Abstract
A compression forceps with four bar linkage is formed of a stationary handle and jaw connected by a shank area; a moveable jaw; a moveable handle having the approximate shape of a bell crank with major and minor arms; and a connecting link member having first and second opposite ends. The four links are joined at pivots, with a first pivot connecting the major and minor arms of the moveable handle to the rear end of the shank area of the stationary handle and jaw. A second pivot connects the free end of the minor arm to a rear end of the moveable jaw. A third pivot connects a first end of the link to the front end of the shank area of the stationary handle and jaw. A fourth pivot connects the second end of the link to a middle area of the moveable jaw. The compound linkage thus formed operates the jaws with an increase of the relative inside angle between the jaws as the jaws close.
