Proper retraction in phrenicectomies is the most important factor in the skilful and speedy completion of the operation through an incision of minimum length. Retractors in present use have been found unsatisfactory because of their width, thickness, narrowness, shortness or other disproportion.
In order to secure retractors to meet all needs in the operation, I have designed the instruments1 illustrated here and have found them entirely satisfactory. The instruments are made of such thinness as to encroach as little as possible on the space within the incision. The width is that which is considered most satisfactory for retraction in a small incision. The depth of the face of the retractor has been designed to meet the needs in the thick necked as well as the long, thin necked patient. The curve at the tip is such as to hold properly the retracted tissues without causing sharp pressure on an
