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.

An endoscopic forceps includes a housing having a shaft attached thereto, the shaft including a pair of jaw members disposed at a distal end thereof. The forceps also includes a drive assembly disposed in the housing which moves the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for manipulating tissue. A pair of handles is operatively connected to the drive assembly and the handles are movable relative to the housing to actuate the drive assembly to move the jaw members. Each of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue. The forceps also includes a first switch disposed on the housing which is activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue in a monopolar fashion. A second switch is disposed on the housing and is activatable to selectively deliver energy of a first electrical potential to one jaw member and selectively deliver energy of a second electrical potential to the other jaw member for treating tissue in a bipolar fashion.

An endoscopic bipolar forceps is provided. The forceps includes a housing, a shaft, a drive assembly, a handle assembly and a slide activated cutting assembly. The shaft is affixed to the housing and comprises an end effector assembly comprising two jaw members at its distal end. The drive assembly is configured to move the end effector assembly. The handle assembly is in mechanical cooperation with the drive assembly. The slide-activated cutting assembly is disposed at least partially within the housing and move a knife rod comprising a knife blade at its distal end to cut tissue along a tissue seal. A source of electrosurgical energy is adapted to connect to each jaw member to enable them to conduct energy through tissue to affect a tissue seal.

The present disclosure relates to a surgical instrument which includes a shaft having a proximal end and a distal end and a housing connected to the proximal end of the shaft. The instrument may further include an actuation assembly having a first lever and a second lever, each pivotally connected to the housing. An end effector assembly is operatively connected to the distal end of the shaft and includes a pair of opposing jaw members. The instrument may further include a drive rod slidably disposed within the shaft and connected to the actuation assembly, the drive rod being operable by the actuation assembly to actuate the opposing jaw members between open and closed positions. A latching mechanism may be provided which is operatively associated with the actuation assembly and drive rod for maintaining the jaw members in the closed position.

A removable handswitch and electrode assembly for use with a forceps having opposing end effectors and a handle for effecting relative movement of the end effectors with respect to one another includes a housing having at least one portion which removably engages at least a portion of a mechanical forceps and a handswitch assembly disposed on the housing. A pair of electrodes is included which removably engage a distal end of the mechanical forceps such that the electrodes reside in opposing relation to one another. At least one electrode is adapted to connect to an electrosurgical generator through the handswitch assembly. At least one stop member is operatively associated with the electrodes and controls the distance between the opposing electrodes to affect a tissue seal.

A hemostat includes a housing which has a shaft extending distally therefrom. The shaft has an end effector assembly distally attached thereto. The hemostat also includes a pair of first and second handles which are connected to the housing. The first and second handles are operatively connected to the end effector assembly. At least one of the first and second handles are moveable relative to the other handle to effectively actuate the end effector assembly. The hemostat further includes a magnetic closure mechanism which has a first magnet connected to the first handle and a second magnet connected to the second handle. The first and second magnets each have a magnetic potential and are securely engageable with one another when the handles are moved from a first spaced configuration to a second closer position.
