    摘要： A surgical instrument includes a housing having a shaft extending therefrom. The housing includes a nose having a neck and a base that defines a diameter greater than that of the neck. A rotation knob has a distal end defining a first aperture and a proximal end defining a second aperture, the apertures cooperating to define a lumen extending through the rotation knob that is configured to receive the shaft. The first aperture defines a diameter that generally approximates a diameter of the shaft. The rotation knob is transitionable between an at-rest position and a flexed position. In the flexed position, the second aperture is expanded to permit passage of the base of the nose into an interior of the rotation knob. In the at-rest position, the second aperture generally approximates the diameter of the neck to rotatably engage the rotation knob about the nose with the shaft extending therethrough.

    摘要： A surgical instrument includes a pair of jaw members moveable between a spaced-apart and an approximated position. A drive bar is translatable between a distal and a proximal position for moving the jaw members between the spaced-apart and approximated positions. A lever is moveable between an initial position and an actuated position for translating the drive bar between the distal and proximal positions. A sleeve disposed about the drive bar includes an annular track having a substantially radial segment(s) and a substantially longitudinal segment(s). A collar interdisposed between the sleeve and the drive bar includes a stop member(s) extending radially outwardly therefrom. The stop member(s) is engaged within the track and is translatable from a first position, wherein the stop member is positioned within the longitudinal segment, to a second position, wherein the stop member is engaged within the radial segment, to lock the lever in the actuated position.

    摘要： A forceps includes an end effector assembly having first and second jaw members. Each of the jaw members includes a proximal flange extending therefrom. Each of the proximal flanges defines a bifurcated configuration having first and second spaced-apart flange components. The first flange component of the first jaw member is configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling. The first flange component of the second jaw member is configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling different from the first protrusion-aperture coupling. One or both of the jaw members is pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween.
