Abstract
The utility model discloses a ventil type marrow puncture needle, comprising a syringe, a syringe seat, a needle core, and a needle core seat. The syringe is fixedly connected to the syringe seat, and the needle core is fixedly connected to the needle core seat. The needle core is coaxially disposed in the syringe. The needle core seat is fixedly provided with a buckle device. The needle core seat is movably clamped with the syringe seat through the buckle device. The buckle device comprises a rotary cylinder and a positioning pin. Positioning pins are symmetrically disposed at two sides of the rotary cylinder, and the rotary cylinder is coaxially disposed with the needle core. The syringe seat is provided with a bayonet lock mouth matching with the positioning pin. The ventil type marrow puncture needle is advantageous in that the structure is simple; assembling between the syringe and the needle core is stable, and shedding can be prevented; the unloading of the needle core is convenient, pain for patients can be reduced, and work for medical personnel can be facilitated; needle cores in different structures can be selected based on different clinic demand, and thereby viable tissues in different lengths can be extracted.
