Ultrasonic Surgical Assistance Device Design

I need an engineer who can take an ultrasonic concept from idea to a working solution that assists surgeons in the operating theatre. The core requirement is straightforward: produce a medical-grade ultrasonic device whose primary purpose is surgical assistance, rather than diagnostic imaging or therapeutic therapy. Here is what the work entails: • Translate the functional goal—real-time ultrasonic guidance and manipulation during surgery—into a complete architecture, covering transducer selection, drive electronics, signal processing, and ergonomic housing. • Model and optimise the acoustic field so it meets surgical safety limits while giving surgeons the precision and tactile feedback they expect. • Provide all engineering documents: schematics, PCB layout (Altium or KiCad), firmware source (C/C++), and a concise test protocol showing frequency response, power output, and temperature rise under continuous use. • Package your deliverables so a contract manufacturer can move straight to prototype fabrication, including a short bill of materials with vendor links. Accepted work will be demonstrated on a benchtop prototype that hits the target frequency band, operates for at least 30 minutes without overheating, and passes an IEC-60601 leakage current check. A simple video clip plus raw data files will suffice for proof. The procedure type is still open, so I welcome your ideas on whether the design should favour soft-tissue precision or bone-cutting power; just make a clear case and back it with simulations. Experience with piezoelectric transducers, PWM power stages, and medical regulatory pathways will place your bid at the top of my list.
