摘要： This invention is a reusable electrosurgical electrode pad (41) for use with electrosurgery. In one embodiment, it includes a presentation or working surface area lying in the range of from about 11 square inches to about 1,500 square inches. In another, the working surface is at least as large as that of a projection of about half of the profile of the trunk of a patient. In yet another, it includes a working surface area at least as large as that of a projection of the profile of both the trunk and legs of a patient. It is adapted for disposition on the working surface of an operating table (42) or dentist's chair immediately underlying a patient during electrosurgery. By presenting a very large surface area, the need for direct contact or contacts through conducting jells is eliminated. Through employment of washable surface areas, it is made readily cleanable and reusable. Through the inclusion of capacitive coupling and selection of impedance characteristics for the materials and geometries, it is made self-limiting as to current density and temperature rise so as to prevent patient trauma. An optional sleeve (50) is provided for cooperative use with the electrode.

摘要： A smoke evacuation device includes one or more cooling mechanisms and an exhaust mechanism to reduce velocity and noise of filtered air exiting the smoke evacuation system. The cooling mechanism includes ventilation openings and/or a rotary mechanism disposed within the system to circulate air and cool by convective heat transfer. A pressure relief mechanism is also provided at the inlet or outlet of the system or the pump within the system. The pressure relief mechanism is configured to reduce pressures due to abnormal flows within the smoke evacuation system.

摘要： Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.

摘要： A hand-held instrument has a distal section and a proximal section joined by an attachment piece. The attachment piece enables the distal section to be swiveled/rotated independent of the proximal section. A tip, such as an electrode tip, is coupled to the distal end of the distal section and rotates with the distal section, enabling a user to adjust the rotational orientation of the tip during use.

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： 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.

摘要： A self-limiting electrosurgical electrode for use with electrosurgery and various other surgical procedures is disclosed. The electrode includes a heating element for generating heat to warm a patient resting upon the electrode. The electrode can also include one or more pads to prevent the creation of pressure sores or decubitus ulcers on a patient resting upon the electrode. The electrode has an effective bulk impedance equal to or greater than about 4,000 Ω.cm, which arises from resistive components, capacitive components, inductive components, or combinations thereof. Through the selection of the impedance characteristics for the electrode materials, and through tailoring of electrode geometries, the electrode of the present invention is self-regulating and self- limiting as to current density and temperature rise so as to prevent patient trauma.

摘要： A capacitive reusable electrosurgical return electrode pad (60) for use with electrosurgery. Through selection of the electrode geometries and the impedance characteristics of the electrode, the electrode is self-regulating and self-limiting as to current density and temperature rise so as to prevent patient trauma. The electrosurgical return electrode can include a connector and a sheet of material having an effective bulk impedance equal to or greater than about 100,000 ohm cm. The electrode can have a working surface area from about 11 to about 1,500 square inches (or about 70 to about 10,000 square centimeters). The electrode can be disposed on the working surface of an operating table or dentist's chair immediately underlying a patient during electrosurgery. This very large working surface area eliminates the need for direct contact or contact through conducting gels and by employing washable surface areas, it is made readily cleanable and reusable.

摘要： A system for noise and vibration management of a smoke evacuation system includes a pump that compresses air and produces a pressure differential within an airflow path. The pump may be a sealed, positive displacement pump. The system includes vibration absorption mechanisms disposed between inner and outer housings, as well as on the outside surface of the outer housing. Methods of controlling and regulating a motor of the system to preserve the lifespan of the motor and maintain consistent airflow rates throughout the smoke evacuation system include varying a supply of electrical current to the motor so that it can operate at variable performance levels. Orifices are opened and closed in order to relieve resistance pressures within the airflow path due to clogging and blockages.
