Description

Technical Field

[0001] The utility model relates to the technical field of slicers, in particular to a slicer. Background Art

[0002] Pathological sectioning is to take a certain amount of diseased tissue from the diseased tissue or organ, and then fix and harden the diseased tissue into a block through various chemical and embedding methods. The common treatment method is to embed the pathological tissue in a paraffin block and then freeze it. After freezing, a paraffin block containing the pathological tissue is obtained. The paraffin block is then sliced through a microtome, and then pathological sections are made through pathological histological methods. The lesions are further examined under a microscope, and finally a pathological diagnosis is made.

[0003] The microtome is a paraffin-embedded pathology block that is installed in a clamping device on the microtome. The handle is then turned to drive the transmission device inside the microtome to drive the clamping device to move up and down. During the movement, the paraffin block is continuously sliced by the slicing assembly set at the front end of the microtome, and finally a pathological tissue slice is obtained.

[0004] The existing cutting machine is usually placed directly on the workbench when in use, and the slicer is supported by the built-in feet at the bottom of the slicer, but the built-in feet cannot be adjusted, which results in that if an uneven working surface is encountered, the mechanical structure inside the slicer will be unstable during operation, and ultimately the thickness of the slices produced will not meet the standards.

Detailed Embodiments

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0029] Embodiment 1

[0030] Refer to Figure 1 , Figure 2 And Figure 3, which is the first embodiment of the present utility model. This embodiment provides a slicing machine, including a machine case 1. Inside the machine case 1, a transmission device 7 is arranged. On one side of the transmission device 7, a clamping device 2 is arranged. On one side of the machine case 1 close to the clamping device 2, a cutting device 3 is arranged. On the lower surface of the machine case 1, four support components 5 are arranged. On the outer surface of the cutting device 3, a cleaning component 8 is arranged. The support component 5 includes a connecting seat 504 fixedly connected to the lower surface of the machine case 1. Inside the connecting seat 504, a lifting rod 501 is inserted. At the bottom end of the lifting rod 501, a support foot 505 is fixedly connected. On the outer surface of the lifting rod 501, a rotating gear 502 is meshed. Inside the rotating gear 502, a rotating rod 503 is inserted. On the outer surface of the machine case 1, a limiting block 506 is fixedly connected. Inside the limiting block 506, a pin 509 is inserted.

[0031] Specifically, at the top end of the pin 509, a connecting disc 508 is fixedly connected. On the outer surface of the pin 509, a spring 507 is sleeved. The top end of the spring 507 is fixedly connected to the lower surface of the connecting disc 508, and the bottom end of the spring 507 is fixedly connected to the outer surface of the limiting block 506. On the outer surface of the rotating rod 503, a jack corresponding to the pin 509 is opened. The bottom end of the pin 509 passes through the limiting block 506 and cooperates with the jack. Inside the rotating rod 503, a circular groove is opened. The diameter of the circular groove is larger than the diameter of the pin 509. Inside the circular groove, a through hole is opened. The pin 509 passes through the through hole and cooperates with the jack on the outer surface of the rotating rod 503. The bottom end of the spring 507 is fixedly connected to the inner wall of the circular groove. The transmission device 7, the clamping device 2, and the cutting device 3 all belong to the prior art and are common knowledge that can be obtained and known by those skilled in the art, so no more details will be described here.

[0032] Further, after placing the slicing machine on the workbench, use a level or other tools to detect the slicing machine to determine whether it is level. If it is not level, adjust the support component 5 in the corresponding inclined direction for leveling. First, pull the connecting disc 508 to drive the pin 509 to disengage from the jack on the outer surface of the rotating rod 503, and then rotate the rotating rod 503. Drive the lifting rod 501 to lift through the rotating gear 502. The lifting rod 501 drives the support foot 505 at the bottom end to extend, so as to support the inclined side of the slicing machine. Then release the connecting disc 508. The connecting disc 508 drives the pin 509 to insert into the jack on the outer surface of the rotating rod 503 under the action of the spring 507, so as to lock the rotating rod 503.

[0033] Embodiment 2

[0034] Refer to Figure 1 、 Figure 4 、 Figure 5 And Figure 6, which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The cleaning component 8 includes a rack 801 fixedly connected to the outer surface of the cutting device 3. Two connecting rings 803 are slidably connected to the outer surface of the rack 801. A sliding block 802 is fixedly connected to the outer surface of the connecting ring 803. A driven gear 807 is arranged inside the sliding block 802. A rotating shaft 806 is inserted through the inside of the driven gear 807. An installation cylinder 805 is movably connected to the outer surface of the rotating shaft 806. A brush 804 is fixedly connected to the outer surface of the installation cylinder 805.

[0035] Specifically, a card slot is provided on the outer surface of the rack 801. A clamping block corresponding to the card slot is arranged on the inner wall of the connecting ring 803. A card strip is provided on the outer surface of the rotating shaft 806. A limiting groove matched with the card strip is arranged on the inner wall of the installation cylinder 805. A locking cover 808 is threadedly connected to the top end of the rotating shaft 806. A dust collecting tray 4 for collecting debris is arranged on the outer surface of the cutting device 3. A rotating disk 6 for driving the transmission device 7 is arranged on the outer surface of the chassis 1.

[0036] Furthermore, before slicing, by moving the sliding block 802, the driven gear 807 rotates under the action of the rack 801. The rotating shaft 806 is driven to rotate by the driven gear 807. The installation cylinder 805 and the brush 804 on the outer surface of the installation cylinder 805 are driven to rotate by the rotating shaft 806, so as to clean the outer surface of the cutting device 3 through the brush 804. When the brush 804 needs to be replaced, the locking cover 808 can be screwed, and then the installation cylinder 805 is pulled out, so as to replace the new installation cylinder 805 and the brush 804. The impurities and debris cleaned are dropped into the dust collecting tray 4. During the slicing process, by rotating the rotating disk 6, the clamping device 2 is driven to move up and down reciprocally through the transmission device 7. When the clamping device 2 moves reciprocally, the embedded paraffin block with pathology clamped is driven to pass through the cutting device 3 for cutting. And after the installation cylinder 805 and the brush 804 move to one side along with the sliding block 802, they will not affect the slicing work of the cutting device 3 and the clamping device 2. Through the cooperation of the card slot on the outer surface of the rack 801 and the clamping block on the inner wall of the connecting ring 803, the sliding block 802 can slide on the outer surface of the rack 801 but cannot rotate. Through the arrangement of the card strip on the outer surface of the rotating shaft 806 and the limiting groove on the inner wall of the installation cylinder 805, when replacing the brush 804, the new installation cylinder 805 only needs to be inserted into the rotating shaft 806 through the limiting groove. And through the arrangement of the card strip and the limiting groove, the rotating shaft 806 can drive the installation cylinder 805 and the brush 804 to rotate. The connection relationship, working principle and working process among the clamping device 2, the transmission device 7 and the cutting device 3 and other components belong to the prior art and are common knowledge well-known to those skilled in the art, and will not be introduced in detail here.

[0037] Working principle: When performing pathological sectioning using a microtome, first use tools such as a spirit level to determine whether the microtome is level. If it is not level, adjust the leveling by adjusting the support assembly 5 in the corresponding tilting direction. First, pull the connecting plate 508 to drive the pin 509 out of the jack on the outer surface of the rotating rod 503, and then rotate the rotating rod 503. Drive the lifting rod 501 to lift and lower by rotating the gear 502. The lifting rod 501 drives the support feet 505 at the bottom to extend, thus propping up the tilted side of the microtome. Then release the connecting plate 508. The connecting plate 508 drives the pin 509 to insert into the jack on the outer surface of the rotating rod 503 under the action of the spring 507, thus locking the rotating rod 503. Perform the same above operations on the four support assemblies 5 respectively. Determine whether it is level according to the spirit level. After one-time leveling, subsequent sectioning does not require leveling by the spirit level and adjusting the support assembly 5 before each sectioning. Then move the sliding block 802 so that the driven gear 807 rotates under the action of the rack 801. Drive the rotating shaft 806 to rotate through the driven gear 807. Drive the mounting cylinder 805 and the brush 804 on the outer surface of the mounting cylinder 805 to rotate through the rotating shaft 806, so as to clean the outer surface of the cutting device 3 through the brush 804. After the cleaning is completed, place the paraffin block embedded with the pathology on the clamping device 2, and then rotate the rotating disk 6 to drive the clamping device 2 to move up and down reciprocally through the transmission device 7, so that the paraffin block comes into contact with the cutting device 3, and finally complete the pathological sectioning.
