Endoscopic Procedures III: Video Capsule Endoscopy

1.3K
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,...

Endoscopic Procedures V: ERCP

6.6K
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 Laproscopy

1.1K
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...

Area of Science:

  • Minimally invasive surgery
  • Medical robotics
  • Gastroenterology

Background:

  • Natural orifice transluminal endoscopic surgery (NOTES) is an emerging surgical technique.
  • Current endoscopic tools have limited dexterity, restricting complex procedures.
  • Existing limitations include access, closure, multitasking, and orientation support.

Purpose of the Study:

  • To address the limitations of conventional endoscopic tools in NOTES.
  • To develop a robotic system enhancing dexterity for endoscopic surgery.
  • To evaluate the feasibility of the MASTER robotic system in animal models.

Main Methods:

  • Development of the Master and Slave Transluminal Endoscopic Robot (MASTER) system.
  • MASTER system features nine degrees of freedom (DOF) in flexible end effectors.
  • Surgical procedures were performed on animal models using the MASTER system.

Main Results:

  • The MASTER robotic system successfully enhanced endoscopic procedures.
  • Complex procedures, including endoscopic submucosal dissections and segmental hepatectomies, were performed in animal models.
  • The system demonstrated increased dexterity and capability compared to conventional tools.

Conclusions:

  • The MASTER robotic system significantly overcomes limitations of conventional endoscopic tools.
  • This robotic platform shows great potential for advancing NOTES procedures.
  • MASTER enables new surgical interventions not previously possible with standard endoscopic equipment.
