Abstract
The utility model belongs to a medical device, which is a multi-functional puncture needle, comprising a needle tube and a needle core, the needle core is assembled in the needle tube, the top of the needle core is shaped as pinpoint and is extruded outside the needle tube, the top of the needle tube is shaped as annular zigzag, the inner diameter of the needle tube is sixteen millimeter to twenty millimeter. The improvement of the utility model is scientific and reasonable, which can not only extract bone marrow and blood, but also can extract living tissue for biopsy, and puncture success rate can be greatly improved. Therefore, the utility model has the advantages that the workload of the medical staff is reduced, the pain of the patients is reduced, clinical medical care effect is better and the utility model is easy for popularization and application.
Description
Technical field
This utility model relates to a kind of puncture needle of improved puncture bone marrow, belongs to medical apparatus.
Background technology
Puncture needle is used for the puncture of medical surgery bone, gets bone marrow fluid, is used for hemopathic diagnosis.Existing marrow puncture needle comprises syringe needle tube, nook closing member, nook closing member is fitted in the syringe needle tube, only the top outer rim of syringe needle tube is a blade, and the syringe needle tube internal diameter is less, is 12mm to the maximum, therefore can only get bone marrow fluid, can not get living tissue, and because bone marrow fluid is less, the bone marrow aspiration success rate is low, increase patient's pain, misery, strengthened medical worker's workload.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of multi-functional puncture needle is provided, can not only takes out bone marrow fluid, can also get living tissue, and improved puncture success rate greatly.
Multi-functional puncture needle described in the utility model comprises syringe needle tube, nook closing member, and nook closing member is fitted in the syringe needle tube, and its nook closing member top is tip-like and gives prominence to outside syringe needle tube, and the top of syringe needle tube is zigzag ringwise.
This utility model is used the nook closing member needle point instead, puncture easily, enter myeloid tissue after, extract nook closing member out, carry out bone marrow fluid and take out, rotate puncture needle again, the vertical band saw serrated knife of syringe needle tube can cut living tissue, does biopsy.In order to reduce to take out resistance, improve puncture success rate, the syringe needle tube internal diameter can be strengthened, be designed to 16-20mm and be advisable.
This utility model improves scientific and reasonable, can not only take out bone marrow fluid, can also get living tissue and do biopsy, and improve puncture success rate greatly, has reduced patient's pain, misery, has alleviated medical worker's workload, and clinical treatment is effective, is easy to apply.
