Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Area of Science:

  • Neurosurgery
  • Medical Robotics
  • Endoscopic Technology

Background:

  • Neuroendoscopy use has grown significantly over the last two decades.
  • Limited innovation in neuroendoscopic adjuncts and modifications exists.
  • A novel robotic virtual endoscope is proposed to address this gap.

Purpose of the Study:

  • To introduce a robotic virtual endoscope prototype for neurosurgical applications.
  • To enhance safety and control in endoscopic procedures.
  • To explore advancements in virtual field rendition and robotic control for endoscopes.

Main Methods:

  • Development of a prototype endoscope with three degrees of freedom over an 8-year period.
  • Design focused on enhanced safety, virtual field rendition, and robotic control.
  • In vitro testing using a cerebral ventricular model with video or computer interface.

Main Results:

  • Prototype accuracy verified through robotic feedback and viewing angulation assessment.
  • Models demonstrated the endoscope's capability to localize regions via a software interface.
  • The system provides complete visual coverage of 3D space.
