Description

Technical Field

[0001] The present invention relates to the technical field of clinical pathology department equipment, and particularly to a device for fixing and transporting pathological specimens. Background Art

[0002] There is a wide variety of equipment in the clinical pathology department, each with different functions. Biopsy forceps and puncture needles are used for specimen collection to accurately obtain tissue samples. Specimen fixation often relies on formalin fixative containers and automatic tissue fixators to ensure the stability of tissue morphology. Tissue dehydrators and paraffin embedding machines process specimens in preparation for sectioning. Rotary microtomes and cryostat microtomes are responsible for cutting specimens into thin slices. Automatic staining machines and special staining equipment make cell structures clearly presented. Finally, optical microscopes are used by doctors to observe the sections for disease diagnosis. These devices work closely together and play a crucial role in disease diagnosis and treatment plan formulation. They are indispensable tools in the clinical pathology department. In the clinical pathology diagnosis workflow, the fixation and transportation of pathological specimens are two key links.

Detailed implementation manners

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1-8 , the present invention provides a technical solution: a device for fixing and transporting pathological specimens, including a bottom plate 1, a side plate 2 is fixedly connected to the upper surface of the bottom plate 1, a handling handle 3 is fixedly connected to one side surface of the side plate 2, a lifting mechanism 4 is arranged on the upper surface of the bottom plate 1, and a sealing and fixing mechanism 5 is arranged on the lower surface of the lifting mechanism 4; The lifting mechanism 4 includes a fixing plate 401, a motor 402, a lead screw 403, a lifting block 404, a limiting block 405, a limiting groove 406, a connecting plate 407, a first limiting rod groove 408, a limiting rod 409, a top plate 410 and a second limiting rod groove 411. The upper surface of the bottom plate 1 is fixedly connected with the fixing plate 401. One side surface of the fixing plate 401 is fixedly connected with the motor 402. One end surface of the motor 402 is fixedly connected with the lead screw 403. The outer surface of the lead screw 403 is threadedly connected with the lifting block 404. One side surface of the lifting block 404 is fixedly connected with the limiting block 405. One side surface of the fixing plate 401 is provided with the limiting groove 406. One side surface of the lifting block 404 is fixedly connected with the connecting plate 407. The inner surface of the connecting plate 407 is provided with the first limiting rod groove 408. The inner surface of the first limiting rod groove 408 is slidably connected with the limiting rod 409. The upper surface of the fixing plate 401 is fixedly connected with the top plate 410. The inner surface of the top plate 410 is provided with the second limiting rod groove 411. Through the arrangement of the fixing plate 401, the motor 402, the lead screw 403, the lifting block 404, the limiting block 405, the limiting groove 406, the connecting plate 407, the first limiting rod groove 408, the limiting rod 409, the top plate 410 and the second limiting rod groove 411, when in use, start the motor 402, and the lead screw 403 connected to one end of the motor 402 starts to rotate. Since the lead screw 403 is threadedly connected with the lifting block 404, according to the principle of screw drive, the rotational motion of the lead screw 403 will be converted into the linear motion of the lifting block 404. When the lifting block 404 performs linear motion, the limiting block 405 on one side of the lifting block 404 slides inside the limiting groove 406 on the fixing plate 401. When the lead screw 403 drives the lifting block 404 to lift or lower, the connecting plate 407 slides along the limiting rod 409. By the forward and reverse rotation of the motor 402, the lead screw 403 can be driven to rotate forward or backward, so as to make the lifting block 404 realize the action of rising or falling. When the motor 402 rotates forward, the lead screw 403 drives the lifting block 404 to lower. When the motor 402 rotates in reverse, the lead screw 403 drives the lifting block 404 to rise. In the pathological specimen fixing and transporting device, the specimen can be placed in the specimen placement frame 509, and through the lifting action of the lifting block 404, the lifting operation of the specimen can be realized, which provides convenience for operations such as immersing the specimen in the fixing solution or taking it out.

[0020] Furthermore, there are two groups of side plates 2 and handling handles 3 symmetrically arranged with respect to the central axis of the bottom plate 1. The side surface of the handling handle 3 is provided with anti-slip patterns. Through the arrangement of the handling handle 3, when in use, setting two groups of handling handles 3 facilitates the operator to grip the device at different positions and is easier to carry. When the device needs to be moved, the operator can hold the handling handles 3 on both sides with both hands to achieve stable operation. The anti-slip patterns provided on the side surface of the handling handle 3 increase the friction between the human hand and the handle, prevent the device from slipping out of the hand during transportation, reduce the risk of the device falling, and make the specimen handling safer.

[0021] Further, the limiting block 405 is slidably connected to the limiting groove 406. A plurality of groups of limiting blocks 405 are arranged at equal intervals on one side surface of the lifting block 404. Through the arrangement of the limiting block 405 and the limiting groove 406, during use, when the lead screw 403 rotates to drive the lifting block 404 to move up and down, the plurality of groups of limiting blocks 405 slide in the limiting groove 406, sharing various forces received by the lifting block 404 during the movement process, including its own gravity, the weight of the connecting components, and possible inertial forces, etc., avoiding wear or deformation caused by excessive local stress, and making the movement of the lifting block 404 smoother and more stable.

[0022] Further, two groups of limiting rods 409 are arranged on the upper surface of the bottom plate 1. One end of the limiting rod 409 is fixedly connected to the bottom plate 1. Through the arrangement of the limiting rods 409, during use, the two groups of limiting rods 409 can more evenly share the forces generated when the lifting block 404 moves, enhancing the structural stability of the entire device. The two groups of limiting rods 409 work together to provide a relatively closed and stable space environment for the up and down movement of the lifting block 404, enabling the lifting block 404 to move up and down along the designed vertical path, ensuring the reliability and accuracy of the lifting action.

[0023] Further, the sealing and fixing mechanism 5 includes a liquid storage tank 501, a first sealing valve 502, an infusion connecting pipe 503, a control valve 504, a liquid output pipe 505, an annular pipe 506, a liquid outlet pipe 507, a connecting rod 508, a specimen placement frame 509, a sealing block 510, a sealing groove 511, a sealing ring 512, a fixing tank 513, a second sealing valve 514, a liquid discharge connecting pipe 515 and a placement groove 516. The lower surface of the connecting plate 407 is fixedly connected with the liquid storage tank 501. The outer surface of the liquid storage tank 501 is fixedly connected with the first sealing valve 502. One end surface of the first sealing valve 502 is fixedly connected with the infusion connecting pipe 503. The lower surface of the liquid storage tank 501 is fixedly connected with the control valve 504. One end surface of the control valve 504 is fixedly connected with the liquid output pipe 505. One end surface of the liquid output pipe 505 is fixedly connected with the annular pipe 506. The lower surface of the annular pipe 506 is fixedly connected with the liquid outlet pipe 507. The lower surface of the liquid storage tank 501 is fixedly connected with the connecting rod 508. The lower surface of the connecting rod 508 is fixedly connected with the specimen placement frame 509. The lower surface of the liquid storage tank 501 is fixedly connected with the sealing block 510. The lower surface of the sealing block 510 is provided with the sealing groove 511. The inner surface of the sealing groove 511 is slidably connected with the sealing ring 512. The lower surface of the sealing ring 512 is fixedly connected with the fixing tank 513. The outer surface of the fixing tank 513 is fixedly connected with the second sealing valve 514. One end surface of the second sealing valve 514 is fixedly connected with the liquid discharge connecting pipe 515. The upper surface of the bottom plate 1 is provided with the placement groove 516. Through the settings of the liquid storage tank 501, the first sealing valve 502, the infusion connecting pipe 503, the control valve 504, the liquid output pipe 505, the annular pipe 506, the liquid outlet pipe 507, the connecting rod 508, the specimen placement frame 509, the sealing block 510, the sealing groove 511, the sealing ring 512, the fixing tank 513, the second sealing valve 514, the liquid discharge connecting pipe 515 and the placement groove 516, when in use, the liquid storage tank 501 is a container for storing the pathological specimen fixing liquid, and it is installed on the lifting mechanism 4 through the connecting plate 407. When it is necessary to supplement the fixing liquid, the first sealing valve 502 is opened, and the fixing liquid is input into the liquid storage tank 501 through the infusion connecting pipe 503. After the input is completed, the first sealing valve 502 is closed to ensure that the liquid in the liquid storage tank 501 will not leak, ensuring the sealing performance of the liquid storage tank 501. When it is necessary to fix the specimen, the lifting mechanism 4 is started to drive the liquid storage tank 501 to rise, the specimen is placed in the specimen placement frame 509, and then the liquid storage tank 501 is lowered so that the sealing ring 512 is clamped into the sealing groove 511 in the sealing block 510 to form a tight sealing connection. Then the control valve 504 is opened, and the fixing liquid in the liquid storage tank 501 flows into the annular pipe 506 under the action of gravity. The annular pipe 506 evenly distributes the fixing liquid to a plurality of liquid outlet pipes 507, and the fixing liquid exits from the liquid outlet pipes 507. The specimen placement frame 509 is provided with hydrophobic holes, and these hydrophobic holes allow the fixing liquid to pass through.The fixing liquid can contact the specimen to fix the specimen. The second sealing valve 514 and the liquid discharge connecting pipe 515 are used to discharge the fixing liquid. When the specimen fixing is completed and it is necessary to replace the fixing liquid or clean the fixing tank 513, the second sealing valve 514 is opened, and the fixing liquid is discharged through the liquid discharge connecting pipe 515.

[0024] Furthermore, the infusion connecting pipe 503 is fixedly connected to the liquid storage tank 501 through the first sealing valve 502. Two groups of liquid output pipes 505 are arranged on the lower surface of the liquid storage tank 501. Through the arrangement of the liquid output pipes 505, during use, setting multiple groups of liquid output pipes 505 can increase the output channels of the fixing liquid, which helps to improve the efficiency of transporting the fixing liquid from the liquid storage tank 501 to the annular pipe 506. The fixing liquid can flow out from these two groups of liquid output pipes 505 simultaneously, avoiding the problems of uneven distribution or untimely transportation of the fixing liquid caused by insufficient flow rate of a single liquid output pipe 505. Multiple groups of liquid output pipes 505 can share the pressure and impact force generated when transporting the fixing liquid downward from the liquid storage tank 501, making the flow of the fixing liquid more stable, reducing the risk of damage to a single pipe due to excessive force, and making the entire fixing liquid transportation system more reliable.

[0025] Furthermore, multiple groups of liquid outlet pipes 507 are arranged at equal intervals on the lower surface of the annular pipe 506. Multiple groups of connecting rods 508 are arranged on the lower surface of the liquid storage tank 501. Through the arrangement of the liquid outlet pipes 507, during use, the multiple groups of liquid outlet pipes 507 arranged at equal intervals ensure that when the fixing liquid flows out from the annular pipe 506, it can be released simultaneously at multiple positions, forming a uniform spraying or dripping range. The uniform distribution of the fixing liquid can ensure that all parts of the specimen can be fully and uniformly fixed, avoiding poor fixing effects caused by excessive or insufficient fixing liquid in local areas, which may affect subsequent pathological diagnosis. Multiple groups of liquid outlet pipes 507 can cover a wider area, enabling the fixing liquid to evenly contact the surface of the specimen and preventing the situation where the fixing liquid only concentrates in certain areas and some areas of the specimen are not fully fixed.

[0026] Furthermore, multiple groups of hydrophobic holes are arranged at equal intervals on the surface of the specimen placement frame 509. The specimen placement frame 509 is fixedly connected to the liquid storage tank 501 through the connecting rod 508. Through the arrangement of the specimen placement frame 509, during use, when the fixing liquid flows out from the annular pipe 506 through the liquid outlet pipe 507, it will reach the area of the specimen placement frame 509. The fixing liquid can contact the pathological specimen placed in the specimen placement frame 509 through these holes. The hydrophobic holes are arranged at equal intervals, enabling the fixing liquid to act on the specimen evenly after entering the specimen placement frame 509.

[0027] Furthermore, the inner dimension of the sealing groove 511 matches the outer dimension of the sealing ring 512. The fixing tank 513 and the liquid storage tank 501 are arranged in parallel. Through the settings of the sealing groove 511 and the sealing ring 512, during use, the sealing groove 511 and the sealing ring 512 are closely attached to form a stable sealing structure, ensuring the sealing environment inside the fixing tank 513, preventing the fixing liquid from leaking due to poor sealing, guaranteeing the safety of the working environment, and at the same time ensuring that the fixing liquid can fix the specimen in a relatively enclosed space, improving the fixing effect.

[0028] Furthermore, the liquid discharge connecting pipe 515 is fixedly connected to the fixing tank 513 through the second sealing valve 514. The inner dimension of the placement groove 516 matches the outer dimension of the fixing tank 513. Through the settings of the placement groove 516 and the fixing tank 513, during use, when the fixing tank 513 is placed in the placement groove 516, due to the matching of the dimensions, the fixing tank 513 can be firmly fixed on the bottom plate 1 without shaking or displacement, making the fixing tank 513 more stable during the operation of the device.

[0029] Working principle: When it is necessary to move the device, the operator can hold the handling handles 3 on both sides with both hands to achieve stable transfer. Start the motor 402, and the lead screw 403 connected to one end of the motor 402 starts to rotate. Since the lead screw 403 is threadedly connected to the lifting block 404, according to the principle of screw drive, the rotational motion of the lead screw 403 will be converted into the linear motion of the lifting block 404. When the lifting block 404 performs linear motion, the limit block 405 on one side of the lifting block 404 slides inside the limit groove 406 on the fixed plate 401. When the lead screw 403 drives the lifting block 404 to lift or lower, the connecting plate 407 slides along the limit rod 409. By the forward and reverse rotation of the motor 402, the lead screw 403 can be driven to rotate forward or backward, thereby enabling the lifting block 404 to perform the ascending or descending action. When the motor 402 rotates forward, the lead screw 403 drives the lifting block 404 to descend. When the motor 402 rotates in reverse, the lead screw 403 drives the lifting block 404 to ascend. In the pathological specimen fixation and transfer device, the specimen can be placed in the specimen placement frame 509. Through the lifting action of the lifting block 404, the lifting operation of the specimen is realized, which provides convenience for operations such as immersing the specimen in the fixing liquid or taking it out. The liquid storage tank 501 is a container for storing the pathological specimen fixing liquid. It is installed on the lifting mechanism 4 through the connecting plate 407. When it is necessary to replenish the fixing liquid, open the first sealing valve 502, and input the fixing liquid into the liquid storage tank 501 through the infusion connecting pipe 503. After the input is completed, close the first sealing valve 502 to ensure that the liquid in the liquid storage tank 501 will not leak, ensuring the sealing performance of the liquid storage tank 501. When it is necessary to fix the specimen, start the lifting mechanism 4 to drive the liquid storage tank 501 to rise, place the specimen in the specimen placement frame 509, and then lower the liquid storage tank 501 so that the sealing ring 512 is snapped into the sealing groove 511 in the sealing block 510 to form a tight sealing connection. Then open the control valve 504. Under the action of gravity, the fixing liquid in the liquid storage tank 501 flows into the annular pipeline 506 through the liquid output pipe 505. The annular pipeline 506 evenly distributes the fixing liquid to multiple liquid outlet pipes 507. The fixing liquid exits from the liquid outlet pipes 507. The specimen placement frame 509 is provided with hydrophobic holes, and these hydrophobic holes allow the fixing liquid to pass through, enabling the fixing liquid to contact the specimen to achieve the fixation of the specimen. The second sealing valve 514 and the drain connecting pipe 515 are used to drain the fixing liquid. When the specimen fixation is completed and it is necessary to replace the fixing liquid or clean the fixing tank 513, open the second sealing valve 514, and the fixing liquid is discharged through the drain connecting pipe 515. The model of the motor 402 is YE2-132S-4. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
