摘要： A tool and method is provided for attaching an endcap to a medical instrument such as an endoscope tip, wherein the endcap includes an elastically deformable, endcap opening having an unexpanded diameter that is smaller than the diameter of the instrument tip and an expanded diameter that is greater than the diameter of the instrument tip. The tool has a first component adapted to hold the endcap and to receive the instrument tip and a second component operatively associated with the first component and movable with respect to the first component, wherein the second component is adapted to apply a force to the first component. The endcap opening may be elastically deformed to have the expanded diameter prior to positioning the endcap at a desired longitudinal location and angular orientation with respect to the endoscope tip.

摘要： In accordance with the present invention, there is provided a surgical device for attaching a first hollow organ to a second hollow organ and creating a passageway therebetween. The device includes a first member comprising a first prong for entering a wall of the first hollow organ and a second prong for entering a wall of the second hollow organ. The prongs each have a proximal end which attaches to the first member and a distal end extending therefrom. The device further includes a second member having a plow for incising at least one of the hollow organs so as to create a passageway between the hollow organs. The second member further includes a plurality of needle paths on either side of the plow for guiding a needle through the walls of the hollow organ on either side of the passageway. The device further includes a means for driving a needle, having a suture attached thereto, so as to attach the hollow organs together. Lastly, the device includes a frame for coupling the first member and the second member together in operational engagement.

摘要： A four-bar linkage for an articulation assembly adapted for use with a surgical instrument is disclosed. The first link is in the form of an actuation lever which pivots transversely to the longitudinal axis of the instrument. The second and third links are operatively connected to the first link. The fourth link is in the form of an end effector for the instrument, and it is rotatably attached to the second and third links for movement transverse to the longitudinal axis. When the first link is pivotally rotated, a driver assembly causes the second and third links to move in tandem generally parallel to the longitudinal axis of the instrument in opposite directions. Consequently, the end effector rotates in the same direction as that of the actuation lever from an unarticulated position to an articulated position. The four-bar linkage is simple and efficient, and eliminates the need for a conventional central pivot for the articulation joint. By making the linkage the primary structural support of the end effector, clearance can be provided centrally between the second and third links to allow for the passage of additional linkages and members which are needed to actuate the end effector to carry out various surgical functions.
摘要翻译：公开了一种用于与外科器械一起使用的关节运动组件的四杆连杆机构。第一连杆是致动杆的形式，该致动杆横向于仪器的纵向轴线枢转。第二和第三连杆可操作地连接到第一连杆。第四连杆是用于仪器的端部执行器的形式，并且其可旋转地附接到第二和第三连杆件以横向于纵向轴线移动。当第一连杆枢轴转动时，驱动器组件使得第二和第三连杆在大致平行于仪器的纵向轴线的方向上以相反方向移动。因此，末端执行器沿与驱动杆的方向相同的方向从未分配位置旋转到铰接位置。四杆联动是简单和有效的，并且不需要用于关节接头的常规中心枢轴。通过使连杆机构作为末端执行器的主要结构支撑件，间隙可以设置在第二和第三连杆之间的中心，以允许额外的连杆和构件的通过，这些连杆和构件是致动末端执行器以执行各种外科功能所需要的。

摘要： A clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.
