The solid needle core is then pulled out, and the end of the hollow outer needle is connected to a syringe to extract bone marrow through the syringe.

[0003] In actual operation, a professional doctor currently asks the patient to lie on his side on the examination bed, then bends his back, and the doctor gropes to insert the needle. During the actual insertion process, since the entire needle is very long, the doctor needs to hold the end of the needle with one hand, and use the other hand to guide the needle into the body while supporting the entire long needle. This is inconvenient and requires very high technical skills of the doctor. Moreover, after the puncture, the doctor lacks fixation of the end of the bone needle when withdrawing the needle core and installing the syringe. Touching and shaking the end of the bone needle will transmit to the front end, which can easily cause the patient to feel a strong tingling sensation. For this reason, a bone needle puncture auxiliary device is provided to solve the above problems. Utility Model Content
