    • An endoscopic surgical instrument includes a proximal handle with a distally extending lever actuator. The handle and lever actuator are coupled by a tube and push rod to a pair of distal end effectors. The proximal end of the tube is mounted in a bushing having a flange which is freely rotatable within a flange receiving recess in the handle. The proximal end of the push rod extends proximally beyond the bushing and is coupled to the lever actuator by a ball and set screw coupling. The lever actuator preferably extends at least four inches distally from the proximal end of the handle and includes a finger ring near its distal end. The tube is preferably provided with a ferrule immediately distal of the handle for rotating the tube and push rod about the longitudinal axis of the instrument. The ferrule is preferably provided with a distal extension having an annular notch for locking engagement inside another endoscopic instrument. The lever actuator imparts a force to the end effectors which is magnified relative to the force applied to the actuator. The distal extension of the lever actuator and the finger ring allow the instrument to be operated with one finger while the instrument is grasped by the ferrule or mounted inside another endoscopic instrument.
    • 内窥镜手术器械包括具有远端延伸的杠杆致动器的近侧手柄。 手柄和杠杆致动器通过管和推杆联接到一对远端执行器。 管的近端安装在具有凸缘的衬套中,凸缘可在手柄中的凸缘容纳凹部内自由旋转。 推杆的近端向近侧延伸超过衬套,并通过球和定位螺钉联接件联接到杠杆致动器。 杠杆致动器优选地从手柄的近端向远端延伸至少四英寸,并且在其远端附近包括指环。 管优选地设置有紧靠手柄远侧的套圈,用于旋转管并且推动杆围绕器械的纵向轴线。 套圈优选设置有具有环形凹口的远侧延伸部,用于将锁定接合在另一内窥镜器械内。 杠杆致动器向终端执行器施加力,相对于施加到致动器的力被放大。 杠杆致动器和指环的远侧延伸部件允许仪器在一个手指操作时,同时仪器由套圈抓住或安装在另一个内窥镜仪器内。

    • An endoscopic multiple sample bioptome includes a hollow outer member and an axially displaceable inner member extending therethrough. The proximal ends of the outer and inner members are coupled to an actuator for axially displacing one relative to the other. The distal end of the outer member is coupled to one of a cylinder having a sharp distal edge and a jaw assembly, while the distal end of the inner member is coupled to the other. The jaw assembly includes a pair of opposed, preferably toothed jaw cups each of which is coupled by a resilient arm to a base member. The arms are bent to lie in planes which intersect the axis of the base member and to locate the jaws apart from each other. The base member is mounted inside the cylinder and axial movement of the jaw assembly and cylinder relative to each other draws the arms into the cylinder and brings the jaw cups together in a biting action. The biting action is enhanced according to the invention by arranging the cutting edge of each jaw to lie in a plane which intersects the plane in which the distal portion of the jaw arm lies. The biting action is further enhanced by providing a closing cam on the outer surface of the jaws which is engaged by the cylinder when the jaws are closed. The arrangement of the cutting edges also presents a smooth surface to the interior of an endoscope and the closing cams prevent the sleeve from sliding completely over and off of the jaws.
    • 内窥镜多样本生物切割器包括中空的外部构件和从其延伸穿过的可轴向移动的内部构件。 外部构件和内部构件的近端联接到致动器,用于相对于另一个轴向移动。 外部构件的远端联接到具有尖锐远端边缘和钳口组件的圆柱体中的一个,而内部构件的远端联接到另一个。 钳口组件包括一对相对的,优选有齿的钳口杯,每个钳口由弹性臂联接到基座构件。 臂被弯曲以位于与基部构件的轴线相交的平面中并且将夹爪彼此分开定位。 基座部件安装在气缸内,夹爪组件和气缸相对于彼此的轴向运动将臂插入气缸中,并使咬合杯以咬合动作一起接合。 根据本发明,通过将每个钳口的切割边缘布置在与钳口臂的远端部分所在的平面相交的平面中,根据本发明增强了咬合动作。 通过在钳口的外表面上设置关闭凸轮来进一步增强咬合动作,当闭合钳口时,该闭合凸轮由气缸接合。 切割边缘的布置还呈现出内窥镜内部的光滑表面,并且闭合凸轮防止套筒完全滑过和夹紧夹爪。
