Adequate stabilization in scrotal and penile surgeries is essential but traditionally relies on manual fixation, causing assistant fatigue and operative instability.
Technical Solution
We developed the Nuts Holder, an adjustable, reusable stainless steel support device featuring a screw-and-slide mechanism designed to gently clamp and stabilize the target organ.
Proof of Concept
In 16 consecutive urological cases, including microTESE, the device was successfully applied without any complications. A surgeon survey demonstrated 100% agreement on improved operative stability, reduced assistant dependence, and enhanced maintenance of microscopic focus.
Next Steps
To address an initial learning curve regarding setup ease, a second-generation model featuring a quick-release mechanism and reduced weight is currently under development.
Conclusion
The Nuts Holder is a safe and feasible device that standardizes tissue fixation, prevents assistant-related instability, and successfully facilitates solo surgery in urology.
