ABSTRACT:
A forceps includes elongated arms with proximal and distal sections, the distal sections extending to the forceps tips. The arms are arranged and interconnected to enable appositional movement of the tips in order to enable a user to grip an object between the tips and thereby apply a component of force to the object that is generally perpendicular to the direction of such appositional movement. The proximal and distal sections of the first arm are connected with a break-away joint that is arranged to quickly reduce the amount of coupling when the component of force being applied to the object exceeds a predetermined level. Joints enabling pivotal or linear movement of the distal sections relative to the proximal sections may be provided, spring-biased mechanical break-away components or strain-gauge-based electrical break-away components may be used, and a human sensible signal indicating when the force exceeds the predetermined level may be produced.
