DETAILED DESCRIPTION
[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] This embodiment provides a pathology section marking device, which is mainly used to improve the marking efficiency of pathology sections under a microscope.
[0028] like Figure 1 As shown, it includes an ink cartridge 1 for being fixedly mounted on a microscope, the ink cartridge 1 is provided with a marking needle 4 for dipping ink and a driving component 5 for sending the marking needle 4 to a slicing position below the microscope.
[0029] Through the above arrangement, the ink cartridge 1 is fixed on the microscope, eliminating the operator's need to manually hold the ink cartridge 1 when marking the sample, thereby reducing the operator's burden. The driving component 5 is then used to drive the marking needle 4 toward the sliced tissue, so that the ink on the marking needle 4 comes into contact with the sliced tissue, thereby completing the marking of the sliced tissue.
[0030] Specifically, in this embodiment, Figure 1 As shown, the ink cartridge 1 is mounted on an objective lens 100 of a microscope, wherein a glass slide 101 is placed below the objective lens 100 , and a tissue slice is placed on the glass slide 101 , and the tissue slice is located directly below the objective lens 100 .
[0031] In this embodiment, the marking needle 4 can be switched between the first state and the second state. It is worth noting that Figure 1 In the first state, the marking needle 4 is installed at the bottom of the ink cartridge 1, and the sliced tissue is in a non-marking state. Figure 2 In the second state, the marking needle 4 moves to the top of the glass slide 101 and contacts the slice tissue to mark the slice tissue.
[0032] In order to realize that the ink cartridge 1 is mounted on the objective lens 100, in this embodiment, as shown in FIG. Figure 1 and Figure 3 As shown, the side wall of the ink cartridge 1 is provided with a hook and buckle 2 that opens toward the side, wherein the cross section of the hook and buckle 2 is C-shaped. When installing the ink cartridge 1, the hook and buckle 2 can be buckled onto the peripheral wall of the objective lens 100, thereby achieving the installation of the ink cartridge 1.
[0033] When the marking needle 4 moves from the first state to the second state, it is necessary to use the driving component 5 to apply a force to the marking needle 4. This force can move the marking needle 4 downward and sideways at the same time, so that the marking needle 4 contacts the sliced tissue.
[0034] It is worth noting that when the vertical component of the force causes the marking needle 4 to move downward, the ink cartridge 1 is at risk of sliding down along the objective lens 100. Therefore, in this embodiment, Figure 3 and Figure 4 As shown, the side wall of the holding and snap buckle 2 is provided with double-sided tape 21. When the holding and snap buckle 2 is buckled on the objective lens 100, the holding and snap buckle 2 and the objective lens 100 are fixed by the double-sided tape 21, thereby solving the risk of the ink cartridge 1 moving downward.
[0035] In order to improve the stability of the ink cartridge 1 , in this embodiment, two groups of double-sided tapes 21 are provided, thereby improving the firmness of the installation of the ink cartridge 1 .
[0036] During the process of marking the slice tissue, the marking needle 4 needs to move downward and sideways at the same time, so that the marking needle 4 can move to the slice tissue directly below the objective lens 100. Therefore, the moving path of the marking needle 4 needs to be planned so that the marking needle 4 can accurately contact the slice tissue to achieve marking of the slice tissue.
[0037] Therefore, in this embodiment, if Figure 1 and Figure 2 As shown, the ink cartridge 1 is provided with a guide member 3 for guiding the movement of the marking needle 4. Specifically, as shown in FIG. Figure 4As shown, the guide component 3 includes a first guide shell 31 and a second guide shell 32, wherein the bottom of the ink cartridge 1 is in an inverted downward cone, the second guide shell 32 is installed on the side wall of the bottom of the ink cartridge, and the first guide shell 31 is installed on the side wall of the ink cartridge 1 and is arranged vertically downward. The first guide shell 31 and the second guide shell 32 are connected, wherein the inclined axis of the second guide shell 32 points to the sliced tissue, and the driving component 5 is installed in the guide component 3.
[0038] Specifically, such as Figure 5 and Figure 6 As shown, the driving component 5 includes a pressing needle 51, wherein a guide hole 321 is provided in the second guide shell 32, and the pressing needle 51 is arranged in the inner cavity of the first guide shell 31, and then passes through the guide hole 321 and is fixedly connected to the marking needle 4.
[0039] Through the above-mentioned setting, when the pressing needle 51 inside the first guide shell 31 moves downward, the pressing needle 51 begins to bend at the connection position between the guide hole 321 and the inner cavity of the first guide shell 31, and the pressing needle 51 is in an inclined state. At this time, the pressing needle 51 can push the marking needle 4 toward the slice tissue, which facilitates the control of the moving route of the marking needle 4 and enables the marking needle 4 to accurately reach the slice tissue.
[0040] In order to facilitate the pressing of the pressing needle 51, in this embodiment, as shown in FIG. Figure 6 and Figure 7 As shown, the side wall of the first guide shell 31 is also provided with a guide groove 311, and the driving component 5 also includes a pressing plate 52 and a spring 53. The pressing plate 52 is partially installed in the inner cavity of the first guide shell 31 and can slide up and down along the inner wall of the first guide shell 31. The other part of the pressing plate 52 extends to the outside of the first guide shell 31 through the guide groove 311. The pressing plate 52 can be manually moved to realize the up and down movement of the pressing plate 52. The spring 53 is sleeved on the outside of the pressing needle 51, and one end of the spring 53 abuts against the bottom wall of the pressing plate 52. The other end of the spring 53 is fixedly connected to the bottom wall of the inner cavity of the first guide shell 31, and the pressing needle 51 is fixedly connected to the pressing plate 52.
[0041] Through the above arrangement, the pressing plate 52 is pushed downward by hand. Figure 1 Move to the position in Figure 2 The pressing plate 52 is in the middle position, at this time the pressing needle 51 moves toward the inside of the guide hole 321 and extends outward, thereby pushing the marking needle 4 to move toward the slice tissue to mark the slice tissue; when the slice tissue marking is completed, the restriction on the pressing plate 52 is released, and the pressing plate 52 is reset under the elastic force of the spring 53, thereby driving the marking needle 4 to switch from the second state to the first state, thereby realizing the return of the marking needle 4. After the marking needle 4 is returned to its position, it can avoid the marking needle 4 affecting the observation line of the slice tissue.
[0042] In order to be able to transfer the ink in the ink cartridge 1 to the marking needle 4, in this embodiment, as shown in FIG. Figure 5 and Figure 7 As shown, the marking needle 4 includes a base 41, a needle core 42 and a marking sponge 43, wherein the base 41 is fixedly connected to the pressing needle 51, the needle core 42 is installed on the base 41, the marking sponge 43 is installed at the bottom of the base 41, the lower part of the needle core 42 is inserted into the marking sponge 43, and the bottom of the ink cartridge 1 is provided with an ink bottle opening 10, wherein the upper part of the needle core 42 is inserted into the ink bottle opening 10.
[0043] Through the above arrangement, the needle core 42 is inserted into the ink bottle mouth 10 and the ink bottle mouth 10 is sealed, the needle core 42 is used to absorb the ink in the ink cartridge 1, and then the ink is transferred to the marking sponge 43. When marking the sliced tissue, the marking sponge 43 can be directly touched to the sliced tissue.
[0044] Specifically, in this embodiment, Figure 5 As shown, the upper portion of the needle core 42 is in a pointed cone shape, and the shape of the ink bottle mouth 10 is adapted to the shape of the top of the needle core 42 .
[0045] It is worth noting that the ink bottle mouth 10 can adopt a conical surface, wherein the upper end is small and the lower end is large.
[0046] With the above arrangement, when the pressing needle 51 is pressed downward, the conical surface at the top of the needle core 42 and the conical surface of the ink bottle mouth 10 slide relative to each other, thereby facilitating the movement of the marking needle 4 obliquely downward.
[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
