US Patent 8968358 Blunt tissue dissection surgical instrument jaw designs

A forceps for use in surgery for dissecting tissue includes a pair of jaw members movable from an open position in spaced relation relative to one another to a closed position. The jaw members each have an outer housing extending along the length thereof to a distal end of the jaw members. The outer housing of one of the jaw members includes a textured surface at a distal end configured to interface with and dissect tissue during the movement of the jaw members from the closed to open positions. A dissecting tip may be selectively extendable from a channel defined in one of the jaw members to engage and separate tissue when in the extended position.
