Description

Technical Field

[0001] The utility model relates to the technical field of biological tissue embedding machines, in particular to an operating device used for sample embedding. Background Art

[0002] An embedding machine, also known as a biological tissue embedding machine or paraffin embedding machine, is a medical device that embeds human or animal and plant specimens after dehydration and wax immersion into paraffin for histological diagnosis or research after sectioning. The principle is to place the biological tissue block in melted paraffin, fix it with paraffin, and then use a microtome to cut the tissue into thin slices for research use.

[0003] Publication No. CN219890878U discloses a biological tissue embedding machine. The device uses an electric telescopic rod in a lifting mechanism to drive a curved block to move. The curved block drives a roller to rotate. The roller drives a T-shaped column to slide inside the embedding machine body. The T-shaped column compresses a spring, and the T-shaped column drives a placement plate to rise. The placement plate drives the mold to rise below the wax flow nozzle. When embedding biological tissue, the biological tissue embedding machine body is configured to drive the mold to move below the wax flow nozzle, shortening the distance between the two. The paraffin liquid does not splash onto the surface of the embedding machine body, nor does it cause contamination of the embedding machine surface. However, the following problems still exist in actual use of this patent:

[0004] The device is installed inside the pipeline through a filter, and both ends of the support plate are fixedly connected to the surface of the support frame, so that the filter can filter the melted wax inside the wax storage box to prevent impurities in the melted wax from contaminating biological tissues. The support plate can enhance the strength of the support frame, but the device does not have a filter cleaning function, so the filter is easily clogged by impurities in the wax, affecting the wax discharge efficiency. As a result, the staff need to frequently disassemble and clean the filter inside the pipeline, which greatly reduces the maintenance efficiency of the device and brings inconvenience to the staff when using it.

[0005] The present invention proposes an operating device for sample embedding in order to solve the above problems. Utility Model Content

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an operating device for sample embedding, comprising an embedding machine body, a support plate mounted on one side of the top end of the embedding machine body, a wax storage box disposed on the top end of the support plate, and a wax flow nozzle disposed at the bottom end of the wax storage box; a cleaning mechanism disposed inside the top end of the support plate, and a pushing assembly disposed on one side of the support plate;

[0008] Among them, the cleaning mechanism includes a square tube installed inside the top of the support plate, and a filter is installed on one side of the interior of the square tube, and a reciprocating screw is rotatably connected to the interior of the top of the square tube, and the outer side of the reciprocating screw is threadedly connected to the cleaning plate, and a brush plate is installed at the bottom end of the cleaning plate, and a motor is installed at one end of the reciprocating screw, and a screen frame is inserted into the interior of one side of the square tube, and a sealing plate is installed on one side of the screen frame, and a fixed box is symmetrically installed on one side of the square tube, and a pulling frame is slidably connected to the interior of one end of the fixed box, and an insert is symmetrically installed on one end of the pulling frame, and the insert is gap-matched with the screen frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the operating device for sample embedding is as follows: the staff starts the motor to drive the rotation of the reciprocating screw, and the movement of the cleaning plate drives the brush plate to move back and forth on the surface of the filter screen, and then the staff inserts the screen frame into one side of the square tube, so as to achieve the effect of rapid reciprocating cleaning of the filter screen, thereby effectively avoiding the phenomenon that impurities in the wax clog the filter screen and cause the wax to be discharged unsmoothly, improving the sample processing efficiency of the device, and the movement of the brush plate can sweep the filtered impurities into the interior of the screen frame, thereby achieving the effect of concentrated collection of impurities, and then facilitating subsequent staff to clean the filter screen.

[0016] 1. The staff starts the motor to drive the rotation of the reciprocating screw, and the rotation of the reciprocating screw drives the movement of the cleaning plate. The movement of the cleaning plate drives the brush plate to move back and forth on the surface of the filter. Then the staff inserts the mesh frame into one side of the square tube.

The filtered impurities are centrally processed, which greatly improves the daily maintenance efficiency of the device by the staff, reduces the frequency of the filter cleaning by the staff, and brings convenience to the staff when using it. By moving the pulling frame to slide inside the fixed box, the distance between the first rotating seat and the second rotating seat changes. At this time, the retractable rod and the telescopic spring are retracted. By loosening the pulling frame and then the resetting property of the telescopic spring, the plug-in block and the screen frame can be plugged and fixed, so that the screen frame can be quickly installed and disassembled, which is convenient for the staff to clean the impurities inside the screen frame later, which brings practicality to the staff when using it.

[0017] 2. The staff rotates the rotating disk to drive the rotation of the screw, and the rotation of the screw drives the threaded sleeve to slide inside the sliding box. At this time, the threaded sleeve drives the push plate to slide inside the bottom end of the sliding box. At this time, the threaded sleeve drives multiple groups of balls to roll with the chute, so that the sample mold on the embedding machine body can be pushed to the ice table. The rolling connection between the balls and the chute greatly reduces the resistance encountered by the threaded sleeve when moving, thereby making the movement of the push plate more stable, greatly improving the staff's operation efficiency of the push plate, and compared with the existing technology using powered equipment to drive, the use cost is lower, meets the use needs of small workshops, and brings convenience to the staff when using it.
