Description

Thin needle puncture biopsy sample save set

Technical Field

The utility model belongs to the technical field of thin needle puncture biopsy sample preserves, especially, relate to a thin needle puncture biopsy sample save set.

Background

At present, the thin needle aspiration biopsy specimen is generally contained in the specimen bottle that has specimen preservation liquid under the guide of supersound scope and is preserved, the specimen bottle specification is mostly diameter 3cm, the cylindrical plastic bottle of height 4cm, can adorn specimen preservation liquid in it, the screw thread is rotatory uncapped, when the specimen is only used for the diagnosis, earlier on the tissue is as for the slide, measure or the naked eye aassessment specimen length with outside ruler, again with complete (strip) specimen immigration in the specimen preservation bottle that contains formalin, the piece (small fragment, incomplete) specimen that will remain on the slide is used for the smear, temporarily store in the slide preservation box that contains alcohol, again be used for pathological diagnosis with these two parts of specimen.

However, with the development of precise medical treatment, diagnosis is not the only purpose for obtaining a tissue specimen of a patient, and the tissue specimen can also be used in the aspects of primary cell culture, organoid culture, xenotransplantation and the like, namely, preclinical disease research models are constructed, and the models not only can assist diagnosis, but also can guide the formulation of a treatment scheme. The construction of preclinical disease research models presupposes the presence of a sufficient and contamination-free specimen, and therefore, the length of the specimen after it is obtained needs to be measured and kept sterile. The prior art is to place the specimen on a glass slide, measure the specimen with a ruler, and then transfer the specimen into a specimen bottle for storage. Such separation of measurement and preservation may result in specimen contamination, and may not be possible to remove all specimens (with fragmented specimens remaining on the slide) when removing them into the specimen vial, resulting in specimen loss.

In summary, there is a need for improvements to existing specimen containment structures.
