    摘要： An improved surgical tool of the type comprising handle means having a movable tool-operating handle member, a tool head having first and second tissue-engaging members movable between open and closed positions relative to one another, and means coupling the tool head to the handle means for causing opening and closing movement of the tissue-engaging members in response to manipulation of the movable tool-operating handle member. The improved tool is characterized by an inner shaft secured to a stationary part of the handle means, and a hollow outer shaft disposed in telescoping relation to the inner shaft, with the tool head being secured to the inner shaft and the outer shaft being movable axially relative to the inner shaft by manipulation of the movable tool-operating handle member, with the outer shaft causing opening and closing of the tissue-engaging members as it undergoes telescoping movement. Means are provided for concealing movement of the outer tube, particularly when the tool head is a surgical scissors head. Means are also provided for selectively rotating the tool head relative to the handle means.

    摘要： An improved surgical tool of the type comprising a handle assembly having a movable tool-operating handle member, a tool head having first and second tissue-engaging members movable between open and closed positions relative to one another, and a mechanism coupling the tool head to the handle assembly for causing opening and closing movement of the tissue-engaging members in response to manipulation of the movable tool-operating handle member. The improved tool is characterized by an inner shaft secured to a stationary part of the handle assembly, and a hollow outer shaft disposed in telescoping relation to the inner shaft, with the tool head being secured to the inner shaft and the outer shaft being movable axially relative to the inner shaft by manipulation of the movable tool-operating handle member, with the outer shaft causing opening and closing of the tissue-engaging members as it undergoes telescoping movement. Preferably an opaque tubular member surrounds the hollow outer shaft so as to conceal movement of the outer shaft. The tool also may include a manually-operated mechanism for selectively rotating the tool head relative to the handle assembly.

    摘要： A device for snaring cord-like objects and a methods for using same to pass portions of the cord-like objects through tissue are provided. The device includes a shaft containing a wire assembly having an object capturing device at its distal end. The wire assembly is reciprocally movable relative to the shaft between a first position wherein the capturing device is located within the distal portion of the shaft, and a second position wherein the capturing device extends distally outwardly from the distal end of the shaft. An activation device is attached to the proximal end of the shaft and the proximal end of the wire assembly so as to allow the controlled axial movement of the wire assembly relative to the shaft, and so as to allow the shaft and the wire assembly to be rotated as a unit about the longitudinal axis of the shaft. The methods include snaring and grasping a length of cord-like material and passing the cord-like material through one or more layers of tissue. More particularly, the shaft may be inserted through the tissue, grasp the cord-like material and pull the cord-like material back through the tissue as the shaft is disengaged therefrom. Alternatively, the cord-like material may be grasped by the device, inserted through the tissue along with the distal portion of the shaft, released from the distal end of the shaft, and left extending through the tissue when the shaft is withdrawn. Further, various combinations of these alternatives may be utilized in order to lace the cord-like material through the tissue in any particularly desired manner.

    摘要： An improved surgical cannula and trocar system for use in laparoscopic surgery. The system includes a novel surgical cannula including shield means for protecting operating room personnel from accidental contact with the trocar's sharp tip. The surgical cannula also includes improved sealing means for reliably preventing fluids from passing through the cannula both when an instrument extends through the cannula and no instrument extends through the cannula.
