Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to an endoscopic specimen sampling rapid fixing device and an application method thereof. Background Art

[0002] At present, when collecting endoscopic specimens, such as using biopsy forceps or snares to collect specimens, they cannot be placed in formalin fixative in time, which causes the specimens to be exposed to the air for a long time and the tissue structure to change. Especially when multiple specimens are taken from the same part of the same patient or from different parts at the same time, the specimens are placed on the operating table, and specimen confusion may occur. This has always been a major problem in clinical endoscopic specimen management.

[0003] Moreover, when endoscopic nurses collect specimens, their hands are contaminated due to holding instruments. When collecting multiple specimens, they need to take off the contaminated gloves and perform hand hygiene before they can fix the specimens in the fixative in time. If the specimen bottle is opened in advance, this will cause the formalin fixative to be exposed to the air. The exposure time is related to the sampling time (which varies in length depending on the patient's condition), glove removal time, hand hygiene time, etc.

[0004] Currently, existing equipment can only solve the problem of collecting specimens after endoscopic tissue resection. The existing device connected to negative pressure to collect specimens needs to be cleaned and disinfected; the existing endoscopic tissue specimen classification device only performs classification and cannot solve the problem of specimen exposure to the air.
