    摘要： A safety shield is provided for an elongate needle cannula having a proximal end and a sharply pointed distal tip. The safety shield includes an anchor fixedly disposed near the proximal end of the needle cannula. The safety shield further includes a tip guard that is slidably movable along the needle cannula from a proximal position near the anchor to a distal position where the tip guard protectively surrounds the distal tip of the needle cannula. An elongate spring tether formed from a resiliently deflectable material has a proximal end connected to the anchor and a distal end connected to the tip guard. The spring tether is deflected into a loop about an axis extending orthogonal to the needle cannula when the tip guard is in the proximal position. The spring tether has a length which permits the tip guard to slide into its distal position without sliding completely of the distal end of the needle cannula. Resiliency of the spring tether keeps the tip guard in its proximal position. However, after sufficient manually generated movement of the tip guard in a distal direction, the resiliency of the spring tether will propel the tip guard into its distal position for safely shielding the tip of the needle cannula.

    摘要翻译： 为具有近端和锐尖的远端的细长针管提供安全屏蔽。 安全护罩包括固定地设置在针套管的近端附近的锚固件。 安全护罩还包括一个可沿着针管从靠近锚固件的近端位置滑动地移动到远侧位置的尖端保护装置，其中尖端保护装置保护性地围绕针套管的远端。 由弹性可偏转材料形成的细长弹簧系绳具有连接到锚固件的近端和连接到尖端防护件的远端。 当尖端防护件处于近端位置时，弹簧系链绕着与针插管正交延伸的轴线偏转成环路。 弹簧系绳具有允许尖端护罩滑动到其远侧位置的长度，而不会完全滑动针套管的远端。 弹簧系绳的弹性保持尖端护罩处于其近端位置。 然而，在尖端保护装置在远端方向上的足够的手动产生的运动之后，弹簧系绳的弹性将推进尖端护罩进入其远侧位置，以安全地屏蔽针套管的尖端。

    摘要： An applicator for applying a strap around a vein at the site of a defective venous valve includes a handle portion and a removable cartridge. One end of the strap is anchored on the anvil of the cartridge and the free end is looped around the vein and passed through an opening in the cartridge to overlie the anchored end. The free end of the strap is connected to a strap puller within the cartridge which is coupled to a strap puller extension within the handle when the cartridge is inserted in the handle. The perimeter of the loop is adjusted by moving the tensioner on the handle. When the loop perimeter is at its desired value, the triggers on the handle are pressed to drive a staple through the overlying portion of the strap. A knife within the cartridge cuts the excess strap from the loop.
