Disposable cytology brushes – advantages and features

Cytologic examination of tissues is necessary whenever pathological changes in the mucous membrane are detected during an endoscopic examination. This allows us to accurately determine the nature of the lesion - inflammation, benign or malignant cell proliferation.

It is important that the tissue sample is not damaged during the analysis, as this greatly complicates the cytology examination. It is also necessary that such a procedure does not harm the patient and does not provoke bleeding, inflammation, or infection of the mucous membrane.

The doctor obtains tissue by scraping and uses disposable cytology brushes. Disposable instruments have the advantage of not requiring sterilization, and there is no risk of infecting a person with serious diseases (viral hepatitis B, C, HIV infection).

Single use cytology brushes for endoscopy are packed in a sterile container, thus eliminating infection at any stage of endoscopic manipulation. After scraping, they are disposed of and cannot be reused or disinfected.
