[0003] During the existing pathological staining operation, an operator needs to place the section on a glass slide and then drop the dye on the section for staining. Due to the differences in the specifications of the sections, when the overall size of the section is large, the operator needs to hold the glass slide by hand and rotate it so that the dye can be fully smeared on the surface of the section. However, manual operation by hand is prone to accidental dropping of the glass slide due to mistakes, and at the same time, manual operation is rather cumbersome, reducing the staining efficiency.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the attached drawings.

[0026] The embodiment of the present utility model discloses an improved device for a pathological staining module.

[0027] The present utility model provides an improved device for a pathological staining module as shown in Figures 1-3 which includes a support frame 1. A vertical rod 2 is rotatably provided at the lower end of the support frame 1. A ball ring 3 is fixedly provided at the top of the vertical rod 2. A ball screw rod 4 is rotatably provided inside the ball ring 3. A connecting block 5 is fixedly provided at the top of the ball screw rod 4. A syringe 7 is fixedly provided at the top of the connecting block 5 through a fixed frame 6. An air duct 8 is communicated with the top of the syringe 7. A positioning suction cup 9 is communicated with the top of the air duct 8. The piston rod of the syringe 7 passes through the fixed frame 6 and is arranged in the air - suction positioning mechanism;

[0028] A horizontal plate 10 is fixedly sleeved on the outer wall of the connecting block 5. A plurality of springs 11 arranged in a circumferentially symmetric manner are fixedly provided between the horizontal plate 10 and the ball ring 3. A push plate 12 is provided on the side of the support frame 1 through an adjusting mechanism. One end of the push plate 12 close to the syringe 7 is semicircularly arranged, and the push plate 12 is cooperatively arranged with the syringe 7.

[0029] Before pathological staining, place the glass slide with the pathological section on the top of the positioning suction cup 9. Then, use the syringe 7 to suck out the air inside the positioning suction cup 9, so that the positioning suction cup 9 can stably adsorb and fix the glass slide. At this time, under the connection of multiple springs 11, the glass slide can be stably set horizontally. Then, drop the dye onto the glass slide and rotate the glass slide through the vertical rod 2. During this process, the push plate 12 can be moved horizontally, so that the end of the push plate 12 contacts the syringe 7, and the syringe 7 is pushed under the connection of multiple springs 11. At this time, the glass slide can tilt during rotation, so that the dye on the surface of the glass slide can stably spread out, ensuring the pathological staining effect.

[0030] In order to stably adsorb and fix the glass slide on the positioning suction cup 9, as Figures 1-2 shown, the air suction and positioning mechanism includes a driving screw 13. The driving screw 13 is rotatably connected to the top of the connecting block 5, and a slider 14 is sleeved on the rod wall in a threaded manner. The slider 14 is in contact and cooperation with the inside of the fixed frame 6. Both ends of the top of the slider 14 are fixedly connected to the end of the piston rod of the syringe 7 through connecting rods 15. A rotating block 16 is fixedly sleeved at the lower end of the driving screw 13.

[0031] When the glass slide is placed on the top of the positioning suction cup 9, the rotating block 16 can be pushed, so that the driving screw 13 drives the slider 14 to move downward. At this time, the piston rod inside the syringe 7 can be pulled under the pulling of the two connecting rods 15. At this time, the syringe 7 performs the air extraction work and discharges the air inside the positioning suction cup 9 through the air duct 8, so that the positioning suction cup 9 can stably adsorb and fix the glass slide on its top under the negative pressure effect, ensuring the stable spreading of the dye on the surface of the glass slide.

[0032] And in order to adjust the tilt angle of the glass slide according to the specifications of the section on the surface of the glass slide, as Figure 1 shown, the adjusting mechanism includes an adjusting screw 17. The adjusting screw 17 is threaded on the side of the support frame 1, and the end is rotatably connected to the push plate 12. A crank 18 is fixedly arranged at the end of the adjusting screw 17. Two symmetrically arranged guide rods 19 are fixedly arranged at the end of the push plate 12. The guide rods 19 are slidably arranged on the side of the support frame 1.

[0033] When the vertical rod 2 starts to rotate, the crank 18 rotates to drive the adjusting screw 17 to move horizontally, so that the push plate 12 moves horizontally under the support of the guide rods 19 and pushes the syringe 7. When the section specification on the surface of the glass slide is large, the horizontal moving distance of the push plate 12 can be increased, so that the section tilts at a large angle, and at this time the dye can spread in a large range. When the section specification is small, the push plate 12 can be horizontally moved a short distance, improving the operation versatility of the device.

[0034] And in order to drive the glass slide to rotate stably, as Figure 1As shown in the figure, a rotation driving mechanism is provided at the lower end of the vertical rod 2. The rotation driving mechanism includes a motor 20 which is fixedly arranged at the lower end inside the support frame 1, and the output end penetrates through the support frame 1 and is fixedly provided with a first transmission wheel 21. A second transmission wheel 22 is fixedly sleeved at the lower end of the vertical rod 2, and a transmission belt 23 is arranged between the first transmission wheel 21 and the second transmission wheel 22 for transmission.

[0035] After the position of the glass slide is fixed, the motor 20 can be started, so that the motor 20 drives the first transmission wheel 21 to rotate. At this time, under the transmission cooperation of the first transmission wheel 21, the second transmission wheel 22 and the transmission belt 23, the vertical rod 2 can rotate stably to drive the glass slide to rotate. When the glass slide is pushed and tilted, the dye on its surface can be spread stably and evenly.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
