  • Patent number: 11033314
    Abstract: Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can include a rotatable drive shaft that urges first and second portions of a modular bending or cutting template toward one another to bend or cut an implant disposed between the template portions. A linkage assembly can be included to provide a mechanical advantage in urging the template portions toward one another. In some embodiments, an instrument can include a rotatable drive shaft that, depending on direction of rotation, pushes or pulls a first modular template portion with respect to a second modular template portion to bend an implant disposed between the template portions in one direction or another direction. In some embodiments, an instrument can include a worm drive that rotates a cutting wheel with respect to a cutting plate to cut an implant inserted through openings formed in the cutting wheel and the cutting plate.

  • Patent number: 8307557
    Abstract: A foot operated cutter has an elongated handle with a pair of cutting jaws mounted on one end thereof and a gripping member at the other end thereof. The cutting jaws are mounted on separate spaced apart pivot axles. The upper end of each jaw is pivotally coupled to a movement arm and the two movement arms are pivotally coupled to each other. One movement arm is coupled to a foot operable lever. Movement of the lever causes the movement arms to pivot and move the upper ends of the jaws apart from each other resulting in the lower ends of the jaws coming together in a cutting action. A biasing member preferably urges the jaws to an open position. An adjustable stop is preferably provided and prevents the lever from putting too much force on the jaws.

  • Publication number: 20100229396
    Abstract: A hand-held hair cutting appliance has a housing, a first cutting blade, and a second cutting blade. The first cutting blade is capable of reciprocating movement relative to the housing. A drive assembly is operatively connected to the first cutting blade for drivingly reciprocating the first cutting blade relative to the housing such that the first cutting blade is moveable in a side to side direction relative to the housing and the second cutting blade. A counter weight is adapted for reciprocating movement relative to the housing in response to reciprocating movement of the first cutting blade. The counter weight has at least one of a mass and a location relative to the first cutting blade to thereby at least partially counter-balance the reciprocating movement of the first cutting blade.

  • Patent number: 7386940
    Abstract: A pair of hairdressing scissors and a positioning device thereof, the pair of hairdressing scissors having a connecting structure formed with a recess, a protrusion and a through hole. A positioning device is disposed in the through hole and includes a retaining member, an elastic member and a fixing member. When coupling a plurality of pairs of hairdressing scissors together, the protrusion of a pair of hairdressing scissors is engaged in the recess of another pair of hairdressing scissors. The protrusion moves toward and presses the retaining member, so that the retaining member will overcome the elastic force of the elastic member and retract into the through hole.

  • Patent number: 6748662
    Abstract: A hairdressing scissor assembly includes at least two pair of scissors each having a first scissor element and a second scissor element pivoted to the first scissor element. Each of the first scissor element and the second scissor element includes a handle. A first engaging element is formed on a first side of a first connecting member and releasably engaged with a side of one of the handles of one of the pairs of scissors. A second engaging element is formed on a second side of the first connecting member and releasably engaged with the other side of one of said handles of the other pair of scissors. The first connecting member can be replaced by a second connecting member having a thickness different from that of the first connecting member, thereby allowing a change in a spacing between the pairs of scissors.
