Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and in particular to a pathology blade holder. Background Technology
[0002] Pathological slides are a type of pathological specimen. When preparing pathological slides, some diseased tissues or organs are first treated with various chemicals and embedding methods to fix and harden them. Then, they are cut into thin slices on a microtome, adhered to a glass slide, and stained with various colors for observation under a microscope to make a pathological diagnosis, thus providing assistance for clinical diagnosis and treatment.
[0003] Microtome slices pathological sections using disposable blades. Because the number of blades used is very large, multiple blades are usually packaged and stored together in a blade box for convenience. When a blade is needed, the blade box must be opened first, and then the blades must be taken out one by one and installed into the microtome. This operation is cumbersome and inconvenient for blade use, therefore, it needs improvement. Utility Model Content
[0004] To facilitate the use of blades, this application provides a pathological blade holder.
[0005] The pathology blade holder provided in this application adopts the following technical solution:
[0006] A pathological blade holder includes a blade storage box, a blade pusher, and a blade loading assembly. The blade storage box has a clearance groove along its length on its upper side, and a blade outlet groove communicating with the clearance groove is formed at one end of the storage box. The blade pusher includes a sliding block and a pushing block. The sliding block is slidably connected to the blade storage box, and the pushing block is disposed on the sliding block and movably passes through the clearance groove. The blade loading assembly includes a placement seat and a plurality of first elastic members. The placement seat is movably disposed in the blade storage box, and the plurality of first elastic members are disposed between the placement seat and the blade storage box to drive the placement seat closer to the pushing block.
[0007] By adopting the above technical solution, in practical applications, multiple blades are placed in the placement seat in the blade storage box to achieve the storage of multiple blades. Multiple first elastic elements drive the placement plate to approach the push block, so that the blade at the top abuts against the blade storage box. By sliding the sliding block, the push block moves along the clearance groove to push the blade at the top out of the blade slot. The operation is simple and convenient, thus facilitating the use of the blades.
[0008] Preferably, the blade storage box has limiting grooves on both sides along its length direction, and the blade pusher also includes two limiting blocks, which are located on both sides of the sliding block and are respectively slidably limited in the two limiting grooves.
[0009] By adopting the above technical solution and setting a limiting groove, the stability of the sliding block's movement can be improved, and the sliding block can be prevented from detaching from the knife storage box, thereby improving the stability of the pathology blade box in use.

[0012] Preferably, the upper blade assembly further includes a limiting frame and a plurality of second elastic members. The upper side of the placement seat is provided with an installation groove. The limiting frame is slidably connected to the installation groove. The plurality of second elastic members are disposed between the limiting frame and the bottom wall of the installation groove to drive the limiting frame to extend out of the installation groove.
[0013] By adopting the above technical solution, and by setting a limiting frame and multiple second elastic elements, the blade is placed on the placement seat and limited within the limiting frame, thereby improving the stability of blade placement and ensuring that the position of the uppermost blade corresponds to the blade ejection groove, thus improving the stability of blade ejection.
[0014] Preferably, the inner side of the limiting frame is provided with a first chamfer.
[0015] By adopting the above technical solution, a first chamfer is set so that the blade is confined within the limiting frame.
[0016] Preferably, the outer side of the limiting frame is provided with a second chamfer.
[0017] By adopting the above technical solution, and by setting a second chamfer, the push block abuts against the second chamfer during the sliding process in the clearance groove, so that the limiting frame extends into the mounting groove, allowing the push block to push the uppermost blade.
[0018] Preferably, the upper blade assembly further includes a plurality of guide posts, which are disposed on the lower side of the limiting frame and movably pass through the placement seat and the blade storage box.
[0019] By adopting the above technical solution and setting multiple guide posts, the stability of the limit frame sliding can be improved.

[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. In practical applications, multiple blades are placed in the placement seat in the blade storage box to store multiple blades. Multiple first elastic elements drive the placement plate to approach the push block, so that the topmost blade abuts against the blade storage box. By sliding the sliding block, the push block moves along the clearance groove to push the topmost blade out from the blade outlet groove. The operation is simple and convenient, thus facilitating the use of the blades.
[0028] 2. By setting a limiting frame and multiple second elastic elements, the blade is placed on the placement seat and limited within the limiting frame, thereby improving the stability of blade placement and ensuring that the position of the uppermost blade corresponds to the blade ejection groove, thus improving the stability of blade ejection.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0038] This application discloses a pathology blade box.
[0039] Reference Figure 1 and Figure 2 The pathology blade holder includes a blade storage box 1, a blade pusher 2, and a blade loading assembly 3. The blade storage box 1 includes a box body 11 and a base 12. The box body 11 is rectangular in shape, with a rectangular clearance groove 111 on its upper side along its length, and a blade dispensing groove 112 at one end of the box body 11, which is connected to the clearance groove 111. The box body 11 has an opening at its lower side, and both ends of the base 12 are engaged with the lower side of the box body 11 to achieve a detachable connection between the base 12 and the box body 11, facilitating the placement of the blades.
[0040] The pusher component 2 includes a sliding block 21 and a pusher block 22. The sliding block 21 is slidably connected to the housing 11, and the sliding direction is the length direction of the housing 11. The pusher block 22 is integrally connected to the sliding block 21. The pusher block 22 is movably inserted through the relief groove 111, that is, the pusher block 22 is slidably limited to the relief groove 111 and extends into the housing 11. The length of the pusher block 22 extending into the housing 11 is the thickness of the blade.
[0041] Reference Figure 2 and Figure 3 The blade mounting assembly 3 includes a mounting base 31 and multiple first elastic elements 32. The mounting base 31 is movable in the blade storage box 1 and is used to hold the blade. The first elastic elements 32 are springs. Multiple first elastic elements 32 are spaced apart and one end is fixedly connected to the lower side of the mounting base 31, and the other end is fixedly connected to the base 12 to drive the mounting base 31 to move closer to the push block 22, that is, to drive the mounting base 31 to move upward.
[0042] In practical applications, multiple blades are placed on the placement seat 31, and the base 12 is then snapped onto the box 11 so that multiple blades are stored in the blade storage box 1. Multiple first elastic members 32 drive the placement seat 31 to move upward, so that the blade at the top abuts against the inside of the box 11. At this time, by sliding the sliding block 21, the push block 22 slides from one end of the clearance groove 111 to the other end of the clearance groove 111, so that the push block 22 pushes the blade at the top out from the blade outlet groove 112, so that the blade can be used. The operation is simple and convenient, thus facilitating the use of the blade.
[0043] Reference Figure 1 and Figure 2 In some embodiments, the two sides of the box body 11 are provided with limiting grooves 113 along its own length direction. The pusher 2 also includes two limiting blocks 23. The two limiting blocks 23 are integrally connected to the two sides of the sliding block 21, and the two limiting blocks 23 are respectively slidably limited in the two limiting grooves 113, thereby improving the stability of the sliding block 21 and restricting the sliding block 21 from leaving the box body 11, so as to improve the stability of the pathological blade box in use.
[0044] Reference Figure 2 and Figure 3 In some embodiments, the upper blade assembly 3 further includes a limiting frame 33 and multiple second elastic members 34. The limiting frame 33 is U-shaped, with one open end located at the blade outlet groove 112. A mounting groove 311 is provided on the upper side of the placement seat 31, the shape of which matches the shape of the limiting frame 33. The limiting frame 33 is slidably connected to the mounting groove 311. The second elastic members 34 are also springs, with one end fixedly connected to the lower side of the limiting frame 33 and the other end fixedly connected to the bottom wall of the mounting groove 311, driving the limiting frame 33 to extend out of the mounting groove 311, i.e., driving the limiting frame 33 to move upwards. When the blade is stored in the blade storage box 1, the blade is confined within the limiting frame 33 to improve the stability of the blade placement and to limit the blade position, ensuring that the uppermost blade position corresponds to the blade outlet groove 112, thereby ensuring accurate blade ejection and improving blade ejection stability.
[0045] In some embodiments, the inner side of the limiting frame 33 is provided with a first chamfer 331 to facilitate the blade being confined within the limiting frame 33. Simultaneously, the outer side of the limiting frame 33 is provided with a second chamfer 332. When the push block 22 slides in the relief groove 111, the push block 22 abuts against the second chamfer 332, causing the limiting frame 33 to extend into the mounting groove 311. Even if the limiting frame 33 moves downwards, the push block 22 can push the uppermost blade, thereby facilitating the ejection of the blade and thus its use.
[0046] In some embodiments, the upper blade assembly 3 further includes a plurality of guide posts 35, which are fixedly connected at intervals to the lower side of the limiting frame 33. Each guide post 35 is movably inserted through the placement seat 31 and the blade storage box 1 to improve the stability of the sliding of the limiting frame 33, thereby improving the stability of the ejected blade. The number of guide posts 35 corresponds to the number of second elastic members 34, and each second elastic member 34 is sleeved on each guide post 35 to limit the movement of the second elastic member 34, minimizing excessive bending and damage, and thus extending the service life of the second elastic member 34.
[0047] Reference Figure 1 and Figure 4 In some embodiments, the pathology blade box also includes a recycling box 4, which is detachably connected to the lower side of the blade storage box 1. A recycling groove 41 is provided at one end of the lower side of the recycling box 4. Used blades are placed into the recycling box 4 through the recycling groove 41 to facilitate the recycling and storage of the blades. Since the recycling box 4 is detachably connected to the blade storage box 1, it is convenient to take out the blades from the recycling box 4.
[0048] In some embodiments, the recycling box 4 has slots 42 on its two inner sides, and the base 12 is snapped into each slot 42 to achieve a detachable connection between the recycling box 4 and the knife storage box 1. The structure is simple and the operation is convenient.
[0049] In some embodiments, the recycling box 4 has a guide groove 43 at the recycling slot 41 to guide the insertion of the blade, thereby facilitating the insertion of the blade into the recycling box 4.
[0050] The implementation principle of this embodiment is as follows: In practical application, multiple blades are placed on the placement seat 31, and the base 12 is then snapped onto the box 11 so that multiple blades are stored in the blade storage box 1. Multiple first elastic members 32 drive the placement seat 31 to move upward, so that the blade at the top abuts against the inner side of the box 11. At this time, by sliding the sliding block 21, the push block 22 slides from one end of the clearance groove 111 to the other end of the clearance groove 111, so that the push block 22 pushes the blade at the top out from the blade outlet groove 112, so that the blade can be used. The operation is simple and convenient, thus facilitating the use of the blade.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
