Abstract

A system for selectively actuating a heating current conductible from a bipolar generator to a surgical tool may comprise an actuator assembly having an output receptacle, an input plug, and an actuating component. The output receptacle may be configured to receive a complementary tool plug of the surgical tool. The input plug may be configured for mating with a generator receptacle receivable of the heating current from the bipolar generator. The generator receptacle may be complementary to the tool plug. The actuating component may have at least one of a switch and a lever arm and may be configured to communicate with the bipolar generator for selectively actuating the heating current to flow from the input plug to the output receptacle upon engagement of the switch or the lever arm.

Claims

1. A system for selectively actuating a heating current conductible from a generator to forceps, comprising:

an actuator assembly having a tool portion containing an output receptacle, and a generator portion containing an input plug and an actuating component, the actuator assembly further comprising a longitudinal axis defined by a line extending, when the forceps are connected to the output receptacle, from a proximal end of the forceps to a distal end between two elongated conducting members of the forceps;

the output receptacle configured to receive a complementary tool plug of the forceps;

the input plug configured for mating with a generator receptacle, the input plug configured to receive the heating current from the generator; and

the actuating component having a hard electrical switch and a lever arm, the lever arm having a first end and a second end, the first end of the lever arm adjacent to the generator portion of the actuator assembly, the second end of the lever arm extending towards a heating end of the forceps, a portion of the lever arm between the first end and the second end configured to engage the hard electrical switch upon displacement of the lever arm in a direction toward the longitudinal axis, and the actuating component being configured to communicate with the generator to selectively actuate the heating current to flow from the input plug to the output receptacle upon engagement of the hard electrical switch by the lever arm;

the hard electrical switch connecting the actuator assembly to the generator; and

a jumper cord connecting the tool portion of the actuator assembly to the generator portion of the actuator assembly, the jumper cord separating and providing conduction between the input plug and the output receptacle.

2. The system of claim 1, wherein:

the actuating component is configured to communicate with the generator to selectively actuate the heating current to flow with at least two of the following modes of operation of the surgical tool;

cutting, coagulation, or an off mode.

3. The system of claim 1, wherein:

the input plug and the complementary tool plug each comprise prongs and where the output receptacle and the generator receptacle each comprise at least two sockets complementary to the prongs.

4. The system of claim 1, wherein:

the hard electrical switch for actuating the heating current is configured as one of a push button, a slide switch, a toggle switch, a rotating shaft, a joystick, an electrostatic sensor, a piezoelectric sensor, a temperature switch, a rocker switch, a momentary switch, or a voice-activated switch.

5. The system of claim 1,

wherein the lever switch mechanism is configured to selectively actuate the heating current in response to the displacement of the lever arm by one of the following means:

mechanical actuation, electrical resistance, piezoelectric pressure, or electrostatic sensing.

6. The system of claim 1, further comprising:

the hard electrical switch configured to directly conduct the heating current from the input plug to the output receptacle upon the engagement of the hard electrical switch by the lever arm.

7. The system of claim 1, further comprising:

a microphone and a voice activation circuitry both included in the actuating component for selectively actuating the heating current.

8. The system of claim 1, wherein:

the lever arm is hingedly moveable to engage the hard electrical switch for selectively actuating the heating current.

9. A system for selectively actuating a heating current conductible from a generator to forceps, comprising:

two elongated conducting members extending from a base end of the forceps to a heating end of the forceps, a longitudinal axis extending from the base end to the heating end between the two elongated conducting members, the base end configured to receive the heating current from the generator through a power cord, the heating end for effectuating at least one of the following modes of operation of the forceps;

cutting or coagulation;

an actuator assembly having a tool portion comprising an output receptacle and a generator portion comprising both an input plug and an actuating component, the tool portion coupled to the generator portion by a jumper cord, the actuator assembly in operable electrical connection with the power cord and the two elongated conducting members, the actuator assembly configured within a base portion of the forceps nearer the base end;

an actuating component of the actuator assembly, the actuating component having a hard electrical switch and a lever arm, the lever arm having a first end and a second end, the first end of the lever arm adjacent to the generator portion of the actuator assembly, the second end of the lever arm extending towards the heating end of the forceps, a portion of the lever arm between the first end and the second end configured to engage the hard electrical switch upon displacement of the lever arm in a direction toward the longitudinal axis of the forceps, and the actuating component being configured to communicate with the generator to selectively actuate the heating current to flow from the generator to the heating end of the forceps upon engagement of the hard electrical switch by the lever arm; and

the hard electrical switch connecting the actuator assembly to the generator.

10. The system of claim 9, wherein:
