We report the case of a video capsule endoscope lodged within a Zenker diverticulum. The system that was equipped with a real-time viewer showed an unchanging image unlike esophageal or gastric mucosa, suggesting that the capsule was elsewhere. The presence of cervical discomfort suggested video capsule retention in a Zenker diverticulum. The capsule was removed endoscopically and reinserted us...

This article introduces briefly recent topics concerning the use of virtual human body (VHB)' in medicine. Potential use of VHB as a model of the human body is first described. Then we summarize the use of VHB fiom two aspects: (a) search or deformation, and (b) using VHB only or both VHB and real body. As examples of each group in this classification, we present virtual endoscope, navigation d...

Abstract Endoscope is an important method for defect detection of metal hose used in rocket engine. Due to the traditional endoscopic technology dependent on manual and low efficiency, this paper introduces Ai Image recognition detect inner surface defects hose. Aiming at problem that most wall bellows are small scale easy be misjudged, a post-processing rechecking model proposed, it strengthen...

A simulation system for flexible endoscopy is described, based on virtual reality techniques. The physician moves the flexible endoscope inside a pipe, in which forces are applied to it. In addition the navigation wheels provide force feedback from the bending of the endoscope’s tip. The paper focuses on the special purpose haptic display which actively generates forces to model the complex int...

Flexible endoscopy is a widely used diagnostic and therapeutic procedure. Contaminated endoscopes are the medical devices frequently associated with outbreaks of health care-associated infections. Accurate reprocessing of flexible endoscopes involves cleaning and high-level disinfection followed by rinsing and drying before storage. Most contemporary flexible endoscopes cannot be heat sterilize...

AIM Insertion of a transanal drainage tube is effective in the management of obstructing colorectal cancer. We devised a new method of inserting the transanal drainage tube safely and quickly using a thin endoscope. METHODS Sixteen patients (seven men and nine women) with obstructive left-sided colorectal cancer were treated by inserting a transanal drainage tube using a thin endoscope. We in...

Flexible endoscopes are used in many surgical procedures and diagnostic exams, like in gastroscopy or colonoscopy. They have also been used recently for endoscopic surgical procedures using natural orifices (NOTES). Flexible endoscopes allow to access operating areas which are not easily reachable, with one small or no incision. However, their manipulation is complex especially for surgical int...

Previous studies and surgeon interviews have shown that most surgeons prefer quality standard de nition (SD)TV 2D scopes to rst generation 3D endoscopes. The use of a telesurgical system has eased many of the design constraints on traditional endoscopes, enabling the design of a high quality SDTV 3D endoscope and an HDTV endoscopic system with outstanding resolution. The purpose of this study w...
