Description

Technical Field

[0001] This utility model relates to the field of tissue grinding device technology, and in particular to a high-efficiency grinder for lung cancer tissue samples. Background Technology

[0002] In lung cancer tissue sample research, tissue grinding is a crucial preliminary step, and its effectiveness directly affects the accuracy and reliability of subsequent analyses.

[0003] Currently, there is a tissue grinder on the market, model GT50. In use, the tissue sample and grinding balls are placed in the same container, which is then placed on the vibrating frame of the grinder. The vibration of the frame causes the grinding balls inside the container to move, thus grinding the tissue sample. However, this grinder uses a single vertical oscillation method, which limits the contact pattern between the sample and the grinding balls during grinding. The force generated by the unidirectional oscillation is relatively singular, limiting its ability to disrupt the complex cellular structure and tight intercellular connections in lung cancer tissue, thus requiring improved grinding efficiency. To address these issues, this device designs a high-efficiency grinder for lung cancer tissue samples. Utility Model Content

[0010] A drive assembly, comprising a dual-axis motor, which is movably connected to the inner wall of the rocker frame, and a rocking cam is fixedly mounted on the end wall of the output shaft of the dual-axis motor.

Detailed Implementation

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] See attached document Figure 1-3 ,include:

[0027] The housing 10 has an installation chamber 12 inside. The top wall of the housing 10 has a limiting groove 13 that communicates with the inside of the installation chamber 12. The width of the limiting groove 13 matches the thickness of the rocker frame 20 to prevent the rocker frame 20 from swinging along the output shaft axis of the dual-axis motor 21.

[0028] The rocking mechanism includes a rocking frame 20 movably installed inside the mounting chamber 12; a plurality of second connecting springs 27 are fixedly installed on the side wall of the rocking frame 20, and the end of the second connecting spring 27 away from the rocking frame 20 is fixedly connected to the inner side wall of the mounting chamber 12; a plurality of third connecting springs 28 are fixedly installed on the bottom wall of the rocking frame 20, and the end of the third connecting spring 28 away from the rocking frame 20 is fixedly connected to the inner bottom wall of the mounting chamber 12.

[0029] A first connecting block 23 is rotatably mounted on the opposite side wall of the dual-axis motor 21, and a second connecting block 24 is rotatably mounted on the inner side wall of the rocker frame 20. A first connecting spring 25 is installed between the first connecting block 23 and the second connecting block 24.

[0030] A rotating arm 26 is rotatably mounted on the top wall of the dual-axis motor 21. The end of the rotating arm 26 away from the dual-axis motor 21 is rotatably connected to the top wall of the rocker frame 20. The rotating arm 26 provides support for the dual-axis motor 21, thereby improving the stability between the dual-axis motor 21 and the rocker frame 20.

[0031] The drive assembly includes a dual-axis motor 21, which is movably connected to the inner wall of the rocker frame 20. A rocking cam 22 is fixedly installed on the output shaft end wall of the dual-axis motor 21. The rocking cam 22 is installed on both output shaft end walls of the dual-axis motor 21.

[0032] When the rocking cam 22 rotates along the output shaft of the dual-axis motor 21 to the four positions of up, down, left, and right, the rocking frame 20 is driven to make corresponding displacements.

[0033] The clamping assembly includes a fixed frame 30 fixedly installed on the top wall of the rocking frame 20. The fixed frame 30 is provided with a locking element, which includes a screw 31 threadedly connected to the fixed frame 30. A pressure plate 32 is installed at the bottom end of the screw 31. A groove 33 is provided on the top wall of the rocking frame 20. The container 40 can be placed inside the groove 33 so that the pressure plate 32 can press and fix the container 40 inside the groove 33. When fixing the container 40, the container 40 can be placed inside the groove 33, and then the screw 31 can be rotated clockwise to move the screw 31 downward. After the screw 31 moves, it drives the pressure plate 32 to move. After the pressure plate 32 moves, it presses against the outer wall of the container 40, thereby fixing the container 40 to the rocking frame 20.

[0034] The top wall of the box 10 is also connected to the box cover 11 by a hinge.

[0035] In this embodiment, the working principle of the device is as follows: when grinding lung cancer tissue samples, first open the box cover 11, place the container 40 containing the lung cancer tissue sample and grinding balls in the groove 33 on the top wall of the shaking frame 20, and rotate the lead screw 31 to drive the pressure plate 32 to move downward, thereby firmly squeezing and fixing the container 40 in the groove 33, ensuring that the container 40 will not shake or shift during the grinding process.

[0036] Next, the dual-axis motor 21 is started, and the output shaft of the dual-axis motor 21 begins to rotate. Since the rocking cam 22 is fixedly installed on the end wall of the output shaft of the dual-axis motor 21, the rocking cam 22 also rotates synchronously as the output shaft rotates. When the rocking cam 22 rotates along the output shaft of the dual-axis motor 21 to four different positions (up, down, left, and right), it will apply forces in different directions to the rocking frame 20.

[0037] During this process, the second connecting spring 27 on the side wall of the rocker frame 20 and the third connecting spring 28 on the bottom wall play the role of buffering and assisting in reset. When the rocker cam 22 pushes the rocker frame 20 to move in a certain direction, these springs will undergo elastic deformation and store elastic potential energy. When the force disappears, the springs release elastic potential energy to help the rocker frame 20 return to its initial position so that it can receive the next push from the rocker cam 22.

[0038] Meanwhile, the structure consisting of the first connecting block 23, the second connecting block 24, and the first connecting spring 25, together with the rotating arm 26, works together to ensure that the rocker frame 20 moves smoothly and steadily in all directions. The first connecting spring 25 can buffer and fine-tune the rocker frame 20 during displacement, preventing the displacement process from being too abrupt. The rotating arm 26 provides stable support for the dual-axis motor 21, enhancing the stability of the connection between the dual-axis motor 21 and the rocker frame 20. This makes the entire structure more stable and reliable when the dual-axis motor 21 drives the rocking cam 22 to rotate and pushes the rocker frame 20 to move.

[0039] During the shaking motion of the shaker 20 in the up, down, left, and right directions, the container 40 fixed on the shaker 20 also shakes. This multi-directional shaking causes the grinding balls inside the container 40 to generate more complex and diverse collision and friction movements with the lung cancer tissue sample. Compared with the traditional single vertical oscillation method, the rich shaking trajectory of this device allows the grinding balls to come into more comprehensive contact with all parts of the sample, and the generated forces are more diverse. This can more effectively destroy the complex cell structure and tight junctions between cells in the lung cancer tissue, thoroughly grind the tissue sample, and greatly improve grinding efficiency.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
