Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a puncture device for bone marrow treatment in the hematology department. Background Art

[0002] Bone marrow puncture is a commonly used diagnostic technique to obtain bone marrow fluid. Its examination contents include cytology, protozoology and bacteriology. It is suitable for the diagnosis, differential diagnosis and treatment follow-up of various blood diseases; unexplained increase or decrease in the number of red blood cells, white blood cells and platelets and morphological abnormalities.

[0003] During insertion, medical staff usually hold the suction needle and perform suction after insertion. However, when holding the needle, the hand movement of the medical staff cannot move completely in one direction and is easily offset, causing the puncture point to shift. At the same time, when performing the suction action after puncture, the hand cannot be guaranteed not to make other movements. When the hand movement of the medical staff deviates too much, it is easy to cause the suction needle to move sideways, making the insertion wound larger and prolonging the patient's recovery time. Therefore, a device is urgently needed to solve the above problems. Utility Model Content
