    • Microsurgical instruments for performing extremely small-scale, minimally-invasive microsurgery such as thoracoscopic coronary artery bypass grafting. The instruments utilize a symmetrical, forcep-like actuator which provides extremely precise actuation and control of the instrument and which mimics the feel of instruments used in conventional open surgical procedures. The instruments generally include a pair of coaxially arranged shafts, an end-effector at the distal ends of the shafts, and an actuator at the proximal ends of the shafts. The actuator includes a pair of arms pivotally coupled to one of the outer and inner shafts, and a pair of links pivotally coupled at one end to the arms, and at a second end to the other of the shafts. The links are coupled to a proximal portion of the arms to maximize mechanical advantage and reduce interference. The actuator may be easily adapted for either pull-type or push-type actuation, and for either outer shaft or inner shaft translation. The actuator is provided with a locking mechanism for fixing the relative position of the shafts to maintain the end-effector in a closed position. The locking mechanism includes rigid catches that are engaged upon actuation of the actuator and are disengaged upon further actuation of the actuator. The end-effectors may have a variety of configurations, including needle drivers, forceps, scissors, and clip appliers.
    • 显微手术仪器用于进行极小型,微创微创手术,如胸腔镜冠状动脉旁路移植术。 仪器采用对称的强力致动器,它提供了非常精确的致动和控制仪器,并且模拟了常规开放式外科手术中使用的仪器的感觉。 仪器通常包括一对同轴布置的轴,在轴的远端处的末端执行器和在轴的近端的致动器。 致动器包括可枢转地联接到外轴和内轴中的一个的一对臂,以及在一端枢转地连接到臂的一对连杆,并且在另一端处连接到另一个轴。 连杆联接到臂的近端部分以最大化机械优点并减少干扰。 致动器可以容易地适用于拉式或推式致动,以及用于外轴或内轴平移。 致动器设置有用于固定轴的相对位置的锁定机构,以将末端执行器保持在关闭位置。 锁定机构包括在致动器致动时接合的刚性卡盘,并且在进一步致动致动器时脱开。 末端执行器可以具有各种配置,包括针驱动器,镊子,剪刀和夹具装置。
