<p>A pair of disposable plastic forceps includes elongated arms, each having a proximal end portion providing a handle and a distal end portion for attachment of a contacting member to each of the arms, and a hinge for movably connecting the arms to one another to provide adjustment of the forceps, the hinge joining the arms intermediate their ends. Desirably, the hinge rotatably and frictionally receives the intermediate portion of each arm to hold the arms in position relative to the hinge after they are adjusted. The distal end of each arm is formed to provide a slot for removably receiving a contacting member. Contacting members of various sizes and shapes are provided, the size and shape selected being dependent in part upon the function to be performed by the forceps. The slot in each arm is defined by a pair of opposed walls. The contacting members include side walls which engage the opposed walls of the slot. Either the walls of the slot or the side walls of the contacting member can be provided with opposed raised bearing surfaces, the remaining pair of walls being provided with indentations to provide a snap-fit of the contacting members into the slots and pivotal frictional contact of the contacting members relative to the ends of the arms. In this manner, the contacting members can be adjusted on the ends of the arms, or can readily be exchanged for contacting members having a different size and/or shape.</p> |
