible to create a large space for a thoracoscopic laparoscope to move inside.  In addition to the special structure of the brain ventricles, which has space for doctors to use, the endoscopic ventriculoscope we mentioned last time can be used for surgery.

    How to solve the problem of blindness in minimally invasive neurosurgery depends on Xie¡¯s powerful three-dimensional computing brain, which is actually subtly similar to the three-dimensional navigation system of neurosurgery.

    Control the big one and control the owl.  Take out the patient's various preoperative cranial imaging examinations, including CT scans, magnetic resonance, etc., and input them into the computer to form a three-dimensional image of the patient's brain through software.  The doctor uses this three-dimensional imaging 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 a surgical incision on the patient's head surface
