摘要： A portable, battery powered electrosurgical wave generator is usable in performing electrically driven medical procedures. The wave generator can be small and lightweight to enable a user to carry and use the wave generator in non-operating room type settings. The wave generator can include a control unit that generates output signals in each of a cutting mode, coagulation mode, and a bipolar mode. The control unit can use a single circuit structure to generate the output signals for the cutting, coagulation, and bipolar modes. The output signals can be generated solely from a voltage produced by an incorporated battery within the generator.

摘要： Cable connection systems allow for an electrosurgical return electrode to be simultaneously connected to multiple ESUs. The cable connection systems can include individual return cables for simultaneous connection to each of the ESUs. The cable connection system can also include a junction that joins, connects, or associates the return cables in a manner that allows for the multiple ESU cables to be electrically connected to the return electrode at a single connection point on the return electrode.

摘要： Embodiments are directed to various monopolar and bipolar electrosurgical scissor instruments. A monopolar electrosurgical scissor instrument includes one scissor blade that has an electrically conductive tapered edge, where the tapered edge is insufficiently sharp to shear or otherwise mechanically cut tissue. The scissors also include another electrically insulated scissor blade movably mounted to the first scissor blade. The second scissor blade includes a flat contact surface that is aligned with the tapered edge of the first scissor blade. The scissors further include a scissor body that includes a conductor that transfers electrical energy from an energy source to the tapered edge of the first electrically conductive scissor blade to electrically cut interlaying tissue located between the first electrically conductive scissor blade and the second electrically insulated scissor blade.

摘要： A universal fluid system connector creates an airtight seal between a variety of smoke evacuation system receptacles and various hoses. The universal connector includes a body and a seal having a plurality of radially extending flexible fins. A plurality of fins on the seal are disposed along the length of the body with the outer edges of the fins forming a frustoconical shape. The fins also include one or more flexion zones of various stiffness and one or more flexible fin extensions. The fins deform against the inner wall of a receptacle and form an airtight friction fit between the universal connector and the receptacle, regardless of the taper angle, size, threads, or other features of the receptacle.

摘要： An electrosurgical return electrode configured for operable association with a transponder detection unit. The return electrode includes a conductive element having an aperture array configured to allow passage of a magnetic, electric, or electromagnetic interrogation signal from the transponder detection unit through the conductive element and through the return electrode. The return electrode is positionable over a transponder detection unit such that the return electrode may be placed upon the transponder detection unit and a patient may be positioned upon the return electrode. The return electrode enables the detection of a transponder located on, within, and/or near the patient without the need for repositioning the patient relative to the return electrode and without the need for positioning an ancillary transponder reader or transmitter above the patient.

摘要： An electrode tip for use in performing electrosurgical operative procedures is disclosed. The electrode tip includes a main body that can receive electrical energy from an electrosurgical generator. The main body includes a working surface that communicates the electrical energy to patient tissue during the operative procedure. An insulative sheath is disposed around a portion of the electrode tip to prevent electrical energy from being communicated from the covered portions of the electrode tip to patient tissue. The insulative sheath has a leading edge that is shaped to minimize resistance to the movement of the electrode tip through patient tissue. The leading edge can be arcuately shaped or angled relative to a longitudinal axis of the electrode tip to provide the resistance reducing characteristics.

摘要： An electrode tip for use in performing electro surgical operative procedures to concentrate electrical energy communicated to the patient tissue is disclosed. The electrode tip includes a main body that can receive electrical energy from an electrosurgical generator. The main body includes a working surface defining a flash edge. The working surface communicates the electrical energy to patient tissue during an operative procedure. The flash edge concentrates the electrical energy as it is communicated to the patient tissue. The concentration of the electrical energy from the flash edge reduces excessive tissue damage surrounding an incision site and improves the efficiency of the electrode tip.

摘要： An electrosurgical return electrode for use in electrosurgery. The return electrode is self-limiting and self-regulating as to maximum current and temperature rise to prevent patient trauma. An inductor is coupled in series with the return electrode. The inductor counteracts at least a portion of the impedance of the return electrode and the patient to optimize the flow of the current when the amount of contact area between the patient and the return electrode is sufficient to perform electrosurgery. The inductor may also be variable to allow the overall impedance of the electrosurgical circuit to be adjusted and tuned to work properly and safely with a particular patient and the other equipment used to perform electrosurgery. A conductor member operates 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.

摘要： Methods, systems, and devices for applying and utilizing a water-soluble polymer on a surface to provide desirable properties, attributes and/or characteristics to the surface. In a first embodiment, the water-soluble polymer at least partially fills one or more pores of a fluoropolymer or a porous metal. In a second implementation, the water-soluble polymer is mixed into a base material and the mixture is applied as a coating layer onto the surface. Where the surface is an electrosurgical electrode tip, the desirable properties, attributes and/or characteristics may include the ability to attract water that assists in cooling and/or lubricating the tip, to create a low shear, sacrificial layer that protects and enhances the tip, to supply a radical scavenger or inhibitor that reduces damage at the tip, and/or to deposit factors, such as healing factors, from the tip onto one or more contact surfaces of the patient's body.
