Abstract
An endoscope may include a needle and a scope, which may optionally be contained in an elongated shaft. The endoscope may further include a handle comprising at least one button, a visualization component, a reservoir configured to contain a composition, and a dispensing mechanism. The at least one button, the needle, the reservoir, and the dispensing mechanism may be operably linked to cause the composition to be dispensed from the reservoir through the needle to a portion of an ear. A method for using such an endoscope may include inserting the endoscope into a portion of an ear, using the visualization component to visualize the portion of the ear, and pressing the at least one button to dispense the composition from the reservoir through the needle to the portion of the ear.
Core Innovation
The invention relates to a multimodal endoscope that combines a needle and a scope, a handle with at least one button, a visualization component, a reservoir configured to contain a composition, and a dispensing mechanism. The device is operably linked so that pressing the button dispenses the composition from the reservoir through the needle to a portion of the ear. The design supports both visualizing the target area and directly administering various compositions, such as therapeutics or anesthetics, in a controlled and safe manner.
This invention addresses the need for effective and timely management of inner ear disorders such as hearing loss and tinnitus, which are prevalent among military personnel and others exposed to loud noises or blasts. Delivering drugs locally to the middle or inner ear can be challenging due to lack of clinical expertise or specialized tools, especially in remote or deployed settings. Existing systemic or topical treatments are often insufficient or ineffective for inner ear diseases due to biological barriers, and there is an unmet need for a device to safely and easily deliver drugs directly.
The described endoscope enables both transcanal imaging and targeted administration of liquids, gels, or drugs, potentially including features such as a stop component for enhanced safety, integrated high-definition visualization, battery-powered operation for portability, and optional sensors or lasers for precise positioning and feedback. Methods of use include inserting the device into the ear, visualizing the location, advancing or retracting the needle as needed, optionally applying a topical anesthetic, and dispensing the composition to the designated site—all using a single, operator-friendly instrument.
Claims Coverage
The patent contains one independent claim, which defines multiple inventive features regarding the structure and operation of an otoscope with multi-modal capabilities centered on direct, controlled delivery and imaging.
Otoscope integrating needle, scope, visualization, and composition delivery
An otoscope comprising: - A needle and a scope; - A handle with at least one button; - A visualization component; - A reservoir configured to contain a composition; - A dispensing mechanism; - A needle advancement and retraction mechanism for controlling insertion and removal of the needle. These components are operably linked to allow controlled imaging and delivery of compositions into a portion of the ear.
The inventive features outlined in the independent claim define an otoscope system that integrates imaging, needle-based composition delivery, and user controls into a unified, operable device for ear procedures.
Stated Advantages
Provides excellent visualization of ear components, including the ear canal and tympanic membrane, through features such as high-definition imaging, enhanced optics, and a device-integrated display screen.
Portability for use in remote locations is enabled by a compact, battery-powered device without the need for external monitors.
Ease of use via a single instrument for both visualization and composition delivery, simplifying workflow for operators.
Precise delivery of compositions at specified flow rates and doses, well-suited for a range of aqueous and viscous formulations, with quantifiable volume dispensed for documentation.
Improved safety and minimized user errors are facilitated by features such as an optional speculum or stop component for safe placement and stabilization, as well as optional two-laser systems, sensors, and bevel indicators for needle positioning and detection.
Documented Applications
Intratympanic administration of compositions to manage inner ear disorders such as tinnitus and sudden hearing loss, especially following noise or blast exposure.
Local drug or therapeutic delivery to portions of the ear (outer, middle, inner, ear canal, tympanic membrane) with visualization and precise control.
Use in remote or deployed settings where specialized clinical expertise or equipment is unavailable.
