AI Technical Summary

Technical Problem

In the existing technology, the drying process of liver cancer biopsy specimens adopts a single method, which results in excessively long drying time for specimens with high water content or special texture, affecting the detection efficiency and potentially causing unevenness, thus interfering with the pathological test results.

Method used

A specimen preparation and testing device for liver cancer biopsy was designed. It uses a warm air blower in the heating box to deliver hot air for preliminary preheating and uniform heating. Combined with a heating plate driven by a threaded rod and an oscillating mechanism, it can achieve multi-angle heating and uniform drying of the specimen. The specimen is then transported to the testing rack by a conveyor belt for pathological testing.

Benefits of technology

It improves the efficiency and accuracy of specimen drying, ensures the reliability of pathological testing, reduces human error, and provides efficient testing conditions.

Abstract

The invention discloses a sample preparation and detection device in liver cancer biopsy, and relates to the technical field of sample preparation and detection, the sample preparation and detection device comprises a table top, the upper surface of the table top is provided with a detection frame for detecting a sample, and the front side of the table top is provided with a conveying belt for adjusting the position of the sample; and a heating box for drying the dyed specimens is fixedly connected above the conveying belt. According to the sample preparation detection device in the liver cancer biopsy operation, the air pressure in the adjusting box can be changed through the intermittently-started warm air blower, when the warm air blower is started, the air pressure in the adjusting box is increased, the spherical spraying pipe rotates around the air supply pipe, the air spraying direction is changed, and large-range heating treatment on the interior of the heating box is achieved; the air pressure in the adjusting box is reduced, under the action of the reset spring, the spherical spray pipe also restores to the initial position, and the circulation is repeated, so that the heat distribution in the heating box is more uniform under the action of the swing mechanism, and the drying effect and efficiency of sample preparation are improved.
