Abstract: Certain embodiments described herein provide a surgical ear speculum comprising a tubular body having an anterior end, a posterior end, and a first length from the anterior end to the posterior end. The tubular body has an inner layer, an outer layer, and a middle layer between the inner layer and the outer layer. The inner layer, the outer layer, and the middle layer are peripherally disposed around a central cavity of the surgical ear speculum. The central cavity extends from the anterior end of the surgical ear speculum to the posterior end of the surgical ear speculum. The inner layer comprises a first membrane, and the outer layer comprises a second membrane. The middle layer comprises an expandable and contractible wire mesh disposed between the first membrane and the second membrane.

Abstract: The present disclosure generally relates to a trans-eustachian multi-function system. The trans-eustachian multi-function system comprises a body configured for disposition within a eustachian tube, the body comprising a proximal end, a distal end, a transverse cross-sectional shape, a longitudinally-extending length, an outer wall configured for disposition proximate a wall of the eustachian tube, and an inner portion defining a passageway; and a distal anchor disposed proximate the distal end, the distal anchor configured to releasably anchor the body against the wall of the eustachian tube.

Abstract: An otologic instrument includes a handle configured to be held by a hand of a surgeon and a cannula extending outwardly from the handle and mounted to the handle. An articulated tube is at least partially positioned within the cannula and at least partially extends outwardly from a distal end of the cannula. An actuator is configured to articulate the articulated tube relative to the cannula to position a distal end of the suction tube at a plurality of positions within a three-dimensional volume. The actuator may be configured to control extension of the articulated tube relative to the cannula, the articulated tube having a curved shape when undeformed. The actuator may be configured to pull a cable or push a push rod within the articulated tube to adjust the curvature of the articulated tube.
