Abstract

A momentary rocker switch for use with a surgical device is provided. The momentary rocker switch includes a switch assembly and a connection assembly. The switch assembly includes a lever, a bipolar detent, a monopolar detent and a pivot collar. The lever has a bipolar activation portion and a monopolar activation portion. The connection assembly is in mechanical cooperation with the switch assembly and includes a bipolar switch connection, a monopolar switch connection and a pivot pin. The pivot pin is configured to pivotally engage the pivot collar of the switch assembly, thus enabling the lever to toggle from a first position to at least a second position. Upon depression of the bipolar activation portion of the lever, the bipolar detent contacts the bipolar switch connection. Upon depression of the monopolar activation portion of the lever, the monopolar detent contacts the monopolar switch connection.

Claims

1. A momentary rocker switch for use with a surgical device, the momentary rocker switch comprising:

a switch assembly, including;

a lever having a bipolar activation portion, a monopolar activation portion, a ventral side and a dorsal side;

a bipolar detent disposed on the bipolar activation portion and on the ventral side of the lever;

a monopolar detent disposed on the monopolar activation portion and on the ventral side of the lever;

a pivot collar disposed on the ventral side of the lever between the bipolar activation portion and the monopolar activation portion; and

a connection assembly in mechanical cooperation with the switch assembly, including;

a bipolar switch connection;

a monopolar switch connection; and

a pivot pin disposed between the bipolar switch connection and the monopolar switch connection, the pivot pin being dimensioned and configured to pivotally engage the pivot collar of the switch assembly, the engagement between the pivot pin and the pivot collar enables the lever to toggle from a first position to at least a second position;

wherein, upon depression of the bipolar activation portion of the lever, the bipolar detent contacts the bipolar switch connection and upon depression of the monopolar activation portion of the lever, the monopolar detent contacts the monopolar switch connection.

2. The momentary rocker switch according to claim 1, further comprising a plurality of protrusions disposed on the dorsal side of the lever on at least one of the bipolar activation portion and the monopolar activation portion.

3. The momentary rocker switch according to claim 1, further comprising indicia disposed on the dorsal side of the lever on at least one of the bipolar activation portion and the monopolar activation portion.

4. The momentary rocker switch according to claim 3, wherein the indicia comprises at least one of a letter and a logo.

5. The momentary rocker switch according to claim 1, wherein depression of the bipolar activation portion of the lever activates bipolar electrosurgical energy.

6. The momentary rocker switch according to claim 1, wherein depression of the monopolar activation portion of the lever activates monopolar electrosurgical energy.

7. The momentary rocker switch according to claim 1, wherein the lever is pivotable between at least a bipolar position and a monopolar position, such that the bipolar activation portion of the lever and the monopolar portion of the lever cannot be depressed simultaneously.

8. The momentary rocker switch according to claim 7, wherein the lever is further pivotable to an off position, the off position being between the bipolar position and the monopolar position.

9. The momentary rocker switch according to claim 8, further comprising at least one spring which biases the lever towards the off position.

10. The momentary rocker switch according to claim 1, wherein the connection assembly further comprises a printed circuit board.

11. The momentary rocker switch according to claim 1, wherein the connection assembly further comprises a bipolar printed circuit board.

12. The momentary rocker switch according to claim 1, wherein the connection assembly further comprises a monopolar printed circuit board.

13. The momentary rocker switch according to claim 1, wherein the momentary rocker switch is mounted onto a surgical device, the portion of the momentary rocker switch that is farthest from a surface of the surgical device is defined as the apex.

14. The momentary rocker switch according to claim 1, further comprising a safety device at least partially covering one of the bipolar activation portion of the lever and the monopolar activation portion of the lever, the safety device at least partially obstructing the activation portion of the lever.

15. The momentary rocker switch according to claim 1, further comprising a projection at least partially covering one of the bipolar activation portion of the lever and the monopolar activation portion of the lever, the projection at least partially obstructing the activation portion of the lever.

16. A forceps comprising a momentary rocker switch, the momentary rocker switch comprising:

a switch assembly, including;

a lever having a bipolar activation portion and a monopolar activation portion; and

a connection assembly in mechanical cooperation with the switch assembly, including;

a bipolar switch connection;

a monopolar switch connection; and

a pivot pin disposed between the bipolar switch connection and the monopolar switch connection, the pivot pin dimensioned and configured to pivotally engage a portion of the switch assembly, the engagement between the pivot pin and the portion of the switch assembly enable the lever to toggle from a first position to at least a second position;

wherein, upon depression of the bipolar activation portion of the lever, the bipolar activation portion contacts the bipolar switch connection and, upon depression of the monopolar activation portion of the lever, the monopolar activation portion contacts the monopolar switch connection.
