More Information
Summary:An electrosurgical forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The forceps also includes a switch assembly that includes a supporting member, a flexible membrane circuit having snap dome switch contacts operably fixed thereto, and ergonomically-contoured keytops. The switch assembly provides at least one monopolar activation switch, and a bipolar activation switch. The forceps also include a drive mechanism which causes the jaw members to move relative to one another for manipulating tissue. A monopolar safety switch is incorporated into the switch assembly which cooperates with the drive mechanism to inhibit the monopolar activation switch when the jaw members are in an open position.
