Belt device for simplified CT-guided puncture and biopsy: a technical note

Area of Science:

• Medical Imaging
• Interventional Radiology
• Surgical Devices

Background:

• CT-guided fine-needle punctures are crucial for tissue sampling and interventions.
• Achieving optimal needle trajectory, depth, and position can be challenging, impacting accuracy and safety.
• Existing methods may require multiple adjustments or patient repositioning.

Purpose of the Study:

• To introduce and evaluate a new radiolucent device for CT-guided fine-needle punctures.
• To assess the device's capability in improving the precision of needle placement.
• To streamline the puncture procedure by enabling pre-setting and stationary patient positioning.

Main Methods:

• Development of a novel radiolucent device incorporating a needle holder sheath and goniometric scale.
• The device is designed as a belt for adjustable positioning around the patient.
• Pre-setting of needle parameters (angle, depth, position) based on CT monitor data.

Main Results:

• The device allows precise determination of the optimum angle, depth, and position for fine-needle punctures.
• Needle placement and control scans can be performed with the patient remaining stationary.
• The adjustable design facilitates versatile application during CT-guided procedures.

Conclusions:

• The new radiolucent device significantly enhances accuracy in CT-guided fine-needle punctures.
• It offers a streamlined approach, improving efficiency and potentially patient comfort.
• This innovation represents a valuable advancement in interventional radiology tools.
