Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A surgical airway procedure is indicated when other forms of endotracheal intubation have failed and ventilation is worsening or not possible. This is the feared "can't intubate, can't ventilate" scenario, and in the emergency setting, cricothyrotomy is the surgical procedure of choice. Cricothyrotomy is preferred over tracheotomy because of the lower risk of complications, the predictable anatomy...

FAQs
The access sheath establishes a guided route from the skin puncture to the target area and helps organize the camera, illumination, and specialized tools within that route. By supporting controlled advancement and device placement, it allows clinicians to perform sampling, drainage, or treatment while reducing unnecessary disruption to surrounding tissue.
Camera and illumination components provide direct visualization of internal structures within confined anatomy. This visual feedback helps clinicians guide instruments toward a target and observe actions such as sampling, drainage, or device placement. For bioengineers, integrating these components into a compact system is important because imaging and tool access must function together through a limited entry path.
Biocompatibility, miniaturization, steerability, and reliable control are central design considerations. Biocompatible materials support safe contact with the body, while smaller components fit through restricted access routes. Steerability helps the system reach a target, and reliable control supports accurate manipulation of instruments during image-guided diagnosis or treatment.
Steerability allows the device or its tools to be directed toward a target within confined anatomy rather than relying only on a straight access path. This capability works with endoscopic visualization and reliable control, helping clinicians position instruments for sampling, drainage, or device placement while limiting disruption to nearby tissue.
The process begins with a small skin puncture through which the access sheath enters the body. The sheath then guides the camera, illumination, and selected tools toward the target. After internal structures are visualized, clinicians can carry out a supported action, such as sampling tissue, draining material, or placing a device.
Clinicians may use a percutaneous endoscopic device for minimally invasive diagnosis or treatment when a target can be reached through a small skin puncture. Its capabilities include internal visualization, sampling, drainage, and device placement. By reducing access-related tissue disruption, the approach can also reduce recovery demands compared with more disruptive access strategies.
Bioengineering research focuses on improving the interaction between the device and confined anatomy. Relevant directions include biocompatible materials, miniaturized cameras and tools, steerable structures, and reliable control systems. The platform also supports advances in image-guided intervention, sensing, and robotic systems, linking mechanical design with clinical diagnosis and treatment needs.
