Everything about Hemostat totally explained
Invented by
Stephen Hales in the eighteenth century, a
hemostat, also called a
hemostatic clamp is a
surgical tool which resembles a set of
scissors with a locking clamp replacing the blade. A set of hemostats comes in several different sizes and types, for example,
Kelly,
Crile, and
Halsted; and any given surgery may require the use of a number of hemostats.
A hemostat is commonly used in both
surgery and
emergency medicine to control
bleeding, especially from a torn blood vessel, until the bleeding can be repaired by sutures or other surgical techniques. The process of halting bleeding is called
hemostasis.
Hemostats are part of the
first aid kit carried by
combat lifesavers and
paramedics.
Another "hemostat" has been used in the surgical field. The microfibrillar
collagen hemostat (MCH) is a topical agent composed of resorbable microfibrillar collagen. It attracts platelets and allows for the formation of a blood clot when it comes into contact with blood. Unlike the hemostatic clamp, no mechanical action is involved. The surgeon presses the MCH against a bleeding site and the collagen attracts and helps with the clotting process to eventually stop bleeding.
The practical application for MCH is different from that of the hemostatic clamp. It isn't possible, for example, to stop a severed artery from gushing blood by using a patch of MCH and wait for the clotting process. The blood vessel must be mechanically clamped and repaired.
