    • An apparatus and method for introducing material into an injection site of a patient is disclosed. The device includes a cannula (30) and a carrier (20). The cannula is inserted into an injection site of a patient. The carrier is connected to an injector containing a volume of material. Material may be pre-loaded into the carrier so that the material is delivered to a distal end of the carrier from the injector and the carrier is thus pre-loaded with material. A portion of the distal end of the preloaded carrier is inserted into the cannula and material is delivered to an injection site. The carrier comprises a supply section (120) operable to receive curable material, and an inner section (140) proximal to the patient. The supply section can be rotatable with respect to the longitudinal axis of the inner section, or the inner surface of the inner section may be smooth.
    • 公开了一种用于将材料引入患者的注射部位的装置和方法。 该装置包括套管(30)和载体(20)。 套管插入患者的注射部位。 载体连接到含有一定体积材料的注射器。 材料可以预加载到载体中,使得材料从喷射器输送到载体的远端,并且载体因此预先装载材料。 预载载体的远端的一部分插入插管中,并将材料输送到注射部位。 载体包括可操作以接收可固化材料的供应部分(120)和靠近患者的内部部分(140)。 供应部分可以相对于内部部分的纵向轴线旋转,或者内部部分的内表面可以是平滑的。

    • The invention disclosed herein relates to a sampling cannula (10) for use in bone marrow biopsy procedures having structural features which facilitate sample retention within the device. In particular, the sampling cannula (10) comprises an open trough-like portion (13), wherein the trough-like portion (13) comprises at least one wall opening (16) located proximal to the distal end in combination with an interior surface (14) comprising a friction-enhancing surface texture (adapted to facilitate sample retention. The invention further provides for a bone marrow biopsy system comprising an outer cannula having a sharpened distal tip (15), a sampling cannula having a distal trough portion (13) in which the interior surface of the sampling cannula (14) is exposed, at least one wall opening located within the tough portion (13) located proximal to the distal tip of the sampling cannula, a friction-enhancing surface texture on at least a portion of the interior surface of the trough portion, wherein the sampling cannula is adapted to be inserted into an outer cannula (20), and to server a sample from the sampling site by rotational motion of the sampling cannula, and a stylet (30) structured to be removably inserted into the outer cannula (20). The bone biopsy system can further include and ejector rod for expelling the retained sample from the sampling cannula.
    • 本文公开的本发明涉及一种用于骨髓活检程序的采样套管(10),其具有便于在装置内保留样品的结构特征。 特别地,采样套管(10)包括开放的槽状部分(13),其中,槽状部分(13)包括至少一个位于远端附近的壁开口(16),其与内表面 (14)包括摩擦增强表面纹理(适于促进样品保留。本发明还提供了一种骨髓活检系统,其包括具有锐化的远端尖端(15)的外套管,采样套管具有远端谷部分(13) ),其中所述采样插管(14)的内表面被暴露,位于所述韧性部分(13)内的位于所述采样插管的远侧末端附近的至少一个壁开口,至少一个 所述槽部分的内表面的一部分,其中所述采样套管适于插入到外套管(20)中,并且通过所述采样套管的旋转运动来服务来自所述采样部位的样品,并且所述样式 (30)构造成可移除地插入到外套管(20)中。 骨活组织检查系统还可以包括用于从取样套管排出保留的样品的排出杆。
