Adapters, systems incorporating the same, and methods for providing an electrosurgical forceps with clip-applying functionality

Adapters for use with surgical systems including a surgical forceps, and a surgical clip; and methods for providing clip-applying functionality are disclosed. The adapter is releasably engagable with the end effector assembly of the surgical forceps. The surgical clip is releasably engagable with the adapter. With the surgical clip engaged with the adapter and the adapter engaged with the end effector assembly, the jaw members of the end effector assembly are configured to move from the spaced-apart position towards the approximated position to move the jaw bodies of the adapter towards one another to, in turn, urge the legs of the surgical clip towards one another to form the surgical clip.
