A surgical system, comprising: a surgical forceps including an end effector assembly including a pair of jaw members (18a, 18b) each defining a tissue-contacting surface, the jaw members movable from a spaced-apart position to an approximated position; an adapter releasably engageable with the end effector assembly, the adapter including a pair of jaw bodies and an interconnect band coupling the jaw bodies with one another, each jaw body including a support plate configured for positioning on the tissue-contacting surface of one of the jaw members, and a chuck; and a surgical clip releasably engageable with the adapter, the surgical clip including a pair of legs and a backspan interconnecting the legs, each leg configured for receipt at least partially within the chuck of one of the jaw bodies of the adapter, wherein, with the surgical clip engaged with the adapter and the adapter engaged with the end effector assembly, the jaw members are configured to move from the spaced-apart position towards the approximated position to move the jaw bodies towards one another to, in turn, urge the legs of the surgical clip towards one another to form the surgical clip, wherein the surgical forceps further includes a knife selectively translatable relative to the jaw members between a retracted position and an extended position, wherein the knife extends at least partially through a knife channel defined within and extending longitudinally through at least one of the tissue-contacting surfaces, and wherein the at least one of the jaw bodies of the adapter includes a fin configured for receipt within the knife channel of one of the jaw members. a surgical forceps including an end effector assembly including a pair of jaw members (18a, 18b) each defining a tissue-contacting surface, the jaw members movable from a spaced-apart position to an approximated position; an adapter releasably engageable with the end effector assembly, the adapter including a pair of jaw bodies and an interconnect band coupling the jaw bodies with one another, each jaw body including a support plate configured for positioning on the tissue-contacting surface of one of the jaw members, and a chuck; and a surgical clip releasably engageable with the adapter, the surgical clip including a pair of legs and a backspan interconnecting the legs, each leg configured for receipt at least partially within the chuck of one of the jaw bodies of the adapter, wherein, with the surgical clip engaged with the adapter and the adapter engaged with the end effector assembly, the jaw members are configured to move from the spaced-apart position towards the approximated position to move the jaw bodies towards one another to, in turn, urge the legs of the surgical clip towards one another to form the surgical clip, wherein the surgical forceps further includes a knife selectively translatable relative to the jaw members between a retracted position and an extended position, wherein the knife extends at least partially through a knife channel defined within and extending longitudinally through at least one of the tissue-contacting surfaces, and wherein the at least one of the jaw bodies of the adapter includes a fin configured for receipt within the knife channel of one of the jaw members.
