It’s amazing: these 12 innovative and bold medical technologies have saved humanity.

Foreign media recently released the "Best Technology Inventions in History" atlas series, taking stock of various inventions that change people's ways of doing things and improving people's lives. The seventh part is about medical innovation, which helps improve the health of humans.

Laser eye surgery

Using lasers to correct vision is now commonplace. It's really cool to restore your vision to near perfection in just a few minutes.

Brain surgery

The surgeon must first remove a portion of the skull cover to be able to access the patient's brain tissue. During surgery, doctors can use electrodes to stimulate specific areas of the patient's brain. Sometimes, patients need to stay awake during the surgery.

Caesarean section

This type of surgery involves setting a knife in the abdomen to deliver the child. This procedure is usually used when the baby or mother is facing medical risks.

Infectious Disease Tests

Infectious diseases are caused by microorganisms, such as bacteria, viruses, fungi, and parasites.

Doctors suspect an infection based on the person's symptoms, physical examination results, and risk factors. First, doctors confirm that the person has an infection rather than another type of illness. For example, a person with a cough and difficulty breathing may have pneumonia (a lung infection). However, the person may instead have asthma or heart failure, which are not caused by infection. In such a person, a chest x-ray can help doctors distinguish pneumonia from the other possible disorders.

Once doctors confirm that the person has an infection, they usually need to know which specific microorganism is causing the infection. Many different microorganisms can cause a given infection. For example, pneumonia can be caused by viruses, bacteria, or, rarely, fungi. The treatment is different for each microorganism.

Many different types of laboratory tests can identify microorganisms. Laboratory tests use a sample of blood, urine, sputum, or other fluid or tissue from the body.
