Description

Technical Field

[0001] This invention relates to the field of tumor pathological specimen fixation and preservation technology, specifically a tumor pathological specimen fixator. Background Technology

[0002] Tumor pathology specimens refer to diseased tissues obtained from a patient through surgical resection, puncture, or endoscopic biopsy. They are primarily used for pathological analysis to determine the nature, type, and grade of the tumor. After being removed from the body, these specimens undergo pretreatment processes such as fixation, dehydration, and embedding to ensure cellular stability and facilitate subsequent observation. Tumor pathology slides are a specific form of tumor pathology specimen. They are thin-layer tissue samples prepared from raw tumor tissue through techniques such as slicing and staining, mounted on glass slides for microscopic observation and diagnosis.

[0003] The aforementioned devices lack the structure for rapid fixation, quick identification and retrieval of tumor pathology slides, and prevention of falling and damage during storage. This means that existing tumor pathology slides are mostly stored in drawer-type slide cabinets, and fixation often relies on foam inserts. Multiple slides are often stacked together, leading to friction and damage between them. Furthermore, the fixation effect is poor, making it difficult to quickly identify and retrieve slides. Additionally, if the tabletop is tilted or subjected to other external forces during the pulling or storage process, the storage drawer is prone to slipping and falling from the cabinet, causing the tumor pathology slides inside to break. Based on the shortcomings of existing technology, this invention designs a tumor pathology slide fixator. Summary of the Invention

[0013] As a preferred embodiment of the present invention, the storage drawer is slidably inserted into the interior of the storage compartment.

[0014] As a preferred embodiment of the present invention, the storage drawer is disposed on top of the fixed box.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This tumor pathology specimen fixator involves taking out a new pick-and-place mechanism from the storage drawer, inserting one end of the prepared tumor pathology slide specimen into the slot, and then filling in the information of the tumor pathology slide specimen in the slot on the specimen label. At this time, the corresponding storage drawer is opened according to the type of tumor pathology slide specimen. Then, the tumor pathology slide specimen is fixed with its head facing down using the pick-and-place mechanism. Then, an empty fixing sleeve is selected in the storage drawer, the tumor pathology slide specimen is aligned with the fixing sleeve, inserted into the sleeve, and then squeezed and fixed using a buffer strip. This device facilitates contactless and rapid fixation of tumor pathology slide specimens.

[0016] 2. This tumor pathology specimen holder allows users to observe the type of label inside the label insert on the storage drawer, grasp the second handle on the corresponding storage drawer to pull it out, and then slowly push the lever head backward to drive the slide and the second magnet to slide backward on the slide rail. During the slow backward movement of the slide and the second magnet, the second magnet will pass under multiple fixing sleeves and the first magnet. Since the first and second magnets are like poles and repel each other, the second magnet will use the first magnet to push the multiple fixing sleeves upward one by one as it moves. After being pushed up, the fixing sleeves will move upward along with the tumor pathology slide specimen, which will drive the picking and placing mechanism to move upward as well. This allows the user to quickly observe the types of tumor pathology slide specimens one by one until the required tumor pathology slide specimen is selected. This device facilitates the quick retrieval of the required tumor pathology slide specimen.

[0017] 3. This tumor pathology specimen fixator allows for the selection of the desired tumor pathology slide specimen based on the specimen label. The user then simultaneously pinches the sliders on both sides of the placement seat with their thumb and forefinger, causing the sliders and clamps to move inwards and push the anti-slip strips to clamp and fix the tumor pathology slide specimen. The placement seat can then be removed upwards. During this upward movement, the tumor pathology slide specimen is pulled out from inside the fixing sleeve. After extraction, the placement seat is flipped so that the tumor pathology slide specimen faces upwards. The four support arms are then rotated to fully extend the slide. Finally, the placement seat and the tumor pathology slide specimen are placed on a table and supported by the support arms. This device facilitates the non-contact removal of tumor pathology slide specimens and their placement on a table for use.

[0018] 4. This tumor pathology specimen holder, when the storage drawer is fully inserted into the storage chamber, has a one-way limiting groove at the bottom of the drawer engaged with a one-way locking tongue, locking the drawer and preventing it from being pulled out. When a tumor pathology slide specimen needs to be retrieved, the pull rod is pulled down, causing the side lever to move the one-way locking tongue downwards under the limiting position of the movable groove, allowing the side lever to be pulled out from inside the one-way limiting groove and release the lock on the drawer. At this point, the drawer can be pulled out to find the required tumor pathology slide specimen. After the drawer is pulled out, the pull rod is released, and the first spring can quickly push the one-way locking tongue upwards to reset and insert into the corresponding one-way limiting groove to continuously lock the drawer, preventing the drawer from slipping and falling due to the tilt of the table when it is pulled out, thus preventing damage to the internal tumor pathology slide specimen.

The support arm 405 is rotatably connected to the rotating shaft 404. The slot 406 is opened at the bottom of the pick-and-place seat 401. A side passage 407 is formed through both sides of the pick-and-place seat 401. A baffle 408 is fixedly connected inside the side passage 407. A slider 409 is slidably connected inside the side passage 407. A clamping plate 410 is fixedly connected to the inner end of the slider 409. A hollow groove 411 is formed through the slider 409 and the clamping plate 410. A second spring 412 is disposed between the inner wall of the hollow groove 411 and the baffle 408. An anti-slip strip 413 is fixedly connected to the inner side of the clamping plate 410. A support arm 405 is rotatably disposed inside the storage groove 403. A baffle 408 is disposed inside the hollow groove 411. The anti-slip strip 413 is clamped and disposed on both sides of the tumor pathology slide specimen 507.

[0027] By setting up a pick-and-place seat 401, a side passage groove 407, a clamping plate 410, and an anti-slip strip 413, it is possible to connect with the top of the tumor pathology slide specimen 507 and remove the tumor pathology slide specimen 507 from the fixing sleeve 505 without contact. By setting up a storage groove 403, a rotating shaft 404, and a support arm 405, it is possible to place the pick-and-place seat 401 upside down on the table with the tumor pathology slide specimen 507 facing upwards for use. By setting up a baffle 408, an empty groove 411, and a second spring 412, it is possible to push the anti-slip strip 413, the clamping plate 410, and the slider 409 outward a certain distance when the pick-and-place seat 401 does not need to pick up the tumor pathology slide specimen 507, thereby releasing the clamping and fixing of the tumor pathology slide specimen 507 by the anti-slip strip 413.

[0028] Please see Figure 4-5 The locking mechanism 3 includes a movable groove 301, a side groove 302, a one-way locking tongue 303, a first spring 304, a side deflector plate 305, a limiting plate 306, a pull rod 307, and a one-way limiting groove 308. The movable groove 301 is formed inside the fixed box 1, and the side groove 302 is formed on the side wall of the fixed box 1, and the side groove 302 communicates with the inner cavity of the movable groove 301. The one-way locking tongue 303 is slidably inserted into the interior of the movable groove 301. The first spring... 304 is fixedly connected to the bottom of the one-way latch 303, the side deflector 305 is fixedly connected to the side wall of the one-way latch 303, the limiting plate 306 is fixedly connected to the outer end of the side deflector 305, the pull rod 307 is fixedly connected to the outer side of the limiting plate 306, the one-way limiting groove 308 is opened at the bottom of the storage drawer 2, the top of the movable groove 301 communicates with the inner cavity of the storage compartment 201, and the one-way latch 303 is slidably engaged in the interior of the one-way limiting groove 308.

[0029] By setting up the movable groove 301, one-way locking tongue 303, first spring 304 and one-way limiting groove 308, the position of the storage drawer 2 can be locked to prevent the storage drawer 2 from sliding out of the storage compartment 201 and falling under the action of other external forces, which would damage the internal tumor pathology slide specimen 507. By setting up the side groove 302, side deflector 305, limiting plate 306 and pull rod 307, the one-way locking tongue 303 can be controlled to move down to lock the storage drawer 2, so that the storage drawer 2 can be pulled out normally to retrieve the tumor pathology slide specimen 507.

[0030] Compared with the prior art, the present invention has the following beneficial effects: 1. This tumor pathology specimen fixation device involves taking out a new pick-and-place mechanism 4 from the storage drawer 104, inserting one end of the prepared tumor pathology slide specimen 507 into the slot 406, and then filling in the information of the tumor pathology slide specimen 507 in the slot 406 on the specimen label 402. At this time, the corresponding storage drawer 2 is opened according to the type of tumor pathology slide specimen 507. Then, the pick-and-place mechanism 4 is used to fix the tumor pathology slide specimen 507 with its head facing down. Then, the empty fixing sleeve 505 in the storage drawer 2 is selected, and the tumor pathology slide specimen 507 is aligned with the fixing sleeve 505 and inserted into it. The buffer strip 506 is used to squeeze and fix it. This device facilitates the non-contact and rapid fixation of the tumor pathology slide specimen 507.

[0031] 2. This tumor pathology specimen fixator, by observing the target label inside the label insert 202 on the storage drawer 2, and grasping the second handle 203 on the corresponding storage drawer 2 to pull out the storage drawer 2, at this time, the lever head 514 is slowly pushed backward by hand, which drives the slide 511 and the second magnet 512 to slide backward on the slide rail 509 via the lever arm 513. During the slow backward movement of the slide 511 and the second magnet 512, the second magnet 512 will pass under multiple fixing sleeves 505 and the first magnet 508. The first magnet 508 and the second magnet 512 repel each other due to their like poles. When the second magnet 512 moves, it uses the first magnet 508 to lift the multiple fixed sleeves 505 one by one. After being lifted, the fixed sleeves 505 use the rod to move the tumor pathology slide specimen 507, which in turn drives the picking and placing mechanism 4 to move upward. This allows the user to quickly observe the types of tumor pathology slide specimens 507 one by one until the desired tumor pathology slide specimen 507 is selected. This device facilitates the quick retrieval of the required tumor pathology slide specimen 507.

[0032] 3. This tumor pathology specimen fixation device, after selecting the desired tumor pathology slide specimen 507 according to the specimen label 402, uses the thumb and forefinger to simultaneously pinch the sliders 409 on both sides of the placement seat 401, causing the sliders 409 and clamps 410 on both sides to move inward simultaneously and push the anti-slip strips 413 to clamp and fix the tumor pathology slide specimen 507 on both sides. At this time, the placement seat 401 can be lifted upward. During the upward movement of the placement seat 401, the tumor pathology slide specimen 507 will be clamped and moved upward, and then pulled out from the inside of the fixing sleeve 505. After being pulled out, the placement seat 401 is flipped so that the tumor pathology slide specimen 507 faces upward. Then, the four support arms 405 are rotated and moved to fully unfold it. Finally, the placement seat 401 and the tumor pathology slide specimen 507 are placed on the table and supported by the support arms 405. This device facilitates the non-contact removal of the tumor pathology slide specimen 507 and its placement on the table for use.

[0033] 4. In this tumor pathology specimen fixation device, when the storage drawer 2 is fully inserted into the storage chamber 201, the one-way limiting groove 308 at the bottom of the storage drawer 2 is engaged with the one-way locking tongue 303, locking the storage drawer 2 so that it cannot be pulled out. When it is necessary to retrieve the tumor pathology slide specimen 507, the pull rod 307 needs to be pulled down, which drives the one-way locking tongue 303 to move downward under the limitation of the movable groove 301 via the side deflector 305, causing the side deflector 305 to move downward from the side. The internal locking of the storage drawer 2 is released when the one-way limiting groove 308 is pulled out. At this time, the storage drawer 2 can be pulled out to find the required tumor pathology slide specimen 507. After the storage drawer 2 is pulled out, the pull rod 307 is released, and the first spring 304 can quickly push the one-way locking tongue 303 to move upward and reset, inserting into the corresponding one-way limiting groove 308 to continuously lock the storage drawer 2, preventing the storage drawer 2 from slipping off and falling due to the tilt of the table when it is pulled out, thus damaging the internal tumor pathology slide specimen 507.

The second magnet 512 slides below the first magnet 508, so that the fixing sleeve 505 and the picking and placing mechanism 4 can be lifted using the first magnet 508 and the second magnet 512 for observation and retrieval. A picking and placing seat 40 is inserted into the top of the tumor pathology slide specimen 507. 1. Side passage grooves 407 are provided on both sides. The clamping plate 410 and anti-slip strip 413 connected to the inner side of the side passage groove 407 are fixed and clamped on both sides of the tumor pathology slide specimen 507, so that the tumor pathology slide specimen 507 can be taken out from the fixed sleeve 505 for use using the pick-and-place seat 401. The support arm 405 provided at the top of the pick-and-place seat 401 can be rotated and unfolded by the pivot 404, so that the pick-and-place seat 401 can be placed upside down on the table so that the tumor pathology slide specimen 507 in the pick-and-place seat 401 is placed facing upward. When it is necessary to quickly fix the tumor pathology slide specimen 507 and locate the required tumor pathology slide specimen 507, first take out the new pick-and-place mechanism 4 from the storage drawer 104, insert one end of the prepared tumor pathology slide specimen 507 into the slot 406, and then fill in the information of the tumor pathology slide specimen 507 in the slot 406 on the specimen label 402. At this time, pull open the corresponding storage drawer 2 according to the type of tumor pathology slide specimen 507, and then use the pick-and-place mechanism 4 to fix the tumor pathology slide specimen 507 with its head facing down. Then select the empty fixing sleeve 505 in the storage drawer 2, align the tumor pathology slide specimen 507 with the fixing sleeve 505, insert it into the interior, and use the cushioning strip 506 to squeeze and fix it. If it is necessary to locate the required tumor pathology slide specimen 507, simply observe the category label in the label insert 202 on the storage drawer 2, and grasp the second handle 20 on the corresponding storage drawer 2. 3. Pull out the storage drawer 2. At this time, slowly push the lever head 514 backward by hand. Through the lever arm 513, the slide 511 and the second magnet 512 will slide backward on the slide rail 509. During the slow backward movement of the slide 511 and the second magnet 512, the second magnet 512 will pass under the multiple fixed sleeves 505 and the first magnet 508. Since the first magnet 508 and the second magnet 512 are like poles and repel each other, the second magnet 512 will use the first magnet 508 to push the multiple fixed sleeves 505 upward one by one when it moves. After being pushed up, the fixed sleeves 505 will use the rod to drive the tumor pathology slide specimen 507 to move the picking and placing mechanism 4 upward as well. This allows the user to quickly observe the types of tumor pathology slide specimens 507 one by one until the required tumor pathology slide specimen 507 is selected. This device facilitates the quick fixation of tumor pathology slide specimens 507 and the search for the required tumor pathology slide specimen 507.

[0035] When it is necessary to remove the tumor pathology slide specimen 507 without contact and place it on the table for use, first select the required tumor pathology slide specimen 507 according to the specimen label 402, then pinch the sliders 409 on both sides of the pick-and-place seat 401 with your thumb and forefinger. This will cause the sliders 409 and the clamping plate 410 to move inward at the same time and push the anti-slip strip 413 to clamp and fix the tumor pathology slide specimen 507 on both sides. At this time, the pick-and-place seat 401 can be lifted upward. During the upward movement of the pick-and-place seat 401, the tumor pathology slide specimen 507 will be clamped and moved upward, and then pulled out from the inside of the fixing sleeve 505. After the extraction is completed, flip the pick-and-place seat 401 so that the tumor pathology slide specimen 507 faces upward. Then rotate and move the four support arms 405 to fully unfold it. Finally, place the pick-and-place seat 401 and the tumor pathology slide specimen 507 on the table and support them with the support arms 405. This device facilitates the removal of the tumor pathology slide specimen 507 without contact and places it on the table for use.

[0036] When it is necessary to prevent the storage drawer 2 from automatically sliding out and falling during carrying or retrieval, firstly, when the storage drawer 2 is fully inserted into the storage compartment 201, the one-way limiting groove 308 at the bottom of the storage drawer 2 is engaged with the one-way locking tongue 303, locking the storage drawer 2 so that it cannot be pulled out. When it is necessary to retrieve the tumor pathology slide specimen 507, the pull rod 307 needs to be pulled down, which drives the one-way locking tongue 303 to move downward under the limitation of the movable groove 301 via the side deflector 305, so that... The side lever 305 is pulled out from inside the one-way limiting groove 308 to release the lock on the storage drawer 2. At this time, the storage drawer 2 can be pulled out to find the required tumor pathology slide specimen 507. After the storage drawer 2 is pulled out, the lever 307 is released, and the first spring 304 can quickly push the one-way locking tongue 303 to move upward and reset to insert into the corresponding one-way limiting groove 308 to continuously lock the storage drawer 2, preventing the storage drawer 2 from slipping and falling due to the tilt of the table when it is pulled out, thus damaging the internal tumor pathology slide specimen 507.
