    • A percussion tool for surgical instruments comprises a sleeve-shaped handle, a tool holder which can slide longitudinally in the handle, and a driven piston which oscillates longitudinally in the handle. The piston has two impact faces which impinge on corresponding contact faces on the tool holder to which they impart impulses in opposite directions. In order to selectively produce impulses in the direction of percussion and in the direction of withdrawal without resetting the tool, the actual piston stroke in the handle is limited so that it is less than the double impact stroke which the piston would have to travel from impact of the first impact face on the first contact face until impact of the second impact face with the second contact face if the tool holder were fixed in the handle. The tool holder also moves in the handle relative to both the handle and the piston.
    • 用于外科器械的冲击工具包括套筒形手柄,可在手柄中纵向滑动的工具保持器和在手柄中纵向摆动的从动活塞。 该活塞具有两个撞击面,该冲击面撞击工具架上相应的接触面,它们在相反方向上施加脉冲。 为了选择性地在冲击方向上产生冲击并且在退回的方向上而不使工具复位,手柄中的实际活塞行程被限制,使得其小于活塞将不得不从冲击行进的双重冲击行程 如果工具架固定在手柄中,则第一冲击面在第一接触面上直到第二冲击面与第二接触面的冲击。 工具架也相对于手柄和活塞在手柄中移动。

    • A hydraulically operated low noise hammer, comprising an operating pedal (21) allowing pressure oil to flow in when depressed to turn on and to shut off when released to turn off and a mechanism allowing a chisel part (10) of a hammering piston (1) to be stored in a hammer body (7) when the operating pedal (21) is released to turn off, wherein the hammering piston (1) installed slidably in the hammer body (7) is raised or lowered by switching the hydraulic pressure to directly hammer a crushed object by the chisel part (10) of the hammering piston (1).
    • 一种液压操作的低噪音锤,包括操作踏板(21),当操作踏板(21)被压下打开时允许压力油流入并在释放时关闭,并且允许锤击活塞(1)的凿子部分(10) )当操作踏板(21)被释放以被关闭时被存储在锤体(7)中,其中通过将液压转换为液压来升高或降低锤击体(7)中的锤击活塞(1) 通过锤击活塞(1)的凿子部分(10)直接锤击破碎的物体。
