Description

Tissue sample storage method for oncology department

Technical Field

The invention relates to the field of medical instruments, in particular to a tissue sample storage method for oncology.

Background

Endoscopic procedures, including bronchoscopy, gastroscopy, enteroscopy, and the like, are commonly used as an access method by modern clinicians. The clinician observes the body cavity structure under the guidance of the built-in endoscope, when the suspicious focus is met, a plurality of small tissues are directly taken under the endoscope and sent to a pathology department for detection so as to determine the type of the lesion and further determine a treatment scheme.

During the storage and transportation process, the tissue specimen needs to be preserved to prevent the tissue from being polluted or denatured. Formalin in the existing tissue specimen tissue storage is still the first choice liquid medicine for tissue fixation, but formalin is a reducing agent, contains 4% of formaldehyde, is extremely volatile, and has carcinogenicity in the literature report. When fixing the tissue specimen after operation, the medical staff needs to put the specimen into the pathological specimen inspection bottle filled with formalin. Doctor protection is found to be problematic in clinical work when tissue specimens are fixed: that is every time the doctor puts into the specimen and send and examine the bottle the volatile gas of formalin will be inhaled, causes the injury to the health. If human skin is directly contacted with formalin, allergic reaction, dermatitis or eczema may be caused, and such phenomena are often caused especially for people who need to be contacted with formalin for a long time in work. Formaldehyde is very volatile, has strong irritation and injury to eyes, and can be used for treating eye diseases if formalin solution is contacted with eyes carelessly. If the medicine is inhaled carelessly, the medicine can stimulate mucous membrane tissues of mouth, nose and respiratory tract, pain and cough are caused slightly, the respiratory tract is inflamed seriously, and even pulmonary edema is caused. In recent years, occupational protection is more and more emphasized, but the conventional tissue specimen inspection bottle is difficult to protect because a tissue specimen is soaked in formalin and then taken out from a liquid medicine during inspection, and the liquid medicine directly contacts air and a human body in the process of access.
