[Troca and indicator]

Area of Science:

• Pulmonology
• Medical Devices
• Surgical Instrumentation

Context:

• Tuberculous caverns pose a significant challenge in treating pulmonary tuberculosis.
• Accurate localization of cavitary lesions is crucial for effective intervention.
• Current methods for transthoracic puncture may lack precise intra-cavitary confirmation.

Purpose:

• To introduce a novel photo-indicator trochar for transthoracic puncture of tuberculous caverns.
• To describe the design and function of the trochar-indicator.
• To highlight its utility in the management of cavitary tuberculosis.

Summary:

• A trochar equipped with a photo-indicator is recommended for transthoracic puncture of tuberculous caverns.
• Its simple design allows surgeons to precisely identify when the trochar tip enters the cavern.
• This facilitates safer and more accurate procedures.

Impact:

• The trochar-indicator offers a straightforward method for confirming intra-cavitary placement during procedures.
• It has the potential for widespread adoption in tuberculosis treatment centers.
• Improved accuracy in targeting tuberculous caverns can enhance treatment efficacy.
