ABSTRACT:
Forceps of the alligator jaw type, that can be held by a surgeon in a reversed backhand grip while observing the movable jaw during microlumbar discectomy, comprise three linkage devices for resisting twisting forces that tend to separate the sliding arms during removal of gristle. These devices are a slide slot within the rigid arm member in combination with a butt portion of the slideable arm member, a pivot slot within the slideable arm member in combination with a lug portion of the pivotable handle member, and a pin portion of the locking pin member in combination with aligned holes in the slideable arm member and pivotable arm member. The third device simultaneously keeps the forceps in assembled relationship; yet its removal instantly permits disassembly thereof. These three devices are combined within a very compact part of the instrument.
Usage of the forceps in a reversed backhand grip enables a surgeon to rest the heel of his hand upon the patient's back and exert a very light touch within the two-millimeter opening so that a plunge beyond the anterior side of the disc can be obviated, the arms can be inserted at a flatter angle beneath the nerves for pulling out gristle, and the operating time can be reduced to about 30 minutes.
