Abstract: A system and a method are disclosed for disconnecting clips. A clip separation tool includes two arms, the arms having jaws to receive connected clips at a distal end of the arms and handle portions on a proximal end for a user to engage the tool with his hand. A pivot mechanism is coupled to the arms, where, responsive to a force applied to the handle portions, the arms rotate relative to each other around the pivot mechanism such that the distal ends of the arms pivot away from one another and the proximal ends of the arms pivot towards one another. A spring biases the arms to rotate to an equilibrium position that is attained automatically under spring loading once the proximal ends of the arms are relieved of loading. The clip separation tool disconnects connected clips as the force causes the arms to rotate around the pivot mechanism.

Abstract: The invention comprises tools for forming beads on one or more filaments using a malleable material for the bead. The tools exert bead-forming forces radially inward toward the filament and axially along the filament toward the center of the bead. The tools comprise pliers with jaws which meet flush with each other over at least a portion of the jaw face. Aligned cavities are formed in each jaw face wherein each cavity's dimension across the jaw face is less than the width of the jaw face. Grooves, aligned generally transverse to the width of the jaw face provide a filament-receiving channel between the cavity and the edge of the jaw face. Malleable material encompassing the filament is aligned between the aligned cavities and the jaws are closed. The radial force of the cavity walls on the malleable material deforms the malleable material radially and the walls of the cavity exert a force axially to form a bead.

Abstract: This patent describes a new orthodontic instrument to be used for tying or twisting the ligature wires used to hold the arch wire to the bracket. It also explains the method of use which consists of: twisting the wires, after the ligature wire has been placed on the bracket; tucking the twisted end out of the way; and then breaking the end at the tip of the instrument. The instrument replaces three instruments normally used, by improvements in jaw design to facilitate grasping and centering the wires for spinning, balancing the instrument by general symmetry, and the addition of an extension handle to allow rapid spinning, and tucking of the wire ends as they are broken in a controlled manner, and at a specific place. The instrument thus simplifies, speeds and further improves the application of ligature wires.
