Abstract: A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot.

Abstract: A surgical device employs a longevity circuit for preventing operation after a specified time based on safe use expectations. The surgical device delivers a therapy signal via a handpiece having electrodes in proximity to the surgical site. The therapy signal is a high frequency electrical signal delivered from a generator coupled to the handpiece, and activated by a control signal. A therapy circuit established by coupling the handpiece and generator delivers the therapy signal, and is monitored for activation based on a time since a first activation, a number of activations, or an aggregate time of activated intervals. A usage limit defines the activation lifespan, and is employed for monitoring either the therapy circuit or the control circuit, to determine a usage history. Following expiration of a safe usage limit, a longevity circuit in the handpiece disables the handpiece for successive uses, and is independent of a connection to a particular generator.
