Abstract
A bipolar forceps may include a first forceps arm having a first forceps arm aperture, a first forceps jaw, and a first forceps arm conductor tip; a second forceps arm having a second forceps arm aperture, a second forceps jaw, and a second forceps arm conductor tip; and an input conductor isolation mechanism having a first forceps arm housing and a second forceps arm housing. The first forceps arm conductor tip may be configured to conduct current only at a medial portion of the first forceps arm. Illustratively, the second forceps arm conductor tip may be configured to conduct current only at a medial portion of the second forceps arm.
