An acupuncture suction device for respiratory tract neoplasm, comprising a pneumatic bag (1). A filth outlet (2) is fixedly connected to the inner wall of the pneumatic bag (1)； a sealing plug (3) is threadedly connected to the inner wall of the filth outlet (2)； the inner top wall of the pneumatic bag (1) is fixedly connected to an air outlet tube (4)； an upper sealing device is provided on the inner wall of the air outlet tube (4)； the upper sealing device comprises an upper spring (41)； the top free end of the upper spring (41) is fixedly connected to the inner top wall of the air outlet tube (4)； and the bottom free end of the upper spring (41) is fixedly connected to an upper sealing ball (42). According to the acupuncture suction device for respiratory tract neoplasm, a tumor in a respiratory tract can be punctured and sucked out by means of negative pressure； a puncture needle (7) is extended to the position of the tumor inside the respiratory tract by means of a guide tube (6)； and when the puncture needle (7) punctures the tumor, the pneumatic bag (1) is pressed to enable air in the pneumatic bag (1) is pushed out of the pneumatic bag (1) by means of the upper sealing device, and then the pneumatic bag (1) is released, so that the pressure in the pneumatic bag (1) decreases, and thus the substance in the tumor is sucked into the pneumatic bag (1) by means of a lower sealing device. The present acupuncture suction device can be operated conveniently and fast.L'invention concerne un dispositif d'aspiration pour ponction des néoplasmes des voies respiratoire, comprenant une poche gonflable (1).
