  • Patent number: 9375253
    Abstract: An electrosurgical instrument that reduces the amount of fatigue experienced by a physician performing electrosurgery includes a hand piece with a utility conduit connected to the hand piece. The utility conduit can include an electrical cable and a smoke/fluid evacuation hose. The location at which the utility conduit exits the hand piece is selectively adjustable to reduce the resistance to the movement of the electrosurgical instrument created by the weight of the utility conduit. An electrosurgical instrument may also include an extendable shaft that allows for selective adjustment of the reach of the operational capabilities of the instrument.

  • Publication number: 20150182280
    Abstract: A self-limiting electrosurgical return electrode for use with electrosurgical procedures is disclosed. The return electrode includes a conductive element and pads disposed on opposing sides of the conductive element. The conductive element, optionally in combination with the pads, is configured to limit the density of electrical current that passes from a patient to the return electrode. The conductive element and the pads can cooperate to define two separate working surfaces on opposing sides of the return electrode. The return electrode can also be safely used with patients of substantially any size and without requiring adjustments to the power settings of an electrosurgical generator.

  • Patent number: 8932280
    Abstract: Systems, methods, and instruments associated with controlling the operating modes of an electrosurgical instrument using control signals delivered in a wireless manner from the electrosurgical instrument to an electrosurgical generator. The electrosurgical instrument transmits wireless control signals to the electrosurgical generator to initiate delivery of electrosurgical energy. The control signals are delivered to the electrosurgical generator without the need for a conductive cord extending between the electrosurgical generator and the electrosurgical instrument. The energy is delivered to the electrosurgical instrument, in response to the wireless control signals, along a path through an electrode and the physician utilizing the electrosurgical instrument and/or a conductive path external to the physician. The electrode upon which the physician rests provides a path for the electrosurgical energy and optionally prevents burning of the physician during an electrosurgical procedure.

  • Patent number: 8882767
    Abstract: An electrosurgical instrument that reduces the amount of fatigue experienced by a physician performing electrosurgery includes a hand piece with a utility conduit connected to the hand piece at a central portion of the hand piece. The utility conduit can include an electrical cable and a smoke/fluid evacuation hose. The hand piece can include a channel system that receives a portion of the utility conduit therein and allows a physician to adjust the location on the hand piece at which the utility conduit exits the hand piece. Adjusting the location on the hand piece at which the utility conduit exits the hand piece can reduce the resistance to the movement of the electrosurgical instrument created by the weight of the utility conduit, which leads to less fatigue in a physician's hand during electrosurgery.

  • Patent number: 7837680
    Abstract: An electrosurgical return electrode for use in electrosurgery. The return electrode is self-limiting and self-regulating as to current temperature and temperature rise so as to prevent patient trauma. According to one aspect of the invention, an inductor is coupled in series with the electrosurgical return electrode. The inductor is configured to optimize the flow of the electrosurgical current by minimizing the effective bulk impedance of the electrosurgical return electrode when the amount of contact area between the patient and the electrosurgical return electrode is sufficient to conduct electrosurgery. According to another aspect of the present invention, a conductor member is adapted for use with circuitry that indicates to a user when the contact area between the patient and the self-limiting member and/or return electrode is below a given threshold.

  • Publication number: 20100271592
    Abstract: Apparatuses and methods are provided for measuring the critical flicker fusion frequency of a subject. The apparatus in one aspect comprises two or more light sources, each flickering at a different predetermined frequency. The subject selects one light source from an array of light sources defining a first range of frequencies, the selection representing the light source of lowest frequency that appears as fused to the subject. The frequencies of the light sources are adjusted to second predetermined frequencies defining a second range. The subject selects the light source of lowest frequency that appears as fused to the subject. The frequency value of the second selection can be assigned as the subject's critical flicker fusion frequency.

  • Patent number: 7367971
    Abstract: A removable semi-insulating sheet for use in self-limiting electrosurgical return semi-insulating sheet for use with electrosurgery. Through the selection of impedance characteristics for the electrode materials of the principal body of the semi-insulating sheet, and through tailoring of semi-insulating sheet geometries, the return electrode of the present invention is self-regulating and self-limiting as to current density and temperature rise so as to prevent patient trauma. The semi-insulating sheet has an effective bulk impedance equal to or greater than about 4,000 ?·cm. The effective bulk impedance of the sheet may arise from resistive components, capacitive components, inductive components, or combinations thereof. The configuration of the presently described return electrode allows the electrode to self-limit the electrode's current densities, thereby preventing burning of a patient during surgery.

  • Patent number: 7255263
    Abstract: An electrosurgical apparatus having a counter/lockout mechanism that monitors the number of sterilization/use cycles the electrosurgical apparatus undergoes and indicates the number of sterilization/use cycles that have actually been performed. The counter/lockout mechanism includes a temperature actuated element actuated in response to each sterilization cycle and a mechanically actuated element in response to a use cycle to effectuate a change of one or a plurality of indicia. The counter/lockout mechanism causes a single increment or decrement for each sterilization/use cycle that has been completed while also impeding use of the electrosurgical apparatus when the electrosurgical apparatus has undergone a predetermined number of sterilization/use cycles. In one embodiment, the distance of movement of the mechanically actuated element when fully actuated is greater than the distance the indicator moves when illustrating a change in the number of remaining uses.

  • Patent number: 7225009
    Abstract: An interface unit for receiving a body part of a subject at which a noninvasive hematocrit measurement is to be obtained includes a narrow monitoring element with a receptacle for receiving at least a portion of the body part and contacts that are configured for establishing electrical communication with contacts of electrodes that are to be positioned over the receptacle before the body part is placed therein. In addition, the monitoring element may include a pressure port that communicates pressure into the receptacle. The interface unit also includes a cover which is configured to partially enclose the body part, to ensure that electrical communication is established between the contacts and the electrodes, and to facilitate the application of pressure to the body part. The electrodes may be in the form of electrically isolated electrode pairs, which may be formed as a strip with minimal material wastage.
