Modular electrosurgical adaptors and multi function active shafts for use in electrosurgical instruments

A forceps system connectable to a power source, said system comprising:

• a handle body;
• a surgical device, a portion of the surgical device being removably disposed within the handle body, another portion of the surgical device being operably associated with a pair of jaw members;
• and
• at least one handle member pivotally attached to the handle body for articulating the jaw members on the surgical device;
• and wherein
• the surgical device includes
• an adaptor body engagable to the handle body, a portion of the adaptor body including an area defining a hollow passage,
• a compound shaft assembly disposed at least partially within the hollow passage of the adaptor body and operatively connected to the jaw members and the at least one handle member,
• the adaptor body defining a groove thereon and extending therearound and an aperture extending from the groove,
• an adaptor body spring contact disposed within the aperture and thus removable from the handle body as the surgical devices is removed from the handle body and electrically connected to the compound shaft assembly for conducting electrical current from the power source to the compound shaft assembly when disposed within the handle body, and
• a contact ring disposed within the groove and coupled to the adaptor body spring contact for compressing the adaptor body spring contact and conducting electrical current therethrough.
