Description

Technical Field

[0001] The invention relates to the technical field of living tissue slicer equipment, and in particular to a pathological tissue cutting device. Background Art

[0002] Pathological tissue cutting refers to taking a certain size of diseased tissue, making pathological sections using pathological histological methods (usually embedding the diseased tissue in a paraffin block, cutting it into thin slices with a slicer, and then staining it with hematoxylin-eosin), and further examining the lesions with a microscope. However, the inventors have found that the current pathological tissue slicers are not able to fix the tissue adequately when slicing living tissue, and the posture of the tissue shifts when cutting. In addition, since the tissue is immersed in wax and embedded during embedding, the high temperature during slicing causes defects such as several small cracks or fissures in uncertain positions to appear on the sliced ​​sample. Therefore, those skilled in the art have proposed a solution for pathological tissue cutting equipment. Summary of the invention

[0003] In view of the above background technology, it is pointed out that the current pathological tissue slicer is not able to fix the tissue sufficiently when slicing living tissue, and the tissue is displaced when cutting. There are several small cracks or fissures in uncertain positions on the slice, so a technical solution of a pathological tissue cutting device is provided.

[0004] It includes a slicing mechanism, a pathological tissue placement table is arranged on the front area of ​​the top surface of the slicing mechanism, two pathological tissue flexible clamps are movably arranged on the top surface of the pathological tissue placement table, and a pathological tissue cooling system is fixedly connected to the bottom surface of the pathological tissue placement table;

[0005] The slicing mechanism includes two bases arranged on the left and right, a bottom plate fixed to the upper surface of the base, and a shell fixed to the right side of the rear surface of the bottom plate, a saw blade driver is fixedly connected to the rear side of the shell, and a cutting saw blade adapted to the saw blade driver is arranged on the front side of the shell;

[0006] The pathological tissue flexible clamp includes a hanging plate, a U-shaped bracket fixed to the rear side of the hanging plate, and two half-circle gears connected to the front side of the U-shaped bracket in a left-right mirror-symmetrical rotation. A servo motor is installed on the bottom surface of the hanging plate, and the output shaft of the servo motor is connected to a driving gear through a coupling. Specifically, before cutting the pathological tissue, the servo motor and the driving gear drive the half-circle gear to rotate, and the pulling rod is opened outward, forcing the clamping arms to open outward away from each other, and the pathological tissue is placed between the clamping arms. After the servo motor rotates in the opposite direction to clamp the pathological tissue, the slider on the electric control rail is moved back and forth to allow the pathological tissue to contact the feeding guide plate. If the pathological tissue is small, the slider is moved closer or farther away from each other on the electric control rail before clamping the pathological tissue to adjust the size of the pathological tissue.

[0007] The pathological tissue placement table includes a movable block slidably arranged on the upper surface of a bottom plate, a movable plate fixed on the upper surface of the movable block, and a side vertical plate fixedly connected to the left side of the upper surface of the movable plate, the top surface of the side vertical plate is fixedly connected to an electric control guide rail, two sliders are movably arranged on the track of the electric control guide rail, and a support plate is fixed on the top of each slider, and the end of the support plate away from the slider is fixedly connected to the front side surface of the hanging plate; specifically, the pathological tissue to be cut is placed on the upper surface of the movable plate, the rear end of the tissue is allowed to contact the front surface of the feeding guide plate, and the feeding guide plate is pulled forward or backward by adjusting the rotation of the screw rod, so that after the cutting saw blade is driven by the saw blade driving machine, the forward and backward moving distance of the feeding guide plate controls the slice thickness of the tissue.

[0008] The pathological tissue cooling system includes a shell fixed on the left side of the movable block, a fan fixed in the inner cavity of the shell, and a rectangular frame fixed on the upper surface of the shell, a heat-conducting coil is fixedly connected to the inside of the rectangular frame, a vortex tube is horizontally passed through the inside of the heat-conducting coil, and a servo air pump matched with the vortex tube is fixedly connected to the front surface of the rectangular frame. Specifically, when the movable plate slides left and right on the slideway by the movable block for slicing, the servo air pump provides flowing air to the inside of the vortex tube, and the low temperature is transferred to the heat-conducting coil after being cooled by the vortex tube. Since the upper surface of the heat-conducting coil is in contact with the bottom of the movable plate, and the pathological tissue is placed on the movable plate, the wax embedded in the pathological tissue is affected by the low temperature and solidifies, thereby preventing cracks or cracks from appearing on the sample after slicing.

If the pathological tissue is small, the slider 34 is moved closer or farther away from each other on the electric control guide rail 33 before clamping the pathological tissue to adjust the size of the pathological tissue.
