Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments and relates to a digestive endoscope biopsy cap. Background Art

[0002] The biopsy cap is used for the biopsy port of an endoscope (such as a digestive endoscope) to seal. When a biopsy operation is not being performed, it is usually closed to maintain the air pressure in the digestive tract cavity. When a biopsy operation is being performed, the biopsy instrument is operated by directly piercing the biopsy cap. The sealing cover on the existing digestive endoscope biopsy cap will lose its sealing effect after being pierced multiple times. Since the cap body and the sealing cover on the existing digestive endoscope biopsy cap are manufactured or connected together, even if the cap body is partially intact, it will be discarded together with the sealing cover that has lost its sealing effect, resulting in a waste of resources. There is a large room for improvement. Summary of the Invention
