Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a frozen sample tray with a mark. Background Art

[0002] Frozen section is a method of rapidly cooling tissue to a certain hardness under low temperature conditions and then slicing it. Because its production process is faster and simpler than paraffin section, it is often used for rapid pathological diagnosis during surgery. There are many types of frozen sections, including low-temperature constant-temperature freezer frozen section method, carbon dioxide frozen section method and methanol cycle refrigeration frozen section method. With the changes of the times and the development of science and technology, these methods were considered very important technologies many years ago, and have gradually been eliminated. Of course, some technologies, such as low-temperature constant-temperature freezer frozen section method, are receiving attention.

[0003] Frozen section pathological diagnosis is to quickly freeze the excised diseased tissue in a freezing microtome and make slices, and the pathologist will quickly make a pathological diagnosis. Generally, the patient needs to wait on the operating table for about 30 minutes. After the diagnosis result is reported, the surgeon will decide whether to perform further surgical treatment on the patient. Through freezing, the benign or malignant nature of the tumor can be determined to determine the surgical plan. The spread of malignant tumors can be understood, including whether the tumor has infiltrated adjacent tissues, whether there is regional lymph node metastasis, etc.; it can also determine whether there is any residual surgical margin, and what tissue was removed, such as fallopian tubes.

[0004] Frozen diagnosis requires pathologists to have considerable experience and the ability to make decisions quickly under pressure, so frozen diagnosis is relatively more technically demanding and has greater responsibilities. Frozen diagnosis in the pathology department determines the surgical method for surgical patients. With the development of modern medicine, the number of frozen sections is increasing. In order to improve the efficiency of diagnosis, multiple pieces of tissue or several frozen tissues are often sent for examination at the same time. Since the frozen sample tray itself has no identification function, there is a serious medical accident of "mistaking the diagnosis" due to the wrong sample head. In order to prevent the wrong sample head from being replaced, the earliest method used was to distinguish sample heads with different colors. This can only be used for tissues that do not need to be distinguished in the same case. There is also a risk of misremembering between different cases, so few people use this method for identification now. The most commonly used method is to stick a label with the frozen number on the sample head. This label is more troublesome to stick when used. The glue (or embedding agent) will stick to the hands, and the paper made of self-adhesive material will stick to the gloves. The label may be lifted and cut off during slicing. Especially when there are a large number of sample heads, technicians will not use it because of time constraints. Therefore, how to use a simple, convenient, fast and efficient method to complete the freezing operation is the key to solving this problem. Utility Model Content
