A smart recognition and scanning device for histopathological images

Abstract

This utility model discloses an intelligent recognition and scanning device for histopathological images, comprising: a base plate, a support fixedly connected to the upper surface of the base plate, a slide rod fixedly connected to the lower surface of the support, a histopathological image scanning device body slidably connected to the slide rod, four lead screws rotatably connected to the upper surface of the base plate, each of the four lead screws having a ball threadedly connected to its outer wall, an anti-slip sleeve fixedly connected to the upper surface of the ball, and a placement plate with four ball grooves, the four balls being rotatably connected inside the four ball grooves respectively. Through the above components, the placement plate can be adjusted to multiple angles, which is equivalent to rotating the sample, allowing the lens to face the target area from multiple directions, avoiding detail obstruction or blurring caused by a fixed angle. Furthermore, since stained pathological sections are sensitive to the angle of light reflection, adjusting the angle of the placement plate can change the incident and reflection paths of light, reducing reflection and shadows.

Description

Technical Field

[0001] This utility model relates to the field of tissue pathology image scanning technology, and in particular to an intelligent recognition and scanning device for tissue pathology images. Background Technology

[0002] A smart recognition and scanning device for histopathological images is mainly used for automated and intelligent scanning and analysis of histopathological samples. It combines computer vision and artificial intelligence technologies to assist pathologists in completing diagnostic work more efficiently and accurately.

[0003] However, when using it, the placement plate of the existing equipment cannot be adjusted in angle, and the lens can only take pictures from a fixed horizontal direction. For obliquely distributed tissues, such as lesions in puncture biopsy and vascular invasion paths, only "side" or "oblique section" can be captured, which causes the morphology of cancer cell nuclei to be compressed. The nucleus, which should be round, is captured as an oval shape, affecting the judgment of the scanning device. Moreover, the boundary between tumor and normal tissue becomes blurred due to the angle problem, making it difficult for the scanning device to accurately segment the area. It is similar to taking a picture of a map at an oblique angle, which will distort the coastline. In addition, when scanning at a fixed angle, the reflection problem of stained sections cannot be avoided. Utility Model Content

[0004] The purpose of this invention is to solve at least one of the technical problems existing in the prior art, and to provide an intelligent recognition and scanning device for tissue pathology images, which solves the problems of sample detail obstruction and image reflection blur caused by the fixed scanning angle of the existing device.

[0005] This utility model also provides a histopathological image intelligent recognition and scanning device, comprising: a base plate, a support fixedly connected to the upper surface of the base plate, a slide rod fixedly connected to the lower surface of the support, a histopathological image scanning device body slidably connected to the slide rod, four lead screws rotatably connected to the upper surface of the base plate, each of the four lead screws having a ball threadedly connected to its outer wall, and an anti-slip sleeve fixedly connected to the upper surface of each ball; a placement plate, the placement plate having four ball grooves, and the four balls rotatably connected inside the four ball grooves respectively. Through the above components, via... The system consists of four lead screws. By rotating one of them, the lead screw moves a ball on it up and down. With the ball and the ball groove working together, one side of the placement plate will shift its angle as the ball moves up and down. By adjusting the height of the ball at different positions, the placement plate can be adjusted to various angles. Adjusting the angle of the placement plate is equivalent to rotating the sample, allowing the lens to face the target area from multiple directions. This avoids detail obstruction or blurring caused by a fixed angle. Furthermore, stained pathological sections are sensitive to the angle of light reflection. Adjusting the angle of the placement plate can change the light incident and reflection paths, reducing reflections and shadows.

[0006] According to the present invention, a tissue pathology image intelligent recognition and scanning device is provided, wherein a lifting frame is slidably connected to the outer wall of the slide rod, and the body of the tissue pathology image scanning device is fixedly connected to the inner surface of the lifting frame.

[0007] According to the present invention, a tissue pathology image intelligent recognition and scanning device is provided, wherein a lead screw is rotatably connected to the lower surface of the support, and the lifting frame is threadedly connected to the outer wall of the lead screw.

[0008] According to the present invention, in a histopathological image intelligent recognition and scanning device, the lower end of lead screw three and the outer wall of lead screw one are both fixedly connected with knobs.

[0009] According to the present invention, in a histopathological image intelligent recognition and scanning device, two support plates are fixedly connected to the upper surface of the placement plate, and a screw rod is threaded through the inner surface of each of the two support plates.

[0010] According to the present invention, in a histopathological image intelligent recognition and scanning device, one end of each of the two lead screws is rotatably connected to a clamp, and the clamp is made of rubber.

[0011] According to the present invention, in a histopathological image intelligent recognition and scanning device, a limit rod is fixedly connected to the rear surface of the clamp.

[0012] According to the present invention, a tissue pathology image intelligent recognition and scanning device is provided on the support plate, and the limiting rod is slidably connected inside the limiting hole. Beneficial effects

[0013] The intelligent recognition and scanning device for histopathological images in this technical solution uses four lead screws. By rotating one of them, the lead screw drives a ball on it to rise and fall. With the cooperation of the ball and the ball groove, one side of the placement plate will shift its angle according to the rise and fall of the ball. By adjusting the height of the ball at different positions, the placement plate can be adjusted to various angles. Adjusting the angle of the placement plate is equivalent to rotating the sample, allowing the lens to face the target area from multiple directions. This avoids detail obstruction or blurring caused by a fixed angle. Furthermore, the stained pathological slides are sensitive to the angle of light reflection. Adjusting the angle of the placement plate can change the light incident and reflection path, reducing reflection and shadows. Attached Figure Description

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4 This utility model provides an intelligent recognition and scanning device for histopathological images, comprising: a base plate 5, a bracket 14 fixedly connected to the upper surface of the base plate 5, a slide rod 16 fixedly connected to the lower surface of the bracket 14, a histopathological image scanning device body 1 slidably connected to the slide rod 16, a lifting frame 15 slidably connected to the outer wall of the slide rod 16, the histopathological image scanning device body 1 fixedly connected to the inner surface of the lifting frame 15, a lead screw 17 rotatably connected to the lower surface of the bracket 14, the lifting frame 15 threadedly connected to the outer wall of the lead screw 17, and knobs 8 fixedly connected to the lower end of the lead screw 17 and the outer wall of the lead screw 17.

[0018] Specifically: the bracket 14 is fixed on the base plate 5, the slide rod 16 is vertically installed on the lower surface of the bracket, and the scanning device body 1 is slidably connected to the slide rod 16 through the lifting frame 15. When the lead screw 17 is rotated, because the lifting frame 15 and the lead screw 17 are threadedly connected, the rotation of the lead screw 17 is converted into the up and down sliding of the lifting frame on the slide rod 16, thereby driving the scanning device body 1 to rise and fall synchronously, adjusting the vertical distance between the scanning device and the placement plate 6, adapting to pathological samples of different thicknesses, or adjusting the lens focal length to obtain clear images.

[0019] Specifically: The main body 1 of the histopathological image scanning device is a core component integrating a lens, a light source and an image sensor. The lens focuses the pathological sample, the light source provides uniform illumination, and the image sensor converts the optical signal into a digital image. Its working principle is to use the optical system to collect the sample image, combine it with the motor drive to realize the focus adjustment, and then transmit the data to the computer for processing through the circuit. This device is a mature technology and is therefore well known to those in the field, so it will not be described in detail in this article.

[0020] Four lead screws 7 are rotatably connected to the upper surface of the base plate 5. The outer walls of the four lead screws 7 are threaded with balls 4. The upper surface of the balls 4 is fixedly connected with anti-slip sleeves 2 and a placement plate 6. The placement plate 6 is provided with four ball grooves 3. The four balls 4 are rotatably connected inside the four ball grooves 3 respectively.

[0021] Specifically: Four lead screws 7 are distributed on the base plate 5. The outer wall of each lead screw is threaded to a ball 4, which is embedded in the ball groove 3 of the placement plate 6. An anti-slip sleeve 2 is fixedly connected to the upper surface of the ball 4. During use, the user needs to squeeze the anti-slip sleeve 2 to prevent the ball 4 from being rotated by the lead screw, ensuring that the ball will rise and fall along the lead screw when the lead screw 7 is rotated. Since the ball and the ball groove are rotatably connected, the corresponding side of the placement plate will tilt with the change of the ball's height. By adjusting the different heights of the four lead screws, various tilt angles of the placement plate can be combined. By changing the angle of the placement plate, multi-angle adjustment of the pathological sample can be achieved, allowing the scanning lens to face the target area from different directions, avoiding detail obstruction caused by a fixed angle. At the same time, the incident angle of light can be adjusted to reduce reflection and shadows on the stained sections and improve image quality.

[0022] Two support plates 9 are fixedly connected to the upper surface of the placement plate 6. The inner surfaces of the two support plates 9 are threaded with screw rods 11. The opposite ends of the two screw rods 11 are rotatably connected to clamping plates 13. The clamping plates 13 are made of rubber. The rear surface of the clamping plates 13 is fixedly connected to a limiting rod 10. The support plates 9 are provided with limiting holes 12. The limiting rod 10 is slidably connected inside the limiting holes 12.

[0023] Specifically: The support plate 9 on the placement plate 6 passes through the lead screw 11. One end of the lead screw 11 is connected to the rubber clamp 13, and the other end is exposed for easy rotation. The limiting rod 10 is fixed to the rear surface of the clamp and inserted into the limiting hole 12 of the support plate. When the lead screw 11 is rotated, the axial movement of the lead screw causes the clamp to slide linearly along the limiting rod, and the two clamps on both sides clamp the pathological sample. The rubber material can avoid sample damage, and the limiting rod ensures stable movement of the clamp, prevents sample displacement, and firmly fixes pathological slides of different sizes, avoiding sample shaking during scanning and causing image blurring, thus ensuring scanning accuracy.

[0024] Working principle: Four lead screws 7 are distributed on the base plate 5. The outer wall of the lead screw is threaded to a ball 4, which is embedded in the ball groove 3 of the placement plate 6. The upper surface of the ball 4 is fixedly connected to an anti-slip sleeve 2. During use, the user needs to squeeze the anti-slip sleeve 2 to prevent the ball 4 from being rotated by the lead screw. This ensures that when the lead screw 7 is rotated, the ball will rise and fall along the lead screw. Since the ball and the ball groove are rotatably connected, the corresponding side of the placement plate will tilt with the change of the ball's height. By adjusting the different heights of the four lead screws, various tilt angles of the placement plate can be combined. By changing the angle of the placement plate, multi-angle adjustment of the pathological sample can be achieved, allowing the scanning lens to face the target area from different directions, avoiding detail obstruction caused by a fixed angle. At the same time, the incident angle of light can be adjusted to reduce reflection and shadows on the stained sections and improve image quality.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
