Abstract
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.
