1. An instrument comprising:
- a handpiece body;
a shaft assembly extending distally from the handpiece body and rotatable relative to the handpiece body, the shaft assembly including an elongate tube with a plurality of shafts coaxially and slidably disposed therein, the elongate tube having (1) a bendable section that can bend within a plane between a linear state and a bent state, (2) a proximal section disposed proximal to the bendable section and defining a longitudinal axis, and (3) a tip disposed distal to the bendable section and configured to engage a tympanic membrane of a patient;
a thumbwheel coupled to the elongate tube and operable to rotate the elongate tube about the longitudinal axis defined by the proximal section of the elongate tube to change an angle of the tip; and
a drive assembly disposed within the handpiece body that can longitudinally translate the plurality of shafts relative to the elongate tube of the shaft assembly including through the bendable section when the bendable section is in the bent state in a predetermined sequence to at least one of pierce the tympanic membrane or deploy a tympanostomy tube into the tympanic membrane.

Abstract
An instrument comprises a shaft assembly, a handpiece body, and a drive assembly. The shaft assembly comprises a plurality of coaxially arranged shafts and a tympanostomy tube. The shaft assembly further includes a flexible section. The shaft assembly extends distally from the handpiece body. The drive assembly is operable to drive the shafts of the shaft assembly in a predetermined sequence to deploy the tympanostomy tube. One or more of the shafts are configured to translate along the flexible section of the shaft assembly as a part of the predetermined sequence to deploy the tympanostomy tube.
