The invention relates to the technical field of medical instruments, in particular to a ball pricking needle for uniform injection in tumors, which comprises a puncture part and a handheld part, the handheld part comprises an upper tube body, a lower tube body and a connecting arm connected between the upper tube body and the lower tube body; the puncture part comprises an outer tube, a core needle movably inserted into the outer tube and a puncture needle assembly connected between the outer tube and the core needle, the core needle is in threaded connection with a nut and sleeved with a sealing ring, the nut is rotationally connected between the upper tube body and the lower tube body and located on the inner side of the connecting arm, and the sealing ring is sleeved with the nut. The sealing ring is in sealing contact with the inner wall of the outer pipe, the upper end of the outer pipe is connected with the lower end of the lower pipe body, and the axis of the outer pipe coincides with the axis of the upper pipe body and the axis of the lower pipe body. One-time puncture and multi-point injection in a tumor can be achieved more easily, liquid medicine can be prevented from flowing out in the injection process, organs around the tumor are not prone to being damaged in the injection process, and use is safer.

This invention discloses an inhalation device and application for anti-cancer and cancer-suppressing traditional Chinese medicine, belonging to the technical field of inhalation devices for traditional Chinese medicine. It includes a telescopic corrugated cylinder and an adaptive stirring assembly. The telescopic corrugated cylinder has multiple telescopic sleeves inside, and the adaptive stirring assembly includes a motor box threadedly connected to the bottom of the telescopic corrugated cylinder. This anti-cancer and cancer-suppressing traditional Chinese medicine inhalation device and application flexibly adjusts the internal space of the device according to the actual volume of the traditional Chinese medicine powder. This effectively avoids wasting space within the container and significantly reduces the overall size of the device by compressing the telescopic corrugated cylinder, improving portability and making it more suitable for daily use. The adaptive stirring assembly can adjust its structure synchronously with the telescopic corrugated cylinder's extension and retraction, always matching the internal space of the container to ensure comprehensive stirring of the powder. This allows the medicinal aroma to be evenly distributed and fully volatilized, eliminating the need for frequent manual shaking of the container. This ensures more even administration of the traditional Chinese medicine aroma, guarantees the therapeutic effect of inhalation, and significantly optimizes the user's operating experience.
