Patent ID: 8679098

Claim:
A surgical instrument, comprising: a housing having a shaft extending distally therefrom and defining a longitudinal axis, the housing including a nose disposed at a distal end thereof, the nose including a neck extending distally from the housing and a base disposed at a distal end of the neck, the base defining a diameter greater than a diameter of the neck; and a rotation knob having a distal end defining a first aperture and a proximal end defining at least one second aperture, the first and second apertures cooperating to define a lumen extending longitudinally through the rotation knob that is configured to receive the shaft, the rotation knob flexible between an at-rest position and a flexed position, wherein, in the flexed position, the diameter of the second aperture is expanded from a first diameter to a second, larger diameter to permit passage of the base of the nose through the second aperture and into an interior of the rotation knob, and wherein, in the at-rest position, the second aperture defines the first diameter to rotatably engage the proximal end of the rotation knob about the nose with the shaft extending through the lumen of the rotation knob.
