Abstract

The invention discloses a bone marrow cavity puncture drawing device used for the hematology department. The bone marrow cavity puncture drawing device comprises supporting legs, a protective box is connected to the top ends of the supporting legs, a main supporting shaft is arranged in the protective box, a rotating plate capable of rotating circumferentially along the main supporting shaft is arranged at the top end of the main supporting shaft, a large-angle adjusting plate is arranged at the tail end of the steering plate, a bone marrow sucking box is arranged in the middle of the top endof the large-angle adjusting plate, a small-angle adjusting plate is arranged on the exterior of the top end of the large-angle adjusting plate and provided with a puncture shaft capable of descendingspirally, an anti-blocking booster is arranged in the puncture shaft, and a puncture positioning disc is arranged at the bottom end of the small-angle adjusting plate; a bone marrow sucking head is placed in the protective box, and universal wheels are arranged at the bottom ends of the supporting legs. The bone marrow cavity puncture drawing device solves the problems that in the prior art, during bone marrow cavity puncture drawing, puncture positioning is inaccurate, the amount of puncture drawing is too high or low, the puncture needling angle and depth are difficult to master, and puncture drawing is operated mainly based on experience.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bone marrow trough puncture and extraction device for hematology. Background technique [0002] Bone marrow puncture is an essential method for diagnosing most leukemias. Bone marrow puncture usually chooses the posterior superior iliac spine or anterior superior iliac spine of the pelvis. The bony landmarks are clear in this part, and there are no large blood vessels or nerve trunks around it, so it is safe. If multiple punctures are unsatisfactory, sternal puncture is optional in a few cases, as long as the needle is inserted obliquely (at a 30°-45° angle to the sternum). The most common problem encountered in bone marrow puncture is "unsatisfactory material collection". The most common reason is that the puncture needle does not really enter the bone marrow cavity, and the extracted content is actually blood in the blood vessels of nearby tissues, or the content is extract...
