Summary
An electromechanical sensor can provide surgeons with tactile feedback during endoscopic surgery by measuring tissue resonance frequencies. This technology enhances intraoperative tissue differentiation and improves safety in head and neck procedures.
Area of Science:
- Biomedical Engineering
- Surgical Technology
- Sensor Development
Context:
- Endoscopic surgery lacks stereoscopic vision and tactile feedback.
- Sensory deficits in minimally invasive procedures pose challenges.
- Need for advanced tools to augment surgeon's capabilities.
Purpose:
- To develop and validate an electromechanical sensor for characterizing tissue properties.
- To compensate for sensory deficits in endoscopic surgery.
- To provide surgeons with tactile information about tissue consistency.
Summary:
- An electromechanical sensor measures tissue resonance frequencies, correlating with hardness.
- Soft tissues resonate between 15-30 Hz, while bone structures range from 240-930 Hz.
- The sensor successfully differentiated healthy, infiltrated, and undermined mucosa in tumors.
Impact:
- Potential to improve intraoperative tissue differentiation in otolaryngological surgery.
- Enhanced tactile information can increase safety in minimally invasive head and neck operations.
- Future integration into surgical instruments offers real-time tissue property assessment.
