    • A follicular unit extraction device comprises a handpiece for holding a follicle punch at its distal end which extends from the handpiece and terminates distally in a cutting edge. The punch is releasably coupled to a motor-driven drive shaft within the handpiece for rotation therewith. A portion of the driveshaft is tubular, and houses a piston that can move towards and away from the punch. An ejector pin is also supported within the tubular portion of the driveshaft distally of the ejector piston and is positioned to move towards the cutting edge of the punch when pushed by the piston. The handpiece and driveshaft have respective fluid inlet ports. The clearance between the piston and driveshaft interior, and the clearance between the ejector pin and punch interior, define a fluid path for conducting fluid entering the handpiece and drive shaft via inlet ports so that the fluid exits the punch at its cutting edge. The clearances limit the quantity of fluid exiting the punch to the small amount needed to protect the follicle to be extracted. Means are provided for selectively increasing the flow rate of the fluid entering the handpiece beyond the limit imposed by said clearances to thereby increase the fluid pressure within the driveshaft, moving the piston distally and, consequently, moving the pin towards the cutting edge of the punch to eject impacted graft or debris. Bias means returns the piston proximally when the flow rate is reduced below the level required to overcome the bias means.
    • 滤泡单元提取装置包括用于在其远端处保持滤泡冲头的手持件,其从所述手持件延伸并终止于切削刃。 冲头可释放地联接到手持件内的电机驱动的驱动轴上,以与其一起转动。 驱动轴的一部分是管状的,并且容纳可朝向和远离冲头移动的活塞。 顶推销还被支撑在驱动轴的管状部分中,该驱动轴在顶出器活塞的远端处,并且被定位成当被活塞推动时朝向冲头的切割边缘移动。 手持件和驱动轴具有各自的流体入口。 活塞和驱动轴内部之间的间隙以及顶针和冲头内部之间的间隙限定了用于引导流体通过入口进入手持件和驱动轴的流体路径,使得流体在其切割边缘处离开冲头。 间隙将离开冲头的流体的数量限制在保护滤液提取所需的少量。 提供了用于选择性地增加进入机头的流体的流量超过由所述间隙施加的限制的装置,从而增加驱动轴内的流体压力,使活塞向远侧移动,并因此使销朝向冲头的切割边移动 排出受影响的移植物或碎屑。 当流量降低到克服偏压装置所需的水平以下时,偏压装置将活塞向近端返回。

    • A golf putter comprised of a shaft having an axis, a hosel attached to the shaft and a head attached to the hosel. The head of the putter has a face, a top and a sole. The face of the putter is comprised of multiple facets with a degree of static loft measured from the plane of the facet to the axis of the shaft. It is preferable that there are at least four facets on the face of the putter. The first facet is proximate to the sole of the face and has a first static loft angle. The second facet is above and abuts the first facet and has a second static loft angle which is greater than the first static loft angle. The third facet abutting and above the second facet has a third static loft angle which is greater than the second static loft angle. The fourth facet abuts and is above the third facet and has a fourth static loft angle which is greater than the third static loft angle. It is preferable that the static loft angles of said at least four facets differ by only 1 degree between abutting facets.
