Needle holder for use with a biopsy gun

Area of Science:

• Medical Devices
• Interventional Radiology
• Surgical Instruments

Background:

• Image-guided biopsies are crucial for tissue diagnosis.
• Maintaining precise instrument alignment is essential for accuracy and safety.
• Current methods may present challenges in stability and ease of use.

Purpose of the Study:

• To design and construct a simple needle holder device.
• To evaluate the utility of the device in computed tomography (CT) and ultrasonography-guided biopsies.
• To assess the impact of the device on procedural efficiency.

Main Methods:

• Development of a straightforward needle holder.
• Integration of the holder for stabilizing trocar and cannula before biopsy.
• Removal of the holder prior to biopsy gun attachment and tissue acquisition.
• Application in CT-guided biopsies of liver, pancreas, adrenal gland, and chest wall tumor.

Main Results:

• The needle holder effectively maintained the position of the trocar and cannula.
• Procedural steps were simplified, allowing for quicker instrument setup.
• CT-guided biopsies were performed more easily with the device.
• Successful tissue acquisition was achieved in all cases.

Conclusions:

• The developed needle holder is a simple yet effective tool for image-guided biopsies.
• It enhances procedural efficiency and ease of use in interventional radiology.
• This device represents a practical improvement for biopsy procedures.
