    摘要： An endoscopic forceps is provided and includes a housing having a handle assembly including a movable handle having a mechanical interface disposed thereon. An end effector assembly connected to a distal end of the shaft includes a pair of first and second jaw members movable relative to one another from an open to a clamping position. A drive assembly includes a resilient member. A lock assembly is pivotably coupled to the housing and in operative communication with the movable handle. The lock assembly is movable with the handle assembly. The mechanical interface moves along the lock assembly when the movable handle is moved proximally causing the lock assembly to rotate about the pivot point and into communication with the resilient member such that the resilient member is prevented from moving distally against the bias provided therefrom such that the first and second jaw members remain in the clamping position.

    摘要： A forceps includes a housing having a shaft extending therefrom. The shaft has an end effector assembly that defines a longitudinal axis therethrough. The end effector assembly includes first and second jaw members disposed in opposed relation and moveable from a first, open position to a second, closed position for grasping tissue therebetween and a knife. One or more jaw members include knife blade channels defined therein. Each knife blade channel includes a polygonal longitudinal cross-section defined therein. The knife includes a knife edge and a knife base. The knife base includes a corresponding polygonal longitudinal cross-section. The knife is configured to translate through the knife blade channels and the knife base is configured to slidingly engage the knife base channel having the polygonal cross section upon translation of the knife. In embodiments, the knife blade channel and the knife base have a T-shaped longitudinal cross-section.

    摘要： An endoscopic forceps includes a housing having a shaft attached thereto that supports a pair of jaws disposed at a distal end thereof. A drive assembly having a drive shaft with a proximal end is operable to move the jaws relative to one another from an open to closed positions. A knife assembly is operable to advance a knife through tissue disposed between the jaws and includes a flange disposed thereon. A knife lockout is included that has a flange configured to engage the proximal end of the drive shaft and a lockout arm configured to engage the flange of the knife assembly to prevent movement thereof. Movement of the jaws to the closed position causes the proximal end of the drive shaft to engage the flange on the lockout which causes the lockout arm to disengage the flange on the knife assembly to permit advancement of the knife.

    摘要： A surgical instrument comprises a handle assembly including an actuator mounted for manipulation through an actuation stroke. An elongate shaft extends distally from the handle assembly and defines a longitudinal axis. A reciprocating member extends at least partially through the elongate shaft, and is mounted for longitudinal motion through the elongate shaft in response to manipulation of the actuator through the actuation stroke. A drive mechanism includes a first rotating component coupled to the actuator about a first circumference to induce rotational motion in the first rotating component. A second rotating component is coupled to the first rotating component such that rotational motion in the first rotating component induces rotational motion in the second rotating component. The second rotating component is coupled to the reciprocating member about a second circumference such that rotational motion of the second rotating component induces longitudinal motion in the reciprocating member. The second circumference is greater than the first circumference.

    摘要： A flex circuit optical sensor has an integrated Faraday shield. A conductive trace layer disposed on a substrate is used to form a conductive grid which shields the face of a photodetector. A conductive ink layer is formed on a substrate side opposite the trace layer. The back and sides of the detector are shielded by flex circuit flaps that have the conductive ink layer but substantially exclude the trace layer so as to fold over and closely adhere to the detector body. The shielded substrate flaps advantageously eliminate a separate detector shield, which is typically fabricated with an etched copper part that must be attached to a flex circuit before mounting the detector.
