Description

ESD postoperative sample fixing device based on magnetic force

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to ESD postoperative sample fixing device based on magnetic force.

Background

Tumors are one of the major diseases threatening human health. Gastrointestinal tumors can be removed by surgical operation, and early gastrointestinal tumors (which are predicted to be only infiltrated into a mucosal layer or a submucosal layer) can be treated by enteroendoscopic mucosal resection (ESD). The pathological diagnosis of the ESD postoperative specimen is different and higher in requirement compared with the common pathological diagnosis. It requires that all samples after ESD excision be obtained, and a pathological section is made every 2mm width. The fixation of the excised specimen requires flattening and no adhesions or folds to allow the patient to search for every corner where early lesions may be present. Therefore, the fixation of the ESD postoperative specimen plays a crucial role in the preparation and diagnosis of pathological specimens, and is a prerequisite for improving the diagnosis of early gastrointestinal tumors. The fixing effect is good, the specimen fixing liquid is beneficial to soaking, the specimen dyeing and the diagnosis of pathologists and the domestic and foreign communication of pathological sections.

At present, a rubber plate or a foam plate is used as a fixing support for an ESD specimen, and a pin is used for pricking the periphery of a mucous membrane into the rubber plate or the foam plate so as to achieve the purpose of flattening. The specimens were then immersed in round bottles or square boxes of PP material containing 10% formalin fixation solution.

If the glue is a rubber plate, the rubber plate is at the bottom, the mucous membrane is in the middle, and the stationary liquid is above; in the case of foam boards, the boards are inverted in fixative, i.e., foam board above, mucous membrane in, fixative below. Because the rubber plate or the foam plate can not allow the fixing liquid to penetrate, the mucous membrane tightly attached to one side of the plate is often poor in fixing effect. The rubber plate is larger, so that the phenomenon of fixed liquid waste is often caused.

Although the foam board is placed upside down in the small round bottle and can save stationary liquid, the foam board is cut by a doctor manually, and the foam board is clamped on the round bottle often because of being cut into a polygon, so that a specimen cannot be contacted with the stationary liquid, and the purpose of fixing the specimen is not achieved. Sometimes, a doctor can clamp the specimen in a round bottle by using a foam plate below and a pin above and relying on the force of the pin, so that the clamping cannot be guaranteed, and the specimen cannot be soaked below the liquid level all the time. If the specimen can not be fixed sufficiently immediately after being separated from the body, certain proteins in the mucous membrane can be degraded, certain immunohistochemical detection indexes related to later treatment can not be expressed accurately, and the fixation in the later specimen preparation process can not be compensated.
