Description
The technical field is as follows:
the utility model relates to an experimental apparatus technical field, concretely relates to retractable cell scraper.
Background art:
cell culture is carried out to the culture dish that often can need to use in the biomedical experiment, when the cell is cultivateed in the results, need scrape the cell in the culture dish with the help of auxiliary instrument such as cell scraper and get, but current scraper mostly belongs to fixed knot and constructs, and the function is single, and the size and the angle of scraper can not be adjusted, cause the size of scraper to be single all the time, and it is inconvenient to use, causes work efficiency to descend. Patent No. ZL 201720412604.6's patent passes through the design of mount pad, rotating disc and installation blade holder, can install not unidimensional scraper, and can carry out the angle of rotation regulation scraper, and the connection structure of mount pad and right telescopic link makes the convenient dismantlement of mount pad, through the design of flexible handle of a knife for the length of scraper handle of a knife can be adjusted according to actual need. But this kind of cell scraper need change the not unidimensional scraper of installation according to the size of culture dish, and because the cross-section of most culture dishes is circular, fixed size's scraper can not laminate with the inner wall of culture dish well, makes when being difficult to realize scraping the cell and scrapes the cross-section that once only covers whole culture dish of face, causes scraping of cell sample to get incompletely easily, influences experimental efficiency.
The utility model has the following contents:
technical problem to be solved
The utility model aims at providing a retractable cell scraper for cell in the cell culture dish is scraped and is got, solves prior art and is difficult to realize scraping and makes when getting the cell scrape the cross-section of getting the face and once only covering whole culture dish, causes scraping of cell sample easily and gets incomplete, influences the problem of experimental efficiency.
The technical scheme is as follows:
in order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a retractable cell scraper, includes handle of a knife and fixed cutter arbor, the handle of a knife with fixed cutter arbor is T type connection, the symmetry is equipped with two spouts, every in the fixed cutter arbor all be equipped with the slider in the spout, the one end of slider is equipped with flexible cutter arbor, the other end of slider pass through compression spring with the interior wall connection of spout, be equipped with flexible cutting edge on the lateral wall of flexible cutter arbor, be equipped with the cutting edge groove on the lateral wall of fixed cutter arbor.
The handle of a knife is used for control fixed cutter arbor, flexible cutter arbor telescopically set up in the both ends of fixed cutter arbor, the slider can slide in the spout, flexible cutting edge passes the cutting edge groove is scraped when getting to the cell in the cell culture dish, the top of flexible cutter arbor is in under compression spring's the spring action, withstands the inner wall of cell culture dish, fixed cutter arbor with the cell in the cell culture dish is scraped to the cooperation of flexible cutter arbor is got, because flexible cutter arbor is telescopically, the top of flexible cutter arbor is laminated with the inner wall of cell culture dish all the time, the laminating of flexible cutting edge and cell culture dish's bottom to scrape the cross-section that once only covers whole culture dish of getting when the cell is scraped in the realization, guarantee the integrality of cell sample, effectively improve experimental efficiency.
Further, the top of flexible cutter arbor is equipped with the gyro wheel, the gyro wheel rolls on the inner wall of cell culture dish, prevents flexible cutter arbor takes place the jamming when removing, guarantees the smooth and easy nature when the cell is scraped and is got.
Further, be equipped with fixed cutting edge on the outer wall of fixed cutter arbor, fixed cutting edge with flexible cutting edge cooperation is scraped the cell and is got, makes to scrape and gets the effect more thoroughly.
Further, the top of flexible cutting edge with the top of fixed cutting edge aligns, guarantees the fixed cutting edge with scraping when flexible cutting edge carries out the cell and scrapes gets the face level and smooth, improves the homogeneity of cell sample.
(III) the beneficial effects are as follows:
compared with the prior art, the utility model discloses the beneficial effect who produces is: through setting up fixed cutter arbor on the handle of a knife, the both ends symmetry of fixed cutter arbor sets up the flexible cutter arbor of telescopic, sets up flexible cutting edge on the flexible cutter arbor, sets up the cutting edge groove that supplies flexible cutting edge to pass on the lateral wall of fixed cutter arbor, can scrape the cell to the cell culture dish in and get the time, keep scraping the cross-section that once only covers whole culture dish of getting the face, guarantee the integrality of cell sample, effectively improve the experimental efficiency.
Description of the drawings:
in order to more clearly illustrate the technical solution in the embodiments of the present invention, the drawings required to be used in the embodiments will be briefly described below.
FIG. 1 is a front cross-sectional view of a retractable cell scraper according to an embodiment of the present invention;
