    摘要： A surgical fastener with a safety position includes a lower base having piercing posts each having fixed and coupling ends, first and second base portions respectively attached to the posts, a hinge coupling the base portions, and a bias device imparting force on at least one base portion toward the other and at an angle to the hinge axis. Also provided is an upper fastening portion receiving and selectively coupling the posts. The lower base has a piercing position for coupling with the upper fastener portion where the posts are substantially parallel and a folded position where a distance between a coupling end of the first piercing post and the coupling end of the second piercing post is less than a distance between the fixed end of the first piercing post and the fixed end of the second piercing post.

    摘要： An endoscopic needle device includes an inner fluid conduit, an outer sheath extending over the length of the conduit, a longitudinally stiff wire extending through the conduit, and a needle fixedly attached to the distal end of the conduit. The distal end of the wire is coupled to one or both of the needle and the distal end of the conduit. The needle includes a proximal opening such that the hollow of the needle is in fluid communication with a lumen of conduit. A proximal handle includes a stationary member and a movable member longitudinally movable relative to the stationary member. The proximal end of the outer sheath is coupled to the stationary member, and the stationary member includes structure to mount the handle to a port of an endoscope. The movable member includes a passageway, and the proximal end of the conduit is coupled to the distal end of the movable member, and a port is provided at the proximal end of the movable member. A syringe may be coupled to the port and operated to inject a fluid which travels through the passageway, the lumen of the conduit, and the needle. In addition, the proximal end of the wire is coupled to the movable member. The handle assembly also includes a knob rotatably coupled to the stationary member, wherein rotation of the knob results in reciprocal movement of the movable member relative to the stationary, and consequently the needle relative to the distal end of the outer sheath.

    摘要： An endoscopic needle device includes an outer sheath, an elongate shaft extending through the sheath, a needle rigidly attached to the distal end of the shaft, and a handle assembly having a housing coupled to the proximal end of the sheath and having a syringe port in fluid communication with the sheath and a knob rotatably coupled to the housing. Rotation of the knob relative to the housing causes rotation of the shaft relative to the sheath. The needle and the distal end of the sheath are mated by a threaded connection. As such, rotation of the knob relative to the housing causes precise longitudinal movement and extension of the needle relative to the distal end of the sheath. A set of intermeshing gears are provided between the knob and shaft which function to permit at most one rotation of the knob to cause complete extension and/or retraction of the needle. Furthermore, assemblies are provided with permit the shaft to accommodate movement of the needle relative to the sheath. Moreover, the position of the knob relative to the housing provides an indication of the extension of the needle. As such, the injection needle device of the invention permits controllable and calibrated rotation of the needle to within a few degrees, such that the needle device can be easily, reliably, and precisely operated to advance the needle.

    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。

    摘要： An endoscopic surgical instrument for deploying a two part fastener having a male fastener part and a female fastener part, includes a tube having a proximal end and a distal end. An end effector is coupled to said distal end of said tube and is configured to hold the male fastener part and the female fastener part in opposed relation. An actuator is coupled to said proximal end of said tube and is configured to actuate the end effector. A shearing device may be positioned proximate the end effector to shear off a tip of the male fastener part after the male and female fastener parts are moved into locking relation. In addition, the surgical instrument may include a male fastener part having a shaft with a plurality of detent positions. Further, the male fastener part may include a base and a shaft pivotally connected to the base.
