Description

Technical Field

[0001] This utility model relates to the field of condenser lens technology for scanners, specifically a condenser lens for a pathological slide scanner. Background Technology

[0002] Currently, in the study of biological tissues, apart from a small number of weakly absorbent tissues, most tissues are highly transparent. Without staining, it is difficult to observe the fine structures of these tissues using ordinary optical microscopes. The observation and imaging of transparent biological tissues mainly relies on phase-contrast microscopy. For a long time, traditional phase-contrast microscopy, which relies on visual observation, has held an important position in life science research.

[0003] During the use of a pathology slide scanner, different condenser lenses are required to be replaced as needed. Each time the condenser lens is replaced, all the external components are disassembled, which makes it very inconvenient to use. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A condenser lens for a pathological slide scanner includes a condensing mechanism and a mounting mechanism. The condensing mechanism includes a central ring, two outer rings suspended at the top and bottom of the central ring, and a condensing lens fitted between the outer rings and the central ring. The mounting mechanism includes a clamp at the top of the central ring, a threaded rod slidingly passing through the clamp, two nuts screwed to the threaded rod, two rods mounted on one side of the clamp, rod sleeves fitted at the bottom of the rods, and multiple connecting rods connected to the central ring and the outer rings. The multiple connecting rods are respectively fixed to the two rod sleeves.

[0007] By adopting the above technical solution, after the installation of the middle ring, outer ring, and condenser lens is completed, one condenser lens under the external scanner is retained according to the usage needs. Then, the other condenser lens is removed by the staff by squeezing the rubber wheel and placed into the box. When replacing the condenser lens, the removed condenser lens is put back into its original position. Then, the unused condenser lenses are stored in the same way. The whole process does not require disassembling other parts that cooperate with the condenser lens, which improves the ease of loading and unloading.

[0008] In a preferred embodiment, the present invention can be further configured such that the length of the threaded rod is greater than the notch on the clamp, and the clamp is made of plastic material.

[0010] In a preferred embodiment, the present invention can be further configured such that: a storage mechanism is provided between the two rod sleeves, the storage mechanism including a box body connected between the two rod sleeves and a partition installed inside the box body, wherein the long side of the box body is larger than the diameter of the condenser lens.

[0011] In a preferred embodiment, the present invention can be further configured such that: both the top of the box and the partition are provided with an arc-shaped opening, which is located between the two rod sleeves.

[0012] In a preferred embodiment, the present invention can be further configured such that: a sealing ring is installed on the top and bottom of the middle ring and on the side of the outer ring near the middle ring, and the inner wall of the sealing ring is in contact with the outer wall of the condenser lens.

[0013] In a preferred embodiment, the present invention can be further configured such that a rubber wheel is sleeved on the outer side of the condensing lens, and the thickness of the rubber wheel is less than the distance between two adjacent sealing rings.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, after the installation of the middle ring, outer ring, and condenser lens is completed, one condenser lens under the external scanner is retained according to the usage needs. Then, the other condenser lens is removed by the staff by squeezing the rubber wheel and placed into the box. When replacing the condenser lens, the condenser lens that has been removed is put back into its original position. Then, the unused condenser lenses are stored in the same way. The whole process does not require disassembling other parts that cooperate with the condenser lens, which improves the ease of loading and unloading.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of a pathological slide scanner with a condenser lens.

[0031] Example 1:

[0032] Combination Figure 1-5 As shown, the present invention provides a condenser lens for a pathological slide scanner, including a condenser mechanism 100 and a mounting mechanism 200. The condenser mechanism 100 includes a middle ring 110, two outer rings 120 suspended at the top and bottom of the middle ring 110, and a condenser lens 130 attached between the outer rings 120 and the middle ring 110.

[0033] The mounting mechanism 200 includes a clamp 210 located at the top of the middle ring 110, a threaded rod 220 slidably passing through the clamp 210, two nuts 230 screwed to the threaded rod 220, two rod bodies 240 installed on one side of the clamp 210, a rod sleeve 250 sleeved at the bottom of the rod body 240, and a plurality of connecting rods 260 connected to the middle ring 110 and the outer ring 120, wherein the plurality of connecting rods 260 are respectively fixedly connected to the two rod sleeves 250.

[0034] Furthermore, the length of the threaded rod 220 is greater than the notch on the clamp 210, which is made of plastic material. The length of the threaded rod 220 is used to provide conditions for flexibly tightening the size of the clamp 210.

[0035] Furthermore, the two nuts 230 are respectively close to both ends of the threaded rod 220, and the clamp 210 is located between the two nuts 230. The layout design of the nuts 230 allows the inner diameter of the clamp 210 to shrink when the two nuts 230 are tightened, so that it can be firmly connected to the external scanner.

[0036] Example 2:

[0037] Combination Figure 1 As shown, based on Embodiment 1, a storage mechanism 300 is provided between the two rod sleeves 250. The storage mechanism 300 includes a box body 310 connected between the two rod sleeves 250 and a partition 320 installed inside the box body 310. The long side inside the box body 310 is larger than the diameter of the condenser lens 130. The box body 310 and the partition 320 cooperate to separate the two unused condenser lenses 130, thus protecting the condenser lenses 130 well.

[0038] Furthermore, both the top of the box body 310 and the partition 320 are provided with arc-shaped openings, which are located between the two rod sleeves 250. The arc-shaped openings facilitate the removal of the condensing lens 130 from the box body 310 by the staff.

[0039] Example 3:

[0040] Combination Figure 1 As shown, in the above embodiment, sealing rings 400 are installed on the top and bottom of the middle ring 110 and on the side of the outer ring 120 near the middle ring 110. The inner wall of the sealing ring 400 is in contact with the outer wall of the condensing lens 130. The sealing ring 400 can improve the sealing between the condensing lens 130 and the middle ring 110 and the outer ring 120.

[0041] Furthermore, a rubber wheel 500 is fitted onto the outer side of the focusing lens 130. The thickness of the rubber wheel 500 is less than the distance between two adjacent sealing rings 400. The rubber wheel 500 is provided to facilitate the operator's zooming operation.

[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the clamp 210 is fitted onto the external scanner, and then the nut 230 is tightened to reduce the clamp 210. Then, the rod body 240, the rod sleeve 250, and the connecting rod 260 cooperate to complete the stable installation of the middle ring 110, the outer ring 120, the condenser lens 130 and the external scanner. Then, according to the usage needs, one condenser lens 130 under the external scanner is retained. Then, the other condenser lens 130 can be removed from between the middle ring 110 and the outer ring 120 by the operator using the rubber wheel 500 and placed inside the box 310. At the same time, when replacing the condenser lens 130, the previously removed condenser lens 130 is put back into its original position. Then, the unused condenser lens 130 is stored in the same way. The whole process does not require disassembling other parts that cooperate with the condenser lens 130, which improves the ease of loading and unloading.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
