【摘要】The utility model belongs to the field of medical apparatuses, in particular to a lumbar puncture needle in clinical lumbar puncture. The lumber puncture needle comprises a needle tube, a needle seat and a lining core, wherein a branch tube is arranged on the needle seat close to the needle tube, and is communicated with the needle tube, the tail end of the branch tube is connected with an elongated tube and a rubber connecting portion, the top end of the rubber connecting portion is sealed by a rotary cap, and a sliding card is sleeved on the elongated tube for clamping and closing the elongated tube and controlling the flow direction of cerebrospinal fluid. When in use, a measuring tube is connected with the rubber connecting portion of the branch tube, and a needle core is pulled out to a position of the needle seat close to a needle head, thereby measuring pressure. The lumber puncture needle is more convenient for replacement of cerebrospinal fluid and the operation of intrathecal injection, can be simultaneously operated along with the pressure measurement, avoids losing cerebrospinal fluid, and has simple structure, available preparation material and lower construction cost.
