Surgical device having changeable elements

An electrosurgical device kit comprising:

• an elongate first member with a first projection;
• an elongate second member disposed adjacent to the first member, the second member having a second projection and being at least movably coupled to the first member;
• the first and second projections being parallel with their respective elongate members,
• a first electrode head;
• a second electrode head;
• and
• a third electrode head,
• wherein each of the first electrode head and the second electrode head is removably attachable independently of each other to the first member, so that either the first electrode head or the second electrode head remains attached to the first member when the other electrode head is removed from the first member and the third electrode head remains attached to the second member, and wherein the third electrode head is removably attachable independently of the first electrode head and the second electrode head to the second member, so that the first electrode head or the second electrode head remains attached to the first member,
• wherein the first, second, and third electrode heads are configured to apply a current to a tissue, the first and second electrode heads being non-identical, and
• wherein each of the first electrode head, the second electrode head, and the third electrode head includes a cavity configured to attach the respective electrode head to the first projection or the second projection.
