Stewart Platform
Published in Rajesh Singh, Anita Gehlot, Intelligent Circuits and Systems, 2021
Due to its high accuracy and a very rigid design, parallel manipulators are being used for various medical purposes. Two researchers, Jeff M. Wendlandt and S. Shankar Sastry, proposed a prototype having properties similar to that of the Stewart platform in order to implement it for endoscopy [9]. Endoscopy involves the insertion of a thin long tube inside the human body in order to examine specific internal organs and tissues with the help of a camera. This is usually done through the natural openings of the human body such as the mouth or the anus.
Photoacoustic Endoscopy and Its Biomedical Applications
Published in Sihua Yang, Da Xing, Biomedical Photoacoustics, 2020
Endoscopy is an important technique in practical medicine to diagnose internal organs, such as respiratory and gastrointestinal [GI] tracts. The most common technique is video endoscopy, which can provide clear real-time video images of organs' surface to the operator. However, these video images lack depth information and are insufficient to diagnose diseased tissues that develop in endothelial tissues.

Endoscopy is a procedure that allows doctors to view and operate internal organs and vessels of the body by using specialised instruments; for example, flexible tube with attached camera is inserted through small cut or opening in the body. It allows surgeons to view inside the body without making large incisions [27].

A portable, economic system has been created for cooling the brain as well. This system provides efficacy and safety in porcine models (Bakhsheshi et al., 2019). An endoscopy in medicine is a procedure where organs inside the body are looked at using an instrument called an endoscope (a flexible tube with a camera). The emergence of endoscopic imaging techniques allows access to novel developed computer-aided decision support systems (Liedlgruber & Uhl, 2011). A neural fuzzy-based evolutionary system has been proposed to diagnose acute abdominal pain without examining a specialist. The acute abdomen may be caused by a vascular occlusion, infection, inflammation or obstruction. The patient is asked by a computer-based diagnostic system as a multi-choice questionnaire. It can help user get accurate information about the diagnosis and treatment of acute pain, including appendicitis, pancreatitis, diverticulitis and obstructive bowel disease (Towell & Shavlik, 1994).
Simulation for bloodstream conveying bi-nanoparticles in an endoscopic canal with blood clot under intense electromagnetic force
Published in Waves in Random and Complex Media, 2023
Endoscopy is a robust diagnostic device that is extensively used to diagnose and treat gastrointestinal, atherosclerosis, urological, cardiovascular, ophthalmic, and neurovascular diseases. The placing of an endoscopic tube into an artery makes a conduit between the endoscope and the arterial wall, duly modifying the blood flow dynamics within the endoscopic annulus. Endoscopy also brings in additional frictional resistance to the blood flow altering the blood pressure distribution. Researchers have performed many theoretical investigations on endoscopic peristaltic blood flow. Abdelsalam and Bhatti [43] testified the hemodynamical manners of nano blood flow mimicked by a non-Newtonian rheological model inside a peristaltic endoscopic annulated region subject to a radially varying magnetic force. Das et al. [44] have elaborated on the circulation of blood composed of bi-nanoparticles through an endoscopic annulated geometry due to the causation of a powerful electromagnetic force. Das et al. [45] have published an article regarding the electro-osmotic simulation for ionized bloodstream diffused with bi-nanoparticles in a divergent endoscopic ring-shaped domain with the convectively cooling wall condition. The simulated results revealed that the ionized blood flow pattern is markedly modulated inside the flow domain by the electro-osmotic factors. Very recently, Karmakar et al. [46] have performed a computational simulation on the streaming attributes of copper-gold-alumina/blood in an eccentric endoscopic arterial annulus under the sight of electro-osmotic force. Other research works on the endoscopic flow for different fluid models can be listed in Refs. [36,47,48].
