SUBMUCOUS BLADE SPECULUM. [PDF]
Journal of the American Medical Association, 1908 This speculum is designed to simplify, shorten and to facilitate generally submucous septal resection operations. A complete set consists of three pairs of blades of different sizes and one holder. One pair of blades is selected to suit the conditions of each individual case and fasten into the holder.
