Medical device development of surgical instrument

Some projects push every discipline at once, especially in the field of medical device development. Our collaboration with Acoustic Insight, a Delft-based medtech startup, was exactly that kind of project. We helped develop one advanced surgical endoscope for two applications: cochlear implant surgery and middle ear implant surgery.

Surgical endoscope for hearing implant surgery

The device uses optical coherence tomography (OCT). This laser-based imaging technology gives surgeons real-time, high-resolution visuals during delicate ear surgery procedures. The goal is clear: better guidance leads to better outcomes for patients.

We brought design, engineering, and prototyping

Studio Rotor joined forces with Acoustic Insight’s internal team and contributed across the full development process. Our work included both (opto)mechanical design of the internals as well as product design of the enclosure (usability, aesthetics, manufacturability). We also drove prototyping by turning concepts into physical, testable hardware.

Tight constraints in medtech

Working in medtech means navigating tight constraints. Every millimeter counts. Mechanical precision lays the foundation for optical performance. And the device still needs to feel right in a surgeon’s hand. We tackled all of this together.

Two applications, one platform

In the cochlear implant application the endoscope guides surgeons during electrode array insertion. It visualizes the inside of the cochlea through the round window in real time. Surgeons can measure critical anatomical parameters and monitor insertion depth, reducing the risk of damaging delicate inner ear structures.

The middle ear application focuses on reconstructive surgery. The endoscope helps surgeons measure prosthesis length and position with accuracy. Small differences in placement make a big difference to sound transmission. Precise, real-time feedback gives surgeons the control they need.

Built for a regulated, high-stakes medical environment

Developing medical devices demands more than technical skill. It requires clear thinking across disciplines, close collaboration, and a thorough understanding of the clinical context. Studio Rotor brought structured design thinking and hands-on engineering to every stage.

The product remains under development and isn’t medically certified yet. It currently serves research and clinical investigation purposes.
