[0002] In the process of pathological sampling, accurately determining the cutting position of tissue sections is crucial.

[0003] Traditional pathological section preparation typically relies on the experience and visual observation of the sectioner, who repeatedly and carefully confirms the cutting position. This is not only inefficient but also prone to human error, leading to deviations in the cutting position and affecting the accuracy of pathological test results. Existing auxiliary tools, such as rulers or manual marking, are ill-suited for complex-shaped tissue samples, and the marking process is cumbersome, making it difficult to provide real-time, intuitive cutting guidance. Therefore, inventing a pathological section preparation device to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0027] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a pathological tissue sampling device, comprising...

[0028] The connecting mechanism 100 includes a mounting frame 110, the bottom of which is mounted on one side of the slicer of the pathological slide collection device. The collection auxiliary mechanism 200 includes a sliding mounting shell 210, which is slidably mounted on the inner side of the mounting frame 110. A cutting auxiliary line assembly 220 is fixedly mounted below the sliding mounting shell 210. The cutting auxiliary line assembly 220 includes a laser diode 223, and a micro cylindrical lens 222 is correspondingly arranged on the outer side of the laser diode 223. The laser diode 223 and the micro cylindrical lens 222 are configured in conjunction with the slicer of the pathological slide collection device. Through the cooperation of the laser diode 223 and the micro cylindrical lens 222, a clear laser line can be emitted, intuitively indicating the cutting position, avoiding cutting deviations caused by visual judgment errors of the slicer, and significantly improving the accuracy of pathological slide collection.

[0029] Please see Figure 3 and Figure 4 The mounting bracket 110 includes a vertical plate 111. An arc-shaped slide rail 112 is fixedly connected to the top of the vertical plate 111, and a connecting plate 113 is fixedly connected to the bottom of the vertical plate 111. The connecting plate 113 is installed on one side of the microtome blade of the pathological slide sampling device. The connecting plate 113 is angled, and through holes are provided on its top surface and both sides of its vertical surface. These through holes are used for bolt installation, and the plate is installed on one side of the blade to facilitate alignment of the emitted laser with the blade's cutting position. The arc-shaped slide rail 112 is arc-shaped, and a strip-shaped through hole is provided in its center.

[0030] The sliding mounting housing 210 includes a cover plate 211. A vertical rod 212 is fixedly connected to the back of the cover plate 211. The vertical rod 212 passes through the strip-shaped through hole in the middle of the arc-shaped slide rail 112. A limit ring 213 is threaded onto the outside of the vertical rod 212. The limit ring 213 abuts against the outside of the arc-shaped slide rail 112. At least two vertical rods 212 are provided as needed, and the two are respectively set at both ends of the back of the cover plate 211 to facilitate stable sliding. At the same time, the limit ring 213 can be screwed to position or release the position.

[0031] A limiting gasket 214 is fixedly connected to the side of the limiting ring 213 near the cover plate 211. The limiting gasket 214 is sleeved on the outside of the upright 212 and abuts against the arc-shaped slide rail 112. The limiting gasket 214 is made of elastic rubber material, which facilitates positioning.

[0032] The cutting auxiliary line assembly 220 also includes a lens mounting shell 221, which is connected to the cover plate 211. A rectangular through hole is provided in the middle of the lens mounting shell 221. A miniature cylindrical lens 222 is embedded in the rectangular through hole of the lens mounting shell 221. A laser diode 223 is installed inside the lens mounting shell 221. The laser diode 223 is correspondingly arranged with the miniature cylindrical lens 222.

[0033] The lens mounting housing 221 is an isosceles trapezoid. Miniature cylindrical lenses 222 are embedded in the two sides and top surface of the lens mounting housing 221, and these miniature cylindrical lenses 222 are correspondingly positioned with the laser diode 223. The cover plate 211 is arc-shaped and engages with the outer side of the lens mounting housing 221. The bottom surface of the lens mounting housing 221 has an obtuse-angled cut to provide ample space for placing samples with cut edges.

[0034] A power supply and control structure is also provided between the cover plate 211 and the lens mounting shell 221: a built-in rechargeable lithium battery and charging interface; a power switch and control circuit board are designed to realize laser on / off and mode switching. At the same time, a laser adjustment structure can be added: a laser intensity adjustment knob is added to adapt to different lighting environments; a laser angle fine-tuning component is set to deal with complex sample cross-sections.

[0035] Meanwhile, the slicing device can be a slicing device in the prior art, similar to a pathological tissue sampling slicing device with application number CN202222893065.6. The structure of the mounting frame 110 can be improved as needed to facilitate installation on various slicing devices, and the size and shape can be modified according to different slicing devices.

[0036] Working principle: When using the pathological sampling device, the mounting bracket 110 of the connecting mechanism 100 is first fixed to one side of the slicer of the pathological slide sampling device using bolts through the through hole on the connecting plate 113, thus completing the installation of the device. When it is necessary to sample tissue samples, according to the shape of the sample and the cutting requirements, the upright 212 can be slid along the strip-shaped through hole in the middle of the arc-shaped slide rail 112 by rotating the limiting ring 213, thereby driving the sliding mounting shell 210 to move inside the mounting bracket 110, thereby adjusting the position and angle of the cutting auxiliary line assembly 220.

[0037] After adjustment, tighten the limiting ring 213 again, and use the limiting shim 214 to stably fix the sliding mounting shell 210 onto the arc-shaped slide rail 112. At this point, the sample to be sectioned is placed between the cutting guide line assembly 220 and the microtome blade. The laser diode 223 is activated, and the emitted light is collimated and shaped by the corresponding micro-cylindrical lens 222 inside the lens mounting shell 221, projecting a clear laser line onto the sample surface to clearly indicate the cutting position. The sectioning personnel only need to follow the laser line guide and operate the microtome blade to perform the cutting operation, thus quickly and accurately completing the pathological sampling.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
