The device further has an amplifier in communication with said electrical waveform that amplifies said waveform to create an output signal and an electrosurgical connector configured to receive an electrosurgical instrument and to pass said electrical signal to said electrosurgical instrument. The controller further modulates the discrete packets to form sub-discrete packets and a second level of sub-discrete packets. A feedback circuit in continuous communication with sensing circuits positioned in the electrosurgical instrument receives electrical power usage data from the operative field and determines adjustments to power supply based on power usage data.

  • Patent number: 9113854
    Abstract: A tissue retractor device suitable for spinal surgery. The device includes base apparatus to which three blades are circumferentially hinged, the blades closing upon each other in default position from spring bias. A pusher mechanism is threadably connected to the base which spreads the blades by rotating the pusher in its threads relative to the base, which converts rotational motion to translational motion to angular motion of the blades about their respective hinges. One blade is longer than the others to present a multipurpose tip to the user of the device, such a tip being useful in avoiding nerve roots or other anatomy obstructing the surgical path. A dilator is threadably connected to the pusher, the dilator having a long hollow tube connected to a hollow tip extending beyond the blades to slide over guide-wire and initially position the device at the operative site, prior to using the pusher to retract patient's tissue.

  • Patent number: 9028491
    Abstract: An electrosurgical handpiece comprising a squeezable handle connected to extend and retract bipolar electrodes from a rigid tubular member. The bipolar electrodes comprise active separable distal ends and connecting links configured such that when the handle is unsqueezed, the active distal ends protrude from the distal end of the first tubular member and are adjacent one another, and when the handle is fully squeezed, the active distal ends are fully extended outwardly from the first tubular member and separate, and when the handle is relaxed but still partially squeezed, the active distal ends come together and touch first at their extreme ends and then touch over a broader area in a position to grasp tissue for receiving electrosurgical currents.

  • Patent number: 8998891
    Abstract: An electrosurgical instrument that is capable of generating high-quality RF energy carriers at one of three different frequencies and combining any of the three carriers with any one of four electrosurgical mode waveform modulations and selectively supplying the modulated carriers to either a monopolar or a bipolar handpiece. In a preferred embodiment, the first carrier frequency is in the range of about 3.8-4.0 MHz, the second carrier frequency is in the range of about 1.7-2.0 MHz, and the third carrier frequency is in the range of about 400-600 KHz.

  • Patent number: 8992524
    Abstract: An electrosurgical Cobb elevator instrument, a soft tissue dissection and/or retraction tool, can be used with and without suction, and is capable of delivering monopolar or bipolar RF energy for cutting and coagulating soft tissue. The device is capable of footswitch or handswitch activation. The tool has a spoon-shaped edge that is preferably sharp to provide blunt dissection in addition to the energy-driven dissection. The instrument of the invention could be used in any procedure that requires soft tissue dissection and/or coagulation.

  • Patent number: 8894574
    Abstract: A tissue retractor device for retracting tissue includes a base and a plurality of blades connected to and distributed around said base. Each of the blades is outwardly movable from the base and includes a respective sloped portion on an interior region of the blades. The tissue retractor includes a pusher engaged to the base. A portion of said pusher abuts the sloped portion of each of the blades. Movement of the pusher in a longitudinal direction engages a portion of the pusher against said sloped portion of each of the blades to move the blades and angularly displace the blades between a respective closed position and an open position.
