biopsianyöriä

Biopsianyöriä, also known as biopsy strings or biopsy threads, are thin, flexible threads made of absorbable or non-absorbable materials used in certain medical procedures. Their primary function is to mark a biopsy site or to aid in the retrieval of tissue samples. In some cases, they might be used to identify specific areas within a larger tissue sample that require further examination or analysis. The material and thickness of the biopsy string can vary depending on the intended application and the preference of the medical professional.

These threads are typically sterile and designed for surgical use. They can be introduced into the body during a biopsy procedure, often alongside the biopsy needle or instrument, to provide a clear visual or tactile reference point. This marking is particularly useful for radiologists and surgeons when re-locating a lesion for follow-up imaging or treatment. In interventional radiology, biopsy strings can sometimes be left in situ after a biopsy to guide subsequent procedures. The choice between absorbable and non-absorbable materials depends on whether the string needs to remain in the body long-term or if it is intended to be removed or dissolve on its own. The use of biopsy strings aims to improve the accuracy and efficiency of diagnostic and therapeutic interventions.
