tähystysneulan

Tähystysneula is a Finnish term referring to a biopsy needle used during endoscopic procedures. Endoscopy involves inserting a flexible tube with a camera, known as an endoscope, into the body to visualize internal organs and tissues. When a suspicious or abnormal area is identified during an endoscopic examination, a tähystysneula is employed to obtain a tissue sample for further analysis.

The tähystysneula is a specialized needle designed to pass through a working channel within the endoscope. This allows the physician to access and sample the target tissue without requiring a separate incision. The needle typically has a sharp tip to penetrate tissue and a hollow lumen to retrieve a small specimen. Different types of tähystysneulat exist, varying in size, gauge, and design, depending on the specific endoscopic procedure and the type of tissue to be sampled.

The retrieved tissue sample is then sent to a pathology laboratory where it is examined under a microscope by a pathologist. This examination helps in diagnosing various conditions, including cancer, inflammation, or other abnormalities. The use of a tähystysneula during endoscopy is a minimally invasive technique that provides crucial diagnostic information, guiding subsequent treatment decisions. It is a standard tool in gastroenterology, pulmonology, and other medical specialties that utilize endoscopic procedures.
