Abstract
The invention relates to the field of surgical instruments and provides a bone marrow puncture extracting needle for the department of surgery. The bone marrow puncture extracting needle comprises a needle body, a puncture needle core, an extracting needle core and a motor. When puncturing is performed, the puncture needle core is assembled in the needle body. When extraction is performed, the extracting needle core is assembled in the needle body. The tail end of the puncture needle core is connected with the motor in a matched mode. The motor drives the puncture needle core to perform puncturing. Bone marrow puncturing is easier and more convenient to perform. Meanwhile, the puncturing needle core is used for performing extraction in a negative pressure mode or the structure of the extraction needle core is changed, so that the success rate of bone marrow extraction is greatly improved.

Further, described bone marrow aspiration extracts pin and also comprises the extraction nook closing member, extracting the outer wall of nook closing member and the inwall of hollow needle body is complementary, can be fitted in the hollow needle body, described extraction nook closing member comprises that the extraction nook closing member is outer and extracts the nook closing member internal layer, within described extraction nook closing member internal layer is assemblied in described extraction nook closing member skin, the needle point of described extraction nook closing member internal layer adopts conical design, with the end of described extraction nook closing member internal layer, all protrude from outside described extraction nook closing member skin, end by the described extraction nook closing member of pull internal layer, make the needle point of described extraction nook closing member internal layer place within described extraction nook closing member skin.
Further, the needle point of described extraction nook closing member internal layer is made by elastomeric material.
Further, between the main body of the needle point of described extraction nook closing member internal layer and described extraction nook closing member internal layer, be connected by elastomeric element.
Further, described extraction nook closing member internal layer comprises the needle point eaves, and described needle point eaves is positioned at the edge of described needle point, internally perpendicular to described needle point.
Further, linearly type or circular arc type of the needle point of described extraction nook closing member internal layer.
(3) beneficial effect
The present invention, by increasing motor, implements puncture by motor control puncture nook closing member, makes the wound surface in piercing process more neat, has reduced the misery of sufferer; By increasing thrust brake, make puncture procedure easier; Adopt the puncture nook closing member to carry out the negative pressure mode extraction or changed the structure that extracts nook closing member, the success rate that makes bone marrow extract greatly improves.
The accompanying drawing explanation
Fig. 1 is needle body profile in the present invention.
Fig. 2 is puncture nook closing member profile in the present invention.
Fig. 3 extracts the first embodiment of the internal layer profile of nook closing member in the present invention.
Fig. 4 extracts the second embodiment of the internal layer profile of nook closing member in the present invention.
In figure: 1: the hollow needle body; 2: the puncture nook closing member; 21: the needle point of puncture nook closing member; 31: the internal layer that extracts nook closing member; 311: the end that extracts the nook closing member internal layer; 312: the needle point that extracts the nook closing member internal layer; 313: the main body that extracts the nook closing member internal layer; 314: the needle point eaves that extracts the nook closing member internal layer.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills obtain under the prerequisite of not making creative work every other embodiment, belong to the scope of protection of the invention.
Bone marrow aspiration of the present invention extracts pin, comprises hollow needle body 1, puncture nook closing member 2, and the outer wall of puncture nook closing member 2 and the inwall of hollow needle body 1 are complementary, and can be fitted in the hollow needle body, it is characterized in that: also comprise motor, described motor drives puncture nook closing member 2 and implements puncture.
Further, also comprise thrust brake, described thrust brake is for regulating the puncture distance of puncture nook closing member, and described thrust brake can make thrust bearing or limit valve.
Further, described puncture nook closing member is ducted body, the cutting tip edge indentation of puncture nook closing member.
Further, also comprise depression generator, described depression generator is connected with the puncture nook closing member, makes the puncture needle in-core form negative pressure, can make by the mode that connects vacuum bag at described puncture nook closing member end the puncture needle in-core form negative pressure.
Fig. 3, Fig. 4 are for the improved two kinds of embodiments that extract nook closing member.Wherein, extracting nook closing member comprises that further the extraction nook closing member is outer and extracts nook closing member internal layer 31, within described extraction nook closing member internal layer 31 is assemblied in 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 employing conical design, the angle that wherein extracts the tip portion 312 of nook closing member internal layer and extract between the main body 313 of nook closing member internal layer can be set to 135～150 degree, with the end 311 of described extraction nook closing member internal layer, all protrude from outside described extraction nook closing member skin, end 311 by the described extraction nook closing member of pull internal layer, make the needle point 312 of described extraction nook closing member internal layer place 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, the success rate while making bone marrow extract greatly improves.
