Abstract
Forceps include a body, a surgical device, and a pair of handles. The surgical device is removably disposed within the body. The handles are pivotally attached to the handle body for articulating jaws on the surgical device, or grasping the forceps. The forceps accept monopolar, bipolar, or both monopolar and bipolar surgical devices. Wires are disposed within the surgical device for performing various types of electro-surgery. Additional wires are provided within the surgical device for providing the user with the ability to monitor various aspects of the surgical procedure. Spring contacts touch rings surrounding the surgical device for maintaining electrical contact with the surgical device while allowing the surgical device to rotate within the body.
