SURGICAL INSTRUMENT COMPRISING AN ELECTRODE

摘要

A surgical instrument can comprise a first electrode, a second electrode, and a retractable sheath. At least one of the electrodes can comprise an insulative jacket extending along the length thereof which can comprise a tissue stop for limiting the progression of the electrode into tissue. In various embodiments, a surgical instrument can comprise a first electrode, a second electrode, and a displaceable arc guard positioned between the electrodes. In certain embodiments, a surgical instrument can comprise an electrode including a flexible mesh configured to conform to the tissue against which it is positioned.

主权项

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; and a 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 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.
