How to use a bone marrow puncture needle

Bone marrow aspiration needle is a specialized tool for bone marrow aspiration. It consists of a needle bolt and a needle core. In addition, there are screws on the outside of the needle bolt. By rotating the screws, the length of the puncture needle can be adjusted. When using a bone marrow puncture needle, first adjust the length of the puncture needle according to the degree of fatness and thinness of the patient. The puncture needle should be longer for people with more subcutaneous fat, and the puncture needle should be shorter for people with less subcutaneous fat. In addition, the needle core and the needle plug should be tightly combined, and there should be no space at the needle tip, so as to avoid bone debris from blocking the puncture needle during puncture. At the same time, brute force should not be used during the puncture to avoid the puncture needle from breaking, and the puncture needle should not be broken.
