    • An apparatus and method for forming retainers on a continuous strand such as, for example, of suture material and a suture produced by the same. The apparatus may include a retainer forming member configured to rotate about a first axis. The retainer forming member may include a cutter, the cutting edge of which may directed substantially inward toward, or outward away from, the first axis to define a retainer forming zone when the retainer forming member rotates about the first axis. The apparatus may further include a support member arranged adjacent to the retainer forming member and configured to receive and support the continuous strand in the retainer forming zone. When the retainer forming member rotates about the first axis, the passing strand may be intermittently or continuously cut by the cutting edge of the cutter.
    • 一种用于在连续股线上形成保持器的装置和方法,例如缝合材料和由其制成的缝合线。 该装置可以包括构造成围绕第一轴线旋转的保持器形成构件。 保持器形成构件可以包括切割器,其切割边缘可以朝着第一轴线或向外远离第一轴线指向,以在保持器形成构件围绕第一轴线旋转时限定保持器成形区域。 该装置还可以包括邻近保持器形成构件设置并构造成在保持器成形区域中接收和支撑连续线材的支撑构件。 当保持器形成构件围绕第一轴线旋转时,通过的线可以由切割器的切割边缘间歇地或连续地切割。

    • To reduce X-ray exposure, an area of interest is selected in the image. The image of the selected area is updated frequently, comparable to rate of updates used today for the whole image. The rest of the image is updated at a significantly lower rate. Since the area of interest normally is a small part of the overall area, the total exposure is reduced significantly. A movable X-ray shield placed near the X-ray source blocks the radiation from areas outside the area of interest. The shield automatically retracts when the complete image is updated. The area of interest can be selected by the user or automatically selected based on activity in the image.
    • 为了减少X射线曝光,图像中选择感兴趣区域。 所选区域的图像经常更新,与整个图像当前使用的更新速率相当。 图像的其余部分以显着较低的速率更新。 由于感兴趣的区域通常是整个区域的一小部分,因此总体暴露量显着降低。 放置在X射线源附近的可移动的X射线屏蔽物阻挡来自感兴趣区域外的区域的辐射。 完整的图像更新后,屏幕会自动缩回。 感兴趣区域可以由用户选择或根据图像中的活动自动选择。
