    Abstract: A forceps includes first and second shaft members each having a jaw member disposed at a distal end thereof. One (or both) of the first and second jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. The first jaw member includes a jaw frame fixedly engaged to the first shaft member and a disposable jaw housing releasably engageable with the jaw frame. The disposable jaw housing includes a knife assembly disposed therein. The knife assembly includes a knife blade biased toward an initial position, wherein the knife blade is disposed within the jaw housing. The knife blade is moveable between the initial position and an extended position, wherein the knife blade extends at least partially from the jaw housing to cut tissue grasped between the first and second jaw members.

    Abstract: A surgical instrument is provided. The surgical instrument includes a housing. A movable handle is coupled to the housing and is configured to approximate a pair of jaw members toward and away from one another. A latch mechanism operably couples to the movable handle and includes one or more mechanical interfaces configured to selectively engage a corresponding mechanical interface disposed within the housing to lock and unlock the jaw members in an approximated configuration. When the movable handle is in a jammed position, the mechanical interface(s) of the latch mechanism is/are configured to deform and separate from the corresponding mechanical interface disposed within the housing when the movable handle is moved from the jammed position.

    Abstract: A connection mechanism and manufacturing method for a surgical instrument includes an inner shaft member that extends at least partially through an elongated shaft member of the instrument and defines proximal and distal ends and is selectively movable in a longitudinal direction with respect to the elongated shaft member and includes at least one aperture that extends partially along the longitudinal direction and disposed distally from the proximal end. The inner shaft member enables a drive collar member to slide on the inner shaft member and reciprocate along the longitudinal direction. A drive collar stop member slides on the inner shaft member and moves along the longitudinal direction. The drive collar stop member then moves in a direction relative to the longitudinal axis to engage the aperture and limit further longitudinal motion of the drive collar member. An inner shaft stop member limits movement of the inner shaft.

    Abstract: A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft. The end effector includes upper and lower jaw members pivotally coupled to the distal portion of the elongated shaft about a pivot axis and including a pair of laterally spaced flanges. The pairs of flanges of the jaw members are arranged in an offset configuration such that one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.
