Abstract
Abstract A pliers-type of surgical instrument is provided with narrow jaws adapted to enter human nostrils on both sides of the septum. The mutually opposed faces of the jaws have pyramided teeth and recesses which interfit when the jaws come together. This morselizes and masticates the cartilage of the septum simultaneously on both sides. When the cartilage is thus morselized, the ELASTIN or BRAIN of the cartilage which is responsible for causing the cartilage to return to its original shape maintaining its architectural form is cut, permitting its reconstitution into a new shape which it thereafter maintains.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
126 words
A surgical instrument having a pair of elongated narrow jaws hinged together and adapted to be inserted in nostrils of a human nose, said jaws having on their mutually opposed faces areas of points and hollows, the points and hollows on one jaw interfitting with the hollows and points of the other jaw when the jaws are brought together, each said area having a checkerboard pattern of pyramidal points and pyramidal hollows, serving to cut cartilage and the elastin within the matrix into small morsels leaving the chondrocytes at the margins intact, some areas of the cartilage being compressed, these factors resulting in the elimination of the stress forces of tension and compression normally present in cartilage and permitting the cartilage shape to be permanently altered.
