Abstract
An electrosurgical apparatus including an automatic applicator identifier used to communicate between an applicator and a generator unit, automatically presetting various values, is provided. These values may be stored in a one-wire serial memory storage device located in the applicator or connector coupled to the applicator. Communication from the applicator to the generator unit of these values is affected by a one-wire serial communication protocol. This information can be transferred over a direct electrical path through the connector that attaches that applicator to the generator unit, or instead by a wireless link.
Claims29
An electrosurgical apparatus comprising:
- a housing having a passage extending therethrough, the housing having a proximal end and a distal end;
- an electrically conducting tube having a proximal end and a distal end, the electrically conducting tube being disposed in the passage of the housing;
- an insulating outer tube having a proximal end and a distal end, the outer tube disposed around the electrically conducting tube with the proximal end of the outer tube coupled to the distal end of the housing, the electrically conducting tube being movable along a longitudinal axis of the housing and outer tube;
- an electrode coupled to the distal end of the electrically conducting tube, wherein at least the housing, electrically conducting tube, the insulating outer tube, and the electrode comprise an applicator, and
- a connector configured for coupling the applicator to an electrosurgical generator, the connector including a memory configured to store parameters associated with the applicator, wherein at least a first parameter of the stored parameters is a type of gas associated with the applicator and the connector is configured to communicate the type of gas associated with the applicator to the electrosurgical generator, wherein the connector is further configured to receive a gas from the electrosurgical generator and provide the received gas to the electrically conducting tube when the type of gas associated with the applicator matches the gas provided by the electrosurgical generator.

An electrosurgical apparatus comprising:
- an electrosurgical generator coupled to an electrical power supply and configured to generate electrosurgical energy, the electrosurgical generator including a flow controller that supplies a gas to an applicator;
- the applicator including:
- a housing having a passage extending therethrough, the housing having a proximal end and a distal end;
- an electrically conducting tube having a proximal end and a distal end, the electrically conducting tube being disposed in the passage of the housing;
- an insulating outer tube having a proximal end and a distal end, the outer tube disposed around the electrically conducting tube with the proximal end of the outer tube coupled to the distal end of the housing, the electrically conducting tube being movable along a longitudinal axis of the housing and outer tube;
- an electrode coupled to the distal end of the electrically conducting tube;
- and
- a connector configured for coupling the applicator to the electrosurgical generator, the connector including a memory configured to store parameters associated with the applicator, wherein at least a first parameter of the stored parameters is a type of gas associated with the applicator and the connector is configured to communicate the type of gas associated with the applicator to the electrosurgical generator, wherein if the type of gas associated with the applicator matches a gas to be supplied by the flow controller, the flow controller supplies the gas to the applicator.

An electrosurgical apparatus comprising:
- an electrosurgical generator coupled to an electrical power supply and configured to generate electrosurgical energy;
- and
- an applicator that supplies the electrosurgical energy to a surgical site including at least a connector configured for coupling the applicator to the electrosurgical generator, the connector including a memory configured to store parameters associated with the applicator, wherein at least a first parameter of the stored parameters is a type of gas associated with the applicator;
- and
- a gas discriminator coupled to the electrosurgical generator, the gas discriminator configured to determine the type of gas being supplied to the applicator, compare the determined type of gas being supplied to the applicator with the type of gas associated with the applicator, and prevent further operation of at least one of the applicator and electrosurgical generator if the discriminator determines the type of gas associated with the applicator is different than the type of gas being supplied to the applicator.
