Medical device
Any related instrument, device, instrument, machine, or substance used to diagnose, treat, or prevent medical conditions, diseases, or disabilities. Medical devices can range from simple instruments, such as thermometers and bandages, to more complex systems, such as pacemakers, MRI machines, or robotic surgical instruments .
History of medical devices
The use of medical devices dates back to ancient civilizations, where early humans developed primitive tools to aid with healing and surgery. In ancient Egypt, archaeological evidence revealed a variety of medical instruments used as early as 7000 BC. These included brass surgical instruments, prosthetic devices and splints to stabilize broken bones.
The ancient Greeks and Romans developed medical technology. Hippocrates, often referred to as the "father of medicine," described more than 200 surgical instruments in his writings. Among the most prominent are gynecological examination endoscopes and various types of forceps. The Romans, based on Greek knowledge, developed more sophisticated surgical instruments, including the famous "Roman scalpel" that remained largely unchanged in design until the twentieth century.
In ancient China, acupuncture needles were developed around 100 BC, representing one of the earliest forms of minimally invasive medical devices. These fine needles were initially made of stone and bone, and later evolved into bronze, gold and silver. The practice of acupuncture, along with associated devices, spread throughout Asia and eventually to the Western world.

Medicine and Instruments in the Babylonian Civilization:
In the Babylonian civilization, which flourished in Mesopotamia (present-day Iraq) from about 1894 BC until its fall in 539 BC, medicine played an important role and was intertwined with religious and magical concepts. Although the Babylonians are not known for the development of medical devices as we know them today, they have important contributions to medicine and treatment using simple tools and primitive techniques.
1. Mud tablets and medical texts:
Babylonians used clay tablets to record prescriptions and treatment instructions. These texts, written in cuneiform script, included recipes for the treatment of diseases and injuries.
The recipes contained natural ingredients such as herbs and oils, sometimes animal portions.
2. Simple surgical instruments:
Although there is little physical evidence, there are indications that tools such as scalpels and needles are used in minor surgeries.
Stone or metal was used to make tools that could be used to extract shrapnel or clean wounds.
3. Medical techniques and magic:
Medical treatment was often accompanied by magical rituals and prayers for the goddess Jola (goddess of medicine) or other gods.
Doctors, known as Aso (physician) and Achebu (sorcerer), combined medical and spiritual treatment.
4. Water use:
Holy water was used as part of the treatment to clean wounds or bathe the sick, believing that it cleanses the soul and body.
Babylonian Legacy:
Babylonian medical contributions were not as complex as those of later civilizations such as the Greeks and Romans, but formed the basis for an older understanding of human attempts to deal with disease. This civilization had an impact on medicine in neighboring societies, as civilizations such as the Assyrians and Persians were influenced by it.
Although there are no "medical devices" in the modern sense, Babylonian practices laid the foundations for folk medicine and healing techniques that developed over time.
The Assyrian civilization, which flourished in northern Mesopotamia (present-day Iraq) between about 2500 BC and 612 BC, was an extension and development of the Sumerian and Babylonian civilizations. In the medical field, the Assyrians relied heavily on a combination of medicine, religious beliefs, and magic, but advanced in documenting medical knowledge and using simple instruments, which can be considered the first beginning of medical devices.
Medical practices and tools in the Assyrian civilization:
1. Medical texts:
Assyrian medical documents, written in cuneiform on clay tablets, contain prescriptions and therapeutic techniques that show a high degree of knowledge of diseases and methods of their treatment.
Surgeries and herbal remedies are documented in Assyrian texts, with reference to the use of hand tools to perform some operations.
2. Simple medical instruments:
The Assyrians used tools made of stone or metal for medicinal purposes, such as:
Lancets: to clean wounds or perform minor operations.
Needles: for suturing wounds.
Vessels: for the preparation and mixing of medicines.
The tools were not sophisticated, but reflected organized attempts to deal with diseases and injuries.
3. Surgical techniques:
Assyrian physicians were skilled in performing simple procedures such as cleaning wounds and treating fractures.
Heat techniques, such as cauterization, were used to sterilize wounds or stop bleeding.
4. Religious and magical practices:
Like the Babylonians, the Assyrians associated diseases with evil spirits and divine punishment.
Medical treatments and magical rituals were combined using spells and symbolic tools to exorcism.
5. Use herbs and oils:
Medicinal herbs and oils were widely used, requiring tools to prepare such recipes as cracking and mixing.
Assyrian contributions:
It is believed that Assyrian physicians (known as "Aso" and "Ashibu") have great knowledge of anatomy, thanks to the tradition of sacrificing animals that enabled them to understand the body. Texts discovered from the library of King Ashurbanipal in Nineveh contain extensive documentation of medical practices and medicines, which were a source of knowledge for later civilizations. Although the Assyrian civilization did not develop complex medical devices, its use of simple tools such as scalpels and needles, along with relatively advanced technologies, shows the beginning of interest in medicine as a separate science. These fundamentals influenced later civilizations such as the Greeks and Romans.

Medieval and Renaissance developments
The Middle Ages saw a slower pace of innovation in medical devices, in part due to the decline of the Roman Empire and the loss of much classical knowledge. However, Muslim scholars preserved and built on ancient medical texts, leading to advances in surgical instruments and techniques. The famous physician al-Zahrawi, known as the "father of surgery," described more than 200 surgical instruments in an eleventh-century medical encyclopedia "styling."
During the Renaissance, there was a resurgence of interest in anatomy and medical science, which led to new innovations in medical devices. Ambroise Barry, a French barber surgeon in the XVI century, made great contributions to the field of prostheses. He designed prostheses and is credited with creating the first mechanical hand. This period also saw the development of more specialized surgical instruments, such as the curved scissors introduced by the German surgeon Hieronymus Fabricius.
The invention of the microscope in the late sixteenth century by Dutch eyeglass makers Hans and Zachariah Janssen marked a pivotal moment in medical history. Although not initially used for medicinal purposes, the microscope would later revolutionize the understanding of the disease and led to many medical breakthroughs.

The Industrial Revolution and nineteenth-century innovations
The Industrial Revolution brought about significant advances in manufacturing technologies, which in turn led to the production of more sophisticated medical devices. The XIX century saw a boom in medical innovation, since many devices were still invented in modern medicine during this period.
One of the most famous medical devices, the stethoscope, was invented by the French doctor René in 1816. Initially, the stethoscope evolved over time to become the binaural device we know today. This invention revolutionized the diagnosis of chest and heart diseases, allowing doctors to listen to internal body sounds with unprecedented clarity.
Other notable innovations of the nineteenth century included:
Subcutaneous needle
Invented by Alexander Wood in 1853, it allowed the accurate delivery of medicines and the development of modern vaccination technologies.
Electrocardiogram (ECG)
It was developed by Willem Einthoven in 1903, which made it possible to record the electrical activity of the heart.
X-ray Machine
Discovered by Wilhelm Conrad Roentgen in 1895, X-rays revolutionized diagnostic imaging and surgical planning.
Sphygmomanometer
Invented by Samuel Siegfried Carl Ritter von Bach in 1881, it allowed accurate blood pressure measurement.
These inventions laid the foundation for modern medical practice and paved the way for rapid progress in the twentieth century.
Regulatory developments and standardization
As medical devices became more complex and widely used, the need for regulation and standardization became apparent. The tragedy of thalidomide in the fifties and sixties of the last century, in which the drug caused severe birth defects, highlighted the importance of rigorous testing and regulation of medical products, including devices.
In the United States, the Food and Drug Administration (FDA) began regulating medical devices in 1976 with the passage of medical device amendments to the Federal Food, Drug, and Cosmetics Act. This legislation established a risk-based classification system for medical devices and defined pre-marketing approval requirements and post-market monitoring.
Similarly, in Europe, the Medical Devices Directive was introduced in 1993, and was later replaced by the more comprehensive regulation of medical devices in 2017. These regulations aim to ensure the safety and effectiveness of medical devices while facilitating innovation and market access.
International standards organizations, such as the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), have played crucial roles in the development of global standards for medical devices. These standards cover various aspects, including:
Quality Management Systems
Risk Management
Biocompatibility Test
Electrical Safety
Program validation
Usability Engineering
The establishment of these regulatory frameworks and standards has significantly improved the safety and reliability of medical devices, enhanced public trust and enabled the global expansion of the medical device industry.
