Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a pathological specimen collection device. Background Technology

[0002] Pathological specimen collection is a crucial preliminary step in pathological diagnosis. It requires using a sampling device to cut the specimen into tissue blocks of uniform thickness. The position and integrity of these sections directly determine the accuracy of subsequent staining observation and diagnostic results. Clinically, pathological specimens are diverse, including fragile puncture specimens with a diameter of 0.5 to 1 cm, as well as irregular surgical specimens with side lengths of 3 to 8 cm. These types of specimens are prone to displacement due to external forces during the sectioning process, which can affect the quality of the sample collection.

[0003] Currently, the anti-deviation design of pathological specimen collection devices used in medical institutions generally has significant deficiencies. Existing devices mostly define rectangular placement areas on the workbench surface. For example, a pathology specimen collection device with Chinese application number CN201921798912.2 has a collection plate for placing pathological tissues. However, the collection plate is made of ceramic, which easily leads to specimen slippage, especially for soft specimens. This affects the quality of the collection and causes inconvenience for subsequent testing and diagnosis.

[0004] To address the above shortcomings, further improvements are needed to the sampling device to mitigate the issue of pathological specimens easily shifting during sectioning. Utility Model Content

[0005] This invention aims to overcome the problem of pathological specimens easily shifting during slicing by the sampling device, and provides a pathological specimen sampling device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pathological specimen collection device, including a workbench, a placement area for placing pathological specimens on the workbench, a slicing device on the workbench, a limiting structure for limiting the pathological specimens in the horizontal direction on the workbench, the slicing device for slicing the pathological specimens in the placement area, and a positioning structure for fixing the pathological specimens in the vertical direction on the workbench.

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.

[0020] Please see Figure 1-7 A pathological specimen collection device includes a workbench 1, a placement area 11 for placing pathological specimens on the workbench 1, a slicing device 2 on the workbench 1, and a limiting structure 3 on the workbench 1 for horizontally limiting the pathological specimens. The slicing device 2 is used to slice the pathological specimens in the placement area 11. The workbench 1 is provided with a positioning structure 4 for vertically fixing the pathological specimens. The limiting structure can prevent the pathological specimens from shifting horizontally, while the positioning structure can prevent the pathological specimens from shifting vertically. This effectively avoids the problem of the pathological specimens shifting when being sliced.

[0021] Furthermore, the limiting structure 3 includes two limiting members 31, which are located on both sides of the placement area 11. The sides of the two limiting members 31 are in contact with the pathological specimens in the placement area 11. The two limiting members 31 are movably connected to the worktable 1. The sides of the limiting members 31 are in contact with the specimens. The contact side of the limiting members can be designed as a plane to increase the contact area and improve the limiting stability. The two limiting members 31 are movably connected to the worktable 1. By adjusting the distance between the limiting members 31, specimens of different sizes can be adapted.

[0022] In other embodiments: the side of the limiting member 31 can be an arc shape that adapts to the contour of the pathological specimen, so that the limiting member 31 fits the pathological specimen better.

[0023] Specifically: the limiting component 31 includes a limiting plate 311, and a sliding component 12 is provided on the worktable 1. The sliding component 12 can be relatively away from or relatively close to the placement area 11. The limiting plate 311 and the sliding component 12 are detachably connected. The sliding component 12 can be designed as a slider, so that the sliding component can be relatively close to or away from the placement area 11. At the same time, the limiting plate 311 and the sliding component 12 are detachably connected. The specific connection method can be bolts to enable the sliding component 12 to drive the limiting plate 311 to move, thereby adjusting the distance between the two limiting plates.

[0024] In other embodiments: the movement of the slider 12 can be achieved manually or electrically. The electric movement can be achieved by an electric push rod or a transmission connection driven by a motor, etc. The electric push rod can directly push the slider to move, which can reduce the use of manual labor.

[0025] In some embodiments: a slide groove 121 is provided on the workbench 1 for the sliding member 12 to move on. A baffle 122 protrudes from the side wall of the slide groove 121. The sliding member 12 abuts against the baffle 122. The slide groove 121 can be designed with a T-shaped cross section. The size of the slide groove 121 is adapted to the sliding member 12 to ensure smooth sliding without obvious shaking. The length of the slide groove can cover the adjustment needs on both sides of the placement area 11. The baffle 122 can be integrally formed with the workbench 1. The abutment between the sliding member 12 and the baffle 122 can form a guiding and anti-drop effect, ensuring that the sliding member can only move in the horizontal direction.

[0026] In other embodiments: the shape of the slide groove 121 can be dovetail-shaped. The dovetail-shaped slide groove can also play the role of preventing it from falling off. Similarly, the shape of the sliding member is also adapted to the shape of the slide groove, so as to prevent the sliding member 12 from falling off the slide groove.

[0027] In other embodiments: the baffle 122 can be fixedly connected to the worktable 1, and the vertical movement of the slider 12 is restricted by its height and thickness.

[0028] Furthermore: The sliding member 12 is provided with a screw 123, and the limiting plate 311 is provided with a connecting plate 312 on the side near the sliding member 12. The end of the screw 123 passes through the connecting plate 312. The connecting plate 312 is provided with a threaded part 313 that is threadedly connected to the screw 123. The connecting plate and the limiting plate are integrally formed, and a through hole for the screw to pass through is opened on it. The threaded part 313 that is threadedly connected to the screw can be a threaded sleeve with a handle. In this way, the threaded part can be disengaged from the screw by engaging with the screw thread, releasing the pressure on the connecting plate 312, thereby allowing the limiting plate to separate from the sliding member 12.

[0029] More specifically: The workbench 1 is provided with a placement platform 13, and the placement area 11 and the limiting structure 3 are both located on the placement platform 13. The placement platform 13 is provided with a protective cover 131 to prevent splashing of pathological specimens. The placement platform 13 is provided with multiple anti-slip parts 134 to prevent the pathological specimens from moving. The multiple anti-slip parts 134 are distributed at intervals along the horizontal axis of the placement platform 13. The protective cover 131 has an opening 132 for the blade 22 to pass through. One side of the protective cover 131 has a placement port 133 for the pathological specimen to move to the placement area. The protective cover can block specimen debris and tissue fluid splashing. The protective cover 131 and the placement platform 13 are detachably connected. The shape of the opening 132 is adapted to the movement trajectory of the blade, and the size of the opening 132 is slightly larger than the blade to ensure that the blade passes through smoothly and reduce splashing. At the same time, the placement port 133 on one side of the protective cover is provided for the specimen to be placed in. The size meets the requirements of the largest specimen. Furthermore, a protective door with a hinged connection can be provided at the placement port of the protective cover.

[0030] In some embodiments, the slicing device 2 includes an electric push rod 21 mounted on the worktable 1. One end of the electric push rod 21 near the limiting structure 3 is provided with a blade 22 for cutting pathological specimens. The blade 22 and the electric push rod 21 are detachably connected. A locking structure 23 is provided between the electric push rod 21 and the blade 22. The blade 22 is detachably connected to the electric push rod 21 via the locking structure 23. The electric push rod 21 can be controlled by a manual button or a foot switch. The detachable connection between the blade and the electric push rod facilitates replacement and sterilization. The locking structure is specifically designed with a protrusion on the electric push rod and a groove on the blade, and the protrusion and groove are fixed together by an interference fit, thereby ensuring that the disassembly and assembly of the blade are not overly complicated.

[0031] Furthermore, the locking structure can be a flexible snap-fit, which allows for quick disassembly and installation of the blade while ensuring a secure and loose connection between the blade and the electric actuator.

[0032] Specifically, the positioning structure 4 includes multiple positioning elements 41. The positioning elements 41 are used to penetrate the pathological specimen. The end of the positioning element 41 near the placement stage 13 is connected to the placement stage 13. The positioning element 41 is specifically a barb. After the barb penetrates into the pathological specimen, it prevents the pathological specimen from shifting, so that the pathological specimen can be sliced ​​evenly. By connecting the positioning element to the placement stage, it prevents the specimen from tilting upward or shifting horizontally when slicing. It is especially suitable for soft and easily deformable specimens. At the same time, the positioning element 41 and the blade are staggered, so it will not affect the cutting of the blade.

[0033] The specific material-collecting process of this material-collecting device is as follows: First, place the pathological specimen on the placement area 11. At the same time, the positioning component 41 will penetrate into the pathological specimen. After placement, move the limiting plate so that the limiting plate contacts the pathological specimen and limits the pathological specimen. After the pathological specimen is fixed, start the electric push rod. After the electric push rod is started, it will drive the blade to move towards the pathological specimen to slice and collect material. When the blade cuts the pathological specimen, it will contact the anti-slip component. The anti-slip component can prevent the pathological specimen from sliding and also prevent the blade from colliding with the placement stage, which can effectively extend the service life of the blade.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
