Hemostats are essential tools used by surgeons and paramedics to prevent and control bleeding during surgical procedures. The concept of using an instrument to close off a bleeding artery dates back to the first century BC, but the modern hemostat was not in common use until the 15th century. The tool has a pair of jaws that compress tissue, a hinged joint, and a ratchet to precisely open and close the jaws. Hemostats come in different sizes and shapes to meet the needs of different individuals and surgical requirements.
A hemostat, also known as an arterial clamp or hemostat, is one of the most common tools surgeons use during an operation. Hemostats are used to prevent and control bleeding from veins and arteries. These tools are so vital that they are used in almost all types of surgical procedures and are also used by paramedics.
Many surgical techniques and tools were developed hundreds of years before the advent of modern medicine. The use of surgical hemostat dates back to the first century BC, to a Roman physician named Aelius Galen. Although Galen himself did not use hemostats as they are used today, he pioneered the concept of using an instrument to close off a bleeding artery or vessel, so it could be more easily ligated.
Despite this early discovery, the tool was not in common use until the 15th century BC. At that time, Ambroise Pare, a French surgeon and barber, developed a tool he called the Bec de Corbin, or crow’s beak. This was a much cruder version of the instrument that is used today, but it was an important step in the development of modern hemostats.
Similar in structure to a pair of scissors, the modern hemostat has a pair of jaws that are used to compress tissue, rather than cut it like scissors do. The flat surface of the jaws is grooved to improve tool grip and to provide a more efficient surface for compressing tissue.
The hemostat has a hinged joint and a pair of sturdy handles, similar to those of scissors. The other main way medical hemostats differ from scissors is the addition of a ratchet. The ratchet is a toothed bar that attaches to the inside of each handle and allows the surgeon to precisely open and close the jaws of the instrument. Additionally, the ratchet allows the surgeon to hold the jaws in place without having to maintain pressure on the instrument.
Hemostats come in a range of sizes and in slightly different shapes, to meet the needs of individuals with different hand shapes and sizes. Furthermore, various types of hemostats may preferably be used depending on the requirements of the operation. For example, some hemostats have straight jaws, while others have curved jaws, and range in size from five inches (12.5 cm) to ten inches (25 cm) in length.
