Description

A operation sample storage device that is used for embedding mucosa to peel off art under scope

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an operation specimen storage device for an embedded endoscopic mucosal dissection.

Background

Digestive tract tumors are the top ten tumors of the major cause of death in humans. Malignant tumor with seventh incidence rate and sixth death rate of esophageal cancer; gastric cancer is a malignant tumor with the third morbidity and the fourth mortality in China; intestinal cancer is the second-most and fifth-most incidence of digestive tract malignancy. Therefore, the method has important significance for improving the early diagnosis rate of the digestive tract tumor. Endoscopic Submucosa Dissection (ESD) can be used not only as a means for diagnosing digestive tract diseases, but also for directly dissecting mucosa and lesions under an endoscope, thereby achieving the effect of treatment. The stripped mucosa can be used for pathological diagnosis of pathological changes and subsequent treatment. Compared with the traditional major surgery, the ESD has the advantages of being minimally invasive, keeping the original digestive organs while removing the lesion, carrying out multiple treatments on the same part, obtaining complete specimens for pathological diagnosis, carrying out more than 96% of removal rate on tumors with large areas, irregular shapes or combined ulcers and scars, low in recurrence probability and the like.

Embedding is an important part in the preparation process of pathological sections, and the tissue embedding box also has wide application in the preparation link of pathological sections. Embedding is the process of encapsulating the tissue to be embedded with an embedding agent such as paraffin to provide performance support or chemical protection. At present, the mode of taking materials for the ESD operation specimen to be inspected in the pathology department is to make parallel sections at intervals of 2cm, and put tissues in an embedding box in sequence for slicing so as to determine the deepest infiltration depth of a focus. However, the tissue embedding boxes commonly used in China at present are limited in length and width, and for a relatively large ESD operation specimen, a long tissue cannot be unfolded flatly and linearly, so that the long tissue is divided into tissues with proper lengths by cutting, and then the tissues are placed in the embedding boxes for a series of subsequent operations. If two sections are divided, the broken ends can be marked by selecting a mode of coating biotin ink on one section of the tissue. However, the method has the disadvantage that the biotin ink can be dispersed to the opposite side or washed away in the dehydration process, so that the broken ends and edges cannot be clearly distinguished, and the subsequent pathological diagnosis under a microscope is greatly influenced. Sometimes, the tissue specimen is too large and needs to be divided into three sections, and the division is not clear. Even if the tissue is orderly arranged when the tissue is put in, the direction and the arrangement sequence of the tissue can be lost due to the flushing of the liquid in the dehydration process, and the subsequent pathological diagnosis of a pathologist is confused. The subsequent pathologist needs to restore the original whole tissue block according to the position of the whole tissue (as if a jigsaw is made by taking the material slices, the whole tissue block needs to be restored), then the position of the pathological change or canceration is marked on the original tissue block, and the information is provided for the endoscopist to restore the endoscopic image, so that the overall medical level and the early treatment rate of early diagnosis are improved. Therefore, after dividing into multiple pieces, the original tissue blocks are restored, and the sequence and the direction are not changed as much as possible, which is important for the technical improvement of the subsequent pathological diagnosis and the endoscopic diagnosis.

In addition, the diameter of the elongated hole of the tissue embedding cassette commonly used at present is too large for some minor ESD surgery standards, and some mucosal tissues with the thickness of less than 2 mm fall out of the embedding cassette through the hole gap, so that the tissue is lost, and therefore, the missed diagnosis or the misdiagnosis may be caused. In addition, for some important cancer tissue specimens, the tissue becomes fragile and shattered due to the characteristics of cancer cells, and is easily broken and lost, and the tissue may be bent and uneven after dehydration. Thus, there is a need for a filter paper or biomaterial filter that can flatten tissue without losing the wrapping.

In addition, at present, if a medical practitioner wants to use filter paper, the medical practitioner must manually cut the filter paper and then wrap the tissue with the filter paper, or a commercially available biomaterial filter membrane is cut into small pieces, but the medical practitioner needs to manually wrap the tissue, and a simple and quick method for instantly adhering the tissue together is urgently needed.

The embedding links are subject to dehydration and temperature changes, which can cause the tissues to shrink and change or even lose position and direction. Therefore, in the process of sending the ESD operation sample to be embedded, the position and the direction of the tissue are difficult to determine whether the tissue is fixed or not. As a gold standard, pathological diagnosis is a crucial ring in the diagnosis of gastrointestinal cancer. The ESD specimen for pathological diagnosis is the most basic raw material, and whether the ESD specimen is flat, whether the edge is clear, and whether the direction is correct is the basis for accurate pathological sampling and diagnosis. Therefore, the accuracy of pathological diagnosis is directly affected by whether the specimen is completely embedded.
