Abstract
A device for inserting a myringotomy tube while permitting a twisting action to be imparted during the inserting step. A shaft of the device has a proximal and a distal end, and the proximal end is provided with a rotatable head which enables the deliberate rotation of the shaft. The distal end is adapted to releasably hold a myringotomy tube. A sleeve is provided and is adapted to movably hold a length of the shaft, while permitting the distal end of the shaft to be retracted into the sleeve. As the distal end is retracted into the sleeve, a pressure is exerted by the sleeve against a myringotomy tube held on the distal end, such that the tube is caused to be released from the distal end of the shaft. The invention also includes a provision for a handle fixedly attached to the sleeve and including a movable portion which can be caused to engage the rotatable head to move the head away from the sleeve, so that the distal end of the shaft is caused to be retracted into the sleeve.
