Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a multifunctional cell scraper. Background Technology

[0002] When sampling cells from the skin surface, a cell scraper is often required. Publication number CN209144173U discloses a multifunctional cell scraper for placental mesenchymal stem cell culture, comprising a cell scraper body. The cell scraper body has a handle and a blade. The handle has a gripping area and an extension area, and the blade has a connecting area and a working area. The working area has a serrated working surface and a flat working surface. The connecting area has a movable slot and a rotating head, which connects the connecting area of ​​the blade and the extension area of ​​the handle. This multifunctional cell scraper, utilizing multiple scraper heads, allows for rapid operation within culture flasks, reducing cell exposure time, simplifying procedures, and minimizing open manipulation. It is simple to operate, simplifies manual operation, saves time, and offers multiple functions. However, in practical use, both large blades are needed to scrape large areas of cells and small blades are needed to scrape small areas such as edges. This device only has one type of small blade and cannot be quickly switched, thus failing to meet actual cell scraping needs and requiring improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background section.

[0008] Preferably, the blade holder has a threaded groove inside, a lead screw passes through the inside of the blade holder, one end of the lead screw is fixedly connected to an adjustment knob, and a slide rod is fixedly connected to the inner surface of the blade holder. This allows the lead screw to rotate via the adjustment knob.

[0009] Preferably, the surface of the lead screw is threadedly connected to the threaded groove, and the surface of the slide bar is slidably connected to the groove of the tool holder. This allows the tool holder to extend and retract under the constraint of the slide bar by rotating the lead screw.

[0010] Preferably, the other end of the handle has a liquid-collecting tank inside, and a fixed cover is threaded onto the surface of the liquid-collecting tank. A piece of absorbent cotton is fixedly connected to the inner surface of the fixed cover. This allows liquid in the liquid-collecting tank to seep out through the absorbent cotton.

[0024] Example 1

[0025] Please see Figure 1-2This utility model provides a technical solution: a multifunctional cell scraper, including a handle 1, a blade holder 2 slidably connected to the inner side of the handle 1, a blade handle 3 fixedly installed inside the blade holder 2, a composite blade 4 fixedly connected to the side of the blade handle 3, allowing the composite blade 4 to rotate on the handle 1, an upper button 7 slidably connected to the inner groove of the blade holder 2, an upper pressure plate 8 fixedly connected to one end of the upper button 7, an upper locking post 9 fixedly installed to the side of the upper pressure plate 8, and an upper spring 10 fixedly connected to the side of the upper pressure plate 8, so that the upper button 7 moves the upper pressure plate 8, thereby moving the upper locking post 9 and the upper spring 10, and a lower button 6 slidably connected to the inner groove of the blade holder 2, a lower pressure plate 12 fixedly connected to one end of the lower button 6, a lower locking post 11 fixedly installed to the side of the lower pressure plate 12, and the lower pressure plate 12... A lower spring 13 is fixedly connected to the side, so that the lower button 6 moves the lower pressure plate 12, thereby moving the lower locking post 11 and the lower spring 13. A curved collection plate 14 is fixedly installed on the side of the blade holder 2, so that the cell tissue will be collected by the curved collection plate 14. The surface of the upper button 7 is slidably connected to the handle 1, and the surface of the lower button 6 is slidably connected to the handle 1, so that both the upper button 7 and the lower button 6 can slide on the handle 1. The other end of the upper spring 10 is fixedly connected to the blade holder 2, and the other end of the lower spring 13 is fixedly connected to the blade holder 2, so that the upper spring 10 and the lower spring 13 can be fixed on the blade holder 2. The surface of the upper locking post 9 is slidably connected to the handle 1, and the surface of the lower locking post 11 is slidably connected to the handle 1, so that the upper locking post 9 and the lower locking post 11 can fix the handle 1.

[0026] Example 2

[0027] Please see Figure 4 The inside of the handle 3 is provided with a threaded groove 5. The inside of the blade holder 2 is provided with a lead screw 17. One end of the lead screw 17 is fixedly connected to an adjustment knob 15. The inner surface of the blade holder 2 is fixedly connected to a slide rod 16, so that the lead screw 17 can be rotated by the adjustment knob 15. The surface of the lead screw 17 is threadedly connected to the threaded groove 5. The surface of the slide rod 16 is slidably connected to the groove of the handle 3, so that the handle 3 can be extended and retracted under the constraint of the slide rod 16 by rotating the lead screw 17.

[0028] Example 3

[0029] Please see Figure 4 The other end of the handle 1 has a liquid-holding tank 18 inside. A fixed cover 19 is threadedly connected to the surface of the liquid-holding tank 18. A degreased cotton block 20 is fixedly connected to the inner surface of the fixed cover 19, so that the liquid in the liquid-holding tank 18 can seep out through the degreased cotton block 20.

[0030] Working principle: When it is necessary to collect local cells or edge cells, press the up button 7 and the down button 6 on the handle 1. The up button 7 moves the upper pressure plate 8 of the blade holder 2, causing the upper locking post 9 to leave the groove of the handle 3. Rotate the handle 190 degrees clockwise so that the groove on the handle 1 is aligned with the lower locking post 11. Release the handle and the lower pressure plate 12 on the lower locking post 11 moves into the groove on the handle 1 under the action of the lower spring 13, so that the blade holder 2 is fixed. At this time, use the side of the composite blade 4 to scrape the cells so that the cells are collected on the curved collection plate 14. When it is necessary to collect cells over a large area, press the up button 7 and the down button 6 again and rotate counterclockwise so that the upper locking post 9 enters the groove of the handle 1. When the blade extension length needs to be adjusted according to the cell thickness, turn the adjustment knob 15. The adjustment knob 15 drives the lead screw 17 to rotate, causing the lead screw 17 to extend and retract the blade holder 2 under the constraint of the slide bar 16 until the expected length is reached. When it is necessary to collect cells from the skin, the skin needs to be disinfected first. You can first pour the disinfectant into the liquid tank 18, rotate the fixed cover 19, and then wipe the skin with a cotton pad. The disinfectant seeps out through the degreased cotton pad 20 to disinfect the skin.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
