Description

Technical Field

[0001] The utility model relates to the technical field of pathological slicers, and specifically relates to a pathological slicer. Background Art

[0002] Pathological sections are mainly used for pathological diagnosis. Artificial sections observed under a microscope make pathological tissues visible, facilitating the observation of pathological tissues under the microscope and pathological diagnosis. Pathological sections are also for easy observation and preservation. Pathological sections are made by using a specific slicer to slice the excised human pathological tissues, not cutting flesh on the body. Pathological sections usually wrap the pathological tissues (generally the excised pathological tissues from the human body) with paraffin, then use a pathological slicer to cut them into thin slices, then use special staining agents for staining, and finally observe the cell changes on a microscope to diagnose the nature of the lesion.

[0003] During the use of existing pathological sections, two clamping plates are usually used to clamp the pathological tissues to ensure the stability and accuracy of the slicing process. As the use time increases, the pathological tissues are gradually consumed. At this time, the pathological tissues clamped by the clamping plates are inconvenient for subsequent slicing operations due to the influence of the clamping plates. The existing method often adjusts manually, and when adjusting manually, the direct contact between the operator and the pathological block may contaminate the pathological tissues. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pathological slicer to solve the problems raised in the above background art.

[0005] To solve the above technical problems, a pathological slicer provided by the utility model includes a slicer body and a fixed tool rest connected to the slicer body. An adjusting component is arranged in the slicer body. The adjusting component includes a first driving gear rotatably arranged on the slicer body. Both sides of the first driving gear are meshed with transmission racks. The two ends of the two transmission racks are respectively connected with a pathological tissue placement plate and a pushing plate. When the first driving gear rotates to a certain position, it drives the pushing plate and the pathological tissue placement plate to move horizontally in opposite directions.

[0006] Furthermore, it further includes a driving component. The driving component includes a driven gear that drives the first driving gear to rotate synchronously. A rotating shaft is rotatably connected to the slicer body. A plurality of second driving gears are connected to the rotating shaft. The inner diameters of the plurality of second driving gears decrease sequentially along the central axis direction of the rotating shaft.

[0007] Furthermore, a connecting frame is connected to one side of the slicer body. The first driving gear is rotatably connected in the connecting frame, and the transmission rack is slidably connected in the connecting frame.

[0008] Further, a fixing frame is connected to one side of the slicer body. The driving assembly is rotatably connected within the fixing frame. A connecting spring is connected within the fixing frame, and the other end of the connecting spring is connected to a moving frame. The rotating shaft and the second driving gear are rotatably connected within the moving frame. One end of the rotating shaft is connected to a telescopic rod, and the telescopic rod is rotatably connected within the moving frame.

[0009] Further, a connecting shaft is rotatably connected within the fixing frame, and the driven gear is connected to the connecting shaft. A mounting shaft is rotatably connected within the connecting frame, and the first driving gear is connected to the mounting shaft. Synchronous wheels are connected to both the connecting shaft and the mounting shaft, and a synchronous belt is drivingly connected between the two synchronous wheels.

[0010] Further, a guiding block is connected to one side of the transmission rack, and the guiding block is slidably connected within the connecting frame. A sliding groove for the guiding block to slide is formed within the connecting frame.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By rotating the first driving gear to drive the two transmission racks to horizontally move in opposite directions, at this time, the push plate can push out the diseased tissue, while the pathological tissue placement plate can retract, avoiding movement conflicts with the pathological tissue placement plate when the blade on the fixed tool rest slices the pathological tissue. This setting can adjust the slicing position of the pathological tissue without contact, avoiding the situation of contaminating the diseased tissue.

[0013] 2. The rotating shaft can be used to drive the driven gear to rotate, and during the rotation of the driven gear, the first driving gear can be driven to rotate. In the actual use process, different second driving gears can be selected to mesh with the driven gear according to the hardness and size of different pathological tissues, so as to conveniently control the force for pushing the pathological tissue.

[0022] An adjusting component 3 is provided inside the slicing machine body 1. The adjusting component 3 includes a first driving gear 301 rotatably arranged on the slicing machine body 1. Both sides of the first driving gear 301 are meshingly connected with transmission racks 302. The two ends of the two transmission racks 302 are respectively connected with a pathological tissue placement plate 303 and a pushing plate 304. When the first driving gear 301 rotates to a certain position, it drives the pushing plate 304 and the pathological tissue placement plate 303 to perform horizontal movements in opposite directions.

[0023] It should be further noted that, referring to Figure 3 , in order to facilitate the support of the pathological tissue placement plate 303, a guide rail is connected to one side of the slicing machine body 1, and the pathological tissue placement plate 303 is slidably connected to the guide rail.

[0024] Specifically, the adjustment component 3 is provided so that the operator can move the position of the diseased tissue without directly contacting the diseased tissue, avoiding possible contamination of the diseased tissue and also facilitating the movement of the position of the diseased tissue. First, the positioning of the diseased tissue by the positioning member is released, and then the first driving gear 301 is rotated to drive the two transmission racks 302 to move horizontally in opposite directions. At this time, the push plate 304 can push out the diseased tissue, and the pathological tissue placement plate 303 can retract to avoid movement conflicts with the pathological tissue placement plate 303 when the blade slices on the fixed tool rest 2. This setting can adjust the slicing position of the pathological tissue without contact, avoiding the situation of contaminating the diseased tissue.

[0025] Reference Figure 2 , for the convenience of installing the first driving gear 301 and the transmission rack 302, a connection frame 6 is connected to one side of the slicing machine body 1. The first driving gear 301 is rotatably connected in the connection frame 6, and the transmission rack 302 is slidably connected in the connection frame 6. To avoid the connection frame 6 affecting the installation of the positioning member, in this embodiment, the connection frame 6 is installed between the two clamping plates 13.

[0026] Further, to ensure the stability of the sliding of the transmission rack 302, please continue to refer to Figure 3 , a guide block 5 is connected to one side of the transmission rack 302. The guide block 5 is slidably connected in the connection frame 6, and a sliding groove for the guide block 5 to slide is provided in the connection frame 6; two guide blocks 5 are provided and are respectively connected to one side of the two transmission racks 302. The provided guide blocks 5 can limit and guide the movement of the transmission rack 302. At the same time, an "L"-shaped connecting frame can be connected to one of the transmission racks 302, and the other end is connected to the pathological tissue placement plate 303, so as to facilitate driving the pathological tissue placement plate 303 to move.

[0027] Embodiment 2, on the basis of Embodiment 1

[0028] Considering that the hardness and size of different pathological tissues may be different, in order to avoid damaging the pathological tissue due to excessive force or the diseased tissue not being able to be pushed out due to insufficient force, it is necessary to further disclose the structure in the driving component 4. Please continue to refer to Figure 3 、 Figure 4 And Figure 5 , it further includes a driving component 4. The driving component 4 includes a driven gear 401 that drives the first driving gear 301 to rotate synchronously. A rotating shaft 402 is rotatably connected to the slicing machine body 1, and a plurality of second driving gears 403 are connected to the rotating shaft 402. The inner diameters of the plurality of second driving gears 403 decrease in sequence along the central axis direction of the rotating shaft 402;

[0029] Please refer to Figure 3In order to conveniently drive the first driving gear 301 to rotate and connect the components in the adjustment component 3 and the driving component 4 in series, a connecting shaft is rotatably connected in the fixed frame 15, and the driven gear 401 is connected to the connecting shaft. A mounting shaft is rotatably connected in the connecting frame 6, and the first driving gear 301 is connected to the mounting shaft. Both the connecting shaft and the mounting shaft are connected with a synchronous wheel 7, and a synchronous belt 8 is transmission-connected between the two synchronous wheels 7; the synchronous wheel 7 and the synchronous belt 8 can be used in combination to make the first driving gear 301 rotate as the driven gear 401 rotates.

[0030] Specifically, the rotating shaft 402 can drive the driven gear 401 to rotate, and the driven gear 401 can drive the first driving gear 301 to rotate during the rotation. During actual use, different second driving gears 403 can be selected to mesh with the driven gear 401 according to the hardness and size of different pathological tissues, thereby facilitating the control of the force of pushing the pathological tissue.

[0031] Please continue to refer to Figure 3 and Figure 5 A fixed frame 15 is connected to one side of the slicer body 1, and the driving component 4 is rotatably connected in the fixed frame 15. A connecting spring 10 is connected in the fixed frame 15, and the other end of the connecting spring 10 is connected to the moving frame 9. The rotating shaft 402 and the second driving gear 403 are rotatably connected in the moving frame 9, and one end of the rotating shaft 402 is connected to a telescopic rod 11, and the telescopic rod 11 is rotatably connected in the moving frame 9; the fixed frame 15 provided first is convenient for installing the components in the driving component 4, and the connecting spring 10 provided at the same time can make the second driving gear 403 and the driven gear 401 conflict with each other and mesh. At the same time, when it is necessary to replace the second driving gear 403 of other inner diameters to mesh with the driven gear 401, force can be applied to overcome the elastic force of the connecting spring 10 so that the rotating shaft 402 is then pulled to make the second driving gear 403 of another inner diameter mesh with the driven gear 401. This setting can be used to adjust the second driving gear 403 of different inner diameters to mesh with the driven gear 401.

[0032] Working principle: When the slice position of the diseased tissue needs to be adjusted:

[0033] First, the positioning of the lesion tissue by the positioning member is released, and then the first active gear 301 is rotated to drive the two transmission racks 302 to move horizontally in opposite directions. At this time, the push plate 304 can push the lesion tissue out, and the pathological tissue placement plate 303 can be retracted to avoid movement conflict with the pathological tissue placement plate 303 when the blade on the fixed blade holder 2 is slicing. This setting can adjust the slicing position of the lesion tissue without contact, avoiding contamination of the lesion tissue;

[0034] Meanwhile, the rotating shaft 402 can be used to drive the driven gear 401 to rotate. During the rotation of the driven gear 401, the first driving gear 301 can be driven to rotate. In the actual use process, different second driving gears 403 can be selected to mesh with the driven gear 401 according to the hardness and size of different pathological tissues, so as to conveniently control the force for pushing the pathological tissues.
