  • Patent number: 9775610
    Abstract: A surgical device includes a jaw assembly, an articulating assembly and a drive shaft. The jaw assembly includes first and second jaws. The articulating assembly is removably coupled to a proximal end of the jaw assembly and includes a distal joint member, a proximal joint member, and a pivot pin. The pivot pin is fixedly coupled to the distal joint member and is rotatably coupled to the proximal joint member. The jaw assembly and the distal joint member together define a first longitudinal axis. The proximal joint member defines a second longitudinal axis. The drive shaft includes a gear element that is meshingly engaged with a pivoting gear element that is fixedly coupled to the pivot pin. Longitudinal movement of the first drive shaft pivots the jaw assembly relative to the proximal joint member about a pivot axis defined by the pivot pin.

  • Patent number: 9636128
    Abstract: A safety handle assembly for use with a surgical instrument having an operative distal end portion is disclosed. The handle assembly includes a handle housing and a drive element movably mounted within the handle housing and connected to an associated operative distal end portion. A drive assembly is positioned within the handle housing and is engageable with the drive element to move the drive element within the handle housing. An actuator is movably mounted on the handle housing and an adjustable force-limiting mechanism is interposed between the drive assembly and the actuator. A force-limiting mechanism releasably connects the actuator to the drive assembly. The force-limiting mechanism is adjustable to preset the force at which the actuator separates or breaks away from the drive assembly.

  • Publication number: 20170020526
    Abstract: A loading unit includes a shell assembly and a locking band. The shell assembly has a proximally extending annular body. The annular body defines two hook openings that oppose one another, a lug opening positioned between the hook openings, and a central passage for receiving a portion of a surgical instrument. The locking band has an arced body with two ends, a retention hook positioned adjacent each end of the body and extending from the inner surface of the body. Each of the retention hooks is disposed within a respective one of the hook opening to retain a respective one of the ends of the locking band to the annular body. The lug is disposable through the lug opening into the central passage to secure the loading unit to a surgical instrument.
