Abstract
Abstract Forceps, either of the tweezer type or scissors-like type, in which cross-beaking of the jaws is resisted by the presence of a flexible connector attached between the forceps arms adjacent to the jaws. This connector is bowed away from the jaws and extends sufficiently in a plane at right angles to the plane of movement of the arms at the points of attachment to the arms to resist torsion during the operation of the forceps.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
Forceps comprising a. a pair of arms each having a first and a second end, b. a jaw located at the first end of each arm, c. an intermediate section joining the second ends of each arm remote from said jaws for permitting relative movement of said arms in a plane passing through the length of each arm, and d. flexible connector means attached between the two said arms at points adjacent said jaws, being bowed away from said jaws toward said intermediate section and moving in the space between said arms about said points of attachment.
Claim 2
Dependent Claim
