Extensible structure and universal cancer organ in-vitro culture device

Abstract

The invention discloses medical equipment, and particularly relates to an extensible structure and a universal cancer organ in-vitro culture device. A mounting piece is slidably arranged on a guide rail, a residual gear is rotatably mounted on one side of the mounting piece, and rack plates cooperating with the residual gear are horizontally mounted on the side walls of a first point plate and a second point plate. The extensible structure further comprise a power assembly which is mounted on the mounting piece, a sample application assembly which is movably arranged on the mount piece and connected with the power assembly, and a sample supply assembly which is arranged on the mounting piece. When the residual gear rotates, a toothed part on the residual gear is discontinuously combined with the rack plate on the second point plate to drive the second point plate to discontinuously and horizontally move, an elastic structure drives the first point plate to be lifted to be flush with the second point plate, and the mounting piece drives the residual gear to discontinuously and horizontally move under the action of the guide rail; and a worm drives a worm wheel and the sample application assembly to move synchronously, the sample application assembly dropwise adds cancer cell matrix glue into dot pits formed in the dot plates in an array mode, and the cancer cell matrix glue is evenly dropwise added to the second dot plate and the first dot plate for culture.

Description

Technical field[0001]The present invention relates to a medical device, which is specifically an extensible structure and a generalized cancer type organ in vitro culture device.Background technique[0002]In recent years, in vitro cell culture technology has achieved rapid development, and now cell culture is not only a traditional planar culture mode, and the cells can be formed in vitro in vitro in vitro.[0003]The current organ culture technology mainly uses stem cells, induces stem cells into different types of cells within an organ in different types of cells, and forms the basic structure of organs. The cancer tissue sample was cut and digested, and the cancer cell obtained by digestion treatment was resuspended by a pre-cooled matrix gel, and the cancer cell suspension was taken, and the cancer cells after the point plate were carriedate. Culture treatment, eventually obtained cancer organs.[0004]Point plate processing is to add cancer cell matrix gel to the TLC board, and then...

Problems solved by technology

[0004] Spotting treatment is to drop the matrix gel of cancer cells onto the TLC plate in a matrix, and then culture them. Most of the existing spotting culture methods are manually operated. Since the success rate of culture is not 100%, multiple cultures need to be cultured. Larger TLC plates are required, and the stroke requirements of the equipment are higher if samples are spotted by the machine, so only a small amount of culture can be used, which is not conducive to simultaneous culture of multiple organs
