Lancet

A lancet is a small, sharp, pointed, two-edged surgical instrument used for making incisions, typically to release blood or other fluids. Traditionally, lancets were used extensively for bloodletting, a practice now largely obsolete. Modern lancets are usually disposable and designed for finger-pricking to obtain small blood samples for diagnostic testing, such as blood glucose monitoring for diabetics. They are a crucial tool in healthcare for various procedures where a small puncture is necessary.

Lancet meaning with examples

• The phlebotomist carefully selected a sterile lancet to draw a blood sample for the patient's routine check-up. She explained the procedure, assuring the patient it would be quick and relatively painless. Using a spring-loaded device, the lancet made a tiny incision, allowing a small amount of blood to flow into the collection tube. This quick procedure facilitated the accurate analysis of blood samples at the lab.
• Diabetics are often required to use lancets multiple times daily to monitor their blood sugar levels. The device offers a small and discreet form factor for easy usage. The user gently pricks their fingertip to obtain a small drop of blood. This sample is then placed on a test strip, which is read by a glucose meter to provide accurate blood sugar readings. The process is vital to helping diabetics manage their disease.
• In historical medical practices, lancets were essential tools for bloodletting, a therapy used to treat various ailments. The surgeon would use the lancet to incise a vein or artery, believing that removing 'bad' blood would restore the body's balance. This practice, though once widespread, has now been mostly replaced with more modern methods. The lancet's use has evolved substantially in response to better medical understanding.
• During the minor surgical procedure, the surgeon reached for a lancet to make a precise incision. The sharpness of the lancet allowed for a controlled cut with minimal tissue damage. After the incision, the surgeon could proceed with the procedure, which went smoothly. Proper sterilization of the lancet before use was critical to avoid infection and ensure the patient's wellbeing.
