Human Endoscopic Ultrasonography

Gastroenterology, 1982
Conventional transcutaneous ultrasound examinations are often compromised by intervening pulmonary or bowel gas and have limited resolution. Ultrasonic probes of frequencies greater than 5 MHz, which enhance resolution, cannot be used successfully on the skin surface, because they do not penetrate deeply enough to view intraabdominal organs in most ...

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful
