Gynecological tumor sampler capable of sucking body fluid and sample step by step

The utility model discloses a gynecological tumor sampler capable of sucking body fluid and samples step by step, and relates to the technical field of medical equipment. The blood sampling tube comprises an outer tube and an inner tube, the inner tube is located in the outer tube, a body fluid channel is arranged between the inner tube and the outer tube, a body fluid suction hole is formed in the bottom of the outer tube and communicated with the body fluid channel, and a needle head used for sampling is arranged at the bottom of the inner tube. According to the tumor sampling tube, body fluid near a tumor can be sucked through the outer tube before sampling, and then the inner tube is moved, so that the tumor is sampled through the inner tube. The situation that body fluid instead of a sample is sucked during sampling is effectively avoided, the sampling success rate is greatly increased, and repeated sampling after sampling fails is avoided. 本实用新型公开了一种分步吸取体液与样本的妇科肿瘤取样器，涉及医疗设备技术领域。本实用新型包括外管和内管，所述内管位于外管内部且所
