Abstract

A myringotomy device includes a housing; an elongated tube extending from the housing; and a retractable cutting tool extendable through the elongated tube, the cutting tool comprising a blade. The cutting tool is configured such that when advanced, the blade of the cutting tool extends beyond a distal end of the elongated tube. The cutting tool is also configured such that when retracted, the blade is retracted into the elongated tube and a fluid conduit is created from the distal end of the elongated tube to the housing.

Claims

1. A myringotomy device, comprising:

a housing;

an elongated tube extending from the housing;

a retractable cutting tool extendable through the elongated tube, the cutting tool comprising a blade; and

a cannula extendable through the elongated tube, wherein the cutting tool is disposed within the cannula;

wherein the cutting tool is configured such that when advanced out of the elongated tube, the blade of the cutting tool extends beyond a distal end of the elongated tube and seals the elongated tube; and

wherein the cutting tool is configured such that when retracted, the blade is retracted into the elongated tube and a fluid conduit is created from the distal end of the elongated tube to the housing;

wherein when the cutting tool is retracted within the cannula, a weep hole in the cannula is configured to be covered by at least a portion of the cutting tool to cause the fluid conduit to be created.

2. The myringotomy device of claim 1, further comprising a pinion in the housing and a carrier rack on the retractable cutting tool, the pinion and the carrier rack being configured to cooperably cause the extension and retraction of the cutting tool.

3. The myringotomy device of claim 1, further comprising a suction hose attached to the housing, the suction hose being configured to provide suction when the fluid conduit is created.

4. The myringotomy device of claim 1, further comprising a cutting tool extension button on the housing, the cutting tool extension button being configured to selectively extend or retract the cutting tool relative to the elongated tube.

5. The myringotomy device of claim 1, further comprising an ear tube delivery tool extendable through the elongated tube.

6. The myringotomy device of claim 1, wherein the elongated tube is flexible to allow the housing to be positioned out of a line of sight of a user.
