What changed
USPTO published patent application US20260096931A1 for a micro-actuator system designed for inner ear injection and sampling surgery. The invention comprises a microneedle puncture mechanism embedded in a driving and sensing module, installed on a high-precision linear driving module with an end-effector mechanism and endoscope camera for real-time surgical imaging. A tension sensor monitors steel wire tension for safe intra-ear interaction.
Affected parties should monitor this application for eventual grant or rejection. Medical device manufacturers developing similar inner-ear surgical instruments may face potential infringement claims once the patent issues. Healthcare providers performing inner-ear procedures should be aware that this technology may become available for licensing or purchase.
What to do next
- Monitor for patent grant status
- Review claims for infringement analysis

Abstract
A micro actuator for inner ear injection and sampling surgery is provided. The microneedle puncture mechanism module is embedded in the driving and sensing module. The driving and sensing module is installed on the high-precision linear driving module. The end-effector mechanism module is installed in the front of the driving and sensing module. The microneedle puncture mechanism module passes through the end operating mechanism module and extends. An endoscope camera module located in the end-effector mechanism module provides real-time images of a surgical process. A tension sensor in the driving and sensing module monitors tension changes of steel wires in real time to ensure safe interaction with the intra-ear environment.
