Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a medical pathology slicer and a method for making pathology slices using the slicer. Background Art

[0002] Pathological sections are physical specimens for observation under a microscope, which are taken from the diseased tissue of the diseased body and processed through a specific process during the pathological diagnosis of the patient during the operation. In modern medicine, especially in the diagnosis of tumors, pathological sections are an indispensable and important link. Pathological sectioning machine is the key equipment for making sections, and its performance and accuracy are directly related to the quality of specimen preparation of diseased tissue and the work efficiency of pathologists.

[0003] Traditional pathology slicers are mostly semi-automatic handwheel-type slicers. When slicing the object, it is mainly done through the action of "cutting". Its working principle is that the large handwheel on the right rotates to drive the specimen tissue to move up and down, and there is another small handwheel on the left to make the specimen tissue move forward and backward quickly, combined with the function of the knife holder to achieve the function of slicing. Although it has the characteristics of high work efficiency, the purely mechanical motion feeding principle makes the slicing process more laborious, mechanical collisions produce various noises, and the complex internal mechanism makes the machine have a high failure rate and difficult maintenance.

[0004] In addition, since the force direction of the blade is mainly along one side of the object being cut, it is mainly an extrusion movement at the microscopic level. Therefore, the cell tissue on the slice section will be subjected to greater and uneven force, resulting in a certain degree of tearing, thereby affecting the microscopic cell tissue structure of the slice section and having an adverse effect on pathological analysis. Summary of the invention

[0041] A PLC control system is arranged in the electric control box, and the PLC control system is electrically connected to the drive motor of the object to be cut, the drive motor of the upper pressure plate, the drive motor of the cutting blade and the vibrator of the cutting blade respectively.

[0042] Specifically, the slicing operation box 11 has an upper and lower opening structure, the upper pressure plate is arranged at the upper opening of the slicing operation box, and an upper pressure plate balance adjustment rod 14 is installed at the four corners of the top of the upper pressure plate. The upper pressure plate balance adjustment rod is connected to the upper pressure plate balance adjustment plate 15, and the upper pressure plate balance adjustment plate is connected to the upper pressure plate transmission mechanism 18.

[0043] Specifically, the bottom of the upper pressing plate 12 is provided with conical protrusions 12 - 1 covering the entire surface of the plate, and a plurality of pressure sensors 20 are installed at the center of the bottom of the upper pressing plate.

[0044] Specifically, the object transmission mechanism 4 includes: an upper pressure plate drive motor 19 installed on the object transmission mechanism mounting plate, a screw bracket, a screw and a linear axis, the output shaft of the upper pressure plate drive motor is connected to the screw through a motor connecting shaft, the screw bracket is fixedly connected to the object transmission mechanism mounting plate, a screw and a linear axis parallel to each other are installed on the screw bracket, a screw nut moving along the axial direction of the linear axis is provided on the screw, and screw bearings are respectively installed at both ends of the screw.

[0048] The method for making pathological sections using the above-mentioned medical pathological section machine comprises the following steps:

[0049] S1. The operator first sets the slice thickness and the number of slices as required, and inputs them into the electric control box through the touch screen 22.

[0050] S2, then placing the object to be cut at the center of the object-carrying plate 10 in the slicing operation box 11, and setting the running speed and stroke of the cutting blade according to the scale mark on the object-carrying plate;

[0051] S3, starting the object drive motor 13 of the medical pathology slicer, and pushing the object support plate 10 upward through the object transmission mechanism 4;

[0052] S4, start the upper pressing plate driving motor 19 of the medical pathology slicer, make the upper pressing plate transmission mechanism move downward, and push the upper pressing plate downward and press the sliced ​​object. The downward distance of the upper pressing plate is exactly the set slice thickness. For example, the slice thickness is set to 5mm. When the upper pressing plate moves downward and presses the sliced ​​object, it can stop moving downward.

At this time, the cutting blade drive motor 8 and the cutting blade transmission mechanism 26 of the medical pathology slicer are started, and the cutting blade 23 is driven to move forward in the horizontal direction of the object to be cut. At the same time, the cutting blade vibrates left and right under the action of the cutting blade vibrator 25 to implement the cutting operation of the object to be cut.

[0055] S7. When the cutting blade reaches the set stroke, the cutting blade stops cutting, and the cutting of a pathological section is completed.

[0056] S8, the operator starts the upper pressing plate driving motor on the slicing operation box again, so that the upper pressing plate transmission mechanism moves upward and returns to the original position, and the cutting blade automatically returns to the original position, and the pathological slices can be taken out at this time.

[0057] Since the cutting blade moves horizontally and vibrates during cutting, it can avoid the cell tissue on the slice section being subjected to large and uneven force, which may cause a certain degree of tearing, thereby ensuring the integrity of the microscopic cell tissue structure of the slice section and improving the cutting accuracy.

[0058] The medical pathology slicer combines the advantages of mechanical and electronic control systems to automatically slice the object to be sliced, improve the slicing efficiency, reduce the extrusion damage to the cell tissue structure of the sliced ​​section caused by the pathology slicer in the prior art, and is beneficial to pathological analysis.
