Description

Technical field

[0001] The utility model relates to the technical field of medical pathological-diagnostic devices, in particular to a pathological-diagnostic observation table for thyroid and breast tissue. State of the art

[0002] The pathology-diagnostic observation table is a central medical device for the microscopic observation and qualitative diagnosis of excised tissue samples following pathological biopsies of thyroid and breast diseases. Its core function is to provide a stable support surface as well as precise alignment and adjustment capabilities for the pathological tissue sections. In combination with microscopic observation devices, it enables magnified viewing and feature analysis of lesion areas. Therefore, it is an indispensable piece of equipment for the pathology department when performing screening and diagnostic work on benign and malignant thyroid and breast lesions.

[0003] Existing pathology-diagnostic observation tables typically consist of a fixed base, a fixed slide stage, and a microscope stand that is either non-adjustable or only height-adjustable. The slide stage allows only simple manual movement without an orthogonally arranged two-dimensional fine adjustment mechanism. The microscope stand permits only coarse height adjustment, preventing multi-stage focus adjustment combining coarse and fine adjustments. When observing thyroid and breast tissue specimens, precise alignment with lesion areas on the sections is difficult, the workflow is cumbersome, and observation efficiency is low. Furthermore, alignment errors can easily lead to overlooking small lesions, thus failing to meet the requirements for highly precise pathological diagnostics of thyroid and breast diseases. Subject of the utility model

[0004] To solve the aforementioned problems in the prior art, the purpose of the present utility model is to provide a pathological-diagnostic observation table for thyroid and breast tissue that allows multidimensional and multi-stage fine adjustment, improves the accuracy and efficiency of pathological observation, and reduces diagnostic errors.

[0005] The one or more technical solutions provided in the embodiment examples of the present application exhibit at least the following technical effects or advantages over the prior art: By arranging an XY two-dimensional fine adjustment slide component on the support base, the present utility model enables precise fine adjustment of thyroid and mammary gland specimens in two orthogonal directions X and Y within the horizontal plane for accurate positioning of the lesion area.

[0006] A Z-axis lifting column, combined with a swivel arm, enables coarse vertical height adjustment of the microscopic objective component. This, in conjunction with the objective's fine focus adjustment mechanism, allows for multi-stage vertical focus adjustment. This facilitates rapid and precise alignment between the sample and the observation objective, significantly simplifying the workflow of pathological observation and increasing both efficiency and accuracy. The system effectively prevents the overlooking of small lesions due to alignment errors, reducing errors in the pathological diagnosis of thyroid and breast diseases and thus meeting the demands of highly precise pathological diagnostics.

Furthermore, they will be obvious to a person skilled in the art to some extent based on the following examination or can be learned from the use of the present utility model.

[0012] A pathological-diagnostic observation table for the thyroid and mammary gland, as described in this example, comprises according to Fig. 1. A support base 1. The support base 1 is a rigid, cuboid-shaped base that serves as the mounting base for the entire device and provides stable support for all functional components. A two-dimensional XY fine-adjustment specimen holder component 2 and a Z-axis lifting column 3 are permanently attached to the top of the support base 1. The two-dimensional XY fine-adjustment specimen holder component 2 is used to hold and adjust the horizontal position of thyroid and breast gland specimens, while the Z-axis lifting column 3 is used to mount the observation component and adjust its vertical height.

[0013] The Z-axis lifting column 3 is a vertically arranged rod-shaped structure on which a swivel arm 31 is slidably mounted. The swivel arm 31 is axially displaceable up and down along the Z-axis lifting column 3. A microscopic objective component 32 is fixedly attached to the end of the swivel arm 31, the viewing end of which is oriented vertically downwards towards the XY two-dimensional fine adjustment slide component 2, so that the viewing field completely covers the adjustment range of the slide.

[0014] As in Fig. As shown in Figure 2, the XY two-dimensional fine adjustment slide component 2 comprises an orthogonally arranged X-axis fine adjustment mechanism 21 and a Y-axis fine adjustment mechanism 22. The fixed part of the X-axis fine adjustment mechanism 21 is attached to the support base 1, while the fixed part of the Y-axis fine adjustment mechanism 22 is mounted on the movable part of the X-axis fine adjustment mechanism 21, thus forming an orthogonal two-dimensional adjustment structure. A slide platform 23 is attached to the upper movable part of the Y-axis fine adjustment mechanism 22. This platform serves to hold thyroid and mammary gland specimens and allows precise displacement in two perpendicular directions within the horizontal plane by adjusting the X-axis fine adjustment mechanism 21 and the Y-axis fine adjustment mechanism 22.

[0015] As in Fig. As shown in Figure 3, the X-axis fine adjustment mechanism 21 comprises an X-axis fine adjustment spindle, an X-axis sliding carriage, and an X-axis locking knob. The X-axis fine adjustment spindle is drive-connected to the X-axis sliding carriage; by rotating the X-axis fine adjustment spindle, the X-axis sliding carriage can be driven uniformly in the X direction. The X-axis locking knob serves to lock the position of the carriage to prevent displacement errors during observation. The Y-axis fine adjustment mechanism 22 comprises a Y-axis fine adjustment spindle, a U-shaped guide rail base, and a Y-axis locking knob. The Y-axis fine adjustment spindle is drive-connected to the specimen platform 23. By turning the Y-axis fine adjustment spindle, the object carrier platform 23 can be driven evenly in the Y direction.The Y-axis locking knob is used to lock the position of the slide platform 23 in order to ensure stability during the observation process.

[0016] As in Fig. As shown in Figure 4, the side wall of the Z-axis lifting column 3 has a drive rack. Inside the swivel arm 31, a drive gear meshing with the drive rack is installed, and on the outside of the swivel arm 31 is a stroke adjustment handwheel that is coaxially connected to the drive gear. By turning the stroke adjustment handwheel, the swivel arm 31 can be moved up and down along the Z-axis lifting column 3 via a rack and pinion transmission, thereby achieving a coarse height adjustment of the microscopic objective component 32. The swivel arm 31 is also equipped with a swivel arm locking handwheel for locking the height position of the swivel arm 31.

[0017] At the end of the swivel arm 31, a clamp-like objective holder is provided, with the microscopic objective component 32 being firmly mounted in the objective holder by means of an objective locking knob, which allows for easy assembly and disassembly as well as stable attachment. The microscopic objective component 32 is equipped with a fine focus adjustment mechanism which, in combination with the coarse height adjustment of the swivel arm 31, enables multi-stage focus adjustment in the vertical direction and further improves observation accuracy.

[0018] The surface of the slide platform 23 has several threaded holes for the attachment of pathological samples, which can be adapted to pathological specimen holders of different specifications and meet the attachment requirements of thyroid and breast specimens of various dimensions.

[0019] When using the device, the thyroid and mammary gland specimen to be observed is attached to the slide platform 23. By adjusting the X-axis fine adjustment mechanism 21 and the Y-axis fine adjustment mechanism 22, the area of ​​the specimen to be observed is moved into the field of view of the microscopic objective component 32. By turning the stroke adjustment handwheel, the height of the swivel arm 31 is adjusted, resulting in a coarse vertical adjustment of the observation objective. Subsequently, precise focusing is achieved using the fine focus adjustment mechanism of the microscopic objective component 32, after which pathological observation and diagnosis can be carried out. After adjustment, the positions of the respective adjustment mechanisms can be locked using corresponding locking knobs to ensure stability during the observation process.

[0020] Although the present utility model has been disclosed as above with reference to preferred embodiments, this does not serve to limit the scope of the present utility model. Any person skilled in the art can make numerous modifications and adaptations without departing from the spirit and scope of the present utility model. Therefore, the scope of protection of the present utility model shall be governed by the provisions set out in the patent claims.
