Description

technical field [0001] The invention relates to the technical field of medical automation, in particular to an automatic bone piercing device for medical use. Background technique [0002] Bone marrow aspiration is a common diagnostic technique for collecting bone marrow fluid. Clinically, bone marrow aspiration fluid is often used for blood cell morphology examination, and can also be used for hematopoietic stem cell culture, cytogenetic analysis, and pathogenic biology inspection to assist clinical diagnosis and observation. Curative effect and prognosis, etc., fix the bone marrow puncture needle fixer at an appropriate length (iliac crest puncture is about 1.5cm, obese people can be appropriately lengthened, sternal manubrium puncture is about 1.0cm), fix the skin at the puncture site with the thumb and index finger of the left hand, Hold the needle in the right hand and puncture vertically on the bone surface (if it is sternal manubrium puncture, the puncture needle shou...
