Description

Digestive endoscopy biopsy cap

Technical Field

The invention relates to the technical field of medical equipment, in particular to a digestive endoscopy biopsy cap.

Background

Biopsy, which is called biopsy, also called surgical pathology examination, and called external examination for short; means a technique for taking out a lesion tissue from a patient body by cutting, clipping or puncturing, etc., and performing pathological examination, as required for diagnosis and treatment; it is the most important part of the diagnosis pathology, and it can make clear histopathological diagnosis for most of the examined cases, and it is used as the final diagnosis in clinic. The biopsy cap is used on a biopsy port on the endoscope and plays a role in sealing; when the biopsy operation is not performed, the biopsy instrument is always in a sealing state to stabilize the air pressure in the cavity of the digestive tract, and when the biopsy operation is performed, instruments such as a biopsy needle are inserted through a biopsy cap, but the sealing performance is easily reduced, so that substances such as body fluid and the like in the internal environment of a patient are sprayed out, the surgical environment and the instruments are polluted, and the operation of a doctor is inconvenient; to this end we propose a digestive endoscopy biopsy cap.
