[0002] Common blood tumors mainly include various types of leukemia, multiple myeloma and malignant lymphoma. The incidence of multiple myeloma accounts for 10% of blood malignancies. Currently, surface tumor biopsy sampling can be successfully achieved through surgical incisions in clinical practice. However, since surgical incisions will cause great pain to patients, syringes are generally used for sampling.
[0003] However, the syringes currently on the market are generally fixedly connected because the syringe barrel and the needle are usually used in a fixed manner. When used on children, since children are more active, the needle may shake when the child is moving, which may cause harm to the child's body. Therefore, we propose a blood tumor specimen sampling device. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0019] Depend on Figure 1-Figure 3 The utility model comprises a needle tube 1, a needle cavity is provided on the side of the needle tube 1, a pull rod 2 is slidably inserted in the inner cavity of the needle cavity, one end of the pull rod 2 is located on the outside of the needle cavity, and the other end of the pull rod 2 is fixedly connected with a sealing gasket 3, the circumferential surface of the sealing gasket 3 fits with the inner wall of the needle cavity, a slot 4 is provided on the other side of the needle tube 1, an insertion rod 5 is inserted in the inner cavity of the slot 4, and a needle 6 is fixedly connected to the end of the insertion rod 5 located on the outside of the slot 4, the insertion rod 5 is connected with the needle cavity through a connecting hose 7, a slide groove 9 is provided on the top of the needle tube 1, and the inner cavity of the slide groove 9 is provided with a limiting mechanism capable of limiting the insertion rod 5.
[0020] At the same time, the limiting mechanism includes a limiting rod 10, a limiting plate 11 and a spring 12. The limiting rod 10 is slidably inserted in the slide groove 9, the limiting plate 11 is fixedly sleeved on the limiting rod 10, one end of the spring 12 is fixedly connected to the top of the limiting plate 11, and the other end of the spring 12 is fixedly connected to the top of the inner cavity of the slide groove 9. The limiting mechanism can limit the insertion rod 5 and can facilitate the insertion rod 5 to slide out of the slot 4.
[0021] In addition, the top of the insertion rod 5 is fixedly connected to a limit block 8, which is located on the inner side of the limit rod 10. There are two limit blocks 8, which are respectively located at the top and bottom of the insertion rod 5. The two limit blocks 8 can make the insertion rod 5 more stable in the slot 4.
[0022] Furthermore, there are two groups of limiting mechanisms, which are respectively located at the top and bottom of the needle tube 1 , and the two groups of limiting mechanisms are respectively arranged corresponding to the two limiting blocks 8 , and the two groups of limiting mechanisms can limit the two limiting blocks 8 .
[0023] Furthermore, there are two springs 12 in each set of limiting mechanisms. The two springs 12 are respectively fixedly connected to the two sides of the top of the limiting plate 11. The two springs 12 can make the limiting plate 11 more stable when sliding.
[0024] In addition, the connecting hose 7 is retractable, so that the needle 6 can be stably inserted into the child's body when sampling the child.
[0025] Working principle: When sampling a child, first pull the limit rod 10 upward, the limit rod 10 will drive the limit plate 11 to slide upward, and the limit plate 11 will squeeze the spring 12 when sliding upward. When the limit rod 10 is separated from the outer side of the limit block 8, due to the setting of the connecting hose 7, the insertion rod 5 can be taken out of the slot 4, and the insertion rod 5 will drive the connecting hose 7 to extend, and then release the limit rod 10, the spring 12 will rebound the limit plate 11 downward, and the limit plate 11 will drive the limit rod 10 to slide downward to restore After returning to the initial state, the needle 6 can be inserted into the child's body to take samples of the child's blood. When the child drives the needle 6 to move, the setting of the connecting hose 7 can avoid driving the needle tube 1 to move, thereby avoiding harm to the child's body. When the sampling is completed, the limit rod 10 can be pulled upward to insert the insertion rod 5 into the slot 4, and the limit rod 10 can be released and pulled. The spring 12 drives the limit rod 10 to slide downward through the limit plate 11, and the limit block 8 can be limited, thereby realizing the limitation of the insertion rod 5.
