    摘要： A flexible endoscopic dip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.

    摘要： A flexible clip applier includes a flat wire wound tubular coil, a pair of jaws at the end of the coil, end effector wires extending through the coil and coupled to the jaws, and a clip-advancing wire extending through the coil. A clip chamber is defined in the distal end of the coil. A clip pusher is provided at a distal end of the clip-advancing wire, and advances a clip into the jaws when the clip-advancing wire is moved distally. The jaws include channels in which a distalmost clip rides when the jaws are closed and the pusher is advanced, thereby causing the distalmost clip to be pushed over the tissue, and a distal anvil which operate to bend a portion of the clip to facilitate its retention on the clamped tissue. The device can push a clip with a force in excess of 1500 grams.

    摘要： A multifilar flexible rotary shaft includes a plurality of individual filaments which are not wound around each other or around a central core, a loose ensemble of filaments. The input ends of each filament are coupled to each other and the output ends of each filament are coupled to each other. Preferably all of the filaments are identical. A loose ensemble of N filaments can transmit N times the torque of a single filament, and will have N times the torsional stiffness of a single filament, while retaining the minimum radius of operation of a single filament. Since a loose ensemble of filaments does not have any appreciable contact forces among the filaments (because they are not forcibly twisted together), there is no appreciable internal friction or hysteresis. In order to appreciably eliminate all the hysteresis in such an ensemble of filaments, the filaments should be no more than loosely twisted together, if at all. The only reason for loosely twisting the wires together is to allow the ensemble to be easily handled and to insure that the individual wire filaments follow the same general curved path from one end to the other. Several practical applications of the invention are also disclosed.

    摘要翻译： 多针柔性旋转轴包括多个单独的细丝，它们彼此不缠绕或围绕中心芯，松散的细丝组合。 每个灯丝的输入端彼此耦合，并且每个灯丝的输出端彼此耦合。 优选地，所有的长丝是相同的。 N细丝的松散组合可以传播N倍的单丝的扭矩，并且将具有单丝的扭转刚度的N倍，同时保持单丝的最小操作半径。 由于长丝的松散组合在细丝之间没有任何明显的接触力（因为它们不被强制扭曲在一起），所以没有明显的内部摩擦或滞后。 为了明显地消除这种灯丝组合中的所有滞后现象，如果有的话，灯丝不应该松散地扭曲在一起。 将电线松散地缠绕在一起的唯一原因是允许集合容易地处理并且确保单个线丝沿着从一端到另一端的相同的一般弯曲路径。 还公开了本发明的几个实际应用。
