Toward Wireless Implantable Robotic Systems Driven by Magnetic Field for Personalized Therapy

Advanced Robotics Research, EarlyView.
Robotic materials are playing an increasingly vital role in enabling sensing and actuation at small scales. This perspective highlights recent advances in magnetic materials and magnetically actuated devices for wireless sensing, actuation, and energy harvesting toward implantable robotic systems for closed‐loop therapy.

Hybrid Continuum Robot Designs and Architectures for Healthcare Applications

Advanced Robotics Research, EarlyView.
Hybrid continuum robots represent an emerging class of flexible manipulators that blend materials, structures, and actuation concepts from the established fields of soft and continuum robotics. This review introduces an accessible framework to distinguish key hybridization approaches, surveys current designs aimed at complex clinical applications, and ...

Anesthetic management of a patient of multinodular goiter with retrosternal extension presenting with obstructive sleep apnea for total thyroidectomy

Medical Journal of Dr. D.Y. Patil Vidyapeeth, 2018
Multinodular goiter (MNG), one of the disorders of the thyroid gland, is often detected as a mass in the neck, but sometimes produces pressure symptoms. We present successful anesthetic management of a case of an obese woman having MNG with retrosternal ...

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Cascade‐Responsive MXene@Cu‐MOF Heterostructure Integrates Antioxidant Activity, Infection Control, and Vascularization for Tracheal Repair

Advanced Science, EarlyView.
A cascade‐responsive MXene@Cu‐MOF/GelMA hydrogel is engineered as a “skeleton–backpack” platform for extensive tracheal repair. The MXene framework scavenges postoperative ROS and converts NIR light into mild hyperthermia, while the Cu‐MOF component provides pH/NIR‐responsive Cu2+ dosing for infection control, angiogenesis, and chondrogenesis.

Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review

Advanced Intelligent Systems, EarlyView.
This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Comparison of BlockBuster® Laryngeal Mask Airway and Air-Q® Intubating Laryngeal Airway as a conduit for fibreoptic bronchoscopy-guided tracheal intubation in paediatric patients: A randomised comparative study

Indian Journal of Anaesthesia
Background and Aims: The available supraglottic devices (SGDs) used as conduits for fibreoptic bronchoscope-guided intubation (FOI) in children have shown no difference in terms of time taken for tracheal intubation or success rate on the first attempt ...
