Abstract
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.
Claims32
An electrosurgical wave generator for performing electrically driven medical procedures, the electrosurgical wave generator comprising:
- a housing;
- a control unit disposed within the housing and that is configured to generate and control output signals to a monopolar electrosurgical instrument or a bipolar electrosurgical instrument;
- a first electrical connection associated with the housing and configured to have the monopolar electrosurgical instrument selectively connected thereto;
- a second electrical connection associated with the housing and configured to have the bipolar electrosurgical instrument selectively connected thereto;
- and
- a third electrical connection associated with the housing and configured to have a return electrode selectively connected thereto,
- wherein an arrangement of the first, second, and third electrical connections relative to one another is configured to:
- enable simultaneous connection of the monopolar electrosurgical instrument to the first electrical connection and the return electrode to the third electrical connection;
- and
- prevent connection of the monopolar electrosurgical instrument to the first electrical connection and the return electrode to the third electrical connection when the bipolar electro surgical instrument is connected to the second electrical connection.
An electrosurgical wave generator for performing electrically driven medical procedures, the electrosurgical wave generator comprising:

- a control unit disposed within the housing and that is configured to generate and control output signals to a monopolar electrosurgical instrument or a bipolar electrosurgical instrument;
- a first electrical connection associated with the housing and configured to have the monopolar electrosurgical instrument selectively connected thereto;
- a second electrical connection associated with the housing and configured to have the bipolar electrosurgical instrument selectively connected thereto, the second electrical connection comprising first and second receptacles;
- and
- a third electrical connection associated with the housing and configured to have a return electrode selectively connected thereto, the third electrical connection being positioned between the first and second receptacles of the second electrical connection,
- wherein the positioning of the second electrical connection between the first and second receptacles of the third electrical connection prevents the simultaneous connection of the return electrode to the third electrical connection and the bipolar electrosurgical instrument to the second electrical connection.
