The invention relates to a catcher for blood vessel glue taking and a catching assembly. The catcher comprises an air pipe and an umbrella-shaped suction port which can retract into a corresponding micro-pipe through electricity and be spread after being removed from the micro-pipe, the small opening end of the umbrella-shaped suction port is connected with the air pipe, a cavity of the umbrella-shaped suction port is communicated with the air pipe, and the big opening end of the umbrella-shaped suction port is provided with a sealing lip used for being matched with the end of embolism glue in a sealed mode. After the catcher is conveyed to the specific location, the umbrella-shaped suction port stretches out from the far end of the micro-pipe, under the elastic action of the umbrella-shaped suction port, the umbrella-shaped suction port is spread, it is guaranteed that the big opening end of the umbrella-shaped suction port and the end of the embolism glue have enough adsorption sizes, connection force of the umbrella-shaped suction port and the embolism glue is achieved by introducing negative pressure to the other end of the air pipe, the embolism glue can be taken out by pulling out the catcher, and the embolism problem caused by the fact that the embolism glue blocks a normal blood vessel is avoided.
