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 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 Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Area of Science:

  • Medical Robotics
  • Surgical Technology
  • Endoscopy

Background:

  • Flexible bronchoscopy lacks crucial distal haptic feedback, posing a risk of iatrogenic tissue trauma.
  • Unobservable tissue damage can occur during endoluminal exploration in current teleoperated systems.

Purpose of the Study:

  • To develop a robot-assisted bronchoscopy system with an integrated dual-modal safety framework.
  • To enhance surgeon situational awareness and mitigate risks of iatrogenic trauma.
  • To improve dexterity and safety in flexible bronchoscopy procedures.

Main Methods:

  • A visual module using image moments for predictive collision avoidance alerts.
  • A Transformer-based network estimating distal interaction torques for real-time haptic feedback.
  • Integration of predictive visual warnings and real-time haptic feedback into a teleoperated system.

Main Results:

  • Phantom validations confirmed the framework's effectiveness in tasks like fragile tissue handling and luminal exploration.
  • Visual warnings significantly reduced excessive force application.
  • The learning-based estimator provided reliable distal force perception.

Conclusions:

  • The dual-modal safety architecture balances operational dexterity with safety in flexible bronchoscopy.
  • The system enhances operator situational awareness, reducing the risk of iatrogenic trauma.
  • Real-time haptic feedback and predictive visual alerts improve safety during robotic bronchoscopy.
