Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a positioning device for a pathological slide scanner. Background Technology

[0002] In the field of pathological diagnosis, the scanning and analysis of pathological slides is a crucial step, and the precise positioning of the slides directly affects the quality of the scanned images and the accuracy of the diagnosis. Traditional pathological slide scanners have many limitations in their positioning methods: some devices rely on manual placement of slides, which is not only inefficient but also prone to slide displacement due to operational errors, affecting scanning accuracy; even when mechanical positioning structures are used, the lack of flexibility in the moving mechanism often makes it difficult to achieve precise multi-directional movement of the slides within a plane, and cannot adapt to the gripping and transporting needs of slides of different sizes. At the same time, traditional mechanical gripping components are prone to mechanical damage to fragile slides due to rigid contact when gripping pathological slides, resulting in slide breakage or sample distortion; and during the slide placement process, the lack of an effective positioning guidance structure makes the slides prone to tilting. If the subsequent correction mechanism is not designed properly, either the correction force is insufficient to ensure accurate positioning, or the rigid contact further damages the slides. In addition, the components of existing positioning devices have poor linkage, and the movement, grasping, positioning, and correction processes are difficult to coordinate, resulting in low overall positioning efficiency and stability. This fails to meet the requirements of high precision, high efficiency, and low damage for pathological slide scanning. To address these issues, we propose a positioning device for a pathological slide scanner. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3 A positioning device for a pathological slide scanner includes a base plate 1, a mounting plate 2 fixedly installed at the center of the top of the base plate 1, and further includes:

[0028] A movable structure is fixedly installed at the top of the base plate 1;

[0029] A straightening structure 3 is fixedly installed on the top of the mounting plate 2 on the side opposite to the base plate 1, and three sets of positioning plates 4 are fixedly installed on the top of the mounting plate 2 on the side close to the base plate 1.

[0030] Furthermore, the movable structure includes a support rod 5, a first threaded screw 8, a first slide rod 9, and a first motor 10. Two sets of support rods 5 are fixedly installed on both sides of the top of the base plate 1, and the two sets of support rods 5 are symmetrical to each other.

[0031] A first sliding rod 9 is fixedly installed between the two sets of support rods 5, and a first threaded screw 8 is rotatably installed on the side of the two sets of support rods 5 close to the first sliding rod 9.

[0032] A first motor 10 is fixedly installed at one end of a set of support rods 5 near the first threaded screw 8, and the output shaft of the first motor 10 is fixedly installed together with the first threaded screw 8. By setting up a moving structure composed of support rods 5, the first threaded screw 8, the first slide bar 9 and the first motor 10, when the first motor 10 is started, it can drive the first threaded screw 8 to rotate, so that the mounting block 6 can slide stably along the first slide bar 9, realizing the precise translation of the mounting block 6 between the two sets of support rods 5. This structural design not only provides a stable support and guide for the subsequent lateral movement of the moving gripping plate 7, but also ensures the accuracy of the movement of the mounting block 6 through the precise control of the first motor 10, thus laying a good foundation for the gripping and positioning of pathological slides and improving the reliability and accuracy of the entire device in lateral movement.

[0033] Furthermore, the movable structure also includes a mounting block 6, a movable gripping plate 7, a second slide bar 11, a second threaded screw 12, and a second motor 13. A set of mounting blocks 6 is provided on the first threaded screw 8 and the first slide bar 9 on the two sets of support rods 5. The top ends of the two sets of mounting blocks 6 are slidably mounted on the first slide bar 9, and the mounting block 6 is provided with a threaded opening that meshes with the first threaded screw 8 on the side near the first threaded screw 8.

[0034] A second slide rod 11 is fixedly installed between the two sets of mounting blocks 6, and a second threaded screw 12 is rotatably installed on the side of the two sets of mounting blocks 6 near the second slide rod 11;

[0035] Furthermore, a second motor 13 is fixedly installed on one side of a set of mounting blocks 6 near the second threaded screw 12, and the output shaft of the second motor 13 is fixedly installed together with one end of the second threaded screw 12;

[0036] Two sets of mounting blocks 6 are equipped with movable gripping plates 7 via a second slide rod 11 and a second threaded screw 12. The top of the movable gripping plate 7 is slidably mounted with the second slide rod 11, and the bottom of the movable gripping plate 7 is provided with a threaded opening that meshes with the second threaded screw 12. When the second motor 13 is started, it can drive the second threaded screw 12 to rotate, allowing the movable gripping plate 7 to slide smoothly along the second slide rod 11, thus realizing the movement of the movable gripping plate 7 in another direction. In this way, the movable gripping plate 7 can complete multi-directional movement in the plane under the coordinated action of the first threaded screw 8 and the second threaded screw 12, which greatly improves the range of motion and flexibility of the movable gripping plate 7, enabling it to reach the placement position of the pathological slide more accurately, meeting the gripping needs of pathological slides in different positions, and enhancing the applicability of the device.

[0037] Furthermore, a set of pneumatic suction cups 15 are fixedly installed around the perimeter of the mobile gripping plate 7, and each set of pneumatic suction cups 15 has an air pipe interface at its top. The multiple sets of pneumatic suction cups 15 fixedly installed around the perimeter of the mobile gripping plate 7 can generate a strong suction force after being connected to the air circuit through the air pipe interface at the top, which can stably grip the pathological slides. Compared with the traditional mechanical gripping method, the pneumatic suction cups 15 can avoid causing mechanical damage to the pathological slides. At the same time, by controlling the air pressure, the suction force can be flexibly adjusted to ensure that the pathological slides will not fall off or shift during gripping and movement, thus improving the stability and safety of pathological slide gripping.

[0038] Furthermore, two sets of positioning plates 4 are fixedly installed horizontally at the top of the mounting plate 2, and one set of positioning plates 4 is fixedly installed vertically at the top of the mounting plate 2. A set of first rubber rollers 14 is rotatably installed on one side of each of the three sets of positioning plates 4. The three sets of positioning plates 4 at the top of the mounting plate 2, with two sets horizontally and one set vertically, form a positioning frame for the pathological slide. The first rubber rollers 14 rotatably installed on one side of the three sets of positioning plates 4 can contact and roll with the surface of the pathological slide during the placement or movement of the pathological slide. The rolling of the first rubber rollers 14 can not only reduce the friction between the pathological slide and the positioning plates 4 and avoid scratching the surface of the slide, but also play a certain guiding and limiting role for the pathological slide, ensuring that the initial position of the pathological slide on the mounting plate 2 is more regular, which is convenient for subsequent correction and scanning work.

[0039] Furthermore, the correction structure 3 includes a pneumatic strut 16, a third slide bar 17 and a sliding plate 18. The pneumatic strut 16 is fixedly installed on the side of the top of the mounting plate 2 away from the bottom plate 1.

[0040] A set of third slide rods 17 are fixedly installed on both sides of the mounting plate 2 near the pneumatic strut 16, and a set of sliding plates 18 are slidably installed between the two sets of third slide rods 17. The pneumatic strut 16 in the correction structure 3 can provide a stable driving force to drive the sliding plate 18 to slide along the third slide rod 17. The third slide rod 17 provides precise guidance for the sliding of the sliding plate 18, ensuring that the sliding plate 18 will not deviate during the movement, thereby ensuring the stability and accuracy of the correction structure 3 when it is working, and providing a reliable structural basis for subsequent correction operations on pathological slides.

[0041] Furthermore, the middle part of the sliding plate 18 is fixedly installed together with the output shaft of the pneumatic strut 16, and a support plate 19 is fixedly installed on the side of the sliding plate 18 away from the pneumatic strut 16.

[0042] Two sets of second rubber rollers 20 are rotatably mounted on the side of the support plate 19 away from the sliding plate 18 via a bracket. The sliding plate 18 is fixed to the output shaft of the pneumatic strut 16, so that the pneumatic strut 16 can accurately control the moving distance of the sliding plate 18. The two sets of second rubber rollers 20 rotatably mounted on the sliding plate 18 via the bracket can contact and roll with the surface of the pathological slide when the sliding plate 18 moves close to it. The setting of the second rubber rollers 20 can apply appropriate pressure by rolling when the pathological slide is corrected, so as to adjust the pathological slide to the correct position. At the same time, the rubber material has a certain elasticity, which can avoid hard damage to the pathological slide and effectively improve the accuracy of pathological slide positioning.

[0043] First, the first motor 10 is started. The output shaft of the first motor 10 drives the first threaded screw 8 to rotate. Since the mounting block 6 is engaged with the first threaded screw 8 and its top is slidably mounted on the first slide rod 9, the mounting block 6 will slide laterally along the first slide rod 9, achieving the effect of driving the mounting block 6 and related components to move laterally, providing a basis for the subsequent position adjustment of the moving gripping plate 7. Next, the second motor 13 is started. The output shaft of the second motor 13 drives the second threaded screw 12 to rotate. Since the moving gripping plate 7 is engaged with the second threaded screw 12 and its top is slidably mounted on the second slide rod 11, it will slide longitudinally along the second slide rod 11, forming the function of multi-directional movement of the moving gripping plate 7 in the plane, enabling it to accurately reach the placement position of the pathological slide. When the moving gripping plate 7 reaches above the pathological slide, it connects to the air circuit through the air pipe interface at the top of the pneumatic suction cup 15. The pneumatic suction cup 15 generates suction force to stably grip the pathological slide, avoiding mechanical damage to the pathological slide. At the same time, it can control the air pressure to ensure that the slide does not fall off or shift during the gripping process. After completion, the first motor 10 and the second motor 13 work together to move the moving gripper 7, transporting the pathological slide to the positioning frame formed by the three sets of positioning plates 4 at the top of the mounting plate 2. During the process of placing the pathological slide onto the mounting plate 2, the pathological slide will contact the first rubber roller 14 on one side of the three sets of positioning plates 4. The first rubber roller 14 rolls, reducing the friction between the pathological slide and the positioning plate 4, avoiding scratching the slide surface, and at the same time guiding and limiting the pathological slide to ensure that the initial position of the pathological slide is regular. Subsequently, the pneumatic strut 16 in the correction structure 3 is activated. The output shaft of the pneumatic strut 16 pushes the sliding plate 18 to slide along the third slide rod 17, ensuring that the sliding plate 18 moves stably without deviation. The sliding plate 18 drives the support plate 19 and the two sets of second rubber rollers 20 to approach the pathological slide. The second rubber rollers 20 contact the surface of the pathological slide and roll, applying appropriate pressure to adjust the pathological slide to the correct position. The rubber material avoids hard damage and effectively improves the accuracy of the pathological slide positioning, preparing for subsequent scanning work.
