    • A safety syringe is disclosed and claimed. The safety syringe has a hollow barrel and a plunger. The plunger enters the barrel from one end and a needle leaves the barrel from the other end. A thin blunt sheath is positioned over the needle. The sheath has an exposed position in which the point of the needle is exposed and a covered position in which the point of the needle is covered. A connector functionally joins the sheath to the plunger so that the sheath is advanced from the exposed position to the covered position as the plunger is advanced. In operation, the safety syringe is filled like a conventional syringe by placing the needle in a vial of medication and drawing back on the plunger. Once the safety syringe is filled, the needle is inserted into the patient. The needle should be inserted a sufficient distance to insert the end of the sheath into the patient as well. The medication is then injected into the patient by depressing the plunger. Depressing the plunger will, as stated, advance the sheath from the exposed position to the covered position. Thus, the needle may be covered before it is removed from the patient.
    • 公开并要求保护安全注射器。 安全注射器具有中空筒体和柱塞。 柱塞从一端进入机筒,针从另一端离开机筒。 一根细钝的护套位于针上。 护套具有暴露位置,其中针的点被暴露,并且覆盖位置,其中针的点被覆盖。 连接器将护套功能性地连接到柱塞,使得当柱塞前进时,护套从暴露位置前进到覆盖位置。 在操作中,通过将针放置在一小瓶药物中并在柱塞上拉回来,安全注射器像常规注射器一样填充。 一旦安全注射器被充满,针就插入病人身上。 针头应插入足够的距离以将护套的一端插入病人身上。 然后通过按压柱塞将药物注入患者体内。 如上所述,按压柱塞将护套从暴露位置推进到覆盖位置。 因此,针可以在从患者移除之前被覆盖。

    • A modular implant for stabilizing the relative motion of spinal vertebrae comprises at least two pairs of plates which connect to two adjacent spinous processes, a spacer configured to be positioned between the spinous processes, and a fastener which pivotably connects to the plates and the spacer. The spacer is interchangeable and may comprise a variety of materials, each providing a different level of elasticity to the spinous processes. Relative motion between vertebrae can also be controlled by varying the surface configuration of the plates and by varying threading of the fastener. Several implants may be linked to provide stabilization across multiple vertebral levels, and the relative motion provided at each vertebral level may differ. A method for revising the implant is provided which comprises accessing the implant and replacing the spacer.
    • 用于稳定脊椎椎体的相对运动的模块化植入物包括连接到两个相邻棘突的至少两对板,被配置为定位在棘突之间的间隔件和可枢转地连接到板和间隔件的紧固件。 间隔物是可互换的并且可以包括各种各样的材料,每种材料提供与棘突不同的弹性水平。 椎骨之间的相对运动也可以通过改变板的表面形状和通过改变紧固件的螺纹来控制。 可以将多个植入物连接以提供跨多个椎骨水平的稳定性,并且在每个椎骨水平处提供的相对运动可以不同。 提供了修改植入物的方法,其包括进入植入物并且更换间隔物。

    • A screw, driving device, and method are provided for repairing a tissue injury of a patient, such as a meniscal tear in a knee or osteochondritis dissecans. The screw has a root, a distal section having a narrowing cross section toward the distal end, and a thread along at least a portion of the root between the proximal end and the distal end. Along a leading section extending from the distal end, the helical pitch is substantially constant; along a trailing section between the leading section and the root's proximal end, the helical pitch decreases. The substantially constant pitch along the leading section assists in preventing a stripping of the helical section. At the proximal end is a head having a diameter greater than a major root diameter of the central section. The head is for improving the tissue retention characteristics of the screw.
    • 提供螺钉,驱动装置和方法来修复患者的组织损伤,例如膝盖中的半月板撕裂或骨软骨炎。 螺杆具有根部,具有朝向远端的狭窄横截面的远侧部分,以及沿近端和远端之间的根部的至少一部分的螺纹。 沿着从远端延伸的引导部分,螺旋桨距基本上恒定; 沿着引导部分和根部的近端之间的尾部,螺旋节距减小。 沿着引导部分的基本恒定的螺距有助于防止螺旋部分的剥离。 在近端是具有大于中心部分的主根直径的直径的头部。 头部用于改善螺钉的组织保持特性。
