Abstract
Abstract 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
110 words
Disposable forceps including a pair of elongated arms, each having a proximal end portion providing a handle and a distal end portion including means for attachment of a contacting member removably to each of the arms, hinge means for movably joining the arms to one another about an axis other than one which is parallel to the longitudinal axes of said arms to provide adjustment of the forceps, and means for adjustably rotatably receiving the intermediate portion of each arm about the longitudinal axis of said arm and for holding the arms in adjusted position relative to the hinge means, the rotatable adjustment means being connected to the hinge means.
Claim 2
Dependent Claim
110 words
Disposable forceps including a pair of elongated arms, each having a proximal end portion providing a handle and a distal end portion including means for attachment of a contacting member removably to each of the arms, hinge means for movably joining the arms to one another about an axis other than one which is parallel to the longitudinal axes of said arms to provide adjustment of the forceps, and means for adjustably rotatably receiving the intermediate portion of each arm about the longitudinal axis of said arm and for holding the arms in adjusted position relative to the hinge means, the rotatable adjustment means being connected to the hinge means.
Claim 3
Dependent Claim
27 words

Claim 11
Dependent Claim
63 words
The invention of claim 7 wherein the slot is defined by a pair of opposed walls, each wall including an indentation, and the contacting members include side walls provided with corresponding opposed raised bearing surfaces to provide a snap-fit of the contacting members into the slots, and to provide for frictional pivoting of the contacting members relative to the ends of the arms.
Claim 12
Dependent Claim
245 words
Disposable forceps for holding open a body orifice or incision, the forceps including a pair of contacting members and a pair of elongated arms, each arm having a proximal end portion providing a handle and a distal end portion formed for removable attachment of a respective contacting member thereto, and a hinge means for movably joining the arms to one another intermediate their ends and about an axis other than one which is parallel to the longitudinal axes said arms, means for adjustably rotatably receiving the intermediate portion of each arm about the longitudinal axis of said arm and for holding the arms in adjusted position relative to the hinge means, the rotatable adjustment means being connected to the hinge means, each contacting member including an outwardly-bent portion for hooking the contacting members under the tissue defining the orifice or incision to prevent slippage of the contacting members from the orifice or incision and resulting closing of the orifice or incision, the distal end portion providing a pair of opposed walls defining a slot, the contacting members being sized for insertion into respective slots, one of the pair of opposed walls and contacting members providing a pair of aligned, raised bearing surfaces, and the other of the pair of opposed walls and contacting members providing a pair of aligned indentations for engagement by the bearing surfaces to provide a snap-fit and frictional pivoting of the contacting members relative to the ends of their respective arms.
