A surgical instrument configured to deliver electrical energy to the tissue of a patient is disclosed. The surgical instrument comprises a frame, a first electrode, a second electrode, and a guard movable between a first position and a second position. The surgical instrument further comprises a spring positioned intermediate the guard and the frame. The spring is configured to bias the guard into the first position. When the guard is in the first position, a distal end of the guard is positioned at least flush with distal ends of the first electrode and the second electrode, which prevents current from arcing between the first electrode and the second electrode. When the guard is in the second position, the distal end of the guard is in contact with the tissue, which prevents current from arcing between the first electrode and the second electrode without passing through the tissue.

1. A surgical instrument configured to deliver electrical energy to the tissue of a patient, comprising: a frame;a first electrode, comprising: an elongate portion defined along a first axis; anda distal portion configured to contact the tissue;a second electrode, comprising: an elongate portion defined along a second axis; anda distal portion configured to contact the tissue;a guard movable between a first position and a second position, wherein said guard is comprised of an electrically insulative material; anda spring positioned intermediate said guard and said frame, wherein said guard is positioned intermediate said distal portion of said first electrode and said distal portion of said second electrode when said guard is in said first position, wherein said spring is configured to bias said guard into said first position, and wherein said guard is retracted proximally with respect to said first electrode and said second electrode and not positioned intermediate said distal portion of said first electrode and said distal portion of said second electrode when said guard is in said second position,wherein when said guard is in said first position, a distal end of said guard is positioned at least flush with distal ends of said first electrode and said second electrode, which prevents current from arcing between said first electrode and said second electrode when said guard is in said first position; andwherein when said guard is in said second position, said distal end of said guard is in contact with the tissue, which prevents current from arcing between said first electrode and said second electrode without passing through the tissue when said guard is in said second position. 2. The surgical instrument of claim 1, wherein said guard is configured to move from said first position to said second position when said first electrode and said second electrode are inserted into the tissue. 3. The surgical instrument of claim 1, wherein said guard is configured to move from said first position to said second position when said guard contacts the tissue. 4. A surgical instrument configured to deliver electrical energy to the tissue of a patient, comprising: a housing;a first electrode, comprising: a first elongate portion defined along a first axis; anda first distal portion;a second electrode, comprising: a second elongate portion defined along a second axis; anda second distal portion;a guard comprising a distal end, wherein said guard is positioned intermediate said first electrode and said second electrode; anda resilient member positioned intermediate said guard and said housing, wherein said guard is movable between a distal position and a proximal position, wherein said resilient member is configured to bias said guard into said distal position,wherein when said guard is in said distal position, said distal end of said guard is positioned at least flush with distal ends of said first electrode and said second electrode, which prevents current from arcing between said first electrode and said second electrode when said guard is in said distal position, andwherein when said guard is in said proximal position, said distal end of said guard is in contact with the tissue, which prevents current from arcing between said first electrode and said second electrode without passing through the tissue when said guard is in said proximal position. 5. The surgical instrument of claim 4, wherein said guard is comprised of an electrically insulative material. 6. The surgical instrument of claim 4, wherein said guard is configured to move from said distal position to said proximal position when said first electrode and said second electrode are inserted into the tissue. 7. The surgical instrument of claim 4, wherein said guard is configured to move from said distal position to said proximal position when said guard contacts the tissue. 8. The surgical instrument of claim 4, wherein said distal end of said guard extends beyond said first distal portion and said second distal portion when said guard is in said distal position. 9. A surgical instrument configured to deliver electrical energy to the tissue of a patient, comprising: a sheath;a first electrode, comprising: a first elongate portion defined along a first axis; anda first distal end portion configured to contact the tissue;a second electrode, comprising: a second elongate portion defined along a second axis; anda second distal end portion configured to contact the tissue;a guard comprising a distal end, wherein said guard is movable between a first position and a second position; anda biasing means positioned intermediate said guard and said sheath, wherein said guard is positioned intermediate said first electrode and said second electrode, wherein said biasing means is configured to bias said guard into said first position, and wherein said distal end of said guard extends between said first distal end portion and said second distal end portion when said guard is in said first position,wherein said guard is retracted proximally with respect to said first electrode and said second electrode when said guard is in said second position,wherein when said guard is in said first position, said distal end of said guard is positioned at least flush with distal ends of said first electrode and said second electrode, which prevents current from arcing between said first electrode and said second electrode when said guard is in said first position; andwherein when said guard is in said second position, said distal end of said guard is in contact with the tissue, which prevents current from arcing between said first electrode and said second electrode without passing through the tissue when said guard is in said second position. 10. The surgical instrument of claim 9, wherein said guard is comprised of an electrically insulative material. 11. The surgical instrument of claim 9, wherein said guard is configured to move from said first position to said second position when said first electrode and said second electrode are inserted into the tissue. 12. The surgical instrument of claim 9, wherein said guard is configured to move from said first position to said second position when said guard contacts the tissue. 13. The surgical instrument of claim 9, wherein said distal end of said guard extends beyond said first distal end portion and said second distal end portion when said guard is in said first position. 14. The surgical instrument of claim 9, wherein said distal end of said guard is positioned flush with said first distal end portion and said second distal end portion.
