In figure: 1: hollow needle body; 2: puncture needle core; 21: the needle point of puncture needle core; 31: the internal layer extracting nook closing member; 311: the end extracting nook closing member internal layer; 312: the needle point extracting nook closing member internal layer; 313: the main body extracting nook closing member internal layer; 314: the needle point eaves extracting nook closing member internal layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Bone marrow aspiration of the present invention extracts pin, and comprise hollow needle body 1, puncture needle core 2, the outer wall of puncture needle core 2 and the inwall of hollow needle body 1 match, and can be fitted in hollow needle body, it is characterized in that: also comprise motor, and described motor drives puncture needle core 2 to implement puncture.
Further, also comprise thrust brake, described thrust brake is for regulating the puncture distance of puncture needle core, and described thrust brake can make thrust bearing or limit valve.
Further, described puncture needle core is ducted body, the cutting tip edge indentation of puncture needle core.
Further, also comprise depression generator, described depression generator is connected with puncture needle core, makes to form negative pressure in puncture needle core, can be made by the mode connecting vacuum bag at described puncture needle core end to form negative pressure in puncture needle core.
Fig. 3, Fig. 4 are two kinds of embodiments for the improvement extracting nook closing member.Wherein, extract nook closing member comprise extraction nook closing member skin further and extract nook closing member internal layer 31, described extraction nook closing member internal layer 31 is assemblied within described extraction nook closing member skin, the needle point 312 of described extraction nook closing member internal layer is divided into 3 lobes or more lobes, and adopt conical design, wherein the angle extracted between the tip portion 312 of nook closing member internal layer and the main body 313 extracting nook closing member internal layer can be set to 135 ~ 150 degree, all protrude from outside described extraction nook closing member skin with the end 311 of described extraction nook closing member internal layer, by extracting the end 311 of nook closing member internal layer described in pull, the needle point 312 of described extraction nook closing member internal layer is made to be placed within described extraction nook closing member skin, described extraction nook closing member internal layer comprises needle point eaves 314, described needle point eaves 314 is positioned at the edge of described needle point 312, internally perpendicular to described needle point 312.Adopt this structure can overcome the anaclisis of bone marrow, success rate during bone marrow aspiration is greatly improved.
