Wow! Have you noticed what our century is happening right now? It’s really cool, right? We already have a lot of modern technologies around! Want to know some of them? Sure! Why, not?! Here it goes.
Medical technology allows doctors to treat diseases and to perform complicated surgery under safer conditions. Imaging techniques produce a clear, electronic picture of the inside of the body so that doctors can pinpoint problems. Endoscopy enables doctors to look directly to a viewing tube inside the body to see what is wrong.
Together, imaging and endoscopy mean doctors can perform minimally invasive, or ‘keyhole’, surgery, entering the body, through the smallest of incisions (cuts). This minimizes tissue damage and makes recovery time for the patient shorter. The use of lasers, such as the laser scalpel, to cut through tissue, remove growths and seal blood vessels is much more effective than standard surgical methods.
Computers are now a major part of medicine. They are used in scanning to generate and store images and to transmit them elsewhere. Virtual-reality systems are used to train doctors in surgical techniques without having to touch a patient.
Doctors use endoscopes to look inside the body to diagnose or treat diseases. Modern endoscopes are narrow and flexible and are inserted either through body openings into the digestive, respiratory, urinary, or reproductive systems, or through incisions in the skin into body cavities. Endoscopes use long, thin optical fibers to illuminate and transfer the images to a video monitor, which the doctor looks at while he or she conducts the examination. The endoscope may also have, for example, tiny forceps to carry out a biopsy (the taking of a tissue sample) for diagnosis.
Imaging techniques enable doctors to look inside the body to make diagnoses and plan treatment without having to cut open the body. One example of it is the X-rays. This was the only useful imaging method until the 1970s. Since then a new generation of techniques has been developed. Although they work in different ways, all scan a particular body region piece by piece and use a computer to make two- or three-dimensional images.
Ultrasound is the most common of the imaging techniques. It uses inaudible, high-frequency sound waves that are reflected from body parts. It is a safe method for observing unborn babies and viewing moving parts, such as blood flow through the heart.
CT scanning uses X-rays. PET – positron-emission tomography – scans use radioactive substances that, when they are injected to the body, give off radiation and reveal the parts of the human body where cells are active.
Today, many diseased or damaged body parts can be replaced. The earliest replacement parts were prostheses such as wooden legs. Modern prostheses, such as plastic arms with moving fingers, are more lifelike. Internal replacement parts are a relatively recent development.
Transplantation takes a living organ from a donor and inserts it into the patient. Kidney transplants, for example, are made to treat people with kidney failure. The body’s immune system regards transplanted organs as ‘foreign’ and attempts to reject them. The transplant patient has to take drugs that prevent rejection by reducing the effectiveness of the immune system.
Implants are artificial internal devices that are not rejected by the immune system. They include artificial joints that can replace diseased joints and electronic pacemakers that regulate heart rate.
So, how was your reading? Don’t you realize something? Aren’t you amazed? Well.. well… well…
