Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

397
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...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

245
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...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

846
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

286
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,...

Oxygen Delivering System III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

1.7K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

40
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Area of Science:

  • Surgical innovation
  • Medical device development
  • Minimally invasive surgery

Background:

  • Minimally invasive surgery (MIS) offers precision but risks a narrow field of view.
  • Surgeons often repeatedly adjust the thoracoscope to ensure safety, increasing procedural burden.
  • A wider, consistent view is crucial for safe and efficient thoracic operations.

Purpose of the Study:

  • To develop a novel device, the panorama vision ring (PVR), to overcome the limited view in MIS.
  • To enable visualization of the entire thoracic cavity during minimally invasive procedures.
  • To reduce surgeon workload and enhance safety in thoracic surgery.

Main Methods:

  • The PVR replaces traditional retractors or trocars, featuring a central port for the thoracoscope and surrounding auxiliary micro-cameras.
  • Image fusion technology combines views from micro-cameras to create a comprehensive panoramic display.
  • The device was evaluated using a 3D thoracic model and in virtual pulmonary lobectomy simulations.

Main Results:

  • The PVR successfully generated a panoramic view encompassing the entire thoracic cavity in simulations.
  • Surgeons could perform virtual pulmonary lobectomies while continuously monitoring the complete surgical field.
  • The device demonstrated its capability to expand the operative view effectively.

Conclusions:

  • The panorama vision ring (PVR) effectively creates a panoramic view of the thoracic cavity using auxiliary cameras during MIS.
  • The PVR has the potential to significantly enhance patient safety and surgeon experience in minimally invasive thoracic procedures.
  • Further development of the PVR aims to make MIS safer and more comfortable.
