Abstract
An otoscopic instrument includes an instrument head attached to a handle and a speculum tip actuator mechanism for receiving, retaining and selectively ejecting an otoscopic speculum tip element. The tip actuator mechanism includes an actuator knob rotatably attached to the instrument head in which the instrument head includes annular securement slots sized for receiving external engagement features of a speculum tip element which are rotatably fitted into the slot(s). The actuator knob further includes a pin for displacing a secured speculum tip element from the securing slot upon rotation in a predetermined direction in order to eject the tip element.
