A portable wireless power transmission system for video capsule endoscopes.
Wireless power transmission (WPT) technology can solve the energy shortage problem of the video capsule endoscope (VCE) powered by button batteries, but the fixed platform limited its clinical application. This paper presents a portable WPT system for VCE. Besides portability, power transfer efficiency and stability are considered as the main indexes of optimization design of the system, which ...
متن کاملWireless Acoustic-Surface Actuators for Miniaturized Endoscopes
Endoscopy enables minimally invasive procedures in many medical fields, such as urology. However, current endoscopes are normally cable-driven, which limits their dexterity and makes them hard to miniaturize. Indeed, current urological endoscopes have an outer diameter of about 3 mm and still only possess one bending degree-of-freedom. In this article, we report a novel wireless actuation mecha...
متن کاملAn integrated vision system with autofocus for wireless capsular endoscopy
A prototype of a vision system for capsular endoscopy provided with autofocus function was developed. It is composed by two main parts: a wireless capsule with an adjustable focus in the range between 15 mm and 100 mm, and a personal computer where the autofocus algorithm is implemented. Several benches and ex vivo tests were performed in order to validate the developed system and encouraging r...
متن کاملA Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks
Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
متن کاملCO2 insufflation versus air insufflation for endoscopic submucosal dissection: A meta-analysis of randomized controlled trials
BACKGROUND Carbon dioxide (CO2) insufflation is increasingly used for endoscopic submucosal dissection (ESD) owing to the faster absorption of CO2 as compared to that of air. Studies comparing CO2 insufflation and air insufflation have reported conflicting results. OBJECTIVES This meta-analysis is aimed to assess the efficacy and safety of use of CO2 insufflation for ESD. METHODS Clinical t...
