Medical Tools That Have Stood the Test of Time

Medical tools have come a long way since the early days of medicine, but some tools have stood the test of time and many health-care providers are still using them today. These tools have proven their effectiveness and reliability through generations of medical professionals. Explore several of the medical tools that have stood the test of time and continue to play a critical role in patient care. From the stethoscope to the scalpel, let’s take a closer look at the essential medical tools that continue to save lives every day.

Air Gages

One of the earliest uses of air gages in the medical field was to measure needle sizes in the early 20th century. Today, the industry uses air gages to measure needles of various types, catheters, and other surgical instruments that require high-precision measurements to ensure they meet industry standards. Air gages are an essential tool in manufacturing medical devices, where precision is critical to ensuring patient safety and optimal outcomes. Because they provide high accuracy, reliability, and versatility, medical professionals continue to use air gages in various applications, making them a time-tested and valuable tool for ensuring quality and precision in medical devices.


The stethoscope is perhaps the most iconic medical tool that has stood the test of time. French physician René Laennec invented it in the early 19th century, and it quickly became a staple in medical practices around the world. Today, the stethoscope remains an essential tool for diagnosing heart and lung conditions. It allows doctors and nurses to listen to the sounds of the body’s internal organs and detect any abnormalities. Despite advances in technology, the stethoscope continues to be the go-to tool for diagnosing a range of cardiovascular and respiratory conditions.


Otoscopes are medical devices used to examine the ear canal and eardrum. They have been in use for over 150 years and remain an essential tool in diagnosing ear infections and other ear-related conditions. Otoscopes come in various shapes and sizes but typically consist of a light source and a magnifying glass. By shining the light into the ear canal and using the magnifying glass, modern doctors and nurses can get a clear view of the eardrum and diagnose any problems, just as their colleagues have done for more than 100 years.

Reflex Hammers

Reflex hammers consist of a handle and a rubber head and have been in use for almost 200 years. A medical professional will tap the tendon with the rubber head, causing the muscle to contract. Doctors and nurses use reflex hammers to test for neurological conditions such as Parkinson’s disease and multiple sclerosis. Reflex hammers continue to be an essential tool in diagnosing neurological conditions, despite advances in technology.


Scalpels are surgical instruments used to make incisions in skin and tissue. They have been in use for thousands of years and remain an essential tool in modern surgery. Today, manufacturers make scalpels in various shapes and sizes and use different materials such as stainless or carbon steel. However, medical professionals made the first scalpels using flint and obsidian. Despite new surgical tools and techniques, scalpels continue to be the go-to tool for many types of surgeries due to their precision and reliability. With proper training and skill, scalpel use can lead to successful surgeries and patient outcomes.
