Minimally Invasive Surgery (MIS) has enjoyed increasing attention and development over the last two decades. As MIS systems evolve, the surgeon is increasingly insulated from patient contact, creating a trade-off between surgical sensory information and patient invasiveness. Incorporation of haptic feedback into MIS systems promises to restore sensory information surrendered in favor of minimal...

The function of the esophagus, the first organ of the digestive tube, appears very simple: it is an anteroposteriorly flattened hollow tube organ that transports material from the mouth into the stomach. However, this requires a very complex swallowing mechanism, lubrication of the swallowed material with saliva and other esophageal secretions, transport into the stomach by peristaltic waves, a...

This review discusses the history, developments, benefits, and complications of supraglottic devices in prehospital care for adults and pediatrics. Evidence supporting their use as well as current controversies and developments in out-of-hospital cardiac arrest and rapid sequence airway management is discussed. Devices reviewed include the Laryngeal Mask Airway, Esophageal Tracheal Combitube, L...

PLMA, but we allowed the aspiration catheter to protrude 4 to 5 cm at the end of the drainage tube during insertion (Figure). The aspiration catheter acted as a guide, directing itself and the tip of the mask towards the upper esophageal sphincter. The catheter was easily advanced in the stomach where gastric fluid was aspirated. Subsequently, the catheter was removed and reinserted successfull...

Abstract Actuator plays a significant role in soft robotics. This paper proposed an ultralong stretchable actuator (US 2 A) with variable and sizeable maximum elongation. The US A is composed of silicone rubber tube bellows woven sleeve. maximal extension can be conveniently regulated by just adjusting the wrinkles’ initial angle kinematics could obtained geometrically analyzing structure sleev...

Objective: To raise awareness of this complication of tracheal intubation, to emphasize the gravity due to delayed diagnosis, and to advocate a surgical treatment. Methods: Between April 1980 and January 2000, 97 patients were treated for esophageal perforation in our department. We reviewed the cases of perforation occurring after attempted tracheal intubation. Each case is presented. Discussi...

Experimental, numerical, and theoretical analyses were conducted of the axial load resistance a novel ultrahigh-performance fiber-reinforced concrete (UHPFRC) grouted square hollow section (SHS) tube sleeve connection. The experimental study tested 10 full-scale specimens with varying shear key spacings, grout thicknesses, lengths, volume proportions steel fiber in UHPFRC. Two types failure mod...

Theoretical analysis and finite element method were used to simulate the cold nosing process of commercial purity Aluminum tubes into conical hemispherical dies. The influences parameters, namely initial tube wall thickness, semi-die angle coefficient friction investigated. results obtained in terms load-displacement curves, thickness distribution deformed parts, ratios strain distributions.
