Endoscopic Studies II: Thoracocentesis

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...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

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 interventions are...

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

Oxygen Delivering System III: Tracheostomy and T-piece

Oxygen Delivering System III: Tracheostomy and T-piece

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...

Endoscopic Procedures III: Video Capsule Endoscopy

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...

Area of Science:

Thoracic Surgery
Surgical Technology
Medical Imaging

Background:

Video-assisted thoracic surgery (VATS) presents challenges in hand-eye coordination and spatial understanding for surgical teams.
Conventional VATS requires operators and assistants to frequently shift focus between the patient and distant monitors, potentially hindering workflow.

Purpose of the Study:

To develop and evaluate a new display system for VATS designed to improve ease of use and safety.
To enhance the surgical team's ability to perform VATS by addressing limitations in visual feedback and coordination.

Main Methods:

Development of a novel display system integrated with an original thoracoscope.
The system features a monitor positioned approximately 10 cm from the chest wall, directly above the operative field.
Evaluation of the system's impact on operator and assistant performance, including instrument handling and spatial awareness.

Main Results:

The new display system allows simultaneous viewing of the patient and monitor, improving visual integration.
Enhanced hand-eye coordination and three-dimensional understanding were observed compared to conventional thoracoscopy.
The system facilitated good and easy instrument handling, comparable to standard thoracotomy procedures.

Conclusions:

The developed VATS display system offers a significant improvement in surgical workflow and safety.
This innovation addresses key challenges in VATS, making the procedure more accessible and efficient, especially for assistant surgeons.
The system's design promotes better spatial awareness and instrument manipulation during thoracic procedures.
