    • A surgical forceps (10) particularly useful in least invasive surgery includes an elongate probe formed of an outer tubular member (12) and an inner member (18) movable in the outer probe member, stationary and movable jaws (24,26) coupled with the distal ends, respectively, of the outer and inner probe members, and a handle (150) squeezable to move the movable jaw relative to the stationary jaw to rearwardly or forwardly cut tissue or to grasp tissue. A force diverting mechanism (166,172) is responsive to the force applied to the handle exceeding a predetermined force to provide the surgeon with an indication of the excessive force and protects the jaw components at the distal end of the surgical forceps. A suction passage is formed in the forceps for aspirating cut tissue and assisting the positioning of tissue between the jaws, and suction can be produced continuously or controlled via the handle. The handle includes locking and latching mechanisms (184,178) to hold the jaws in a closed position.

    • In an endoscope having a focusing ocular, a disposable probe includes a transfer module assembly with one or more relay modules (28, 30, 32), and an objective group (24) comprised of a distal glass window (34), a molded plastic prism (36) and three molded plastic lenses (38, 40, 42). Each relay module contains an entry glass rod, an intermediate glass rod, and an exit glass rod, each rod having flat end surfaces, and two identical molded plastic doublets. In certain embodiments, each relay module further includes identical molded entry and exit field lenses. In one preferred embodiment, the ocular comprises several glass elements, including an axially movable focusing element and two non-movable doublets. The disposable probe introduces predetermined optical aberration into the image, and the focusing ocular specifically corrects this aberration. The ocular is typically not disposable. A single curved surface is formed on the distal glass window of the probe; all other curved optical surfaces of the disposable probe are formed on molded plastic members, thereby reducing the cost of the probe sufficiently to be cost-effective for single patient, disposable use.
    • 在具有聚焦目镜的内窥镜中,一次性探头包括具有一个或多个继电器模块(28,30,32)的转移模块组件和由远端玻璃窗(34),模制塑料 棱镜(36)和三个模制塑料透镜(38,40,42)。 每个继电器模块包括入口玻璃棒,中间玻璃棒和出口玻璃棒,每个棒具有平坦的端面,以及两个相同的成型塑料双体。 在某些实施例中,每个继电器模块还包括相同的模制进入和离开场透镜。 在一个优选实施例中,眼睛包括若干玻璃元件,包括可轴向移动的聚焦元件和两个不可移动的双峰。 一次性探头将预定的光学像差引入到图像中,并且聚焦目标特异性地校正该像差。 眼睛通常不是一次性的。 在探头的远端玻璃窗上形成单个曲面; 一次性探头的所有其它弯曲光学表面形成在模制的塑料构件上,从而将单个患者,一次性使用充分地降低探针的成本成本效益。

    • A suture cutting device is provided, the device suitable for cutting high strength suture materials used in arthroscopic surgeries. The device includes a blade (12) having distal blade portion movable within a distal suture guide, the distal suture guide including a lateral suture guide slot (54). The distal blade portion includes a dorsal recess (70) that, in combination with an upper wall of an enclosed blade guide slot, controls an amount of dorsal movement of a cutting edge during a longitudinal movement of the cutting edge. The combined dorsal movement and longitudinal movement of the cutting edge creating a sliding/slicing movement of the cutting edge against a suture in the suture guide slot. At least a proximal blade portion and an extension blade portion are made of a single blade, those portions defining a spring, contacting a trigger, and effectuating a movement from a first position to a second position.
    • 提供缝合切割装置,该装置适用于切割用于关节镜手术的高强度缝合材料。 该装置包括具有可在远端缝合线引导件内移动的远侧刀片部分的刀片(12),远端缝合线引导件包括横向缝合线引导槽(54)。 远端叶片部分包括背部凹部(70),其与封闭叶片引导槽的上壁组合控制切割刃在切割刃的纵向移动期间的背部运动量。 切削刃的组合的背部运动和纵向运动产生切削刃相对于缝合线引导槽中的缝线的滑动/切片运动。 至少近侧叶片部分和延伸叶片部分由单个叶片制成,这些部分限定弹簧,接触触发器,并实现从第一位置到第二位置的运动。
