Abstract
Description
Technical Field
[0001] This utility model relates to the field of slicing device technology, and in particular to a tumor sample slicing device. Background Technology
[0002] A tumor is a new growth formed by the proliferation of local tissue cells under the influence of various carcinogenic factors. Tumors arise when the body is subjected to the long-term combined effects of multiple factors, including chemical, viral, and physical factors in the environment, or changes in the body's own genetic and endocrine systems, leading to gene abnormalities. Tumor biopsy is a commonly used method in pathology. It involves cutting and staining tissue samples to observe changes in the morphology and structure of cells and tissues to determine the nature of the lesion and make a pathological diagnosis; it is also known as a biopsy.
[0003] In current tumor sample slicing procedures, doctors need to use tools to compress the tumor sample before slicing it with a scalpel. However, when compressing or slicing the tumor sample, the sample deforms under pressure, increasing the difficulty of compression and slicing. Furthermore, it is difficult to achieve the required precision when slicing the sample with a scalpel after compression. Utility Model Content
[0004] (I) Purpose of the utility model
[0005] In view of this, the purpose of this utility model is to propose a tumor sample slicing device. The technical problem to be solved is that in the existing tumor sample slicing process, doctors need to use tools to compress the tumor sample and then use a scalpel to slice the sample. However, when compressing or slicing the tumor sample, the tumor sample will deform accordingly with the pressure, which increases the difficulty of compression and slicing. Moreover, when slicing with a scalpel after compression, it is also impossible to effectively control the required precision.
[0006] (II) Technical Solution
[0007] To achieve the above-mentioned technical objectives, this utility model provides a tumor sample slicing device:
[0008] It includes a base plate, two vertical plates fixed to the top of the base plate, two clamping plates between the two vertical plates, a first connecting plate fixed to the middle of the top of the clamping plates, a threaded sleeve fixed to the top of the first connecting plate, a bidirectional screw rotatably connected to the top of the two vertical plates, a handle fixed to one end of the bidirectional screw extending outside the vertical plates, the bidirectional screw passing through the threaded sleeve and threadedly connected to the threaded sleeve, a storage plate between the two clamping plates, a blade inside the storage plate, and a control component for controlling the blade to slice tumor samples on the storage plate.
[0009] Preferably, the two threaded sections on the bidirectional screw have opposite directions, and the two threaded sleeves are located on different threaded sections.
[0010] Preferably, two guide rods are fixed between the two vertical plates, two second connecting plates are fixed to the top of the clamping plate, a first limiting sleeve is fixed to the top of the second connecting plate, the guide rod passes through the first limiting sleeve, the first limiting sleeve slides on the guide rod, and scale lines are provided on the guide rod.
[0011] Preferably, the control component includes two connecting rods that pass through the storage plate and slide within the storage plate. The storage plate has an inner cavity for the blade to slide in, and the end of the connecting rod extending into the inner cavity is fixed to the blade.
[0012] Preferably, a pressure rod is fixed to the top of both connecting rods, and a spring is sleeved on the outside of the connecting rod, with one end of the spring abutting against the pressure rod and the other end of the spring abutting against the storage plate.
[0013] Preferably, two third connecting plates are fixed to the top of the storage plate, and a third limiting sleeve is fixed to the top of the third connecting plate. The guide rod passes through the third limiting sleeve, and the third limiting sleeve is slidably fitted on the guide rod.
[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:
[0015] 1. Place the tumor sample on the bottom plate, then rotate the handle to make the bidirectional screw rotate. When the bidirectional screw rotates, it causes the two threaded sleeves to move closer to each other. When the threaded sleeves move, they cause the first connecting plate and clamping plate to move. When the two clamping plates move closer to each other, they clamp the tumor sample. Then press down the pressing rod to make the connecting rod and blade move down. When the blade moves down, it slices the clamped and fixed tumor sample. This method can slice the tumor sample more easily.
[0016] 2: When it is necessary to slice a certain location of a tumor sample, the storage plate is moved to move the blade. When the storage plate moves, it also moves the third connecting plate and the third limiting sleeve. By observing the scale line, the position of the blade relative to the tumor sample can be determined, such as one-third, one-quarter, or one-fifth, thereby improving the accuracy of the slicing position.

[0022] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.
[0023] Reference Figs. 1-3 :
[0024] In one embodiment of this utility model, a tumor sample slicing device is provided, including a base plate 1, two vertical plates 2 fixed to the top of the base plate 1, two clamping plates 3 disposed between the two vertical plates 2, a first connecting plate 4 fixed to the middle position of the top of the clamping plates 3, a threaded sleeve 5 fixed to the top of the first connecting plate 4, a bidirectional screw 6 rotatably connected to the top of the two vertical plates 2, a handle 7 fixed to one end of the bidirectional screw 6 extending outside the vertical plates 2, the bidirectional screw 6 passing through the threaded sleeve 5 and threadedly connected to the threaded sleeve 5, a receiving plate 8 disposed between the two clamping plates 3, a blade 9 disposed inside the receiving plate 8, and a control component for controlling the blade 9 to slice the tumor sample on the receiving plate 8.
[0025] Among them, the two threaded sections of the bidirectional screw 6 are in opposite directions, and the two threaded sleeves 5 are located on different threaded sections. Two guide rods 10 are fixed between the two vertical plates 2. Two second connecting plates 12 are fixed at the top of the clamping plate 3. A first limiting sleeve 13 is fixed at the top of the second connecting plate 12. The guide rod 10 passes through the first limiting sleeve 13. The first limiting sleeve 13 slides on the guide rod 10. A scale line 11 is provided on the guide rod 10.
[0026] It should be noted that when it is necessary to slice a certain location of a tumor sample, the storage plate 8 is moved to move the blade 9. When the storage plate 8 moves, it also moves the third connecting plate 14 and the third limiting sleeve 15. By observing the scale line 11, the position of the blade 9 relative to the tumor sample can be determined, such as one-third, one-quarter, or one-fifth, thereby improving the accuracy of the slicing position.
[0027] Furthermore, the control assembly includes two connecting rods 17, which pass through the storage plate 8 and slide within it. The storage plate 8 has an inner cavity 16 for the blade 9 to slide in. The end of the connecting rod 17 extending into the inner cavity 16 is fixed to the blade 9. A pressure rod 19 is fixed to the top of the two connecting rods 17. A spring 18 is sleeved on the outside of the connecting rod 17, with one end of the spring 18 abutting against the pressure rod 19 and the other end of the spring 18 abutting against the storage plate 8. Two third connecting plates 14 are fixed to the top of the storage plate 8, and a third limiting sleeve 15 is fixed to the top of the third connecting plate 14. A guide rod 10 passes through the third limiting sleeve 15, and the third limiting sleeve 15 is slidably fitted onto the guide rod 10.
[0028] When it is necessary to slice a tumor sample, first place the tumor sample on the base plate 1, then rotate the handle 7 to drive the bidirectional screw 6 to rotate. When the bidirectional screw 6 rotates, it drives the two threaded sleeves 5 to move closer to each other. When the threaded sleeves 5 move, they drive the first connecting plate 4 and the clamping plate 3 to move. When the two clamping plates 3 move closer to each other, they clamp the tumor sample. Then, press down the pressure rod 19 to drive the connecting rod 17 and the blade 9 to move down. When the blade 9 moves down, it slices the clamped and fixed tumor sample. After slicing, release the pressure rod 19. At this time, the blade 9 moves up under the rebound force of the spring 18. Then, rotate the handle 7 in the opposite direction to drive the bidirectional screw 6 to rotate in the opposite direction, so that the two clamping plates 3 move away from each other, so that the clamping plates 3 release the sliced tumor sample, and the sliced tumor sample can be taken out.
[0029] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
