A new surgical tool to protect delicate tissues during spinal procedures
Development of a Multispectral Kerrison Rongeur for Dura and Nerve Root Detection
This project aims to create a specialized surgical instrument with a built-in sensor to help surgeons avoid accidentally harming nerves and the protective covering of the spinal cord during back surgery.

What this research studies
Spinal surgeries sometimes involve a risk of damaging delicate structures like the dura (the protective sac around the spinal cord) and nerve roots, which can lead to serious complications. Currently, surgeons rely on their skill to keep these tissues safe, but they lack a direct way to see or identify them during critical moments. This project is developing a modified Kerrison rongeur, a common bone-removing tool, to include a tiny optical sensor. This sensor would allow surgeons to detect the dura and nerve roots in real-time, helping them to operate more safely and precisely.
Who could benefit from this research
Good fit: Patients undergoing spinal surgery, particularly those requiring bone removal near the spinal cord and nerve roots, could potentially benefit from this technology in the future.
Not a fit: Patients not undergoing spinal surgery or those whose procedures do not involve the use of a Kerrison rongeur would not directly benefit from this specific device.
Why it matters
Potential benefit: If successful, this new surgical tool could significantly reduce the risk of nerve and dura damage during spinal surgeries, leading to fewer complications and better patient outcomes.
How similar studies have performed: While the concept of integrating optical sensors into surgical tools is emerging, this specific application for real-time dura and nerve root detection in a Kerrison rongeur is novel and currently untested in this form.
