Abstract
Abstract An improved tongue blade that may be used with frames of conventional design and forming part of a mouth gag, said blade having a handle portion that connects with a frame and a tongue-engaging portion that extends from said handle portion at an obtuse angle of between 120° and 135°, said blade providing an improved exposure of the tonsils for surgical removal. The improved exposure is uniquely attained in the lower pole for more complete removal of the tonsil, and easier access to bleeding vessels for quicker ligation of bleeders.
