An instrument for performing myringotomy operations consists of a device for incising, suctioning and grasping a tympanostomy tube (ISGTT) attached to a gripping handle. The ISGTT consists of a gripper and a pushing and suctioning member (PS) surrounded by an external tube. Peripheral fingers of the gripper press against the surface of the tubular segment of the tympanostomy tube for grasping. An incising blade disposed within the lumen of the PS is movable coaxially with the bore of the tympanostomy tube. Blade positioning selector located at the proximal end of the ISGTT provides for drawing and withdrawing the incising blade through the bore of the gripped tympanostomy tube. A lever pivotally attached to the griping handle is used to control grasping and releasing of the tympanostomy tube when properly placed.
