Description

TECHNICAL FIELD

[0001] The utility model relates to quick frozen section storage technical field especially, it is a kind of intelligent temperature control formula in situ tissue quick freezing device. BACKGROUND

[0002] Intraoperative quick frozen section diagnosis is very important in surgery, and pathologists need to quickly determine the nature of the lesion, such as benign or malignant, to determine the next surgical plan. However, the existing freezing equipment may have inconsistent freezing speed, resulting in delayed diagnosis or errors, which may be due to the technical differences of the operators or the unstable performance of the equipment itself.

[0003] Traditional methods may rely on the experience of operators, such as freezing time, temperature control, etc. In addition, the sampled tissues placed on the sampling table will face the risk of contamination, and different samples have different urgent needs, so uniform freezing reduces the diagnosis efficiency to a certain extent. These human factors can cause freezing lag time differences, which in turn affect the efficiency of frozen section preparation. In addition, the equipment may not have a standardized process, resulting in different processing times for different samples or uneven freezing, affecting the quality of the sections.

[0004] Moreover, with the continuous progress of medical technology, the processing requirements for biological tissue samples are becoming higher and higher. Fine management and targeted processing can bring great convenience to pathological analysis and diagnosis. Traditional freezing equipment and operation methods often cannot meet the needs of rapid freezing and targeted processing, so there is an urgent need for a device that can conveniently operate, quickly, and accurately freeze biological tissues. At the same time, in order to facilitate the management and use of tissue samples, an integrated device that combines storage and freezing functions is also needed. Such a device not only reduces the risk of tissue samples during transfer, but also improves the efficiency and accuracy of sample processing.
