Brush
Brush (Medical Term)
Brush (/brʌʃ/), in the medical context, refers to a tool or device with bristles, typically used in medical procedures for cleaning, scrubbing, or applying a substance. The term originates from the Old French brosse, meaning 'brushwood'.
Usage in Medicine
In medicine, a brush is often used in procedures such as endoscopies, cytological examinations, and biopsies.
Endoscopy
During an endoscopy, a brush may be used to clean the endoscope before and after the procedure. This ensures that the device is free from any contaminants that could potentially harm the patient or interfere with the procedure.
Cytology
In cytology, a brush is often used to collect cells from the body for examination under a microscope. This is known as a brush biopsy. The brush is gently scraped against the area to be tested, collecting a sample of cells that can then be analyzed.
Biopsy
A brush can also be used in a biopsy procedure to collect tissue samples. This is particularly common in procedures such as a bronchial brush biopsy, where a brush is used to collect cells from the bronchial tubes in the lungs.
