Background
In biological experiments, culture bottles or culture dishes are often used for cell culture. During culture, a small amount of culture solution is added into a culture dish or a culture bottle, cells are attached to the bottom of the culture dish to grow and proliferate, and the bottom of the culture dish is covered after the cells grow. When harvesting cells, since the cells are attached to the bottom of the culture dish, it is necessary to scrape the cultured cells from the bottom of the dish by an auxiliary instrument such as a cell scraper so that the cells are suspended in the culture solution, and to suck the culture solution and the cells by a suction tube for other operations. The process needs to scrape cells from the bottom of a culture bottle or a dish by using a cell scraper, the scraper can contact all surfaces of cell growth as far as possible, the collecting effect is also better, the operation has the effect of assisting physical membrane breaking, and the efficiency of extracting organelles, DNA, protein and the like is improved.
The current cell scraper consists of a scraper blade and a scraper rod, and the joint is connected by a shaft, so that the contact line of the scraper and the bottom of the dish can be in line contact instead of point contact. Under the condition of using the culture dish, opening a gap on the culture dish cover, and extending a scraper head into the culture dish cover for operation; under the condition of using the culture bottle, the culture bottle cap is opened, the scraper is stretched into the operation from the bottle opening, and a long rod is stretched into the operation and is scraped for half a day. The manual operation is inefficient, wastes time and labor, and evaporation loss and greater pollution risk are brought by longer operation time. In addition, the existing cell scraper is driven by the cutter handle to move in a single direction to scrape cells in a culture bottle, and the cell scraper can only be operated from a bottle opening, so that the angle change range is limited, and the limitation brings about longer scraping time. Another problem is the limited ability to assist in cell disruption, to what extent, to just an optional "aid" disruption.
