The medical automatic bone puncture device is high in automation level, simple to operate, capable of achieving a bone marrow puncture functionand capable of effectively solving problems in the prior art.

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...

AI Technical Summary

Problems solved by technology

[0003] Traditional bone puncture needles require manual operation by medical staff, which not only reduces the efficiency of puncture, but also makes the puncture accuracy unable to be guaranteed, and the depth of puncture cannot be accurately controlled, which makes the automation performance of the bone puncture device poor
