A brief history of medical technology: from ancient Egyptian prostheses to human genetic projects

From the broadest perspective, the history of medicine and health technology is very long. Related parties have recently confirmed that the world's oldest "prosthetic limb" is an ancient Egyptian toe prosthesis made of wood and leather, and it appeared in 950 BC! Although the rapid development of medical technology in recent decades has been unmatched by ancient times, history cannot be ignored, and some important creations have contributed to the development of today's medical industry.

In 1816, Reineck invented the stethoscope

French doctor Renéke is a true gentleman: when auscultating a lady for heart disease, he was suddenly inspired to roll up the newspaper and put it on the patient's chest. This is the prototype of a stethoscope. Dr. Reineck's invention not only improved the efficiency of medical treatment, but the story behind the invention was also spread as a beautiful talk.

In 1895, Roentgen discovered X-rays

It is said that when German scientist William Roentgen tested the cathode tube, he observed that a nearby fluorescent screen was illuminated, and the rays illuminating the screen seemed to be able to pass through various substances and would not be completely reflected like visible light. At that time, Roentgen did not understand the significance of this ray in the medical field, until he took a photo of his wife's hand with this ray (called the "Roentgen" ray for a long time). This photo and the ring in the photo have become classics in medical photography for centuries, and X-rays have long become standard equipment in hospitals.

In the 1940s, transistors made possible small implants

The research on transistors can be said to be a credit to "Bell Labs". Because the development of transistors has matured, many formerly large medical devices have been able to reduce their size. The emergence of implantable cardiac pacemakers, life-saving devices, and other transistors has become commonplace. Of course, thanks to the "Moore's Law" of vigilance, your iPhone will be so smooth.
